Sustained Yield

Sweden is a small but quite active forest country. Occupying about 0.6% of the world forest land area it holds about 15% of the international wood products market. The standing volume of forests has increased continuously since about the year of 1900. Many factors have contributed to this positive development. One is Sweden's conversion from a poor underdeveloped agrarian country to a modern industrial one. This meant a tremendous increase in agricultural efficiency and thus an important release of land which could be shifted from agriculture to forestry. But another reason for increased forest resources was and is the belief in the importance of having good forests in a remote future. The sustained or even increased yield concept is a part of this belief, materialized most of all as a more intensive silviculture.

This  paper gives an overview of the problems of forest management and proposed  strategy to enhance sustainable forest management in Indonesia. The increase  of the population number leads to need of land to support their activities,  particularly for agriculture, pasture, settlement, etc. Since forest is the  major land-use in Indonesia, deforestation is inevitable. Deforestation rate  in Indonesia increased, from 0.3 percent in 1970s to 0.6 percent of total  land in 1980's, causing socio-economic and ecological consequences. Based on  the awareness of the multiple forest functions concerning the ecological,  social and economical aspects, declined forest land area might lead to local  and global catastrophes. Hence forest resources should be stabilized or even  the area should be increased through declining deforestation, increasing  reforestation areas on degraded land, etc. In addition the forest should be  maintained based on the principles of sustainable forest management. Efforts  in sustaining forest existence and forest management in Indonesia have been  started since long time, but the success of these efforts is still to be  increased by enhancing sustainable forest management.

Deforestation remains one of the most intractable environmental problems of today. About one third the size of the original forest cover has disappeared so far. Despite continuous efforts by the world community to curb this process, deforestation continues unabated in most parts of the world, with serious consequences for the human livelihoods, eco systems, and global climate. Pakistan also faces serious problem of depletion of its forest reserves. Approximately 39000 ha of forest are being cleared every year.1 If deforestation continues at this pace, it is feared that Pakistan will lose most of its forest within the next thirty to forty years. Being a forest poor country, with forest occupying less than 5 percent of total land area,2 protection of its forest resources is a vital task. Forest management faces many challenges in Pakistan. Forests face tremendous pressure, not only from a population of 160 million people for meeting their needs3 (be it only subsistence needs), but also from market forces which have seen soaring timber prices for many years now. Forest department is ill equipped to counter these challenges. It lacks human and financial resources, and relevant technical expertise.

Lithuanian forestry has long been shaped by the classical normal forest theory, aiming for even long-term flow of timber, and the aspiration to preserve domestic forest resources, leading to very conservative forest management. With radically changing forest management conditions, climate change mitigation efforts suggest increasing timber demands in the future. The main research question asked in this study addresses whether current forest management principles in Lithuania can secure non-decreasing long-term flow of timber and carbon accumulation. The development of national forest resources and forestry was simulated for the next century using the Kupolis decision support system and assuming that current forest management is continued under the condition of three scenarios, differing by climate change mitigation efforts. Potential development trends of key forest attributes were analysed and compared with projected carbon stock changes over time, incorporating major forest carbon pools—biomass, harvested wood products and emission savings due to energy and product substitution. The key finding was that the total carbon balance should remain positive in Lithuania during the next one hundred years; however, it might start to decrease after several decades, with steadily increasing harvesting and a reduced increase of forest productivity. Additionally, incorporating the harvested wood and CO2 emissions savings in carbon balance evaluations is essential.

