Presentation Uganda

  1. 1. IFDC Composting initiatives in Uganda David Hirst Julius Turyamwijuka D
  2. 2. IFDC
  3. 3. IFDC Uganda's soils  Soils are getting increasingly depleted
  4. 4. IFDC Soils cont..
  5. 5. IFDC usage  Use of fertilizer is very low standing at 2-8% for inorganic fertilizer and 24.9% for organic fertilizer. IF 1 kg/ha and is below the Sub- Saharan Africa average of 9.6 kg/ha. Regions Fertiliser use Organic Inorganic Central region 34.2 11.7 Kampala 23.0 5.5 Central 1 41.5 14.7 Central 2 27.6 9.2 Eastern region 21.9 10.4 East Central 15.4 5.2 Eastern 25.9 13.6 Northern region 9.6 4.4 Mid-North 6.7 3.6 North East 2.1 2.0 West Nile 16.0 6.2 western region 33.9 6.5 Mid-West 15.9 5.9 South-Western 49.0 7.1
  6. 6. IFDC Ag/household waste  Organic fertilizer is largely ‘home grown’  ISFM techniques such as mulching, fallowing; submersion of crop residues, bunds (soil, grass and stone) to control soil erosion.  Some use of animal manure and compost  With these practices plus supplementary CS technologies such as UDP good increases in yield
  7. 7. IFDC initiatives • Landfill in Kampala (3 sites) • Uganda solid waste composting program, funded by World Bank and managed by National Environmental Management Authority (NEMA). • Biogas • Biochar – R&D
  8. 8. IFDC SWM - Lira composting facility Aerobic windrow composting; leachate is applied to windrow as a source of composting inoculum 35 tonnes p/d SW generated from 2/4 divisions. 95% of waste received is biodegradable C/N ratio is too low at 12. Two revenue sources; carbon credits. 2,500 USD received from 2011; sales 9MT per week, but, demand is low
  9. 9. IFDC Case study..challenges  Collection and sweeping isn’t done efficiently (managed by divisions)  Waste segregation is done on site manually. Some hazardous  Operational funds required to cover repairs  15 USD p/t plus transport  High application rates. 2-3 tons p/a for heavy feeder crops maize, potatoes.  A large percentage of solid waste still dumped
  10. 10. IFDCCase study 2 – Biochar research, 5km from central Kampala Raw Materials used to make Biochar organic fertilizer. • Charcoal powder- helps in retaining water and nutrients in the soil, stabilizes soil PH. Terra preta. • Inoculated animal / municipal waste from a bio- digester.- free from CH4 gases, and rich in Nitrogen. • Vermiculite and Betonite. –Rich in K, Mg, Ca, P, and other micro nutrients. • Ash- Rich in K. • Phosphates mixed with bamboo vinegar to convert P to P2O5.
  11. 11. IFDCMunicipal waste/ banana peels converted into charcoal powder.
  12. 12. IFDC Biochar trials
  13. 13. IFDC Packaging bag
  14. 14. IFDC Biochar cont  Min factory set up of capacity 3 tones daily, Three outlets, in Uganda.  Demonstrations and field trials on different crops in collaboration with other government research institutions like UIRI, MUK, NFA, Agriculture etc.  We have also done several laboratory tests  We are in process of securing product certification from Ministry of Agriculture of Uganda and IMO.  NFA sole supplier of forest inputs.
  15. 15. IFDC General challenges  In general awareness about benefits of composting limited  Lack of collection and sorting systems  Lack of incentives for private sector  Transportation costs  Poor market research/lack of marketing  More emphasis on safe disposal than compost quality  Negative balances may not be offset by MSW (1-3%) however potential from human excreta greater (17-60%)
  16. 16. IFDC Opportunities  Some skepticism about use of inorganic fertilizers  Problems with inorganic fertilizer supply chain  In Kampala 28,000 tons of waste is collected and delivered to landfill sites every month most of which is simply burnt  Other urban areas high biodegradable content of SW  Middle class consumer interested in quality  More focus on higher value crops in peri urban use of processed liquid fertilizer (by mixing and fermenting molasses, animal droppings and plant tissues), for orchards, banana plantations, horticulture crops, home flower gardens.
