Understanding and managing climate change: the UK experience     

Mike Hulme  John Turnpenny 《The Geographical journal》2004,170(2):105-115

Climate change has emerged over the last 25 years not just as a physical reality, affecting global and regional climates, but also as a socio-cultural phenomenon – an icon of a globalizing world which is increasingly altering the physical fabric of our planet and at the same time demanding new forms of global governance. The UK, both through its scientific research activity and through its development of climate change policy initiatives, has been at the forefront of this emergence. This review traces some of this history from a UK perspective, with an emphasis on the last 10 years. The relationship between climate change science and policy has become increasingly reflexive, leading to new forms of research and institutional structures. The academic discipline of geography has been rather marginalized from this process.  相似文献   

The status of Earth Observation (EO) & Geo-Information Sciences in Africa – trends and challenges     

Tsehaie Woldai 《地球空间信息科学学报》2020,23(1):107-123

ABSTRACT

Over the last 20 years, Africa has witnessed a slow but steady advancement in space-based technologies as they are increasingly recognized as an essential tool for decision-making that can leapfrog African development. A critical review on the outcome of a survey questionnaire focused on African private sector industries and universities, services and education/training in EO and Geo-Information Sciences, combined with literature review, and personal contacts reveal optimism for success in four sectors. These include the public sector (Government ministries and departments); Academic institutions (universities/colleges/national or regional centers); and space agencies and private sector companies. These sectors are intertwined and fundamental for creating an enabling environment for solutions to a broad spectrum of pressing priorities: job creation, poverty alleviation, and sustainable resource management. The result shows that there is an uptake in the number of institutions and market segments created. To date, there are more than 90 academic institutions and over 53 national space agencies in 28 countries. Within the 53 national space agencies, 11 African countries have already launched a total of 36 satellites into orbit, and additional five are expected by the first quarter of 2021; another five by 2025; thus, amounting to 46 satellites not foreseen ten years ago. In addition, there are now ten receiving and tracking stations in six African countries and 17 scientific National Associations or Societies with specialized expertise in Geo-Information technologies. The updated survey on the private sector in 2019 ascertained that around 4110 people are working in 130 of the 229 EO and Geo-Information Science companies identified in Africa. Ongoing investigations reiterate that companies dealing with space-based datasets and Geo-Information Sciences together with the private spin-off companies today absorb more than 15,000 people and the assumption is that this number is going to exceed 100,000 by the year 2025.  相似文献   

Exploratory analyses of local institutions for climate change adaptation in the Mongolian grasslands: An agent-based modeling approach     

Jun Wang  Daniel G. Brown  Rick L. Riolo  Scott E. Page  Arun Agrawal 《Global Environmental Change》2013,23(5):1266-1276

There has been a decrease in grazing mobility in the Mongolian grasslands over the past decades. Sedentary grazing with substantial external inputs has increased the cost of livestock production. As a result, the livelihoods of herders have become more vulnerable to climate variability and change. Sedentary grazing is the formal institutional arrangement in Inner Mongolia, China. However, this may not be an efficient institutional arrangement for climate change adaptation. Self-organized local institutions for climate change adaptation have emerged and are under development in the study area. In this study, we did exploratory analyses of multiple local institutions for climate change adaptation in the Mongolian grasslands, using an agent-based modeling approach. Empirical studies from literature and our field work show that sedentary grazing, pasture rental markets, and reciprocal pasture-use groups are three popular institutional arrangements in the study area. First, we modeled the social–ecological performance (i.e., livelihood benefits to herders and grassland quality) of these institutions and their combinations under different climate conditions. Second, we did exploratory analyses of multiple social mechanisms for facilitating and maintaining cooperative use of pastures among herders. The modeling results show that in certain value-ranges of some model parameters with assumed values, reciprocal pasture-use groups had better performance than pasture rental markets; and the comparative advantage of cooperative use of pastures over sedentary grazing without cooperation becomes more evident with the increase in drought probability. Agent diversity and social norms were effective for facilitating the development of reciprocal pasture-use groups. Kin selection and punishments on free-riders were useful for maintaining cooperation among herders.  相似文献   

The Regionalization of Chinese Business Networks: A Study of Singaporean Firms in Hainan,China     

Chia‐Zhi Tan  Henry Wai‐chung Yeung 《The Professional geographer》2000,52(3):437-454

This paper examines the central role of social and political institutions behind motivations and strategies of ethnic Chinese Singaporean investment in Hainan, China. Drawing upon 22 case studies of Singaporean firms in Hainan, we show that Singaporean investment in Hainan is embedded in Chinese business networks and their associated institutions. At the personal level, direct investments are largely motivated by the cultural attachments of Singaporean Hainanese to Hainan. Their small‐ and medium‐sized joint ventures largely reflect the characteristics of ethnically‐based Chinese business networks that stress connections, or guanxi. Similarly, the influence of social organizations (e.g., clan associations) and government institutions (e.g., public and quasi‐public agencies) on Singaporean investment strategies in Hainan reveals the significance of ongoing social relations institutionalized at the broader societal level.  相似文献   

世界城市中的跨国机构研究综述     

梅琳  薛德升 《地理科学进展》2012,31(10):1264-1273

在全球化的冲击下, 超越或嵌入国家地理疆界范围的行动者改变着世界政治地理格局。国际组织、国际非政府组织、跨国政府组织和跨国非政府组织等跨国机构在全球地缘政治中的角色越来越重要。地理学视角的研究认为, 不同类型的跨国机构在全球尺度上创造了复杂而多样化的全球政治地理结构, 也形成具有政治特色的世界城市体系。不仅如此, 跨国机构通过地方尺度的行动, 深入城市的全球化发展过程, 成为与世界城市紧密关联的影响因子, 对城市制度和内部空间等方面的变化发挥着不可忽视的作用。对当代西方地理学中跨国机构研究进行梳理和评述, 在此基础上指出目前存在的不足, 不仅是从地理学视角对跨国机构研究进展的把握, 也希望对中国当代政治地理和城市地理中跨国机构的研究有一定的借鉴和启示意义。  相似文献   

