Using survey-based data approach for modeling the demand for environmental goods/resources, this study estimates income and
price elasticities of demand for improved environmental quality of two National Parks in Northern Pakistan. The study uses
data from two studies. The estimates indicate that improved environmental quality effects can be described as a luxury and
an ordinary and price elastic service. Confidence intervals show however that the classification as a luxury is not statistically
significant. Income elasticities of willingness to pay are estimated for a broad range of environmental services. The study
finds that income and willingness to pay vary directly and significantly. The elasticity estimates, in general, are greater
than zero, but less than unity. The study concludes that environmental improvements are more beneficial to low-income groups
than for high-income groups.

The contamination of groundwater in Bangladesh by arsenic is a widespread and serious environmental problem, affecting mainly
the rural population who rely extensively on groundwater for drinking and cooking. The study conducted survey work in a few
affected villages of the Northwest region in Bangladesh. The household survey gathered information on the respondents (affected
by arsenic) water usage and sources, knowledge of the arsenic problem, changes in the source of water for drinking and cooking,
arsenic mitigation technologies and socio-economic information on the households. The survey work shows that percentage of
male patient is higher than female patient among the same level of household income in each study villages. Prevalence of
arsenicosis is more among poorer sections and it is directly related to the poverty situation of the community. People know
more about the health problems caused by arsenicosis but lack knowledge about mitigation aspects. In one of the study areas,
every year an extra 4% tubewell is getting contaminated by arsenic. Arsenic contamination in groundwater also affects the
environment and the ecology negatively. The NGOs have been found contributing to a knowledge creation process in the village
community as the villagers are showing marked behavioral changes in water-use practice.

There is a general contention among scholars that first, wheat–paddy cropping pattern is largely responsible for declining
ground water table in Punjab and secondly, that the wheat–paddy cropping system is becoming unsustainable over time as the
yield levels of these two major crops are stagnating. However, the existing evidences do not throw adequate insight into the
stage of groundwater depletion during which the wheat–paddy cycle becomes unsustainable. The paper strengthens the existing
empirical base of sustainability status of this cropping cycle in Punjab. A comparison of irrigation systems in terms of both
trends in yield and stability for wheat and paddy has been attempted to arrive at a holistic appraisal of sustainability aspects
of crop specialization in Punjab. It is observed that the canal dependent irrigation system has performed better as compared
to the overexploited groundwater irrigation system in terms of most of the parameters used in the study.

The objective of the paper is to measure environmental degradation on the basis of some selected indicators by the application
of a simple multivariate technique known as Principal Component Analysis. For this purpose the study considered six variables,
namely, GDP per capita, fuel consumption, total fertility rate, water supply, sanitation, and electricity. However, because
of unavailability of data, the variables such as technology relating to environment, waste disposal, air pollution, women/gender
issues relating to environment, corruption, democracy etc. could not be considered. The results show that principal components
explain about 62% of the variations in the level of environmental degradation. The variables like GDP per capita, fuel consumption,
water supply and electricity played a major role in classifying the countries in terms of environmental degradation compared
to the variables, sanitation and total fertility rate. The findings show that countries which have high GDP per capita, low
fuel consumption, higher percentage of people having access to water supply and sanitation as well as electricity ranked higher
in terms of environmental quality despite high fertility rate as shown by the spectacular example of Saudi Arabia. By contrast,
those countries which have low percentage of population having access to safe water and sanitation as well as electricity,
high fuel consumption and high fertility were ranked lower in terms of environmental quality despite high per capita income,
as shown by the example of Angola which is placed in lowest position among the 51 selected countries. The results also show
that correlation between poverty and environmental degradation is particularly acute in African countries where high population
growth is acting as an exacerbating factor. The study concluded that high fertility has much impact on environmental degradation
in case of poorer countries than in case of rich countries.

