Why a Global International Waters Assessment (GIWA)?

Area of Science:

• Environmental science
• Water resource management
• Global environmental policy

Background:

• The necessity of a comprehensive global water assessment was initially questioned.
• The Global Environmental Facility (GEF) and UNEP established the Global International Waters Assessment (GIWA).

Purpose of the Study:

• To justify the importance and impact of the Global International Waters Assessment (GIWA).
• To highlight GIWA's unique global, holistic, and policy-oriented approach to water issues.
• To present GIWA's key achievements, including publications and a network of regional experts.

Main Methods:

• Applying a common methodology across all global hydrosphere regions.
• Conducting water-related assessments with a focus on policy implications.
• Integrating ecological and socioeconomic considerations in water studies.

Main Results:

• GIWA offers a unique global and holistic policy-oriented approach, unlike regional or issue-specific assessments.
• GIWA publications provide essential advice for the GEF and other decision-making bodies.
• A robust network of regional focal points and teams has been established.

Conclusions:

• GIWA's comprehensive approach is vital for addressing global water challenges.
• The initiative successfully integrates diverse water systems—marine, freshwater, and groundwater.
• GIWA's work supports informed environmental decision-making on a global scale.
