Monitoring the status of forests and rangelands in the Western United States using ecosystem performance anomalies

Journal Articles & Books
Dezembro, 2013
Estados Unidos

The effects of land management and disturbance on ecosystem performance (i.e. biomass production) are often confounded by those of weather and site potential. The current study overcomes this issue by calculating the difference between actual and expected ecosystem performance (EEP) to generate ecosystem performance anomalies (EPA). This study aims to delineate and quantify average EPA from 2000–2009 within the Greater Platte and Upper Colorado River Basins, USA.

Formation of the brand of territory as an image resource of rural area development

Policy Papers & Briefs
Dezembro, 2012
Bielorrússia

In the conditions of the Republic of Belarus there was shown the necessity of detection and recording of socially-significant sights and brand objects in the process of managing land resources. There was examined the classification of land plots and objects of real estate, which appear to be territory brands. There were determined the main approaches to the formation of the system of such objects on the basic level of state management.

Simulated dynamics of carbon stocks driven by changes in land use, management and climate in a tropical moist ecosystem of Ghana

Sub-Saharan Africa is large and diverse with regions of food insecurity and high vulnerability to climate change. This project quantifies carbon stocks and fluxes in the humid forest zone of Ghana, as a part of an assessment in West Africa. The General Ensemble biogeochemical Modeling System (GEMS) was used to simulate the responses of natural and managed systems to projected scenarios of changes in climate, land use and cover, and nitrogen fertilization in the Assin district of Ghana.

Management effects on European cropland respiration

Journal Articles & Books
Dezembro, 2010

Increases in respiration rates following management activities in croplands are considered a relevant anthropogenic source of CO₂. In this paper, we quantify the impact of management events on cropland respiration fluxes of CO₂ as they occur under current climate and management conditions. Our findings are based on all available CarboEurope IP eddy covariance flux measurements during a 4-year period (2004-2007). Detailed management information was available for 15 out of the 22 sites that contributed flux data, from which we compiled 30 types of management for European-scale comparison.

accidental outcome: Social capital and its implications for Landcare and the “status quo”

Journal Articles & Books
Dezembro, 2012
Austrália

For 25 years the Australian Landcare program has encouraged rural land managers to work cooperatively to resolve natural resource management issues across the nation. Landcare has spread and the model is used internationally. Despite its successes, Landcare has come under criticism for not sufficiently directing land management practices towards environmental sustainability. This criticism sees it as having maintained the “status quo”.

Working Knowledge: characterising collective indigenous, scientific, and local knowledge about the ecology, hydrology and geomorphology of Oriners Station, Cape York Peninsula, Australia

Journal Articles & Books

Austrália

The term, Working Knowledge, is introduced to describe the content of a local cross-cultural knowledge recovery and integration project focussed on the indigenous-owned Oriners pastoral lease near Kowanyama on the Cape York Peninsula, Queensland. Social and biophysical scientific researchers collaborated with indigenous people, non-indigenous pastoralists, and an indigenous natural resource management (NRM) agency to record key ecological, hydrological and geomorphological features of this intermittently occupied and environmentally valuable ‘flooded forest’ country.

Changes over three decades in the floristic composition of fertile permanent grasslands in the Swiss Alps

Journal Articles & Books
Dezembro, 2008

This study investigates how the floristic composition and species richness of fertile grasslands in the Swiss Alps has changed over the last three decades. A total of 259 phytosociological relevés in four regions were resurveyed after periods of between 17 and 29 years. Analysis of the data revealed that floristic composition of the grasslands changed significantly during the study period, although the factor 'time' explained only a small proportion of the total variation (2.0-4.1%).

Clearing of invasive alien plants under different budget scenarios: using a simulation model to test efficiency

Journal Articles & Books
Dezembro, 2010

Clearing of invasive alien plants (IAPs) is a necessary but expensive exercise. Typically, insufficient resources are available to clear all areas simultaneously. Consequently areas need to be prioritized for clearing. The financial resources available determine the extent of the area which can be cleared, while the prioritization identifies the location of the areas to be cleared. We investigate the following questions: (1) How does a change in the budget impact on the efficiency of the clearing operations over time? (2) How does this differ for different sites?

Countryside elements and the conservation of birds in agricultural environments

Throughout the world, many native species inhabit agricultural landscapes. While natural habitats will form the cornerstone of conservation efforts in production-oriented environments, the success of these efforts will be enhanced by a greater understanding of the potential contribution of the increasingly modified countryside ('matrix') elements in these landscapes. Here, we investigate the relative occurrence of birds in some landscape elements (i.e. land-uses, vegetation types) common to agricultural environments around the world.

Initiating dialogue between scientists and managers of biological invasions

We describe an initiative to improve the flow of information between researchers and managers as part of two international scientific symposia on biological invasions held in South Africa in 2008 and 2009. Formal workshops and information sessions for land managers were run during the symposia. At the end of each symposium, the managers ran dedicated question-and-answer sessions on the research they felt was needed to improve their work. We discuss the potential of such interventions to increase interaction and awareness between researchers and managers of biological invasions.

Improving irrigation water operation in the lower reaches of the Amu Darya River – current status and suggestions

Irrigated agriculture is widespread in the Central Asian drylands and important for food security of the region. However irrigation practices based on rules made for cotton production on large units do not provide adequate guidance for the now widespread small farms that produce cotton wheat and rice. Excessive unsustainable water use is the consequence. Land and water resource management practices were analysed in 2006 for the irrigated area (approx. 1885 ha) of a water users' association (WUA) as a case study.
