production potential. Further statistics reveal that at least 200,000 to 300,000 hectares of irrigated area are lost every year because of soil salinization and waterlogging (Framji 1987). Currently, the planet Earth is losing 3 hectares of arable land a minute to the effects of salinization (Abrol et al. 1988). Oldeman et al. (1991) estimated that worldwide 10.5 million hectares are affected by waterlogging and 76.6 million hectares are affected by human- induced salinization. Dregne et al. (1991) estimated that about 43 million hectares of irrigated land in the world's dry area are affected by various processes of degradation, mainly waterlogging, salinization and alkalization. Barrow (1991), however, estimated that in the late 1980s roughly 30 to 46 million hectares were in a poor state due to salinization. According to a more recent survey by Ghassemi et al. (1995), 45.4 million hectares of irrigated areas and 31.2 million hectares of non-irrigated lands are salt-affected. This clearly shows that the estimates by different scholars, of the area affected by salinity and waterlogging vary widely. The problem of waterlogging and salinity seems to be more senous III developing countries. Maredia & Pingali (200 I) reported that India, China, Pakistan and the Central Asian countries are the most affected by salinity in the irrigated areas. The World BankilCID (1989) assumed that in developing countries, waterlogging and salinity are encountered at a signifIcant level in about 15 million hectares of irrigated land in the arid and semi-arid zones. Other estimates reveal that of the 92 million hectares of irrigated land in the developing countries, 45 million hectares require reclamation because of salinity and poor drainage (F AO 1979). Notwithstanding the reliability of various estimates on the adverse effects of irrigation on soil, there is a need to address this problem more systematically and scientitlcally4. Global estimates of the total area affected by salinity but still in production also vary considerably. In developed and developing countries together the problem of waterlogging and salinity account for a loss of about 1.1 million tonnes of grain output each year (Brown & Young 1990). EI-Ashry (1991), Rhoades (1987), and Kayasseh & Schenck (1989) estimate that salinity seriously affects productivity in 20 to 30 million ha of irrigated land. 4 For an extensive review of the scale of the salinity and waterlogging problems, see Wichelns (1999) and for a detailed discussion of the problems related to salinity and waterlogging, see Postel (1989) and Yudelman (1989). 8
~~~,~~ Figure 1.1 gives the data from II major irrigation countries which indicate that approximately 20 percent of irrigated land is affected by salinity. But the variation across countries in the share of irrigated land affected by salt is also large, ranging from 15 percent in China to 80 percent in Turkmenistan_ Figure 1_1: Extent of Salinity in some of the Major Countries China ~r I Values represent ;~t~tallrri~~~~~ 167_~ - Ind ia I 7 Iland affect~d by salt ip millign_5.( ... ~.~ ....._.. ~-..
