David Buckland,Founder, Cape Farewell,with Renée Lertzman

Cape Farewell is the brainchild of London-based artist David Buckland. The project is centered round a series of sailing voyages into the Arctic, through routes that were previously icebound but are now passable. The expeditions take teams of world-renowned artists, educators, writers, musicians and thinkers into the Arctic, onboard a hundred-year old schooner, with the invitation to engage with scientists (from the National Oceanography Centre, as well as Southampton), to make art, and to draw people's attention to the effects of ocean currents on us and our climate. Since its first expedition in 2003, the project has grown to include educational programs, an award-winning website, a BBC documentary, and an exhibit, “The Ship, The Art of Climate Change,” developed with the Natural History Museum and which has embarked on a worldwide tour. In August 2007, Cape Farewell began a three-year residency at Southbank Centre, operating as a cultural eco-hub for the Centre's creative climate change initiatives, and has started a collaboration with the Eden Project in Cornwall, UK.

This interview was conducted in the Cape Farewell offices, which are in David Buckland's studio atop his family home in Camden, London. Currently, Renée Lertzman is conducting a PhD in critical psychology studies at Cardiff University in Wales, UK. Her interviews and writings relating to environmental communication have appeared in The Sun Magazine, Orion, Land and People (Trust for Public Land), Speak Magazine, Terra Nova, and Organization & Environment.

Wind farm and fauna interaction: detecting bird and bat wing beats through cyclic motion analysis

Recent Government announcements have implied that wind power will play a major part in providing energy for the UK (BBC 2007 BBC. 2007. Wind ‘could power all UK homes’ [online], British Broadcasting Corporation. Available from: http://news.bbc.co.uk/1/hi/uk_politics/7135930.stm [Accessed 20 January 2008] [Google Scholar]). However, there is much concern that wind farms can have a significant impact on flying fauna (bats and birds) using the area, particularly at night. As part of an Environmental Impact Assessment, thorough appropriate surveys are necessary for quantifying and minimising any risk wind farms may cause flying fauna. Manual surveys that are commonly used are not always cost‐effective, efficient or practical. Remote systems based on motion detection are increasingly being used to monitor wildlife.

Fast‐moving airborne targets such as aeroplanes can falsely trigger motion‐detection based remote systems. As birds and bats repetitively flap their wings, this oscillating motion can be used to distinguish them from other airborne targets. Time periods between wing oscillations are not always constant, and hence the motion is not periodic. A method to detect cyclic motion based on similarity matrices is proposed, and synthetic and real data are used.     

Analysis of the Energy Embodied in Foreign Goods Trade of China

In recent years, scientists have been increasingly interested in the energy embodied in traded goods among countries. In this article, the direct energy intensities in various economic sectors of China were calculated with the data of energy consumption and output value of each sector, and the input-output table was used to estimate the external energy consumption. The total energy intensity of all sectors was then obtained. From the data of international trade, the energy embodied in goods trade of China was estimated for the period of 1994-2001. During this period, the average energy intensity of imported goods was always higher than that of exported ones. As a country with a surplus in international goods trade, China actually imported net embodied energy in the past few years. The net embodied energy imported was at the same magnitude of the imported energy in the form of fossil fuels.     

Atmospheric Mercury Pollution in Beijing

The atmospheric mercury pollution in Beijing is a serious problem. Atmospheric mercury has three sources： natural emission, anthropogenic emission and previously deposited mercury reemission or recycling, composing elemental mercury, divalent mercury and particulate-phase mercury. Many studies showed that mercury in Beijing＇s air was higher than the general level of mercury concentration in the atmosphere. Mercury emission sources were discussed. Industrial emissions, coal burning, vehicle exhaust emissions and waste incineration were thought to be the main sources of atmospheric mercury pollution in Beijing. And also meteorology has an effect on atmospheric mercury concentration in Beijing. Measures have been taken to control the emission of mercury into the air in recent years.     

