Global water: issues and insights
This book brings together some of the world’s leading water researchers with an especially written collection of chapters on: water economics; transboundary water; water and development; water and energy; and water concepts.
Introduction
Freshwater governance holds a prominent position in the global policy agenda. Burgeoning water demand due to population growth and rising incomes is combining with supply-side pressures, such as environmental pollution and climate change, to create acute conditions of global water scarcity. This is a major concern because water is a primary input for agriculture, manufacturing, environmental health, human health, energy production and just about every economic sector and ecosystem.
In addition to its importance, the management of freshwater resources is a complex, multidisciplinary topic. Encompassing a range of fields in the physical and social sciences, the task of sustainably meeting human and environmental water needs requires a depth and breadth of understanding unparalleled by most other policy problems.
Our objective in this volume is to provide knowledge and insights into major issues and concepts related to freshwater governance. The book is divided into five themed parts: Economics, Transboundary governance, Development, Energy and Water Concepts.
A part addresses each theme and opens with an introduction that provides an overview of key topics. For example, the introduction to the economics section presents two main foci: measuring the value of water and managing trade-offs between different water uses. The thematic case studies discuss issues such as water pricing in Organisation for Economic Co-operation and Development (OECD) countries, finance of water supply and irrigation infrastructure and improving agricultural production with enhanced water management.
The aim of the volume is to accessibly communicate academic research from the many fields of freshwater governance. Too often, academic research is paywalled and/or written in a style that caters to colleagues in the same field, rather than a broader audience from other disciplines, the policy-making community and the general public. This open-access book presents the research of a range of global experts on freshwater governance in brief, insightful chapters that do not presume a high level of pre-existing knowledge of their respective subjects. This format is intended to present knowledge on the key problems of and solutions to global freshwater challenges.
The final part presents research from several United Nations Educational, Social, and Cultural Organisation (UNESCO) supported water research Chairs and Centres. Support and coordination of the insititutions highlighted in this part of the book is provided by UNESCO. One water research Chair is The Australian National University – UNESCO Chair in Water Economics and Transboundary Governance, which was established in April 2010 and works with partners in southern Africa, UNESCO, the Global Water Partnership and other organisations to: (1) increase the skills, capacity, networks and potential of leaders and prospective water managers and policy-makers; (2) sustain and strengthen institutional capacity (especially in southern Africa) by providing a platform for collaboration and institutional development; and, (3) develop innovative research, tools, case-studies, and insights on water economics, water governance and equity.
Established by the ANU–UNESCO Chair, the Global Water Forum (GWF) seeks to disseminate knowledge regarding freshwater governance and build the capacity of students, policy-makers and the general public to respond to local and global water issues. The GWF publishes accessible, subscription-free articles highlighing the latest research and practice concerning freshwater governance. A broad range of water-related topics are discussed in a non-technical manner, including water security, development, agriculture, energy and environment. In addition to publishing articles, reports and books, the GWF is engaged in a range of activities, such as the annual Emerging Scholars Award and hosting a portal to educational resources on freshwater.
We hope that you enjoy reading this book and, more importantly, gain an improved understanding of the complex freshwater-governance challenges facing us all on a global scale and at a local level
Determinants of environmental degradation: reflections on the impact of identified economic variables on the environment
Purpose. The main objective of this study is to investigate the determinants of environmental degradation within the broader framework of the environmental Kuznets Curve analysis. To better understand the economic impact on the environment, the study focuses on the relationship between carbon emission and the variables income per capita, trade openness, foreign direct investment, energy use and urbanization.
Methods. In the context of the dynamic carbon emission model a Generalized-Method-of-Moments (GMM) technique was used to analyse World Bank of 125 countries for the period 2000 to 2014. This era was chosen as the most appropriate given the completeness of the dataset.
Findings. The findings indicate that economic growth and energy use are significant variables in explaining environmental degradation, supporting previous research in to the particularly negative impact of energy use on the environment. The research however, found that urbanisation had only marginal significance in explaining the impact on the environment.
Originality. The findings contribute to existing research in the area of environmental degradation, providing insight into the debate surrounding urbanisation and CO2 emission which had previously received mixed results. The findings take research forward through the examination of explanatory variables and their respective impact on CO2 emission in countries which have observed an increase in the number of urban dwellers.
Practical implications. Given the debate in academic and practitioner literature around climate change, pollution and a general concern over a lack of collective action to address environmental concerns, the findings have practical implications for government institutions and businesses to better understand the economic impact on the environment.Мета. Визначення факторів, які викликають екологічну деградацію довкілля в широкому контексті екологічної кривої Кузнеця, на основі вивчення взаємозв’язку між вуглецевими викидами і такими змінними як дохід на душу населення, відкритість торгівлі, прямі іноземні інвестиції, використання енергії та урбанізація.
Методика. Для побудови динамічної моделі вуглецевої емісії були використані дані Всесвітнього банку по 125 країнам у період з 2000 по 2014 роки, проаналізовані за допомогою узагальненого методу моментів. Даний проміжок часу був обраний як той, що найбільш повно представляє базу даних.
