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

Journal Articles & Books
Dezembro, 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.

Representing ecological processes in agent-based models of land use and cover change

Journal Articles & Books
Dezembro, 2013

Agent-based models of land use and cover change (ABMs/LUCC) have traditionally represented land-use and land-cover changes as arising from social, economic and demographic conditions, while spatial ecological models have tended to simulate the environmental impacts of spatially aggregated human decisions.

Meta-analysis for the transfer of economic benefits of ecosystem services provided by wetlands within two watersheds in Quebec, Canada

Climate change will cause major changes in ecosystems. Therefore, it is crucial that climate change policy consider the value of all services that are provided by watershed ecosystems. For this purpose, geospatial data and economic analysis are combined to determine a monetary value for wetland ecosystem goods and services (EGSs) in the watersheds of the Yamaska and Bécancour Rivers (Quebec, Canada). From published studies of wetland economic evaluations, we selected 51 relevant studies from 21 countries and performed a benefit transfer using meta-analysis.

Realistic Assessment of the Indicator Potential of Butterflies and Other Charismatic Taxonomic Groups

Journal Articles & Books
Dezembro, 2009

Charismatic groups of animals and plants often are proposed as sentinels of environmental status and trends. Nevertheless, many claims that a certain taxonomic group can provide more-general information on environmental quality are not evaluated critically. To address several of the many definitions of indicator species, we used butterflies to explore in some detail the attributes that affect implementation of indicators generically.

Evaluation of dynamic linkages between evapotranspiration and land-use/land-cover changes with Landsat TM and ETM+ data

Journal Articles & Books
Dezembro, 2012
China

Complexity embedded in coastal management leads to numerous questions as to how inherent spatial and temporal linkages among evapotranspiration (ET), depth to groundwater and land-use/land-cover change (LUCC) could affect the dynamics among these seemingly unrelated events. This article aims to address such unique dynamics in the nexus of physical geography and ecohydrology.

Organic matter fraction and pools of phosphorus as indicators of the impact of land use in the Amazonian periphery

Journal Articles & Books
Dezembro, 2013

The unsustainable use of the soil of the deforested area at the Amazonian border is one of the greatest threats to the rainforest. Among the causes of land degradation in the humid tropics are phosphorus depletion (P), the decrease of soil organic matter (SOM) and the loss of basic cations.

Woody Debris Amendment Enhances Reclamation after Oil Sands Mining in Alberta, Canada

Journal Articles & Books
Dezembro, 2014
Canadá

Mining disturbs large forested areas around the world, including boreal forests after oil sands mining in Canada. Industrial companies are expected to reclaim degraded land to ecosystems with equivalent land capability. This research showed the value of woody debris for reclamation of dramatically disturbed landscapes with a forest ecosystem end land use. Adding woody debris during reclamation can facilitate recovery of flora, soil nutrient cycling and water and nutrient holding capacity.

Landowner response to policies regulating land improvements in Finland: Lease or search for other options?

Journal Articles & Books
Dezembro, 2012
Finlândia

Land improvements with long pay-back periods are often delayed on leased agricultural land. The delay in improvements has been found to result in land degradation, decreased land productivity and environmental problems. An important question is thus how landowners would respond to regulations and mandates concerning land improvements. Based on a Finnish landowner survey, we analysed landowner choices under certain land improvement regulations, using the currently dominant choice of leasing land for agricultural use as the benchmark.
