China is a country frequently hit by floods and droughts. Managing water resources and minimizing the losses caused by water disasters has always been among the most important issues faced by the Chinese government in governing the state. In recent years, to tackle the water problems in China and to meet the requirement of sustainable economic and social development, we have actively pursued sustainable water development. Thinking about water management has thus been greatly modified and remarkable achievements have been made accordingly. The Yellow River, known as the Mother River of China, is the cradle of Chinese civilization, whose problems can represent that of most Chinese rivers. Citing the Yellow River management in recent years as an example, this paper elaborates the strategy of sustainable water development in China.

Abstract. With the rapid economy development and social civilization progress, the Chinese Government also is improving ecological environmental conditions. More efforts have been made to solve water problems through the implementation of stringent water resources management, as a key government policy on water. Thus, monitoring of water resources has been strengthened, being a main component of the hydrological work in recent years. Compared with routine hydrological monitoring, water resources monitoring pays more attention to the quantity and quality variations of regional waters, to reflect the status of water in river basins and administrative regions. In this paper, the overall layout of the hydrometric network in China is presented, monitoring efforts of the natural water cycle and water consumptions are analyzed, methodologies of water resources monitoring, which are commonly applied in the country, are summed up. Taking the hydrometric network planning on interprovincial boundary waterbodies as example, a summary of the planning at interprovincial boundary river sections is presented. The planning can meet the need of water resources management of administrative divisions. It can also improve the overall water resources monitoring for the country.

Water is one of the basic natural resources and a strategic economic one. According to Chinese law (The Constitution and The 2002 Water Law), water resources are national properties and the state government has the responsibility to administer and protect them. At present, water administration is shared by several ministries of the State Council and called “nine dragons administer water”. This paper illustrates the overall water administration scheme. It focuses on the overlapping mandates and interactions between various ministries, particularly those between the Ministry of Water Resources (MWR) and the State Environment Protection Administration (SEPA). The paper then analyzes the reasons why conflicts and disputes over ministry policies and strategies occur and the resultant lowering of administration efficiency and degradation of the water environment. Considering the complexity of water administration and the multiple demands on and limited water resources, some trends must be developed in water administration institutions to improve the efficiency of water administration. In particular, water administration must be strengthened and unified; administrative power must be separated from supervisory power; watershed management and planning must be strengthened; and cooperation among the related water departments must be increased.

Abstract Groundwater is an important water source to support China's economic and social development. Since the 1970s, China, especially the north region, has started to intensively pump groundwater as a water supply for agricultural irrigation, industry and city expansion. To meet the water demand due to the rapid development of the economy and society, groundwater is continuously and disorderly exploited to a great extent for a prolonged time in some regions in China, besides faulty operation and management, and insufficient emphasis on protection, which leads to severe problems of groundwater over-exploitation and contamination. In recent years, the Chinese government has attached great importance to groundwater protection. This paper illustrates the general ideas and strategies of groundwater protection and management in China from the aspects of over-exploitation control, quality protection, water ecosystem protection, and implementation of the strictest water management systems.

Testo completoAbstract (sommario):
In order to achieve a more sustainable mode of development, the government of China declared its intention to build a harmonious socialist society, and the Ministry of Water Resources (MWR) proposed ‘human–water harmony’. However, some problems still exist in China's water resources management (CWRM), which affect management performance and trigger acute water crisis. Nowadays, the human–water relationship in China is disharmonious and the relationship between human activities and water resources has entered into a vicious cycle. This paper concluded that achieving human–water harmony is a necessary and rational pathway to solve China's water problems on the basis of reviewing the development course of CWRM. In order to achieve human–water harmony in China, many impressive efforts both in terms of policies and measures have been made. Ultimately, they pointed out that human–water harmony can be achieved through our tireless efforts as long as people hold the belief that the idea of ‘human–water harmony’ is the first and the foremost way to deal with the contradiction between human activities and water resources.

Despite China’s great stride in technology development and economic recovery, water remains a major issue of concern. Water has a direct impact on agriculture and food production, hence, water management is critical to achieving food security. This paper reviews in a broader perspective the relationship between water resource management and food security in China, and assesses water resource management interms of water use, pollution and influence of government policies, as well as social and economic systems. It also highlights the challenges of water resource management and its implications on agriculture and food security in the Guangxi province of South China. The review also sets a background upon which further studies and frameworks could be developed to help provide a sustainable solution to regional water management challenges, with a view to achieving improved agricultural production and food security in China and other countries with similar issues. Thus, in the growing quest for economic growth, and owing to the growing need for water in the country, the government of China should ensure through a properly monitored policy framework that water resources are not exploited by a particular sector or region at the expense of other regions in the country.

Abstract. Finding an effective way to deal with the water crisis and the relationship between water and development is a major issue for all levels of government and different economic sectors across the world. Scientific understanding of water risk is the basis for achieving a scientific relationship between water and development, and water risk assessment is currently an important research focus. To effectively deal with the global water crisis, the World Wide Fund for Nature and German Investment and Development Company Limited proposed the concept of water risk and released an online Water Risk Filter in March 2012, which has been applied to at least 85 countries. To comprehensively and accurately reflect the situation of water risk in China, this study adjusts the water risk assessment indicators in the Water Risk Filter, taking the actual situation in China and the difficulty of obtaining the information about the indicators into account, and proposes an index system for water risk evaluation for China which consists of physical risk, regulatory risk and reputational risk. The improved Water Risk Filter is further used to assess the sources and causes of the water risks in 10 first-class and seven second-class water resource areas (WRAs). The results indicate that the water risk for the whole country is generally medium and low, while those for different regions in the country vary greatly, and those for southern regions are generally lower than those for northern regions. Government regulatory and policy implementation as well as media supervision in northern regions should be strengthened to reduce the water risk. The research results may provide decision support and references for both governments and industrial enterprises in identifying water risks, formulating prevention and control policies, and improving water resources management in China.

