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.

"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.

Much empirical work has approached the problem of how resource allocations are made within households from the perspective that if preferences differ, welfare outcomes depend on the power of individuals to exert their own preferences. Measures of power are therefore a central component of quantitative empirical approaches to understanding how different preferences translate into different welfare outcomes. Following most of the empirical studies in this genre, this chapter focuses on dynamics within couples.

Among financial institutions serving poor households around the world, microfinance programs have emerged as important players. These programs typically make small loans—sometimes as small as US$50 to US$100 and sometimes as large as several thousand dollars-to households lacking access to formal-sector banks (see, for example, Lapenu and Zeller 2001). One important achievement of the microfinance movement has been its relative success in deliberately reaching out to poor women living in diverse socioeconomic environments.

Since 1997 Mexico has provided poor families with cash benefits linked to children’s school attendance and regular clinic attendance, as well as in-kind health benefits and nutritional supplements, through the Programa Nacional de Educación, Salud y Alimentación (PROGRESA). Unlike previous social programs in Mexico, this nationwide antipoverty program targets transfers to the mother of the family.
