Carrying-capacity as a basis for sustainable development a case study of National Capital Region in India

Sustainable urban development: A review on urban carrying capacity assessment

“…(Wang, 2013). It is widely recognized that this is a limit scale for urban development and indefinite development of the urban area is impossible (Khanna, Ram Babu, & Suju George, 1999;Onishi, 1994). It is expected that population growth could not continue without a degradation in the environment, quality and lifestyle of human living (Summers, 2004).…”

“…With the advancement of technology, some studies have attempted to use computer simulation, remote sensing (RS) or geographical information systems (GIS) to assess the population carrying capability in a specified locality, e.g. (Khanna et al, 1999;Oh et al, 2005;Shi et al, 2013). Compared with the conventional evaluation indicator system, these spatial analysis models are superior in terms of "scientificity, intuition and management" (Shi et al, 2013: 28).…”

Evaluation of carrying capacity and territorial environmental sustainability

“…The carrying capacity is a concept rooted in demography as applied to ecology and biology (Clarke, 2002), and was introduced by Odum (1988) as the number of individuals that can be sustained indefinitely in a given habitat without causing damage to the productivity of ecosystem on which their livelihoods depend. This concept has been extended to the environmental sector and it has been defined as the maximum consumption of natural resources and waste discharge that can be supported in an area without compromising the ecosystem status (Khanna et al, 1999;Oh et al, 2005).…”

“…Most of the existing methodologies for determining the environmental carrying capacity of a territory are based on estimated flows of resources (water, energy, land) and waste (emissions, solid waste, wastewater) that affect the environmental status (Wackernagel and Rees, 1996;Tang and Ye, 1998;Khanna et al, 1999;Yu and Mao, 2002;Clarke, 2002;Komatsu et al, 2005;Oh et al, 2005;Graymore et al, 2010;Yin et al, 2010;Liu and Borthwick, 2011). These flows are defined as critical flows or sustainability thresholds and can be estimated through complex operations based on policy environmental standards and the capacity of ecosystems to provide resources and assimilate the wastes (Kang and Xu, 2010;Dal Sasso, 2001).…”

Regional carrying capacity evaluation and prediction based on GIS in the Yangtze River Delta, China

“…Concept of regional carrying capacity Originally, carrying capacity is defined, for biological species, as the maximum population of the species that is able to sustain in a long term, in a given habitat with limited food, light, water, and other necessities, without impairing its productivity (Khanna et al 1999, Yue et al 2008. RCC, according to Yu (2000) and Yu and Mao (2002), is defined as the magnitude of human population and their socio-economical activities that can be supported by the limited resources without deteriorating the ecological environment in a predictable time span, within a confined region.…”
