Stakeholders meeting (nov. 09)• Emergence of a consensual definition of the VBDC:
“Integrated Management of Rainwater and Small Reservoirsfor Multiple Uses”
• Architecture of the Volta Initiative
VOLTA BDC
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 contextsmall reservoirs (small, numerous, scattered, network…)multiple users for multiple uses (diversity, co‐occurrence,…)quantities and qualities of water (requirements, impacts,…)conflicts (management, governance,…)
The expectationsThe 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 contextsand 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– …

“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 optionsfor multiple uses of small reservoirs.”
Declared growing commitment (e.g. concertation platform).
“ RESEARCHERS: have capacity in implementing integrated & transdisciplinaryresearch and modeling for small reservoirs' uses by local communities.”
Progressive common vision of small reservoir’s functioning
