Tenders are invited for Construction of Greenhouses and Tree Nurseries around the Volcanoes National Park. Location: Kigali Deadline: Friday, 29/05/2026 23:59 Background The International Gorilla Conservation Program (IGCP) is a coalition of three leading international conservation organizations (Conservation International, Fauna & Flora and WWF) which was formed with the mission to protect the mountain gorillas and their habitat in the Democratic Republic of Congo, Rwanda, and Uganda. The programme works in close partnership with the Protected Area Authorities of the three countries; Institute Congolais pour la Conservation de la Nature (ICCN) in Democratic Republic of Congo (DRC), Rwanda Development Board (RDB) in Rwanda and Uganda Wildlife Authority (UWA) in Uganda. International Gorilla Conservation Programme (IGCP) is implementing community projects to strengthen ecosystem-based adaptation and conservation efforts. These initiatives support park-edge communities around Volcanoes National Park (VNP) in Rwanda to enhance climate resilience, ecosystem protection and restoration, mitigate zoonotic disease, thus contribute to community wellbeing and sustainable mountain gorilla conservation. In this regard, IGCP hereby invites bids from eligible national, competent and reputable bidders who have Electronic Billing Machine, to submit their offers for this tender. This call for proposals (CFP) is open on equal terms to all qualified companies fulfilling the requirement and registered in Rwanda. Since the greenhouses and tree nurseries will be managed daily by community members around VNP and directly benefit them, the contractor will be required to work with IGCP-partner Community Based Organizations (CBOs) during the establishment process, whenever possible. This approach aims to strengthen local capacity, foster community ownership and ensure long-term project sustainability.
