Urbanization is rapidly emerging as one of the most potent forces to shape the global environment. There is already immense pressure on urban natural capital; local biodiversity has been isolated and overshadowed by urban sprawl. The irreversible loss of native biodiversity has an impact on multi-scale ecosystem functioning. It has become critical to reconcile these issues to ensure that urban development is sustainable and, in fact, betters the quality of life. This essay explores the interactions between urban biodiversity, natural capital, and people in urban human ecosystems. A strong scientifi c basis through continual mapping, monitoring, and assessment is required to communicate the implicit connection between biodiversity and the quality of life to the public and policymakers. Grassroots innovation, public participation, and local governance are critical to maintaining urban biodiversity. A natural capital and ecosystem approach are strongly recommended to ensure that urbanization becomes more sustainable and cities are able to reduce their ecological footprint.
城市化正迅速成为塑造全球环境的最有力力量之一。城市自然资本已经面临巨大压力;由于城市的扩张,当地的生物多样性被孤立和遮蔽。本土生物多样性不可逆转的丧失对多尺度生态系统功能产生了影响。调和这些问题,以确保城市发展是可持续的,实际上是提高生活质量,已变得至关重要。本文探讨了城市人类生态系统中城市生物多样性、自然资本和人之间的相互作用。为了向公众和政策制定者传达生物多样性与生活质量之间的隐含联系,需要通过持续的制图、监测和评估提供强有力的科学依据。基层创新、公众参与和地方治理对维持城市生物多样性至关重要。强烈建议采用自然资本和生态系统方法,以确保城市化更具可持续性,城市能够减少其生态足迹。

Triggered by the unprecedented loss of biodiversity, the Parties to the Convention on Biological Diversity adopted the 2010 biodiversity target, that is, “to achieve, by 2010, a signifi cant reduction of the current rate of biodiversity loss at the global, regional, and national level, as a contribution to poverty alleviation and to the benefi t of all life on Earth”. This target is now being revised as a post-2010 target. Whatever the target may, be- 2010 or beyond, the challenge step is to put mechanisms in place to track progress towards the targets. There is a large body of trend indicators as well as response indicators for assessing progress towards the target. In this paper, based on a conceptual framework and available information, we reviewed the existing scenario on the biodiversity targets, which resulted in a set of criteria and a set of policy-relevant research questions to be further developed as policy-response indicators for assessing progress that the countries are making towards achieving the biodiversity targets. The criteria and research questions are grouped under four policy areas: implementation mechanism of global biodiversity conventions at the national level; integration of biodiversity into policies and programs of other sectors; public awareness and support, and availability of resources to work towards the targets. These indicators need to be measured at national level and monitored globally.
在生物多样性空前丧失的推动下,《生物多样性公约》缔约方通过了2010年生物多样性目标,即“到2010年,在全球、区域和国家各级显著降低目前生物多样性丧失的速度,为减轻贫困和造福地球上所有生命做出贡献”。目前正在将这一目标修订为2010年后的目标。无论目标是什么,在2010年或以后,挑战的一步是建立机制来跟踪实现目标的进展。有大量的趋势指标和反应指标用于评估实现目标的进展情况。本文基于概念框架和现有信息,回顾了生物多样性目标的现有情景,得出了一套标准和一套与政策相关的研究问题,作为评估各国实现生物多样性目标进展的政策响应指标。标准和研究问题分为四个政策领域:国家层面的全球生物多样性公约实施机制;将生物多样性纳入其他部门的政策和方案;公众的认识和支持,以及为实现这些目标而努力的资源。这些指标需要在国家一级加以衡量,并在全球范围内加以监测。

