Effects of land use patterns on stream water quality: a case study of a small-scale watershed in the Three Gorges Reservoir Area, China

China

In this study, we have considered the relationship between the spatial configuration of land use and water quality in the Three Gorges Reservoir Area. Using land use types, landscape metrics, and long-term water quality data, as well as statistical and spatial analysis, we determined that most water quality parameters were negatively correlated with non-wood forest and urban areas but were strongly positively correlated with the proportion of forest area.

comparison of scenarios for rural development planning and conservation in the Democratic Republic of the Congo

Including a diverse set of stakeholders in collaborative land use planning processes is facilitated by data and maps that communicate and inform an array of possible planning options and potential scenarios of future land use change. In northern Democratic Republic of the Congo (DRC), the African Wildlife Foundation (AWF) has engaged stakeholders and the DRC Government to lead a participatory zoning process in the Maringa–Lopori–Wamba (MLW) Landscape.

Long-term progress in water quality after grassing and fertilization reduction in spring areas of the Sumava Mountains

Policy Papers & Briefs
Julho, 2008
República Checa

The changes in water quality caused by grassing of arable land followed by the reduction in the use of fertilisers after 1989 are demonstrated on an example of two tile-drained subcatchments in spring areas in the Sumava Mountains. The original water quality monitoring was performed in the mid-1980s, at the time when the area was used as tile-drained arable land. The monitoring was renewed in 2004 under different, i.e. extensive, land use conditions.

Theoretical issues of complex organization of use of lands contaminated by radioactive elements

Policy Papers & Briefs

Bielorrússia

In the conditions of the Republic of Belarus there was presents an organization of agricultural use of lands contaminated by radioactive elements. There were shown theoretical bases of the main problems forming the components of a complex project of intra-farm land usage.

Organic Agriculture Supports Biodiversity and Sustainable Food Production

Journal Articles & Books
Dezembro, 2011

Biodiversity is vital to several important ecosystem services that ensure sustainability of food production. In organic agriculture, land management practices that promote biodiversity and soil quality are emphasized and the goal is to maintain a sustainable agricultural system. Soil quality or soil health is the foundation for all agriculture and natural plant communities and a primary indicator of sustainable land management. Soil quality is affected by farm management and land use decisions.

Challenges and opportunities in linking carbon sequestration, livelihoods and ecosystem service provision in drylands

Journal Articles & Books

África

Changes in land use and management practices to store and sequester carbon are becoming integral to global efforts that both address climate change and alleviate poverty. Knowledge and evidence gaps nevertheless abound. This paper analyses the most pressing deficiencies in understanding carbon storage in both soils and above ground biomass and the related social and economic challenges associated with carbon sequestration projects.

mass-balance study on chloride fluxes in a large central European catchment during 1900–2010

República Checa

Using data on long-term monitoring of water quality, mass budgets, and empirical models, we quantified chloride (Cl) leaching from major diffuse and point sources in a large central European catchment (upper Vltava river, Czech Republic) over a 110-year period (1900–2010), with the major aim to evaluate the influence of historical changes in land use and management practices on Cl leaching from agricultural land.

The carbon budget that was derived from forest land use has been extensively explored in most regions/countries of the Northern Hemisphere but is poorly documented in Central Asia. In this study, we proposed a localized bookkeeping model and estimated the sources and sinks of carbon from forest land use and managements between 1961 and 2010 in two arid regions of Central Asia, e.g., Kazakhstan and Xinjiang, China. The results indicate that the forest land use in these two regions acted as a carbon sink, with a total carbon sequestration of 43.27Tg and 20.74Tg respectively.

Underground mining hazard map including building site categories in an area affected by underground mining activities

Journal Articles & Books
Dezembro, 2014
República Checa

The objective of the paper is generation of an underground mining hazard map. The method applied to create the map is based on five categories of areas with different characters of underground mining influence making use of the so-called building site categories. The individual areas with different groups represent various suitability or unsuitability for founding new structures in such influenced territories. They will also reflect a higher or lower degree of influence on already existing structures.

Integrating stream bioassessment and landscape ecology as a tool for land use planning

1. Bioassessment has evolved significantly from a method of deciding whether an ecosystem exposed to stressors should 'pass' or 'fail' (or how badly it fails). Society wants some notion of what has caused any observed degradation of ecosystems, and what management strategies might improve degraded ecosystems. Managers also want to predict what negative or positive effects different land use strategies will have on the component ecosystems of a landscape, including lakes and streams. 2.

Evaluation and Hotspots Identification of Shallow Groundwater Contamination Risk in the Lower Reaches of the Liaohe River Plain

Journal Articles & Books
Dezembro, 2016

As a prerequisite for groundwater protection and contamination control, evaluation of groundwater contamination risk was the extension of groundwater vulnerability assessment. Based on disaster theory and using shallow groundwater of the lower reaches of Liaohe River Plain as the study area, we built an evaluation index system and a contamination index model for groundwater contamination risks from the perspectives of intrinsic vulnerability, external stresses, and functional value.
