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.

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.

In the first part of this paper the role of the core principles in three different scenarios will be discussed. The first is a setting where a shared watercourse, but no specific treaty exists; the second, where a treaty is in the process of being negotiated; and the third where an agreement over the shared resource is in force. The second par t of the paper will look in detail at the normative content of each principle, its reflection in specific watercourse agreements and its implementation by joint bodies.

A sterilization control of paper impregnated with spores of the heat-resistant organism, Bacillus stearothermophilus, and specific culture media in a dehydrated state is described. When suspended in distilled water, the media will elute from the test strip and support the growth of surviving bacteria. The necessity of preparing media for culturing the controls is eliminated.

The ten years following the United Nations Conference on Environment and Development (Rio de Janeiro, 1992) have been years of intense activity in the reformation of national and international laws. Over the last decade, sustainable developmetn has become a universal watchword, and a major catalyst for the reorientation of legal texts. Profound legal changes have been triggered by the transformation of socialist economies and the accelerating globalization of trade and economy.

Han transcurrido 17 años desde la iniciación, en 1985, del conjunto de procesos nacionales de programación y ejecución de actividades forestales que contribuyen al desarrollo sostenible, conocido en un comienzo como los Planes de Acción Forestal Tropical (PAFT), y posteriormente, en 1992, con la revisión del marco inicial como los Programas de Acción Forestal Nacional (PAFN). Sucesivos esfuerzos para fortalecer esos procesos, superando sus iniciales deficiencias, dieron lugar a la estructuración de los programas forestales nacionales.

Duas posições opostas apresentam os trabalhadores agrícolas alentejanos ou como incapazes de participar em associações formais ou como “revolucionários naturais”. Partindo do caso de Baleizão, com particular referência à Reforma Agrária da década de 70, argumenta-se que ambas as perspectivas ignoram o pragmatismo associado a conjunturas específicas.