Biodiversity management for sustainable development of cities 生物多样性管理促进城市可持续发展
Pub Date : 2010-01-01 DOI: 10.3233/RED-120069
N. Khera
For sustainability of urban areas, urban ecosystem management must integrate biodiversity conservation in the planning process. While it is an established practice to set aside areas for conservation, it is also critical to continuously monitor urban areas using suitable indicators. The need for monitoring environmental changes at local levels assumes greater signifi cance in light of the predicted impacts of climate change on ecosystems and biodiversity. Birds serve as useful indicators for monitoring biodiversity at the ecosystem-community level. The impacts of global climate change on bird populations can be observed and monitored. This paper focuses on the urban area of Delhi, based on previous studies and work during 2008-09. Between 2006 and 2008, there occurred a general decline in the abundance and frequency of bird species, except for the common myna, house crow, and rock pigeon. The most striking feature is the change in relative density of occurrence of the rock pigeon. Delhi's vegetation has a predominance of exotic species, with limited shrub and herb cover. The paper proposes to initiate conservation action to maintain urban biodiversity under three levels-within greenspaces, at the landscape level, and at the policy level.
为了城市地区的可持续性,城市生态系统管理必须将生物多样性保护纳入规划过程。虽然设立保护区是一种既定做法,但使用合适的指标持续监测城市地区也至关重要。鉴于气候变化对生态系统和生物多样性的预测影响,在地方一级监测环境变化的必要性具有更大的重要性。鸟类是监测生态系统-群落层面生物多样性的有用指标。全球气候变化对鸟类种群的影响是可以观察和监测的。本文以德里市区为研究对象,基于之前2008-09年的研究和工作。2006 - 2008年间,除了常见的八哥、家鸦和岩鸽外,鸟类种类的丰度和频率普遍下降。最显著的特征是岩鸽相对密度的变化。德里的植被以外来物种为主,灌木和草本植物覆盖有限。本文建议在绿地、景观和政策三个层面启动保护行动,以维持城市生物多样性。

Urbanization in the US: land use trends, impacts on forest area, projections, and policy considerations 美国城市化:土地利用趋势、对森林面积的影响、预测和政策考虑
Pub Date : 2010-01-01 DOI: 10.3233/RED-120068

Since World War II, socio-economic drivers of US urbanization such as population totals and personal income levels have increased substantially. Human land use is the primary force driving changes in forest ecosystem attributes including forest area, which is the focus of this paper. The percentage of the US population residing in urban areas is higher than that in India. In the last few decades, the primary reason behind conversion of large areas of US forests is for urban and development uses. Since 1990, land use changes in the US that have affected forests have been heavily concentrated in the South. Nationwide, more than 60% of US housing units built during the 1990s were constructed on or near areas of wildland vegetation. Between 1982 and 1997, the US population grew by 17%, while the urbanized area rose by 47%. The amount of land area per additional individual dedicated to new housing has almost doubled in the last 20 years. About 18 million hectares of private forest are projected to experience housing density increases by 2030, with the most heavily impacted watersheds occurring in the East. The US population is projected to grow by more than 120 million (40%) by 2050. Deforestation associated with this growth is projected to exceed 20 million hectares (13% of the existing private forest area). Fragmentation of remaining forests is also projected, and is expected to be concentrated in distinct sub-regions, namely, the US South, that include urbanizing areas and areas close to interstate highway corridors.
自第二次世界大战以来,美国城市化的社会经济驱动因素,如人口总数和个人收入水平大幅提高。人类土地利用是包括森林面积在内的森林生态系统属性变化的主要驱动力,这是本文研究的重点。美国居住在城市地区的人口比例高于印度。在过去的几十年里,美国大片森林被转化为城市和发展用途的主要原因。自1990年以来,美国影响森林的土地利用变化主要集中在南部。在全国范围内,20世纪90年代建造的美国住房中,超过60%建在荒地植被上或附近。1982年至1997年间,美国人口增长了17%,而城市化面积增长了47%。在过去的20年里,每增加一个人用于新建住房的土地面积几乎翻了一番。预计到2030年,约有1800万公顷的私人森林的住房密度将增加,其中受影响最严重的流域位于东部。到2050年,美国人口预计将增长超过1.2亿(40%)。与这一增长相关的森林砍伐预计将超过2000万公顷(占现有私人森林面积的13%)。还预测了剩余森林的破碎化,预计将集中在不同的分区域,即美国南部,包括城市化地区和靠近州际公路走廊的地区。

Forests, heritage green spaces, and neighbourhood parks: citizen's attitude and perception towards ecosystem services in Bengaluru 森林、传统绿地和社区公园:班加罗尔市民对生态系统服务的态度和看法
Pub Date : 2010-01-01 DOI: 10.3233/RED-120072

