Environmental trust funds vary widely in structure depending on the ways funds are sourced, managed and distributed. Most funds are governed by a mix of government and NGO representatives. Small private initiatives at the community level - as indicated by examples from Nepal, Pakistan, the Philippines, and Uganda - are more likely to be cost-effective and innovative than government-run larger funds.
In most countries, domestic investment in environmental issues is increasing. Environment funds have also been established in many countries and have contributed to the prominent role that NGOs now play in environmental action.
