Prediction of Land Cover Change Using Markov and Cellular Automata Models: Case of Al-Ain, UAE, 1992-2030

Journal Articles & Books
Dezembro, 2014

The UAE has witnessed rapid urban development and economic growth in recent years. With its ambitious vision to become one of the advanced nations by 2021, planners and policy-makers need to know the most likely direction of future urban development. In this study, remotely sensed imagery coupled with cellular automata models were used to predict land cover in Al Ain, the second largest city in the Emirate of Abu Dhabi. Markov and cellular automata models were used for 1992 and 2006 to predict land cover in 2012.

Automated Approach for Land Cover Classification Based on a Fuzzy Supervised Learning Framework

Journal Articles & Books
Dezembro, 2014

This paper proposes an automatic framework for land cover classification. In majority of published work by various researchers so far, most of the methods need manually mark the label of land cover types. In the proposed framework, all the information, like land cover types and their features, is defined as prior knowledge achieved from land use maps, topographic data, texture data, vegetation’s growth cycle and field data.

Local knowledge and management of simpukng (forest gardens) among the Dayak people in East Kalimantan, Indonesia

Indonésia

Among the Dayak people in East Kalimantan, simpukng (“forest gardens”) are an important component of their traditional farming systems. Simpukng is managed secondary forests in which selected species of fruits, rattan, bamboo, timber and other plants are planted. While most are owned by families and passed down from one generation to the next, some are managed on a communal basis. Complex customary Dayak rules exist that control the use and inheritance of these forests that help to avoid over-exploitation of resources.

Assessment of Beetle and Bug Diversity in Extensively Managed Cattle Farms of Varying Cattle Density, Sward Height, and Surrounding Land Use

Journal Articles & Books
Dezembro, 2015

Livestock that is extensively managed can have higher diversity and abundance of insects in comparison to intensively managed livestock, although data are more equivocal within a gradient of extensively managed pastures. Additionally, biodiversity on farms is vulnerable to degradation of the surrounding landscape and changing patterns of land use. We monitored Coleoptera and Hemiptera on grass-fed cattle farms in North Carolina to determine effects of cattle and land use patterns on biodiversity.

Impact of rainwater harvesting on water resources of the modder river basin, central region of South Africa

Along the path of water flowing in a river basin are many water-related human interventions that modify the natural systems. Rainwater harvesting is one such intervention that involves collecting and use of surface runoff for different purpose in the upstream catchment. Increased water consumption at upstream level is an issue of concern for downstream water availability to sustain ecosystem services.

Forest land transformation in Latvia: resume of the PhD paper for the scientific degree of Dr.silv. in Forest Economic and Policy

Dezembro, 2008
Letónia

The Promotional Paper Forest Land Transformation in Latvia by Gunta Bāra has been developed at the Forest Faculty of the Latvian University of Agriculture between 2001 and 2007. Goal of the Promotional Paper: to identify the main problems in transformation of forest land in the Republic of Latvia and gaps in legislative instruments regulating the process of change of land use type, to prepare recommendations for their elimination, to develop a methodology for calculation of compensation for the losses caused to the state as a result of destruction of natural forest environment.

impact of land use on woody plant cover and species composition on the Grahamstown municipal commonage: implications for South Africa's land reform programme

Using an analysis of aerial photographs from 1942, 1985 and 2004 we assessed the impact of changing land tenure and land-use regimes on the cover of thicket vegetation on the Grahamstown commonage. Land-use impacts were examined by comparing plant species composition within three vegetation types between sites incorporated into commonage for different lengths of time and sites outside the commonage. Results showed that thicket cover increased by 87% between 1942 and 1985 but declined by 11% between 1985 and 2004.

Co-kriging for modeling shallow groundwater level changes in consideration of land use/land cover pattern

Japão

This study aimed at clarifying the relationship between the dynamics of land use/land cover (LULC) changes and decline in the groundwater levels, and specifying an LULC category strongly affecting such decline in a Quaternary sedimentary basin. Groundwater level data recorded at 26 observation wells for a 14-year period in the Kumamoto Plain, central Kyushu, southwest Japan, were used for the analysis. The general trends of LULC were detected by a satellite image classification technique and surface spline method, which highlighted the decreases in groundwater-recharge materials.

Sphagnum re-introduction in degraded peatlands: The effects of aggregation, species identity and water table

In European peatlands which have been drained and cut-over in the past, re-vegetation often stagnates after the return of a species-poor Sphagnum community. Re-introduction of currently absent species may be a useful tool to restore a typical, and more diverse, Sphagnum vegetation and may ultimately improve the functioning of peatland ecosystems, regarding atmospheric carbon sequestration. Yet, the factors controlling the success of re-introduction are unclear. In Ireland and Estonia, we transplanted small and large aggregates of three Sphagnum species into existing vegetation.

Complex effects of fragmentation on remnant woodland plant communities of a rapidly urbanizing biodiversity hotspot

Journal Articles & Books
Dezembro, 2014

In many cities worldwide, urbanization is leading to the rapid and extensive fragmentation of native vegetation into small and scattered urban remnants. We investigated the effects of fragmentation on plant species richness and abundance in 30 remnant Banksia woodlands in the rapidly expanding city of Perth, located in the southwestern Australian global biodiversity hotspot.

Factors influencing large wildland fire suppression expenditures

Journal Articles & Books
Dezembro, 2008

There is an urgent and immediate need to address the excessive cost of large fires. Here, we studied large wildland fire suppression expenditures by the US Department of Agriculture Forest Service. Among 16 potential non-managerial factors, which represented fire size and shape, private properties, public land attributes, forest and fuel conditions, and geographic settings, we found only fire size and private land had a strong effect on suppression expenditures. When both were accounted for, all the other variables had no significant effect.