Sustainable engineering is a conceptual and practical challenge to all engineering disciplines. Although the profession has
experience with environmental dimensions of engineering activities that in some cases are quite deep, extending the existing
body of practice to sustainable engineering by including social and cultural domains is a significant and non-trivial challenge.
Nonetheless, progress is being made, as a recent study undertaken by the Center for Sustainable Engineering in the United
States demonstrates.

Terrascope is a freshman learning community at the Massachusetts Institute of Technology (MIT) in which teams of students
work to find solutions to large ‘unsolvable’ problems and to communicate about those problems with a wide variety of audiences
in multiple formats. The program strongly promotes students’ autonomy in focusing and structuring their work, and student
projects culminate in public presentations, both to general audiences and to panels of technical specialists. Students who
have completed the program tend to show strong engagement with environmental and sustainability issues, as well as the skills
and experience to work intensively on such issues within multidisciplinary teams. Here, we present the program as a case study,
with some discussion of the factors that are key to its operation.

Educational initiative of Osaka University in sustainability science: mobilizing science and technology towards sustainability 总被引:1,自引:1,他引:0

One of the most important and yet difficult challenges that modern societies face is how to mobilize science and technology
(S&T) to minimize the impact of human activities on the Earth’s life support systems. As the establishment of inter-disciplinary
education programs is necessary to design a unified vision towards understanding the complexity of human nature, the Research
Institute for Sustainability Science (RISS) launched a new program on sustainability science in April 2008. The program expects
to address the issue of how to use knowledge more effectively to understand the dynamic interactions between nature and human
society. This paper first offers an overview of international and Japanese initiatives on sustainability education in which
we highlight the uniqueness of the attempt by the Integrated Research System for Sustainability Science (IR3S). The paper
then introduces the RISS program for sustainability science, addressing the principles and curriculum design of the program.
The paper discusses the main problems and constraints faced when developing the program, such as institutional barriers in
building a curriculum and obtaining cooperation from faculty. To challenge these barriers and limitations, the RISS uses the
program as a platform to disseminate the idea of sustainability science across the university. This attempt helps us to obtain
the continuing cooperation necessary to improve and maintain the program.

This paper aims at assessing the extent to which the ecological footprint indicator (EF) can be regarded as an exhibit allowing
an intergenerational trial about the use of natural resources. For that purpose, we examine various criticisms questioning
the relevancy of EF measures for the study of environmental justice between generations. We explore the difficulties raised
by the physical—and highly aggregated—nature of EF measures, as well as problems related to the number, the possible non-existence,
and the tastes of future generations. The extent to which postulates on nature’s regeneration and technological progress affect
the significance of EF studies is also discussed. It is concluded that those criticisms, by identifying various weaknesses
of EF measures for the study of intergenerational justice, point to several crucial refinements of existing EF-based analyses.

The policy sciences, in offering the most comprehensive approach to policy analysis and the sociopolitical processes that
shape policy outcomes, is particularly appropriate for guiding the analysis required to promote sustainability. This article
presents the main components of the policy sciences framework and demonstrates its potency in the crucial task of deepening
the problem definitions required to select and enact policies to promote sustainability. As such, it provides background for
the policy sciences articles of this special feature.

This paper examines the environment-income relationship in the context of the Environmental Kuznets Curve (EKC), and explores
the possible role that factors like governance, political institutions, socioeconomic conditions, and education play in influencing
this relationship. The results suggest that the EKC exists for carbon dioxide emissions for cross-country data over the period
1984–2002. However, there is nothing automatic about this relationship; policies designed to protect the environment may be
responsible for this phenomenon. Two other significant findings are: one, countries with better quality of governance, stronger
political institutions, better socioeconomic conditions and greater investment in education have lower emissions; and two,
only around 15% of the countries in the dataset have reached income levels high enough to be associated with an unambiguous
decline in emissions. The implications of these results are discussed within the context of the international environmental
policy arena and the Kyoto Protocol. One of the main objectives of this paper is to bridge the gap between studies conducted
on the EKC and developments in the international environmental policy arena. As a final note this paper emphasizes that one
needs to connect the body of knowledge on the EKC hypothesis to the international environmental policy arena, despite the
apparent difficulty of doing so. One hopes that future studies will further build on this line of thought.

