The Land Cover Atlas of the Republic of South Sudan provides information on the land cover distribution by administrative and sub-basin divisions. The dataset was created using the FAO/GLCN methodology and tools. Main data sources include satellite imagery from SPOT and Global Land Survey (GLS) Landsat, existing Africover land cover database and ancillary data.

Land Tenure Working Paper 18. Presents the main themes that characterize the governance in land tenure and analyses the aspects related to the evolution of agricultural policy issues in various Central American countries. It also offers some examples and lessons learned from new models of land administration and land access mechanisms that Central American governments and International Cooperation have fostered over the past fifteen years in the Region.

Land Cover Classification System: Advanced Database Gateway

Journal Articles & Books
Janvier, 2016

Advanced Database Gateway The FAO Land Cover Classification System software is due to be released in its third version, and with it come four supporting volumes. The third volume is a tutorial for the use of the Advanced Database Gateway which allows users to better interact with the LCCS and adapt it to their needs. The FAO LCCS is applicable to commercial use, national security, environmental protection, natural resource management, climate change mitigation and tracking of greenhouse gas emissions; and creates land classifications that are internationally transparent and comparable.

Revealing Regional Deforestation Dynamics in North-Eastern Madagascar—Insights from Multi-Temporal Land Cover Change Analysis

Peer-reviewed publication
Juin, 2015

The north-eastern escarpment of Madagascar harbours the island’s last remaining large-scale humid forest massifs surrounded by a small-scale agricultural mosaic. There is high deforestation, commonly thought to be caused by shifting cultivation practiced by local land users to produce upland rice. However, little is known about the dynamics between forest and shifting cultivation systems at a regional level.

An Initial Assessment of the Economic Value of Coastal and Freshwater Wetlands in West Asia

Peer-reviewed publication
Septembre, 2014

Many countries in West Asia, defined in this study as the Arabic-speaking countries of the Arabian Peninsula plus Turkey and Iran, have enacted environmental conservation laws but regional underlying drivers of environment change, such as rising incomes and fast-growing populations, continue to put pressure on remaining wetlands. This paper aims to inform conservation efforts by presenting the first regional assessment of the economic value of coastal and freshwater wetlands in West Asia.

Historical Landscape Perspectives on Grasslands in Sweden and the Baltic Region

Peer-reviewed publication
Mars, 2014

A landscape perspective is generally recognized as essential for conservation biology. The main underlying reason is that species respond to features of the landscape at various spatial scales, for example habitat area, connectivity, and matrix habitats. However, there is also an “historical” component of a landscape perspective, which has not received similar attention. The underlying reasons for historical effects are that humans have influenced landscapes during several millennia and that species and communities may respond slowly to land use change.

Forest Cover Changes in Lao Tropical Forests: Physical and Socio-Economic Factors are the Most Important Drivers

Peer-reviewed publication
Juin, 2017
Laos

Lao People’s Democratic Republic (PDR) has been experiencing significant forest depletion since the 1980s, but there is little evidence to demonstrate the major causes and underlying drivers for the forest cover changes. In this study, we investigated the relationship between forest cover decrease and increase in the south of Lao PDR between 2006 and 2012 and selected physical and socio-economic factors.

Uncovering Dominant Land-Cover Patterns of Quebec: Representative Landscapes, Spatial Clusters, and Fences

Peer-reviewed publication
Décembre, 2013

Mapping large areas for planning and conservation is a challenge undergoing rapid transformation. For centuries, the creation of broad-extent maps was the near-exclusive domain of expert specialist cartographers, who painstakingly delineated regions of relative homogeneity with respect to a given set of criteria. In the satellite era, it has become possible to rapidly create and update categorizations of Earth’s surface with improved speed and flexibility. Land cover datasets and landscape metrics offer a vast set of information for viewing and quantifying land cover across large areas.

New Cropland on Former Rangeland and Lost Cropland from Urban Development: The “Replacement Land” Debate

Peer-reviewed publication
Septembre, 2014

In this study, a land use/land cover change analysis method was developed to examine patterns of land use/land cover conversions of cropland to urban uses and conversions of rangeland to cropland uses in the United States (US) Midwest region. We used the US 2001 and 2006 National Land Cover Datasets (NLCD) for our spatial analyses of these conversion trends.

“Bring Back the Land”—A Call to Refocus on the Spatial Dimension of Zimbabwe’s Land Reform

Peer-reviewed publication
Juin, 2015
Zimbabwe

In this article, we argue that research on land reform in the nation of Zimbabwe has overlooked possibilities of integrating geospatial methods into analyses and, at the same time, geographers have not adequately developed techniques for this application. Scholars have generally been captured within the debate focused on the success or failure of the Zimbabwean land reform program, and have neglected to analyze what has occurred where during the process of “fast-track land reform”.

“Nothing Is Like It Was Before”: The Dynamics between Land-Use and Land-Cover, and Livelihood Strategies in the Northern Vietnam Borderlands

Peer-reviewed publication
Décembre, 2015

Land uses are changing rapidly in Vietnam’s upland northern borderlands. Regional development platforms such as the Greater Mekong Subregion, state-propelled market integration and reforestation programs, and lowland entrepreneurs and migrants are all impacting this frontier landscape. Drawing on a mixed methods approach using remote sensing data from 2000 to 2009 and ethnographic fieldwork, we examine how land-use and land-cover change (LULCC) has occurred across three borderland provinces—Lai Châu, Lào Cai and Hà Giang—with high proportions of ethnic minority semi-subsistence farmers.

How to Make a Barranco: Modeling Erosion and Land-Use in Mediterranean Landscapes

Peer-reviewed publication
Septembre, 2015
Espagne

We use the hybrid modeling laboratory of the Mediterranean Landscape Dynamics (MedLanD) Project to simulate barranco incision in eastern Spain under different scenarios of natural and human environmental change. We carry out a series of modeling experiments set in the Rio Penaguila valley of northern Alicante Province. The MedLanD Modeling Laboratory (MML) is able to realistically simulate gullying and incision in a multi-dimensional, spatially explicit virtual landscape. We first compare erosion modeled in wooded and denuded landscapes in the absence of human land-use.
