Sustainable cooking energy options for rural poor people in India: an empirical study

Currently, energy consumption for cooking in rural households of India is mostly based on fuelwood used in traditional stoves. This paper presents results of a study carried out in a forest fringe area of India on cooking energy use. The concept of calculating levelized cost as cost per unit of useful energy is applied on source–device combinations of cooking and validated in Bargaon Community Development Block of Sundergarh District in Odisha, India. About 92 % of the households in the study area use fuelwood as the only energy source for cooking; the total use of fuelwood for only cooking, in the Block is nearly 1.8 times the total sustainable wood supply showing an urgent need for promoting alternative cooking energy options. This paper also presents an assessment of different cooking options in terms of cost per unit of useful cooking energy. LPG, biogas and gasifier stoves are found to be far too expensive for the local people. Briquette-fired improved stoves appear to be a promising cooking energy option in the study area. Government support and intervention are recommended for promoting this option.     

Power and politics of social–ecological regime shifts in the Chilika lagoon,India and Tam Giang lagoon,Vietnam

Analyses of ecological regime shifts primarily focus on abrupt, long-term and significant changes that trigger fundamental reorganisation in ecosystem structure and function. There remains limited empirical work on the relationship between regime shifts and social inequities, power imbalances, and social and environmental injustices. Inadequate attention to this social context restricts our ability to predict and avert impending regime shifts, or to effectively navigate where thresholds have been crossed. In this paper, we offer an initial empirical assessment of politics and power in two coastal lagoons in India and Vietnam experiencing abrupt change. We adopt a realist view of power to: (1) assess the social relations structuring human–environment interactions in both lagoons; (2) characterise the dominant framings and narratives that influence if and how regime shifts are understood; (3) consider who wins and loses if and when regime shifts and other forms of rapid environmental change take place; and (4) reflect on the implications of power and politics for the governance of regime shifts in linked human–ocean settings.     

应对气候变化需以生态文明理念构建全球技术合作体系

气候变化是人类发展过程中遇到的最大全球性环境问题,也是最大的外部性问题。IPCC报告显示,实现本世纪末温度升高不超过2度的目标,需要全球经济和能源系统深度的低碳转型,并在本世纪下半叶达到温室气体的净零排放。应对气候变化因此面临着前所未有的技术创新与合作需求。2015年底达成的《巴黎协定》提出了落实技术开发与转让的长期愿景,主张对气候变化领域的技术创新给予政策和资金支持,使发展中国家在技术周期的早期阶段就能够获取必要的技术,从而为实现全球应对气候变化提供保障。然而,基于工业文明的传统技术创新与合作模式难以满足保护全球气候的技术需求。减缓与适应技术是气候变化挑战下全球命运共同体的公共财富。为保证其足够的供应,必须超越追求私人利益最大化的狭隘,基于生态文明理念构建全球应对气候变化的新型技术合作体系。其核心是:实现多赢的合作目标,遵循"生态人"的合作原则,体现协同的合作内容,基于互信的合作形式,鼓励多元主体的参与,促进合作成果的分享。中国作为新兴发展中大国,对应对气候变化技术国际合作有多元的利益需求。为有效落实《巴黎协定》,亟需以加速国际合作为契机,积极谋划中国应对气候变化技术对外合作的总体方略和具体行动,有针对性地制定与发达国家、其他发展中国家及欠发达国家间优势互补的合作计划,探索并引导"南-北-南"三方技术合作等新形式。     

How do we assess vulnerability to climate change in India? A systematic review of literature

In countries like India where multiple risks interact with socio-economic differences to create and sustain vulnerability, assessing the vulnerability of people, places, and systems to climate change is a critical tool to prioritise adaptation. In India, several vulnerability assessment tools have been designed spanning multiple disciplines, by multiple actors, and at multiple scales. However, their conceptual, methodological, and disciplinary underpinnings, and resulting implications on who is identified as vulnerable, have not been interrogated. Addressing this gap, we systematically review peer-reviewed publications (n = 78) and grey literature (n = 42) to characterise how vulnerability to climate change is assessed in India. We frame our enquiry against four questions: (1) How is vulnerability conceptualised (vulnerability of whom/what, vulnerability to what), (2) who assesses vulnerability, (3) how is vulnerability assessed (methodology, scale), and (4) what are the implications of methodology on outcomes of the assessment. Our findings emphasise that methods to assess vulnerability to climate change are embedded in the disciplinary traditions, methodological approaches, and often-unstated motivations of those designing the assessment. Further, while most assessments acknowledge the importance of scalar and temporal aspects of vulnerability, we find few examples of it being integrated in methodology. Such methodological myopia potentially overlooks how social differentiation, ecological shifts, and institutional dynamics construct and perpetuate vulnerability. Finally, we synthesise the strengths and weaknesses of current vulnerability assessment methods in India and identify a predominance of research in rural landscapes with a relatively lower coverage in urban and peri-urban settlements, which are key interfaces of transitions.

