Comprehensive evaluation of the climate-change implications of shifting land use between forest and grassland: New Zealand as a case study

Journal Articles & Books
December, 2012
New Zealand

The transition of land between forest and grassland has important implications for greenhouse gas emissions and removals. In this paper, we use New Zealand as a case study to comprehensively assess, compare and quantify the net climate change impact of shifting land use between temperate forest and grassland. Forests store large amounts of carbon in their biomass, whereas grasslands contain relatively little biomass carbon. These biomass changes tend to dominate the carbon balance under land-use change.

importance of land cover change across urban–rural typologies for climate modeling

Journal Articles & Books
December, 2013

Land cover changes affect local surface energy balances by changing the amount of solar energy reflected, the magnitude and duration over which absorbed energy is released as heat, and the amount of energy that is diverted to non-heating fluxes through evaporation. However, such local influences often are only crudely included in climate modeling exercises, if at all. A better understanding of local land conversion dynamics can serve to inform inputs for climate models and increase the role for land use planning in climate management policy.

Habitat loss and human–elephant conflict in Assam, India: does a critical threshold exist?

Journal Articles & Books
December, 2011
India

Human–elephant conflict in India, driven by habitat loss and an expanding human population, is a complex challenge for biodiversity conservation. Determining if, how and why this conflict has changed over time will be an important step towards managing landscapes where people and elephants Elephas maximus coexist. This study combines social surveys and remote sensing data to analyse patterns in human–elephant conflict and land-use change over time.

Agroforestry and the search for alternatives to slash-and-burn cultivation: From technological optimism to a political economy of deforestation

Journal Articles & Books
December, 2009

Launched in 1994, the Alternatives to Slash-and-Burn Programme is a multidisciplinary collaborative research effort aimed at addressing the issue of deforestation. This article analyzes the genesis and the history of this research effort and the causes of its successes and failures. I will show that despite the genuine commitment of the ASB Programme to achieve comprehensive analysis linking the social and the biophysical realms, its conclusions and recommendations were biased in favor of biophysical models whose adoption by farmers remained low.

Can REDD+ Save the Forest? The Role of Payments and Tenure

Journal Articles & Books
September, 2012

A recent policy response to halting global forest deforestation and degradation, and any resulting greenhouse gas emissions is REDD+, which also includes the role of conservation, sustainable management of forests and enhancement of forest carbon stocks. Although still in its infancy, the success of REDD+ will depend significantly on whether it can be economically viable and if any resulting payments are sufficient to cover the opportunity cost plus any transaction cost.

Land use and land cover change in the Colombian Andes: dynamics and future scenarios

Journal Articles & Books
December, 2013

Land use and land cover changes (LUCC) are recognized as one of the most relevant drivers of biodiversity loss in ecosystems. Through the analysis of satellite images, this article quantifies the LUCC that occurred between 1985 and 2008 in the Colombian Andes. Four submodels of changes were analyzed: deforestation, crop intensification, conversion to pastures, and abandonment.

Vegetation change in Brazil’s dryland ecoregions and the relationship to crop production and environmental factors: Cerrado, Caatinga, and Mato Grosso, 2001–2009

Brazil

South America’s drylands remain some of the most threatened ecosystems on the planet. Yet, we know very little about the dynamics of land-use and land-cover change (LUCC) in these understudied regions. Our objective is to map vegetation change in Brazil’s three largest dryland ecoregions – the Cerrado, Caatinga, and Mato Grosso seasonal forests – using MODIS (Moderate Resolution Imaging Spectroradiometer) data from 2001 to 2009 at the scale of the municipality.

Soil-vegetation patterns in secondary slash and burn successions in Central Menabe, Madagascar

Journal Articles & Books
December, 2010
Madagascar

Slash and burn agriculture is a traditional and predominant land use practice in Madagascar and its relevance in the context of forest preservation is significant. At the end of a cycle of culture, the fields become mostly weed covered and the soil fertility starts to drop. As a consequence, these fields are abandoned (they are called “monka”) and the farmers, in the best case, re-use old surfaces where the vegetation has recovered to some extent. Nevertheless, some of the farmers continue to extend part of their cultures into the natural forest.

Land-use/cover dynamics in Northern Afar rangelands, Ethiopia

December, 2010
Ethiopia

This study uses a combination of remote sensing data, field observations and information from local people to analyze the patterns and dynamics of land-use/cover changes for 35 years from 1972 to 2007 in the arid and semi-arid Northern Afar rangelands, Ethiopia. A pixel-based supervised image classification was used to map land-use/cover classes. People's perceptions and ecological time-lines were used to explain the driving forces linked to the changes. A rapid reduction in woodland cover (97%) and grassland cover (88%) took place between 1972 and 2007.

Trans-boundary infrastructure and land cover change: Highway paving and community-level deforestation in a tri-national frontier in the Amazon

Bolivia
Brazil
Peru

Economic globalization manifests in landscapes through regional integration initiatives involving trans-boundary infrastructure. While the relationships of roads, accessibility and land cover are well-understood, they have rarely been considered across borders in national frontier regions. We therefore pursue an analysis of infrastructure connectivity and land cover change in the tri-national frontier of the southwestern Amazon where Bolivia, Brazil and Peru meet, and where the Inter-Oceanic Highway has recently been paved.

Property rights, land conflicts and deforestation in the Eastern Amazon

Journal Articles & Books
December, 2008

In the Brazilian Amazon, insecure property rights are among the main causes of land conflicts and deforestation. Through an in-depth empirical case study in Maranhao in the Eastern Amazon, this research analyzes how distorted agrarian, forest and environmental policies, laws and regulations originated insecure property rights not only over land, but also over timber, which allied to social and political factors, such as uneven distribution of land and strong organization of landless peasants, led to land conflicts and deforestation.

Causes of Deforestation: The Maine Case

Journal Articles & Books
December, 2008

Many of the world's forests are being destroyed at a rapid rate. This article analyzes the decisions of landowners in Maine, where forests have been heavily harvested and much land has been converted to non-forest use. Data on these landowners and their land were obtained from primary and secondary sources, satellite change detection analysis, and structured interviews. We found that there are several different landowner groups making different harvesting decisions in response to different incentives.
