Gene-editing is a breakthrough technology for crop improvement that addresses many concerns associated with its predecessor and distinctly different technology, genetically modified crops. The commercial success of gene-editing technology depends on the public’s acceptance of its foods. This study used data from a national survey of United States c...

The effects of transgenic corn use and federal biofuel policies on state-level cropping patterns in the US Corn Belt region are investigated using state-level data from 2000 to 2019. During this time, producers moved away from diverse cropping patterns and toward simpler rotational practices. Empirical evidence indicates that the intensification of...

Compared to the EU, regulations on antibiotic-use in livestock are less stringent in the U.S. If consumers prefer non-antibiotic or minimal antibiotic-use meat, labeling different levels of antibiotic-use in the U.S. could have the potential to mitigate the development of antibiotic-resistant livestock. This study used a survey of 660 US consumers...

Precision agriculture technologies (PATs) are promoted as part of both economically efficient and environmentally sustainable agriculture practices. Available PATs are generally classified into two groups; namely, embodied-knowledge and information-intensive PATs. Adoption levels of embodied-knowledge PATs are high relative to information-intensive...

This study uses location-specific data to investigate the role of spatially mediated peer effects in farmers' adoption of conservation agriculture practices. The literature has shown that farmers trust other farmers and one way to increase conservation practice adoption is through identifying feasible conservation practices in neighboring fields. E...

India experienced a consumption puzzle since the 1970s, whereby households' calorie intakes declined over time, despite significant economic growth. This declining trend in calorie intake (consumption puzzle) was reversed for the first time in 2011-12. This is the first empirical study that investigates the relationship between refinements in data...

To improve the economic and environmental sustainability of agriculture , information is needed on how to target research, teaching, and outreach programs. However, conducting survey research in general, and with agricultural producers specifically, is increasingly challenging given issues such as declining response rates and limited resources. Whi...

The availability of a large number of probiotic products with and without various health-related claims create challenges for manufacturers and consumers alike. Although empirical studies that provide insights for manufacturers and regulators on the effect of health-related claims on consumers' willingness to pay (WTP) for probiotics are important...

Driven by factors such as an increased reliance on genetically modified crops, government policies, and market forces, the crop mix in South Dakota and elsewhere in the United States has become less diverse and moved toward the production of corn and soybeans as the most predominant cash crops over the past two decades. Coinciding with a reduced co...

Background: Despite the substantial increase in the number of probiotic products available in the U.S. during the last decade and the potential for millennials to be a large market for probiotics, there is a lack of understanding about millennials’ awareness, use, and preference for probiotics. In this study, we examine the relationship between the...

High population density in Bangladesh implies that agricultural productivity improvement is key to ensure food security. This raises the need for increased research and development investment in the agricultural sector. Although Bangladesh has enacted various seed policy reforms since 1990s to attract the private sector, the seed sector in Banglade...

This book is an exploration into ethical tensions that new technology creates, with a particular focus on agricultural biotechnology and genetically modified (GM) food. There are four main arenas where new technologies generally, and agricultural biotechnology in particular, create ethical tensions, fault lines and pressure points. These are: publi...

The study has empirically revealed that the widely discussed 'calorie-consumption puzzle' appears to have disappeared in the recent years and has established a positive marginal effect of income on dietary energy intake among Indian households. Nevertheless, nutritional effect of improvement in income varies across expenditure-classes, and rural an...

While farm-level empirical studies demonstrate the contribution of Bt technology in increasing crop productivity, there are still questions about its contribution to long-term growth in productivity at the macro-level. Our study examines major technological and seed policy breakthroughs relevant for the cotton crop, and reviews their impact on over...

The governments of Bangladesh and India have set impressive targets to expand hybrid rice cultivation as part of their national food security strategies for the next decade. Although hybrid rice offers significant yield improvements over varietal rice, adoption by farmers remains low and unstable. This paper analyzes the technical challenges, marke...

India is the regional leader in research and development (R&D) in agricultural biotechnology (agri-biotech) in South Asia. Commercialization of Bacillus thuringiensis (Bt) cottonthe first and only commercial genetically engineered (GE) crop in Indiain 2002 was preceded by illegal cultivation and diffusion of unapproved cultivars, raising serious qu...

The government of India has set a target of expanding the cultivation of hybrid rice to 25 % of the area occupied by the crop by 2015. Current growth trends suggest that this target will not be met, despite the potential contribution of hybrid rice to lagging growth in national rice yields, overall rice production, land-use reallocation and food se...

The rapid expansion of hybrid rice cultivation in China has contributed significantly to improving food security in the country since the 1980s. However, few other Asian countries have seen similar expansions in hybrid rice cultivation or the associated yield and output gains. This paper examines the technical challenges, market opportunities, and...

The growth of private investment in developing‐country agriculture, new advances in the biological sciences, and rapid integration of developing countries into the global trading system has heightened interest in the topic of seed market and intellectual property rights’ (IPRs) policies among public policy‐makers, corporate decision‐makers and othe...

Building on the evidence from the impact of hybrid technology on varietal diversity loss, this paper explores ex ante the possible effects of introduction of Bt eggplant on on-farm varietal diversity of eggplant. The public–private partnership involved in the development and introduction of Bt eggplant provides a great opportunity to develop locall...

Current and long-term impacts of over-use of pesticides among farmers on human health and the ecosystem as a whole are substantial, given that farmers spray their eggplant with deadly pesticides 27 times a season, right up to the time of harvest. The moratorium on commercialization of Bt eggplant was imposed on the basis of precautionary principles...

US wheat varieties are examined for differential disease resistance between public and private varieties, an issue for critics of plant intellectual property. Analysis using disease resistance rankings of wheat varieties from Kansas and Texas indicate that private varieties are as or more resistant. This finding was further confirmed with two years...

With the growth of private investment in developing-country agriculture, new advances in the biological sciences, and rapid integration of developing countries into the global trading system, intellectual property rights (IPRs) have become an important concern for policymakers, corporate decisionmakers, and many other players in the agricultural se...

Plant Intellectual Property (IP) has evolved only since the 1930s accelerating among developing countries only since the 1990s under a trade agreement. Today only a few developing countries have Plant Variety Protection (PVP), the most common form. The incentive theory is quite clear that plant IP ought to enhance private sector investment and supp...

Policy makers in both developed and developing countries have identified Geographical Indications (GIs) as a potential mechanism to assist primarily the agriculture sector in developing countries by reducing supply competition for traditional products while raising/standardizing the quality of those products. The perception seems to be that benefit...

The application of intellectual property rights (IP) in developing countries is and remains highly controversial, particularly as regards applications to food/agriculture, and pharmaceuticals, which have direct ramifications for large numbers of peoples. One dimension complicating a reasoned dialogue on the public benefits of IP, particularly when...

"The objective of this paper is to evaluate the effect of Plant Variety Protection (PVP) on the productive merit/yield increases of US seed varieties. As an example, we use wheat varieties, which are and have been available as both protected and unprotected under PVP from both the public and private sectors. We find evidence that PVP has contribute...
