Changes of landscape spatial structure as a result of transformation of land-ownership

Conference Papers & Reports
Dezembro, 2013
Letónia
Lituânia

The aim of the research is to analyse the landscape structure changes from the end of the Soviet times in 1974–1986 until 2005 when market economy existed in Lithuania. The changes of landscape structure were observed in 100 sample areas (squares) each of them having 2.5 km2 area and distributed in different landscape types. The changes in sample areas (squares) with determination of land cover structure transformations were observed using topographic photos and ortophoto images at a scale 1:10 000.

Land privatization and afforestation incentive of rural farms in the Northern Uplands of Vietnam

Journal Articles & Books
Dezembro, 2010
Vietnam

Poverty and deforestation are critical issues in a number of developing countries where the policy framework is in many cases insufficient to provide rural people an incentive to afforest. This paper analyzes both the impact of land privatization on afforestation efforts of rural farm households in the Northern Uplands of Vietnam and the economic incentive of farm households on afforestation efforts. The determinants of afforestation by farm households were analyzed.

Land use changes on the slopes of Mount Elgon and the implications for the occurrence of landslides

Journal Articles & Books
Dezembro, 2012

A reconstruction of land use changes and the implications thereof for landslide occurrence on critical slopes of Mount Elgon in Eastern Uganda were undertaken. Aerial photographs taken in 1960 formed the benchmark for the analysis of respective land use changes between 1995 and 2006, using 30m Landsat TM and 20m SPOT MS images. Landslide sites were mapped using a MobileMapper, and terrain parameters were derived using a 15m Digital Elevation Model.

GIS and the ‘Usual Suspects’-[Mis]understanding Land Use Change in Cambodia

Journal Articles & Books
Dezembro, 2014
Cambodja

GIS-RS techniques offer great potential for providing insights into the spatiality and temporality of the messy realties of deforestation. However, rather than positing that the land use maps produced using these novel technologies can cut through politics, it is argued that the map is merely an artifact of the broader process of land use planning which is constitutive of politics. This article critically reflects on a major land use mapping exercise that the two authors were involved with, in central Cambodia.

Formal institutions and their role in promoting sustainable land management in boteti, botswana

Journal Articles & Books
Dezembro, 2014
Botswana

The aim of this paper is to discuss the role of existing policies, programmes and legislation in promoting sustainable land management and livelihoods in mid‐central Botswana. The paper is based on data from the survey of relevant literature, analysis of policy and legal documents, field observations and a series of stakeholder workshops held in the villages of Mopipi, Mokobaxane and Rakops in Boteti Sub‐District between 2008 and 2009.

Remote sensing of land-use change for Kyoto Protocol reporting: the New Zealand case

Journal Articles & Books
Dezembro, 2012
Nova Zelândia

It is necessary to estimate the area of afforestation and deforestation in New Zealand, since 1990, to meet reporting obligations under the Kyoto Protocol. We describe a method for national mapping of forest change that achieves high accuracy, but only requires moderate effort. A national coverage of satellite imagery is standardised, classified (automatically) for land cover, and then compared with an existing 1990 land-use map to identify polygons (>1ha) of possible forest change. Each one of these possible change polygons is checked by operators for actual or spurious change.

Mediating Forest Transitions: Grand Design or Muddling Through

Journal Articles & Books
Novembro, 2008
Global

Present biodiversity conservation programmes in the remaining extensive forest blocks of the humid trop-ics are failing to achieve outcomes that will be viable in the medium to long term. Too much emphasis is given to what we term grand design-ambitious and idealistic plans for conservation. Such plans im-plicitly oppose or restrict development and often attempt to block it by speculatively establishing paper parks. Insufficient recognition is given to the inevitable long term pressures for conversion to other land uses and to the weakness of local constituencies for conservation.

Uniform global deforestation patterns — An empirical analysis

Journal Articles & Books
Dezembro, 2013

The forest transition (FT) hypothesis implies that changes in a region's forest cover follow a determinable pattern of decline and later re-expansion over time, which is supposed to be similar across regions and countries. Such a uniform pattern – if empirically proven and quantified – might help in establishing REDD+ baselines (i.e., references against which reductions in the emissions from deforestation and forest degradation of developing countries could be measured, and subsequently be rewarded).

Desertification in the Arab Region: analysis of current status and trends

Journal Articles & Books
Dezembro, 2002

The total area of the Arab Region is about 14·2 million km2, 90% of it lies within arid, semi-arid and dry sub-humid areas. The area is characterized by harsh environment, fragile ecosystems and limited water resources and arable lands. Throughout its long history these lands were the main source of grain and animal production. By the end of this century and in spite of the national, regional and international efforts to combat desertification and mitigate the effect of drought and desiccation, desertification is still one of the major environmental problems in the Arab Region.

Influence of carbon mapping and land change modelling on the prediction of carbon emissions from deforestation

Journal Articles & Books
Dezembro, 2012

The implementation of an international programme for reducing carbon emissions from deforestation and degradation (REDD) can help to mitigate climate change and bring numerous benefits to environmental conservation. Information on land change modelling and carbon mapping can contribute to quantify future carbon emissions from deforestation. However limitations in data availability and technical capabilities may constitute an obstacle for countries interested in participating in the REDD programme.

Antibiotic resistance profiles of soil bacterial communities over a land degradation gradient

Tailândia

This study profiled soils over a land degradation gradient to obtain formulae as integrative measures for describing the gradient as a result of deforestation in Thailand. We applied antibiotic resistance most-probable-number profiling to the soil bacterial communities, and then described the gradient. Soil samples were collected on the gradient represented by dry evergreen forest (the original vegetation), dry deciduous forest (moderately disturbed) and bare ground (the most degraded) in February (dry season), March (shortly after temporal precipitation) and June (rainy season) 2001.

International Finance for REDD+ Within the Context of Conservation Financing Instruments

Journal Articles & Books
Dezembro, 2015

Reducing Emissions from Deforestation and forest Degradation (REDD+) is a conservation finance instrument based on the payments for ecosystem services model, wherein governments, private landowners, concession holders, and/or communities are compensated for undertaking activities which mitigate greenhouse gas emissions from forest use and land use change. This article reviews the numerous sources for REDD+ finance within the context of total global conservation finance.
