Displaying 441 - 445 of 1605integrated representation of the services provided by global water resources
Water is essential not only to maintain the livelihoods of human beings but also to sustain ecosystems. Over the last few decades several global assessments have reviewed current and future uses of water, and have offered potential solutions to a possible water crisis. However, these have tended to focus on water supply rather than on the range of demands for all water services (including those of ecosystems). In this paper, a holistic global view of water resources and the services they provide is presented, using Sankey diagrams as a visualisation tool.
Factors determining use of biological disease control measures by the avocado industry in South Africa
Farmers in the northern avocado cultivation areas of South Africa were interviewed concerning their experience and perceptions of biological control. Factors affecting their decision to use biological control programmes as a disease control strategy, were also investigated. Results indicate that educational level, age and land owner status reflect the farmer's decision making ability and the level of commitment to adopt the new technology.
Influence of territorial variables on the performance of wildfire detection systems in the Iberian Peninsula
Wildfire detection systems planning is an essential component of national and regional wildfire management policies. The common resources usually used in wildfire detection are lookout towers, terrestrial mobile brigades, aerial reconnaissance and the general public.
Interactions between ecological and social drivers in determining and managing biodiversity impacts of deer
The management of wildlife and its impacts on biodiversity is likely to be most successful where ecological understanding is integrated with the economic and social drivers for management, and where the attitudes and behaviour of stakeholders are fully understood. Collaboration between stakeholders at the landscape level is suggested as the most efficient ‘model’ for the management of many wildlife species such as deer. However, there has been limited research to evaluate the effectiveness of collaborative management for deer or how it is perceived by individual landowners.
Macroinvertebrate assemblages of peatland lakes: Assessment of conservation value with respect to anthropogenic land-cover change
Small blanket bog lakes can contain many rare and threatened aquatic invertebrate species. Their conservation value, however, is threatened throughout Europe by peat extraction and particularly conifer afforestation, which can compromise the physico-chemical habitat quality of peatland lakes through excessive inputs of forestry-derived dissolved and particulate substances.