CO_2 Emissions Embodied in China-U.S.Trade

After the Kyoto Protocol was implemented, carbon leakage exerts great influences on international trade and economy. Trade creates a mechanism for consumers to shift environmental pollution associated with their consumption to other countries. China has overtaken the U.S. as the world＇s biggest CO2 emitter since 2006. As China＇s second largest trade partner, the U.S. has the biggest trade deficit with China which has aroused a lot of disputes between the two parties. But so far the assessments of the trade imbalance of China-U.S. have paid little attention to environmental impacts associated with the trade imbalance. Applied an input-output approach, the article estimates the amount of CO2 embodied in China-U.S. trade during 1997-2007. It was found that through trade with China, the U.S. reduced its CO2 emissions compared with a non-trade scenario. Due to the greater carbon-intensity and relatively less efficient production processes of Chinese industry, China-U.S. trade resulted in more CO2 emissions in China and the world. In the end, the article gives some suggestions： it is equal and sustainable that the international accounting methodologies should be improved, for CO2 emissions responsibility must be designed to account for the dynamic nature of international trade.     

Study on the Circular Agriculture Development in Beijing＇s Mountain Areas

Circular agriculture is an essential way to realize the positive recycling of ecology and harmonious development of the country construction. The sustainable development of Beijing＇s mountain areas depends on the background and orientation of ecological economy. Beijing＇s mountain areas bear the responsibility of protecting the ecological safety of the whole Beijing district and also the exploration of circular agriculture in mountain areas is very important to promote the sustainable use of agriculture resources. Beijing＇s mountain areas have possessed some practical experience in recycling agriculture development. Through summarizing the development mode and analyzing the development practice, the article puts forward three key segments of promoting Beijing circular agriculture development： strengthen propagate, develop superiority and built management mechanism.     

Physical Land Suitability Assessment for the Large Cardamom Amomum subulatum Roxb. Cultivation in Hills of Kathmandu Valley

Nepal is one of the top three exporters of larger cardamom （Amomum subulatum Roxb.） in the world market contributing largely to the Nepalese economy. Sub-Himalayan range of hilly area of eastern Nepal is popular for large cardamom cultivation. Being similar phytogeographical and ecological setting, cultivation has begun in hills of Kathmandu Valley however land suitability needs to be evaluated with reference to specific need of the crop. Kathmandu is a valley with alluvial bottom and altitudinal range between 1200 and 2730m above sea level having cool to warm temperate climatic range. Varieties of aspects and slope gradient have potentiality for the large cardamom cultivation. Aim of the study was set to categorize available land area in the range of suitability for large cardamon cultivation on the basis of physical characteristics of the land and ecological need of crop. Land evaluation methodology has been designed along with site specific amendment in FAO framework （1976）. Land use map in scale of 1：25 000 was used in geographic information system environment. Suitability was done through map overlaying methods. Aim of the study was set to categorize available land area in the range of suitability categories for large cardamom cultivation based on physical characteristics of the land matching with ecological need of crop. Analysis of data shows that altitudinal range at uplands of Kathmandu Valley and annual average rainfall and temperature are found to be within suitability range for Amomum subulaturn cultivation. Sandy loam soil, slightly acidic in nature with gentle sloping land of about 5-8° provides highly suitable condition. Result showed that more than one-third of total land area above 1800 m of altitude is suitable. Selectively, of the total area, 5% are north facing slope, 13% gentle slopes are highly suitable. 16% lands with north east orientation are moderately suitable. Most of the land areas which are marginaly suitabile for vegetable and cereal crops are highly suitable for large cardamom. Hills of northern boundary hills found to be suitable due to more rainfall distribution pattern compared to southern boundary hills. Therefore, land evaluation also identifies limitations and input requirements for sustainable production.     

Analyzing and Pondering on the Regulation of Urban Construction Land Expansion

Along with the economic development and the acceleration of urbanization, urban construction land expands rapidly in China, and has resulted in a series of socio-economic problems. This article summarized the major points of controlling the unchecked and rash expansion of construction land in the academic circle, and analyzed the problems of regulating the expansion of construction land from three aspects. First, this article analyzed the relationships between socio-economic development and urbaniza- tion from the historical viewpoints, and pointed out that the expan- sion of construction land is a historical phenomenon which will be surely appeared in the development of human race. Second, the authors utilized two-sector model to analyze the importance of urbanization in the socio-economic development from the academic angles. At last, the authors utilize four-quadrant model and bidrent curve model to analyze the influence that brought by the strict control of construction land expansion. Through analysis, this article drew some conclusions. First, the expansion of construction land is a phenomenon which will surely appear in the social development. It is impossible to accomplish the national modernization on the basis of dualistic structure between urban and rural areas. Second, under the function of rent gradient gap, strict control of construction land expansion will not only obtain the anticipated effects, but also cause a series of socio-economic problems, such as land-levying contradiction, the appearance of limited property right house, and being dependant on lease instead of expropriation. Third, unreasonable policies and governmental behaviors are the roots of the unchecked and rash expansion of urban construction land. Based on these conclusions, this article proposed that three transformations should be realized to regulate the unchecked and rash expansion of construction land： transfers from quantity regulation to quality regulation, from direct regulation to indirect regulation, and from single-measure regulation to multi-measures regulation.     

