The Western Balkan region, also known as the Balkans, encompasses several Southeast European countries, including Albania, Bosnia and Herzegovina, Croatia, Kosovo, Montenegro, North Macedonia, and Serbia

Climate change is a critical challenge of modern society, affecting the natural and built environment on an unprecedented scale.

Water, energy, food, and ecosystems (WEFE) are at the heart of long-term social and economic stability. However, integrated management of water, energy, and land resources remain a great challenge in the Western Balkans.

Renewable energy sources are the oldest, more reliable, and environmentally friendly. Particularly, hydropower remains the most valuable energy source. The estimated potential of renewable energy sources is enormous.
