4 I. Catchment characteristics Overlap between districts and catchment Ngororero 10% Nyabihu 10% Rubavu 40% Rutsiro 40%

5 Catchment Characteristics (Cont ) A-level 2 catchment, and is part of the larger level 1 Lake Kivu Catchment Total Surface Area: sqkm Characterized by high rainfall (1200mm/year and above) and a relatively short dry season Population: 74% rural, 26% urban; population: 248,916 (47.9 male & 52.1 female)

6 Gishwati Mukura National Park (SEB Upstream & Pfunda) Tea Plantations (Pfunda subcatchment) Key features Cattle ranching (Karambo and Bihongora subcatchment) Hydropowers (Gisenyi, Pfunda & Keya) & Gihira WTP (SEB Downstream)

7 Sebeya outlet

8 II. Key issues and opportunities Issues Mining exploitation increasing siltation to rivers Soil erosion (including riverbank erosion by agriculture & cattle) Sedimentation is a major impediment to the efficiency and sustainability of downstream hydropowers (Gisenyi, Pfunda & Keya) & Gihira WTP Flooding (Mahoko town center, Nyundo Catholic school ) Opportunities Abundant water Tourism/Gishwati National Park Forest Rubavu ranked among secondary cities/vicinity of Goma town/drc Modern grazing area Mineral resources Fertile soils

9 Issues (Cont ) Complex topography of the catchment induces peak discharges with high energies during extreme rainfall events at the outlet of the catchment which results in damaging the Tam-Tam bridge

10 Mining exploitation

11 Sand extraction from Sebeya river/buffer zone destruction

12 Flooding issue Ref Flood study Page 15 Nyundo catholic school «petit séminaire» severely damaged by floods

13 Erosion downstream the tam-tam bridge/downstream wing walls broken due i.e. scouring of their foundations

14 III. Drivers for Economic Development Sub catchment Economic drivers Sebeya Upstream Tourism/Gishwati National Park + cattle ranching + dairy-meat value chain Mining, Forestry, Small scale agriculture Districts Rutsiro, Ngororero, Rubavu Sebeya Downstream Urbanization, vicinity of Goma - DRCongo Tourism (Rubavu town, Kivu lake) Sand mining, quarries Rubavu Karambo Bihongora Pfunda Horticulture \Cattle ranching Forestry Mining Cattle ranching Forestry, Mining Tea factory, estate and outgrowers Tourism Gishwati National Park Nyabihu, Rubavu All 4 districts Rutsiro

15 IV. Ongoing implementation One Early Implementation Project (EIP) is being implemented in Rubavu and Rutsiro districts, Kanama and Nyabirasi sectors respectively Components: Agroforestry, Terraces, river buffer zone protection, forestation & Gullies rehabilitation. Total Surface Area: ha % of progress: (of January 2018)

16 EIP terracing in Kanama sector

17 V.IWRM Packages 1. Landscape Restoration for livelihood improvement, tourism, and cattle ranching value chains development in Sebeya Upstream Sub-catchment 2. Integrated sediment & flood management for Sebeya downstream and Karambo sub-catchments Taming the Sebeya river

18 Location of IWRM Packages Karambo/ Downstream Package SEB Upstream Package

19 Package #1: SEBEYA UPSTREAM Integrated Water Management Package

20 Components Landscape restoration and protection, and water harvesting (terracing, agroforestry, forest plantation, river buffer zones protection; water storage, climate smart agriculture practices, Pilot for IES to reduce dependence on biomass fuels, Capacity building ) Protection of water abstraction areas for livestock & community water supply (complementing the Dairy project of IFAD)

21 Package # 2: Integrated sediment & flood management for Sebeya downstream and Karambo Sub-catchments Taming the Sebeya river

22 Components Landscape restoration and river bank protection, and water harvesting (Terracing, agroforestry, River buffer zone protection, reforestation, gully rehabilitationclimate smart agriculture practices, water storage, IES. River training works, flood and landslides mitigation (Design of adequate protection of Gisunyu bridge, and protecting river banks at the confluence between Gisunyu and Karambo rivers; River training; Building Mahoko trade centre diversion channel; Propose adequate solutions for sand mining activities: location and infrastructure

23 Cross cutting themes Capacity building Community and support to women and men via the Farmer Field Schools Climate smart agriculture

24 VI. Way forward DDS Alignment Feasibility Study and Details Designs for approved IWRM Packages Approval of projects and implementation Coordination/communication of stakeholders
