Results suggest that agricultural production, livestock production and stock from previous harvest and as well as the sale of agricultural product, the sale of garden product, picking and the sale wild fruits and leafy vegetables, small business, crafting, project transfer, the sale of firewood and straw and the sale livestock product are the optimal combination food and income diversification decisions to enhance rural household resilience building capacity. Results finally suggest that collective decision made about food and income diversification decisions is more welfare enhancing that individual decision.
