Traditional models of household economic behavior have portrayed households as unified entities. They assume that household members agree about decisions and share resources in the most equitable way possible. More recently, however, economists have come to view households as domains of difference, where multiple decisionmakers may have different preferences and, in many cases, control separate sets of resources. This new approach has greatly improved understanding of household resource allocation behavior.

This chapter challenges one of the main tenets of agricultural economics—that households behave as though they are single individuals, with production factors allocated efficiently between men and women. In many contexts this is a convenient and innocuous assumption. It can be quite restrictive, however, when investigating the causes and welfare consequences of gender differences in agriculture.

The collective model of the household predicts that bargaining power determines the share of resources allocated to an individual within the household. The concept of bargaining power is elusive, however. It is perhaps useful at this point to outline the possible determinants of bargaining power, while not making any claims to measure power itself.

Most economic research treats the household as a single agent, assuming that individuals within the household share the same preferences or that there is a household “head” who has the final say. This simple framework has proved immensely useful; despite a common misperception, it can explain many differences in well-being or consumption patterns within households.

Economists who analyze household decisionmaking allocation have traditionally assumed that the household acts as a single unit. They assume that there exists one decisionmaker whose preferences form the basis of household welfare and that all household resources are effectively pooled. This approach is known as the “unitary model,” the “common preference model,” or the “joint family utility model,” depending on the study consulted.

"To end hunger and prevent the recurrence of famine and starvation, we need to take the following steps: invest in public health, child nutrition, education, women’s and girls’ social status, and other components of human capital; reform public institutions and create innovative funding and partnership arrangements; change government policies at all levels to be both pro-poor and pro-growth; increase funding for scientific and technological research to boost agricultural production and efficiency; and develop specific policies and institutions to deal with environmental degradation caused

Contrairement aux prévisions communément admises quant à l’aggravation du déclin économique de l’Afrique, une récente étude présente une vision alternative plus positive de l’avenir de ce continent. De nouveaux engagements politiques, une gestion du programme de développement sous égide africaine ainsi que l’accroissement de l’intérêt et des investissements dans les petites exploitations agricoles ont le potentiel d’arrêter, voire d’inverser la tendance spiroïdale de la famine, de la pauvreté, de la dégradation environnementale, des maladies et des guerres civiles.

This book synthesizes IFPRI's recent work on the role of gender in household decisionmaking in developing countries, provides evidence on how reducing gender gaps can contribute to improved food security, health, and nutrition in developing countries, and gives examples of interventions that actually work to reduce gender disparities. It is an accessible, easy-to-read synthesis of the gender research that IFPRI has undertaken in the 1990s.

Thailand has experienced rapid deforestation especially since the 1960s. While large areas of forestlands were designated as national forest reserves, many forests were actually converted into farmlands. This article focuses on the institutional and administrative aspects of the national forest reserve system, the core institution of forest conservation in Thailand, and examines the institutional structure, historical process mostly since the 1960s, and procedures of the national forest reserve system and related policies at both in national and local levels.

The Rocky Mountains of the western United States contain many economically important natural resources. Increasing development of these resources has lead to land degradation, which often requires restoration efforts. A common type of disturbance in this region is mineral extraction and these activities often occur in zones of vegetation dominated by shrubs. These mined lands have proven to be particularly challenging to restore to native shrub cover.

Agricultural management has its roots in the manipulation of the system to optimise conditions for crop production. It is now widely recognised that this could result in land degradation with subsequent serious impact on crop productivity if the nutrient losses to the agricultural system are not replaced. A nutrient budget is an account of gains and losses of nutrients in an agricultural system, a tool that could be used to develop sound nutrient management and sustainable agriculture.

Two well-known ancient sites in southern Anatolia were selected to investigate and quantify the impact of historical land degradation on the Mediterranean coast of Turkey. These sites are the Luwian settlements of Kelenderis (modern Aydıncık) and nearby Nagidos (Bozyazı), both in Mersin Province and both occupied since around 4000 BP. Changes in local climatic conditions over this period have produced variations in the rates of fluvial transport of sediment/soil from the hinterland into the relevant deltaic regions, thus influencing rates of coastal progradation and aggradation.