应对气候变化关键技术创新差异的时空格局——以“一带一路”沿线国家为例

技术是应对气候变化的重要手段,关键技术创新差异的扩大将不利于各国应对气候变化的协同发展。以技术产出的专利为数据源,运用大数据挖掘工具、泰尔熵指数及空间计量学的方法和理论,分析了"一带一路"沿线国家应对气候变化关键技术创新差异的时空格局演变情况。研究结果表明:(1)沿线国家应对气候变化关键技术创新差异整体上呈现下降态势,并以初期震荡向后期平稳有升过度。(2)按地理位置划分的区域技术创新差异呈现高的空间集聚效应,且强强集聚与弱弱集聚具有一定时期内的稳定性,部分地区面临陷入技术贫困陷阱风险。(3)沿线各国应对气候变化技术创新差异存在趋同俱乐部现象,个别国家随时间推移可能经历不同俱乐部过度。针对这种趋同特征及各国技术需求特点可划分为4种类别:技术转出区、技术转入区、技术扩散区和技术承接区。技术转出区多集中在东欧某些经济发达、能源依存度高的国家。为此,本文提出如下建议:(1)各国根据自身情况制定减排政策的同时,需要国际社会制定与其相适应的差异化且有侧重的援助方案。(2)技术创新强国在涉及应对气候变化技术转移知识产权等事项上应该给予技术需求国让步。同时,技术转移应考虑区域协同及地理邻近的扩散。(3)中国应发挥好南南合作援助基金的作用,加强特定区域内共性技术的帮扶力度,建立与适宜国家间关键技术联合研发与示范机制,树立大国形象。(4)中国应加快沿线战略布局,根据不同区域各国应对气候变化的现状及其技术能力制定差异化的产业和技术转移的政策,加强与沿线国家的技术合作与贸易往来,形成优势互补的产业链。     

Human ecological effects of tropical storms in the coastal area of Ky Anh (Ha Tinh,Vietnam)

Vietnam is prone to tropical storms. Climate change effects contribute to sea level rise, floods, progression of the low water line and coastal erosion. This paper inventories the perception of local people, assesses and values main aspects of the livelihood damage caused by the tropical storms of the period 2008–2013 in three coastal communes of the Ky Anh District of the Ha Tinh Province in Central Vietnam. The communes were selected because the location of their coastal line is perpendicular to the storm itself, which made them prone to damage. The effects of increasingly extreme weather conditions on three communities in an area most affected by storms and floods on the local residents and their responses to these changing environmental conditions are analyzed and assessed. The results of questionnaires completed by randomly selected local inhabitants of these communes show that storms and related hazards such as flood, sea level rise and heavy rain are perceived as the most impacting climate change intensified phenomena on agriculture and aquaculture, livestock, household property and income. Opinions and measured data provided by the commune and district authorities allow estimating the total direct cost of the tropical storm at 1.56 million $US (The used conversion rate VND/$US is 21,730 when the research was conducted in 2014) during the period 2008–2013. The long-term costs of adaptation and social impact measures will be significantly higher. Details of the monetary figures allow identifying the physical and natural capital of the area as being most affected by the storm. Trend and cost analysis show that the total financial support for hazard prevention and management during 2014–2019 is estimated at 1.19 up to 1.32 million $US. Local stakeholders indicate that climate change adaptation should not be limited to technical measures such as strengthening dikes, but also should target planting protection forests and mangroves and land use planning. Financial support for the relocation policy, stakeholder involvement and integrating climate change adaptation in both the socioeconomic development master plan and local land use planning are also of importance.     

