Intersections of Climate Change Mitigation Policies, Land Grabbing and Conflict in a Fragile State: Insights from Cambodia

Policy Papers & Briefs
december, 2015
Cambodia

Thirty years after Cambodia’s ‘democratization’ by the United Nations Transitional Authority (UNTAC), the transition to a market-based economy is raging at full steam. Democracy remains elusive, but policy interventions from Cambodia’s “development partners” color the political, social, and environmental landscapes. This paper attends to the land grabs characteristic of market transitions and to the climate change mitigation strategies currently enhancing conflicts over land and resources in contemporary Cambodia.

A tale of two villages: An investigation of conservation-driven land tenure reform in a Cambodian Protection Forest

december, 2015
Cambodia

In this paper, we present an analysis of the change in household land use following a conservation-driven process of indigenous land titling reform in a Cambodian protected area. In each of the two study villages, we investigated how household land use had changed and the extent of compliance with both legal boundaries of titled areas and community regulations created to govern land use within these areas. A comparison of current household land holdings in each village with those at the start of the tenure reform process indicated a significant increase in household land holdings.

Towards a Spatial Understanding of Trade-Offs in Sustainable Development: A Meso-Scale Analysis of the Nexus between Land Use, Poverty, and Environment in the Lao PDR

Laos

In land systems, equitably managing trade-offs between planetary boundaries and human development needs represents a grand challenge in sustainability oriented initiatives. Informing such initiatives requires knowledge about the nexus between land use, poverty, and environment. This paper presents results from Lao PDR, where we combined nationwide spatial data on land use types and the environmental state of landscapes with village-level poverty indicators. Our analysis reveals two general but contrasting trends.

ACTION LEVERS FOR A SUSTAINABLE FARMLAND MANAGEMENT IN NIGER

Niger

This study aims to contribute to the understanding of factors influencing the sustainable farmland management in Niger. Specifically, it examines the determinants of adoption of sustainable land management practices including measures to combat erosion, and the use of manure, residues and fertilizer with a view to support the formulation of efficient land use policies based on evidences given fact that the impact of factors influencing farmland management appears to be specific to each context.

Restoring aboveground carbon and biodiversity: a case study from the Nile basin, Ethiopia

Journal Articles & Books

Ethiopia

In Ethiopia, exclosures in landscapes have become increasingly important to improving ecosystem services and reversing biodiversity losses. The present study was conducted in Gomit watershed, northern Ethiopia, to: (i) investigate the changes in vegetation composition, diversity and aboveground biomass and carbon following the establishment of exclosures; and (ii) analyse the economic returns of aboveground carbon sequestration and assess the perception of local communities on land degradation and exclosures.

Evaluation of land desertification from 1990 to 2010 and its causes in Ebinur Lake region, Xinjiang China

China

Desertification is a threat to human survival and has a major sustainability development impact on environment and socio-economic society. The study area where oasis desertification occurred is located east of the Ebinur Lake region, just west of Junggar Basin in Xinjiang, China. The ecological and environmental issues in the study area are vulnerable and sensitive. The authors of this paper discuss the changes in land desertification that occurred between 1990 and 2010.

Windstorm disturbance effects on mountain stream ecosystems and the Plecoptera assemblages

Journal Articles & Books
december, 2015

Within the investigated river basins the deforestation ranged from 0-45.5%, dependent on the amount of windstorm damage. Our water temperature readings revealed that the canopy elimination above the streams in the areas damaged by the windstorm caused increase in daily and annual water temperature and also wider daily water temperature range, than those in the undisturbed reference stream, which caused the decline of cold stenotherm species abundance. The stream basins deforestation was collinear with FPOM and UFPOM concentrations, water temperature gradient and nitrate concentrations.

Estimating soil erosion in sub-Saharan Africa based on landscape similarity mapping and using the revised universal soil loss equation (RUSLE)

Journal Articles & Books
december, 2015
Africa

Soil erosion is one of the major forms of land degradation in sub-Saharan Africa (SSA) with serious impact on agricultural productivity. Due to the absence of reliable data at appropriate resolution and differences in the methods used, there are discrepancies in soil erosion estimates at both continental and basin levels. This study attempts to contribute to the existing regional soil erosion estimates based on a two-stage approach.

Role of Forest Income in Rural Household Livelihoods: The Case of Village Common Forest Communities in the Chittagong Hill Tracts, Bangladesh

Journal Articles & Books

Bangladesh

Forests play an important role in the livelihoods of ethnic communities living in the south-eastern region, the Chittagong Hill Tracts (CHTs), of Bangladesh. Over decades, deforestation and land degradation have markedly affected ethnic peoples’ livelihoods in the CHTs. Although communities once managed extensive forest commons to support their livelihood needs, population explosion triggered fragmentation of common land leading to a gradual decline in livelihood opportunities.

Assessing the impact of urbanization on net primary productivity using multi-scale remote sensing data: a case study of Xuzhou, China

december, 2015
China

An improved Carnegie Ames Stanford Approach (CASA) model based on two kinds of remote sensing (RS) data, Landsat Enhanced Thematic Mapper Plus (ETM +) and Moderate Resolution Imaging Spectro-radiometer (MODIS), and climate variables were applied to estimate the Net Primary Productivity (NPP) of Xuzhou in June of each year from 2001 to 2010. The NPP of the study area decreased as the spatial scale increased. The average NPP of terrestrial vegetation in Xuzhou showed a decreasing trend in recent years, likely due to changes in climate and environment.

Land degradation dynamic in the first decade of twenty-first century in the Beijing–Tianjin dust and sandstorm source region

Journal Articles & Books
december, 2015

Land degradation dynamic assessment is very important to understand the effectiveness of ecological engineering and provide decision support for future restorations. Taking the Beijing–Tianjin dust and sandstorm source region (BTSSR) as the study area, the land degradation dynamic in the first decade of twenty-first century is assessed by utilizing the time series trends of net primary production (NPP) and modified rain use efficiency (RUE), respectively, and their sensitivities and performances are evaluated through the validation.

Effects of land cover conversion on soil properties and soil microbial activity in an alpine meadow on the Tibetan Plateau

Land cover conversion intensively occurred in the Tibetan Plateau of China during the past decades. However, responses of soil properties and soil microbial activities to land cover conversion under different land cover types have not been fully understood. The objective was to assess the effects of land cover conversion on soil C and N stocks and soil microbial properties of topsoil of an alpine meadow in the Tibetan Plateau. Soil cores of surface soil (0–20 cm) were collected from three adjacent land cover types: native alpine meadow, artificial grassland and mound-shaped denuded land.
