In order to enlarge the pool of knowledge available in the public domain, temporary exclusive rights are granted to innovators who are willing to fully disclose the information needed to reproduce their invention. After the 20-year patent protection period elapses, society should be able to make free use of the publicly available knowledge described in the patent document, which is deemed useful. Resistance to pesticides destroys however the usefulness of information listed in patent documents over time. The invention, here pesticides, (...) will have a decreased effectiveness once it enters the public domain. In some cases pesticides lose most of their efficacy shortly after temporary exclusive rights expire. Society’s share of the patent bargain—having new useful knowledge available in the public domain—is lost. Resistance can be slowed down, if pesticide use is limited by optimal compliance. Stimulating proper use is generally not compatible with existing market incentives for patent holders, since these have to be able to maximize profits in order to recoup research and development costs and satisfy obligations to the company’s stakeholders. Another incentive system is needed to ensure longevity of pesticides, which at the same time does not hamper future research. (shrink)

Climate change is considered as the global challenge in the 21st century. Anthropogenic activities have directly led to an immense increase in green house gas emissions mainly carbon dioxide that contributes mainly in the warming of atmosphere. The concentration of carbon dioxide is expected to rise twice as high as those existing in pre-industrial period, within the next century. Pesticides are the biological pollutants, which are being used by the man to kill the pests for increasing the yield of many (...) crops and insect vectors to control the spread of disease. The tremendous use of pesticides has caused severe health hazards to organisms including human beings due to climate change. Excessive use of pesticides may lead to the destruction of biodiversity. Many birds, aquatic organisms and animals are under the threat of harmful pesticides for their survival. The pesticides effects are lessen by organizing awareness program among the farmers, gave special training to them regarding consequences of pesticides, their screening and monitoring methods.

Pesticides remain an integral part of development efforts to renew economic growth in Central America and lift the region out of a severe economic crisis. This paper analyzes the implications of the continued reliance on pesticides for heightening economic and ecological problems in the agrarian sector.Relying on a case study of export melon production in Choluteca, Honduras, the author argues that current development strategies, which rely heavily on pesticides, are generating ecological disruption that creates conditions biased against small producers. Lack (...) of knowledge of the hazards inherent in the technology and the resulting emergence of pesticide resistant pests, crop losses, environmental contamination, and public health problems, pose serious obstacles to the survival of small-scale producers. Meanwhile transnational and other flexible, large scale operations often adapt to such conditions, and on occasion may even turn such problems to their benefit. The author concludes that economic growth may only be sustainable when questions of social equity and ecological viability are brought to the forefront of U.S. development strategies. (shrink)

When the Environmental Protection Agency banned DDT late in 1972, environmentalists hailed the decision. Indeed, the DDT ban became a symbol of the power of environmental activism in America. Since the ban, several species that were decimated by the effects of DDT have significantly recovered, including bald eagles, peregrines, ospreys, and brown pelicans. Yet a careful reading of Rachel Carson’s Silent Spring reveals DDT to be but one of hundreds of chemicals in thousands of formulations. Carson called for a reduction (...) in the use of all chemical insecticides. Carson’s recommendations notwithstanding, policymakers focused on DDT and other chlorinated hydrocarbons, culminating in the DDT ban, passage of the Federal Environmental Pesticide Control Act of 1972, and subsequent bans on aldrin and dieldrin. Similarly, the history of pesticides has focused inordinately on DDT, providing a myopic image of the ongoing challenges of pesticides in agricultural practice and ongoing environmental protection efforts in the modern world. “Pesticides and the perils of synecdoche” argues that focusing on DDT oversimplified the environmental risks of chemical insecticides and narrowed the parameters of the debate, and in the process both policy and subsequent histories neglected the highly toxic organophosphate insecticides, which dominated agriculture in the United States and the world after the DDT ban, with unintended consequences for farmworkers and wildlife.

The decision to accept or to reject an empirical hypothesis concerning the risks and hazards of a pesticide requires assessing the cost's of error if the wrong decision is taken. The assessment of such costs involves scientists in problems which are closely related to those which policy‐makers face in deciding what to do in view of the information provided by scientists. These problems include the unforeseeable effects of agricultural technologies, the assessments of costs and benefits, and the choice of (...) decision rule to use in policy formation. I conclude that the combined impact of these problems motivates the use of prudentially weighted decision rules in forming policies which regulate the use of pesticides, and it motivates the development of bio‐environmental alternatives to chemically based pest control policies.

Despite the application of 2.5 million tons ofpesticides worldwide, more than 40% of all potentialfood production is lost to insect, weed, and plantpathogen pests prior to harvest. After harvest, anadditional 20% of food is lost to another group ofpests. The use of pesticides for pest control resultsin an estimated 26 million human poisonings, with220,000 fatalities, annually worldwide. In the UnitedStates, the environmental and public health costs forthe recommended use of pesticides total approximately$9 billion/yr. Thus, there is a need for alternativenon-chemical (...) pest controls, and genetic engineering(biotechnology) might help with this need. Diseaseand insect pest resistance to various pests has beenslowly bred into crops for the past 12,000 years;current techniques in biotechnology now offeropportunities to further and more rapidly improve thenon-chemical control of disease and insect pests ofcrops. However, relying on a single factor, like theBacillus thuringiensis toxin that has beeninserted into corn and a few other crops for insectcontrol, leads to various environmental problems,including insect resistance and, in some cases, athreat to beneficial biological control insects andendangered insect species. A major environmental andeconomic cost associated with genetic engineeringapplications in agriculture relates to the use ofherbicide resistant crops (HRC). In general, HRCtechnology results in increased herbicide use but noincrease in crop yields. The heavy use of herbicidesin HRC technology pollutes the environment and canlead to weed control costs for farmers that may be2-fold greater than standard weed control costs. Therefore, pest control with both pesticides andbiotechnology can be improved for effective, safe,economical pest control. (shrink)

The global pesticide complex has transformed over the past two decades, but social science research has not kept pace. The rise of an enormous generics sector, shifts in geographies of pesticide production, and dynamics of agrarian change have led to more pesticide use, expanding to farm systems that hitherto used few such inputs. Declining effectiveness due to pesticide resistance and anemic institutional support for non-chemical alternatives also have driven intensification in conventional systems. As an inter-disciplinary (...) network of pesticide scholars, we seek to renew the social science research agenda on pesticides to better understand this suite of contemporary changes. To identify research priorities, challenges, and opportunities, we develop the pesticide complex as a heuristic device to highlight the reciprocal and iterative interactions among agricultural practice, the agrochemical industry, civil society-shaped regulatory actions, and contested knowledge of toxicity. Ultimately, collaborations among social scientists and across the social and biophysical sciences can illuminate recent transformations and their uneven socioecological effects. A reinvigorated critical scholarship that embraces the multifaceted nature of pesticides can identify the social and ecological constraints that drive pesticide use and support alternatives to chemically driven industrial agriculture.

