    Chile

    A multitemporal analysis to determine the land cover change was conduced in the pre-Andean range of Maule region of Chile. We used satellite imagery from the year 1989 and 2003 to analyze the likely causes of native forest change. In this period, there was a reduction in native forest area of 44% in the study area, which is equivalent to an annual forest loss rate of 4.1%. The native forest area is replaced by shrublands (29%) and exotic forest plantations (27%). A great proportion of current exotic forest plantations are established on lands that were native forest in 1989 (63%).

    The paper estimates the regional economic impact of renewable energy development (inv)based on the use of biomass. The regional level is Andalusia. The analysis is carried out under the assumption that achieves the goal of renewable energy development set in Andalusian Sustainable Energy Plan (PASENER) 2007-2013. To estimate the economic impact, a General Equilibrium Model (CGE) is used based on the Social Accounting Matrix (SAM) updated for Andalusia in 2008. The results show that if the goal of PASENER is met, there might be an increase production of 4.02%.

    Costa Rica

    The financial behavior of three schemes for payments for environmental services (PES) adjusted to the forest value (FV) was assessed, starting from a first forest harvest, which were classified into two types according to the dominance of Pentaclethra macroloba combined with palms (Forest Pp) or combined with Carapa guianensis (Forest Pc). In these forests, common production functions of sustainable forest management (SFM), and functions of profitability were elaborated for two conditions of harvesting during a cutting cycle.

    This paper presents some theoretical and technical conclusions on the contribution of Forest Ecosystem Services to the reduction of deforestation rates in highly vulnerable areas of the Costa Rican Central Mountain Range and to the regulation of watersheds, and the resulting increased profitability of investments in hydro-electrical power plants.

    Chile

    In the Región de Aysen, Chile, Nothofagus antarctica (ñirre or Antarctic beech) forms puré forests called shrubby beech forests and secondary mixed shrub of anthropogenic origin. The aim of this work is to characterize the insect fauna associated to the foliage of Antarctic beech forests and scrublands in the Baker river basin. Insects were collected in spring (October 2006) and summer (January 2007), in five beech forests and 10 scrub patches from latitudes 47°2' S - 72°48' W to 47°15' S - 73° W. Six orders of insects were identified, being Coleóptera the most diverse.

    Argentina

    By the late 19th century, indigenous populations in Argentina's regions of Pampa, Patagonia and Chaco were subordinately incorporated into capitalist economy, through a series of genocidal and destribalization policies that have been thoroughly examined in previous studies. However, the circumstances of their integration and the strategies that indigenous actors displayed have not been systematically analyzed yet.
