18 Ecuador - Carchi

19 Capacity development through IPM Farmer Field Schools Participatory technology development (CIALs) Exchanges among communities Activities centered on men

20 Ecuador - Carchi Activities centered on women Knowledge strengthening (IPM FFS, directed training) Introduction of IPM to grade school curriculum Propaganda campaigns

21 Ecuador - Carchi Community level action Strengthening community participation through: –Exchange of information and public discussion –Analysis of tradeoffs –Site visits Advocacy: –Elimination of highly toxics –Public investment in IPM

22 Ecuador - Carchi Farmer field schools Reduction in pesticide use, while maintaining production (19 t/ha): 12 to 7 applications (60% less active ingredient by area) Reduction in use of most toxic pesticides: Metamidaphos (40%), Carbofuran (75%) Improved profitability: Cost/tm $21 (22%); net benefit/ha. $722 (36%); return on investment: from 120% to 145%

23 TOA projects Peru – Cajamarca Potato-pasture-grain system Low external inputs Steep slopes High altitude ( m.a.s.l.) Average annual rainfall <700mm/yr Temperatures around 10°C

24 Peru - Cajamarca Stakeholder meetings Indicators Economic indicators Water erosion Carbon sequestration

25 Peru - Cajamarca Stakeholder meetings Scenarios Terracing Carbon contracts Climate change

26 Cajamarca - terracing

27 Cajamarca – climate change

28 Cajamarca - terracing % Subsidy % profitable terraced fields Steep slopes Minor slopes Incl. maintenance subsidy Construction subsidy

29 Cajamarca – carbon sequestration Carbon (metric tons) Price ($/metric ton) Terraces + Agro-forestry (high carbon) Terraces (high carbon) Terraces (Low carbon)

30 TOA projects Senegal - Njoro Peanut-millet rotation Low external inputs Rolling/flat terrain Low altitude (<50 m.a.s.l.) Semi-arid climate (<700 mm/yr) Average temperature 24° C

31 Senegal - carbon supply curves Carbon (Mg) C Price ($/Mg) Fertilizer Fertilizer + Crop residues Note threshold effect of increased labor costs plus transaction costs.

32 TOA projects Kenya - Machakos Mixed crop-livestock system Low external inputs Steep slopes Altitude ( m.a.s.l.) Semi-arid climate ( mm/yr) Average temperature 20° C
