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

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

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)

21. Each plot can be compared to a farming system
in a given geographic region with :
Inputs

a set of production
activities
A given size
a certain site
Plot with a given
strength in a certain sector
