4. Results…
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

17. Different steps …
Individual
surveys
Characterization
of plot types
Plot types
validation with
users
ZonAgri

18. METHODOLOGY
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

20. Modelling with ZonAgri
But
How does it work ?
(Binaba)
Andes • Ganges • Limpopo • Mekong • Nile • Volta

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
Andes • Ganges • Limpopo • Mekong • Nile • Volta

22. 1/ Inputs data
Inputs
Outputs
Andes • Ganges • Limpopo • Mekong • Nile • Volta

23. 2/ Outputs data
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 …
According to
grades
According to
the yield
level

25. 4/ Sites definition
Andes • Ganges • Limpopo • Mekong • Nile • Volta

26. 5/ “ Plot” definition
For each type of plot, one cropping
system
Andes • Ganges • Limpopo • Mekong • Nile • Volta

27. 6/ Sector definition (Right bank and Left bank)
7/ Scenarii + Results
