Several multivariate statistical methods were comprehensively used to interpret the temporal, spatial patterns and source identification of surface water pollution in Bohai Bay with the large and complex data. Twelve variables water quality indices were surveyed at 12 sites three times a year (May, August, and October) from 1995 to 2005. Cluster analysis (CA) grouped the eleven years into two clusters, Cluster A (1995 to 2001 except 1998) and cluster B (2002 to 2005 and 1998), and spatial CA divided the entire area into three groups. The results of discriminant analysis showed that the temporal CA and spatial CA were effective with 90% and 83.3% correct assignments, respectively. In cluster A, the pollution sources mainly were nutrient factor from non-point source and Hg pollution, oil and organic pollutions were relatively light. In Cluster B, the organic pollution became the mainly pollution source, and the nutrient pollution was still serious problem. In the results of spatial analysis, the group 1 was mainly affected by anthropogenic pollution, the group 3 was seriously affected by oil spill pollution and nutrients pollution, and the group 2 reflected relatively strong water self-purification ability.

Describes how pollution control spending around the world is set to increase from $70 billion (1979) to $115 billion in 1990 in real terms. Expands on the theory that cleaning up ‐ or preventing mistakes ‐ in the environment makes for financial and healthwise good sense. Posits that cleaner air leads to fewer respiratory problems and cleaner water in most areas of manufacturing results in lower fuel use. Focuses on trade, end use competitive modes and marketing patterns regarding water pollution control equipment (WPCE). States that WPCE shipments world wide are projected to rise from $3.3 billion in 1979 to $5.4 billion in 1990, and that this is a dynamic market worthy of investigation. Reports on the methodology, international trade, types of equipment structure and competition and expresses these with the aid of explicit tables. Finishes by estimating size of national, regional and global markets but acknowledges that there are gaps. Concludes that competition is keen but strong market opportunities remain for procedures around the globe in upcoming years.

A systems perspective of waste management allows an integrated approach not only to the five basic functional elements of waste management itself (generation, reduction, collection, recycling, disposal), but to the problems arising at the interfaces with the management of energy, nature conservation, environmental protection, economic factors like unemployment and productivity, etc. This monograph separately describes present practices and the problems to be solved in each of the functional areas of waste management and at the important interfaces. Strategies for more efficient control are then proposed from a systems perspective. Systematic and objective means of solving problems become possible leading to optimal management and a positive contribution to economic development, not least through resource conservation. India is the particular context within which waste generation and management are discussed. In considering waste disposal techniques, special attention is given to sewage and radioactive wastes.

The purpose of this paper is to analyze the impact of the off-office audit of natural resource assets on the prevention and control of water pollution against a background of big data using a differences-in-differences model.

This study constructs a differences-in-differences model to evaluate the policy effects of off-office audit based on panel data from 11 cities in Anhui Province, China, from 2011 to 2017, and analyzes the dynamic effect of the audit and intermediary effect of industrial structure.

The implementation of the audit system can effectively reduce water pollution. Dynamic effect analysis showed that the audit policy can not only improve the quality of water resources but can also have a cumulative effect over time. That is, the prevention and control effect on water pollution is getting stronger and stronger. The results of the robustness test verified the effectiveness of water pollution prevention and control. However, the results of the influence mechanism analysis showed that the mediating effect of the industrial structure was not obvious in the short term.

These findings shed light on the effect of the off-office audit of natural resource assets on the prevention and control of water pollution, and provide a theoretical basis for the formulation of relevant environmental policies. Furthermore, these findings show that the implementation of the audit system can effectively reduce water pollution, which has practical significance for the sustainable development of China's economy against the background of big data.

This study quantitatively analyzes the policy effect of off-office auditing from the perspective of water resources based on a big data background, which differs from the existing research that mainly focuses on basic theoretical analysis.

This chapter studies the link between urban planning and health. Access to safe drinking water is already a very serious issue for large urban populations in fast-growing economies such as India. Water availability is further being impacted by climate change, leading to the drastically increased spread of water-related diseases.

Leh Town, which is located in an ecologically vulnerable semi-arid region of the Himalayas in Ladakh, has been considered for this study because it is undergoing large-scale transformation due to rapid growth in its tourism industry. In 2012–2013 our interdisciplinary group comprising researchers from Germany and India conducted field surveys, including geographic information system-based (GIS) mapping of point sources of water pollution, questionnaire surveys of 200 households and 70 hotels and guesthouses and semi-structured interviews. We also reviewed secondary medical data.