The costs of agricultural inputs added to those of labor represent almost a third of the total cost of Brazilian sugarcane production. This study analyzes the behavior of the price per ton of sugarcane in Brazil, relating it to the main production costs of this cultivation. Twelve price indicators from January 2015 to December 2020 were evaluated. First, the data were adjusted to a multiple linear regression model to identify the significant variables on variation in the price per ton of (...) sugarcane. Then, the Monte Carlo simulation was used to measure the level of certainty of occurrence of these variables, and forecasts were obtained from the adjustment of ARIMA models.

Controversies in food and agriculture abound, with many portrayed as conflicts between polarized viewpoints. Framing such controversies as dichotomies, however, can at times obscure what might be a plurality of views and potential common ground on the subject. We used Q methodology to explore stakeholders’ views about pesticide safety, agricultural worker exposure, and human health concerns in the tree fruit industry of central Washington State. Using a purposive sample of English and Spanish-speaking agricultural workers, industry representatives, state agencies, educators, (...) and advocates, participants sorted 45 statements on pesticide use and perceived human safety risks in the tree fruit industry in 2011. We used PQMethod 2.33 statistical software program to identify viewpoints, based on differences between how participants sorted the statements. The results revealed three distinct viewpoints among 38 sorters that explained 52 percent of the variance. The viewpoints included the: skeptics who expressed concern over the environmental and human health impacts of pesticide use; acceptors who acknowledged inherent risks for using pesticides but saw the risks as known, small and manageable; and incrementalists who prioritized opportunities to introduce human capital and technological improvements to increase agricultural worker safety. We then brought representatives with these different viewpoints together to analyze the results of the Q study, and to brainstorm mutually acceptable improvements to health and safety in tree fruit orchards. In describing and analyzing this case study, we argue that Q methodology can serve as one potentially effective tool for collaborative work, in this case facilitating a process of orchard safety improvements despite perceived stakeholder polarization.

Exposure to pesticides during infancy is associated with numerous adverse health outcomes. The assessment of knowledge and perception of pesticides exposure and risk among children has not been thoroughly studied. The aim of the study was to evaluate the reliability and validity of a questionnaire that measures the knowledge and perception of exposure to organophosphate pesticides among rural schoolchildren. The questionnaire was administered to 151 schoolchildren between 9 and 13years from four Chilean rural schools. An internal consistency analysis of the (...) ordinal alpha coefficient and a polychoric factor analysis for categorical data were used. The results show that the ordinal alpha was 0.95. Polychoric matrices of rotated components show the 17 questions summarized pesticide knowledge in five factors extracted after promax rotation. This factorial model explains 56.3% of the variance. The questions were grouped as follows: knowledge about pesticides ; knowledge of health effects related to pesticides exposure ; pesticide exposure through the growing of fruits and vegetables ; perception and action against pesticides exposure at school ; and perception and action against pesticides exposure at home. The questionnaire provides a useful tool for examining pesticide exposure in agricultural regions, allowing younger community members to participate. (shrink)

This paper investigates the local implementation of Malaysian public GAP standard called MyGAP by examining its effectiveness in raising the awareness and improving the pesticide use practices of participant smallscale farmers toward better food safety and quality assurance. For this objective, 19 MyGAP certified and 57 uncertified durian farms in the state of Pahang, Malaysia were surveyed. The research found that certified farm managers have a much better understanding of the basic intent of the policy than uncertified farms, (...) reflecting the individually oriented interests and motivations of participant farmers in the national scheme. Their interests in and assessment of the merits of the scheme are found to concentrate in economic realms rather than in the original policy goal of food safety and quality assurance. As regards pesticide use practices, certified farms showed a much better performance than uncertified farms in record keeping and pesticide use and management. There remains a question, however, whether it is due to the farming practices improved through MyGAP adoption or due to the participation of farms already well-performing prior to MyGAP adoption.

How do “international” epistemic communities shape regulatory contests between transnational firms and civil society organizations in the Global South? With the establishment of the World Trade Organization, member states committed to basing trade-restrictive national regulations on science-based “international” standards set by “international” standard-setting bodies. Yet we know little about how the WTO regime has shaped the operation of epistemic communities within standard-setting bodies and, in turn, how standard-setting bodies articulate with national policy-making processes in the Global South. Building on work (...) in the new political sociology of science, I argue that neoliberal globalization and the establishment of the WTO have created incentives for Western epistemic communities to at once cast themselves as “international” under the WTO regime and orient their scientific agendas toward the priorities of transnational firms. Moreover, this transformation of epistemic communities has created opportunities for transnational firms facing contentious policy environments in the Global South to effectively outsource regulatory decision-making to “international” epistemic communities that can claim legal status under the WTO regime. Empirically, I focus on the case of one Western epistemic community—the Association of Analytical Communities International—and its claim to epistemic jurisdiction over pesticide residue standards for soft drinks in India.

Transgenic insecticidal Bt crops are being increasingly used worldwide, and concern is increasing about resistance and their effects on nontarget organisms. The toxin acts as a weak pesticide and, hence, the effects are subtler than those of chemical biocides. However, the toxin is ever present, but concentrations vary with age of plant and plant subunit, causing varying lethal and sublethal effects on pest survival, developmental time, and fecundity. Refuges for susceptibility to Bt occur spatially in non-Bt hosts and temporally (...) within the crop because of time-varying toxicity and pest tolerance. Natural enemies feeding on Bt-intoxicated prey may have reduced longevity and, likely, fecundity that reduces their efficacy in controlling pest populations, and pest resurgence and secondary pest outbreaks may occur that may require insecticide use. System modeling is proposed as an efficient tool for examining the use of extant and future biotechnologies in pest control. (shrink)

Today, one out of every six children suffers from some form of neurodevelopmental abnormality. The causes are mostly unknown. Some environmental chemicals are known to cause brain damage and many more are suspected of it, but few have been tested for such effects.

