Risk, rescue and emergency services: The changing spatialities of Mountain Rescue Teams in England and Wales

This paper considers the role of the emergency services in society and, in particular, their role in controlling, mitigating and resolving risk. Using a network approach, Mountain Rescue Teams are studied in order to examine how people, agencies, animals, technology and knowledge are deployed to resolve emergencies. The paper traces the changing nature of risk in rural places and the impact of state regulation on the deployment, spatialities and practices of the emergency services. In doing so, it argues that greater attention should be paid to the emergency services by geographers.

Research on Ecosystem Service Consumption in Guilin City

Research on ecosystem service consumption not only helps to reveal the utilization intensity and management level of the ecosystem in Guilin, but it also provides a scientific basis for ecosystem investment, trade, subsidies and taxation by the Guilin government departments. Based on household survey data of urban and rural ecological consumption, the physical quantity accounting method is adopted for multivariate statistical analyses, such as analysis of variance and multiple comparison. This analysis reveals the differences and changes in the consumption level, consumption structure and consumption pattern of the main ecological products in Guilin among the various counties. The results fit into four main themes. (1) The annual per capita consumption of the main ecological products in Guilin varies either extremely significantly or significantly among the counties, but the consumption level of ecological products varies according to the type of products. There are significant or extremely significant differences in the annual per capita consumption of cereals, melons and fruits, pork, poultry, beef and mutton, fresh eggs and milk between urban and rural residents. (2) There are extremely significant differences in the annual per capita consumption of fruits, pork, poultry, beef and mutton, fish, fresh milk and vegetable oil among urban residents in different counties. There are also extremely significant differences in the annual per capita consumption of cereals, pork, poultry and alcohol among rural residents in different counties, and significant differences in the annual per capita consumption of fresh eggs and milk. The consumption level of ecological products by urban and rural resident varies with the type of products. (3) The ecological consumption patterns of all counties in Guilin mainly follow the “cereal + vegetable + fruit + meat” pattern for urban residents and the “cereal + vegetable + meat” pattern for rural residents (except for the rural residents in Pingle, which show the “cereal + vegetable” pattern). The consumption structure of urban residents is better than that of rural residents. (4) There is a large gap between the ecological consumption of urban and rural residents in Guilin and China's recommended standards, except for cereals and meat. The main problems are excessive meat intake, and insufficient intake of dark vegetables, fruits, eggs, milk and fish. Therefore, we should make full use of forestland, grassland, water and other resources in the area, and vigorously develop fishery, fruit and vegetable production and herbivorous animal husbandry to meet people's ecological needs for dark fruits and vegetables, eggs, milk and fish in Guilin City.     

Valuation of lake and marsh wetlands ecosystem services in China

Wetlands are highly productive natural ecosystems, providing valuable goods and services. There is growing interest in transferring ecosystem service value from the existing wetlands studied to other wetlands ecosystems at a large geographic scale. The benefit transfer method uses the known values from wetlands to predict the value of other wetland sites. This methodology requires only limited time and resources. The present study calculated the value of the ecological services provided by lake and marsh wetlands in China in terms of biodiversity indices, water quality indices and economic indices. Basic data on wetlands were obtained through remote sensing images. The results show that: 1) The total ecosystem service value of the lake and marsh wetlands in 2008 was calculated to be 8.1841 × 1010 United States Dollars(USD), with the marsh and lake wetlands contributing 5.6329 × 1010 and 2.5512 × 1010 USD, respectively. Values of marsh ecosystem service were concentrated in Heilongjiang Province(2.5516 × 1010 USD), Qinghai Province(1.2014 × 1010 USD), and Inner Mongolia Autonomous Region(1.1884 × 1010 USD). The value of the lakes were concentrated in Tibet Autonomous Region(6.223 × 109 USD), Heilongjiang(5.810 × 109 USD), and Qinghai(5.500 × 109 USD). 2) Waste treatment and climate regulation services contributed to 26.29% and 24.74% respectively, of the total ecosystem service value of the marsh wetlands. Hydrological regulation and waste treatment contributed to 41.39% and 32.75%, respectively, of the total ecosystem service value of the lake wetlands. 3) The total ecological service value of the lake and marsh wetlands was 54.64% of the total service value of natural grassland ecosystems and 30.34% of the total service value of forests ecosystems in China.

Performance of a northwestern Mediterranean bottom trawl fleet: How the integration of landings and VMS data can contribute to the implementation of ecosystem-based fisheries management

The European Union has established a framework to achieve or maintain good environmental status in the marine environment by 2020. The Marine Strategy Framework Directive requires the application of the ecosystem approach to the management of human activities, covering all sectors having an impact on the marine environment. However, fisheries in the Mediterranean are far from a systematic implementation of an ecosystem-based fisheries management (EBFM). Aiming to address this issue, this study explores the potential of the relationship between daily yield by vessel (landings and income by species) and vessel position (known via vessel monitoring system) as a tool for fleet management. This approach is possible due to the current dynamics of Mediterranean fleets, with vessels returning daily to the harbour where landings are registered as weight and income by vessel. Moreover, vessels of >15 m total length have been compulsory monitored by VMS since 2005. A bottom trawl fleet that operates in the northwestern Mediterranean was chosen to develop this approach. Different groups of trawlers were identified, which could be linked to the strategies displayed by the fishermen that were mainly driven by the target species dynamics. Accurate knowledge of the fishing targets driving the fleet dynamics and of the fishing strategies at the vessel level (i.e. fishing ground habitat where the fishing pressure is exerted and corresponding landings) are shown to be a feasible tool for fleet management.     

Outstanding challenges for urban conservation research and action

Researchers, advocates and policymakers have proposed urban conservation as an emerging, integrative discipline that can contribute to sustainable cities by delivering co-benefits to human and non-human components of biodiversity. Given the recent growth in biodiversity-friendly designs and management schemes, there is an urgent need for a synthesis of this fragmented research base to inform planners and decision-makers. We conducted a systematic multidisciplinary literature review (787 papers) and found that the importance of urban areas for general conservation is not convincingly supported by empirical research. Only few studies demonstrated that cities can directly contribute to conservation efforts, by hosting viable populations of rare or endangered species, or by providing green corridors for the passage of natural populations. From a social perspective, while several studies demonstrated that green infrastructure could provide services for people (notably cultural services), only few studies explored the role of species diversity per se. Our review also shows strong geographical, location and taxonomic biases in urban biodiversity conservation research that make generalisations difficult. It is a disturbing paradox that while research in urban biodiversity conservation is rising exponentially, the main motivations for conserving urban biodiversity remain largely untested and unproven. We thus propose a framework for promoting integrative urban conservation research to bridge those gaps. Together, these findings warn against expanding cities under green planning and call for enhancing biodiversity experience by improving the quality of existing green spaces throughout the entire urban matrix. We provide a set of recommendations for practitioners and decision-makers to continue action.
