TOPIC

Agricultural Biotechnology

IFPRI provides research-based policy solutions to sustainably reduce poverty and end hunger and malnutrition in developing countries. In support of this mission, IFPRI researchers evaluate emerging technologies and policy innovations and consider supportive policy frameworks that can enhance farmers’ access to the benefits of innovations. Among these are innovations in natural resource management, climate and energy policies, mechanization and digital tools, agricultural diversity, and property rights and collective action. IFPRI also has a long-running program on biotechnology applications and biosafety systems.

Since the development of the first biotech crop varieties, IFPRI has analyzed their costs, risks, and benefits for farmers and consumers in low- and middle-income countries (LMICs). Evidence to date, including that generated by IFPRI researchers, has identified important productivity, environmental, and socioeconomic benefits from agricultural biotechnology for numerous developing countries. Evidence has also identified costs and risks, which underscores the importance of credible and functional regulatory systems for oversight, risk assessment, and mitigation while enabling countries to benefit from biotechnology innovations. IFPRI views this evidence as indicating that, when appropriately regulated, biotechnology can play an important role in sustainably increasing agricultural productivity, which aids in the reduction of poverty, hunger, and malnutrition. Today, more than 70 countries around the world are producing or importing living modified organisms, including a significant number of LMICs, while others are considering authorizing cultivation or imports.

At the request of governments seeking to ratify the Cartagena Protocol on Biosafety to the Convention on Biological Diversity, adopted in January 2000, IFPRI has worked to build local institutional capacities in LMICs related to the analysis of benefits, costs, and risks of agricultural biotechnology and to the formulation and implementation of appropriate, evidence-based regulatory systems. IFPRI provides technical assistance to regulators and other governmental actors as they consider developing national regulations to ensure the safe handling, transport, and use of living modified organisms resulting from modern biotechnology. While IFPRI provides technical assistance to its partners as they consider policy and regulatory options, all determinations on biosafety policies are solely within the purview of national authorities in line with their sovereign rights and obligations to their citizens. Recognizing ongoing controversies around biotechnology, IFPRI consistently emphasizes an evidence-based approach that allows for inclusive discourse with a wide range of stakeholders.

How do policy environments influence technology adoption? Insights from Nigeria’s pod borer resistant (PBR) cowpea experience

Policymakers are increasingly considering the promise of modern biotechnology, including genetically modified organisms (GMOs) to help solve development problems in health, agriculture, and other fields (Zambrano et al., 2022). However, debates persist around health and environmental implications (National Academies of Sciences, 2016; Raman, 2017; Smyth et al., 2021). The regulation of GMOs varies globally, with some countries implementing outright bans or imposing stringent controls (Sarkar et al., 2021; Yali, 2022). A recent study examines the Nigerian policy environment for Pod Borer Resistant (PBR) cowpea, which has been genetically engineered to resist the legume pod borer (Maruca vitrata) [Mockshell et al., (unpublished)]. Legume pod borers significantly reduce cowpea yield and quality, with losses of up to 80% reported (Andam et al., 2024; Mockshell et al., 2024). This policy note summarizes the findings of the paper, providing insights to guide policy development around the adoption of biotech food crops in Nigeria and other countries in Africa South of the Sahara (SSA). The primary research question is: Is there an enabling policy environment for PBR cowpea and what factors contribute to it?

Assessing the development impacts of bio-innovations: The case of genetically modified maize and cassava in Tanzania

Assessing the development impacts of bio-innovations: The case of genetically modified maize and cassava in Tanzania

Tanzania’s agriculture is characterized by low productivity due to unpredictable rainfall and the prevalence of pests and diseases. Genetically modified (GM) maize offering protection against drought and insects are being developed. Likewise, GM varieties resistant to cassava brown streak disease were developed. Building on prior crop-based analyses, we use the Rural Investment and Policy Analysis (RIAPA) CGE model to assess the impacts of the adoption of those GM crops. GM maize and cassava have positive effects on the economy, the Agri-Food System (AFS), and poverty. Given its stronger linkages in the AFS, the effects of the GM maize are stronger, especially in higher adoption and high yield scenarios. Likewise, the effects on the poorest and rural households are greater. The high variation across scenarios, and the significant effect of the high adoption/high yield scenarios, suggests a high return to investments and policies that realize these adoption rates and yield potential.

