Diagnoses, typology of uses and usersBoura-BURKINA FASO
Andes • Ganges • Limpopo • Mekong • Nile • Volta
Objectives
1. Diagnoses
2. Typology of uses and users
3. Pilot activities
4. Participatory modelling (G‐eau)

Diagnoses4 users groups
1. Farmers (CORICAB, PIAME, 2 informal groups )
2. Livestock
3. Fishermen
4. Domestic users
Andes • Ganges • Limpopo • Mekong • Nile • Volta
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
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
Typology (users)Livestock (extensive)
Sedentary livestock: 4 farmers groups, castles, sheep, goat.
Transhumant livestock: Castles mainly come from Burkina and
Ghana during dry seasonFisher
One group (Akawari)
Gill net, cast net
Fish farming (fixed enclosure,
floating structures)
Hook fishing
Andes • Ganges • Limpopo • Mekong • Nile • Volta
Typology (users)Domestic use
Brick confection
Household (dishes, washing)
Others (bikes washing, …)
Andes • Ganges • Limpopo • Mekong • Nile • Volta
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
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
Some difficulties …Toum’Hositi and Toum’Kiente (gardening vegetables)
No management (manual irrigation)
Animals damage (no protection)

Pilot activitiesRice production/ participatory approachObjective:
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
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

METHODOLOGY
Andes • Ganges • Limpopo • Mekong • Nile • Volta
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
Modelling with ZonAgriBut
How does it work ? (Binaba)
Andes • Ganges • Limpopo • Mekong • Nile • Volta
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
