CHALLENGES AND THE WAY TO IMPROVE Theme 3: Water Harvesting PILOT AREA LOCATION The site is located in the Central Region of Uganda, Mubende District, Kiganda sub-county, Kinoni Parish, Lwenyange village. The site is 6 km off Kampala-Fort portal Road and 100 km off Kampala Kinoni site location relative to Mubende and Kampala cities and main roads (on the left); Valley tank and surrounding area (on the right) (Google Earth, 2017) Theme 3: Water Harvesting PILOT AREA OVERVIEW Kinoni basin elevation Statistics [m]: Great variability in land morphology • STATISTICS_MAXIMUM=1283 Undulating hills [5-15%] • STATISTICS_MEAN= 1214 Soil fertility good to moderate • STATISTICS_MINIMUM=1192 • STATISTICS_STDDEV=17.7 Annual (bimodal) rainfall [1100-1300] mm/y Big potential for Rainfall uncertainty is critical increasing agricultural Smallholder farmers dependSeasons on rainD1-fed R1 D2 productionR2 through Months D J F M A M J J A S O N agricultural production for their livelihoods IRWM Water Soil Soil Crop yields below the achievablesupply potentialIrrigation Rainfall Irrigation Rainfall (ASDSIP) mode moisture moisture Kinoni basin Slope Statistics [%]: • STATISTICS_MAXIMUM=17 • STATISTICS_MEAN=5.07 • STATISTICS_MINIMUM=0 • STATISTICS_STDDEV=3.12 Theme 3: Water Harvesting OBJECTIVES – PILOT RELATED Main objectives of the pilot 1. Providing different uses of water from the macro- catchment system 2. Increase crop productivity through a combination of in-field WH and SWC techniques and improved agronomic/forestry practices on collective pilot fields 3. Increase farmers’ skills trough field trainings and demonstrations and study visits 4. Supporting the development of WH (for agricultural use) sub-sector strategies and policies Theme 3: Water Harvesting PROJECT COMPONENTS – PILOT RELATED Irrigation : small gravity irrigation system for high value crops Security of the system Lessons learnt – study tour Field training and demonstrations Management and Maintenance Solar Energy : solar Crops : WH –SWC – pumping system (from improved agronomic the valley tank to the practices on rain- pilot plots) fed/irrigated pilot plots The three main sub-components of the pilot project in Uganda Theme 3: Water Harvesting MAIN FINDINGS IN FIGURES/FACTS .

Theme 3: Water Harvesting EXPERIENCES AND LESSONS LEARNED - Valley tank is a Community project - WH/SWC/CA/AF widely promoted in - ‘Local adaptation’ is necessary Kinoni (FFS) - GCCA due to the variability that exists - 3 farmers’ groups trained; well between farms and farming organized and ambitious community families importance of social networks - More effective extension and local institutions to invest and service to deliver technologies ‘risk’ (innovate) more to the farmers - Local NGO C-CARE Uganda important - Good agro-dealer private sector contact on the ground (training + that ensures efficient fertilizer follow up) and seed availability and - Good decentralized technical services distribution of MAAIF (district level) - The (tank) water user committee created with extracted members from the three farmers groups mitigate the risk of conflicts (pastoralists and farmers) Theme 3: Water Harvesting CHALLENGES AND THE WAY TO IMPROVE CHALLENGES SCOPE FOR IMPROVEMENT - Security of the tank, irrigation system and - An agreement among the community is pilots / Prevention of conflicts needed / Involve all farmers’ groups - Competition for mulch and fodder - Training to farmers on crop residues management + increase production of improved fodder + grass/shrubs through vegetated SWC structures - Increasing of soil fertility - Training on improved compost management/ISFM + agroforestry (Nitrogen fixing species) - Water availability for multiple uses - Prevention of siltation - Improve water management around the - Extra resources in terms of labour and tank and ensure daily maintenance + organic materials - Participation of the community + cash for work Theme 3: Water Harvesting THANK YOU FOR YOUR ATTENTION .
