Scarcity of fresh water, deteriorating water quality and soil salinity are the major growth limiting factors for agricultural productivity, food security and the sustainability of natural resources. “Salinization – the increasing amount of salt content in soil – contributes to land degradation, desertification and subsequently food insecurity. “Soil salinity is dynamic and spreading globally in over 100 countries and no continent is completely free from it. However, the countries posses semiarid to arid climate are facing severe salinization, and this is projected to increase due to climate change and its consequences: sea level rise and rising air temperature. The major challenges under these conditions are limited water availability with poor quality that is adversely affected by excessive salts in the soil. The availability of essential nutrients, especially nitrogen and potassium limiting under these conditions for the crops growing in these adverse soils are other main constraints for agricultural development of arid and semi-arid lands, making agricultural production difficult. This prevailing situation demands adaptation of genotypes physiologically and genetically more stable under stress conditions. Cereal crops mainly wheat and rice are the main food commodities for supporting food requirements. These crops are very sensitive towards these stresses and suffer from huge annual losses in their yield and put a great impact on our national economy.

An effective and economic technology for fruit retention in mango has been developed and introduced to mango growers at different locations of Sindh. This technology proved helpful in increasing mango productivity by 15-30%. This technology is being further extended to overcome flower/boll drop problem in chilies, tomatoes and cotton.
A number of woody species (Conocarpus lencifolious , Acacia stenophylla, Atriplex lentiformis, Leucaena leucocephala,
Acacia nilotica,Eucalyptus camaldulensis, Acacia ampliceps, Acacia machenochiena) suited for gainful utilization of highly salt affected lands has been identified which have the potential of giving economical yields (Rs.10000/ha.).
