Abstract

Rapid urbanization in cities is crafting major environmental problems, leading to degradation of urban ecosystems and is responsible for creating an imbalance between demand and supply of resources. Ecological Footprint Analysis (EFA) is a tool that can be used to assess this imbalance scientifically and determine the sustainability of a particular area. Our study aims to determine the urban sustainability of Kangra district in Himachal Pradesh, a hilly state in North Western Himalayas, India situated in North western Himalayas by using one of the Ecological Footprint Analysis (EFA) components, the built-up land footprint, as a pragmatic tool for analysis and planning of the urban region. The total built-up land footprint, total biocapacity and total ecological deficit are 18146.095 g ha,15968.564 g ha and 2177.531 g ha respectively whereas built-up land footprint per capita, built-up land biocapacity per capita and ecological deficit per capita are 1.371 g ha, 1.206 g ha, and 0.164 g ha respectively in different urban areas. Consequently, it is concluded that the built-up land results in an ecological deficit, and the system is considered unsustainable because its ecological footprint exceeds its bio capacity. It is suggested that urban sustainability should move and work on ecological principles so that the vision encompassing global goals and agenda 2030 for sustainable development can be achieved.
利用喜马拉雅山西北部城市生态系统的生态足迹评估环境可持续性
城市的快速城市化带来了严重的环境问题,导致城市生态系统退化,并造成资源供需失衡。生态足迹分析 (EFA) 是一种可用于科学评估这种不平衡并确定特定地区可持续性的工具。喜马偕尔邦是印度喜马拉雅山脉西北部的一个丘陵邦,我们的研究旨在利用生态足迹分析(EFA)的组成部分之一--已建土地足迹,作为分析和规划城市区域的实用工具,确定该邦康格拉地区的城市可持续性。不同城市地区的建成区土地总足迹、总生物容量和总生态赤字分别为 18146.095 克公顷、15968.564 克公顷和 2177.531 克公顷,而人均建成区土地足迹、人均建成区土地生物容量和人均生态赤字分别为 1.371 克公顷、1.206 克公顷和 0.164 克公顷。因此,得出的结论是,建成区造成了生态赤字,该系统被认为是不可持续的,因为其生态足迹超过了其生物容量。研究建议,城市可持续发展应遵循生态原则,以实现可持续发展的全球目标和 2030 年议程。
