Oxygen is a product of photosynthesis and is essential for human survival. It also has a profound effect on ecosystems as the atmospheric oxygen balance is the basis for regional ecological sustainability. The Pearl River Delta (PRD) has experienced rapid urbanization and has become one of China’s three major urban agglomerations. This study focused on the oxygen balance of the PRD in 2011, and...

ABSTRACT- Sustainability and environmental management are the most cited ideas linking the environment and development. The sustainability of natural resources depends upon our paradigm and related approaches to the relationship between society and the environment. Efficient management is a primary task due to the pressure on nature. Ecological footprint analysis has been intro...

Human use of freshwater resources has altered the dynamics of hydrologic regimes in rivers around the world. Frequency, timing, and periodicity of extreme fluctuations in water flow have been modified, disrupting the flow regimes to which lotic biota have adapted over evolutionary time. The goal of the proposed research is to increase our understanding of how the hydrologic regime modulates lin...

  Specific leaf area ( the ratio of leaf area to dry mass) is one of the most important ecological variables can be viewed as the tradeoff between ecosystem mass balance and ecosystem energy balance. This variable is further particularly sensitive to changes in the external environment and in the internal functioning of the plant. In this research, we studied the effect of species and leaf posi...

In this study, an inexact stochastic fuzzy programming (ISFP) model is proposed for land-use allocation (LUA) and environmental/ecological planning at a watershed level, where uncertainties associated with land-use parameters, benefit functions, and environmental/ecological requirements are described as discrete intervals, probabilities and fuzzy sets. In this model, an interval stochastic fuzz...

The application of the latest digital technologies changes the ways of thinking of entrepreneurial behaviour and motivation of decision-making, principles of organization of their functioning, so the purpose of work is to form a model of achieving a balanced balance between economic efficiency and environmental and social responsibility of the digitized enterprise, determining the scientific ba...

The paper explores the development of ecological sanitation (EcoSan) within the small-town context of Lichinga, Niassa Province, Mozambique. The paper looks at how ESTAMOS (a Mozambican NGO) and WaterAid introduced EcoSan in Lichinga, how families and communities have responded to EcoSan, and key lessons learned during the process to date that could be relevant to others within and beyond Mozam...

When comparing the average citation impact of research groups, universities and countries, field normalisation reduces the influence of discipline and time. Confidence intervals for these indicators can help with attempts to infer whether differences between sets of publications are due to chance factors. Although both bootstrapping and formulae have been proposed for these, their accuracy is u...

The intention of this paper is to propose interaction design as a venue for IS research into sustainability and in that connection also propose a new theoretical psychological approach to interaction design. This new theoretical psychological framework is based on ecological psychology and activity theory. The paper will outline the scientific demands for the framework as well as the frameworks...
