The document summarizes the Volta Basin Development Challenge (VBDC) project, specifically the V3 component focused on integrated management of small reservoirs. It discusses that V3 aims to develop sustainable management options for small reservoirs to improve productivity while ensuring resilience. V3 studies water uses and users, assesses needs and impacts, and seeks to reach multiple objectives like perpetuating infrastructure and improving water quality through integrated management approaches. The project is making progress through field activities, capacity building, and developing a common understanding of small reservoir functioning with local stakeholders.

• Emergence of a consensual definition of the VBDC:
“Integrated Management of Rainwater and Small Reservoirs
for Multiple Uses”
• Architecture of the Volta Initiative
V1 – Targeting and scaling out
V2 – Integrated management of rainwater for crop‐livestock agroecosystems
V3 – Integrated management of small reservoirs for multiple uses
V4 – Sub‐basin management and governance of rainwater and small reservoirs
V5 – Coordination and learning for adaptive management and change

The context
small reservoirs (small, numerous, scattered, network…)
multiple users for multiple uses (diversity, co‐occurrence,…)
quantities and qualities of water (requirements, impacts,…)
conflicts (management, governance,…)
The expectations
The V3 project will develop sustainable options of management of small
reservoirs to improve the productivity AND to insure the resilience.
It will identify uses and users, assess their needs, clarify social and ecological
determinants, control health consequences.
For individual small reservoirs considered within their biophysical contexts
and their economical dynamics.

Integrated management aim at several objectives:
– Perpetuating infrastructures
– Protecting / improving water quality for various uses
– Reaching / enhancing water productivity potentials
– Seeking for equity
Objectives that need
Knowledge on processes at the adequate scales
– (e.g.) Catchment for local physical processes
– (e.g.) Ecosystems connectivity for local ecological processes
– (e.g.) Market opportunities for local economic processes

Progress
“LOCAL COMMUNITIES: Are integrating new knowledge and skills acquired
from the project into their production systems at the community and farm level.”
Declared increasing awareness (e.g. biophysical interactions between uses)
“DISTRICT LEVEL”: Government officials from the Ministries of Agriculture, water
resources, fisheries and livestock, and LOCAL ADMINISTRATIVE AUTHORITIES,
are using research results and recommendations on improved management options
for multiple uses of small reservoirs.”
Declared growing commitment (e.g. concertation platform).
“ RESEARCHERS: have capacity in implementing integrated & transdisciplinary
research and modeling for small reservoirs' uses by local communities.”
Progressive common vision of small reservoir’s functioning
