Development Alternatives, founded in 1983, was one of the first major organisations set up specifically to address the problems of sustainable development. Its objectives are to attach the problems of poverty, resource degradation and population growth at the village level on a large, national scale in a self-financing manner. To achieve this, it has adopted the strategy of focussing sophisticated scientific, technological and management methods to the solution of simple everyday problems of survival and subsistence. Led by Ashok Khosla, the organisation has built up a major research centre which develops innovative technologies for basic human needs. Examples of such technologies include: low cost but high grade construction using local materials such as mud, fuel-efficient woodstoves for cooking, handmade recycled paper and high-productivity handloom weaving machines.