Результати. Встановлено, що економічне зростання і використання енергії є найсуттєвішими факторами, які визначають екологічну деградацію, що підтверджується більш ранніми дослідженнями негативного впливу використання енергії на навколишнє середовище. Виявлено, що урбанізація впливає на стан навколишнього середовища тільки побічно. Рекомендовано в наступних дослідженнях розглянути інші заходи для уявлення урбанізації, а саме можливість вивчення даних по великих містах, а не по країнам. Такий підхід може дати додаткове уявлення про вплив урбанізації та можливих відмінностей між містами і регіонами.
Наукова новизна. Отримано нові знання щодо оцінки впливу урбанізації та вуглецевих викидів на навколишнє природне середовище, які раніше мали неоднозначні результати. Прогрес у вивченні даних проблем було досягнуто за рахунок аналізу ключових змінних і їх впливу на емісію CO2 в країнах, де спостерігається зростання міського населення.
Практична значимість. Результати дослідження мають істотне практичне значення для державних установ та бізнесових структур, оскільки допомагають краще зрозуміти сутність економічного впливу на навколишнє середовище і вносять вклад у вирішення проблеми екологічної деградації.Цель. Определение факторов, вызывающих экологическую деградацию окружающей среды в широком контексте экологической кривой Кузнеца, на основе изучения взаимосвязи между углеродными выбросами и такими переменными как доход на душу населения, открытость торговли, прямые иностранные инвестиции, использование энергии и урбанизация.
Методика. Для построения динамической модели углеродной эмиссии были использованы данные Всемирного банка по 125 странам в период с 2000 по 2014 годы, проанализированные при помощи обобщенного метода моментов. Данный промежуток времени был выбран как наиболее полно представляющий базу данных.
Результаты. Установлено, что экономический рост и использование энергии являются самыми существенными факторами, определяющими экологическую деградацию, что подтверждается более ранними исследованиями негативного влияния использования энергии на окружающую среду. Выявлено, что урбанизация воздействует на состояние окружающей среды только косвенно. Рекомендовано в следующих исследованиях рассмотреть другие меры для представления урбанизации, а именно возможность изучения данных по крупным городам, а не по странам. Такой подход может дать дополнительное представление о влиянии урбанизации и возможных различий между городами и регионами.
Научная новизна. Получены новые знания касательно оценки влияния урбанизации и углеродных выбросов на окружающую природную среду, которые ранее имели неоднозначные результаты. Прогресс в изучении данных проблем был достигнут за счет анализа ключевых переменных и их влияния на эмиссию CO2 в странах, где наблюдается рост городского населения.
Практическая значимость. Результаты исследования имеют существенное практическое значение для государственных учреждений и бизнес структур, поскольку помогают лучше понять сущность экономического воздействия на окружающую среду и вносят вклад в решение проблемы экологической деградации.The authors would like to thank Taylor’s University for funding this research project (Source of funding: TRGS (Taylor’s Research Grant Scheme); Grant Project Code: TRGS/ERFS/1/2018/TBS/009)
Industrial development, agricultural growth, urbanization and environmental Kuznets curve in Pakistan
The debate of environmental issues and their analysis is of vital interest for economic policies. Institutions are engaged in identifying and estimating the extent of environmental impact of determinants controllable via policy measures. Annual data from the on Carbon Dioxide emission, economic growth, consumption of energy, openness for foreign trade, urbanization, industrial growth and agriculture growth on Pakistan is used for 1971 to 2007. Augmented Vector Autoregression technique and cointegration analysis is implemented to test Granger causality. Gross domestic product significantly Granger causes emission of Carbon Dioxide and energy consumption. On the other hand emissions of CO2 affect economic growth, agriculture and industrial growth in the long run. It is also evident that energy consumption unidirectional Granger causes emission of Carbon Dioxide. Industrialization and urbanization bidirectional Granger causes each other. The results indicate the more careful industrial and energy policies to reduce emissions and control global warming.Pakistan, Carbon Dioxide emission, Environment, Energy Consumption, Economic Growth, Foreign Trade
The poverty/environment nexus in Cambodia and Lao People's Democratic Republic
Environmental degradation can inflict serious damage on poor people because their livelihoods often depend on natural resource use and their living conditions may offer little protection from air, water, and soil pollution. At the same time, poverty-constrained options may induce the poor to deplete resources and degrade the environment at rates that are incompatible with long-term sustainability. In such cases, degraded resources may precipitate a downward spiral, by further reducing the income and livelihoods of the poor. This"poverty/environment nexus"has become a major issue in the recent literature on sustainable development. In regions where the nexus is significant, jointly addressing problems of poverty and environmental degradation may be more cost-effective than addressing them separately. Empirical evidence on the prevalence and importance of the poverty/environment nexus is sparse because the requisite data are often difficult to obtain in developing countries. The authors use newly available spatial and survey data to investigate the spatial dimension of the nexus in Cambodia, and Lao People's Democratic Republic. The data enable the authors to quantify several environmental problems at the district and provincial level. In a parallel exercise, they map the provincial distribution of poor households. Merging the geographic information on poverty and the environment, the authors search for the nexus using geo-referenced indicator maps and statistical analysis. The results suggest that the nexus is country-specific: geographical, historical, and institutional factors may all play important roles in determining the relative importance of poverty and environment links in different contexts. Joint implementation of poverty and environment strategies may be cost-effective for some environmental problems, but independent implementation may be preferable in many cases as well. Since the search has not revealed a common nexus, the authors conclude on a cautionary note. The evidence suggests that the nexus concept can provide a useful catalyst for country-specific work, but not a general formula for program design.Health Economics&Finance,Environmental Economics&Policies,Agricultural Research,Public Health Promotion,Health Monitoring&Evaluation,Environmental Economics&Policies,Health Monitoring&Evaluation,Poverty Assessment,Energy and Environment,Agricultural Research

