In this brief, we explore the role that social institutions -specifically property rights and collective action - may play in the development of agroforestry.... In the future, property rights and collective action will play increasingly pivotal roles in defining rights and responsibilities over the externalities of tree management practices.

Agriculture produces food fundamental for human health. It therefore seems obvious that agriculture, food, and health are related! Agriculture affects whether people have enough food to eat, whether it is of sufficient nutritional value, and whether it is safe, all of which affect human health. But it is not so simple: history has taught that there are different ways of looking at the relationships between agriculture, food, and health. Agricultural connections to food and health are mediated by the natural environment, human culture, and technological change.

Agricultural growth will prove essential for improving the welfare of the vast majority of Africa’s poor. Roughly 80 percent of the continent’s poor live in rural areas, and even those who do not will depend heavily on increasing agricultural productivity to lift them out of poverty. Seventy percent of all Africans— and nearly 90 percent of the poor—work primarily in agriculture. As consumers, all of Africa’s poor—both urban and rural—count heavily on the efficiency of the continent’s farmers.

"Agriculture is the main source of livelihood of the majority of people affected by HIV and AIDS globally, and it is being progressively undermined by the disease. In Sub-Saharan Africa AIDS is affecting the rural landscape in ways that demand a rethinking of development policy and practice, and parts of South Asia may soon face a similar situation.... There is clearly tremendous scope for agricultural policy to become more HIV-responsive, both to further AIDS-related objectives and to help achieve agricultural objectives. Yet there are no magic bullets.

This case study explores the development, dissemination, adoption, and impact of improved tree fallows in rural western Kenya. The processes of technology development and dissemination throughout the region are described and analyzed. To analyze adoption and impact, the paper applies a variety of different data collection methods as well as samples from both pilot areas where researchers maintained a significant presence and non-pilot areas where farmers learned of the technologies through other channels.

La agrosilvicultura trata sobre los sistemas agrícolas integrados, en que los árboles juegan un papel prominente. La agrosilvicultura puede proporcionar una variedad de funciones o beneficios para los agricultores y las comunidades. Los más fáciles de identificar son los productos forestales utilizados por los humanos: leña para fuego, madera, vigas, frutas, medicinas y resinas. Un segundo grupo de beneficios consiste en los servicios que proporcionan los árboles a otras actividades agrícolas de los agricultores: abono vegetal, sombra, conservación de los suelos y estacas.

El documento hace una comparación de los cambios ocurridos en la propuesta Yasuni-ITT, entre los términos de referencia (versión 2009) y el acuerdo entre el PNUD y el gobierno ecuatoriano (versión 3 agosto 2010). El documento forma parte de la serie Análsis de coyuntura de Comité Ecuménico de Proyectos (CEP).

En el medio rural brasileño, las relaciones sociales, históricamente complejas, todavía esperan cambios fundamentales en la garantía de la democracia, la ciudadanía y la sostenibilidad del medio ambiente. Esta entrevista gira en torno al tema de la necesidad de cambiar las relaciones entre hombres y mujeres en el campo. No hay respuestas definitivas todavía, pero hay debate intenso que se extiende por todo el país.

Soil carbon is important for soil structure and related nutrient and water holding properties. Increasing soil carbon stocks results in improved crop growth and contributes to enhanced climate resilience. In addition, the increase in soil organic carbon through sustainable agricultural land management (SALM) practices, such as the use of cover crops, residue management and agroforestry, will also reduce the need for synthetic nitrogen fertiliser at a given level of crop production.

na necessidade de dar visibilidade a relações econômicas, ecológicas

A ideia de produzir este livro teve origem em um esforço compartilhado por organizações e redes vinculadas à Articulação Nacional de Agroecologia (ANA) de sistematizar evidências dos benefícios do enfoque agroecológico na gestão técnico-econômica da agricultura familiar, aqui apreendida em suas variadas formas de organização produtiva e expressão identitária.