The brain's development is uniquely sensitive to toxic chemicals, and even small deficits may negatively (...) impact our academic achievements, economic success, risk of delinquency, and quality of life. Chemicals such as mercury, polychlorinated biphenyls, arsenic, and certain pesticides pose an insidious threat to the development of the next generation's brains. When chemicals in the environment affect the development of a child's brain, he or she is at risk for mental retardation, cerebral palsy, autism, ADHD, and a range of learning disabilities and other deficits that will remain for a lifetime.We can halt chemical brain drain and protect the next generation, however, and Grandjean tells us how. First, we need to control all of the 200 industrial chemicals that have already been proven to affect brain functions in adults, as their effects on the developing brain are likely even worse. We must also push for routine testing for brain toxicity, stricter regulation of chemical emissions, and more required disclosure on the part of industries who unleash hazardous chemicals into products and the environment. Decisions can still be made to protect the brains of future generations."In his crisply written, deeply documented book, Dr. Philippe Grandjean, renowned physician and public health specialist, describes the exquisite vulnerability of the developing human brain to toxic chemicals in the environment, a vulnerability that he ascribes to the brain's almost unimaginable complexity. Today, nearly one in 6 children is born with a neurodevelopmental disorder - a birth defect of the brain. One in 8 has attention deficit disorder. One in 68 is diagnosed with autism spectrum disorder. These rates are far higher than those of a generation ago, and, although they are less publicized, the problems are more prevalent than those caused by thalidomide in the 1960's. The increases are far too rapid to be genetic. They cannot be explained by better diagnosis. How then could they have come to be? Dr. Grandjean has a diagnosis -- the thousands of toxic chemicals that have been released to the environment in the past 40 years with no testing for toxicity. David P. Rall, former Director of the US National Institute of Environmental Health Sciences, once stated that 'If thalidomide had caused a ten-point loss of IQ rather than obvious birth defects of the limbs, it would probably still be on the market'.

In future decades, food demand for an increased population with elevated standards of living poses a huge challenge, particularly in the sense of the environmental impacts of agricultural systems. We have analyzed agricultural data from the past 50 years, and found that the current agricultural practices will have negative effects on global food production: total agricultural area has decreased since 2000, fertilizer and pesticide consumption increased while their efficiency decreased, and available water sources are already being used for irrigation. (...) Expansion of biofuel production, cultivation limitations of genetically modified organisms, and the trend of increasing living standards will all intensify the risks of a global food crisis in the coming decades. Crop yield and environmental protection will then have to be traded off if there are no feasible solutions at country or regional scales, and it is crucial for agricultural sustainability to increase crop yields and simultaneously decrease environmental impacts of agriculture intensification.

Recent research has pointed to the importance of the prenatal environment in the etiology of autism spectrum disorder (ASD) but the biological mechanisms which mitigate these environmental factors are not clear. Mitochondrial metabolism abnormalities, inflammation and oxidative stress as common physiological disturbances associated with ASD.

These leading prenatal environmental factors were found to be most associated with inflammation, (...) followed by oxidative stress and mitochondrial dysfunction. Other prenatal factors associated with ASD not identified by the network analysis were also found to be significantly associated with these common physiological disturbances. A better understanding of the biological mechanism which mediate the effect of prenatal environmental factors can lead to insights of how ASD develops and the development of targeted therapeutics to prevent ASD from occuring.

Our study in China of two Integrated Pest Management (IPM) training programs for farmers shows that one is more effective than the other in reducing pesticide applications as well as in imparting to farmers an understanding of the rice ecosystem. The two training programs are based upon two different paradigms of IPM. This article uses a triangulated method of measuring concept attainment among farmer trainees in China as one measure of the effectiveness of training. Concepts of insect ecology (...) brought about by training, as well as persistence of concepts one year after training, are measured. This information is compared to farmer data on pesticide applications and yields in order to determine the comparative effectiveness of two models of IPM farmer training in Sichuan Province. Results indicate that the Farmer Field School (FFS) model of training, based upon a new Ecology-Based IPM paradigm, is more effective than the 3 Pests 3 Diseases (3P3D) model based upon an older Economic Threshold IPM paradigm. Crop yield results and pesticide applications by farmers after training are also used to indicate which of these paradigms of insect pest control is more effective, hence scientifically accurate.

The chief sources of groundwater contamination on farms come from point sources and diffuse sources. Possible point sources are feedlots, poorly-sited manure piles, septic sewage-treatment systems—all of which can release nitrate, phosphates and bacteria— and sites of chemical spills. Diffuse sources are typified by excess fertilizer leaching from a number of arable fields. The basis of quality standards for drinking-water is discussed in relation to common contaminants present on farms. Samples of drinking-water were collected in 1991–1992 from wells on about (...) 1,200 farms in order to study the quality of rural groundwater in Ontario. Analysis showed that approximately one third of wells were contaminated with bacteria, 14% were contaminated with nitrate, two wells were contaminated with pesticide, but 40% were considered unsafe because of the presence of at least one contaminant. These values were similar to those reported for similar regions in the U.S. There was no significant effect of agricultural practice on the proportion of contaminated samples. One response of Ontario's farmers to information on water quality has been to initiate their own program, the Environmental Farm Plan, which has 23 modules by which the risk of environmental contamination can be assessed. Government policies for agriculture can be expected to influence farming practices. However, the literature suggests that the consequences of policies aimed at reducing environmental contamination are poorly understood, not least because the instruments used for implementation can have widely differing impacts. The need for discussions on the ethics surrounding the relationship between food producers and consumers with regard to environmental contamination is identified. (shrink)

