Abstract

Environmental or ‘ecological’ footprints have been widely used as partial indicators of sustainability; specifically of resource consumption and waste absorption transformed in terms of the biologically productive land area required by a population. The environmental footprint of the Unitary Authority of Bath & North East Somerset (BANES) in the South West of England (UK) has been estimated in terms of global hectares (gha) required per capita. BANES has a population of about 184,870 and covers an area of 35,200 hectares, of which two-thirds is on ‘green belt’ land. The UNESCO World Heritage City of Bath is the principal settlement, but there are also a number of smaller urban communities scattered amongst its surrounding area (‘hinterland’ or ‘bioregion’). The overall footprint for BANES was estimated to be 3.77 gha per capita (gha/cap), which is well above its biocapacity of 0.67 gha/cap and ‘Earthshare’ of 1.80 gha per capita. Direct Energy use was found to exhibit the largest footprint component (a 31% share), followed by Materials & Waste (30%), Food & Drink (25%), Transport (10%) and Built Land (4%), whereas the Water footprint was negligibly small (∼0%) by comparison. Such data provides a baseline for assessing their planning strategies for future development.
城市社区及其周边生物区的环境足迹分析
环境或“生态”足迹已被广泛用作可持续性的部分指标;特别是资源消耗和废物吸收转化为人口所需的生物生产性土地面积。英国西南部巴斯和东北萨默塞特联合政府(BANES)的环境足迹以人均所需的全球公顷(gha)来估算。贝恩斯的人口约为184,870人,占地面积35,200公顷,其中三分之二位于“绿化带”上。联合国教科文组织世界遗产城市巴斯是主要的定居点,但也有一些较小的城市社区分散在其周边地区(“腹地”或“生物区”)。据估计,BANES的总足迹为人均3.77 gha (gha/cap),远高于其0.67 gha/cap的生物承载力和人均1.80 gha的“地球份额”。发现直接能源使用表现出最大的足迹组成部分(31%的份额),其次是材料和废物(30%),食品和饮料(25%),运输(10%)和建设土地(4%),而相比之下,水足迹微不足道(约0%)。这些数据为评估它们未来发展的规划战略提供了基线。
