Thus, land rent diminishes as you move further from the village centre. Given these assumptions, we can use a von Thünen approach to determine how far the agricultural frontier advances. The frontier will expand until the net profit or land rent is zero. r = py −wl − qk − vd = 0 (4) Equation (4) shows the variables that influence land rent and hence the limits of the agricultural frontier. Output price (p), yield (y), wage rates (w), perhectare labour requirements (l), the price of capital (q), per-hectare capital requirements (k), transport costs per km (v) and distance in km (d) determine the land rent per hectare (r).
Fourthly, dynamic investment effects resulting from higher farm income due to technological change in any system (or due to off-farm income increases) can increase the pressure on forests. vp A4003:AMA:Angelsen:First Revise:13-Mar-01 13 March 2001 09:54:20 2 Color profile: Disabled Composite Default screen Technological Change and Deforestation 4. 29 Macroanalysis: General Equilibrium Effects The previous section focused on the individual household’s response to changes in technological parameters and prices.
This probably exacerbated forest degradation, since cultivating potatoes obviously could not alleviate fuel shortages. Conversely, the introduction and increasing use of sown grasses and the rise of commercial dairy farming influenced forest cover more favourably. As in the neighbouring areas of France, these changes helped concentrate farming in the more productive lowlands and valleys and gradually lessened pressure on the higher areas. This, in turn, facilitated reforestation. It is important to emphasize, however, that changes in transport and in attitudes about forests and their management accompanied these changes in agriculture.