Commonly occurring natural events become natural disasters when they affect the population through death and injury, and/or
through the destruction of natural and physical capital on which people rely for their livelihood and quality of life. Climate
change plays a role in that it tends to increase the frequency and intensity of weather-related natural disasters. Additionally,
climate change may put people at risk by influencing access to water, coastal flooding, disease and hunger, and leaving them
with a more degraded environment, leading, in turn, to increased vulnerability. The purpose of this paper is to present a
review and synthesis of the literature and case studies addressing differential impacts of climate change-related natural
disasters on a society and its economy. Developed and developing countries show different vulnerabilities to natural disasters.
Even within countries, impacts vary significantly across population and economic sectors. When losses from natural disasters
are large, their cumulative effect can have notable macroeconomic impacts, which feed back to further pronounce existing income
inequalities and lower income levels. Impacts tend to be most pronounced for women, the young and elderly, and people of ethnic
or racial minorities.

Soil erosion in many parts of the developing world poses a threat to rural livelihoods, to the sustainbility of the agricultural
sector, and to the environment. Most erosion prediction models are mechanistic and unsuited to quantify the severity of soil
erosion in a data-limited developing world context. The model developed in this paper for Negros Island, in the central Philippines,
is based on the Revised Universal Soil Loss Equation, but contains important innovations such as the movement of eroded soil
over the landscape, simulating deposition on lower slopes and in waterways. It also includes a term describing farmer strategies
to reduce soil erosion, which are typically ignored in erosion prediction models. A two-sample t-test found that model-predicted sediment loading values were not significantly different from field-measured sediment loading
values when corrected for watershed size (P = 0.857). The model predicts an annual loss of 2.7 million cubic meters of sediment to waterways such that by 2050 more than
416,000 ha of agricultural land will be rendered unproductive due to erosion. Farmer behavior conserves soil, but on the steepest
slopes soil conservation practices are not adequate to prevent erosion. Of two proposed strategies to control soil erosion
in the rural Philippines, the model suggests that a complete switch to tree crops would conserve more soil than universal
terrace adoption. However, even under these conservation scenarios, erosion threatens the areal extent of upland agriculture
on Negros, and hence the sustainability of the island’s food supply.

The objectives of this study are twofold. First it aims to establish empirical grounds for pricing the services of a new environmental
management initiative in Enugu state, Nigeria. A joint initiative of the UK Department for International Development (DfID),
Enugu State Environmental Protection Agency (ENSEPA) and the State and Local Government Programme (SLGP). The second is to
test the empirical performance of a new approach to the contingent valuation method (CVM) i.e., the Stochastic Payment Card
(SPC) design proposed by Wang (Contingent valuation of environmental resources: A stochastic perspective, 1997a, Journal of Environmental Economics & Management, 32:219–232, 1997b). The SPC design unlike many of the conventional CVM elicitation formats, takes into account the stochastic nature of individuals’
valuation decisions. The data for the analysis were obtained from a random sample survey of a district in Enugu metropolis.
The results show that, on average, households in this city are willing to pay (WTP) 215 Naira ($1.6) monthly as against 200 Naira
($1.5) currently charged for the service by ENSEPA. Analysis of individual’s valuation distribution function indicates that
this amount is positively and significantly related to the gender of the respondent, household income and the respondent’s
perception of environmental quality.

