Patterns and trends in land-use land-cover change research explored using self-organizing map

Journal Articles & Books
December, 2011

Research on land change has a long history, has generated numerous publications and continues to receive international research attention. To facilitate the understanding of the patterns and trends of land-change research, this article uses a content-based text-retrieval approach and self-organizing map to analyse more than 700 peer-reviewed remote-sensing and natural-science papers on land-use/cover change (LUCC) from the past two decades. We present the results in map-like displays and discuss papers within the identified clusters to examine the research activities.

Changing Landscapes for Forest Commons: Linking Land Tenure with Forest Cover Change Following Mexico’s 1992 Agrarian Counter-Reforms

Journal Articles & Books
December, 2013
Mexico

Mexico’s 1992 agrarian counter-reforms opened up the country’s vast network of common property regimes, known as ejidos, to the possibility of privatization. This study investigates the relationship between dynamic common property regimes and deforestation in the wake of policy reform among eight ejidos in southeastern Mexico. Using institutional analyses, land use/land cover change (LULCC) analyses and a Forest Dependency Index, we examine how land tenure arrangements relate to land use and forest cover change patterns.

remote sensing approach to monitor the conservation status of lacustrine Phragmites australis beds

Journal Articles & Books
December, 2013
Italy

Phragmites australis populations in native areas have been gradually declining since the mid-20th century. We developed a logical approach based on remote sensing to monitor the conservation status of P. australis beds in response to environmental gradients and orient future management actions in Lake Garda (northern Italy). During the 2010 growing season we collected data on: (i) the structural and functional status of seven P.

Water Scarcity in the Andes: A Comparison of Local Perceptions and Observed Climate, Land Use and Socioeconomic Changes

Journal Articles & Books
December, 2013
Colombia
South America

In the Andean region of South America, understanding communities’ water perceptions is particularly important for water management as many rural communities must decide by themselves if and how they will protect their micro-watersheds and distribute their water. In this study we examine how Water User Associations in the Eastern Andes of Colombia perceive water scarcity and the relationship between this perception and observed climate, land use, and demographic changes. Results demonstrate a complex relationship between perceptions and observed changes.

Impact of Land-Use Change on Ecosystem Services, Biodiversity and Returns to Landowners: A Case Study in the State of Minnesota

Journal Articles & Books
December, 2011

Land-use change has a significant impact on the world's ecosystems. Changes in the extent and composition of forests, grasslands, wetlands and other ecosystems have large impacts on the provision of ecosystem services, biodiversity conservation and returns to landowners. While the change in private returns to landowners due to land-use change can often be measured, changes in the supply and value of ecosystem services and the provision of biodiversity conservation have been harder to quantify.

Using combined AHP–genetic algorithm in artificial groundwater recharge site selection of Gareh Bygone Plain, Iran

Journal Articles & Books
December, 2014
Iran

Flood spreading is one of the suitable strategies to control and benefit from floods which in turn improve the groundwater recharge, makes soil more fertile, and increases nutrients in soil. It is also a method for reusing sediment, which is usually wasted. Thus, selection of suitable areas for flood spreading and directing the flood water into permeable formations are amongst the most effective strategies in flood spreading projects.

Deforestation and the Environmental Kuznets Curve in Iran

Journal Articles & Books
December, 2014
Iran

Property rights, the agricultural price index, forest area, population, income and timber price are important factors in the deforestation process. The aim of this study was to test the impact of these factors on deforestation in Iran using an environmental Kuznets curve (EKC). The autoregressive distributed lag approach was also used to estimate the deforestation function. The existence of an inverted U-shaped EKC for deforestation in Iran was confirmed.

Combining pedometrics, remote sensing and field observations for assessing soil loss in challenging drylands: A case study of Northwestern Somalia

Journal Articles & Books
December, 2009
Somalia

Soil loss is a major concern for land managers due to its influence on biomass production, surface water quality and landscape beauty. In Somalia, the risk of soil loss is accelerated by the removal of vegetation, bad land use practices and negative impacts of urbanization. The political upheavals and consequent insecurity in the country are major limitations for detailed database and research in soil loss.

AN AGENDA FOR THE STUDY OF LAND USE, WILDERNESS DESIGNATION, AND RESOURCE REGULATION IN THE AMERICAN WEST

Policy Papers & Briefs
December, 1995

Atemporal and intertemporal use of public lands, the determination of optimal levels of wilderness designation and habitat preservation, and the appropriate regulation of natural resources have all been "hot button" issues in the American West for quite some time now. In this paper, I propose and describe a research agenda which promises to yield interesting and useful new policy insights into these fractious resource issues.

Developing REDD+ policies and measures from the bottom-up for the buffer zones of Amazonian protected areas

Journal Articles & Books
December, 2012
Peru

A key activity in Phase 1 of REDD+—the UN’s Framework Convention on Climate Change (UNFCCC) forestry mitigation mechanism—is the development of policies and measures (PAMs) to define where and how emissions reductions and carbon stock enhancements and conservation will be achieved. This paper provides contextual data and information for the development of PAMs specifically for the buffer zones of protected areas in the Peruvian Amazon, sites where REDD+ has the potential to generate considerable social and ecological co-benefits.

Spatial driving forces of dominant land use/land cover transformations in the Dongjiang River watershed, Southern China

Journal Articles & Books
December, 2016

Information about changes in, and causes of, land use/land cover (LULC) is crucial for land use resource planning. We investigated the processes involved in LULC change (LUCC) in the Dongjiang Watershed, in Southern China, over a 15-year period to gain a better understanding of the causes of the main types of LUCC. Using a depth transition matrix and redundancy analysis (RDA), the major types and causes of LUCC for each LULC type over the past 15 years were identified. LUCC exhibited obvious net change, relatively low persistence, and high swap change.
