This chapter explores the interrelationships between economic change and environmental issues, by showing how aspiration, education, and migration are variously connected to a loss of agroecological knowledges for rural young people. It reviews a series of case studies from Vietnam, India, and China on the implications for rural youth of changed aspirations and ecological and economic stress. The economic and cultural pressures of globalization mean young people increasingly aspire for a life outside of agrarian- and natural resource-based livelihoods.
In eastern Zambia, population growth has reduced per-capita land availability to such an extent that traditional bush fallows can no longer be practiced, and low soil fertility is a major constraint to crop production. Improved fallows (IF) based on leguminous trees are a low cash-input agroforestry practice to restore soil fertility. The objective of the study reported here was to assess the adoption of IF by farmers who tested the technology, including the extent to which the technology is practiced relative to its potential scale.
If agro-ecological systems are to realize their potential as sustainable alter- natives to conventional agricultural systems, innovation diffusion needs to be enhanced. We conducted surveys among 214 small-scale vegetable farmers in Benin, a food-deficit country in West Africa, on how they perceived the different attributes of eco-friendly nets (EFNs). The nets act as physical barriers against insects in vegetable production and so reduce pesticide use. Understanding farmer perceptions about new technologies helps reveal farmers’ propensity to adopt them.
Continually increasing food demand from a still–growing human population and the need for environmentally–friendly strategies for sustainable agricultural development require innovation and further enhancement of cropping systems’ factor productivity. The system of rice intensification (SRI) has been proposed as a suitable strategy to improve rice yields with reduced input requirements, most notably water and seed, while enhancing soil and water quality because agrochemical applications can be cut back.
In this paper, the authors review the conditions that have been undermining sustainable food and nutrition security in the Caribbean, focusing on issues of history, economy, and innovation. Building on this discussion, we then argue for a different approach to agricultural development in the Small Island Developing States of the CARICOM that draws primarily on socioecological resilience and agricultural innovation systems frameworks.

Esta presentación describe la experiencia evolutiva y los aprendizajes del Proyecto Innovaciones en cadenas de valor de Hortalizas especiales, Proyecto del MAP en la región del Trifinio
La investigación consistió en caracterizar las unidades productivas en función de su nivel de innovación o cambios que han realizado y su influencia con la pobreza, seguridad alimentaria familiar, nutrición de niños menores a 2.5 años y con la diversidad de ingresos de la familia. Se encontraron cuatro grupos de familia según su nivel de innovación, en donde las variables con mayor peso en la formación de los grupos fueron el número de cabras, número de especies vegetales para consumo humano, tamaño familiar y venta de mano de obra como fuente de ingresos.
El documento tiene como objetivo analizar los avances realizados por países de América Latina y el Caribe (ALC) en el fortalecimiento de la institucionalidad vinculada a la agricultura, el cambio climático y la seguridad alimentaria. El documento destaca iniciativas innovadoras, en ámbitos como la formulación de políticas, el desarrollo de marcos legales, el fomento de la investigación y la innovación, el desarrollo de mecanismos de financiamiento, y la gestión de riesgos climáticos, entre otros. La revisión está enfocada en las políticas nacionales
Esta presentación describe la experiencia y lecciones aprendidas en el proyecto de implementación de las Escuelas de Campo en la región de Trifino.
