Achievements, difficulties and future challenges for the FARMING network

The EC FARMING network (Food and Agriculture Restoration Management Involving Networked Groups) was set up to bring together the many and diverse stakeholders who would be involved in intervention following wide scale radioactive contamination of the food chain, so that acceptable strategies can be developed for maintaining agricultural production and safe food supply. The network comprises stakeholder panels in the UK, Finland, Belgium, France and Greece that have met regularly since 2001 to debate, discuss and exchange opinion on the acceptability, constraints and impact of various countermeasure options and strategies. The objectives of this paper are to consolidate the main achievements of the FARMING project over the period 2000-2004, to highlight the various difficulties that were encountered and to discuss the challenges for engaging stakeholders in off-site emergency management and long-term rehabilitation in the future.     

Nutrient export by rivers to the coastal waters of China: management strategies and future trends

We analyzed past and future trends in river export of dissolved nitrogen (N) and phosphorus (P) to the coastal waters of China, for a selection of rivers, as calculated by the Global NEWS models (Nutrient Export from WaterSheds). Over the period 1970–2000, river export of dissolved nutrients increased considerably, especially of dissolved inorganic N and P. Anthropogenic sources of N and P in rivers have become increasingly important, in particular N and P losses from agriculture. We tested the sensitivity of calculated nutrient export by rivers to changes in selected controlling factors. The calculated export of dissolved N and P is sensitive to changes in hydrology, synthetic fertilizer use and manure excretion in river basins. Changes in sewage inputs have large effects on dissolved inorganic P export. We analyzed future trends up to 2050 for several scenarios to illustrate the combined effects of selected management options. In the Base Scenario, the N and P export by the selected rivers increases considerably between 2000 and 2030. The increase continues from 2030 to 2050 except for DIP. Strategies to reduce N and P export by rivers include changes in agriculture, sewage and energy use. Changes in agriculture have the largest impact on future dissolved N and P river export to the coastal waters of China. The effectiveness of reduction strategies differs between nutrient forms and basins.     

自愿型环境规制:研究进展及未来展望

环境规制工具的选择决定了生态环境保护的成效,环境规制研究也是当前资源环境领域的研究热点之一。根据政府赋予被规制对象自由裁量权空间从小到大,可以将规制工具分为纯粹政府规制、元规制、自我规制、无约束的自由四种类型。既有研究对传统的纯粹政府规制工具给予了大量的关注,相比而言,对元规制和自我规制等自愿型环境规制工具的关注相对较少。已有的自愿型环境规制的研究主要从俱乐部物品理论、制度主义理论、利益相关者理论等视角出发,探讨自愿型环境规制的供给和需求问题。自愿型环境规制工具作为一种俱乐部物品,实践中面临的最大挑战在于如何克服企业的“搭便车”行为。现有的实证研究分别将自愿型环境规制作为自变量和因变量,分别探究①自愿型环境规制对企业环境绩效和经济创新绩效的影响,以及②企业参与自愿型环境规制的内外部动因。对比国内外文献我们发现,目前基于中国的社会经济背景下的自愿型环境规制的研究非常欠缺,这主要是因为中国在环境规制领域具有长期使用纯粹政府规制工具的传统,自愿型环境规制的实践较为欠缺,目前在中国实践较为广泛的自愿型环境规制工具仅有ISO14001环境管理体系以及化工行业的“责任关怀”体系。最后,本文基于现有对于中国自愿型环境规制研究的不足,展望了未来研究可能的方向。我们认为既有对于自愿型环境规制的研究更多关注对企业绩效的因果效应,而对其如何影响企业绩效的因果机制识别不足;此外,现有文献很少将中国特色的政治、经济、社会因素纳入自愿型环境规制的研究领域,未来的研究应当多从这两个方面着手深入。     

