South Asia is one of the major rice producing regions of the world, with about 50 million ha under its cultivation. Much of this area has a single crop per year; usually rainy season rice and no crop is grown after the rains. The Indo-Gangetic Plain (IGP) alone in South Asia occupies about 8 million ha under rice during the rainy season. Approximately, 2.5 million ha of rainfed rice land in IGP is left fallow. The large and growing population of the region especially in the IGP requires ever-increasing quantities of locally available food grains. The large land areas that lie fallow with adequate moisture to grow a second crop for much of the year are particular cause of concern in IGP. Subbarao et al. (2001) estimated 14 million ha rice fallow lands in South Asia (Bangladesh, Nepal, Pakistan and India). However, these studies may under-represent the true total, because it failed to identify any rice fallow lands in Ballia district of Uttar Pradesh in India, and the current study identified nearly 17,000 ha of rice fallows in the same district. If this figure were to be added, the total area would stand at 36,904 ha (Fig. 1).
