Including animal to plant protein shifts in climate change mitigation policy: a proposed three-step strategy     

Helen Harwatt 《Climate Policy》2019,19(5):533-541

Strong and rapid greenhouse gas (GHG) emission reductions, far beyond those currently committed to, are required to meet the goals of the Paris Agreement. This allows no sector to maintain business as usual practices, while application of the precautionary principle requires avoiding a reliance on negative emission technologies. Animal to plant-sourced protein shifts offer substantial potential for GHG emission reductions. Unabated, the livestock sector could take between 37% and 49% of the GHG budget allowable under the 2°C and 1.5°C targets, respectively, by 2030. Inaction in the livestock sector would require substantial GHG reductions, far beyond what are planned or realistic, from other sectors. This outlook article outlines why animal to plant-sourced protein shifts should be taken up by the Conference of the Parties (COP), and how they could feature as part of countries’ mitigation commitments under their updated Nationally Determined Contributions (NDCs) to be adopted from 2020 onwards. The proposed framework includes an acknowledgment of ‘peak livestock’, followed by targets for large and rapid reductions in livestock numbers based on a combined ‘worst first’ and ‘best available food’ approach. Adequate support, including climate finance, is needed to facilitate countries in implementing animal to plant-sourced protein shifts.

Key policy insights

• Given the livestock sector’s significant contribution to global GHG emissions and methane dominance, animal to plant protein shifts make a necessary contribution to meeting the Paris temperature goals and reducing warming in the short term, while providing a suite of co-benefits.

• Without action, the livestock sector could take between 37% and 49% of the GHG budget allowable under the 2°C and 1.5°C targets, respectively, by 2030.

• Failure to implement animal to plant protein shifts increases the risk of exceeding temperate goals; requires additional GHG reductions from other sectors; and increases reliance on negative emissions technologies.

• COP 24 is an opportunity to bring animal to plant protein shifts to the climate mitigation table.

• Revised NDCs from 2020 should include animal to plant protein shifts, starting with a declaration of ‘peak livestock’, followed by a ‘worst first’ replacement approach, guided by ‘best available food’.

Implementing climate change adaptation: lessons from India’s national adaptation fund on climate change (NAFCC)     

Ravi S. Prasad 《Climate Policy》2019,19(3):354-366

With poverty alleviation and sustainable development as key imperatives for a developing economy like India, what drives the resource-constrained state governments to prioritize actions that address climate change impacts? We examine this question and argue that without access to additional earmarked financial resources, climate action would get overshadowed by developmental priorities and effective mainstreaming might not be possible. A systematic literature review was carried out to draw insights from the current state of implementation of adaptation projects, programmes and schemes at the subnational levels, along with barriers to mainstreaming climate change adaptation. The findings from a literature review were supplemented with lessons emerging from the implementation of India’s National Adaptation Fund on Climate Change (NAFCC). The results of this study underscore the scheme’s relevance.

Key policy insights

• Experience with NAFCC implementation reveals that states require sustained ‘handholding’ in terms of financial, technical and capacity support until climate change issues are fully understood and embedded in the policy landscape.

• Domestic sources of finance are critically important in the absence of predictable and adequate adaptation finance from international sources.

• The dedicated window for climate finance fosters a spirit of competitive federalism among states and encourages enhanced climate action.

• Enhanced budgetary allocation to NAFCC to strengthen the state-level adaptation response and create capacity to mainstream climate change concerns in state planning frames, is urgently needed.

Cross-site analysis of perceived ecosystem service benefits in multifunctional landscapes     

《Global Environmental Change》2019

Rural development policies in many Organization for Economic Co-operation and Development (OECD) member countries promote sustainable landscape management with the intention of providing multiple ecosystem services (ES). Yet, it remains unclear which ES benefits are perceived in different landscapes and by different people. We present an assessment of ES benefits perceived and mapped by residents (n = 2,301) across 13 multifunctional (deep rural to peri-urban) landscapes in Europe. We identify the most intensively perceived ES benefits, their spatial patterns, and the respondent and landscape characteristics that determine ES benefit perception. We find outdoor recreation, aesthetic values and social interactions are the key ES benefits at local scales. Settlement areas are ES benefit hotspots but many benefits are also related to forests, waters and mosaic landscapes. We find some ES benefits (e.g. culture and heritage values) are spatially clustered, while many others (e.g. aesthetic values) are dispersed. ES benefit perception is linked to people’s relationship with and accessibility to a landscape. Our study discusses how a local perspective can contribute to the development of contextualized and socially acceptable policies for sustainable ES management. We also address conceptual confusion in ES framework and present argumentation regarding the links from services to benefits, and from benefits to different types of values.  相似文献   

我国资源利用现状及节约机制框架的构建   总被引：1，自引：0，他引：1  

苑韶峰 《地域研究与开发》2007,26(1):50-53

对于资源的态度无非"开源"、"节流"2种,"开源"由于其较高的成本和有限性使得"节流"逐渐受到人们的重视.资源的可持续性是一个长期困扰人类的全球性问题,尤其对我国这样的人多地少、资源匮乏的国度而言,更是关系到生存与发展的迫在眉睫的问题.在分析了我国能源、水、土地、矿产等资源利用特点及供求矛盾的基础上,提出了对我国建设资源节约型社会的关键是有效地激励与约束机制的观点,并且构建了从法律法规、政策、经济、监督等角度建立约束机制,从产权、经济和声誉的角度建立激励机制的思路.  相似文献   