This article examines the construction of image recognition algorithms for the classification of plant pathology problems. Rooted in science and technology studies research on the effects of agricultural big data and agricultural algorithms, the study ethnographically examines how algorithms for the recognition of plant pathology are made. To do this, the article looks at the case of a German agtech startup developing image recognition algorithms for an app that aims to help small-scale farmers diagnose plant damages based on digital images (...) of their symptoms. The study posits that the construction of these algorithms can be grasped as a succession of layers, at each of which the startup’s employees carry out different selection practices. It is argued that these practices gradually inscribe a selective recognition of the phenomenon of plant pathology into the algorithms of the app. This selective recognition is reflected in the fact that the emerging algorithms are effective in identifying isolated plant damages on isolated crops, while ignoring most agroecosystem-related actors and relations through which plant damages arise. The article concludes that the app’s selective recognition of plant pathology is likely to perpetuate or even exacerbate the pesticide use of its users. This is because the app’s view of plant pathology as a phenomenon comprised of isolated plant damages on isolated crops is more compatible with the use of chemical pesticides than with approaches to crop protection that strive for a more moderate use of these substances (e.g., integrated pest management, agroecology, organic agriculture).

The conventional production model based on extensive use of chemical inputs such as pesticides is increasingly challenged. Organic agriculture is considered as one of the most important alternative agricultural systems to produce healthy food without any chemicals. Current models are not suitable for prediction of environmental behaviors. The current study aims to analyze the diffusion of organic agriculture to produce healthy food with the environmental sociology approach among farmers. The study was conducted using the survey research and multi-stage random sampling (...) in Fars province, in the south of Iran. The samples included 215 farmers. The reliability of the questionnaire was confirmed by conducting a pilot study out of the main sample. The results showed that the farmers have strong attitude to the environment and are for the most part, highly intentioned to perform organic activities. Based on the results, the farmers’ intention toward adoption of organic agriculture, environmental identity, and responsibility of pro-environmental behavior, and their moral norms play an important role to accept organic agricultural activities. There are also some effective factors in implementation of organic agriculture including farmers` increasing awareness about the principles of organic farming, controllability of environmental behaviors as well as their accessibility to the resources and facilities for organic farming. The study emphasized that the attitude and enhancing the knowledge do not lead to pro-environmental behaviors and organic activities directly. Using the models and environmental sociology theories is more efficient to explain pro-environmental behaviors. To this aim, some suggestions were presented to increase the adoption of organic activities and persuade the Iranian farmers to select this kind of cultivation. (shrink)

Metaseiulus occidentalis is a representative of an important family of mites (Arthropoda: Chelicerata: Acari: Phytoseiidae) that are effective predators of pest mites in agricultural crops around the world. Like many arthropods, this mite contains multiple genomes, including the genomes of several microbial symbionts as well as its own mitochondrial and nuclear genomes. The mitochondrial genome is “mitey” large at 25 kb, due to duplication and triplication of genes. By contrast, the nuclear genome is “mitey” small at 88 Mb. This mite (...) has a parahaploid genetic system, tolerates inbreeding, and has a haploid chromosome number of 3. This predator was genetically improved for use in agriculture by developing strains that lacked the ability to overwinter in diapause or were resistant to multiple pesticides, and can be genetically modified using recombinant DNA methods. Sequencing the nuclear genome would provide useful insights that could enhance genetic improvement programs that would result in improved pest management, could provide genes needed to resolve the evolutionary relationships of this family, and could serve as a model for understanding the evolution and genetics of chelicerate arthropod predators.

In 1943, Allied forces in recently liberated Naples were confronted with an outbreak of louse-borne typhus. The established Anglo-American narrative of that epidemic is a triumphant story of effective action that controlled the disease with unprecedented speed and success, aided by the pioneering use of the pesticide DDT. Rather than retell that tale, this article discusses why the outbreak and its ending are largely absent from Italian accounts of wartime Naples. Drawing on Italian sources and contemporary Allied ones, it (...) argues that this absence speaks powerfully to the realities of life for Neapolitans at the time. These realities included the likelihood that the epidemic left most people unscathed, and the presence of additional challenges that made survival in the city perilous. Illustrating how tangled events (and even non-events) can be fashioned into simplistic but meaningful frameworks according to the perspective and priorities of the observer, the article also demonstrates how methods (in this case, delousing with insecticide) that were later proclaimed as crucial in ending an epidemic can be viewed very differently by populations required to comply with them, especially when the disease's dangers seem remote.

On November 28, 2009, as part of events marking the twenty-fifth anniversary of the disaster at the Union Carbide plant in Bhopal, gas survivors protested the contents of the report prepared by government scientists that mocked their complaints about contamination. The survivors shifted from the scientific document to a mediated lunch invitation performance, purporting to serve the same chemicals as food that the report had categorized as having no toxic effects. I argue that the lunch spread, consisting of soil and (...) water from the pesticide plant, explicitly front-staged and highlighted the survivor’s forced intimate relationship with such chemicals, in order to reshape public perception of risks from toxins. Chemical matter like sevin tar and naphthol tar bound politicians, scientists, corporations, affected communities, and activists together, as these stakeholders debated the potential effects of toxic substances. This gave rise to an issue-based “chemical public.” Borrowing from such theoretical concepts as “ontologically heterogeneous publics” and “agential realism,” I track the existing and emerging publics related to the disaster and the campaigns led by the International Campaign for Justice in Bhopal advocacy group.

