This book addresses an important topic of food security in South Asia with specific reference to climate change. Of the 1 billion food insecure people in the world, more than 30% are in South Asia. The problem of food insecurity may be exacerbated by the projected climate change especially because of the water scarcity caused by rapid melting of the glaciers in the Himalayas and increase in variability in monsoonal rains and frequency of extreme events. Furthermore, large populations of Bangladesh and other coastal regions may be displaced by sea level rise. Thus, this volume addresses recommended land use and soil/water/crop/vegetation management practices which would enable land managers to adapt to climate disruption by enhancing soil/ecosystem/social resilience. In addition to biophysical factors, this book also addresses the issues related to human dimensions including social, ethnical and political considerations.

In order to feed their burgeoning populations, developing nations will need to double cereal production by the year 2050. This increase will have to come from existing land, as little potential exists for bringing new land under cultivation -- a daunting prospect when one realizes that increased use and significantly higher concentrations of carbon dioxide have led to a severe depletion of the carbon pool in the world's soils. This is especially telling in developing countries where tropical climates further compromise the soil's ability to recover. In Climate Change and Global Food Se

Rapid urbanization started since early 1950s. Among numerous consequences of urbanization are change in landuse and land cover including deforestation, encroachment of prime farmland, and alterations in landscape. These consequences reduce the ecosystem carbon stocks especially in biota and soils, alter the hydrologic cycle by increasing runoff and decreasing soil water storage, change energy budget by altering albedo, and disrupt cycling of carbon and other elements. Such drastic alterations in land use and land cover and biogeochemical cycling of C and other elements affect global climate at local, regional and global scales because of drastic and irreversible changes in the structure, functions and dynamics of ecosystems. The global urban expansion rate is estimated at ~2 million ha (Mha) of additional land to accommodate annual population growth of 70 to 80 millions. Because urban areas consist of build up areas and green areas or free space, judicious management of free space is crucial to moderating the global carbon cycle. Open spaces can be sustainably managed for home lawns, sports grounds, recreational areas, forests, and urban agriculture. Green roofs are also important in influencing the albedo and the carbon and hydrologic cycles. The strategy is to increase the green space areas, enhance their net primary productivity, and increase the overall carbon budget of urban ecosystems. It is also important to link science with policy.
