The Department of Geography, Aligarh Muslim University, Aligarh, India, organised an international conference on the theme: Resource Development and Environmental Change-Emerging Issues and Challenges, during January 2009. The Conference was spread over 16 technical sessions and about 300 research papers were presented by eminent social scientists and researchers from within and outside India. This 3 vol. set puts together a selection of over 70 presentations of the event dealing with a very wide range of specific themes and research issues broadly related to areas such as environmental changes, management and development of natural resources, sustainable agriculture, economic development, food security, biodiversity, health and waste management, regional disparities, land utilisation and population dynamics. The learned authors have reflected upon their empirical research work in these areas and their research output holds high and policy oriented relevance for the developing countries and hence the publication has a strong reference value for the concerned scholars.
