Proposed environmental solutions

Many different solutions to the problems have been suggested over the years, varying in feasibility and cost, including:

In January 1994, Kazakhstan, Uzbekistan, Turkmenistan, Tajikistan, and Kyrgyzstan signed a deal to pledge 1% of their budgets to help the sea recover.

In March 2000, UNESCO presented their "Water-related vision for the Aral Sea basin for the year 2025".

By 2006, the World Bank 's restoration projects, especially in the North Aral, were giving rise to some unexpected, tentative relief in what had been an extremely pessimistic picture.
