UNDP works to eradicate poverty, reduce inequalities, and protect the planet through the sustainable development of nations, in more than 170 countries and territories. We help countries develop strong policies, skills, partnerships and institutions so they can sustain their progress. In Zimbabwe, UNDP is working for a Zimbabwe that is empowered and more resilient to create and sustain growth that will improve people’s lives. We focus on areas that have a multiplier effect through a targeted build-up of capacities, policies, the creation of dialogue space, and scalable downstream interventions.
UNDP Zimbabwe is working with the Foreign Commonwealth and Development Office (FCDO) in Zimbabwe to support the government of Zimbabwe attain its climate goals through the Climate Adaptation Water and Energy Programme (CAWEP).The CAWEP programme aims to support vulnerable communities and institutions’ adaptation and resilience capacity to climate shocks. Through this programme UNDP and FCDO is supporting the development of climate resilient, multiple use water and renewable energy infrastructure in vulnerable communities of Zimbabwe to enable;
- continued access to water for productive and household use, including during droughts and floods;
- improved access to clean and affordable energy to support economic activities with the intention of supporting more sustainable livelihoods’ outcomes.The project will align and contribute towards the Government of Zimbabwe's (GoZ) climate change priorities outlined in various strategies, such as its National Development Strategy, Nationally Determined Contributions, National Climate Change Policy.
Against this background, the project seeks to engage the services of one(1) consulting irrigation engineering consultant with adequate experience and working knowledge in climate proofed irrigation systems studies and designs, to act as a consultant for detailed techno-social feasibility studies, preparation of detailed designs including system layouts, pump stations, renewable energy power options and develop bill of quantities for the 2 irrigations schemes. The task will contribute to the development of climate resilient land and water management systems for smallholder households in irrigated lands.