Promoting e-mobility in India: challenges,framework, and future roadmap

The purpose of the research is to identify the critical challenges that are impeding the adoption of e-mobility in India. It also aims to give a roadmap how to address these challenges while taking into considerations concerns of all the relevant stakeholders. Based on an in-depth literature review, an exploratory research design is employed to delve deep into various aspects of e-mobility. This is followed by a three-phase Delphi technique to identify and rate the e-mobility challenges in the Indian context. The study successfully identifies four different categories of challenges and proposes integrative framework for e-mobility. Further, the research goes on to lay out the future roadmap for mass adoption of electric vehicles (EVs) in India. The research is novel in terms of presenting a holistic viewpoint on e-mobility in India. Its originality lies in identifying the major inhibitors obstructing EVs adoption in India and then suggesting the roadmap how to overcome these impediments for mass adoption of e-mobility.

Shifting drivers and static baselines in environmental governance: challenges for improving and proving water quality outcomes

Understanding the conditions that enable or constrain success in environmental governance is crucial for developing effective interventions and adapting approaches. Efforts to achieve and assess success in environmental quality improvement are often impeded by changes in conditions that drive outcomes but lie outside the scope of intervention and monitoring. We document how long-term changes in land use, agriculture, and climate act as non-stationary, shifting drivers of change that combine to render water quality management interventions less effective and increasingly difficult to assess. Focusing on the Yahara River watershed of south-central Wisconsin, USA, we ask how baselines influence program modeling, monitoring, and evaluation, as well as adaptation in governance approach. Through historical trend, GIS, and policy and qualitative data analyses, we find that changes in long-term land use and precipitation pattern dynamics exert tremendous pressure on water quality outcomes but are not captured in snapshot baseline assessments used in management planning or evaluation. Specifically, agricultural sector change related to the intensification of milk and manure production is increasingly challenging to address through best management practices, and flashier precipitation associated with climate change makes it difficult to achieve goals and establish a causal connection between management interventions and outcomes. Analysis of shifting drivers demonstrates challenges facing environmental governance in the context of climatic and social–ecological change. We suggest that goal setting, program design, and evaluation incorporate new modes of analysis that address slowly changing and external determinants of success.     

From economic to environmental sustainability: the forest management debate in 20th century Finland and Sweden

The issues of sustainability, efficiency, and profitability in private forestry dominated debate on Finnish and Swedish forest policy throughout the 20th century. The management and utilization of private forests have been significant for these countries since more than half of productive forest land has been owned by families. Forests have also played an important role in Finland’s and Sweden’s national economies. There was however no consensus among forest owners and forestry experts—forest scientists and forestry authorities—about the methods of achieving forestry sustainability and profitability, particularly in the early 1900s. This article focuses on the types of argument on which perceptions of good forest management were based, and the reasons for their use. The article also explores how disagreements and occasional open conflicts between private forest owners and forest authorities were solved, and what kind of regulative means were developed to avoid such differences. There are three main reasons for making a case study of Finland and Sweden: Firstly, the forest sector has played an important role in their national economies, secondly, the objectives and content of their forestry laws are quite similar, and thirdly, the tradition of family forest ownership has remained strong. The debate on good forest management in this period revolves around the two silvicultural paradigms: even-aged and uneven-aged systems. The former concerns formal, scientific knowledge of forest management, and the latter takes a traditional approach.     

Continuous radioactivity monitoring systems. From the pre-history of radioprotection to the future of radioecology

The first significant quantities of artificial radioactivity appeared in the environment around the end of the 1940s. They were gigantic and their metrology very quickly seemed to be essential for sanitary and military reasons. In the 1950s, the first continuous monitoring systems of "fall out" were created. They were neither automatic nor sensitive and radioprotection of the environment was not a concern only for simple public information. Since then, radioecology, technology and evolution of our mentality have completely modified our way of thinking. Thus, from the 1980s up to the dawn of the new millennium, the gap between the performances of metrology laboratories and certain aspects of direct measurement has almost disappeared. 1986 certainly contributed a lot to the concept of surveillance networks and alarm systems, emphasising that the major advantage of these is the fact that they are operational, the minute before the accident.

