UNDP provides policy advice, helps develop policy guidance, collects and provides evidence on what works and what doesn't, and conducts research and analysis. This involves the review of legal and regulatory framework (e.g. policies promoting sustainable practices, land tenure, land use planning, fiscal policy instruments), the strengthening of legal enforcement, the provision of a package of market based tools and economic incentives to sustainable production through the payments for ecosystem services, REDD+, among others.
An example of a successful regulatory reform is in Paraguay. Paraguay suffered high levels of deforestation due to agricultural expansion into the Atlantic Forest. In 2004 a legal moratorium was introduced and deforestation rates dropped by over 50%, demonstrating the impact of legal reform on land use.
