ABSTRACTAfter reviewing the Kyoto Protocol rules for carbon sequestration accounting and the different carbon accounting methods proposed in the literature for forest management, for reforestation and, more recently, for avoided deforestation or degradation, we discuss possible carbon accounting rules for a post-Kyoto world. We then apply the results of this discussion to micro-applications in an Annex I country (Spain) and in a non-Annex I country (Tunisia), comparing avoided degradation with reforestation alternatives. In both areas we focus on Mediterranean forest, one of the world's hotspots of biodiversity. We calculate CO2 break-even prices, including in the analysis not only commercial values, but also, where these are relevant, existing subsidies. We also investigate social preferences for avoided degradation and reforestation using stated preference methods. Our results support the convenience of a change in focus for European Union subsidies from reforestation to avoided degradation.

Gunung Dahu Research Forest (GDRF) is a 250 ha tropical degraded land reforested by native dipterocarps species. The reforestation success was valued by evaluating the planted trees’ growth performance, their potential timber stock, natural regeneration capacity, soil improvement, biological interdependence, and environmental services. This scientific report used a combination of literature review and also primary data processing to describe the reforestation success within the area. A hilly species of Shorea platyclados showed the best growth performance with its average diameter and height of 43 cm and 23 m, respectively, with its mean diameter annual increment of 2.1 cm/year and the predicted standing stock at 220 m3/ha. Six Shorea species were identified to show their natural regeneration capacity and the occurrence of ectomycorrhizal fruiting bodies, predominantly by the genus Rusula, determined the establishment of biological interdependency at the site. Reforestation improved soil organic matters as revealed by high soil porosity (51.06–52.32%) and infiltration rate (120–155.33 mm/h). The reforested landscape also ensures a continuous water supply and provides an economic benefit for the community. Thus, planting native trees for reforesting degraded tropical landscapes is prospective and may deliver multiple benefits in an ecological and economic view.

The phenomenon that occurs is the amount of deforestation that occurs due to forest fires during the dry season, making forest areas dry. That makes a lot of forest land that has been burned to be barren without reforestation. So that the loss of biodiversity in the forest area and damage the existing ecosystem. A project is needed to reforest burnt forest land to minimize biodiversity loss and even restore it. The research method focused on the literature related to deforestation. The design method applied is based on tectonic principles and focuses on the Knock-down system to maximize reforestation on the forest land. In addition, applying Kevin Lynch's principles in the context of the city into the forest becomes a new thought in designing a reforestation project. The presence of a reforestation project and monitoring of burned forests are expected to be an example to minimize the loss of biodiversity and even restore it so that the forest ecosystem that supports human life can survive and not be lost. Keywords: deforestation; reforestation; tectonic; knock-downAbstrakFenomena yang terjadi merupakan banyaknya deforestasi yang terjadi akibat kebakaran hutan saat musim kemarau yang membuat kawasan hutan menjadi kering. Hal ini membuat banyaknya lahan hutan yang bekas terbakar menjadi tandus tanpa dilakukannya reboisasi kembali. Sehingga hilangnya keanekaragaman hayati yang ada kawasan hutan itu dan merusak ekosistem yang ada. Diperlukannya suatu proyek untuk mereboisasi lahan hutan bekas terbakar untuk meminimalisir hilangnya keanekaragaman hayati dan bahkan mengembalikannya. Metode penelitian yang dilakukan difokuskan melalui literatur-literatur yang berhubungan dengan deforestasi. Metode desain yang diterapkan berdasarkan pada prinsip tektonik dan juga berfokus pada sistem bongkar pasang sehingga dapat memaksimalkan reboisasi pada lahan hutan tersebut. Selain itu menerapkan prinsip Kevin Lynch dalam konteks kota ke dalam hutan menjadi suatu pemikiran baru dalam merancang suatu proyek reboisasi di hutan. Hadirnya proyek reboisasi dan pengawasan hutan bekas terbakar ini diharapkan dapat menjadi salah satu contoh untuk meminimalisir hilangnya keanekaragaman hayati dan bahkan mengembalikannya sehingga ekosistem hutan yang menopang kehidupan manusia dapat bertahan dan tidak hilang.

The article discusses the issues of restoration of forest areas damaged by fires. Forest fires cause not only environmental, but also material damage. If it is almost impossible to compensate for the environmental damage caused by the ingress of combustion products into the atmosphere, then restoring forest resources is a feasible task. Currently, the same technologies are used for reforestation in fire-damaged forest and burnt areas as for reforestation in forest sites after deforestation. However, their efficiency, taking into account natural and industrial conditions, is often not at the highest level. The aggravation of the problem of forest fires necessitates the use of highly effective domestic methods and technical means for reforestation after fires. The purpose of this study is to determine the level of technical development of domestic modern methods and technical means of restoring forest areas damaged by fires. In the course of the patent information search and analysis of scientific and technical literature, modern methods and technical means for restoring forest plantations in areas damaged by fires were studied, and the collected information was analyzed. The effectiveness of the use of a mulch working body for the preliminary preparation of a forest area disturbed by fires is noted.