Variation of household electricity consumption and potential impact of outdoor PM2.5 concentration: a comparison between Singapore and Shanghai
The auto-regressive distributed lag (ARDL) bound testing approach was used to study the relationships between the monthly household electricity consumption and outdoor PM2.5 concentration with the consideration of ambient temperature and the number of rainy days for Singapore and Shanghai. It is shown that there are significant long-run relationships between the household electricity consumption and the regressors for both Singapore and Shanghai. For Singapore, a 20% increase in the PM2.5 concentration of a single month is in the long-run significantly related to a 0.8% increase in the household electricity consumption. This corresponds to an electricity overconsumption of 5.0 GWh, a total of 0.7–1.0 million USD in electricity cost, and 2.1 kilotons of CO2 emission associated with electricity generation. For Shanghai, a 20% decrease in the PM2.5 concentration of a single month is in the long-run significantly related to a 2.2% decrease in the household electricity consumption. This corresponds to a 35.0 GWh decrease in the overall household electricity consumption, 1.6–5.1 million USD decrease in electricity cost, and 17.5 kilotons of CO2 emission. The results suggest that the cost of electricity consumption should be included in the economic cost analysis of PM2.5 pollution in the future. A 1 °C increase in the monthly temperature is in the long-run significantly related to a 13.6% increase in the monthly electricity consumption for Singapore, while a 30 degree days increase in heating & cooling days (HCDD) is in the long-run significantly related to a 24.9% increase in the monthly electricity consumption for Shanghai. A 5-day increase in the number of rainy days per month is in the long-run significantly related to a 3.0% and 5.8% increase in the monthly electricity consumption for Singapore and Shanghai, respectively
Estimation on Economic Cost of China's New De-sulfur Policy During Her Gradual Accession to WTO: The Case of Industrial SO2 Emission
To understand the potential impacts of China’s accession to WTO in her new de-sulphur policy (reduction of 10% of SO2 emission in 2005 with respect to that of 2000), we construct a CGE model in which the SO2 emission is linked directly to energy intermediary consumption in production. The positive externality of trade on China’s economy is also included. This model is then calibrated into a 55-sector Chinese SAM of year 1997. Four policy simulations (BaU, Open, Desulfur, Open+Desulfur) are made for 1997 till 2005 and the Divisia index decomposition method is used to analysis the simulation results. The principal results show the environmental impact of trade, though proven to be “negative”, stays rather modest. This is due to the effect of industrial composition transformation that deviates towards labor-intensive sector specialization under the new trade liberalization process. We also find supposed some modest trade externality effect to contribute to pollution reduction and we do not find proof for “pollution haven” hypothesis. Although seemingly to be quite ambitious, the new de-sulphur policy will only bring very slight economic growth lose. The most part of pollution reduction will be realized by the substitution between polluting and less or non-polluting energies. The combination of the trade liberalization and pollution control policies seems to give China more flexibility in adapting her economy to the new de-sulphurs objective. Considering different aspect together, the total economy loss due to new de-sulphur policy will be limited to only –0.18% under the presence of trade liberalization.Externality., Energy substitution, Industrial SO2 pollution, Trade, CGE
A review on the role of green vegetation in improving urban environmental quality
The exacerbation of climate change impacts within metropolitan areas is a well-documented phenomenon, often leading to severe consequences that pose significant risks to human populations. The impact of urban vegetation and planting design on these factors can be observed. However, it is worth mentioning that while there is an extensive body of literature on the consequences of climate change, there is a relatively small number of studies specifically focused on examining the role of vegetation as a mitigating factor in urban environments. This review paper aims to critically examine existing studies pertaining to the role of urban vegetation in mitigating the detrimental effects of the urban environment. The objective is to offer practical recommendations that can be implemented by city planners. By conducting a comprehensive examination of the literature available in Scopus, Web of Science, and Google Scholar, employing specific keywords pertaining to urban vegetation and climate change, we have identified five prominent concerns pertaining to the urban environment. These concerns encompass particulate matter, gaseous pollution, noise pollution, water runoff, and the urban heat island effect. The present analysis highlights that the impact of urban vegetation on the negative consequences of climate change cannot be unequivocally classified as either positive or negative. This is due to the fact that the influence of urban greenery is intricately connected to factors such as the arrangement, makeup, and dispersion of vegetation, as well as the specific management criteria employed. Hence, this research has the potential to enhance comprehension of the multifaceted nature of urban green spaces and establish a solid groundwork for subsequent investigations