A review of regulatory decisions for environmental protection: part I - challenges in the implementation of national soil policies

Since many soil studies have already revealed the possible risks to human health and the environment arising from contaminated soils it is therefore crucial to preserve soil quality under current and future conditions. In the last three decades a number of countries already introduced national policies and practices for the management of contaminated sites, and in 2002, an EU Thematic Strategy for Soil Protection was proposed by the European Commission. In this paper we review and analyse several national contaminated land policy regimes already in place in order to assess common elements and to identify specific needs in the development of national soil policies. We propose a framework that combines the D-P-S-I-R structure of policy evaluation with the Source-Pathway-Receptor approach to health risk assessment to support the development of effective country specific regulatory decisions for managing contaminated land in countries where these are yet to be implemented. The framework proposed allows decision makers to effectively use available information and to identify existing data gaps. As a result it is apparent that while there are technical aspects of site characterisation, risk assessment and remediation processes that could be commonly implemented at an EU level there are certain trans-scientific aspects that require political choices and need to be customized by EU Member States.

From past to future: impact of climate change on range shifts and genetic diversity patterns of circumboreal plants

Climate change is projected to influence the genetic resources of plant species. Recent research has examined genetic diversity patterns under current climate conditions, with little attention to the future genetic consequences for species. In this study, we combined ecological niche modeling and population genetic approaches to project future changes in genetic diversity using plastid and nuclear DNA and reconstructed distribution patterns of three circumboreal plants (Chamaedaphne calyculata, Linnaea borealis ssp. borealis, and Pedicularis sceptrum-carolinum ssp. sceptrum-carolinum) in the last glacial maximum. We found that circumboreal plants could potentially lose their geographic ranges in the future (2070; 35–52% in RCP 4.5 (representative concentration pathways), 37–53% in RCP 6.0, and 56–69% in RCP 8.5), only slightly compensated by a predicted range gain of 18–33% (across the three RCPs). It is expected that future genetic diversity level could remain similar or lower than the present level. On the other hand, the homogeneity of the genetic background—a lack of admixture and domination of one gene pool in most populations of C. calyculata and L. borealis ssp. borealis—was predicted to become more pronounced in the future. Combining the paleoecological niche modeling and genetic data revealed, more precisely, the climate refugia for circumboreal plants in the Alps, central Asia, Beringia, and southern North America and the macrorefugia more restricted to the northern part of Eurasia and North America, reaching the arctic zone.

     

Evolutionary-ecological analysis of trends in phenogenetic variation of homologous morphological structures: From populations to ecological series of species

An evolutionary-ecological analysis of homologous variations in cranial morphological structures (phenes) has been performed at the level of populations and subspecies exposed to technogenic, climatic, and landscape-geographic changes in the environment, as well as with ecological series of 46 species and infraspecific forms differing in ecological specialization within the family Cricetidae. On this basis, consistent manifestations of phenogenetic variation have been revealed. Species with the same ecological specialization show parallel directional changes in the frequencies of homologous phenes and their individual combinations. These changes apparently have adaptive significance and result from rearrangements in the ancestral epigenetic system. It is shown that similar ecological requirements imposed by the environment historically lead to unidirectional transformations of homologous morphological structures in different species, which may account for high incidence of homoplasy as well as for the parallel and, in part, directional evolution of closely related taxa with similar ecological specialization.

Willingness to pay for environmental quality: Evidence from survey data

The environmental movement evidenced a period of extremely rapid growth during the 1960's and early 1970's. Some recent studies have indicated a decline in general public concern with environmental problems. In this paper we attempt to provide some new evidence which might be of assistance in ascertaining the relative status of concern for the economy, concern for the environment, and willingness to pay for environmental quality. The study focuses upon a major city in a large energy producing state with a large ethnic (Mexican-American) minority. Our data indicate that concern for the environment is not a highly salient issue for our respondents. Economic concerns far outweigh enviromental issues. Additionally, willingness to pay for environmental quality is not a unidimensional trait. Perception of who is responsible for pollution rather than perception of a deteriorating environment is a significant indicator of willingness to pay for environmental quality.     