Developing a building policy for the erosion zone: Solutions to some key (Dutch) questions     

P.R. Winckel  J.K. Vrijling  J. van de Graaff 《Coastal Engineering》2008

In those coastal communities where the most seaward strip of mainland consists of dunes, these dunes often serve as a flexible sea defence. In addition, this strip offers large potential for housing and commercial enterprises. Unfortunately, due to severe storm surges part of this strip (the erosion zone) is subject to erosion, and as a result of which any buildings or infrastructure located here, are destroyed. Therefore, as we will illustrate in this paper, a building policy for this zone should reflect a compromise between two opposite interests: exploitation of the existing potential and, prevention of an unacceptable high risk due to erosion. Accordingly, the authors have developed a framework for such a building policy on the basis of which the desirability of various different types of investments and the location within the erosion zone of such investments can be determined. The examples that are used to illustrate this framework in this paper are limited to experiences in The Netherlands as relevant data and experiences are available and relatively easy accessible here. Nevertheless, the approach as is described is generic and applicable worldwide suggesting that the discovered unused potential for exploitation is not just limited to The Netherlands.  相似文献

Entrepreneurial causation and effectuation logics in a regional context: Assessing the importance of population density     

Jarle Aarstad  Stig-Erik Jakobsen 《Norsk geografisk tidsskrift. Norwegian journal of geography》2019,73(5):290-300

ABSTRACT

The purpose of the article is to assess whether an entrepreneurial causation or effectuation logic is a function of geographical location in densely populated economic regions versus sparsely populated economic regions. A causation logic implies that the entrepreneur primarily focuses on a predefined goal and further aims to identify the means to reach that goal. By contrast, an effectuation logic implies that the entrepreneur to a larger extent focuses on the means at hand, which she or he aims at materialising into one or more goals that are not necessarily predefined. The empirical data for the study are based on an investigation and evaluation of Norwegian entrepreneurs in business incubation that are located in many different economic regions of the country. Multilevel regression analyses showed that geographical location in sparsely populated economic regions is associated with a causation logic, whereas a location in densely populated economic regions is associated with an effectuation logic. An implication of the article is that entrepreneurial stakeholders, such as policymakers, incubator managers, public and private partners, and entrepreneurs themselves should be aware of differences in causation and effectuation logics between entrepreneurs located in densely versus sparsely populated economic regions.  相似文献   

Circulating planning ideas from the metropole to the colonies: understanding South Africa's segregated cities through policy mobilities     

Astrid Wood 《Singapore journal of tropical geography》2019,40(2):257-271

In the early part of the twentieth century, South African cities were segregated in accordance with British city planning concepts that embodied the belief that social order can be manipulated through the urban form. This paper surveys the history of South African planning practices to understand the spread of segregation policies and practices. Whereas scholars tend to agree that the apartheid city (post?1948) is a more highly organized and structured version of the colonial city (pre?1910), the literature lacks consensus on the development of the segregated city (1910?1948) within South Africa. How did concepts of segregation circulate and why was it implemented with such consistency? Accordingly, this paper employs concepts of policy mobilities to trace historical configurations in South Africa to international influences. The focus on the circuits of knowledge explains how concepts and designs transplanted from elsewhere helped create the form of South African cities today. Understanding the movement of planning ideas through policy mobilities furthers geographical understandings of historical circulation processes, the role of the local actors, and policy mobilities failure. This history of learning also challenges the assumption that South African cities are unique and in so doing opens the doors for knowledge sharing between postcolonial cities.  相似文献   

中国土地利用/覆盖变化的生态环境安全响应与调控   总被引：31，自引：1，他引：30

中国从20世纪70年代末实施了前所未有的改革开放政策,巨大的境外投资、有偿转让使用与土地联产承包政策在广大城乡的推行,引致了快速的城市化与经济增长过程,城市化水平增长15%,GDP平均每年增长超过9%,城市化土地面积增长2%。与此相应,严重的生态环境灾害相继发生,1994年淮河特大污染事件;1997年黄河断流227天;1998年发生长江、嫩江流域特大水灾;2000年发生严重影响中国首都北京及韩国、日本的12次沙尘暴;2004年,淮河流域再次发生严重污染事件。综合分析表明,土地利用/覆盖格局的巨大变化、城市化过程的加速、乡镇企业的迅猛发展成为其主因。一些案例研究表明,重建生态环境安全条件下的中国土地利用/覆盖格局,制定与生态环境安全水平友好的国家土地利用政策,不仅有利于改善中国生态环境安全水平,还将促进其可持续发展,并有益于亚洲及世界生态环境的改良。  相似文献   

区域创新政策评价的框架、测度与检验     

俞立平 《地理科学》2020,40(10):1610-1617

构建区域创新政策评价的理论框架,在宏观知识生产函数中引入信息化作为创新技术进步的替代变量,基于DEA与Malmquist指数,用全要素生产率指数存量来衡量区域创新政策。并以省际高技术产业为例进行了实证,研究结果表明：区域创新政策的特征和评价维度决定评价的多样性,基于政策效果与政策交互作用的区域创新政策评价具有重要意义;区域创新政策总体上处于稳步提高阶段,较低地区以西部中部地区为主;区域创新政策测度模型系统性较好,其检验方法有待进一步深化;采用政府研发经费投入作为区域创新政策的替代变量值得商榷。  相似文献