Traditionally, conservation has been mainly addressed in relation to large pristine ecosystems such as forests that deliver a wide variety of ecosystem services. This perception of large green patches providing more services seems to be strongly entrenched in the minds of people. So much so, that even though cities comprise mainly of several small neighbourhood parks and a few large heritage parks, the large parks seem to attract the attention and support of naturalists, ecologists, and citizens. The large parks, undoubtedly, provide a wider range of services as compared to small ones. However, small parks also provide services that benefi t the neighbourhood society, which cannot be undervalued. Apart from recreational services, our field surveys show that these small parks are important pockets for migratory birds and other local biodiversity. This study, through social surveys with park users across the city of Bengaluru, attempts to understand people's perception towards a gradient of green spaces—‘forests, heritage parks, and neighbourhood parks’.
传统上,保护主要涉及提供各种生态系统服务的大型原始生态系统,如森林。这种大片绿地提供更多服务的观念似乎在人们的脑海中根深蒂固。因此,尽管城市主要由一些小的社区公园和一些大型的遗产公园组成,但大型公园似乎吸引了博物学家、生态学家和市民的注意和支持。毫无疑问,与小型公园相比,大型公园提供的服务范围更广。然而,小公园也提供有益于社区社会的服务,这一点不容低估。除了提供娱乐服务外,我们的实地调查表明,这些小型公园是候鸟和其他当地生物多样性的重要口袋。本研究通过对班加罗尔市公园使用者的社会调查,试图了解人们对绿色空间梯度的看法——“森林、遗产公园和社区公园”。

An evaluation of alternatives for cooking energy in Nigeria's household energy mix 对尼日利亚家庭能源结构中烹饪能源替代品的评估
Pub Date : 2009-01-01 DOI: 10.3233/RED-120057

Globally, energy consumption is projected to grow, with the major increase expected in developing countries, including Nigeria. Bio-energy sources accounted for 60% of the total final energy consumption in Nigeria, of which 85% was utilized by the household sector, in 2000. The effect of technology intervention on household energy mix in Nigeria was examined for a 30-year period by using four different economic development scenarios. These consist of the baseline scenario, NEEDS (National Economic Empowerment and Development Strategy) Baseline, or N_BS, and three technology intervention scenarios, namely, NEEDS Trend Scenario, or N_TS, NEEDS Action Scenario, or N_AOS, and Non-NEEDS Scenario, or N-NS. The study was carried out for different ecological zones, namely, forest and savanna. Long-range Energy Alternatives Planning, or LEAP, system, an energy simulation model, was employed for the analysis of the study. Lower and upper limits of the cost of technology intervention are $17.40 billion and $39.20 billion for N_BS and N-NS, respectively. The final energy demand dropped by about 47%, 55%, and 64% for the three intervention scenarios, namely, N_TS, N_AOS, and N-NS, respectively. Environmental implications, in terms of GHG (greenhouse gas) savings, are savings of 1.5 billion kg of C equivalent, and the avoided cost is about −$0.11 million/tonne of C equivalent, which actually represents benefit. Cumulative GHG emission per capita at about 690 kg CO2 equivalent was highest for N_BS in 2030, with the least emission occurring for N-NS for the same time period, at 550 kg CO2 equivalent. The final energy intensity for the country's household sector was estimated to be 50.96 GJ/annum. With a technology intervention that is more efficient than the current trend and provides better alternatives for cooking energy, this figure is expected to drop appreciably over the 30-year time frame of the analysis. However, the immediate contending issues for household energy use in Nigeria are ensuring accessibility to energy sources in terms of availability and affordability, and enabling the rural populace and urban poor to achieve a sustainable path for national economic growth and development.
在全球范围内,能源消费预计将增长,预计主要增长将出现在发展中国家,包括尼日利亚。2000年,生物能源占尼日利亚最终能源消费总量的60%,其中85%被家庭部门利用。通过使用四种不同的经济发展情景,研究了技术干预对尼日利亚家庭能源结构的影响,为期30年。这些包括基线情景,需求(国家经济赋权和发展战略)基线,或N_BS,以及三个技术干预情景,即需求趋势情景,或N_TS,需求行动情景,或N_AOS,和非需求情景,或N-NS。本研究针对不同的生态区,即森林和稀树草原进行。采用能源仿真模型LEAP (long - term Energy Alternatives Planning)系统进行分析。N_BS和N-NS的技术干预成本下限和上限分别为174亿美元和392亿美元。在N_TS、N_AOS和N-NS三种干预方案下,最终能源需求分别下降了47%、55%和64%左右。就温室气体节省而言,对环境的影响是节省15亿公斤碳当量,避免的成本约为每吨碳当量- 11万美元,这实际上是一种效益。2030年,N_BS的人均累积温室气体排放量最高,约为690千克二氧化碳当量,同一时期N-NS的人均累积温室气体排放量最少,为550千克二氧化碳当量。该国家庭部门的最终能源强度估计为50.96吉焦/年。随着技术干预比目前的趋势更有效,并提供更好的烹饪能源替代品,预计这一数字将在分析的30年时间框架内明显下降。然而,尼日利亚家庭能源使用的直接竞争问题是确保在可得性和可负担性方面获得能源,并使农村人口和城市穷人能够实现国家经济增长和发展的可持续道路。

