"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...

Many decisions that affect the well-being of individuals are made within families or households. The processes by which resources are allocated among individuals and the outcomes of those processes are commonly referred to as “intrahousehold resource allocation.” Since the early 1990s a growing literature has paid increasing attention to the role that intrahousehold resource allocation plays in affecting the outcome of development policy (see Strauss and Thomas 1995; Behrman 1997; Haddad, Hoddinott, and Alderman 1997 for reviews).

The previous sections have highlighted the importance of assets as a determinant of bargaining power within marriage. Both formal and informal institutions underlie asset accumulation and provide the basis for property rights. When women face social and legal restrictions in acquiring certain forms of assets, such as land, they may resort to accumulating other “assets” and investing in other forms of capital.

The concept of social capital, well grounded in the sociological and anthropological literatures (for example, Coleman 1988), is increasingly being analyzed and used by economists and other development policy practitioners. The entry point for many economists is Robert Putnam’s research on Italian regional economic performance (Putnam 1993) and his subsequent work in the United States. For Putnam, “social capital refers to features of social organization such as networks, norms, and social trust that facilitate coordination and cooperation for mutual benefit” (Putnam 1995, 67).

Much has been written about the importance of gender issues in designing and implementing agricultural evelopment projects (Cloud 1983; Alderman et al. 1994; Quisumbing et al. 1998). Part of this literature has been motivated by the important role that women play in food production, particularly in Sub-Saharan Africa (Boserup 1970; Dixon 1982; Gladwin and Macmillan 1989), as well as in the management of natural resources (Meinzen-Dick et al. 1997).

Pervasive poverty and undernutrition persist in Bangladesh. About half the country’s 130 million people cannot afford an adequate diet. Poverty has kept generations of families from sending their children to school, and without education their children’s future will be a distressing echo of their own. Furthermore, from birth, children from poor families are often deprived of the basic nutritional building blocks that they need to learn easily. Consequently, the pathway out of poverty is restricted for children from poor families.

There is renewed interest in the intrahousehold allocation of welfare, particularly among economists studying poor countries where even slight differences in the allocation of household resources can have dramatic consequences on child and female nutrition, morbidity, and mortality (Haddad and Hoddinott 1994; Rose 1999; Dercon and Krishnan 2000). The evidence collected so far tends to demonstrate that the allocation of consumption and leisure among household members varies systematically with their relative contributions to household total income (Thomas 1990; Alderman et al.

Gender differences in health and nutrition have long been a subject of study in the intrahousehold allocation literature. Unlike consumption expenditures or farm production, measurements of health and nutritional outcomes are always at the individual level, and thus factors that underlie systematic differences in outcomes—such as age, gender, and position within the household—are more readily apparent.

It is a well-known fact that households in developing countries often undergo weather-related and other shocks that drastically affect incomes. A large and growing literature explores the effectiveness of response to these events. One strand of the literature addresses the strategies that households and governments use to protect against income shocks (Udry 1990; Fafchamps, Udry, and Czukas 1998; Kochar 1999). A second strand looks at the effectiveness of these strategies in reducing fluctuations in consumption.

Despite substantial economic liberalization since the early 1990s, nontraditional exports in Zambia have grown only moderately and agricultural performance overall has been disappointing. Though agriculture accounts for less than 20 percent of gross domestic product (GDP), it is the most important source of employment, especially for women. Interpretations of Zambia’s poor performance variously emphasize external factors, such as declining copper prices and vulnerability to weather shocks, and market imperfections.