Most environmental professionals and decision-makers, and certainly the public at large, hold the view that the integrity
of earth’s natural environment will be conserved for posterity and sustainable development achieved if all the nations rigorously
enforced their environmental and emission standards. It is argued in this paper that this view, sincerely held by many as
an “axiomatic truth,” is mistaken and misplaced. This is because as a biogeochemical entity the Earth has limited self-regenerative
capacity (SRC) to cope with anthropogenic pollution, and all kinds of environmental problems ensue when that limit is exceeded.
Indeed, mounting environmental problems now occurring on all fronts amply testify to the fact that the limit has already been
exceeded. They also provide necessary and sufficient proof that environmental and emission standards have been woefully inadequate
for protecting earth’s natural environment and life-support systems. It is argued that true global environmental sustainability
will be achieved, paving the way to true global sustainable development, if and only if global environmental and emission
standards are set so that global anthropogenic pollution does not exceed the limit of earth’s natural SRC to cope with such
pollution. These and related issues are discussed in this paper. A simple mathematical model using basic mathematics is also
presented to explain how the phenomenon of “positive feedback” works in some of the environmental problems to exacerbate environmental
degradation and progressively to erode nature’s SRC.

The issue of the sustainable development of rural economies in England has recently received considerable attention. This
is because many of the poorest areas in the country are rural, often of high environmental quality, but suffering from high
unemployment and a lack of services and facilities. The rapid decline in agricultural incomes and in-migration of affluent
urban workers since 1990 has exacerbated economic inequality in such areas. A number of factors have the potential to drive
rural development and this paper applies, and considers, the feasibility of a method from the USA for combining economic and
environmental variables in a regional growth model to examine the hypothesis that environmental quality is an important determinant
of sustainable rural development in England. The model output suggests that, although environmental quality does play a role
in sustainable rural development in England there are other, more important, factors driving development. These include business
and communications infra-structure, the degree and opportunities for commuting and underlying employment prospects. The robustness
and limitations of the method for combining economic and environmental variables is discussed in relation to the spatial interrelatedness
of Local Authority Districts in England, and conclusions are drawn about areas for refinement and improvement of the method.

Culture as trigger for sustainability transition in the water domain: the case of the Spanish water policy and the Ebro river basin 总被引:2,自引:2,他引:0
There is a mounting body of literature dealing generally with the dynamics of transitions of human systems towards sustainability
and specifically with the different stages and processes of transitions. However, the question of why transition processes
occur in the first place remains largely unexplained. This paper explores the concept of transition triggers, such as culture
or material resource scarcity, and provides a theoretical framework to explain the emergence of a transition and its relation
to recent developments in Spanish water policy. We adapt the general framework provided by current transition theory and gather
empirical evidence and insights from processes occurring within the Spanish policy context and the Ebro river basin in particular.
Our results show that the sole existence of biophysical limits to water use or development cannot explain the start of a possible
sustainability transition in this domain in Spain. Changes in the existing water policies in the direction of sustainability
were not ignited by people directly affected by water scarcities but by a coalition of sensitive agents, mostly from academia,
NGOs and local constituencies, who managed to articulate new identities, integrate multiple sources of policy relevant knowledge,
and develop new values under the umbrella of the new water culture movement.

The East Asian economy has been growing fast in recent years, and environmental stresses are building up rapidly. Transboundary air pollution, water shortages, drinking water contamination, freshwater and marine pollution, deforestation, climatic disasters, and other environmental problems are becoming serious threats to the well-being of people in this densely populated region. The ESI (environmental sustainability index) reported by the World Economic Forum in 2005 is a good indicator of the environmental status of the region; most East Asian countries ranked at the bottom. East Asia is not moving toward a sustainable society, and the environment will not sustain the current rate of economic development for long. The traditional culture of East Asia used to be sustainable, so we can learn much from our traditions. Land use should be planned from an ecological point of view so as to best preserve the land’s productivity and stability. There should be definite goals as to where and how much to preserve the three important ecological bases: forests, coastal wetlands and agricultural farms. The forest is the base for the terrestrial ecosystem, including flood control, water resources, and climate; the coastal wetland is the base for the marine ecosystem; farmland is the base for producing food. Within these defined goals, limits should be set on how much land can be utilized for activities like urban development, manufacturing, and recreation. Limits on the pollution load resulting from such activities should be set so as not to irreversibly damage the environment. Economic development should be planned to allow the use of energy and resources only after satisfying these constraints.