ABSTRACT The mitigation of CO2 emission through high-productivity systems associated with restoration of degraded sites have been increasingly common, highlighting the importance of estimates of the amount and distribution of plant biomass in different ecosystems and under different management systems. The aim of this study was to investigate the influence of planting and soil characteristics and the type of management performed over the aboveground biomass accumulation in two reforestation projects with native species, implanted through Taungya agroforestry system. The differences in aboveground biomass accumulation were probably influenced by agroforestry management, since these variations showed to be independent of age (considered within the age range in this study), the spacing, the species composition, and soil fertility. The values of aboveground biomass are similar to those reported in the literature for other reforestation projects with native species of similar ages.

Testo completoAbstract (sommario):
Reforestation and restoration using nursery-produced seedlings is often the most reliable way to ensure successful establishment and rapid growth of native plants. Plant establishment success—that is, the ability for the plant to develop within a set period of time with minimal further interventions needed—depends greatly on decisions made prior to planting, and yet nursery-grown plants are often produced independently of considering the range of stressors encountered after nursery production. The optimal plant or seedling will vary greatly with species and site (depending on edaphic and environmental conditions), and in having the biological capacity to withstand human and wildlife pressures placed upon vegetative communities. However, when nursery production strategies incorporate knowledge of genetic variability, address limiting factors, and include potential mitigating measures, meeting the objectives of the planting project—be it reforestation or restoration—becomes more likely. The Target Plant Concept (TPC) is an effective framework for defining, producing, and handling seedlings and other types of plant material based on specific characteristics suited to a given site. These characteristics are often scientifically derived from testing factors that are linked to outplanting success, such as seedling morphology and physiology, genetic source, and capacity to overcome limiting factors on outplanting sites. This article briefly summarizes the current knowledge drawn from existing literature for each component of the TPC framework, thereby helping land managers and scientists to meet objectives and accelerate reforestation and restoration trajectories.

Testo completoAbstract (sommario):
Reforestation provides restoration of forest ecosystem services including improved soil fertility, which leads to increased productivity and/or sustainability of the system. Trees also increase the average carbon stocks providing wood supply for local communities; however, C sequestration strategies highlight tree plantations without considering their full environmental consequences, such as losses in stream flow. The productivity of a site is a consequence of their physical, chemical, and biological properties, resulting in natural fertile soils or adequate managed soils for improved quality. Thus, it is required to know the variations in the properties of land-use systems for adoptability of agroforestry innovations. The choice of agroforestry tree species (highly mycorrhizal dependent plants should be selected) would have great implications for the manipulation of arbuscular mycorrhizas's species. In dry forest, the inevitable consequence of cutting has been the loss of vegetation cover and insufficient scientific information on the capacity to optimize forest recuperation affects agroforestry adoption. To study the biological properties of soils is now of interest; therefore, this paper reviews the literature that has hitherto been published on mycorrhizal interactions for reforestation and points out the use of mycorrhizal technology as one of the alternatives to improve forest products and environmental quality.

An attempt is made to investigate the consequences of land tenure policy on the environment enhancing reforestation as a means of ascertaining tenure security in the Gambella region. This paper sheds light on the acc elerated pace of deforestation in the study area and its impact on the environment. The theoretical and conceptual issues of the interrelation between reforestation, deforestation, land tenure system, and other socio-economic indicators have been given due attention in the literature review. Research methodology gives much focus on qualitative data analysis that uses ranges of data collection approaches; FGD, KII, semi-structured household interviews with the inclusion of secondary data reviews. The paper considers the effect of land tenure system on the environment and discusses the landholding system in the study area, including customary land rights among the Nuer, the Anywaa, and the Majangir. To this effect, external factors and urban expansions are addressed with the view to understanding the impact of socio-cultural practice on physical environment perception and management. A conclusion and policy implications are also discussed.

The country of Vietnam has long been recognized as an important region for biodiversity (Sterling et al. 2006). High-profile discoveries in the 1990s of many species new to science including large ones such as the Saola (Pseudoryx nghetinhensis), an 85 kg basal member of the cattle subfamily Bovinae and the first new genus of large land-dwelling mammal described since the okapi (Okapia johnstoni) in 1901, have focused the attention of national and international conservation organizations on Vietnam and surrounding countries in mainland Southeast Asia (Hurley et al. in prep.). Conservation action for these endemic, endangered species relies on a clear understanding of trends in habitat conversion. To track deforestation rates through time in Vietnam, Meyfroidt and Lambin (2008) combined remotely sensed data with landscape metrics such as number of patches, mean patch size, mean proximity index, and total core area index. They tested their analyses across a variety of land cover studies including those using Advanced Very High Resolution Radiometer (AVHRR), Landsat, SPOT, and MODIS data sources. They found that forest cover decreased nationally from the 1980s to the 1990s and then showed an increase between 1990 and 2000, due to plantation forests as well as natural forest regeneration. However, the effects of this forest transition on fragmentation metrics noted above differed across the country. For instance, in some places, such as central Vietnam where forest cover is relatively large and well connected, reforestation led to a decrease in forest fragmentation and secondary forests recovered rapidly. However in others, such as areas in the north where forest fragmentation dates back centuries and forests have therefore long been isolated, reforestation did not seem to have an impact on continued fragmentation and habitat loss. In this chapter we detail the importance of fragmentation and landscape metrics to ecology and conservation, outlining when and where remotely sensed data can help in these analyses. We then discuss a subset of fragmentation metrics and point to some challenges in processing fragmentation data. We provide examples of composition and connectivity metrics illuminated with examples from the remote sensing literature.
