Conclusions Glossary Bibliography Biographical Sketch Summary During Earth's history, species extinction has probably been caused by modifications of the physical environment after impacts such as meteorites or volcanic activity. On the contrary, the actual extinction of species is mainly a result of human activities, namely any form of land use that causes the conversion of vast areas to settlement, agriculture, and forestry, resulting in habitat destruction, degradation, and fragmentation, which are among the most important causes of species decline and extinction. The loss of biodiversity is unique among the major anthropogenic changes because it is irreversible. The importance of preserving biodiversity has increased in recent times. The global recognition of the alarming loss of biodiversity and the acceptance of its value resultedUNESCO in the Convention on Biologi – calEOLSS Diversity. In addition, in Europe, the challenge is also the implementation of the European strategy for biodiversity conservation and agricultural policies, though it is increasingly recognized that the strategy is limitedSAMPLE by a lack of basic ecological CHAPTERS information and indicators available to decision makers and end users. We have reached a point where we can save biodiversity only by saving the biosphere. -

Water Supply and Sanitation & Integrated Water Resources
Water Supply and Sanitation & Integrated Water Resources Management: why seek better integration? John Butterworth1 and John Soussan2 1Natural Resources Institute, University of Greenwich, UK 2Centre for Water Policy and Development, University of Leeds, UK WHIRL Project Working Paper 2 Preliminary results of research for discussion and comment Prepared for WHIRL project workshop on ‘Water Supply & Sanitation and Watershed Development: positive and negative interactions’, Andhra Pradesh, India, 5-14 May 2001 This project is supported by the UK Department for International Development (DFID) through the Infrastructure and Urban Development Division’s Knowledge and Research programme. Project R7804 ‘Integrating drinking water needs in watershed projects’ 1 INTRODUCTION This working paper was prepared as a contribution to a joint Indian, South African and UK research project on Water, Households and Rural Livelihoods (WHIRL). The objectives of the paper are to identify approaches to improve access of the poor to secure, safe and sustainable water supplies in areas of water scarcity, and to identify some of the key challenges to the more effective management of water resources in these areas. It is targeted at organisations responsible for the delivery of water supply and sanitation (WSS) services and management of land and water resources in developing countries. It aims to promote discussion and dialogue between the research partners and these organisations. The paper is produced at a time of major changes to approaches to the management of water resources in general and the delivery of WSS services in particular, throughout the developing world. The limitations of traditional approaches based on supply provision have been recognised in many places, and the principles of integrated water resources management developed (IWRM). -

Environmental Systems the Atmosphere and Hydrosphere
Environmental Systems The atmosphere and hydrosphere THE ATMOSPHERE The atmosphere, the gaseous layer that surrounds the earth, formed over four billion years ago. During the evolution of the solid earth, volcanic eruptions released gases into the developing atmosphere. Assuming the outgassing was similar to that of modern volcanoes, the gases released included: water vapor (H2O), carbon monoxide (CO), carbon dioxide (CO2), hydrochloric acid (HCl), methane (CH4), ammonia (NH3), nitrogen (N2) and sulfur gases. The atmosphere was reducing because there was no free oxygen. Most of the hydrogen and helium that outgassed would have eventually escaped into outer space due to the inability of the earth's gravity to hold on to their small masses. There may have also been significant contributions of volatiles from the massive meteoritic bombardments known to have occurred early in the earth's history. Water vapor in the atmosphere condensed and rained down, of radiant energy in the atmosphere. The sun's radiation spans the eventually forming lakes and oceans. The oceans provided homes infrared, visible and ultraviolet light regions, while the earth's for the earliest organisms which were probably similar to radiation is mostly infrared. cyanobacteria. Oxygen was released into the atmosphere by these early organisms, and carbon became sequestered in sedimentary The vertical temperature profile of the atmosphere is variable and rocks. This led to our current oxidizing atmosphere, which is mostly depends upon the types of radiation that affect each atmospheric comprised of nitrogen (roughly 71 percent) and oxygen (roughly 28 layer. This, in turn, depends upon the chemical composition of that percent). -

