With a concerted and cooperative effort among the Aral Sea Basin States and the real help from Russia and the international community, there is hope to alleviate, at least partially, the most critical problems that beset the Aral Sea region. The key issues of health and medical improvement, providing an adequate supply of clean drinking water and implementation of measures to bring down population growth should be started immediately and could show major results within a decade. Reconstruction of irrigation systems to save water is also a priority, but will take decades to implement fully.

Efforts to preserve the delta of the Amu-Dar'ya are important because of its ecological and economic value. One proposal is to construct a low dike or dikes on the dried bottom in front of and around the delta to reflood former gulfs and raise ground water levels, partially restoring its former ecological character; improving agriculture, fisheries and trapping: and providing a barrier to salt, sand and dust blowing from the dried bottom of the Aral Sea.

Reducing the frequency and severity of salt and dust storms is also a priority. This could be accomplished by stabilization of the large expanses of saline former bottom along the northeastern and eastern shoreline of the sea which are the chief sources of such storms. The most feasible means for stabilization is planting of salt-tolerant vegetation (e.g. black saksaul) and application of chemicals to consolidate the loose surface material.

Partial restoration of the small sea is also feasible. Naturally separated from the large sea in 1987 its level could be raised with relatively small increases of inflow, compared to the situation for the large sea, since its surface area, and hence evaporation losses, are much smaller.

To restore the entire Aral Sea to its size would be a daunting task.

Practical consideration may dictate that even under the best of future circumstances, the Aral Sea can only partially be revived. Assuming the discharge to the sea were reasonably clean, endemic flora and fauna could be reintroduced to the sea from lakes in the Amu-Dar'ya and Syr-Dar'ya delta where they still survive (or from other lakes with similar ecological conditions to the pre1960s Aral Sea, such as Balkhash). They would probably do well in the freshened zones around the mouth of the Amu-Dar'ya and Syr-Dar'ya, even though the salinity in the open sea would be above the optimal for them. This is a powerful argument for making efforts to preserve what remains of the original flora and fauna of the Aral Sea, either in deltaic lakes or in parts of the remaining sea in which habitat conditions of the pre-recession Aral Sea could be artificially maintained. More salt-tolerant types of fishes could also be introduced, as long as care was taken to select species that would not become major competitors to the indigenous varieties.
