| Because trace minerals are important not only for human nutrition, but for plant nutrition as well, plant breeding holds great promise for making a significant low-cost and sustainable contribution to reducing micronutrient deficiencies in humans, and may have important spinoff effects for increasing farm productivity in developing countries in an environmentally beneficial way. This paper describes ongoing plant breeding research that could increase the intake of bioavailable zinc from food staple crops among vulnerable populations in developing countries. The three most promising plant breeding strategies to achieve this goal are (1) increasing the concentration of zinc in the plant, (2) reducing the amount of phytic acid (a strong inhibitor of zinc... |

| Breeding for food-staple plant varieties that load high amounts of iron and zinc in their seeds holds great promise for making a significant, low-cost, and sustainable contribution to reducing iron and zinc deficiencies in humans in developing countries. This strategy also may well have important spinoff effects for increasing farm productivity in developing countries in an environmentally-beneficial way. Understanding how household incomes, food prices, and culturally-based preference patterns interact to drive food consumption and nutrient intake patterns can provide crucial background information for designing effective nutrition intervention programs. Research in both of these areas is being pursued under a five-year project organized by the... |

| Despite achieving a significant cost reduction over the past two decades, the absolute cost of food subsidies in Egypt is still high relative to the benefits received by the poor. There is scope for better targeting food subsidies, in particular those for rationed cooking oil and sugar, both because reforms in this area are perceived to be far less politically sensitive than adjusting subsidy policies for bread and wheat flour and because higher income groups presently receive a significant percentage of the benefits. Targeting the high-subsidy green ration cards to the poor and the low-subsidy red ration cards to the nonpoor will require identification of both poor and nonpoor households. An International Food Policy Research Institute (IFPRI) research... |

| Secondary crops are of increasing interest to policymakers and planners in developing countries because of a desire to diversify economic activities and because of their proven potential to raise farm incomes and rural employment. To assess this potential, basic information on the demand characteristics for these crops is required. But, given the large number of possible crops to be studied, policy analysts require an estimation procedure that is less data-intensive and time-intensive than standard econometric estimation procedures. In this paper, a relatively new, low-cost procedure, based on demand for food characteristics, is applied, illustrating its usefulness for analysis of demand for potatoes in Bangladesh and Pakistan. In Asia, the potato should... |

| For some time now researchers at IFPRI and else where have been studying how resources are allocated within house holds in developing countries and why it matters from a policy perspective. Many social and cultural factors, as well as economic considerations, influence house hold decisions about the allocation of time, income, assets, and other resources. The recently published IFPRI book, Intrahousehold Resource Allocation in Developing Countries: Models, Methods, and Policy, edited by Lawrence Haddad, John Hoddinott, and Harold Alderman, provides an excellent review of the key relationships and empirical evidence. Many studies have looked at the way resources are distributed to men, women, and especially to small children, but one age group within the... |

| Over the past several years IFPRI has undertaken research on the production, consumption, and nutrition effects of agricultural commercialization in The Gambia, Guatemala, Kenya, the Philippines, and Rwanda. While it is widely recognized that the commercialization of agriculture is essential to overall economic development, various rural population groups adapt differently to the process of commercialization, depending on the resources available to them, economic and social conditions, and government policies. Many households benefit in the form of higher incomes; others may suffer a decline in income. A particular concern of policymakers has been the effect of commercialization on nutrition. The purpose of these studies has been to analyze the process of... |

| A food demand system is proposed, based on demand for energy, variety, and tastes of foods. By specifying utility as an explicit function of these characteristics, the entire matrix of demand elasticities can be derived for n foods and one nonfood from prior specification of just four elasticities, while avoiding any assumption of separability between foods. This framework can explain why poorest groups often are most price-responsive, but also can account for highest price-responsiveness by middle income groups. The system is applied to published food consumption data for urban and rural populations in Pakistan. Elasticities are compared with those obtained in a published Pakistan study applying an almost ideal demand system (AIDS). |

| Micronutrient deficiencies are particularly severe in Bangladesh. Understanding how household income, food prices, parental education and nutritional knowledge, and culturally based customs and food preferences interact to determine food consumption patterns (particularly for nonstaple foods), and so micronutrient intake, can provide crucial information for designing policies and intervention programs to improve human nutrition. Within the typical dietary patterns of the Bangladeshi survey population, the key food group with respect to micronutrient consumption is vegetables, providing nearly 95 percent of vitamin A intake, 75 percent of vitamin C intake, and 25 percent of iron intake. Vegetables are the least expensive sources of all of these nutrients.... |
