Agricultural extension services: From transfer of technology to facilitation for innovation

Agricultural extension services: From transfer of technology to facilitation for innovation

Agricultural extension and rural advisory services play a key role in the agrifood systems of many low- and middle-income countries by supporting farmers’ efforts to enhance productivity, strengthen resilience to shocks, and conserve the natural resource base on which these systems depend. This chapter applies IFPRI’s “best fit” conceptual framework to examine the global evolution of agricultural extension and rural advisory services over the past 50 years, as well as the shift from a “transfer of technology” approach to a more sophisticated “facilitation for innovation” paradigm.

Using best-worst scaling to inform agroecological interventions in Western Kenya

Using best-worst scaling to inform agroecological interventions in Western Kenya

Both the demand for food and the environmental impacts of food production are estimated to significantly increase by 2050. Agroecological interventions have proven effective in facilitating the transition from current food production systems to more sustainable ones. These interventions can not only ensure more equitable food and nutritional security but also address poverty and reduce environmental impacts. As such, agroecological interventions can generate both private and public ecosystem services. Farmers play a key role in how food is produced, as the practices they use are linked with their preferences and expertise, as well as the constraints they face. Understanding farmers’ preferences for the adoption of different agroecological practices and their perceptions of the associated costs and benefits is critical to informing policies that can effectively support farmers in transitioning to more sustainable practices, including those that contribute to the generation of ecosystem services highly valued by broader society. To assess such preferences, we conducted a survey among farmers in Western Kenya which included a best-worst scaling experiment augmented by qualitative questions about the reasons for farmers’ views about the importance of the benefits arising from agroecological practices. Results show that farmers have strong preferences for adopting agroecological practices that generate private goods and are directly related to increasing productivity and food security, including improving health of household members. These may also include practices that have some public good elements as well, such as increasing agrobiodiversity. However, practices that generate broader public good benefits, including improved forest quality/coverage, reduced off-farm environmental impacts, greater community-level resilience to shocks, and improved landscape and wildlife management, were less important to farmers. Such findings can be used to inform policies that support farmer adoption of agroecological interventions best suited to different farming communities, as well as indicating the need for additional types of market-based incentives, such as through Payments for Ecosystem Service mechanisms.

Nature-Positive Solutions Initiative survey report: Colombia

Nature-Positive Solutions Initiative survey report: Colombia

This study is part of the CGIAR Research Initiative on Nature-Positive Solutions for shifting agrifood systems to more resilient and sustainable pathways” (NATURE+), which aims to promote sustainable agricultural productivity through nature-positive solutions (NPS) by addressing three critical challenges: Land Degradation: Industrial agriculture, while ensuring large-scale food production, has caused severe environmental harm, including 80% of global deforestation, threats to 86% of endangered species, significant biodiversity loss, and up to 37% of global greenhouse gas emissions. It also depletes water and soil health, reducing crop resilience and lowering farming incomes and nutrition outcomes. To mitigate these impacts, a shift toward resilient farming systems that support smallholder farmers and enhance agriculture’s role as a positive force for nature is essential. Limited Evidence and Knowledge to Support NPS: Awareness of the environmental costs of industrial agriculture has highlighted the need for sustainable farming practices, especially after the 2021 UN Food System Summit and the COVID-19 pandemic. NPS has significant potential, including creating 395 million jobs by 2030 (as per the 2020 World Economic Forum). However, gaps in evidence and tools for decision-making hinder scaling efforts. Research in biodiversity, soil health, and waste management is crucial to develop scalable innovations and support agricultural research for community development. Lack of Business Models for Public-Private Partnerships: The private sector plays a vital role in scaling impact oriented solutions, requiring supportive policies and incentives to encourage investments in sustainable pathways. Developing business models that combine scientific innovation with ecological, social, and livelihood benefits is necessary to foster collaboration and drive smallholder farming toward nature-positive practices.
