Climate, Society, and Sustainable Development: Assessing Vulnerability, Building Adaptive Capacity
Agriculture and food security, water resources, ecosystems, natural disasters, and human health are all affected significantly by short-term fluctuations of weather and by longer-term changes of climate. Such effects can be severe enough to disrupt national and regional economies, particularly in developing countries, thus exacerbating poverty and thwarting sustainable development in both the short and long term. Developed and developing countries differ in their vulnerability to the effects of climate and in their capacity to recover from them. Developing countries are expected to be more vulnerable than developed countries to long-term climate change caused by the anthropogenic build-up of greenhouse gases. The challenge is to integrate climate adaptability into sustainable development effectively, so that detrimental effects are minimized and positive effects are enhanced. In this chapter we address the questions of how climate generally and El Niño specifically can affect sustainable development, consider the related concepts of vulnerability and adaptive capacity, and evaluate policies and programs designed to incorporate improved responses to climate variability and change into society. Sustainable development, a term brought to the attention of the world by the Bruntland Report, Our Common Future (United Nations Commission on Environment and Development, 1987), is a broad, often normative term used to describe a process by which developing countries are able to achieve economic growth comparable to the more developed countries without compromising environmental health and social equity. The report defines development as sustainable when it meets the needs of the present without compromising the ability of future generations to meet their own needs. Another simpler working definition that has been put forward is “development that lasts” (Magalhães, 2000, p. 4). Sustainable development is often characterized asmultidimensional, having economic, social, environmental, and political aspects (Magalhães, 2000). Economic sustainability is defined as the ability of programs to exist without long-term government incentives. Social sustainability relates to progress toward amelioration of poverty, income equality, and inclusiveness; whereas political sustainability involves shared participation in decision making and in stable institutions. Environmental sustainability involves the use of natural resources in a way that preserves or enhances their productivity, even while conserving habitats, biodiversity, and landscape.
