Why are gender issues relevant for the environment? This section answers this question, highlighting the necessity for environmental policy and programmes to ensure that: interventions enhance and promote gender equality; women are fully involved in environmental decision-making processes; and the specific impacts of environmental degradation on women are tackled. In addition to explaining the relevance of gender to environmental policy and practice, the emergence of gender in mainstream environmental/development debates is detailed. Subsequently, a Gender, Environment and Development (GED) approach is discussed and its implications for policy and practice explored. Ten case studies illustrating the links between gender and the environment are provided, (eg. from India, Pakistan, the Dominican Republic, Mali, Burkino Faso, and Ecuador), as are links to other environment-related core texts (Gender and Energy, Gender, Trade and the Environment, and Gender and Environmental Management in Urban Areas), and relevant websites. The pivotal message is that it is imperative that the development community cultivates a better understanding of the linkages between gender and the environment if planning processes are to achieve both gender equality and environmental sustainability.