China＇s Total Emission Control Policy： a Critical Review

As part of a comprehensive environmental management system, many countries establish emission control targets for mass emissions of a pollutant. Such targets are often the key objective of an environmental policy, such as an emission trading program. In China, however, it is more than just an objective of one particular policy; it has become a concept that has influenced many national environmental policies and activities. The objective of this article is to review the implementation of the total emission control policy in the past 10 years and explore emerging issues in its implementation. The article has three sections： a summary of the implementation experience, issues with the design and implementation of the policy, and policy recommendations.     

Adaptive mechanisms of nonspecific resistance to heavy metal ions in alkanotrophic actinobacteria

Sensitivity to heavy metal (HM) exposure has been studied in actinobacterial cultures maintained at the Regional Specialized Collection of Alkanotrophic Microorganisms (acronym IEGM; http://www.iegm.ru/iegmcol). Possible mechanisms of nonspecific resistance of actinobacteria to HMs are discussed, which may be due to their ecological preferences, alkanotrophy, and ability to synthesize biosurfactants. Hydrocarbon-oxidizing strains have been selected that are characterized by high emulsifying activity and resistance to increased (>250 mM) HM concentrations.     

Integrating disaster risk reduction and climate change adaptation: key challenges—scales, knowledge, and norms

Statistical data shows that the increase in disasters due to natural hazards over the past 20 years has, for the most part, been caused by meteorological and hydrological events. This increase has been largely assigned to climate change [Centre for Research on the Epidemiology of Disasters (CRED), 2010, http://www.emdat.be/Database/Trends/trends.html], that is, with climate-related hazards being major triggers for the majority of disasters. Consequently, there is obvious concern about how a changing climate will exacerbate the situation in the future (McBean and Ajibade in Curr Opin Environ Sustain 1:179–186, 2009). However, the attribution of a single hazard event or specific losses to climate change is still difficult, if not impossible, due to the complexity of factors that generate disaster losses. Disaster risk is a product of the interaction of the hazard (event) and the vulnerability conditions of the society or elements exposed. As a result, the need for a systematic linkage between disaster risk reduction (DRR) and climate change adaptation (CCA) to advance sustainable development, and finally human security is being discussed within the ongoing climate change negotiations as well as within the disaster risk community, for example, in the framework of the Intergovernmental Panel on Climate Change special report on ‘Managing the risks of extreme events and disasters to advance climate change adaptation’. However, crucial differences between DRR and CCA exist that have widely limited or hampered their integration in practice. A review of existing literature on the topic and current national and local adaptation strategies, as well as 38 expert interviews conducted between April and May 2009, have led the authors to hypothesise that most of these differences and challenges can be categorised with respect to different spatial and temporal scales, the knowledge base, and norm systems. This paper examines the reasons for the practical barriers when linking CCA and DRR according to these three aspects. Finally, we outline recommendations and measures that need to be adopted in order to overcome existing barriers. In addition, quality criteria are formulated that should be applied in order to constantly monitor and evaluate adaptation strategies designed to simultaneously meet DRR requirements and vice versa.     

A Review of Environmental Sociology and the Sociology of Natural Resources： Insights for the Development of Environmental Sociology in China

Environmental sociology and the sociology of natural resources are two key subdisciplines of the sociological study on the interactions between nature and human society. Previous discussion on the relationships of these two fields has largely focused on their distinctions and synthesis in western （particularly American） academia. Environmental sociology emerged as an important sociological subdiscipline in China in the early 1990s and is under vigorous disciplinary construction at present. By contrast, the sociology of natural resources is still a novel term for most Chinese researchers. This article provides a systematic review of recent literature on the relationships between environmental and natural resource sociologies, which should provide important implications for the further development of environmental sociology in China.     

