Water disputes between states over shared rivers highlight the need for:

The correct answer is: a) Interstate water agreements.

Water disputes between states over shared rivers highlight the need for interstate water agreements. These agreements are essential to ensure that all states have a fair share of the water resources and that the rivers are managed in a sustainable way.

Judicial intervention may be necessary in some cases to resolve water disputes, but it is not a long-term solution. Building more dams is not always the best way to manage water resources, as it can have negative environmental impacts. Promoting water conservation is important, but it is not enough to address the challenges of water scarcity.

Interstate water agreements are the best way to manage water resources in a fair and sustainable way. These agreements can help to resolve disputes, prevent conflicts, and ensure that all states have access to the water they need.

Here are some additional details about each option:

• Option a: Interstate water agreements are legally binding agreements between two or more states that share a water resource. These agreements can help to resolve disputes, prevent conflicts, and ensure that all states have access to the water they need.
• Option b: Judicial intervention is the process of resolving a dispute through the courts. This can be a necessary step in some cases, but it is not a long-term solution.
• Option c: Building more dams is one way to manage water resources. However, dams can have negative environmental impacts, such as disrupting fish migration and altering river ecosystems.
• Option d: Promoting water conservation is important, but it is not enough to address the challenges of water scarcity. Water conservation can help to reduce demand, but it cannot create new water resources.
