Management of Rainwater and Small Reservoir for Multiple Uses in the Volta River Basin Management of Rainwater and Small Reservoir for Multiple Uses in the Volta River Basin Presentation Transcript

  • 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
  • Objectives 1. Diagnoses 2. Typology of uses and users 3. Pilot activities 4. Participatory modelling (G-eau) Andes • Ganges • Limpopo • Mekong • Nile • Volta
  • Methodology QUESTIONARY Step 1 LOCAL INSTITUTIONS - Agriculture livestock Environment Health Local collectivity Step 2 Andes • Ganges • Limpopo • Mekong • Nile • Volta
  • Results… Andes • Ganges • Limpopo • Mekong • Nile • Volta
  • Diagnoses 4 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 season Fisher 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) Andes • Ganges • Limpopo • Mekong • Nile • Volta
  • 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
  • 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 Andes • Ganges • Limpopo • Mekong • Nile • Volta
  • A ZonAgri Participatory Modelling of Agricultural Activities and Uses of Water in Boura (BF) and Binaba (GH) Lorraine RENAUDIN, JC Poussin
  • 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
  • Different steps … Individual surveys Characterization of plot types Plot types validation with users ZonAgri modelling ZonAgri model validation with users Scenarii Andes • Ganges • Limpopo • Mekong • Nile • Volta
  • 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 ZonAgri But 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 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
  • 1/ Inputs data Inputs Outputs Andes • Ganges • Limpopo • Mekong • Nile • Volta
  • 2/ Outputs data Andes • Ganges • Limpopo • Mekong • Nile • Volta
  • 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 Andes • Ganges • Limpopo • Mekong • Nile • Volta
  • 4/ Sites definition Andes • Ganges • Limpopo • Mekong • Nile • Volta
  • 5/ “ Plot” definition For each type of plot, one cropping system Andes • Ganges • Limpopo • Mekong • Nile • Volta
  • 6/ Sector definition (Right bank and Left bank) 7/ Scenarii + Results Andes • Ganges • Limpopo • Mekong • Nile • Volta
  • What’s about Boura situation ? Andes • Ganges • Limpopo • Mekong • Nile • Volta
  • Already done … 1/ Individual surveys Yields for 2/ Beginning of the plot each type characterization : types Corikab Yield (kg/ha) 6000 5000 4000 3000 2000 3/ Plot location characterization (Zone 1, Zone 2, Zone 3, upland, lowland) 1000 0 1,1,0 0,0,0 1,0,0 1,1,0 1,0,1 0,1,0 0,0,1 1,1,1 1,1,0 0,1,1 1,1,0 Andes • Ganges • Limpopo • Mekong • Nile • Volta
