BIOECONOMIC POTENTIAL FOR SILVOPASTORAL AGROFORESTRY SYSTEM IN NORTH WALES

Abstract

Purpose: This study evaluated the bio-economic potentials of temperate lowland silvopastoral agroforestry systems in North Wales, United Kingdom.Methodology: The bioeconomic analysis compared three land-use plausible scenarios (‘forestry’, ‘pasture / livestock’ and ‘agroforestry’) at 3.5% discount rate on a 10-hectare farm over a 30-year rotation using discounted cash flow analysis and national costs and prices for both livestock and tree products based on 2016 baseline data. Base case net present value (NPV) and annual equivalent value (AEV) were calculated for each production livestock grazing, farm forestry, and silvopastoral agroforestry scenario, assuming no policy interventions.Findings: Generally, results of the economic analyses indicated that under the baseline case, assuming no policy interventions, none of the options was viable. This study also showed that increase in lamb sale price, wood price, and wood yield improved the economic viability of the three investment options significantly. Again, the viability of the three investment options in this study is shown to decrease with increase in discount rates. Furthermore, this study disclosed that the application of prevailing government grant/subsidy schemes significantly improved the economic viability of the three investment options as livestock, forestry and agroforestry options showed positive NPV and AEV values at the baseline assumptions and are therefore adjudged economically viable as they all met the decision rule criteria for investment acceptance. Forestry was the most viable option with the highest NPV and AEV, followed by pasture/livestock and agroforestry options.Unique contribution to theory, practice and policy: This study underscored the imperative need for policy makers to improve awareness of the benefits of grant incomes and address farmers’ concerns about the economic viability of livestock, forestry and agroforestry investments. The results of this research will help promote greater awareness of the economic value of trees in extensively grazed landscapes in the United Kingdom as well as provide a basis for future comparisons and analysis of farm programs and ecosystem service markets.
