Este libro tiene como propósito servir como texto guía para la formación en extensión agropecuaria de los profesionales de las Ciencias Agrarias de la Universidad de Antioquia y como material de referencia para todas las universidades del país que hacen parte de la Red Nacional de Extensión Rural (RENER), al igual que para los profesionales en servicio que quieren mejorar sus capacidades en extensión agropecuaria, en un nuevo escenario de construcción de paz que requiere ajustes en la preparación del talento humano para apoyar la implementación del recientemente creado servicio de
Agriculture faces an enormous global challenge of feeding nine billion people by 2050. This means a comprehensive intensification of agriculture is required. Ecological intensification is gaining momentum as a clearly defined vision for increasing agriculture productivity and sustainability. How ecological intensification could be tailored to benefit smallholder farming systems in sub-Saharan Africa (SSA) remains the major question. In this study, we develop pathways relying on ecological intensification technologies and suiting different farm types of smallholder agriculture.
With 20% of the world's population but just 7% of the arable land, China has invested heavily in crop biotechnology to increase agricultural productivity. We examine research on insect-resistant genetically engineered (IRGE) crops in China, including strategies to promote their sustainable use. IRGE cotton, rice, and corn lines have been developed and proven efficacious for controlling lepidopteran crop pests. Ecological impact studies have demonstrated conservation of natural enemies of crop pests and halo suppression of crop-pest populations on a local scale.
The challenge of food security in Nigeria hinges on several factors of which poor technical efficiency is key. Using a stochastic frontier framework, we estimated the technical efficiency of agricultural households in Nigeria and tested for the significance of mean technical efficiency of food-secure and food-insecure agricultural households. We further assessed the determinants of agricultural households’ inefficiencies within the stochastic frontier model and adopted a standard probit model to assess the determinants of households’ food security status.
This publication presents a coherent Collaborative Framework for Food Systems Transformation (the FS Framework) that recommends key activities across the food system for accelerating the transition to sustainable food systems. The FS Framework is primarily intended for national or local government departments that are responsible for establishing institutions and designing and implementing policies at the local or national level to develop food systems in line with national objectives and goals.
Establishing food security remains a global challenge; it is thus a specific objective of the United Nations Sustainable Development Goals for 2030. Successfully delivering productive and sustainable agricultural systems worldwide will form the foundations for overcoming this challenge. Smart agriculture is often perceived as one key enabler when considering the twin objectives of eliminating world hunger and undernourishment. The practical realization, deployment, and adoption of smart agricultural systems remain distant due to a confluence of technological, social, and economic factors.
The slow adoption of new agricultural technologies is an important factor in explaining persistent productivity deficits among smallholders in Sub-Saharan Africa (SSA). Farmers delay in particular the uptake of technology packages. Since knowledge constraints are an important barrier to adoption, effective extension approaches are key. In recent decades, extension systems in many SSA countries have moved towards decentralized “bottom-up” models involving farmers as active stakeholders.
The first section provides a brief overview of the key opportunities for rural women, and the key challenges that they face. The purpose of the section is to explain why it is important to address dimensions of gender equality in investments around food and nutrition security and agriculture. The second section guides the reader through the steps required to integrate gender dimensions into the design of an investment.
There was a need for change in agricultural development in Angola, and CDAIS has been appreciated. Results show positive outcomes in a number of areas, including the acceptance of the benefits of strengthening functional capacities across different levels. And, although it is still too early to see the full benefits of the approach, many involved said they would continue to apply it in their other activities. This story begins with views and experiences from rice growers and their partners, as an example of one of the three innovation niche partnerships in Angola.
Results in Ethiopia show positive outcomes from CDAIS activities, proving the benefits of integrating functional capacity strengthening across individual, partnership, organisational and national levels. Common to all these levels are