Abstract Background National forest inventory and forest monitoring systems are more important than ever considering continued global degradation of trees and forests. These systems are especially important in a country like Bangladesh, which is characterised by a large population density, climate change vulnerability and dependence on natural resources. With the aim of supporting the Government’s actions towards sustainable forest management through reliable information, the Bangladesh Forest Inventory (BFI) was designed and implemented through three components: biophysical inventory, socio-economic survey and remote sensing-based land cover mapping. This article documents the approach undertaken by the Forest Department under the Ministry of Environment, Forests and Climate Change to establish the BFI as a multipurpose, efficient, accurate and replicable national forest assessment. The design, operationalization and some key results of the process are presented. Methods The BFI takes advantage of the latest and most well-accepted technological and methodological approaches. Importantly, it was designed through a collaborative process which drew from the experience and knowledge of multiple national and international entities. Overall, 1781 field plots were visited, 6400 households were surveyed, and a national land cover map for the year 2015 was produced. Innovative technological enhancements include a semi-automated segmentation approach for developing the wall-to-wall land cover map, an object-based national land characterisation system, consistent estimates between sample-based and mapped land cover areas, use of mobile apps for tree species identification and data collection, and use of differential global positioning system for referencing plot centres. Results Seven criteria, and multiple associated indicators, were developed for monitoring progress towards sustainable forest management goals, informing management decisions, and national and international reporting needs. A wide range of biophysical and socioeconomic data were collected, and in some cases integrated, for estimating the indicators. Conclusions The BFI is a new information source tool for helping guide Bangladesh towards a sustainable future. Reliable information on the status of tree and forest resources, as well as land use, empowers evidence-based decision making across multiple stakeholders and at different levels for protecting natural resources. The integrated socio-economic data collected provides information about the interactions between people and their tree and forest resources, and the valuation of ecosystem services. The BFI is designed to be a permanent assessment of these resources, and future data collection will enable monitoring of trends against the current baseline. However, additional institutional support as well as continuation of collaboration among national partners is crucial for sustaining the BFI process in future.

Research Findings

Although forest devolution has become a key strategy of forestry reforms to mobilise local resources for sustainable forest management, there is growing concern about the legitimacy of this strategy. There have been escalating disputes between forestry agencies and local people as to who receives the rights to forests. Examining the policy of forest land allocation in Vietnam helps us to understand this legitimacy issue. Research findings from three case studies show trade-offs between the two policies’ goals, environmental protection and livelihood improvement, due to locals’ low awareness of the intrinsic values of forests and their lack of knowledge regarding the policy.

History Of

Britain possesses a forest area which is one of the smallest in Europe in relation to its population and land area. In the past, forests have been felled to make way for farming and to supply timber for ships, houses, fuel and metal smelting. Timber was a key to sea power, and repeatedly the availability of home timber supplies has proved crucial in time of war. The nation’s dwindling reserves of timber have been a source of anxiety since Tudor times and periodic surges of planting for timber production by private landowners took place until about 1850. Thereafter, interest faded with the advent of the iron ship, the Industrial Revolution and the availability of cheap timber imports. Govern­ ment activity was minimal until a national forest authority was formed in 1919 to create a strategic timber reserve. Since 1958 there have been frequent policy reviews to assess the changing needs of the nation for timber and the new values associated with the social and environmental benefits of forests.

Abstract The effects of defoliation caused by three foliage feeding insects, the gypsy moth (Lymantria dispar), the cherry scallopshell moth (Hydria prunivorata), and the elm spanworm (Ennomos subsignarius), on tree mortality and crown conditions were evaluated using data collected from 1984 to 1999 in the Allegheny National Forest located in northwestern Pennsylvania. While previous studies have focused on the effects of defoliation on trees in individual stands, this study differed in that it used exhaustive maps of defoliation and an areawide network of plots to assess these effects. A geographic information system was used to map the coincidence of USDA Forest Service Forest Inventory and Analysis and Forest Health Monitoring plot locations with defoliation polygons derived from aerial surveys to calculate cumulative years of defoliation for each pest. Over 85% of the Allegheny National Forest land area was defoliated at least once during the 16-year period from 1984 to 1999. Frequency of defoliation by specific defoliator species was closely associated with the dominance of their primary hosts in stands. Frequency of defoliation was often associated with crown dieback and mortality, but these relationships were not detectable in all species. These results suggest that when impacts are averaged over large areas (such as in this study) effects of defoliation are likely to be considerably less severe than when measured in selected stands (as is the approach taken in most previous impact studies).
