| Resumen: | Los campos petrolíferos de Ecuador se acercan al término de su vida económica y ya se están otorgando licencias para explotar nuevos yacimientos en la región amazónica. El hecho de que en algunas zonas de mayor valor ecológico del país pueda producirse deforestación, como sucedió en el pasado debido a las migraciones inducidas, cabe preguntarse si no sería razonable explotar estos nuevos yacimientos sin provocar deforestación. Este artículo no da una respuesta categórica pero, a partir de un proyecto de investigación anterior, presenta un ejercicio de simulación en el cual, para mostrar la pérdida económica que acarrearía la deforestación, introduce el valor económico de cuatro servicios prestados por los bosques tropicales. Sostiene además que la evaluación de las consecuencias ambientales debería tener en cuenta la prima correspondiente y se recomienda utilizar un factor de descuento hiperbólico. |

| Resumen: | We analyse the effects of technological change in agriculture on forest clearing by households in developing countries. The possible effects are found to be many and diverse, depending on the type of change and the institutional context. We conclude that agricultural intensification is certainly not the panacea that some believe it to be. |

| Título: | Local and global benefits of subsidizing tropical forest conservation |

| Resumen: | The article describes and quantifies the financial benefits of small-scale community forestry, conducted on an ecologically sustainable basis_`eco-forestry’, by customary landowners in Papua New Guinea. Through economic modelling the article also attempts to quantify the global benefits generated. Eco-forestry is subsidized by donors directly and through NGOs in its setting up and certification. Financial modelling suggests that, with a subsidy, eco-forestry is capable of generating a return to landowners that is comparable to industrial logging. While the return to logging followed by conversion to agriculture is much more attractive than eco-forestry, agriculture is an option available only in some locations. Economic modelling finds that the external economic benefits emanating from tropical forest conservation that replaces logging in Papua New Guinea are far greater in scale than the financial benefits to landowners. However, the lack of reliable data on the environmental benefits of forest conservation means that economic analysis is somewhat inconclusive. The need for further research to quantify environmental benefits is thus highlighted. The subsidization of forest conservation directly, instead of indirectly through small-scale forestry, is investigated and found to generate a similar level of economic benefits to eco-forestry. However, the cost of direct subsidization is greater. Moreover, mechanisms for direct subsidy are undeveloped in Papua New Guinea. Donors may prefer to continue to subsidize small-scale forestry where it replaces logging because of its apparent conservation and side benefits and because it is operational, while at the same time exploring and extending cost-effective models of direct conservation that have the advantage over eco-forestry of being applicable in more remote areas. Compared with industrial logging, eco-forestry contributes little to consolidated revenue. Therefore it is to be expected that eco-forestry will meet government resistance if it makes significant inroads into the allocation of logging concessions. |
