Growth corridors are regions where natural resource-based industries, such as agriculture and mining, are being developed to boost economic growth. SUSTAIN (Sustainability and Inclusion Strategy for Growth Corridors), an IUCN-led initiative, aims to shape the investment and design of these corridors so that they are environmentally and socially sustainable.

Located in a vast floodplain, Tanzania’s Kilombero district hosts wetlands, waterfalls and iconic wildlife species, such as elephant, hippo, antelope and lion. The mountain rainforests are a vital water source  for the surrounding area and its economy. As part of SUSTAIN, the African Wildlife Foundation (AWF) is working with one of Tanzania’s biggest rice producers, valley farmers and mountain villages in Kilombero to increase agricultural productivity while conserving forests, water sources and wildlife at a coordinated landscape level. A pillar of the programme is a payment for ecosystems services (PES) scheme.
