Resumen

Forest and forestland are important roles and sources of livelihood for the population living in or near forests and in mountainous areas of Vietnam. The objectives of this paper analysed the change in forest resource, and policy of forestry in Vietnam. In recent several years, forest area rapidly covered an average rate of 240,000 ha/year and had about 13.39 million hectares in 2010. It has contributed to the use of bare land, job creation and improvement of livelihoods for 25% of Vietnam’s population living in mountainous areas.

Resumen

Current and emerging threats to trees and forest ecosystems require a re-evaluation of the way forest genetic resources are managed. Governments in the United Kingdom and elsewhere are committed to the restoration, expansion and creation of new woodlands. Tree populations are often adaptively differentiated from one another, so a key question underpinning the success of planting schemes is the choice of seed origin. A long held understanding is that locally sourced seeds will have the best opportunity to tolerate conditions of the planting site (local provenancing). However, the rate at which

Resumen

Ethiopia's forest resource base, which is mostly found in the southwestern highlands, supports a multitude of agricultural production systems. However, similar to the trend in other parts of the developing world, deforestation has taken a heavy toll in this part of Ethiopia. Cognisant of this, recently policies and strategies have been devised that emphasise the need for citizens' participation in natural forest management. Yet, in Ethiopia there is little field-based analytical literature that throws light on the stake that villagers have in forest resources and the workings of local level fo

Resumen

Riparian ecosystems are disproportionately biodiverse and vital to many taxa despite their scant footprint on the landscape. Yet globally they are also under the greatest human-caused threats. The loss of habitat is the greatest driver of species declines, but fragmentation may also significantly impact populations by creating barriers to dispersal. Effective conservation requires an informed understanding of species' threats and capabilities, though it is unclear whether the increasing fragmentation of riparian woodland in western North America is affecting dispersal patterns of riparian bree

Resumen

Recently, approaches to natural resource management emphasize the importance of involving communities and institutions to build capacity, limit costs, and achieve environmental sustainability. Many developing countries have policy reforms and devolution programs allowing greater involvement of local communities to manage natural resources. However, implementation of these policies has many challenges which include unaccountable representatives, limited transfer of power and benefits.

Resumen

The ability to accurately assess forest carbon storage is critical to understanding global carbon cycles and the effects of changes in land cover on ecological processes. However, existing methods for calculating carbon storage do not explicitly account for differences in carbon stored by different species of trees. Those methods that do reflect some of this variability, such as remotely-sensing canopy structure to estimate biomass, can be resource-intensive and difficult to reproduce over past or future time steps in order to assess change.

Resumen

The USDA Forest Service Southwestern Region (FS) manages over 20.5 million acres of forests and grasslands in Arizona, New Mexico and the Texas and Oklahoma panhandles. Water is one of the most beneficial natural resources used on and off these lands by humans, animals and plants. Water on forest and grasslands generally comes from precipitation which arrives in the form of snow or rain, depending on the location and season. On the ground, water infiltrates, ponds, runs off or evaporates, depending on the surface and climatic conditions. In general, precipitation that falls on these lands is f

Dynamic optimization methods have become increasingly important over the last years in economics. Within the dynamic optimization techniques employed, optimal control has emerged as the most powerful tool for the theoretical economic analysis. However, there is the need to advance further and take account that many dynamic economic processes are, in addition, dependent on some other parameter different than time. One can think of relaxing the assumption of a representative (homogeneous) agent in macro- and micro-economic applications allowing for heterogeneity among the agents. For instance, t

Intensive aquaculture of Atlantic cod is fast developing in both Northern Europe and Canada. The last six years have seen major improvements in the larval rearing protocols and husbandry techniques for this species. Although breeding programmes are currently being developed by both governmental and private institutions in the main cod producing countries (i.e. Norway, Iceland and Canada), most hatcheries still rely on the mass spawning of their own broodstock.