Environmental implications, in terms of GHG (greenhouse gas) savings, are savings of 1.5 billion kg of C equivalent, and the avoided cost is about −$0.11 million/tonne of C equivalent, which actually represents benefit. Cumulative GHG emission per capita at about 690 kg CO2 equivalent was highest for N_BS in 2030, with the least emission occurring for N-NS for the same time period, at 550 kg CO2 equivalent. The final energy intensity for the country's household sector was estimated to be 50.96 GJ/annum. With a technology intervention that is more efficient than the current trend and provides better alternatives for cooking energy, this figure is expected to drop appreciably over the 30-year time frame of the analysis. However, the immediate contending issues for household energy use in Nigeria are ensuring accessibility to energy sources in terms of availability and affordability, and enabling the rural populace and urban poor to achieve a sustainable path for national economic growth and development.","PeriodicalId":17166,"journal":{"name":"Journal of Resources, Energy, and Development","volume":"96 1","pages":"23-43"},"PeriodicalIF":0.0,"publicationDate":"2009-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83044770","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The Kyoto Protocol (KP) is a protocol to the United Nations Framework Convention on Climate Change (UNFCCC or FCCC), and primary tool aimed at combating global warming and climate change. The KP does not cover emissions from international bunkers and in its paragraph 2.2 directs Annex I countries to pursue reduction of GHG emissions from marine and aviation bunker fuels by ‘working through’ IMO (International Maritime Organization) and ICAO (International Civil Aviation Organization) respectively. Getting the mandate from UNFCCC, IMO and ICAO have been leading the discussions on formulating a regime to address the GHG (greenhouse gas) emissions from shipping and aviation respectively. However, there are differences on the issue of coverage of emissions from international bunkers (aviation and shipping) and especially the scope of the application of market based measures. Some of the nations want the global application of measures based on the ‘no more favourable treatment principle‘ (which was adopted in 1982 in the Paris memorandum of understanding on port state control and proposes ‘flag neutrality’) in the case of shipping and Chicago Convention in the case of aviation. On the other hand, other nations want the adoption of CBDR (common but differentiated responsibility) principles in any proceeding on the matter. The debate has entered into a deadlock. The paper discusses this issue of the coverage of GHG emissions from international marine and aviation bunkers and brings to light the various discussions that have happened on the same. An attempt has been made to identify the problem associated with the issue and finally some recommendations have been made.
《京都议定书》(KP)是《联合国气候变化框架公约》(UNFCCC或FCCC)的一项议定书,也是应对全球变暖和气候变化的主要工具。《京都议定书》不包括国际燃料油的排放,并在其第2.2段中指示附件一国家分别通过IMO(国际海事组织)和ICAO(国际民用航空组织)努力减少海洋和航空燃料油的温室气体排放。根据《联合国气候变化框架公约》的授权,国际海事组织和国际民航组织一直在牵头讨论制定解决航运和航空温室气体排放问题的机制。但是,在国际燃料(航空和航运)排放的范围问题上,特别是在以市场为基础的措施的适用范围问题上存在分歧。一些国家希望在全球范围内采用基于“不给予更优惠待遇原则”的措施(该原则于1982年在关于港口国控制的巴黎谅解备忘录中被采纳,并提出了“旗帜中立”),适用于航运,适用于航空的芝加哥公约。另一方面,其他国家希望在有关该问题的任何程序中采用CBDR(共同但有区别的责任)原则。辩论陷入了僵局。本文讨论了国际海洋和航空掩体温室气体排放的覆盖问题,并揭示了在同一问题上发生的各种讨论。试图找出与这个问题有关的问题,最后提出了一些建议。
