This document summarizes a meeting to discuss management of rainwater and small reservoirs for multiple uses in Boura, Burkina Faso. Surveys were conducted to diagnose uses and users, including farmers organized into formal groups, livestock herders, fishermen, and domestic users. The surveys identified four main user groups and characterized the typology of each. Challenges for farmer groups were discussed. Pilot activities on rice production using improved varieties were outlined. Participatory modeling of agricultural activities and water uses was demonstrated using the ZonAgri model.

5. Diagnoses
4 users groups
1. Farmers (CORICAB, PIAME, 2 informal groups )
2. Livestock
3. Fishermen
4. Domestic users
Andes • Ganges • Limpopo • Mekong • Nile • Volta

6. Typology (users)
Farmers (formal groups)
1. CORIKAB: since 1989, 300 farmers, 62 ha (0.2 & 0.5
ha/person) , downstream, rice & gardening vegetables , dry
season, gravitionary system on 3 zones
2. PIAME: since 2007, 130 farmers, 40 ha (0.12 & 0.5
ha/farmer) right shore, gardening vegetables in dry season
(tomato, onion, eggplant, cabbage, …), motopump
irrigation, cereals in rain season. Dry season maize in 2012

7. Typology (users)
Agriculture (informal groups)
1. Toum’Kiente: informal groups, left shore, 20 ha,
gardening vegetables in dry season, (tomato, onion)
2. Toum’Hositi: informal groups, left shore, 10 ha (0.12
ha/farmer), legumes in dry season (tomato, onion, …)
Andes • Ganges • Limpopo • Mekong • Nile • Volta

8. Typology (users)
Livestock (extensive)
Sedentary livestock: 4 farmers groups, castles, sheep, goat.
Transhumant livestock: Castles mainly come from Burkina and
Ghana during dry season
Fisher
One group (Akawari)
Gill net, cast net
Fish farming (fixed enclosure,
floating structures)
Hook fishing
Andes • Ganges • Limpopo • Mekong • Nile • Volta

9. Typology (users)
Domestic use
Brick confection
Household (dishes, washing)
Others (bikes washing, …)
Andes • Ganges • Limpopo • Mekong • Nile • Volta

10. Some difficulties …
CORIKAB (rice)
Water management for the 3 zones, rate of flow low in 3rd
zone (extreme downstream)
No communication/collaboration between zones
Damage on irrigation canal I and II (Flood…)
Low use of improved varieties + few knowledge of
production techniques => low yields, no efficient water use
Fertilizer supply
Andes • Ganges • Limpopo • Mekong • Nile • Volta

11. Some difficulties …
PIAME (gardening vegetables)
Damage on irrigation installation
(important water flight)
Frequent motopump breakdown
Animals damage (no protection)
Andes • Ganges • Limpopo • Mekong • Nile • Volta

12. Some difficulties …
Toum’Hositi and Toum’Kiente (gardening vegetables)
No management (manual irrigation)
Animals damage (no protection)

13. Pilot activities
Rice production/ participatory approach
Objective:
To introduce news improve varieties,
To introduce news technical production
Methodology
6 varieties : 3 local (Konkoulamoui, zelemoui, Gongomoui), 3
improved varieties (FKR 56 N, FKR 60 N, FKR 62 N)
Production technologies (sowing, irrigation, fertilizer,
Andes • Ganges • Limpopo • Mekong • Nile • Volta

14. Typology (uses)
CORIKAB and PIAME cases:
Cultural superficies, crops
Input: water, seeds, fertilizer, pesticides (herbicide,
insecticide), work (plowing, sowing, weeding, irrigation,
harvest and beating), production
Output: selling
Some data for CORIKAB / Classification and ZonAgri
No more informations on PIAME and both informal groups

19. Individual survey
(Prices, Labour time, inputs quantities, yield, water
quantity)
2 grades according to 3 (Rice) or 4 (gardening vegetable) criteria
Nursery duration Nitrogen Units Pest control Weeds control

21. Each plot can be compared to a farming system
in a given geographic region with :
Inputs a set of production
Output activities
A given size
a certain site
Plot with a given
strength in a certain sector
