Catchment management plan
Vision
A well-managed and healthy catchment that is home to
prosperous communities living in harmony with their
environment and drawing social and economic benefits from
sustainable ecosystem services.
Overall objective: Meet water demands for socio-economic
development in terms of quantity and quality and minimize
water related disasters.
Catchment management plan (cont’)
Specific objectives
1. Restore and protect critical ecosystems to reduce soil
erosion.
2. Ensure equitable and efficient allocation of water resources
to all users within the catchment taking into account the
urban development demand.
3. Control the amount of hazard risk to public infrastructure,
communities and property.
4. Reduce water pollution from urban areas caused by solid
and liquid waste disposal.
5. Maximize the socio-economic benefit of Lake Muhazi for its
users.
Alternatives
1. PASB: Planning
boundaries
by
administrative
and
sectoral
2. PCB: Planning by catchment boundaries with climate
smart agriculture: Maximize the integrated approach
3. PCB+: Planning by catchment boundaries + much extra
storage and measures to fit full IMP
4. PCB-: Planning by catchment boundaries with IMP
implemented for 50%, to avoid floods, maintain flow in
the river, and maintain water tower function.
Programme of measures/ preferred alternative (PCB-)
component
measures
I. Catchment
rehabilitation and
protection of critical
ecosystems
•
Restore and protect degraded sub catchments and wetlands within
Nyabugogo catchment.
•
Promote appropriate agriculture intensification practices by applying
climate smart agriculture
•
Improve farming methods for soil protection and conservation with
Farmers Field school (FFS)
•
Implement a payment for ecosystems services as an incentive to sustain
measures related to landscape rehabilitation and conservation.
•
•
Implementation of model mining concept
Strengthen the water governance framework and establish a CCO
(stakeholders participation).
Regulate the allocation of water resources by providing water permit
Capacity building of local water users’ committees and private operators to
improve efficiency and reduce water losses
Develop and implement water sources (intakes) protection plans that
addresses for all water supply schemes
Limit implementation of the acreage proposed by the irrigation masterplan
within the catchment to 50% to mitigate water shortages in the future.
Increase storage and small scale irrigation by constructing 7 dams
Support to Implementation of the alternative sources of energy project.

III. Control the amount of
hazard risk to public
infrastructure,
communities and
property
•
Restore and protect degraded sub catchments and wetlands within
Nyabugogo catchment (component I)
•
Increase flow capacity of Nyabugogo river and Mpazi channel
•
Increase water storage (component II and V)
IV. Reduce water
pollution from urban
areas caused by solid
and liquid waste
disposal.
•
Setting up regulatory (licensing) mechanisms in place for waste water
discharge.
centralized urban sewage system
Extension and recycling of solid waste landfill
Fecal sludge treatment plant (urban)

•
V. Maximize the socioeconomic benefit of Lake
Muhazi for its users
•
Diversifying rural source income by promoting cage fish farms in and
around Lake Muhazi to alleviate poverty
Construct a multipurpose dam on Muhazi (Flood control, irrigation and
domestic water supply)
Nyabugogo rehabilitation plan
Rehabilitation Murama Sub-catchment
Gicumbi district
Murama watershed is located in the North-Eastern part of Rwanda within the
limits of Rutare and Rwamiko sectors in Gicumbi District. The watershed has
got a surface area of 18 km2 and it is drained by river Murama which flows
into Lake Muhazi.
ISSUES
•
Excessive sediments in Murama river from the watershed caused by:
•
Topography of the watershed (steep slopes) accelerates the runoff from the
hillsides.
•
Soil erosion caused by runoff from different feeder roads and footpaths.
•
Stone quarrying and extraction in Nyagahinga, kabusunzu and Nkoto cells.
•
Poor crop yield due to inappropriate agriculture methods (Banana and
coffee)
•
Insufficient fodder for livestock (zero grazing)
•
Difficulties in fetching water for livestock (zero grazing)
Main consequence is high pollution due to sediments in the Lake Muhazi at the
Rwesero dam where river Nyabugogo flows from. Without Intervention, the
situation may continue to deteriorate with high impact on Lake Muhazi and
Nyabugogo River.
OBJECTIVES
• Erosion control by landscape rehabilitation and land
husbandry
• Promote smart agriculture practices that improve yield of
crops and contribute to soil conservation
• Livestock development by increasing fodder production and
water harvesting
DESCRIPTION
• Land husbandry/ landscape rehabilitation (terraces,
agroforestry ..)
• Buffer Zone creation
• Capacity building of farmers on climate smart agriculture
practices
• Provision of rain water tanks to vulnerable farmers
