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

  1. 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. 2. Objectives 1. Diagnoses 2. Typology of uses and users 3. Pilot activities 4. Participatory modelling (G-eau) Andes • Ganges • Limpopo • Mekong • Nile • Volta
  3. 3. Methodology QUESTIONARY Step 1 LOCAL INSTITUTIONS - Agriculture livestock Environment Health Local collectivity Step 2 Andes • Ganges • Limpopo • Mekong • Nile • Volta
  4. 4. Results… Andes • Ganges • Limpopo • Mekong • Nile • Volta
  5. 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. 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. 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. 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. 9. Typology (users) Domestic use  Brick confection  Household (dishes, washing)  Others (bikes washing, …) Andes • Ganges • Limpopo • Mekong • Nile • Volta
  10. 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. 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. 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. 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. 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 Andes • Ganges • Limpopo • Mekong • Nile • Volta
  15. 15. A ZonAgri Participatory Modelling of Agricultural Activities and Uses of Water in Boura (BF) and Binaba (GH) Lorraine RENAUDIN, JC Poussin
  16. 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. 17. 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
  18. 18. METHODOLOGY Andes • Ganges • Limpopo • Mekong • Nile • Volta
  19. 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. 20. Modelling with ZonAgri But How does it work ? (Binaba) Andes • Ganges • Limpopo • Mekong • Nile • Volta
  21. 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
  22. 22. 1/ Inputs data Inputs Outputs Andes • Ganges • Limpopo • Mekong • Nile • Volta
  23. 23. 2/ Outputs data Andes • Ganges • Limpopo • Mekong • Nile • Volta
  24. 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 Andes • Ganges • Limpopo • Mekong • Nile • Volta
  25. 25. 4/ Sites definition Andes • Ganges • Limpopo • Mekong • Nile • Volta
  26. 26. 5/ “ Plot” definition For each type of plot, one cropping system Andes • Ganges • Limpopo • Mekong • Nile • Volta
  27. 27. 6/ Sector definition (Right bank and Left bank) 7/ Scenarii + Results Andes • Ganges • Limpopo • Mekong • Nile • Volta
  28. 28. What’s about Boura situation ? Andes • Ganges • Limpopo • Mekong • Nile • Volta
  29. 29. 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
