Are there limits to growth? The need for a transition to a solar-based economy

The idea of limits to growth has, understandably, achieved notoriety since the days of Malthus and, more recently, the Club of Rome. However, there must be some limits to the ability of the earth to sustain a growing population. Fortunately, population models suggest that the world's population will probably level out at about two to three times the present numbers over the next hundred years. The question is whether the earth's resources are sufficient to sustain that population at a high standard of living for all. In this the key issue is energy. It is clear that present trends in energy consumption, especially oil, cannot be sustained much longer. Regardless of this, however, prudence demands a drastic reduction in fossil fuel consumption, in view of the possibility of global warming. It can be shown that, combined with greatly improved energy efficiency, a transition to a solar (renewable) energy based economy, capable of sustaining the anticipated growth in the world economy, is possible, but the constraints are extremely tight .     

Adding public value: The limits of corporate responsibility

It is suggested that natural resource companies undertaking large-scale projects may be expanding the scope of corporate social responsibility by working to enhance the capabilities of the public sector. Naturally companies are concerned to protect their investments, and to ensure their viability. They will therefore invest in necessary infrastructure and facilities of all types, where those are lacking. Such investment often provides benefits to the wider community, but with a few exceptions these are normally incidental byproducts rather than inherent objectives. The motivation for companies to provide resources of all types in order to enhance the capabilities of the public sector to provide public services is usually an expectation is that the tangible benefits will exceed the costs, rather than altruism. One driving force is to secure and maintain a company's social licence to operate. More recently competition from Chinese firms is prompting private sector companies to offer comparable investments in infrastructure. It is unclear whether investment in public sector capabilities is cyclical and liable to cutbacks when market conditions deteriorate. Changing market conditions affect not just corporate willingness to spend but also host countries’ bargaining strengths. In boom periods host countries will be more able to secure straightforward financial benefits through higher tax receipts than when markets are weak. Beyond the specific needs of individual projects corporate policies are strongly influenced by the beliefs of senior managers. External pressures both from international institutions and from NGOs also drive corporate behaviour. The success of investment in public sector capabilities relies in the end on the responses of host countries, and on how closely the objectives and interests of the government are aligned with maximising the nation's long term wealth and welfare. Where they are not corporate resources may be frittered away. There are also questions over the legitimacy of corporate investments, especially by foreign-owned companies. They have a right to offer advice and protect their legitimate interests, but these may not always coincide with those of their host countries. There is a range of questions about the appropriate role of companies, which lead on to feasible and effective ways of improving weak governance.     

The limits of technological optimism

Summary Technological optimism is the doctrine that a growing number of technological improvements in such areas as food production, environmental quality and energy will sustain life as human population soars. It evolved as a response to the Malthusian study The Limits to Growth (The Club of Rome, 1972). Like population biologist Paul Ehrlich, Professor James Krier of the University of Michigan Law School believes that the technological optimists may be wrong. Krier describes how the marginal costs of pollution control increasingly rise. He faults biologist Barry Commoner for neglecting population growth as the cause of pollution and positing the postwar technological transition as its cause. He argues that population growth forced this transition as science searched for substitutes for dwindling resources. Krier criticises as an article of faith the technological optimists' belief that S-curve patterns of technological advance will always arrive in response to the J-curve of exponential population growth. He thinks that the technological optimists may be deluding humanity by predicting the continual emergence of technological breakthroughs at ever-increasing rates. He favours growth policies that would allow humanity to ease into a steady state of resource use and minimise the maximum cost, which would be a global crash after technological innovation fails. Krier laments that modern technolgy can worsen pollution and invites problems of latency, irreversibility, zero-infinity risk and remoteness. He thinks that approapriate technologies which have failed economically may fail politically because the political process has been captured by opposing interests. Krier urges that the population crisis should be adressed insteadAndrew D. Basiago is a graduate of UCLA and Northwestern School of Law's environmental law programme.

