A new “jurisdictional” approach to tropical deforestation and other dimensions of sustainable development is emerging. It builds on the important progress that is being made in achieving sustainable development farm-by-farm through supply chain interventions and public policies. It is “jurisdictional” because it applies to entire political geographies—states, provinces, districts, counties and nations. It features strong roles for regional governments, farm sectors, communities, civil society and the private sector in defining success, building incentive systems, and creating local pride in each region's progress towards sustainable development. This is the focus of Earth Innovation Institute’s new Jurisdictional Sustainability Primer released this week. Together with the Forests, Farms and Finance Initiative (3FI), Earth Innovation Institute convened two one-day workshops to build a shared understanding of jurisdictional sustainability and to answer some core questions—how do we define it? Why is it important? What are the elements of its success? And what are the pathways for achieving it? This document is fruit of a rich, collective effort involving input from 26 organizations and companies. It includes descriptions of three case studies of jurisdictional strategies that are in progress in Brazil (Mato Grosso and Acre States) and Indonesia (Central Kalimantan Province).
