Human behavioral impact on nitrogen flow--A case study of the rural areas of the middle and lower reaches of the Changjiang River, China

Journal Articles & Books
Diciembre, 2008
China

To assess sustainability of rural management in the Changjiang River basin, human behavioral (food consumption, lifestyle pattern, and human waste disposal) impact on nitrogen flow was quantitatively evaluated. A survey of day-to-day activities was conducted in two representative counties: Taoyuan and Taihe. Daily nitrogen intake from food per capita and potential nitrogen load from human waste on the environment were calculated. The former in Taoyuan and Taihe was 17.0 and 16.0gN, respectively.

Effects of seed mixture and management on beetle assemblages of arable field margins

Journal Articles & Books
Diciembre, 2008

Beetle assemblages and their response to plant community composition and architectural structure were monitored from 2002 to 2006 within arable field margins. Field margins were sown with either tussock grass and forbs, fine grass and forbs or grass only seed mixtures. After an establishment year, field margins were managed using standard sward cuts, scarification, or graminicide application. For predatory beetles, overall density was greatest where tussock grasses were included within the seed mixtures, while the densities of phytophagous beetles were greatest where forbs were present.

Validation of plant diversity indicators in semi-natural grasslands

Journal Articles & Books
Diciembre, 2008
Suecia

The use of plant biodiversity indicators in a nationwide survey of semi-natural grasslands in Sweden was examined by comparing results from the survey with additional in-depth studies of plant diversity at the same 30 sites in southern Sweden. Additional grasslands, that were not subjected to the nationwide survey (i.e. rejected after an initial site selection), were also investigated in order to examine the quality of the initial site selection and to assess to what extent they harboured species rich plant communities.

An evaluation of Side-Manavgat coastal land uses with respect to coastal planning and management

Policy Papers & Briefs
Diciembre, 2009
Turquía

The increase of coastal problems as a result of rapid developments and changes brought new planning and management needs into the agenda. The Integrated Coastal Area Management (ICAM) concept developed under the Mediterranean Action Plan (MAP) includes solutions towards the sustainable use of coastal areas in the Mediterranean Region. Antalya is the province of Turkey with the longest coastline on the Mediterranean Sea. Side- Manavgat coasts of the province are privileged areas with their natural beaches, sand dune forests, rivers and natural and historical relic sites.

Assessing impacts of Roads: Application of a Standard Assessment Protocol

Journal Articles & Books
Diciembre, 2013
Estados Unidos de América

Adaptive management of road networks depends on timely data that accurately reflect the impacts of network impacts on ecosystem processes and associated services. In the absence of reliable data, land managers are left with little more than observations and perceptions to support adaptive management of road-associated disturbances. Roads can negatively impact the soil, hydrologic, plant, and animal processes on which virtually all ecosystem services depend.

Long‐term effects of tillage, nutrient application and crop rotation on soil organic matter quality assessed by NMR spectroscopy

Journal Articles & Books
Diciembre, 2015
Noruega

Crop and land management practices affect both the quality and quantity of soil organic matter (SOM) and hence are driving forces for soil organic carbon (SOC) sequestration. The objective of this study was to assess the long‐term effects of tillage, fertilizer application and crop rotation on SOC in an agricultural area of southern Norway, where a soil fertility and crop rotation experiment was initiated in 1953 and a second experiment on tillage practices was initiated in 1983.

Testing DAYCENT Model Simulations of Corn Yields and Nitrous Oxide Emissions in Irrigated Tillage Systems in Colorado

Journal Articles & Books
Diciembre, 2008
Estados Unidos de América

Agricultural soils are responsible for the majority of nitrous oxide (N2O) emissions in the USA. Irrigated cropping, particularly in the western USA, is an important source of N2O emissions. However, the impacts of tillage intensity and N fertilizer amount and type have not been extensively studied for irrigated systems. The DAYCENT biogeochemical model was tested using N2O, crop yield, soil N and C, and other data collected from irrigated cropping systems in northeastern Colorado during 2002 to 2006.

Assessing the impact of Entry Level Stewardship on lowland farmland birds in England

Journal Articles & Books
Diciembre, 2010
Europa

Agri-environment schemes (AES) are central to the conservation of Europe's farmland biodiversity. The UK Government's Public Service Agreement target seeks to reverse the decline of farmland birds in England by 2020 through the use of AES. The Entry Level Stewardship (ELS) scheme, introduced in 2005, is the first non-competitive, broad-uptake stewardship scheme designed to deliver simple but effective environmental management on farms throughout England.

Land preservation in British Columbia: An empirical analysis of the factors underlying public support and willingness to pay

Journal Articles & Books
Diciembre, 2008
Canadá

This study extends previous empirical research on land preservation by considering an actual land preservation scheme, the agricultural land reserve in British Columbia, Canada. The reserve was established in 1973 to ensure that development did not occur on the province's most productive agricultural land. 'To ensure that local food production is maintained,' 'the economic importance of British Columbia's agricultural sector,' and 'to protect the environment' are the most important factors that underlie support for the reserve.

Land cover changes in an abandoned agricultural land in the Northern Apennine (Italy) between 1954 and 2008: Spatio-temporal dynamics

Journal Articles & Books
Diciembre, 2015
Italia

We report the spatio-temporal dynamics of land cover changes from 1954 to 2008 in a hilly mountainous area in the Italian northern Apennine, and ecological factors and processes associated with these dynamics. Land cover patches were mapped and analysed at three time periods (1954, 1980 and 2008). Changes over time were detected by analysing a combination of multitemporal source data from airborne images and from field surveys. Relationships between cover classes and environmental variables were analysed for the year 2008.

Applying ecologically based invasive-plant management

Journal Articles & Books
Diciembre, 2010

The need for a unified mechanistic ecological framework that improves our ability to make decisions, predicts vegetation change, guides the implementation of restoration, and fosters learning is substantial and unmet. It is becoming increasingly clear that integrating various types of ecological models into an overall framework has great promise for assisting decision making in invasive-plant management and restoration.

Molecular and functional responses of soil microbial communities under grassland restoration

Journal Articles & Books
Diciembre, 2008
Francia

The influence of ageing grassland on microbial community structure in different long-term grassland regimes compared to tillage in neighbouring fields was investigated to evaluate whether grassland restoration can be considered as a specific type of management for soil conservation in northern France. Microbial community structure was examined by analyzing the distribution of total and labile organic matter, the size of bacterial and fungal populations, and bacterial metabolic fingerprints and fungal genetic fingerprints.
