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.

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.

This article explores the special features of the rural–urban transformation in East Asia in the last 30 years within the
broader context of the development strategies of Asian governments. Despite an ongoing commitment to the rhetoric of concern
with rural development, food security and the alleviation of rural poverty, these policies have emphasised the important role
of urbanisation as the prime process influencing economic growth. This is supported by the economic argument that the economies
of scale, the creation of mass urban markets and the higher productivity that occur in urban places make them crucial to development.
This paper argues that this approach creates a false dichotomy between rural and urban areas, whereas development should aim
to increase the linkages between rural and urban areas aimed at producing societal transformations rather than separate rural
and urban transitions. The paper then explores the empirical evidence of rural–urban transitions in East Asia with a more
detailed case study of China, which is considered to be a crucial example because of the size of its population, the special
conditions of market socialism and its institutional capacity to manage the rural–urban transformation. The final section
focusses on the importance of developing spatial sensitivity to the management of the rural–urban transformation in the 21st
century. Old divisions between rural and urban sectors must be replaced by planning that integrates urban and rural activities
so that they adopt sustainable management strategies which utilise concepts of eco-systems in which rural and urban activities
are linked, so as to create sustainable urban regions, cities and societies.

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.

This study explores the interlinkages among population, environment and poverty and presents empirical evidence in a developing
country like Pakistan. It gives alternative views on population environment linkages. It explains poverty trap, market based
harmony, and dual effect of poverty on the basis of a link between population growth and natural resource degradation. In
addition, the paper also highlights social and political instability through population-poverty-environment spiral. It also
presents empirical evidence on population-environment-poverty nexus in Pakistan. It also compares environmental sustainability
index and human development index for selected Asian countries. The paper also gives scores for different components of environmental
sustainability index for Pakistan and compares these with India. The paper concludes that the causal relationship between
poverty and environment works in both directions, often through changes in GDP and population. Population stress does not
have any significant direct effect on all aspects of environmental status in Pakistan.

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.

The Central Niger Delta is made up of a network of rivers and creeks that constitute the inland surface waters. These surface
waters have historically influenced settlement patterns and are of diverse use to residents of the Central Niger Delta. Surface
water like many ecological system are complex, whose complexity has been associated with seasonal variability. Traditional
knowledge (TK), traditional ecological knowledge (TEK) and the traditional eco-livelihood knowledge (TELK) of residents of
four rural communities in the Central Niger Delta have been explored in developing a river use profile of rural communities
of the Central Niger Delta. A questionnaire survey has been carried out in four communities, two each from the Otuoke and
Kolo Creeks. The result shows that river use varies across seasons and affected by: physico-chemical water quality and characteristics
of surface water; the hydrological characteristics; the biological/ecological characteristics; cultural use and demand; need
for development projects; and access to this vital resource. Fishing constitute one of the major livelihood source in the
Central Niger Delta and the TELK of fishers in the sample communities have specifically been explored to understanding fishing
patterns across seasons. The five seasons identified from this study are: flood season; flood recession season; dry season;
early rainy season; and rainy season. Therefore, the thesis of this paper is that there is the need to balance the current
usage of surface water in the developing world such as the Central Niger Delta with the demand for development as well as
future use if development is to meet the criteria for equitable development. The river use profile could be a promising tool
in planning for equitable development.

This paper is a response to a recent special issue of Regional Environmental Change, “Quantifying vulnerability to drought from different disciplinary perspectives” (vol. 8, number 4, 2008). In this paper,
we examine some of the challenges facing efforts to understand vulnerability to drought through quantification as they are
manifest in some of the articles in this special issue.

Soil erosion is a major environmental problem and threat to rural development in Kenya. Numerous attempts to address the problem
have apparently had little success. There are however some districts that have been very successful, notably Machakos. In
this study we search for the factors that determine successful development in soil conservation such as social capital, human
capital and market integration. One of our main results is that social capital measures are significant determinants of investment
in soil conservation. A better understanding of the relevant mechanisms is essential for developing policies targeting improvement
in natural resource management.

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.

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.

Working toward sustainable community is a complex task for communities especially given the ambiguous nature of implementing
the concept of sustainable development. However, by working to understand the nature of community capital, administrators
can begin to move beyond bottom line thinking toward a more comprehensive and collective view of community. This paper presents
a theoretical framework that helps municipal decision makers begin collecting information they need to help them build sustainable
and resilient communities.

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.

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.

Application of fuzzy models to assess susceptibility to droughts from a socio-economic perspective 总被引:1,自引:1,他引:0

By combining the concepts of environmental stress, state susceptibility and environmental crisis, “Security Diagram” (SD)
provides a quantitative approach to assessing environmental change and human security. The SD is a tool that clearly presents
in a diagram the security situation of a population or region affected by a particular environmental crisis. Its underlying
concept emphasises that the higher the level of environmental stress and socio-economic susceptibility, the higher the probability
of the occurrence of crisis. Focusing on drought, this study analyses the susceptibility of case study regions in India, Portugal,
and Russia from a socio-economic perspective. A conceptual framework of socio-economic susceptibility is developed based on
the economic development theories of modernisation and dependency. Fuzzy set theory is used to generate susceptibility indices
from a range of national and sub-national indicators, including financial resources, agricultural dependency and infrastructure
development (for economic susceptibility), and health condition, educational attainment and gender inequality (for social
susceptibility). Results indicate that socio-economic susceptibility over the period 1980–1995 was highest in India, followed
by Russia and (since 1989) lowest in Portugal. Globalisation is likely to contribute to changes in the level of socio-economic
susceptibility over time. Moreover, specific social and economic structures unique in each country (e.g., the role of women
in society in India, the socialist legacy in Russia) may explain differences in susceptibility between the case study regions.

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.

In this study we perform an ecological analysis of the resources use in the diet of the ribeirinho populations of the Barcelos municipality, Rio Negro, Amazonas, Brazil. Data on food composition, seasonality, and origin
took place during three field trips between 1999 and 2000. Data were gathered based on structured interviews and observations
from a total of 320 meals of 114 randomly selected families and 164 fishing trips. The staple food of the studied populations
is based on fish and manioc, although the food niche amplitude can vary according to the factors such as the access to imported
food items, resources seasonality, and socio-economic conditions. The migration to urban centers along with the changes in
subsistence activities (reduction of small-scale agriculture and specialization in commercial fishing) may result in changes
in the food habits of ribeirinho populations from Rio Negro.

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.
