| This report summarizes preliminary findings of the Mexican National Database and Community Survey Project which examines linkages between institutional characteristics in Mexico’s common property forestry sector and economic and environmental outcomes. Framing the Mexican agrarian community as a unit of analysis characterized by its history, individual members, resources, civic structure and property rights, we use institutional economic analysis to motivate project design and research on three aspects of Mexican community forestry governance: first, how communities have engaged forest resources to participate in forestry markets; second, how internal models of forestry management are reflect historical circumstances and practices, policy trends and... |

| Corruption in the forest sector of Swat, Pakistan is impairing the sustainable management of forest. We analyze corruption in a case study setting against the backdrop of the reform options that are most often cited as possible solutions. As we highlight in this study, the crime and punishment approach is not feasibly implemented if the overall institutional environment is weak. Since countrywide overhaul of corruption through sweeping reform programs, the other reform approach, is a difficult and lengthy task, there is a need for an alternative kind of reform. In the case of a corruption-ridden centralised forest management regime, institutional reform should move away from enforcement of existing institutions and promote communal management of natural... |

| ABSTRACT This study focuses on the effects of different thinning regimes on clonal Eucalyptus plantations growth. Four different trials, planted in 1999 and located in Bahia and Espírito Santo States, were used. Aside from thinning, initial planting density, and post thinning fertilization application were also evaluated. Before canopy closure, and therefore before excessive competition between trees took place, it was found that stands planted under low densities (667 trees per hectare) presented a lower mortality proportion when compared to stand planted under higher densities (1111 trees per hectare). However, diameter growth prior to thinning operations was not statistically different between these two densities, presenting an overall mean of 4.9... |

| A segunda geração da tecnologia Modelo Digital de Exploração Florestal (Modeflora) utiliza-se de um sistema de sensoriamento remoto ativo de escaneamento a laser conhecido como LiDAR (Light Detection and Ranging). Esse equipamento emite radiação eletromagnética a um dado comprimento de onda, sob uma taxa de frequência de repetição para detecção de objetos. Ao ser atingido pelo laser, o alvo reflete a radiação e o equipamento LiDAR detecta o retorno do sinal refletido. Por meio das propriedades da luz refletida no objeto é possível fazer o cálculo da distância, entre o emissor e o objeto que refletiu o pulso, e dessa forma obter o posicionamento geográfico do alvo. |

| Eucalyptus plantations are normally found in vulnerable ecosystems such as steep slope, soil with low natural fertility and lands that were degraded by agriculture. The objective of this study was to obtain Universal Soil Loss Equation (USLE) factors and use them to estimate water erosion risk in regions with eucalyptus planted. The USLE factors were obtained in field plots under natural rainfall in the Rio Doce Basin, MG, Brazil, and the model applied to assess erosion risk using USLE in a Geographic Information System. The study area showed rainfall-runoff erosivity values from 10,721 to 10,642 MJ mm ha-1 h-1 yr-1. Some soils (Latosols) had very low erodibility values (2.0 x 10-4 and 1.0 x 10-4t h MJ-1 mm-1), the topographic factor ranged from 0.03 to... |