Abstract Water is scarce in China. The country ekes by with only one-quarter of the global average for water per person. The scarcity is exacerbated by rampant pollution—with devastating consequences on ecosystems, food supply and public health. In the face of growing population, water pollution threatens the very survival of the Chinese nation. In his speech at the 19th National Congress of the Communist Party of China last October, President Xi Jinping repeatedly emphasized the importance to redress the balance between economic development and environmental protection. One of his most frequently cited phrases is ‘clean waters and lush mountains are gold and silver’. And he has matched his rhetoric with action. In April 2015, the State Council, China's cabinet, issued the Water Pollution and Control Action Plan (known as Shuishitiao or Water Ten Plan)—widely hailed as the toughest and most comprehensive water policy to date. Last October, it announced a five-year plan to tackle water pollution, with a budget of 700 billion yuan (US$106 billion). The country's top legislature has also revised the Water Prevention and Control Law, which will go into effect in early 2018. In a forum chaired by National Science Review’s Executive Editor-in-Chief Mu-ming Poo, a panel of experts of diverse backgrounds and perspectives discussed the current status of China's water resources, their views on the comprehensive policy package, how national initiatives have been going, what the challenges are and why information transparency and public participation are absolutely essential in environmental protection.

China is one of the thirteen countries in the world that lacks water. Rapid economic growth and urbanisation over the past two decades have exerted enormous pressure on China's water resources. The shortage of water resources and serious water pollution have become important factors restraining the sustainable development in the cities. Wastewater reuse has been proven to prevent water pollution and ameliorate the pressure on the water environment. Moreover, wastewater reuse can make up for the lack of funds in wastewater treatment. So, wastewater reuse is a viable choice to realise the sustainable utilisation of water resource in China. There still remain many uncertainties in wastewater reuse. It is strongly recommended that a wastewater reuse policy be pushed forward considering the necessity and the implications to society, the economy and the environment. Strategic environmental assessment (SEA) is seen as an important tool for integrating the environmental factors into decision-making. This paper illustrates a case study for SEA — aimed at Tianjin Wastewater Reuse Policy (TWRP). The process of SEA at the policy level and the related problems are presented within this case study. It provides a good framework for carrying out SEA of waste reuse at the national level. The study will support the Chinese Government in developing a national strategy on urban wastewater reuse through an investigation of the existing situations, evaluation of policy options in different areas, and offering recommendations.

With the rapid development of China’s economy, the demand for water resources continues to sharply increase, which has gradually contributed to serious environmental problems. The Chinese government has proposed establishing a natural resource balance sheet, which is expected to solve this problem by assessing the value of water resources. The main purpose of this study was to assess the value of water resources in Wuhan from 2013 to 2017. Based on a fuzzy mathematical evaluation model, 15 indicators were chosen considering the three main aspects of resources, society, and the environment to construct a water resource evaluation indicator system. In addition, the analytic hierarchy process (AHP) and entropy weight methods were combined to determine the index weight. Based on this, we calculated the value of water resources in Wuhan from 2013 to 2017. The results demonstrated that the values of water resources in Wuhan from 2013 to 2017 were US$2.910 billion, US$5.006 billion, US$9.223 billion, US$14.167 billion, and US$7.189 billion, respectively. Therefore, this paper provides a scientific foundation for the rational establishment of water prices, the assessment of local natural resource assets, and the preparation of natural resource balance sheets.

Water resources management practice has undergone changes in management approaches and principles over time. It was previously characterised by what scholars refer to as the hydraulic mission where Âextreme engineering was the order of the day (Allan, 2003). As Radif (1999) argues, water resources managers and policy makers were initially driven to manage and supply water to people for its direct usethese included drinking, growing food, and providing power for domestic and industrial use. This modus operandi continued until the end of the 1970s. Over two decades later, this focus is still prevalent in many countries in southern Africa including Botswana. As Swatuk and Rahm (2004) state, Âaugmenting supply is a continuing focus of government activityÂ. The National Water Master Plan (NWMP) is the current policy document guiding water resources management in Botswana and it focuses on supply-side interventions in response to increasing water demand. According to SMEC et al. (1991), the consulting company that conducted the NWMP study, Âthe investigation and studies... indicated the need for the continuing development of water supplies throughout Botswana over the next 30 yearsÂ. Based on these observations, government has developed significant human and technical capacity in exploiting both surface and groundwater resources (Swatuk and Rahm, 2004).