Background To describe the preferences for disclosure of individual biomarker results among mothers participating in a longitudinal birth cohort. Methods We surveyed 343 mothers that participated in the Health Outcomes and Measures of the Environment Study about their biomarker disclosure preferences. Participants were told that the study was measuring pesticide metabolites in their biological specimens, and that the health effects of these low levels of exposure are unknown. Participants were asked whether they wanted to receive their results and their (...) child's results. In addition, they were asked about their preferred method (letter vs in person) and format (more complex vs less complex) for disclosure of results. Results Almost all of the study participants wanted to receive their individual results (340/343) as well as their child's results (342/343). However, preferences for receiving results differed by education level. Mothers with less than a college degree preferred in-person disclosure of results more often than mothers with some college education or a college degree (34.3% vs 17.4% vs 7.9%, p<0.001). Similarly, mothers with less than a college education preferred a less complex disclosure format than mothers with some college education or a college degree (59.7% vs 79.1% vs 86.3%, p<0.0001). Conclusion While almost all study participants preferred to receive results of their individual biomarker tests, level of education was a key factor in predicting preferences for disclosure of biomarker results. To ensure effective communication of this information, disclosure of biomarker results should be tailored to the education level of the study participants. (shrink)

The study constructs a theoretical model of social capital, farm household financing, and scale operation and their environmental effects, and conducts an empirical test based on data from China Family Panel Studies which is conducted in 2018 using causal mediation analysis. The results showed that farmers who spent more on human interaction have a higher probability of choosing scale operation by renting land, the mechanism of which is that the social capital accumulated by farmers based on human interaction facilitates their (...) access to formal and informal financing, which in turn alleviates the financing constraint of scale operation. In addition, we found that the farmers with low education were more dependent on social capital to obtain informal financing to achieve scale operation. The environmental effects of scale operation found that the farmers significantly reduced the proportion of fertilizer and pesticide use, which could effectively mitigate possible pollution problems caused by excessive fertilizer and pesticide use. These findings confirm that social capital can alleviate the financing constraints of farmers to expand their operation scale through formal and informal financing, which in turn has a positive environmental effect.

Health policy frameworks usually construe environmental protection and human health as harmonious values. Policies that protect the environment, such as pollution control and pesticide regulation, also benefit human health. In recent years, however, it has become apparent that promoting human health sometimes undermines environmental protection. Some actions, policies, or technologies that reduce human morbidity, mortality, and disease can have detrimental effects on the environment. Since human health and environmental protection are sometimes at odds, political leaders, citizens, and government officials (...) need a way to mediate and resolve conflicts between these values. Unfortunately, few approaches to applied bioethics have the conceptual tools to do accomplish this task. Theories of health care ethics have little to say about the environment, and theories of environmental ethics don’t say much about human health. In this essay, I defend an approach to ethical decision-making that gives policy-makers some tools for balancing promotion of human health and protection of the environment. (shrink)

Over the past several decades, urban community gardens have arisen in diverse and economically compromised neighborhoods across the U.S. as part of multiple environmental justice efforts. Urban community gardens have enabled users to mitigate the effects of many environmental injustices such as the impact of food deserts, nutrient poor food found at convenience stores, and pesticide laden grocery items. While these benefits have promulgated across the U.S., community gardens are also well known to be located in historically contaminated locations (...) in urban landscapes. These landscapes include former brownfield sites, superfund sites, and other abandoned spaces of contamination. Although environmental justice efforts to reclaim healthy food in urban community gardens are commendable, the presence and effects of potentially harmful contaminants is often overlooked as gardens are established. Further, governmental organizations tasked with protecting human health, such as the Environmental Protection Agency, have not established any health standards for urban community gardens. This creates many challenges in determining what is safe in community gardens, and garden mangers and users are often unaware of how severe the impacts of contamination may be or how to mitigate its effects. In this study, I highlight the prevalence of harmful concentrations of contaminants in urban community gardens in and near Seattle, Washington that are managed with organic practices. I then present the challenges and barriers to gardening in contaminated spaces. Finally, I make recommendations to address contamination in gardens spaces, and call for better regulatory standards and other forms of support to mitigate risk to users. (shrink)

Unless the public comes to agree that the benefits of food biotechnology are desirable and the associated risks are acceptable, our society may fail to realize much of the potential benefits. Three historical cases of major technological innovations whose benefits and risks were the subject of heated public controversy are examined, in search of lessons that may suggest a path toward consensus in the biotechnology debate. In each of the cases—water fluoridation, nuclear power and pesticides—proponents of the technology gathered scientific (...) evidence that they believed established that the innovations were safe. In each case, the federal government was heavily involved in oversight, safety regulation, and in the first two cases, active promotion of the technology. Supporters of the technologies employed a variety of communications strategies, ranging from massive “educational” campaigns (e.g. “Our Friend The Atom”) to vituperative ad hominem attacks on leading opponents. None of these strategies succeeded in achieving broad societal acceptance of the technologies. Fluoridation today is opposed as vigorously by activist groups as it was when first introduced around 1950; it has not been universally adopted even in the U.S., and it has been rejected in most other countries. The American nuclear power industry is moribund, and the public has essentially rejected the technology. The pesticide industry is thriving, with new generations of products succeeding older more hazardous chemicals in a constant cycle. However, strong regulation has failed to prevent adverse health and ecological effects, which have been empirically associated with pesticide uses after the chemicals were dispersed in the environment. Debate over whether risks of such effects are acceptable has been heated for four decades, with scientists and the public divided. None of these cases offers an ideal model for the biotechnology revolution, though they do reveal many strategies that have not worked. The biotechnology debate is also taking place at a time when our concepts of risk communication have improved, and when many consumers are more actively concerned with buying products perceived to be less likely to harm the environment. Based on the three case histories and more recent trends, some characteristics of a process for seeking a societal consensus are described. They include explicitly defining the subjects for consensus; including all stakeholders in a respectful dialogue; confronting value issues, such as acceptability of risks and ethical perceptions; listening to others’ perspectives, and being willing to change one’s own point of view. If activists on all sides of the food biotechnology debate are willing to commit to such a consensus-building process, there is hope that the U.S. national debate can be resolved in a manner satisfactory to essentially all parties.

In public debates, agricultural biotechnology is almost invariably discussed as a potential threat to the environment and to human health. Without downplaying the risks associated with this technology we emphasize that if properly regulated, it can be a forceful tool to solve environmental problems and promote human health. Agricultural biotechnology can reduce environmental problems in at least three ways: it can diminish the need for environmentally damaging agricultural practices such as pesticides, fertilizers, tillage, and irrigation. It can reduce the land (...) area needed for agriculture, thus reducing the CO2 effect of agriculture and improving biodiversity. It can produce energy in a CO2-neutral way (especially if new technologies involving the cultivation of microalgae become successful). Furthermore, agricultural biotechnology can have positive effects on human health by decreasing occupational and dietary exposure to pesticides, improving the nutritional value of food, and producing pharmaceuticals more efficiently. We argue that those who wish to give high priority to environmental goals cannot afford any longer to be mere onlookers while others decide the future directions of agricultural biotechnology.

