While peripheral rural regions in Lebanon face typical problems of lagging development and economic marginalisation, they have not been regarded as a priority for policy-makers, and significant disparities between these and other regions have emerged as a result. Local extensionists have encouraged technological innovation as a means to improving farmers’ livelihoods, and this has led to increasing input use and an intensification of agricultural production. This paper applies contrasting quantitative and qualitative methodologies to analyse the effects of such changes at the level of the overall economy of Lebanon and also to explore the impacts on rural households. A Computable General Equilibrium (CGE) model explores several simulation scenarios in which agricultural output increases due to intensification in the use of intermediate inputs. The results are evaluated at local level through the use of qualitative case-study analysis carried out in the Hermel region of northeast Lebanon. Quantitative simulations indicate that, while intensification has a positive effect overall on the Lebanese economy, the effects on rural households and the income of farmers are negative; the case-study demonstrates that, at local level, agricultural trade liberalisation, increased agricultural output and greater volatility of commodity prices has resulted in farmers opting for lower input use and more secure market forms of production.
