Management of Rainwater and Small Reservoir for Multiple Uses in the Volta River Basin
1. Volta Basin Development Challenge
Management of Rainwater and Small
Reservoir for multiple uses
2012 Annual Reflection Meeting
Diagnoses, typology of uses and users
Boura-BURKINA FASO
Adama Traoré
2. Objectives
1. Diagnoses
2. Typology of uses and users
3. Pilot activities
4. Participatory modelling (G-eau)
Andes • Ganges • Limpopo • Mekong • Nile • Volta
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
Andes • Ganges • Limpopo • Mekong • Nile • Volta
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)
Andes • Ganges • Limpopo • Mekong • Nile • Volta
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

15. A ZonAgri Participatory Modelling of
Agricultural Activities and Uses of
Water in Boura (BF) and Binaba (GH)
Lorraine RENAUDIN, JC Poussin
16. Overview
1/ Methodology
2/ Modelling with ZonAgri but how
does it work ? (Binaba)
3/ What’s about Boura’s situation ?
Andes • Ganges • Limpopo • Mekong • Nile • Volta
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
Different types of plots (grades + Yield level + Plot
location)
Andes • Ganges • Limpopo • Mekong • Nile • Volta
21. Each plot can be compared to a farming system
in a given geographic region with :
Inputs
Output
a set of production
activities
A given size
a certain site
Plot with a given
strength in a certain sector
Andes • Ganges • Limpopo • Mekong • Nile • Volta
24. 3/ Production unit data
And the quantity of inputs for each type of plot
Entering the different types of plot …