Thesis (MA)--Stellenbosch University, 2000.ENGLISH ABSTRACT: This dissertation presents aspects of the public policy process in South Africa with specific reference to water policy between 1994 and 1999. For the purposes of this research, the definition of water policy coincides with the government's definition as contained in the Reconstruction and Development Programme (RDP), the Growth, Employment and Redistribution Programme (GEAR), white papers, bills and legislation. Water policy is a broad subject and is approached from a social sciences focus in this study, in that it uses the fulfilment of human needs as a point of departure. Water policy that applied before 1994 was based on water legislation of 1956, as well as some eighty different Acts that were fragmented between a number of institutions. The focus was on water rights, linked to property rights from which the majority of South Africans were excluded. In the implementation of policy attention was mainly paid to engineering achievements. The acknowledgement that water resources are limited in South Africa, as well as in the rest of the world, and the increasing demands on these sources, focused the attention anew on responsible water policy. Since South Africa's transition to an inclusive political democracy in 1994, a variety of far-reaching changes took place with regard to political decision-making and the public policy process. Not only did the policy-making process change, but policy goals, actors, structures and organisations also changed. It is clear that the policy agenda differs significantly from that of the period preceding 1994. In this study, the context within which policy renewal took place in South Africa since 1994, has been presented, and the policy process that new water legislation was subjected to, is described. The role of policy actors and communities - in line with the principles of the Constitution of 1996 that encourage public participation in the democracy - is considered. The implementation of the new water policy could unfortunately not be evaluated as it has only been promulgated a year ago. This study serves as an introduction to a research area which has received little attention thus far and that has potential for further research.
AFRIKAANSE OPSOMMING: In hierdie studie word aspekte van die openbare beleidproses in Suid-Afrika ondersoek met spesiale verwysing na waterbeleid tussen 1994 en 1999. Waterbeleid is vir die doeleindes van hierdie studie omskryf soos in die regering se HOP, GEAR, witskrifte, wetsontwerpe en wetgewing. Waterbeleid is 'n breë onderwerp wat in hierdie studie vanuit 'n sosiaal wetenskaplike hoek benader is, naamlik dat daar aan basiese menslike behoeftes voldoen moet word. Die waterbeleid wat voor 1994 gegeld het, was gebaseer op die Waterwet van 1956, asook wetgewing wat oor tagtig wette versprei was en deur 'n aantal instellings gefragmenteer is. Die klem het geval op waterregte, gekoppel aan eiendomsregte waarvan die grootste deel van die Suid-Afrikaanse bevolking uitgesluit was. Klem is ook gelê op ingenieursprestasies in die uitvoering van beleid. Die besef dat waterbronne wêreldwyd en in Suid-Afrika beperk is met toenemende aansprake wat daarop gemaak word, het opnuut die aandag op verantwoordelike waterbeleid gevestig. Sedert Suid-Afrika se oorgang na 'n inklusiewe politieke demokrasie in 1994 is verskeie verreikende veranderings ten opsigte van politieke besluitneming en die openbare beleidproses ingestel. Nie alleen het die beleidmakingsproses verander nie, maar beleidsdoelwitte, -akteurs, -strukture en -organisasies het ook verander. Kortom, die beleidagenda verskil van die periode voor 1994. In hierdie studie is die konteks van beleidvernuwing in Suid-Afrika na 1994 geskets, en die beleidproses waardeur nuwe waterwetgewing gegaan het, is beskryf. Die rol van beleidakteurs en -gemeenskappe - in lyn met die beginsels van die Grondwet van 1996 wat openbare deelneming aan die demokratiese bestel aanmoedig - is ondersoek. Die implementering van die nuwe waterbeleid kon egter nie geëvalueer word nie, aangesien dit skaars 'n jaar gelede gepromulgeer is. Hierdie studie dien as 'n inleiding tot 'n navorsingsveld wat steeds braak lê met moontlikhede vir verdere navorsing.

Testo completoAbstract (sommario):
Jamaica has an abundance of freshwater resources, however, a lack of infrastructure makes treated, piped water inaccessible in many areas. Through literature reviews and site visits, this thesis is an analysis of how the people and land, and money and policy, interact with one another in relation to Jamaica's freshwater resources and water infrastructure. Special attention is given to the island's type-example Cockpit karst geology; tourism, mining, and farming's relation to this karst; types of water delivery systems in rural southern Trelawny's Cockpit Country; southern Trelawny residents' perceptions of the water situation; and policy and development goals in the context of Jamaica and southern Trelawny. I hope to bring attention to the unique social, geologic, and developmental context of water in Jamaica, and more specifically to garner attention for major water infrastructure improvements in south Trelawny. A number of recommendations for improvements with policy and infrastructure are made.

Thesis (MSc)--Stellenbosch University, 2002.ENGLISH ABSTRACT: A vast literature on the incompatibility of socio-economic development and environmental conservation (also referred to as sustainable development) has developed over the past few years. This study takes on the form of a critical, problemdriven discussion and evaluation of the applicability and viability of the concept of capacity-sharing to the current South African water management regime. Within the study, the complexities involved in the shift from a supply- to demandoriented management strategy are examined in depth. This transition in strategy proves to be problematic for water policy makers and managers because of past management regimes and structures, measurement related problems, incorrect or insufficient definition of criteria needed for demand-oriented approaches and the emotional complexities regarding water use. Developments in water policy are currently at a point where problems are experienced regarding the practical implementation of proposed water demand-oriented policy. The concept of capacity-sharing is explained and discussed in detail, leading to the identification of the applicability to three of the most important problems (basic contradiction within the 1998 National Water Act, initial allocation for market adoption and equity within the market) faced within the transition towards a demand-oriented approach. This study found that the concept of capacity-sharing does hold applicability in addressing the above-mentioned three problems towards the transition to a demand-side management approach. Capacity-sharing, therefore, should be part of this timely transition and the state should make use of the advantages of this concept. To support this view, seven studies are proposed for further research to address the problems as mentioned in section 5.2 of the thesis.
AFRIKAANSE OPSOMMING: 'n Uitgebreide literatuur aangaande die onversoenbaarheid van sosio-ekonomiese ontwikkeling en omgewingsbewaring (ook volhoubare ontwikkeling genoem) het oor die afgelope paar jaar ontwikkel. Hierdie studie neem die vorm van 'n kritiese, probleemgedrewe bespreking ten opsigte van die toepasbaarheid en relevansie van die konsep van kapasiteitsdeling binne die orde van huidige Suid Afrikaanse waterbestuur, aan. Die vele aspekte van die klemverskuiwing van 'n aanbod- na 'n vraag-georiënteerde waterbestuur-strategie, word ook beklemtoon. Hierdie oorgang is problematies vir waterbeleid-formuleerders en bestuurders as gevolg van vorige waterbestuur-ordes en strukture, meetbaarheid georiënteerde probleme, foutiewe of onvoldoende definieering van watergebruik-regte en die emosionele kompleksiteite van water. Tans, word probleme rakende die praktiese implementering van voorgestelde vraag-georienteerde waterbeleid ervaar. Die konsep van kapasiteitsdeling word in detail verduidelik en bespreek waarvandaan die toepasbaarheid op drie van die belangrikste probleme (basiese kontradiksie binne die 1998 Nasionale Waterwet, aanvanklike verdeling van water gebruik regte vir opname binne die mark en die kwessie van regverdigheid binne die mark) vir die oorgang na 'n vraaggeoriënteerde strategie geïdentifiseer word. Die studie het bevind dat die konsep van kapasiteitsdeling wel relevansie ten opsigte van die bogenoemde drie probleme tydens die oorgang na 'n vraag-georiënteerde strategie, inhou. Kapasiteitsdeling behoort dus deel te vorm van die oorgangsfase na 'n vraag-georiënteerde water bestuur strategie en die staat behoort gebruik te maak van die konsep se voordele. Ter ondersteuning hiervan word sewe studies voorgestel vir verdere navorsing ten opsigte van die probleme soos geïdentifiseer in afdeling 5.2 van die tesis.

