The aim of this publication is to assist policymakers and development officials in enabling a more participatory role for women in women in development, sustainable development, and environmental management (WED), and to create awareness of the multisectoral and multidisciplinary linkages between WED. The introduction summarizes mandates from the Rio Declaration and Agenda 21, the Nairobi Forward Looking Strategies, and Principle 20 of the Rio Declaration on Strengthening Women's Role. The concept of development changed from the 1950s and 1960s focus on gross economic issues. By the 1970s, the focus shifted to the satisfaction of basic needs. Women's role in the development process was recognized at Mexico's 1975 UN Conference on Women and Development in the Women's Decade (1976-85), and the 1985 Conference in Nairobi. The links between WED are now acknowledged. The manual includes 4 modules. The first unit summarizes issues in Environmental Health (poverty, population pressure, resource use, food supply, energy, water and sanitation, urban services, settlements, and global environmental issues). The second unit's focus is on Women as Agents of Change (energy, agriculture, water, human settlements, forestry, transportation, and science and technology). The third module's focus is on women as managers of water and sanitation/waste. The fourth module's focus is on capacity building and guidelines for action at the program level.