Sustainability assessment of water governance alternatives: the case of Guanacaste Costa Rica

Many new forms of water governance are emerging in response to economic and social needs and wants, as well as water-related problems such as scarcity, injustice, and conflict. However, there is little evidence on how sustainable these governance regimes are, which would be critical for making progress toward sustainable and just water governance. In this article, we present the results of a transdisciplinary multi-criteria sustainability assessment of alternative governance regimes for Guanacaste Province, Costa Rica. The assessment specifies differences between sustainable and unsustainable governance regimes, while also pinpointing how the current water governance regime performs in comparison to those alternatives. The findings indicate that those governance regimes with just and deliberative stakeholder involvement, secure groundwater reserves, and healthy dry tropical ecosystems were considered sustainable and just. In contrast, the current state of water governance was found to be at high risk of digressing toward unsustainable systems where rural communities lack rights and influence, where economies favor agro-industry and high impact tourism at the expense of rural livelihoods, and where water scarcity overwhelms weak governance. This assessment study clarifies water sustainability goals, asserts the need for transformational change, and offers a pragmatic foundation for actions toward sustainable water governance.     

Combating climate change calls for a global technological cooperation system built on the concept of ecological civilization

Climate change has been considered as the most paramount global environmental problem and the biggest externality throughout the history of human development. Accordingly, the world is facing unprecedented technological innovation and collaborative demands to deal with climate change. In the 2015 Paris Agreement, a long-term vision of technology development and transfer implementation was proposed, and policy and financial support for technological innovation in the area of climate change was advocated. These terms aim to enable developing countries to acquire the necessary technology in the early stage of the technology cycle to address climate change challenge. However, the traditional technological innovation and cooperation mode based on industrial civilization can hardly meet the technical demands of global climate protection. To ensure the continuous development and deployment of technology in a required scale and pace, a new global technical cooperation system is proposed to develop based on the philosophy of ecological civilization. The core contents of this system are supposed be as follows: to implement all-win cooperation targets, adhering to cooperation principles of Eco-man, adopt cooperation content that reflects synergy, pursue cooperation based on mutual trust, encourage participation of multiple actors, and promote sharing of cooperative outputs.     

Against the current: rewiring rigidity trap dynamics in urban water governance through civic engagement

This paper investigates how the agency of local residents can affect persistent and unsustainable practices in urban water supply governance. Using a case study from Bangalore, India, we analyze a social–ecological trap which developed after a shift to external water provision paired with rapid urbanization. The reluctance of forsaking initial investments in infrastructure and competence, and the subsequent loss of the local network of lakes built for harvesting rainwater, reinforced dependence on external sources while undermining groundwater levels in the city. These feedbacks made water scarcity a structurally persistent feature of Bangalore. This situation started to change when local residents recently started organizing to preserve and restore Bangalore’s lakes. By entering collaborative management agreements with municipal authorities, these lake groups have restored and established effective protection of five lakes. Through a case study of this civic engagement we show that the lake restorations have the potential to counteract trap mechanisms by restoring ecological functions, and by reducing water scarcity as groundwater levels rise and authorities are relieved from maintenance and monitoring tasks. Importantly, these lake groups have also created opportunities for over a dozen similar groups to form across the city. This demonstrates that social movements can be an important source of change in social–ecological traps.     

Relationship between carbon emissions and economic development: case study of six countries

There is much discussion within the sustainable development community regarding climate stabilization and particularly, finding environmentally equitable ways to address emission reductions. Knowing the current level of emission is only one variable in this complex picture. While the rate of emissions is clearly a problem, the overall increase in GHG concentration in the atmosphere is ultimately the main driver of anthropogenic warming. Therefore, it is also important to understand the cumulative emissions, those which have taken us to the current condition. This research presents a case study of six countries to compare the emissions per capita and cumulative emissions during the past 200 years. It is known that carbon emissions are closely related to economic activities, but here we show that some countries have reached per capita emissions plateaus at different levels while others are still rising. Specifically, one approach toward socioeconomic development, in terms of energy–economy, reaches a plateau at 10 Mt carbon per person, which the United Kingdom and South Korea have attained. The US occupies another emission regime at 20 Mt carbon per person. Developing economies such as India and China are considerably below these levels, and unless they follow other integrated economic/environmental solutions, they will continue to increase their per capita emissions during development.     

Spreading the News on Carbon Capture and Storage: A State-Level Comparison of US Media

Carbon capture and storage (CCS) has received abundant federal support in the USA as an energy technology to mitigate climate change, yet its position within the energy system remains uncertain. Because media play a significant role in shaping public conversations about science and technology, we analyzed media portrayal of CCS in newspapers from four strategically selected states. We grounded the analysis in Luhmann's theory of social functions, operationalized through the socio-political evaluation of energy deployment (SPEED) framework. Coverage emphasized economic, political/legal, and technical functions and focused on benefits, rather than risks of adoption. Although news coverage connected CCS with climate change, the connection was constrained by political/legal functions. Media responses to this constraint indicate how communication across multiple social functions may influence deployment of energy technologies.     

