High food prices are not only causing a humanitarian crisis, but also putting at risk the development potential of millions of people. Global agriculture markets are undergoing structural changes, and the next three to four years will pose great challenges for achieving an affordable and accessible food supply for the world's most vulnerable. Soaring food and fuel prices are creating a "perfect storm" for the world's most vulnerable.

"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.

"For the practice of agroforestry to yield its full potential, it needs to bring health and nutrition to the fore.

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.

Malaria, schistosomiasis (bilharzia), and Japanese encephalitis are the major vector-borne diseases whose increase or decrease can be attributed to agricultural water development (see table). Others include dengue fever, yellow fever, and filariasis. Young children in poor communities are particularly affected: malaria is among the top five causes of death among under-fives in Sub-Saharan Africa; schistosomiasis among children affects growth, nutritional status, and cognitive development; and encephalitis occurs mainly in young children...

Policymaking initiatives in agriculture and public health are often pursued in a parallel and unconnected fashion. Yet coherent, joint action in agriculture and health could have large potential benefits and substantially reduce risks for the poor. Among development professionals there is growing recognition that agriculture influences health, and health influences agriculture, and that both in turn have profound implications for poverty reduction.

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.

"Good health and productive agriculture are both essential in the fight against poverty. In a rapidly changing world, agriculture faces many challenges, both old (natural resource constraints, extreme weather conditions, and agricultural pests) and new (globalization, environmental degradation, problems of maintaining production in conflict situations). At the same time, new global health threats emerge, such as HIV/AIDS, SARS, and avian influenza, while old ones persist.

Las instituciones de acción colectiva y los sistemas de derechos de propiedad moldean la forma en que la gente usa los recursos naturales.A su vez, estos patrones de uso afectan los resultados de los sistemas de producción agrícola de la gente. Juntos, los mecanismos de acción colectiva y los sistemas de derechos de propiedad definen los incentivos a los que la gente accede por llevar a cabo estrategias de gestión sostenible y productiva, y afectan el nivel y distribución de los beneficios de los recursos naturales.

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.

This brief defines property rights and collective action and discusses the links to sustainability of natural resource management and agricultural systems and to poverty reduction, as well as the implications for policy and practice.
