Farming secondary forests in Indonesia
Estimates of the area of swidden fallow secondary forest in Indonesia are inaccurate, partly because swidden agricultural practices giving rise to the secondary forest are heterogeneous. Throughout Indonesia, swidden agriculture is evolving into more intensive land use. A mixed secondary forest tree crop management appears to be the first stage towards a tree crop based production in Sumatra and Kalimantan. This changes the value of the forest/tree component of swidden agriculture, or the systems it evolves into.
Influencia del uso de la tierra con cultivos de cacao, chakras y bosque primario, sobre la diversidad, almacenamiento de carbono y productividad en la Reserva de la Biosfera Sumaco, Ecuador.
La investigación se realizó en la Reserva de la Biosfera Sumaco, en la provincia del Napo, Republica del Ecuador. Se estudiaron siete sistemas de uso de la tierra: Chakras con y sin sombra, cultivos de cacao propagados por semilla con y sin sombra, cacao injertado con y sin sombra y bosque primario. Se evaluaron tres variables de respuesta: diversidad arbórea y arbustiva, almacenamiento-acumulación de carbono (C) y productividad, en los diferentes sistemas de usos de la tierra.
Sistemas agro y silvopastoriles en El Limón, municipio de Paso de Ovejas, Veracruz, México
La caracterización de los sistemas agroforestales es una buena herramienta que en su momento proporciona elementos de análisis para la toma de decisiones en sistemas de uso del suelo. El objetivo de la investigación fue caracterizar los sistemas agroforestales de acuerdo a sus componentes (agrícola, forestal y pecuario) y al principal uso de las especies arbóreas en la comunidad El Limón, municipio de Paso de Ovejas, Veracruz.
Understanding the links between agriculture and health: Agriculture and nutrition linkages -- old lessons and new paradigms
Agriculture is fundamental to achieving nutrition goals: it produces the food, energy, and nutrients essential for human health and well-being. Gains in food production have played a key role in feeding growing and malnourished populations. Yet they have not translated into a hunger-free world nor prevented the development of further nutritional challenges. Micronutrient deficiencies (for example, of vitamin A, iron, iodine, and zinc) are now recognized as being even more limiting for human growth, development, health, and productivity than energy deficits.
Understanding the links between agriculture and health: Agrobiodiversity, nutrition, and health
"With half the world’s population living in cities and towns, many poor urban dwellers face problems gaining access to adequate supplies of nutritionally balanced food. For many urban populations, an important source of food is urban and peri-urban agriculture (UPA). Production and processing of crops—particularly horticultural crops—and livestock is frequently part of urban and peri-urban livelihood strategies, and the food produced forms a large part of informal sector economic activity.
Understanding the links between agriculture and health: Agrobiodiversity, nutrition, and health
"Agricultural production relies on environmental services to transform raw inputs into the nutritious and diverse food that humans rely on for survival. Although the practice of agriculture is essential for human health, careless and inappropriate agricultural practices can degrade and contaminate natural resources and in so doing, harm human health. Modified agricultural practices can help mitigate these problems.
Understanding the links between agriculture and health: Agriculture, malaria, and water-associated diseases
"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.
The impact of agroforestry-based soil fertility replenishment practices on the poor in Western Kenya
Western Kenya is one of the most densely populated areas in Africa. Farming there is characterized by low inputs and low crop productivity. Poverty is rampant in the region. Yet the potential for agriculture is considered good. In the study described here, researchers looked specifially at soil fertility replenishment (SFR) systems...Focused on two specific systems -- the tree-based "improved fallow" system and the biomass transfer system -- the study compared rates of adoption in poor and nonpoor communities and evaluated the extent to which their adoption reduced poverty.