The hazard of postharvest pest losses is ubiquitous in peasant farming systems; as a result, farmers invariably have some response to the threat of these losses. Responses to postharvest pests may be more extensive than to field pests, even when, by statistical measures, the usual levels of losses are comparable. In studies of pest management practices in three contrasting areas in Kenya, it was found that farmers virtually always rely on an array of techniques and strategies, usually including both older (...) and more modern practices. There is considerable variation among regions in the techniques used, due not only to climatic and socioeconomic factors, but also to variations in cultural history and preferences. The ways in which management practices have changed over time also vary by region. The major changes have been related to overall system change. Four main sources of change have been paramount: (1) population growth and the intensification of land use; (2) the introduction of new cash crops; (3) the introduction of new marketing infrastructure; and (4) the perception of increased environmental risk. Their effect on the replacement of older practices by newer ones is often interrelated. Traditional techniques are often based on materials derived from bushland, but increasing population density makes these difficult to continue as bushland and its common property resources disappear. Simultaneously, tolerance for losses is reduced as land availability is constrained. With the introduction of a cash crop infrastructure, new methods of pest management, especially pesticide use, become more readily available and may spread rapidly. Areas with good market infrastructure but varying population density may still differ considerably because with abundant land it is possible to compensate for expected losses by additional planting.A study of an FAO project to improve postharvest management through earlier harvesting and a redesigned storage crib indicate some reasons for its lack of widespread acceptance. Little or no attempt was made to adapt techniques to varying circumstances; instead, a single “solution” was meant to be applied across areas of vastly different conditions. In many cases, this project represented a radical response to a problem farmers considered they were coping with acceptably using existing methods. Although it probably represents an improvement over traditional storage methods in purely technical terms, the new technique also often involved major costs, readjustments, and cultural disruptions that may not have been anticipated by its designers. More likely to succeed would be a strategy that begins with some of farmers' existing practices and whose objective is to develop and offer a range of possible improvements from which farmers could select individual components appropriate to their conditions and needs.

Many U.S. corporations and the goods they produce negatively impact our society without breaking any laws. We are all too familiar with the tobacco industry's effect on public health and health care costs for smokers and nonsmokers, as well as the role of profit in the pharmaceutical industry's research priorities. It's Legal but It Ain't Right tackles these issues, plus the ethical ambiguities of legalized gambling, the firearms trade, the fast food industry, the pesticide industry, private security companies, and (...) more. Aiming to identify industries and goods that undermine our societal values and to hold them accountable for their actions, this collection makes a valuable contribution to the ongoing discussion of ethics in our time. This accessible exploration of corporate legitimacy and crime will be important reading for advocates, journalists, students, and anyone interested in the dichotomy between law and legitimacy.

Insecticide resistance management (IRM) programme was launched in 26 cotton-growing districts of India in 2002 to rationalize the use of pesticides. The IRM strategy is presented within a full Integrated Pest Management (IPM) context with the premise that unless full-fledged efforts to understand all aspects of resistance phenomenon are made, any attempt to implement IPM at field level would not bear results. Unlike earlier IPM programmes, this programme is directly implemented by the scientists of state agricultural universities; thus the information (...) flow is directly from research subsystem to farmers. The extension methodology is different from IPM-farmer field school model, but much the same information is provided in didactic form, through active participation of the farmers throughout the cotton-growing season, by deploying scouts in villages. The knowledge gain of the farmers covered under IRM programme was measured by employing before/after quasi-experimental research design. The overall knowledge gain was significant in terms of identification of insect pests and natural enemies of cotton crop, proper use of insecticides and timely sowing of the crop, but farmers did not reach the desired level of knowledge with respect to other cultural practices, which result in suppression of pest buildup. In the absence of any effective bio-agents, the level of IPM integration is limited to cultural practices, thresholds, agro ecosystem analysis and use of insecticides according to good agricultural practices.

In lieu of an abstract, here is a brief excerpt of the content:Ethics & the Environment 12.2 (2007) 128-130MuseSearchJournalsThis JournalContents[Access article in PDF]The Future of Environmental PhilosophyIrene J. KlaverEnvironmental philosophy is invitational: it in-vites thinking into life as well as life into thinking. Life is vita in Latin—the same vita as in vital and in vitamins. An in-vita-tion leads to new connections, or a renewal of existing relations. This affects how we understand things. As Wittgenstein says, "understanding [...] consists in (...) the very fact that we 'see connections.'"1 This is the case for philosophy in general, it makes connections, reveals relations between entities, thoughts, and events, which elucidates our understanding. Environmental philosophy has (re-)opened certain realms of relevance to philosophical inquiry by foregrounding our connections to the non-human world. It accommodates the broadest invitation: of life itself, including our relation to the conditions of life.The future of environmental philosophy lies precisely in this broad invitation. That means that it needs to occupy a profoundly interdisciplinary place, at the node of multiple institutions and practices. It deals with global issues on a local level and with the effects of local issues on a global scale. This involves science, policy, economy, law, ethics, aesthetics, religion, history, etc. An environmental philosopher is a specific generalist, someone who can connect various relations, sees the multiple angles in a particular perspective, the world in a grain of sand.The evolved environmental philosopher is a translator, translating various concerns along multiple perspectives. Translation is crucial to an understanding of the viewpoints, positions, and situations of others. Environmental philosophy enlarges the category of the "other" with many more entities. This is not a politically correct move to bring so-called repressed voices to the fore, it is to evoke different modes of knowledge and experience, to enhance cultural imagination2, a crucial component to raising awareness about environmental concerns.In her 1962 book Silent Spring3, Rachel Carson connected pesticide DDT to the decline in some predatory bird populations and sparked the rise of the environmental movement. She triggered a powerful cultural imagination by invoking a future silent spring without the singing of birds. Hegel saw the owl of Minerva as the symbol of wisdom, spreading "its wings only with the falling of the dusk."4 That is, for Hegel understanding arises after the events, philosophy can never be prescriptive. [End Page 128] Environmental philosophy, on the contrary, is engaged thinking, its understanding arises out of the practices of the everyday. The albatross around our neck is of our own shooting. Environmental ethics and environmental justice might stake out basic prescriptive rules, but these are always born from knowledge of—if not a participation in—certain practices. Environmental philosophy's bird is the spotted owl of social-political engagement, the canary in the mineshaft, but also the sparrow in the backyard. Birds that fly from dawn to dusk, seeing and reporting in the light the practical connections that reveal understanding, possible action, communication needs, and suggest a lexicon for translation. In and through practical connections rises therefore translation and understanding.Understanding is a transformative process—it changes our interpretative frameworks. When we see connections we begin to understand how the dead zone in the Gulf of Mexico is related to agriculture in the midwestern United States thousands of miles away, with watersheds within the Mississippi River Basin draining nitrogen fertilizers into the Mississippi, causing hypoxia in the Gulf.5 Environmental philosophy shows how wetlands are not just wastelands but take nitrogen and phosphorus out of the water, buffer "our" coasts, and feed the migrating birds along their long routes. By not seeing these connections, our wetlands are pumped dry; and by abusing our water, springs disappear, major rivers strand in sand, and dead zones emerge in oceans and seas. "These, too, were silent, deserted by all living things," Rachel Carson states, writing about streams.6 In the twenty first century it is no longer a "fable of tomorrow:" silent springs, silent rivers, silent seas.Environmental philosophy is empirical philosophy dealing with big issues such as global warming, biodiversity, and sustainability, but...

