Out of total world crop land of 1500 m ha, 1110 m ha is rain fed while only 390 m ha is irrigated. It has been reported that the globally human-induced salinisation is to an extent of 76.6 million ha (21.2 m ha strong, 20.8 m ha moderate and 34.6 m ha slightly salinized). This area is distributed with 52.7 m ha in Asia (69%), 14.8 m ha in Africa (19%) and 3.8 m ha in Europe (5%). A total of 31.2 m ha can be attributed to secondary salinisation of non-irrigated and 45.4 m ha in irrigated areas (Table 1). In terms of percent of the irrigated land, the area varies from 9% to about 34%. As per the above estimate nearly 67.5 % of the water logged salt affected lands are in Asia and Africa impacting the food grains production to a large extent. Not Available |
