Simiyu Climate Resilience Project in Tanzania – an impact evaluation
The Simiyu Climate Resilience project is cofinanced by the Green Climate Fund and promotes clean water supply, access to sanitation and climate-smart agriculture. The aim is to strengthen the resilience of the population in the Simiyu Region in northern Tanzania with respect to the impacts of climate change. But how can changes in the population be measured and analysed?
The Simiyu Climate Resilience Project supports the Tanzanian government in its aim to provide 90% of the rural population with enough water by 2025. Supply structures will be created in three components – water supply, sanitation, agriculture – which will also strengthen the resilience of the population towards the impacts of climate change. The largest component of the project is the construction of an approximately 100km-long water pipeline from Lake Victoria to the country’s interior. Connection to the supply system is intended to ensure year-round, reliable and safe access to clean water for all villages within a 24km corridor around the main pipeline.
Construction of the water supply system is scheduled to start sometime in 2022. The construction schedule enables the impact evaluation to methodically measure the impacts of the project on the population in the Simiyu Region in the coming years: The evaluation compares the water access of the households connected to the system within the corridor with that of the households outside the corridor. The latter cannot be connected to the pipeline. This makes it possible to determine the causal effect of the project on water access and people’s health. As part of the impact evaluation, it is also intended to analyse the change in the population’s water access during pipeline construction in order to generate interim results during project implementation.