The controversy over genetically modified [GM] organisms is often framed in terms of possible hazards for human health. Articles in a previous volume of this *Encyclopedia* give a general overview of GM crops [@Mulvaney2014] and specifically examine human health [@Nordgard2014] and labeling [@Bruton2014] issues surrounding GM organisms. This article explores several other aspects of the controversy: environmental concerns, political and legal disputes, and the aim of "feeding the world" and promoting food security. Rather than discussing abstract, hypothetical GM organisms, this (...) article explores the consequences of the GM organisms that have actually been deployed in the particular contexts that they have been deployed, on the belief that there is little point in discussing GM organisms in an idealized or context-independent way.

Farmers are experts on their natural environment and are innate experimenters. However they do not know everything. Filling in gaps of missing farmer knowledge can help them improve their experiments. The authors designed and taught a course to Honduran farmers that effectively covered a number of key points on insect ecology and biology that farmers had not understood. After receiving the course many farmers did experiments to solve pest problems without synthetic pesticides.

Sodium monofluoroacetate (1080) is a mammalian pesticide used in different parts of the world for the control of mammalian pest species. In New Zealand it is used extensively and very successfully as a conservation management tool for the control of brushtail possums (Trichosurus vulpecula) – an introduced marsupial that has become a substantial agricultural and conservation management pest. Possums pose a threat to cattle farming in New Zealand as they are a vector for bovine tuberculosis. In protected natural areas, (...) possum browsing is responsible for large scale defoliation of native vegetation. As with many other pesticides, there has been some degree of popular concern about the use of this toxin and its safety, with particular reference to non-target effects. These concerns have been associated with potential non-target effects on human health, and the health of animals of recreational value (e.g., hunting dogs and game animals). This has led to the development of a strong “anti-1080” lobby in New Zealand. In contrast, this study encompasses a science-based risk analysis focusing on the potential risks to non-target native wildlife with a particular focus on chronic toxicity. It finds that there is evidence that 1080 may have endocrine disrupting capabilities (with potential relevance for non-target wildlife) but that this still needs more detailed investigation. This can be clarified by further targeted research. Further research is also needed to test the degradation rates of 1080 and its breakdown products at ecologically-relevant temperatures (i.e., winter stream temperatures – below 11 °C). Such research may demonstrate that some adjustment to 1080 risk management is warranted in New Zealand, or it may help to put to rest the current controversy over the use of this cost effective conservation management tool.

In lieu of an abstract, here is a brief excerpt of the content:Ethics & the Environment 7.2 (2002) 194-196 [Access article in PDF] The Body Toxic: An Environmental Memoir by Suzanne Antonetta. Washington, D.C.: Counterpoint, 2001. Pp. 242. Hardback $26; paper $15.00. ISBN 1-5824-3209-0. Memoirs rely on the power of recollection to reproduce the inward texture of experience. Autobiographies cast their authors as historians of the self, combing through documents and old letters, checking facts. In her first prose work, the (...) accomplished poet Suzanne Antonetta crosses the boundary between memoir and autobiography. Interweaving the rough textures of memory with slick surfaces of corporate data, she gives us a lyric meditation on the struggle to become undeceived. Recounting both the facts of corporate malfeasance and our fantastic capacity to filter our reality, she captures the relation between failures of understanding and failures of responsibility. She shows us how difficult it is to accept an unofficial truth. The Body Toxic is a thoughtful and obsessively readable contribution to environmental ethics.Antonetta tells us of childhood exposure to toxic wastes in a penurious and neglected corner of Barnegat Bay. She writes in retrospect, with painfully acquired knowledge of cancer clusters and disease-ridden families. [End Page 194] Her own body's malformed reproductive organs, riddled with tumors, prove spectacularly and tragically infertile when quadruplets spontaneously abort. Sharp backward glances at childhood pleasures; crabbing, berrying, and running through the sweet-smelling spray of DDT, twist us around. Children of the 1960s trail through pesticide as if the weekly truck brought some poisonous ice cream. The mosquitoes thrived: what happened to the children? We revisit these scenes obliquely. Denzer-Schaefer empties its effluent into the bay, cost-efficient Ciba-Geigy rids their chemical wastes through a pipe running straight into the woods, the local farm has become an illegal toxic dump for an unscrupulous contractor. Fire at a nearby nuclear weapons silo has hapless firemen spraying radioactive water into the air. The government responds: they build a chain link fence around the site. A nuclear power plant of the 'old-school' emanates levels of radioactivity to rival Chernobyl. The plant managers assiduously cover it up. This is not some national catalogue of Superfund sites: all take place within a dozen or so miles of a childhood summer house in New Jersey. These shards of a case study are scattered throughout Antonetta's non-linear narrative, piecing together experience, cause and effect.But this work is more ethically and artistically ambitious than the artificial clarity of case studies. Powerfully, Antonetta shows us the inner tangle of toxic mental life: the depression, listlessness, confusion, and self-medication of barely cognized symptoms. Self-clouding toxicity affects both the body and the mind. She fears that she and other family members are not right in the head. How far can she trust herself, and how far can she trace the causes? Is it heredity? Is it toxicity? Has toxic exposure potentiated some family trait? She reads out strings of hazardous chemicals like a rosary, overdetermining all of her symptoms. The distance between cause and effect shields the guilty. Strong toxicity undermines the ability of its victims to understand and act. The Body Toxic is part case study, part phenomenology of altered consciousness, and all too human. A course in environmental ethics could make imaginative use of its insights into a wide range of anthropocentric concerns. Antonetta considers questions of environmental justice, religious beliefs about the natural order, environmental responsibility and property rights, nuclear risk, and cost-benefit analysis in multi-dimensional form, an entry point for philosophical reflection. The Body Toxic is stimulating, controversial, and beautifully written.Many great works of literature signal their ethical intent by fostering a sense of identification with their subjects or protagonists. Antonetta's deft [End Page 195] blunt portraiture expands our moral sensibility by showing us how to be concerned for people with whom we are not meant to identify. The story begins before the beginning, with Antonetta's immigrant family. They are strangely familiar and not entirely sympathetic people, isolated between first generation immigrant cultures and fantasies of prosperous America, clinging to islands of... (shrink)