Paani Foundation Is a Not-For-Profit Organization Which Has Been the Brainchild of Aamir Khan and Kiran Rao
ANNUAL REPORT PAANI FOUNDATION’S ACTIVITIES IN 2016 Background: Paani Foundation is a not-for-profit organization which has been the brainchild of Aamir Khan and Kiran Rao. The organization was registered in early 2016 in order to work towards creating a drought-free Maharashtra. The idea originated from the television show Satyameva Jayate which was being anchored by Aamir Khan , addressing various social issues . One of the crucial issues that strongly came up was the water scarcity in Maharashtra which was mainly due to the topographical pattern of large areas in existence which are drought prone and face serious lack of rain every year. India is classified globally as a water-adequate nation. It has neither abundance nor scarcity. It has enough for its needs. Yet, increasingly, more and more people do not have water to drink, more and more farmers face drought and starvation, and more and more industries shut down or cannot grow because of a shortage of water. The reason for the Water Crisis: The crisis is largely man-made and has four key causes: 1. Pollution: We have polluted our lakes and rivers. 2. Over-Exploitation: We have recklessly pumped out ground water without bothering to recharge the groundwater table resulting in a catastrophic fall in its level. 3. Irrational Water Management: Can be described well with the example of highly water-intensive sugarcane cultivation in drought-prone areas. 4. Climate Change: Rainfall is getting compressed in both space and time. The number of rain days is decreasing. Rainfall is concentrated in small areas with vast land masses subject to drought. -
Using the Water Quality Index (WQI), and the Synthetic Pollution Index
Sains Malaysiana 49(10)(2020): 2383-2401 http://dx.doi.org/10.17576/jsm-2020-4910-05 Using the Water Quality Index (WQI), and the Synthetic Pollution Index (SPI) to Evaluate the Groundwater Quality for Drinking Purpose in Hailun, China (Penggunaan Indeks Kualiti Air (WQI) dan Indeks Pencemaran Sintetik (SPI) untuk Menilai Kualiti Air Bawah Tanah untuk Tujuan Minuman di Hailun, China) TIAN HUI*, DU JIZHONG, SUN QIFA, LIU QIANG, KANG ZHUANG & JIN HONGTAO ABSTRACT Due to the impact of human agricultural production, climate and environmental changes. The applicability of groundwater for drinking purposes has attracted widespread attention. In order to quantify the hydrochemical characteristics of groundwater in Hailun and evaluate its suitability for assessing water for drinking purposes, 77 shallow groundwater samples and 57 deep groundwater samples were collected and analyzed. The results show that deep groundwater in - aquifers in the study area is weakly alkaline, while that in shallow is acidic. The abundance is in the order HCO3 > - 2- 2+ + 2+ Cl > SO4 for anions, and Ca > Na > Mg for cations. Groundwater chemical type were dominated by HCO3-Ca, HCO3-Ca• Mg, and HCO3-Ca• Na. Correlation analysis (CA) and Durov diagram showed that rock weathering and dissolution, human activities, and the hydraulic connection between shallow and deep water are the main reasons affecting the chemical composition of water in Helen. The analysis of water samples based on the WQI model showed that about 23.37, 23.37, 32.46, 12.98, and 7.79% of the shallow groundwater samples were excellent, good, poor, very poor, and unsuitable for drinking purposes, respectively, and that 61.40, 30.90, 5.26, 1.75, and 1.75% of the deep groundwater samples were excellent, good, poor, very poor, and unsuitable for drinking purposes, respectively. -

Controlling Groundwater Pollution from Petroleum Products Leaks
Environmental Toxicology III 91 Controlling groundwater pollution from petroleum products leaks M. S. Al-Suwaiyan Civil Engineering Department, King Fahd University of Petroleum and Minerals, Saudi Arabia Abstract Groundwater is the main source of potable water in many communities. This source is susceptible to pollution by toxic organic compounds resulting from the accidental release of petroleum products. A petroleum product like gasoline is a mixture of many organic compounds that are toxic at different degrees to humans. These various compounds have different characteristics that influence the spread and distribution of plumes of the various dissolved toxins. A compositional model utilizing properties of organics and soil was developed and used to study the concentration of benzene, toluene and xylene (BTX) in leachate from a hypothetical site contaminated by BTX. Modeling indicated the high and variable concentration of contaminants in leachate and its action as a continuous source of groundwater pollution. In a recent study, the status of underground fuel storage tanks in eastern Saudi Arabia and the potential for petroleum leaks was evaluated indicating the high potential for aquifer pollution. As a result of such discussion, it is concluded that more effort should be directed to promote leak prevention through developing proper design regulations and installation guidelines for new and existing service stations. Keywords: groundwater pollution, petroleum products, dissolved contaminants, modelling contaminant transport. 1 Introduction Water covers about 73% of our planet with a huge volume of 1.4 billion cubic kilometers most of which is saline. According to the water encyclopedia [1], only about 3-4% of the total water is fresh. -
Groundwater Overdraft, Electricity, and Wrong Incentives : Evidence from Mexico
Groundwater Overdraft, Electricity, and Wrong Incentives : Evidence from Mexico Vincente Ruiz WP 2016.05 Suggested citation: V. Ruiz (2016). Groundwater Overdraft, Electricity, and Wrong Incentives : Evidence from Mexico. FAERE Working Paper, 2016.05. ISSN number: 2274-5556 www.faere.fr Groundwater Overdraft, Electricity, and Wrong Incentives: Evidence from Mexico by Vicente Ruiz⇤ Last version: January 2016 Abstract Groundwater overdraft is threatening the sustainability of an increasing number of aquifers in Mexico. The excessive amount of groundwater ex- tracted by irrigation farming has significantly contributed to this problem. The objective of this paper is to analyse the effect of changes in ground- water price over the allocation of different production inputs. I model the technology of producers facing groundwater overdraft through a Translog cost function and using a combination of multiple micro-data sources. My results show that groundwater demand is inelastic, -0.54. Moreover, these results also show that both labour and fertiliser can act as substitutes for groundwater, further reacting to changes in groundwater price.
