This document provides an overview of rural livelihoods and social welfare. It begins by defining key concepts such as livelihood, sustainable livelihood, and vulnerability context. It then discusses livelihood assets, strategies, and outcomes. Livelihood strategies include agricultural intensification/extensification, livelihood diversification, and migration. The goal of livelihood promotion is to create sustainable livelihoods that are resilient to shocks, do not rely on external support, maintain resource productivity, and do not undermine others' livelihoods.