Testo completoAbstract (sommario):
The North Platte Natural Resources District (NPNRD) is one of 23 quasi-governmental organizations in the state of Nebraska that are organized by river basin and are responsible for the management of groundwater. Conversely, the state's surface water is governed by the Nebraska Department of Natural Resources under the system of prior appropriation. This study uses Foucauldian neoliberal governmentality and a contrasting theory of 'meandering' to explore the conflicting beliefs, perceptions and values that form the foundations of different notions of 'efficiency' as it pertains to water use and management in NPNRD while a political ecology lens is used to situate local perceptions within the regional context of the Platte River Basin. Study findings ultimately point to the remaining 'disintegration' of water governance despite the state's efforts to create legislation that seeks to merge ground and surface water management in practice.

The water resources management regime has shifted from one focusing almost exclusively on augmenting supply to one where ensuring access, equity and sustainability are an integral part of the process. A growing demand for water and the fact that the amount of fresh water is constant raises the impression of water scarcity will occur. Indications are that the notion of access to water for basic needs as well as access to productive water underpins perceptions of scarcity. This thesis interrogated perceptions of scarcity in a small rural community in order to understand the role water can play in developing sustainable livelihoods.

This thesis presents an account of water policies in Alberta's South Saskatchewan River Basin in reference to the historical factors influencing past decisions, the claims supporting present reforms and implications for future policy directions. I begin by investigating the historical factors surrounding early water policies and consider their influence on water development in the 20th century. Next I critically examine the policy reforms from 1996-2006 and consider both how early policy decisions influence contemporary plans and the claims offered in support of current management decisions. I then look to the future of water policy in southern Alberta and the planned implementation of adaptive management systems. I analyze adaptive management theory in the policy context of Alberta and find the normative claims of adaptive management insufficient. I then suggest a more robust normative framework to supplement adaptive management theory.

Testo completoAbstract (sommario):
Public participation in water management processes is one of the internationally recognised and adopted principles of Integrated Water Resource Management. The South African Department of Water Affairs and Forestry aims to facilitate the decentralisation of water management powers to the local community level via the establishment of regional and local water management institutions, namely Catchment Management Agencies, Water User Associations and Catchment Forums. The National Water Act (No. 36 of 1998) acknowledges that the discriminatory laws and practices of the past have prevented equal access to water and the use of water resources. The contribution of water management institutions to social and economic development, in particular poverty eradication and food security, is mentioned in the water act. The participation of poor rural communities living in the Kat valley, an area where an elite minority reap the benefits of water use for agriculture, is the focus of this research. Their participation, perceptions and experiences are documented and explored to determine how the promulgation of post-apartheid water policy and legislation has affected their access to water. The results of this research are based on data collected from several methods including surveys, workshops and observation. Analysis of these data revealed the complicated and stagnant nature of participation from Kat valley rural communities in local water management initiatives and organisations. Existing water management organisations were not successful in stimulating poor people’s participation as they were unable to address their primary concerns, namely a secure source of potable water, employment and access to water for agricultural purposes. This thesis asserts that the Department of Water Affairs and Forestry, as the custodian of South Africa’s water resources, has not taken on a supportive, accountable role in assisting marginalised communities with improving their access to water for domestic purposes and securing access to water rights for productive use. This, in turn, has led to dissatisfaction among these communities and a wariness of participatory activities that focus mainly on raising environmental awareness. The establishment of effective accountability relationships among all stakeholders, pro-poor water management structures and initiatives, as well as integrated and co-operative management of natural resources, are needed to revitalise the present participation of poor communities living in rural areas.

Testo completoAbstract (sommario):
Payment for Environmental Services (PES) in the watershed has been widely adopted as an important policy instrument to compensate upstream water users for providing water quality improvement for the whole river basin. In this paper, we use three independent valuation methods to determine the price of ecosystem service (ES), particularly water quality, in Miyun Reservoir, the main surface water source for Beijing. We find that the value of water quality is lowest using opportunity cost of limitation of development rights (OCLDR), highest with contingent valuation method (CVM), and water resources benefits assessment (WRBA) gives an in-between value. OCLDR determines the size of subsidies from those that benefit from water quality improvement from upstream. WRBA is a reference for compensation criteria to the upstream government and farmers when water resources are transferred across jurisdictional boundaries. CVM not only captures the direct value of water quality improvement, but also the indirect value of improvement in other ecosystem services as a result of improvement in water quality. Based on the results, we propose a multi-level ecological compensation system for the Miyun Reservoir river basin. We use OCLDR to determine subsides/ compensation to upstream farmers and other suppliers of the ES; WRBA set the price of water transfer; and CVM to figure out the size of payments for integrated water quality improvement.

