This can relieve the pressure to clear additional forest for crops and livestock. Eventually, farmers may even abandon areas, paving the way for reforestation (by natural regeneration or plantation). Similarly, transportation improvements can facilitate the concentration of agricultural production in more fertile areas and allow people in other regions to purchase their food from elsewhere and stop growing crops on marginal lands. How population pressure and systemic stress affect resource management has long been debated.
1 shifts upward, the household will be able to achieve the same amount of income using less labour, capital and land. Thus, the supply of labour simply decreases in response to technological progress. In this case, there is no conflict between the welfare and conservation objectives. , 1998; Angelsen, 1999a). In summary, if farmers face a set of perfect markets, technological change will spur deforestation. When farmers are labour (capital)-constrained, as is often the case at the forest margin, labour (capital)-saving technological progress will probably lead to more deforestation.
Braudel (1990: 277) has called these grasses the ‘the motor of a powerful and necessary agricultural revolution’. Already established in some areas, such as the Paris basin, by the 1760s, they slowly expanded for several decades and then took off after the 1830s (Jones, 1990). Cattle numbers rose, largely on the more productive improved pastures, but the sheep herd declined progressively from around mid-century. This took pressure off the commons and the unimproved pastures and forest, which facilitated tree regeneration or at least reduced the pressure on the remaining forest and scrub.
