Which term describes the process of implementing land use practices and water management practices to protect and improve the quality of the water and other natural resources within a watershed by managing the use of those land and water resources in a comprehensive manner?

• A. Watershed management
• B. Integrated water resources planning
• C. Environmental zoning
• D. River restoration

Answer: (A)

Coordinating how land and water are used within a watershed to protect and improve water quality and other natural resources. A watershed is the area where all water drains to a common outlet, so activities like farming, development, forestry, and infrastructure inside that area directly influence runoff, erosion, nutrients, and pollutants that reach streams and groundwater. Watershed management brings land-use practices and water management together in a comprehensive, across-the-board way to safeguard water quality, habitat, and resources for people and ecosystems.

Integrated water resources planning is related but broader: it looks at the entire water system and multiple sectors beyond just the watershed context. Environmental zoning is a regulatory tool for land-use limits, not the full, integrated approach to managing land and water resources within a watershed. River restoration focuses on restoring a river’s physical form and ecology, which is only one part of broader watershed management.