Testo completoAbstract (sommario):
The environment provides the economy with resources (e.g., water, air, fuels, food, metals, minerals, and drugs), services (e.g., the cycles of H2O, C, CO2, N, O2; photosynthesis, and soil formation), and mechanisms to absorb waste. Economic growth is based on these three services, and since the global ecosystem does not grow, economic growth cannot continue indefinitely. The concepts of sustainability and sustainable development have received much attention among policy-makers and scientists as a result of the existence of limits to growth and the dramatic environmental changes of the last decades. Sustainability integrates environmental, economic, and societal aspects. It also covers different geographical scales: ecosystems, regions, countries, and the globe. In this chapter, the authors review various models of sustainability assessment. Since there is no universally accepted definition and measuring technique of sustainability, these different models lead to different assessments. They also present a discussion of the sustainability indicators, aggregation tools, and data imputation techniques used in each approach.

Testo completoAbstract (sommario):
Of all the livelihoods made possible by land development, Cory Breternitz’s job was one of the more peculiar. He was paid to do archaeological excavations by people who hoped he would find nothing of interest. His Phoenix-based firm was one of many private archaeology firms that sprang up in response to legislation (the National Historic Preservation Act of 1966 and the National Environmental Policy Act of 1970) designed to protect cultural resources such as prehistoric artifacts or remains. These laws require government agencies and private developers to hire historians and archaeologists to survey sites and inventory the results before they start building. At the height of the Arizona housing boom, Breternitz, who had previously worked for the Navajo Nation for more than twenty years, spent much of his time on the urban fringe, sifting through desert soil, looking for evidence of Hohokam settlement before the bulldozers “scraped the desert clean” and the construction crews moved in with chipboard, two-by-fours, and stucco to throw up a brown-tiled subdivision. If Breternitz uncovered a prehistoric structure, even a hamlet, it was still the developer’s prerogative to plough it under. “The United States,” he explained, “is different than most countries in the world in that private property is sacred, and the government cannot tell you what to do with it. In places like England, historic properties on your land belong to the Crown, and whatever you find—like a hoard of medieval coins—belongs to the government. In the U.S. if you find a ruin on your land, it belongs to you and you can bulldoze it or sell the artifacts.” Some of the developers he worked for might decide to preserve his discoveries and have them curated on-site by the state so that they could be promoted as an attractive sales feature to add value to the development. But ultimately, he reported, most of them simply “want their clearance, or their permits, to move forward with their projects and make money.” Human remains are the exception to this rule, since private ownership of these is prohibited by federal and Arizona law.

Testo completoAbstract (sommario):
In 2007 the Chinese government nationally implemented the rural dibao programme. The chapter argues that while the circumstances of rural dibao’s implementation were different from its urban predecessor there are three striking similarities. First, in terms of values, it is argued that the rural dibao programme did fit comfortably with the agenda under Hu Jintao and Wen Jiabao to address China’s unequal development and in particular the san nong wenti of the countryside. However, the process surrounding implementation of the rural programme also carried appeals to social stability. Second, the political structure had a significant impact on the implementation of the rural MLG. As with the urban programme implementation faced local intransigence. This was overcome by not only using similar means as with the urban programme; but also through explicitly dealing with one common source of problems, funding. Finally, there is the problem of administrative capacity in running the rural MLG programme. This appears as a classic outcome of the fragmented political and decision making structure in China where local government, often struggling to meet mandates passed down from above, prioritises the resources it has. What this all shows is that the challenges facing social assistance in China are not specific to the urban or the rural programme; but are a consequence of the structure of the state.

Testo completoAbstract (sommario):
Farm forestry, interchangeably used for the term agroforestry, encompasses growing trees and/or shrubs on farms, mainly to support agricultural production and supplement farm income on smallholder farms. This, as a bonus, also provides for ecosystem services viz., protection of soil and water resources, biodiversity enhancement, carbon sequestration, and improvement in landscape values to the farm holding. In Indian context, this encompasses raising trees mainly on bunds or field boundaries on small holdings or sometimes intercropped in an agroforestry type configuration, if holding size is bigger. The techno-economic viability of this system has been extensively assessed and wide adoption, therefore, warrants a conducive policy support at local and community level. Governments have framed enabling policies towards this goal; however, desired outcome is still awaited. This study attempts to map out the present development and suggest the measures required at local and community level to make the government policies more fruitful. Policies framed at macro level need recalibration to suit local and community specific requirements in the changing climatic conditions for wider adoption and sustenance.

<em>Abstract</em>.—The Yangtze River is the largest river in China, with a drainage area encompassing a land area of 1.8 × 10<sup>6</sup> km<sup>2</sup>. The river main stem flows approximately 6,300 km from west to east through 11 provinces, eventually emptying into the East China Sea. The total basin area of the Yangtze River provides more than 40% of China’s gross domestic product, sustains nearly 500 million people, and plays a vital role in the overall socioeconomic development of China. Because of longitudinal differences in geomorphology, the Yangtze River is often divided into upper, middle, and lower reaches for the purposes of study and description. In general, the Yangtze River basin has a warm climate and abundant rainfall. The subtropical monsoon climate accounts for 70–80% of its annual rainfall, which produces predictable annual flood events during summers of each year. The Yangtze River ecosystem also has diverse aquatic habitats that support high biodiversity. The Yangtze River main stem contains more than 3,000 tributaries and approximately 4,000 lakes that provide important habitats for thousands of aquatic species, which include 378 fish species. Yet, the ecological communities of the Yangtze River have been dramatically impacted in recent decades due to high degrees of anthropogenic activities associated with the economic development of China. Significant biodiversity declines occurring throughout the basin have been largely attributed to hydropower dam construction, overexploitation of major fisheries, water pollution, and habitat fragmentation. In addition, widespread disconnection of the Yangtze River main stem from its floodplain lakes, lake reclamation projects, invasions by exotic species, and other serious ecological problems threaten the survival of the remaining aquatic resources in the basin. To offset the adverse effects of these threats, a number of nature reserves have been established. Additionally, protection and restoration measures, including spring fishing closures, artificial population enhancement strategies, and complete habitat restoration projects, have been implemented throughout the basin. Although these projects have yielded some encouraging results to date, they are still considered inadequate. It is recommended that an integrated strategy that includes cross-functional communication mechanisms, more comprehensive monitoring, ecological rehabilitation, and government legislation is still needed. This will insure that utilization and development in the Yangtze River ecosystem are sustainable and balanced with conservation and ecological needs.

