The proposed initiative involves deployment of rainwater harvest technologies (RHT) at the household community levels as a measure of controlling upstream runoff (causing flooding) as well as providing alternative freshwater source for domestic and agricultural usage during drought episode.
1. Household Rainwater Harvest (HRH) – This is a technology-driven, smart solution of holding substantial amount of potential flood water (available as runoff) using HRH equipment and making it available as an alternative water source for dry season usage. The solution not only withholds potential flood water, it also makes water available for various usages at times of crucial need.
2. Community Rainwater Harvest (CRH) – It is a large-scale edition of the design solution with bigger storage and distribution capacity. It involves construction of rainwater harvest complex (RHC) in the outskirts of the community to meet multiple demands for irrigation, FADAMA etc.

Objectives and beneficiaries
The objectives are to increase adaptive capacity/resilience of rural communities with river watershed to cope with seasonal flooding and alternating drought episodes. To demonstrate with practical examples on how communities can improve cultural rainwater harvest practice to mitigate the impact of flooding and drought.
The beneficiaries are vulnerable groups in the rural communities located in the upstream watershed which include hard to reach communities, ethno-religious minorities, women and children dominant households, socio-economically disadvantage and physically challenged groups.
Strong points of the practice
The initiative leverages on the following strong points:
* It is ecologically friendly, no carbon emission is involved
* It is culturally relevant hence sustainability
* It is a cheaper means of water harnessing , hence self-sustaining
* It is community driven involving participatory learning and action (PLA) strategy
* The deployment can be scale up and expand to other communities using trained local manpower
* Alternative source of livelihood for the trained local manpower through earning from installation charges
* Earnings from commercial supply of harvested rainwater
Expected results and benefits for climate change adaptation and mitigation
* Installation of 7nos of 2000/5000 (litres) capacity HRH in upstream communities
* Retention/Storage of 20000 (litres) of potential flood water
* technical installation capacity for local manpower
* Reduction in flood risk and threat in the down stream
* Mitigation against drought impact for both domestic and agricultural usage
* benefits of extra earnings to trained local manpower
* potential for return on commercial investment
* 7 households to benefit from the initiative
* 20000 litres potential flood water retention capacity.
Replicability potential of the practice
The initiative is replicable to other households and communities, with trained local manpower and demonstrated pilot schemes deployed.
