Opportunities and ProblemsOpportunities and ProblemsWide area with potential for agricultural
production (1.12m Km2), pop. (>80m)One of the oldest agrarian countries with IKHigh land degradationSmallholder farmers with open access

CO2e Agriculture- 50 percentMethane 65 Mt CO2eFertilizer ~10 Mt CO2eForestry- 37 percent55 Mt CO2e (deforestation for
agricultural land, fuel wood logging)All transport, Industry, power and

Agriculture (4.4%) increase from 75 to 185 Mt CO2e due to increase in cattle population, increase in cultivated land (crops production) and synthetic fertilizer
Forestry (2.6%) - average growth of cropland and increase in population leading to higher fuel wood consumption
The opportunity for carbon sink in the The opportunity for carbon sink in the agriculture sectoragriculture sector
The CRGE planned the GHG to be around 250 Mt CO2e based on four pillars:
One of them is - Improving crop and livestock production practices for higher food security and farmer income while reducing emissions.
Therefore, we can work in soil, water, agronomy, etc
Vegetation – mixed agriculture – agroforestry

ConclusionConclusionProjects under smallholder farming practices solve
many problems through recycling of organic matterMixed farming practice is interconnecting each other
and diversify means of income, survival, diversity, innovation, etc based on social problems.
Landscape approach become attractive the government – satisfying all
The government policy is supportive for such projects - they coincide with the government policy and Growth and Transformation Plan, National Action Plan for Adaptation
RecommendationsRecommendationsEnough attention and respect for smallholder
farming b/c it improves environment, livelihood, social
Adequate promotion, including training and follow-up in low inputs and mixed agriculture could contribute substantially to becoming food secure
Government and Civil Society cooperation is very fundamental for scaling up/out
Clarity – requiredClarity – required
Who should know the gain and loss of the Climate change
How do we collaborate for a stronger result?
Do we need to see the contribution of smallholder farming by one eye (carbon)? Why not beyond? – where is the value of biodiversity & food security?