Population and Environment： Necessary Transition Initiatives for Developing Countries

Now environment is an important topic in academic field. Many researches focus on the negative outcomes of nature which are being continually created by human and much attention has been paid to how the environment is protected through integrated research, movement and policy. But few studies are concentrated on population and environment and are to find out the interconnectivity and underlying mechanism that have an effect on people＇s preferring additional children and perception to environment. Many researchers claim that population growth is a great problem for environment but they do not provide the indepth integrated knowledge and mechanism that influence fertility trend and environmental problems. It is very crucial to develop practical and concrete initiatives to confirm a transition to reduce population growth and redirect the perception on population and environment.     

Evolution Rules of Urban-rural Development and Inspiration for China＇s Agriculture

Based on urban-rural contrast coefficient, this article designs the agriculture relative development index （ARDI） as indicators measuring the intensity of urban rural dual structure which is comparable among the countries of the world. This article calculates ARDI of 40 countries from 1980 to 2004. The result shows that ARDI in the developed countries and most of the middle-income countries are rising and yet there are declines in most of the low-income countries. The result also showed that most countries＇ ARDI will see a decline at the earlier stage of industrialization, so their dual economic structure will also aggravate and urban-rural gap will widen. With the economic development, the tendency will change and ARDI presents a U-shape change overall. The turning point is when a country becomes a middle-income one.     

Study on Development of the West of Shandong Province Based on Overall Regional Development Planning Pattern

The overall regional development planning pattern has been considered to be a new and effective pattern as for development of provincial economy. The article analyzed the current conditions of the west of Shandong Province and tried to find the generation mechanisms of current non-balanced economic devel- opment of Shandong Province. And then approaches to regional development were put forward according to the theory of regional development pattern as a whole.     

Technological Progress, Structural Change and China＇s Energy Efficiency

China has witnessed rapid economic development since 1978, and during the time, energy production and consumption developed at a tremendous speed as well. Energy efficiency which can be measured by energy consumption per unit of GDP, however, experienced continuous decrease. Theoretically, the change of energy efficiency can be attributed to industry structural change and technological change. In order to explain the transformation of Chinese energy efficiency, we adopt logarithmic mean Divisia index techniques to decompose changes in energy intensity in the period of 1994-2005. We find that technological change is the dominant contributor in the decline of energy intensity, but the contribution has declined since 2001. The change in industry structure has decreased the energy intensity before 1998, but raised the intensity after 1998. Decomposed technological effects for all sectors indicate that technological progresses in high energy consuming industries such as raw chemical materials and chemical products, smelting and pressing of ferrous metals, manufacture of non-metallic mineral products and household contribute are the principal drivers of China＇s declining energy intensity.     

Promoting Sustainability with Ecological, Economic and Social Dimensions in Developing Countries

Sustainable development is one of the most important ideas, and goals of our time. It is defined as ＂development which meets the needs and aspirations of the current generation and develops safe and sound society for future generation＂. Achieving sustainable development thus involves a vigorous and urgent debate on different dimensions. The different dimensions of sustainability as a framework involve all issues such as science, technology, economic growth and development, health, education, finance investment and trade, politics, natural disasters, population growth and terrorism, etc. No single dimension is responsible to develop sustainable society. This article mainly described the integrated relationship among the three dimensions ofsustainability.     

Climate-induced Changes in Spring Maize Water Requirement in Xiliaohe River Watershed

Xiliaohe River watershed plays an important role in regional and national grain security. With the development of society and economy, water consumption that increased dramatically causes water shortages. Crop water requirement can provide quantitative basis for making regional irrigation scheme. In this study, spring maize water requirement is calculated by using PenmanMonteith formula and spring maize coefficient from May to September at 10 meteorological stations in Xiliaohe River watershed from 1951 to 2005. The variation trend of the spring maize water requirement during the whole growing stage, water requirement in every month, and meteorological influencing factors are obtained by using Mann-Kendall method, and the degree of grey incidence between the water requirement and meteorological influencing factors are shown. The results are the spring maize water requirement during the whole growing stages increases at half of the stations in Xiliaohe River watershed, and are remarkably affected by the water requirement in May. The monthly mean, maximum and minimum air temperature form May to September show an increasing trend in Xiliaohe River watershed in recent 55 years. The monthly mean and minimum air temperature increases notably. The relative humidity, precipitation, wind speed and sunshine show a decreasing trend with variety for different months. The monthly maximum air temperature, wind speed, sunshine and monthly mean air temperature have the highest correlation degree with spring maize water requirement from May to September.
