Who we are


IDIS is an environmental non-government organization dedicated to the protection and preservation of Davao’s watersheds.

It has been  registered as a non-profit organization with the Securities and Exchanges Commission (SEC)  since March 29,1999.

IDIS opposes the intensive pesticide use in  monocrop agribusinesses since it pollutes and destroys water resources, the health of people and the environment.

IDIS  supports sustainable ecological farming and is committed to empowering people in defense of their right to a life in a clean and healthy environment.

Our Beginnings

The founders of Interface Development Interventions believed that no one player can bring development alone, hence the importance of “interfacing” with various sectors whether POs, NGOs, or government.

Interface may refer to the interconnections between systems or human beings or a thing or circumstance that enables separate or sometimes incompatible elements to coordinate effectively. Interfacing means bringing together, connecting or synchronizing.

For eighteen years, IDIS has done just that, establishing itself as the crucial link for interface to happen among various stakeholders to realize the vision and mission of clean water and healthy watersheds for Davao city.

From the start, the founders decided they would not establish a people’s organization but instead will work with the existing organizations in the community including cooperatives, women’s groups, and the church. They want to work with them in an integrated area development, replicating the integrated NGO network in Antique where our founders were from.

They developed a framework with 8 key result areas which  included culture, environment, gender and agriculture for interfacing of players in Baguio district. But one thing soon became apparent. Baguio was a great rural district, people had their farms but the plantations were expanding. It became clear that the environmental issue was becoming alarming and a lot of action was needed to address it. And that set the pace for the start of IDIS’ advocacy work, with th campaign for the banning of aerial spraying in banana plantations.
