The need for environmental and urban planning reached a critical point in the year 2007, when one-half of the world's population
could be defined as living in cities. Urbanisation in India is also increasing at a fast rate. Urban chaos in India, emanating
from the continuous ignorance of fragile ecosystems, calls for the reshaping of existing cities as ‘eco-cities’. The ‘eco-city’—a
well-known concept in the western world—is new to the Indian context. While western connotations of eco-cities should not
be discarded outright in the context of India, core concerns vary significantly for obvious reasons. Recognising two facts—firstly,
eco-city development is altogether a fresh approach to human settlement development in India, and, secondly, the manifold
increase in the vulnerability of cities—this paper discusses documented good practice, reinforcing evolution towards the eco-city
vision. Lessons drawn from the examples cited are further deconstructed in the light of their contribution to urban risk reduction,
which provides direction to appreciating the ‘disaster-resilient eco-community’ concept in Puri, a coastal city in India.
Further, this paper attempts to unravel existing community-based practices in Puri, which are boon to the local environment
and invariably reduce disaster risk. These seemingly modest neighbourhood initiatives symbolise immense societal wealth, which
can be calibrated appropriately for reducing urban environmental risk as well. This paper also illustrates how a ‘disaster
resilient eco-community’ approach is inevitable in the present and future contexts not only to preserve sustainable development
gains but also to secure human well-being. 相似文献

水是城市发展的基础性自然资源和战略性经济资源,而水环境则是生态城建设所依托的生态基础设施之一。为了更合理地解决城市水资源的资源性短缺和利用性短缺等问题,以中新天津生态城水资源节约利用为例,在对天津中新生态城水环境现状和水环境系统进行分析的基础上,从再生水利用、雨水收集、海水淡化等方面入手,结合景观绿地及其灌溉系统、生态城各项规划导则以及梯度水价等管理措施探索性地研究了生态城节水的各项措施,为其他城市的水资源节约利用提供借鉴。 相似文献

中新天津生态城植物多样性分析 总被引:1,自引:0,他引:1

2008年对中新天津生态城规划区域植被进行调查,发现该区域以盐生植被为主,现存植被可分为4个类型15种植物群落;植物区系成分含38科101属135种。本区植被的分布受土壤盐碱度的制约,并受当代人为因素的严重影响,盐生植物资源丰富,其中26种耐盐植物具有较大开发利用价值。因此,建议采取保留与保护现存的盐生植被;利用耐盐植物进行盐碱地绿化及研究和发展本区盐碱地环境的生态管理。 相似文献
