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.

    Hasta finales de la década de los sesenta, los pobladores de la isla San Salvador, en Filipinas, gozaban del acceso libre e ilimitado a los recursos naturales costeros. A principios de los años setenta, una ola de inmigración, combinada con la integración de la economía de la isla al mercado internacional de peces ornamentales, y el cambio hacia las operaciones de pesca destructivas, arruinaron las zonas pesqueras y dieron lugar a los conflictos.

    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.
