The Forest Rights Act 2006 was designed to provide secure property rights to the forest dwellers of India. This paper analyses the effect of the legislation and finds that it has proved largely ineffective at meeting its objectives. There is evidence to suggest that the implementation of the Act has been undermined by bureaucratic interests. 相似文献

This paper presents a new forest harvest scheduling model taking into account four conflicting objectives. The economic factor of timber production is considered and also aspects related to environmental protection. We also incorporate adjacency constraints to limit the maximum contiguous area where clear-cutting can be applied. The model proposed is applied to a timber production plantation in Cuba located in the region of Pinar del Río. One factor to be taken into account in Cuban plantations is that the forest has a highly unbalanced age distribution. Therefore, in addition to the classical objectives of forest planning, we have the objective of rebalancing age distribution by the end of the planning horizon. Explicitly, the four objectives considered in the model are: (a) obtaining a balance-aged forest; (b) minimizing the area with trees older than the rotation age; (c) maximizing the NPV of the forest over the planning horizon; and (d) maximizing total carbon sequestration over the whole planning horizon. The solution to the proposed model provides a set of efficient management plans that are of assistance in analysing the tradeoffs between the economic and ecological objectives. The model is also applied to randomly generated simulated forests to compare its performance in other contexts. As the problem is a multiobjective binary nonlinear model, a metaheuristic procedure is used in order to solve it. 相似文献

In the last decade Slovenia has experienced more frequent natural disasters in forests. The most severe and widespread one that affected Slovenian forests, which cover more than a half of Slovenian territory, was a large-scale ice storm in early February 2014. This study aims to investigate the effect of the public support on the recovery of forest farms affected by the 2014 ice storm. Analyses focus particularly on the ability of Slovenian forest farms’ income recovery in a short-time period. The economic resilience of forest farms in the absence of forest disaster payments due to the absence of legal certainty for disaster aid in 2014 and 2015 provides an interesting framework for identifying the income effect of Common Agricultural Policy (CAP) payments. The Farm Accountancy Data Network has been used with applied statistical and regression methods to estimate the public support effect on selected woodland area size samples. Results suggest a positive effect of CAP payments on farm income recovery. The magnitude of the effect is high and significant for the less favoured area and disaster payments that were given for farm production loss in the 2013 drought. Although the magnitude of the effect is weak, investment payments show a significant positive effect on farm income recovery for all studied forest farm samples. 相似文献

The bio-textile products made from certified wood fibers are an important product innovation able to diversify the wood product portfolio of enterprises and to increase environmental sustainability. In this paper, we estimate Italian consumers' willingness to pay for three bio-textile products made from certified wood (socks, T-shirt and shirt). Data were collected face-to-face to a sample of 696 consumers through Contingent Valuation. The results from the Cameron and Huppert model show a significant premium price, ranging from 64% to 128% depending on the products, and that respondents with a higher environmental concern are more willing to pay for bio-textile products. Nevertheless, the price turned out to be a key determinant, evidencing how it can constitute a barrier to a more sustainable consumer behaviour. These results are important for the European wood-based industries’ businesses, currently based on stagnant market of traditional wood products, since they indicate there is room for a profitable diversification in bio-textile products. An increased market of bio-textile products can contribute to reduce the fossil fuel dependency of the European Union economy. 相似文献

This study sought to understand how the Ecuadorian Ministry of the Environment systematic structure works through their so-called Forest Administration System (FAS). This system has generated different perceptions among those that are involved in this system the repercussions of the informalities of the population that subsists off the exploitation of their forests which have changed the market chain from a framework of legality to illegality and the institutional barriers and the costs that have to be met. This are only part of the difficulties faced by the FAS. In Ecuador, the Ministry of the Environment has tried to facilitate processes since 2013, when they allowed for a greater participation of the owners of hardwood farms and thus legalized the cutting and subsequent sale of the hardwood to generate more income for their family, in order to avoid the use of intermediaries and informal exploitation (illegal). It was found that the application of the FAS has achieved big changes, but there are still some faults to correct. 相似文献