BIOS and BIFS are two California-based, small-scale alternative agricultural demonstration programs that define an applied Agriculture Partnership Model of extension. This model operates through a structure of local project leadership, a process of responsive farmer outreach and a primary goal of voluntary pesticide reduction. It reaches back to a Land Grant approach to extension of personal relationship, equal partnership, and collaborative learning. Overall findings from a systematic assessment of BIOS and BIFS imply that the operation and impacts of these (...) two Agriculture Partnership Projects owe more to the model, approach, and values of the projects than to any specific farming or extension techniques. A model of local partnership and responsive, learner-centered outreach, operational values such as flexibility and relationship, and a balanced systems approach to farm management and project operation combine to create a promising organizational response to the rapidly changing regulatory, environmental, and political circumstances confronting conventional farmers in California. Though some farm advisors and field research specialists within the University of California Cooperative Extension have successfully used the projects to leverage decreasing Extension resources, increase their one-on-one contact with farmers, and learn new outreach and agricultural skills, others within that system are highly critical of the two projects. Organizational tension between Cooperative Extension and the quasi-university Partnership Projects largely reflects differences in fundamental beliefs and values about legitimate knowledge, learning processes, and effective teaching as well as primary goals for agricultural outreach.

Brazil is the biggest market for pesticides in the world. In the registration process, a pesticide must be authorized by the Institute of the Environment, Health Surveillance Agency and Ministry of Agriculture. Evaluations follow a package of toxicological studies submitted by the companies and also based on the Brazilian law regarding pesticides. We confronted data produced by private laboratories, submitted to the Institute of the Environment for registration, with data obtained from scientific databases, corresponding to mutagenicity, carcinogenicity and teratogenicity (...) of pesticides. All studies submitted by the companies were carried out by private laboratories. From 247 pesticide formulations analyzed, none showed positive results for mutagenicity, carcinogenicity or teratogenicity. From 574 articles in the scientific literature, 84% published by public laboratories showed positive results, while 79% of those showing negative results came from private laboratories. There is an ethical concern about a conflict of interest between public/independent laboratories and private laboratories that produce data for registering pesticides. We demonstrated that there is a clear contradiction between public and private laboratories. Brazilian regulatory authorities have approved the registration of pesticides based almost exclusively on the monographs provided by the pesticide industry, because the use of scientific articles or information from the independent literature is strongly belittled by the industry. Pesticide companies argue that scientific articles cannot be trusted. Also, according to the industry, pesticide registration cannot be refused based on results from scientific articles. Thus, the registration of pesticides with mutagenic, carcinogenic and teratogenic risks has been approved in Brazil. (shrink)

Amidst broad debates about the “New Green Revolution” in Africa, input-intensive agriculture is on the rise in some parts of Africa. This paper examines the underlying drivers of the recent and rapid adoption of herbicides and genetically modified seeds in the Burkina Faso cotton sector. Drawing on 8 months of ethnographic fieldwork in the Houndé region, this article contends that economic and cultural dynamics—often considered separately in analyses of technology adoption—have co-produced a self-reinforcing technological treadmill. On the one hand, male (...) farmers seek to increase cotton production in response to an economic squeeze. At the same time, broader cultural shifts toward individualism have created labor shortages as a result of families splitting apart, parents putting their children in school, and some women and young men refusing to provide free labor. Male cotton farmers thus increase production by turning to labor-saving inputs like herbicides, but these inputs create more debt, further locking farmers into intensive production. This article thus expands on the classic concept of the technological treadmill, demonstrating how economic and cultural processes intersect within a process of agrarian change to drive labor-saving agricultural technology adoption in the Burkinabè cotton sector. This expanded treadmill concept illuminates the complex dynamics compelling farmers’ choices to opt into input-intensive agriculture, and also helps explain rising farmer differentiation, as poorer farmers struggle to stay afloat and wealthier farmers expand.

Neurodevelopmental disorders such as autism affect one-eighth of all U.S. newborns. Yet scientists, accessing the same data and using Bradford-Hill guidelines, draw different conclusions about the causes of these disorders. They disagree about the pesticide-harm hypothesis, that typical United States prenatal pesticide exposure can cause neurodevelopmental damage. This article aims to discover whether apparent scientific disagreement about this hypothesis might be partly attributable to questionable interpretations of the Bradford-Hill causal guidelines. Key scientists, who claim to employ Bradford-Hill causal (...) guidelines, yet fail to accept the pesticide-harm hypothesis, fall into errors of trimming the guidelines, requiring statistically-significant data, and ignoring semi-experimental evidence. However, the main scientists who accept the hypothesis appear to commit none of these errors. Although settling disagreement over the pesticide-harm hypothesis requires extensive analysis, this article suggests that at least some conflicts may arise because of questionable interpretations of the guidelines.