<em>Abstract.</em> —The Canada-U.S. Great Lakes Water Quality Agreement (GLWQA) is an evolving instrument for ecosystem-based management. Its initial emphasis in 1972 was on controlling phosphorus inputs.

The 1987 Protocol to the GLWQA adopted new annexes mat focused on sources and pathways of persistent toxic substances and on development and implementation of comprehensive management plans to restore beneficial uses, including fish and wildlife habitat. Canada and the United States have achieved a number of Great Lakes successes. Examples of successes include: reversing cultural eutrophication in the lower Great Lakes and maintaining the oligotrophic-mesotrophic state of the upper Great Lakes as a result of phosphorus control programs, and achieving US$2-4 billion in economic return to the Great Lakes region annually as a result of fish stocking, restrictions on harvests, and sea lamprey control. As such successes have been achieved and cooperative management efforts have evolved to address ecosystem integrity and sustainability, the relative importance of habitat as a Great Lakes issue has increased. Current major challenges to further ecosystem-based management of habitat include: ensuring that all levels of government adopt strong habitat conservation and rehabilitation policy statements; recruiting and retaining trained habitat personnel to ensure that local and regional actions are consistent with such policies; sustaining creative ecosystem-based processes in light of government cutbacks; addressing the need for fish habitat assessment and analysis via effective institutional arrangements; agreeing on a core set of indicators and allocating required resources to sustain monitoring programs; and exchanging information about successful experiences with modifying habitat to support fish stocks and communicating broadly both ecological and economic benefits.

Testo completoAbstract (sommario):
Abstract The Petroleum Working Group (PWG) of the United Nations Economic Commission for Europe (UNECE) has developed the Petroleum Resource Specifications and Guidelines (PRSG) to facilitate the application of the United Nations Framework Classification for Resources (UNFC) for evaluating and classifying petroleum projects. The UNFC was developed by the Expert Group on Resource Management (EGRM) and covers all resource sectors such as minerals, petroleum, renewable energy, nuclear resources, injection projects, anthropogenic resources and groundwater. It has a unique three- dimensional structure to describe environmental, social and economic viability (E-axis), technical feasibility and maturity (F-axis) and degree of confidence in the resource estimates (G-axis). The UNFC is fully aligned to holistic and sustainable resource management called for by the 2030 Agenda for Sustainable Development (2030 Agenda). UNFC can be used by governments for integrated energy planning, companies for developing business models and the investors in decision making. Internationally, all classification systems and their application continue to evolve to incorporate the latest technical understanding and usage and societal, government and regulatory expectations. The PRSG incorporates key elements from current global petroleum classification systems. Furthermore, it provides a forward-thinking approach to including aspects of integrity and ethics. It expands on the unique differentiator of the UNFC to integrate social and environmental issues in the project evaluation. Several case studies have been carried out (in China, Kuwait, Mexico, Russia, and Uganda) using UNFC. Specifically, PRSG assists in identifying critical social and environmental issues to support their resolution and development sustainably. These issues may be unique to the country, location and projects and mapped using a risk matrix. This may support the development of a road map to resolve potential impediments to project sanction. The release of the PRSG comes at a time of global economic volatility on a national and international level due to the ongoing impact and management of COVID-19, petroleum supply and demand uncertainty and competing national and international interests. Sustainable energy is not only required for industries but for all other social development. It is essential for private sector development, productive capacity building and expansion of trade. It has strong linkages to climate action, health, education, water, food security and woman empowerment. Moreover, enduring complex system considerations in balancing the energy trilemma of reliable supply, affordability, equity, and social and environmental responsibility remain. These overarching conditions make it even more essential to ensure projects are evaluated in a competent, ethical and transparent manner. While considering all the risks, it is also critical to reinforce the positive contribution a natural resource utilization project provides to society. Such an inquiry can focus on how the project contributes to the quality of life, environment, and the economy – the people, planet, and prosperity triad. Such an approach allows consistent, robust and sustainable investment decision making and energy policy development.

Testo completoAbstract (sommario):
In geopolitics, the concepts of geography and territory are reduced to the fundamental aspects of relations between States, they serve as a basic method of interpreting the past, they act as the main factors of human existence, organizing all other aspects of existence around them. It is in this perspective that the article examines the attitude to Baikal in the history of the mutually linked foreign policy of Russia and China. It is noted that the Mongols and Manchus, who once conquered China, not only found themselves largely assimilated by the defeated society, but over time, a large part of their ancestral territories began to be perceived as native Chinese. Far from being justified, this also applied to Baikal, although the Yakut etymology of its name, associated with the ethnic ancestors of the Yakuts — the Huns, has been clearly traced since ancient times. Since ancient times, Buryats and Evenks who voluntarily became part of Russia have lived around Baikal. Modern development is characterized by the “penetration” of the Chinese into the business of Asian Russia. In the Baikal region, this focus has basically three goals: forest, clean water, and ownership of land and other natural resources. In a special row, it is necessary to put projects for supplying the population of some Chinese territories with Baikal water, which is planned to be transported both in bottled form and in the future through pipes.