Towards a new climate economics:research areas and prospects

International cooperation to address climate change now stands at a crossroads.With a new international regime for emissions reduction established by the Durban Platform, "New Climate Economics(NCE)" has become a research hotspot.The need for urgent action to combat climate change has prompted discussion on reforms of economic growth patterns and the energy system.The industrial civilization,therefore,now faces a transition towards a new pathway for ecological sustainability.NCE explores new economic concepts,theories,and analytical methods to design a balanced pathway for sustainable growth and emission reduction.Instead of getting trapped in discussions on allocation of emission reduction responsibilities and obligations among countries,NCE pays more attention to developing win-win multilateral cooperation mechanisms that facilitate collaborative RD and knowledge sharing.In addition,NCE studies incentives for low-carbon transition,turning carbon emission reduction into a domestic need for countries to increase their international competitiveness.To achieve the 2°C target,most countries around the world face challenges of insufficient emission allowances to cover expected emissions associated with their projected economic growth.As carbon emissions rights becomes an increasingly scarce resource,increasing the carbon productivity of the economy turns to be the critical path to address the dilemma of green or growth.NCE studies the historical evolution of carbon productivity for countries at different development stages as well as ways to enhance such carbon productivity.This type of study provides invaluable lessons for emerging economies to reach their own emission peaks without losing the momentum of growth.Replacing fossil fuels with new and renewable energy has proven to be an inevitable choice for reshaping the energy system and addressing climate change- it has already become a global trend.NCE studies incentives for new energy technology innovation and deployment provided by carbon pricing,and sheds light on the co-benefits of climate change mitigation,such as resource conservation,environmental protection,and energy security.The role of carbon pricing in promoting intemational RD cooperation and technical transfer will also be studied.The shift in consumption patterns is another key factor enabling a low-carbon transformation.Therefore,NCE also explores the theoretical work on new values of wealth,welfare and consumption,new lifestyles in the context of ecological civilization,concepts and implementation of low-carbon urban planning in developing countries,and the impacts of consumption pattern changes on social development,material production,and urban infrastructure construction.     

前沿技术进步、技术效率和区域经济差距

采用1998-2009年中国30个省市的人均GDP与当年全国人均GDP的差值作为区域经济差距指标,运用核密度估计方法观察了我国区域经济差距的变动状况。从核密度图可知,我国区域经济呈现出收敛的态势;通过随机前沿模型从全要素生产率中分解出前沿技术进步和技术效率,利用1998-2009年28个省市的面板数据,检验了全要素生产率对区域经济差距的影响。实证结果显示,前沿技术进步能够显著的缩小区域经济差距,其中对于东部地区的效果较为显著,技术效率则能够扩大东部地区的经济差距,对于中部和西部地区的影响不显著。政策含义是缩小东部地区经济差距的主要途径是加大对科技创新领域的投入,加强对欠发达地区的技术支持;对于中部地区和西部地区而言,则应该是加大市场化水平、对外开放水平和地方支出比重。     

环境约束下中国地区能源全要素效率及其影响因素

当下中国经济发展面临以节约能源消费和减少CO2排放作为主要目标的经济结构转型压力。在能源约束条件下如何提高能源效率实现经济可持续增长,能源效率问题作为研究中国经济可持续增长是必要的且具有十分重要的现实意义。本文基于Metafrontier GML指数方法,构建动态综合的污染强度指标作为非期望产出,测算中国地区2004—2013年28个省份的绿色能源效率,进而对中国区域之间与区域内部技术效应进行分解,并对其收敛性和影响因素进行分析。研究结果发现,中国东部地区技术赶超、创新和领先效应是显著的,东部地区辽宁省技术"领先效应"并不明显,导致该地区能源效率并未有提高;中部地区的技术创新效应不明显,但能源效率均有明显提高;而西部地区只存在技术创新效应,此地区的技术前沿与全国范围的共同技术前沿差距较大,特别是此地资源型地区的技术改进效率不高。其次,通过对能源效率的σ收敛和β收敛进行检验,发现中国地区能源效率在2004—2013年存在σ收敛但是不存在绝对β收敛。再次,对影响能源效率的因素进行回归分析,结果发现技术"赶超效应"、"创新效应"和"领先效应"均对能源效率的提高存在正向作用,产业结构升级和能源价格对能源效率的提高存在促进作用,但是增强环境规制强度会抑制能源效率的提高。这就意味着提高能源效率,对于不同地区需要"因地制宜",特别是对于资源型地区,需加大促进技术创新政策力度,缩小地区技术前沿与全国技术前沿的距离,制定合理的环境规制政策,进而促进能源效率的提高。     

