BALWOIS (Water Observation and Information System for Balkan Countries) is a knowledge exchange and capacity-building network focused on water, climate, and the environment. Its platform supports the sharing of information and expertise among people and organizations working in these fields, with a particular focus on the Balkan region. The website provides access to network resources, including news, knowledge materials, and geographic information system content.

It also features conference information and proceedings, helping users explore contributions from relevant events. Visitors can register or sign in to participate in the platform, and the site includes country-based options that support access to its international community. Through these resources, BALWOIS brings together observation and information related to water systems while encouraging collaboration and capacity building across connected environmental topics.

Its services are presented as an online network and information hub rather than as commercial products, offering users a place to discover materials, follow updates, and engage with research and professional exchange concerning water, climate, and the environment
