Holocene land-cover reconstructions for studies on land cover-climate feedbacks [PDF]

open access: yesClimate of the Past, 2010
The major objectives of this paper are: (1) to review the pros and cons of the scenarios of past anthropogenic land cover change (ALCC) developed during the last ten years, (2) to discuss issues related to pollen-based reconstruction of the past land ...

The Standardization and Harmonization of Land Cover Classification Systems towards Harmonized Datasets: A Review

open access: yesISPRS International Journal of Geo-Information, 2017
A number of national, regional and global land cover classification systems have been developed to meet specific user requirements for land cover mapping exercises, independent of scale, nomenclature and quality.

Development of scenarios for land cover, population density, impervious cover, and conservation in New Hampshire, 2010–2100 [PDF]

open access: yes, 2017
Future changes in ecosystem services will depend heavily on changes in land cover and land use, which, in turn, are shaped by human activities. Given the challenges of predicting long-term changes in human behaviors and activities, scenarios provide a ...

High resolution analysis of tropical forest fragmentation and its impact on the global carbon cycle

open access: yesNature Communications, 2017
Vast quantities of carbon stored in tropical forests are threatened by deforestation. Here, using high resolution satellite data, Brincket al. examine how edge effects influence carbon emissions and they find an additional 10.3 Gt of carbon are released ...

CA MARKOV MODELING OF LAND USE LAND COVER DYNAMICS AND SENSITIVITY ANALYSIS TO IDENTIFY SENSITIVE PARAMETER(S) [PDF]

open access: yesThe International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2019
An attempt has been made to explore, evaluate and identify the sensitive parameter(s) of Cellular Automata Markov chain modeling to monitor and predict the future land use land cover pattern scenario in a part of Brahmaputra River Basin, India.

Anthropization processes and protection of the environment: an assessment of land cover changes in Sardinia, Italy [PDF]

open access: yes, 2017
Protection of the environment is implemented through preventive and mitigating measures aimed at hindering anthropization processes. These measures may possibly entail the establishment of natural protected areas and sites where conservation measures are

An International Library for Land Cover Legends: The Land Cover Legend Registry

open access: yesLand, 2022
Information on land cover is vital to numerous United Nations (UN) missions, including achieving the Sustainable Development Goals (SDGs). Because land cover data are developed by a variety of organizations for a range of objectives, they are based on ...

Changes in land cover, rainfall and stream flow in Upper Gilgel Abbay catchment, Blue Nile basin – Ethiopia [PDF]

open access: yes, 2011
In this study we evaluated changes in land cover and rainfall in the Upper Gilgel Abbay catchment in the Upper Blue Nile basin and how changes affected stream flow in terms of annual flow, high flows and low flows.

Modelling Spatial Compositional Data: Reconstructions of past land cover and uncertainties [PDF]

open access: yes, 2017
In this paper, we construct a hierarchical model for spatial compositional data, which is used to reconstruct past land-cover compositions (in terms of coniferous forest, broadleaved forest, and unforested/open land) for five time periods during the past