Best practices for acceptability of GM crops field trials conclusions: Lessons for Africa

The ability to transfer information about the performance, safety, and environmental impacts of a genetically modified (GM) crop from confined field trials (CFTs) conducted in one location to another is increasingly gaining importance in biosafety regulatory assessment and decision-making. The CFT process can be expensive, time-consuming, and logistically challenging. Data transportability can help overcome these challenges by allowing the use of data obtained from CFTs conducted in one country to inform regulatory decision-making in another country. Applicability of transported CFT data would be particularly beneficial to the public sector product developers and small enterprises that develop innovative GM events but cannot afford to replicate redundant CFTs, as well as regulatory authorities seeking to improve the deployment of limited resources. This review investigates case studies where transported CFT data have successfully been applied in biosafety assessment and decision-making, with an outlook of how African countries could benefit from a similar approach.

Demand-side and supply-side factors for accelerating varietal turnover in smallholder soybean farms

Demand-side and supply-side factors for accelerating varietal turnover in smallholder soybean farms

The rapid growth of soybean cultivation in the world augurs well for achieving SDG2 of promoting sustainable agriculture, ending hunger, achieving food security, and improving nutrition. India started promoting soybean cultivation in the 1970s to combat dietary protein deficiencies and augment smallholders’ incomes. However, soybean yield remains low and plateaued at one ton per hectare for the past three decades. This paper leverages a large primary dataset and explores the speed of soybean varietal change by applying survival functions and analyzing determinants of varietal turnover time employing a dynamic framework and harnessing duration analysis. The results show that adopting leading soybean varieties has reached saturation and that policy intervention can have an immediate impact. The weighted average age of soybean varieties in farmers’ fields is relatively high at 16 years, implying a slower varietal change rate. The lack of improved varieties with desirable traits, poor information flow, and growers’ preference for traits beyond yield-hamper faster varietal substitution. Further, analysis indicates regional variations in driving the speed of varietal replacement. The findings have significant implications for spurring soybean yields through investments in varietal development, leveraging modern molecular methods for long juvenility and photo-insensitivity, disseminating information, and institutional changes enabling the private sector participation in crop breeding.

Sustainable food and farming: When public perceptions depart from science

Sustainable food and farming: When public perceptions depart from science

This chapter examines four important food production innovations that have been favored by scientists but opposed by influential swathes of the public: Green Revolution farming, industrial agriculture, the use of synthetic chemicals versus organic farming, and genetically engineered crops (GMOs). While three of the four innovations enjoy widespread use despite civil society opposition, GMOs do not. This chapter explains why: except for GMOs, public misgivings did not find political expression until after farmers had experienced the benefits from these innovations, making them impossible to take away. However, activists raised strong objections early with respect to GMOs, before the seeds were in wide use, and therefore most farmers never had a chance to enjoy and defend the benefits. Genome editing, a more recent crop science breakthrough, met early legal resistance in Europe, but broad popular resistance is unlikely to follow, so widespread deployment in farming is likely.

Opportunities for orphan crops: Expected economic benefits from biotechnology

Opportunities for orphan crops: Expected economic benefits from biotechnology

An enabling, evidence-based decision-making framework is critical to support agricultural biotechnology innovation, and to ensure farmers’ access to genetically modified (GM) crops, including orphan crop varieties. A key element, and often a challenge in the decision-making process, involves the balancing of identified potential risks with expected economic benefits from GM crops. The latter is particularly challenging in the case of orphan crops, for which solid economic data is scarce. To address this challenge, the International Food Policy Research Institute (IFPRI) in collaboration with local economists analyzed the expected economic benefits to farmers and consumers from the adoption of GM crops in 5 sub-Saharan African countries. This paper focuses on case studies involving insect-resistant cowpea in Nigeria and Ghana; disease-resistant cassava in Uganda and Tanzania; and disease-resistant banana in Uganda. Estimations from these case studies show substantial economic benefits to farmers and consumers from the timely adoption and planting in farmers’ fields of GM orphan crops. Our analysis also shows how the benefits would significantly be reduced by regulatory or other delays that affect the timely release of these crops. These findings underscore the importance of having an enabling policy environment and regulatory system—covering, among other elements, biosafety and food/feed safety assessment, and varietal release registration—that is efficient, predictable, and transparent to ensure that the projected economic benefits are delivered and realized in a timely manner.

Genome-edited crops for improved food security of smallholder farmers

Widespread enthusiasm about potential contributions of genome-edited crops to address climate change, food security, nutrition and health, environmental sustainability and diversification of agriculture is dampened by concerns about the associated risks. Analysis of the top seven risks of genome-edited crops finds that the scientific risks are comparable to those of accepted, past and current breeding methods, but failure to address regulatory, legal and trade framework, and the granting of social license, squanders the potential benefits.