Innovation for sustainable development: from environmental design to transition management

Society needs to adapt in order to provide the wealth that an increasing part of the world population is getting used to. We are on a track to ecological and resource collapse if actions are not taken soon. Technology will have to play a key role in the process of changing industrial society. But innovation has to be embedded in social and organizational innovation. We need sociotechnical change. Environmentally conscious design has been practiced in engineering design for more than a decade. Its merits are sometimes blamed as futile, as the world has not witnessed a significant contribution to the solution of the larger (global) problems. This paper first sketches a scheme of the various levels of technological change, ranging from: (1) incremental optimizations of single artifacts, to (2) major change of artifacts, (3) systems change, and (4) technological transitions (involving changes in production and consumption). It outlines the stakeholders involved in these types of innovations and the parties that could orchestrate the innovation process. In this paper, It is argued that the most encompassing level of technological innovation, the level of transition, is crucial for achieving long-term sustainable development, as it has the largest potential for improvement. However, transition is not very well manageable. The paper contains a review of the literature regarding the occurrence of technological transitions. After a transition has occurred, the new system is often not efficient. Its gains in terms of diminished resource consumption or pollution have to be enlarged by less encompassing innovation strategies, such as systems innovations and product optimization. Transitions for sustainable development are often impossible, as the new systems have to compete with fully developed and optimized systems that have far advanced at the learning curve, i.e., are optimized by various systems and incremental innovations. Less encompassing levels of innovation, even those that aim at more sustainability, can counteract transitions that have more potential for sustainable development by improving the competing (unsustainable) technology. The paper will give several examples of this dilemma and some guidelines for developing government policies as well as corporate strategies. On the policy level, it is argued that it is especially important to develop (scope for) market niches for new sustainable systems and products as they create scope for experiments that could lead to transitions.

Climate change and variability in Sub-Saharan Africa: a review of current and future trends and impacts on agriculture and food security

Sub-Saharan Africa has been portrayed as the most vulnerable region to the impacts of global climate change because of its reliance on agriculture which is highly sensitive to weather and climate variables such as temperature, precipitation, and light and extreme events and low capacity for adaptation. This article reviews evidence on the scope and nature of the climate change challenge; and assesses the impact of climate change on agriculture and food security in Sub-Saharan Africa. From the review, it is apparent that the climate in Africa is already exhibiting significant changes, evident by changes in average temperature, change in amount of rainfall and patterns and the prevalence of frequency and intensity of weather extremes. The review also revealed that although uncertainties exist with regards to the magnitude of impacts, climate will negatively affect agricultural production in Sub-Saharan Africa. Specifically, as result of current and expected climate change, the area suitable for agriculture, the length of growing seasons and yield potential, particularly along the margins of semi-arid and arid areas, are expected to decrease. These impacts will affect all components of food security: food availability, food accessibility, food utilisation and food stability and hence increase the risk of hunger in the region. The review thus confirms the general consensus that Sub-Saharan Africa is the most vulnerable region to climate change. It suggests that, policymakers and development agencies should focus on formulating and implementing policies and programmes that promote farm level adaptation strategies currently being practiced by farmers across the region.     

Biodiversity conservation: From ecosystem to the ecosystem approach

The possibility of implementing 12 principles of the ecosystem approach is considered with regard to the results of meetings of the Conference of the Parties to the Convention on Biological Diversity (CBD) and recent international forums. The importance of these principles for achieving the main goals of the CBD is shown, and the role of biosphere reserves in solving urgent problems of biodiversity conservation and sustainable development in adjoining territories of subjects of the Russian Federation is discussed.
