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

Zero tillage In intensive arable results in

accumulation of 0.3-0.6 t C /ha/year, with mixed rotations and cover

crops can accumulate 0.66-1.3 t C/ha/year.

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?