Recently, Korean Government is encouraging to propagate the small hydro-electric power in renewable energy development policy as the “Low CO2 Green Growth” policy. However, turbines in the Korea Water Resources Corporation (below K-water) operated at an average of 10% less than well-designed turbines due to the design weakness or the inferior manufacturing techniques for the small hydropower facilities. Thus, maintenance fees increased because the cavitations had excessively occurred on the main parts of turbines such as the runner, guide vane and Stator, the life cycles of turbines were reduced and the frequency breakdowns were increased. In order to improve the efficiency the CFD-based design system is applied to the Francis turbine replacement project with Korea Fluid Machinery Association (below KFMA) and K-water. Therefore, the inversed design technique and the fully turbulent 3-dimensional flow simulations are performed for both the existing and new turbines at design and off design conditions. As a result, the runner is optimized to the greatest extent with a possible minimum cost under the geometrical constraints of the existing machine. The performances of the new design are verified by extensive model tests and the guarantees have all been successfully met.

The global water nexus is still in the formative stages as a area of study. The needs are mostly clear: people need adequate water for drinking, for growing food, for cooling steam-based power plants, and for sustaining the natural habitats that keep the carbon and hydrologic cycles functioning properly. What has emerged is a growing awareness of how finite the earth’s water resources are and how this creates a complex set of interconnected challenges in both developed and developing nations. What has also emerged are predictions with increasing urgency for water and energy crises in the next 20–50 years, especially if these concerns are left unaddressed. The Water-Nexus is not new, but its emerging importance now is driven primarily by population growth, climate change, and our growing awareness of societal impact on ecosystems. Providing energy for buildings, homes, and transportation is an increasingly difficult task for the growing population and aging infrastructure. Most individual issues within the Water-Energy Nexus are fairly well known with quantifiable water impacts. What is lacking is a clear representation of the Nexus relationships that show how changes in one sector impact another. What is needed is a compact way to represent the interrelationships that provide both insight and perspective on how much influence one proposed change has compared to another. Such an understanding should surface the most strategic, viable methods for simultaneously meeting water and energy needs while being a good steward of finances and natural resources. We propose the use of decision matrices from engineering design to represent the interconnected relationships that form the Water-Energy Nexus. The customers in this case are water-centric stakeholders such as government and corporate decision makers, educators, and water-oriented development agencies. Both quantitative and qualitative research methods are used to integrate the nexus topics into the decision matrix. Both positive and negative correlations in water impacts are indicated with their relative level of influence. Common units are used when possible to quantify water consumption or savings. Decision matrices are presented for transportation fuels and utility power generation. The transportation fuels matrix includes evaluation criteria for water impact, sustainability, convenience, emissions, public opinion, and geographic considerations. The utility power decision matrix has similar evaluation criteria except capacity factor is considered instead of convenience. These criteria are intended to aid policy makers in strategically navigating the legislative and policy generation process to emphasize or reduce emphasis on different fuel types. Recommendations are provided for strategic, viable methods to mitigate future effects of the Water-Energy crisis.

Testo completoAbstract (sommario):
The application of new lubrication technology has a close relationship with the industrial development of automobile, machinery and transportation. Energy saving and environment protection are main two factors to push lubricants upgrades. Lubricant quality and correct application directly influence the use-life of machine, consumption of energy and environment protection. All over the world, especially in Western developed countries people pay more attention to the research and application of new lubricant technology. The lubricant specifications were reviewed and upgraded continuously according to the requirements of machine, fuel economy and emission. China’s sustained development means the ability to satisfy current human’s requirement as well as not to destroy nature resources for next generation. That also means we must balance the fast development of economy, society, resources and environment, we must protect natural resources and environment such as water, ocean, lands and forest which we live on, which can keep our next generation developing. Research and application of new lubricant technology is basic issues to keep China’s economy continuously growing. China’s petroleum consumption increased rapidly during the recent decades. There are two rapid period within 25 years after China’s application of opening and reform policy. The first is from 1978 to 1990, the whole petroleum consumption increased from 913 million to 1.18 billion tons respectively, increasing rate is 2.0% per year. The second was from 1991 to 2003, petroleum consumption increased from 1.18 billion to 2.74 billion tons, increasing rate was up to 6.7% per year. If we compare 2003 with 2001, the net petroleum consumption amount had increased 42million tons, increase rate is 8.7% per year. China now becomes one of biggest petroleum consumption country. The efficiency of China’s petroleum consumption is low. According to world petroleum consumption level (ton per thousand U.S. Dollar, GDP), China consumes four times more petroleum than that of Japan, three times of that of European, two times of that of USA. The wide application of low-grade lubricating oil and the lack of new lubrication technology are the main cause of the low-efficient petroleum usage. In the future decades petroleum shortages will be more and more strict in China, and it will have an important role in the delay of economic development and national safety. It is our lubricants workers duty to develop and apply the new lubrication technology to enhance the use efficiency of petroleum, to prevent our reliable environment and to push the China’s sustainable development. The world total consumption quantity of lubricating oil keeps about 37 to 39 million tons per year. It shares about 1% of total crude refining amount. The lube consumption amount in North American keeps stable about 9.5 million tons which listed No.1 while European and previous Unit Soviet area decreased. Asia is the only increased area, mainly because of the fast economic growth in China and India. China has consumed 4.4million tons lubricating oil in 2003, take about 1.6% of total crude refining amount, shares about 11% of whole world consumption amount, values about 22 billion RMB [1]. The increased rate reaches the highest—10.56% compared to 2002. This was the first time China become the second lubricant consumer in the world, just after USA. In 2004, China’s lubricants consumption will reach over 5 million tons, reaches the top in history, the increased rate will reach 10% comparing with 2003. China’s Automobile industry develops rapidly in the recent years, at the same time fuel efficiency keeps a low level. In 2002 China’s automobile has consumed 2.28 ton fuel per automobile which is 110–120 percent of USA, 200 percent of Japan. There exists a wide market for the application of new lubrication technology. The application of those additives and lube oils such as environment-friend additives, friction modified agents, nano-lube additives, energy-conserving multi-grade lube oils can enhance lubrication efficiency of equipments, decrease fuel consumption and conserve the petroleum resources. In this paper the applications of Cu nano-lube additive are introduced. and 0.1% Cu nano-lube is added into passenger car motor oil 5W30 SJ. The four-ball test equipment, cam-tappet test equipment and MS VI engine test are used to evaluate the performance, the test results shows the application of Cu nano-additive can obviously decrease the friction coefficient and fuel consumption. China should establish its national lube oil evaluation system, this system can greatly push the warranty of the quality of lube oil. The standard and national principle for fuel-conserving should be acted to improve the application of multi-grade lube oil and energy-conserving lube oil and new technology.

