Naturalitatea pădurii: concepte, caracteristici și implicații asupra conservării

Journal Articles & Books
декабря, 2014

The paper review the naturalness related concepts, with a special emphasis on forests, and also their implications on forest conservation. Beside naturalness, key aspects of wild(er)ness, ecosystem integrity, ecosystem health, forest quality and authenticity are disscussed. The main approaches on forest naturalness are presented, including the basic (minimum) naturalness requests, the shortcomings of associating high extreme naturalness levels (virgin, pristine) to forests, or the necessity to consider the temporal component of naturalness (e.g. the forest history).

Underutilized wild edible plants in the Chilga District, northwestern Ethiopia: focus on wild woody plants

Ethiopia

BACKGROUND: Ethiopia encompasses an extraordinary number of ecological zones and plant diversity. However, the diversity of plants is highly threatened due to lack of institutional capacity, population pressure, land degradation and deforestation. An adequate documentation of these plants also has not been conducted. The farmers in Ethiopia face serious and growing food insecurity caused by drought, land degradation and climate change. Thus, rural communities are dependent on underutilized wild edible plants to meet their food and nutritional needs.

Migrants, land markets and carbon emissions in Jambi, Indonesia: Land tenure change and the prospect of emission reduction

Indonesia

Policies designed to reduce land-based carbon emissions require a good understanding of the complex connections between state-sanctioned concessions, forest conversion, informal land markets and migrants. Our case study in the peat forests of the Tanjung Jabung Barat (TanJaBar) regency of Jambi, Indonesia aimed to explore relations between four key stakeholder groups: the state, local communities, migrants, and state-sanctioned concessions.

Implications of uncertainty and scale in carbon emission estimates on locally appropriate designs to reduce emissions from deforestation and degradation (REDD+)

Journal Articles & Books
декабря, 2014
Indonesia

This study combined uncertainty analysis of carbon emissions with local stakeholders' perspectives to develop an effective Reducing Emission from Deforestation and Degradation (REDD+) scheme at the district level. Uncertainty of carbon emission estimates depends on scale while local stakeholders' views on plausible REDD+ schemes influence and limit transaction costs. The uncertainty analysis formed the basis for determining an appropriate scale for monitoring carbon emission estimates as performance measures for REDD+ incentives.

Reform or reversal: the impact of REDD+ readiness on forest governance in Indonesia

Journal Articles & Books
декабря, 2014
Indonesia

Indonesia has turned its alleged role as global leader of land-based carbon emissions into a role as a global trailblazer exploring modalities for Reducing Emissions from Deforestation and Forest Degradation (REDD+). REDD+ readiness is largely about improving forest governance, but this itself is a multilayered concept. This article analyses how the processes and practices of REDD+ readiness are leading to various forest governance reforms in Indonesia.

Forest ecosystem services and biodiversity in contrasting Himalayan forest management systems

Journal Articles & Books
декабря, 2014

In developing countries, the landscape surrounding agricultural land is important for maintaining biodiversity and providing ecosystem services. Forests provide a full suite of goods and services to subsistence farmers in the Himalayan agro-ecological system. The effects of biomass outtake on woody species richness and composition were analysed in forests under communal and government management. Interviews on forest use and perception of forest condition and ecosystem service delivery were conducted in farmer households bordering the forests.

Effect of catchment properties on runoff coefficient in a karst area of southwest China

China

Frequent human activities and climate change in the karst region of southwest China since the 1950s have led to the investigation of response of runoff to climate and catchment properties. Runoff coefficient (Rc) as an expression variable of the catchment response to rainfall is important to describe runoff dynamics and to estimate available streamflow for utilization. In this study, the equations of Rc associated with its attributors of climate condition and catchment property were derived using the Budyko framework.

Improving the efficiency measurements of the forest land using the methods of satellite and terrestrial geodesy

Journal Articles & Books
декабря, 2014

Currently the most common methods in forestry mapping includes digital photogrammetry, positioning points system using Global Navigation Satellite Systems (GNSS), or a combination of polar method using universal surveying stations. Due to the fact the forest environment its specific conditions – cover stand, complex terrain in many cases the use of these methods in forestry surveying practice to some extent limited.

Forest Grabbing Through Forest Concession Practices: The Case of Guyana

Journal Articles & Books

Guyana

Colonial governments asserted sovereignty and property rights gradually over the territory of Guyana, disregarding preexisting Indigenous Rights. Although a Forest Department modeled on the Indian Forest Service was established, there was no equivalent settlement process to determine the rights of forest peoples. State Forest area is declared by administrative fiat. These two elements have enabled State-endorsed forestland grabbing. Logging was scattered and selective until the early 1980s.

Rapid deforestation threatens mid‐elevational endemic birds but climate change is most important at higher elevations

Indonesia

AIM: Deforestation and climate change are two of the most serious threats to tropical birds. Here, we combine fine‐scale climatic and dynamic land cover models to forecast species vulnerability in rain forest habitats. LOCATION: Sulawesi, Indonesia. METHODS: We sampled bird communities on four mountains across three seasons in Lore Lindu National Park, Sulawesi, Indonesia (a globally important hotspot of avian endemism), to characterize relationships between elevation and abundance. Deforestation from 2000 to 2010 was quantified, and predictors of deforestation were identified.

Land cover changes in the Lachuá region, Guatemala: patterns, proximate causes, and underlying driving forces over the last 50� years

Guatemala

Identifying the patterns of land cover change (LCC) and their main proximate causes and underlying driving forces in tropical rainforests is an urgent task for designing adequate management and conservation policies. The Lachuá region maintains the largest lowland rainforest remnant in Guatemala, but it has been highly deforested and fragmented during the last decades. This is the first paper to describe the patterns of LCC and the associated political and socioeconomic factors in the region over the last 50� years.

Increasing tree cover while losing diverse natural forests in tropical Hainan, China

China

To protect biodiversity and improve environmental conditions, China has invested billions of dollars in reforestation and payments for ecosystem service programs. Here, we examine the Sloping Land Conversion Program, the largest such program in the world and found that after 13� years of implementation at our study site, it has had negative impacts on natural tropical forests. GIS and remote sensing techniques revealed that both natural forests and natural shrub and grasslands were replaced by non-native monocultural plantations on Hainan Island, China, a key tropical biodiversity hotspot.