We found that diarrhoeal incidence has increased in the local population in Leh in the past decade, which may be linked to water pollution: Further, we found that rapidly increasing water consumption coupled with a lack of adequate water and sanitation infrastructure is causing serious water pollution.

Further, data is needed for causal connections between water pollution and health impacts to be conclusively drawn.

This study discusses the use of GIS to support a call for the need for more integrated urban planning and decision-making that holistically addresses water and health challenges in Leh and advocates the development of a decentralized or hybrid sanitation system to support water resources conservation as a central dimension of an integrated health management approach.

GIS is also a very useful platform for supporting participatory urban planning in Leh.

With such an integrated urban planning approach, Leh would be a lighthouse example for other towns in the region.

Non-point source pollution risk assessment for surface drinking water catchments is an important basis and premise for the scientific management over water environment, while remote sensing technology may timely find the spatial distribution pattern and variation of risk. Coupling the Non-point source model and remote sensing data is a potential method for the water environment risk assessment. The dual Non-point source model independently developed by China is chosen to study its practical applicability in the experimental catchment area of Hebei Yuecheng Reservoir in combination with the remote sensing and GIS data, and to study the spatial distribution pattern of the Non-point source Phosphorus (P) pollution generated by the spatial landuse. The result shows that:(1) the coupled model is well adapted to the catchment area of Hebei Yuecheng Reservoir, and the simulated Non-point source P load is strongly related to the observation data of the hydrologic stations such as Liujiazhuang, Guantai and etc.; (2) The disorderly development of social economy is the main cause of Non-point source pollution, and the farmlands, urban and rural residential areas in the catchment area are the major risk sources of Non-point source pollution; (3) the two assessment units, catchment unit and administration unit, are employed in this study. They are complementary to each other, which is convenient for management because they can reflect not only the P risk distribution but also the specific location of the administration areas within the risk area.

Recent years have produced significant demand for geographical contributions to the study of social movements in general and of environmental social movement organizations (ESMOs) in particular. Geographical approaches to the study of ESMOs emphasize “the mediation of social movement agency by place” (Miller, 2000; Routledge, 1993) and call attention to the role of place-based environmental knowledge (EK) in the broader “struggle(s) over meaning” that increasingly constitute environmental politics (Buechler, 1997; Escobar, 1992; Rangan, 2000; Watts, 1990). My chapter responds to this call by providing an examination of the reproduction of EK by antipollution organizations in India’s central Ganges River Basin (GRB). Through interviews with organization leaders and members, along with analysis of organizational websites and publications, I examine the EK of two key antipollution organizations in the GRB: The Sankat Mochan Foundation (SMF) and Kanpur Eco-Friends (KEF). Analysis focuses on methods of knowledge reproduction employed by each organization, their respective framing practices, and the localized natures of the EK they reproduce. I argue that each organization works to reproduce a specific and place-based understanding of pollution in the GRB that informs their framing of the pollution problem, the tactical activities in which their members engage, and the power relations that exist between the two organizations and their leaders. Further, I argue that engaging with EK as both a method of understanding pollution and a tactic for consolidating political power is essential to making sense of the relative success of these movement organizations and the challenges they face in trying to build a broader coalition and mass-mobilization against pollution in the Ganges.

We are growing accustomed to shock tactics of the US Administration in dealing with toxic residues in food or additives which are a hazard to man, as well as the daily press infusing sensation, even melodrama, into them, but the recent action of the FDA in calling in from the food market several million cans of tuna and other deep sea fish because of the presence of mercury has had the worthwhile effect of drawing world attention to the growing menace of environmental pollution. The level of mercury in the fish is immaterial; it should never have been there at all, but it stresses the importance of the food chain in the danger to man and animal life generally, including fish beneath the sea. Without underestimating risks of pollution in the atmosphere from nuclear fission products, from particulate matter carried in the air by inhalation or even skin absorption, food and drink, which includes aqua naturale would seem to be the greatest danger to life. What these recent events illustrate in a dramatic manner, however, is the extent of pollution.