European electricity utilities managing energy transition challenges

Energy transitions are a complex technological-economic and social process. Currently, this involves the impact that innovation in technology and information as well as social practices can have on the way the energy is used. Therefore, business becomes much more complex and risky. In the particular case of the European Union, recent years were also marked by multiple changes at the political, economic, social and environmental context. Changes are already in course posing new challenges to European Electricity Utilities. The question that arises is how these subjects impact the structure, consolidation and governance of the electricity utilities and which drivers have the greatest impact on the speeding up the change. It is also our aim to understand how companies are responding to transition challenges in order to ensure the sustainability of their activities and their healthy stay in the market. In this article we present an insight of this issue through the analysis of thirteen indicators on the seven largest European energy utilities. Results allowed comprising the effects of the different economic and financial contexts on the variables under study.     

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.     

Upscaling of business model experiments in off-grid PV solar energy in India

Rapidly developing countries like India face numerous challenges related to social and environmental sustainability, which are associated with their fast economic growth and rising energy demand, climate change, and widening disparities between the rich and the poor. Recently, a number of claims have been made in the literature that the prospects of alternative development pathways in emerging economies in Asia are becoming more likely, and that these economies might even leapfrog Western initiatives. This paper contributes by reporting on the five most visible and established initiatives in the area of off-grid PV solar energy in India, specifically homing in on the innovative business models that are evolving. We develop a new typology of upscaling dimensions in order to analyze these five initiatives. They are found to be quite successful, but have difficulty in terms of reaching the poorest of the poor (deep upscaling) and bringing about required institutional change (institutional upscaling).     

Impacts of climate change on Chinese ecosystems: key vulnerable regions and potential thresholds

China is a key vulnerable region of climate change in the world. Climate warming and general increase in precipitation with strong temporal and spatial variations have happened in China during the past century. Such changes in climate associated with the human disturbances have influenced natural ecosystems of China, leading to the advanced plant phenology in spring, lengthened growing season of vegetation, modified composition and geographical pattern of vegetation, especially in ecotone and tree-lines, and the increases in vegetation cover, vegetation activity and net primary productivity. Increases in temperature, changes in precipitation regime and CO₂ concentration enrichment will happen in the future in China according to climate model simulations. The projected climate scenarios (associated with land use changes again) will significantly influence Chinese ecosystems, resulting in a northward shift of all forests, disappearance of boreal forest from northeastern China, new tropical forests and woodlands move into the tropics, an eastward shift of grasslands (expansion) and deserts (shrinkage), a reduction in alpine vegetation and an increase in net primary productivity of most vegetation types. Ecosystems in northern and western parts of China are more vulnerable to climate changes than those in eastern China, while ecosystems in the east are more vulnerable to land use changes other than climate changes. Such assessment could be helpful to address the ultimate objective of the United Nations Framework Convention on Climate Change (UNFCCC Article 2).     

Social acceptance of wind and solar power in the Brazilian electricity system

Renewable energy is often associated with the production of clean electricity and free of significant adverse impacts. However, several studies have been highlighting the importance of the assessment of social impacts of these technologies, including not only the benefits but also the potential negative aspects most frequently affecting local population. The energy matrix in Brazil is already built up on a renewable system largely supported on hydropower but other technologies with special emphasis on wind power start to have a major role, with a strong growth forecasted for this sector in the coming years. This article discusses the integration of solar and wind power in the Brazilian electricity system focusing on the social awareness and acceptance for the population living in high potential regions. For this, a questionnaire was proposed with the aim of evaluating the level of knowledge of wind and solar power, their social acceptance and perceptions towards cost, local development and environmental impacts. The questionnaire was implemented in an academic institution in the State of Rio Grande do Norte (RN) including students and professors as key actors for the present and future energy policy decision making. The implementation process and the obtained results are described allowing to conclude on the high level of acceptance of solar and wind power in the country and the region, with low evidence of not in my backyard syndrome.