金融机构空间集聚与经济增长——来自广东省县域的实证检验     

周天芸  王莹 《地理研究》2014,33(6):1119-1128

基于对国内外金融发展与经济增长关系研究的详细梳理,运用广东县域的数据进行研究,为金融机构空间集聚的重要性及金融机构空间集聚促进经济增长提供论证。研究表明：金融机构的空间集聚与广东县域经济增长存在倒U型关系,机构集聚初期与经济增长呈正向关系,随着机构集聚的增强,这一相关性逐渐减弱。金融机构集聚能部分解释广东省县域经济增长的差异;同时,广州作为金融机构空间集聚的区域中心,影响着广东县域的金融机构空间集聚与经济增长的关系。  相似文献

Changing conflict resolution institutions in the Ethiopian pastoral commons: the role of armed confrontation in rule-making     

Jon D. Unruh 《GeoJournal》2005,64(3):225-237

Pastoralist access and use of common grazing resources in the Horn of Africa increasingly include armed confrontation over diminishing resources and reduced access. This comes about as traditional customary institutions (sets of rules) for commons management become compromised due to the presence of outside influences and actors which significantly change both resource availability, and conceptions about who is subject to traditional rules governing commons – particularly rules associated with exclusion. At the same time a combination of local knowledge regarding what happens to open access commons (degradation), a reluctance to give up control of commons and associated ways of life, and armed conflict as a viable alternative for exclusion rules, provide for combative situations and large costs. While a great deal of valuable work has been accomplished regarding the derivation of effective institutions to better manage commons, situations of armed conflict can seem particularly distant from effective rule-making, because few institutions can endure the stresses of armed conflict. Recent developments in Ethiopia however suggest an unexpected proximity between armed confrontation and the prospect for commons management rule-making. With examples from the Afar, Somali and Karamojong Cluster pastoralists, this paper examines the ingredients for rule-making in combative commons situations. Specific coincident forms of state recognition, donor flexibility, perceptions of the cost of conflict, and the local to international reaction to these, are examined for their utility and limitations in the provision of a facilitating context for institution derivation for commons management.  相似文献   

Climate change and the water–energy–food nexus: insights from policy and practice in Tanzania     

Joanna Pardoe  Declan Conway  Emilinah Namaganda  Katharine Vincent  Andrew J. Dougill  Japhet J. Kashaigili 《Climate Policy》2018,18(7):863-877

The threat of climate change is emerging at a time of rapid growth for many economies in sub-Saharan Africa (SSA). Dominant narratives comprising ambitious development plans are common and often based around sectors with strong inter-dependencies that are highly exposed to climate variability. Using document analysis and key informant interviews, this article examines how climate change is addressed in policy, how it is being mainstreamed into water, energy and agriculture sector policies and the extent to which cross-sectoral linkages enable coordinated action. These questions are addressed through a case study of Tanzania, highlighting broader lessons for other developing countries, particularly those in SSA facing similar challenges. The article finds that, while the agriculture and water sectors are increasingly integrating climate change into policies and plans in Tanzania, practical coordination on adaptation remains relatively superficial. Publication of the Tanzania National Adaptation Plan of Action (NAPA) in 2007 marked a step change in the integration of climate change in sectoral policies and plans; however, it may have reinforced a sectoral approach to climate change. Examining the policies for coherence highlights overlaps and complementarities which lend themselves to a coordinated approach. Institutional constraints (particularly structures and resources) restrict opportunities for inter-sectoral action and thus collaboration is confined to ad hoc projects with mixed success to date. The results highlight the need for institutional frameworks that recognize and address these constraints to enable development goals to be pursued in a more sustainable and climate-resilient manner.

KEY POLICY INSIGHTS

• The NAPA has been successful at encouraging climate change mainstreaming into sectoral policies in Tanzania; however, the cross-sectoral collaboration crucial to implementing adaptation strategies remains limited due to institutional challenges such as power imbalances, budget constraints and an ingrained sectoral approach.

• Collaboration between nexus sectors in Tanzania is largely through ad hoc projects with limited progress on establishing deeper connections to enable collaboration as a process. Regular cross-sectoral planning meetings and consistent annual budgets could provide a platform to enhance cross-sectoral coordination.

• Plans to develop hydropower and agriculture are prevalent across sub-Saharan Africa. Insights from Tanzania highlight the importance of institutional and policy frameworks that enable cross-sectoral coordination.

African Inland Fisheries: Experiences with Co-Management and Policies of Decentralization   总被引：1，自引：1，他引：0  

Roger Lewins  Malloum Ousman Baba  Emma Belal  Steve Donda  Abbagana Mamane Lamine 《社会与自然资源》2014,27(4):405-420

Most countries in Africa have promoted some form of decentralized fisheries management either as discrete co-management projects or as a component of broader decentralization processes that cut across other sectors. These initiatives were shaped by an international policy narrative that emphasises participation in decision making and development. A review of fisheries decentralization experiences in Cameroon, Niger, Nigeria, and Malawi reveals marked differences in purpose, strategy, and performance. In general, co-management projects are limited by their ability to scale up new practice and to maintain viable and representative management institutions. In other cases, the decentralization process is not well supported politically or locally or does not articulate with fisheries policy. Experiences of decentralization in other sectors provide useful lessons. Acknowledging the informal institutional environment or realpolitikof fisheries and the rural economy could provide opportunities to better manage and review the process of decentralization.  相似文献