Testo completoAbstract (sommario):
In the past 40 years, China has experienced the largest and fastest urbanization development in the world. The infrastructure, urban environment and medical services of cities have been improved significantly. The health impacts are manifested in the decrease of the incidence of infectious diseases and the significant increase of the life span of residents. However, the development of urbanization in China has also created many problems, including the increasing pollution of urban environment such as air, water and soil, the disorderly spread of urban construction land, the fragmentation of natural ecological environment, dense population, traffic congestion and so on. With the process of urbanization and motorization, the lifestyle of urban population has changed, and the disease spectrum and the sequence of death causes have changed. Chronic noncommunicable diseases have replaced acute infectious diseases and become the primary threat to urban public health. According to the data published by the famous medical journal The LANCET on China's health care, the economic losses caused by five major non-communicable diseases (ischemic heart disease, cerebrovascular disease, diabetes mellitus, breast cancer and chronic obstructive pulmonary disease) will reach US$23 trillion between 2012 and 2030, more than twice the total GDP of China in 2015 (US$11.7 trillion). Therefore, China proposes to implement the strategy of "Healthy China" and develop the policy of "integrating health into ten thousand strategies". Integrate health into the whole process of urban and rural planning, construction and governance to form a healthy, equitable and accessible production and living environment. China is building healthy cities through the above four strategies. The main strategies from national system design to local planning are as follows. First of all, the top-level design of the country. There are two main points: one point, the formulation of the Healthy China 2030 Plan determines the first batch of 38 pilot healthy cities and practices the strategy of healthy city planning; the other point, formulate and implement the national health city policy and issue the National Healthy City. The evaluation index system evaluates the development of local work from five aspects: environment, society, service, crowd and culture, finds out the weak links in the work in time, and constantly improves the quality of healthy city construction. Secondly, the reform of territorial spatial planning. In order to adapt to the rapid development of urbanization, China urban plan promote the reform of spatial planning system, change the layout of spatial planning into the fine management of space, and promote the sustainable development of cities. To delimit the boundary line of urban development and the red line of urban ecological protection and limit the disorderly spread of urban development as the requirements of space control. The bottom line of urban environmental quality and resource utilization are studied as capacity control and environmental access requirements. The grid management of urban built environment and natural environment is carried out, and the hierarchical and classified management unit is determined. Thirdly, the practice of special planning for local health and medical distribution facilities. In order to embody the equity of health services, including health equity, equity of health services utilization and equity of health resources distribution. For the elderly population, vulnerable groups and patients with chronic diseases, the layout of community health care facilities and intelligent medical treatment are combined to facilitate the "last kilometer" service of health care. Finally, urban repair and ecological restoration design are carried out. From the perspective of people-oriented, on the basis of studying the comfortable construction of urban physical environment, human behavior and the characteristics of human needs, to tackle "urban diseases" and make up for "urban shortboard". China is building healthy cities through the above four strategies.

Testo completoAbstract (sommario):
The paper discusses the process of providing walkable pedestrian facilities in cities in Indonesia which is considered lacking due to the limited number and poor quality. In the past few years, the government has been improving and developing the walkable pedestrian through policy and regulation, as well as physical development. This action is also linked to the green city program, in particular, sustainable transportation. However, the physical development and implementation of policy and green city program are not as smooth as expected due to the limitation of urban space, human resources, and finance. The study focuses on identifying problems and introduces arrangements that could improve the quality of pedestrian facilities. It applies interviews, questionnaires, and design competition to gather input from the public. Two cities in Indonesia are selected as the case studies, namely, Bogor and Banjarmasin. In each city, the study selects a location to elaborate for the design competition. The study analyses the walkability condition in each zone using nine parameters that emphasise on pedestrian conflict with other modes, availability of pedestrian path, availability of crossing, the safety of crossing, the behaviour of the motorcyclist, amenities, disable facility, buffer, and security. The finding points general problems such as poor amenities and lack of disabling facility, as well as the problem of motorcyclist behaviour. Besides problems, the study also identifies local potentials that could support the improvement of walkable pedestrian facilities. Those findings are important to improve the pedestrian facilities and develop an understanding of local condition since each city has different characteristics. The study applies those findings as an input to develop policy on the pedestrian facility of the green city for the Ministry of Public Works and Housing. The policy links to the green city program that addresses eight attributes, namely the green planning and design, open green space, green community, green waste, green energy, green transportation, green building, and green water. Further, the policy also emphasises five components of walkability, accessibility and connectivity, attractiveness, comfort and equality, safety, and security. Combination of green city attributes and walkability components are used for the planning-design and development of walkable pedestrian facilities in the urban area in Indonesia.