Conservation at landscape level: A strategy for survival: The role of research

Summary The objectives, appropriate strategies, the state of conservation in South Africa, and the contributed research which is needed, are evaluated. It is suggested that the ultimate objectives of conservation are to maintain the ecosystem to support people and to achieve economic advantages. These can only be obtained by providing for the greatest possible diversity of life on Earth. An appropriate conservation strategy can be based on a balanced combination of five types of conservation opportunities. These opportunities are: (i) formal conservation in reserves, (ii) promotion of land use change for conservation, (iii) law enforcement, (iv) national resource utilisation planning, and (v) the development of a national land ethic. Adjustment of the opportunity combination to address changing threast must be an ongoing exercise. Conservation strategies need to be based on sound conceptual models of ecosystem structure and function, as well as human needs and aspirations. The main goals of the conservation ecologist are the development, testing and validation of conceptual models of ecosystems.Mr Zak Le Roux is employed in the Scientific Services Section of the Ecosystem Conservation Department of the Natal Parks Board. He possesses a BSc in Forestry and Nature Conservation from the University of Stellenbosch, and is currently undertaking research in Plant Ecology at the University of Natal. A tenth generation South African, his work focuses on vegetation dynamics of semi-arid savanna landscapes and general conservation in Zululand. In particular, this involves the integration of wildlife with agriculture, and the development of more appropriate land uses in the areas surrounding the parks.     

Landscape planning: A method applied to a growth management example

This article is the first in a series of three. These articles were prepared to document the growth management process undertaken in Teller County, Colorado, USA. In this article, an 11-step method for landscape planning is proposed. In step 1, an issue, or set of related issues, is identified as posing a problem and/or opportunity to people and/or the environment. In step 2, a goal, or several goals, is established to address the problem or opportunity. In steps 3 and 4, inventories and analyses of biophysical and sociocultural processes are conducted, first at the regional level and then at the local level. Step 5 involves detailed studies (such as suitability analyses) that link the inventory and analysis information to the problems or opportunities and goals. Detailed studies link regional and local information to specific sites. Thus, this method involves a regional-local-specific site hierarchy. In step 6, concepts are developed that lead to a landscape plan in step 7. During step 8, the plan is explained through a systematic educational and citizen involvement effort to the affected public. In step 9, detailed designs are developed that again are explained to the specific individuals who will be impacted by the designs. It is in step 10 when the plan and designs are implemented. Step 11 involves the administration of the plan. The method is illustrated through an example of growth management planning for Teller County and the city of Woodland Park, Colorado.

The adaptation and control model of user needs: A new direction for housing research

The Canadian context of user needs research in housing is briefly outlined. The Needs and Preferences research model is described and three basic assumptions are outlined. Challenges to the three assumptions are identified, and two empirical studies are invoked to substantiate the critique. An Adaptation and Control Model of user needs research in housing is presented as a possible alternative model that has implications for methodological change and refinement. The opinion is advanced that this model potentially remedies some of the shortcomings of the Needs and Preferences Model.     

Management knowledge through wildlife research: A perspective

Wildlife management is a large, complex, decisionoriented science. Information from research is needed to improve the decisions made by managers. The scope of the research needed to inform typical decisions far exceeds even the most optimistic assumptions about the available funds, time, or human resources. An argument is made that while changes within the current management structures are unlikely, continuing classical experimental research alone will not meet the timely needs of the field or of citizens dependent on wildlife resources. Continuing in such a no-win game seems to be a misallocation of time and funds. Significant changes are called for and suggestions for such changes are made: discussions with people in other broadly defined fields with a similar problem, new sampling strategies, increased use of computer models, use of geobased information systems, use of game theory, nonspecies research grouping, new funding structures, and sharing of facilities and of teams of specialists.     

Community-based participatory research: Changing scientific practice from research on communities to research with and for communities

This paper examines community based participatory research from the viewpoint of the author, a doctoral student seeking to understand the concepts and framework of successful participatory research as a complement to traditional discipline driven research. Challenges and progress of CBPR within academia are examined, including acceptance, funding, training, and development of equal partnerships between university researchers and communities. Case studies (Latowsky, 2003; Ammerman et al., 2003; Stratford et al., 2003) focus on CBPR in different environmental justice communities, revealing the need to foster trust and communication in order to execute culturally competent and relevant research projects.     

Ecological indicators of global climate change: A research framework

Large-scale environmental research efforts are conducted under frameworks that provide a common basis for evaluating research in many diverse fields. Such frameworks should be subjected to critical review to determine if they meet crucial expectations. In the case of the US Global Change Research Program, we perceive that most research follows a framework that we define as the predictive model framework. We believe this framework is insufficient for resolving the unprecedented predicaments posed by global change. We recommend a complementary framework, the system response framework, which directs research toward useful indicators of change rather than precise predictions. We further argue that, even if research is complementary and effective under the two frameworks, conclusive results prior to decisions should not be expected. The burden of proof must itself be a continuing topic of open discourse and inquiry.     

Mining development,income growth and poverty alleviation: A multiplier decomposition technique applied to China

Mining has grown rapidly and is expected to continue to develop solidly in the future with the economic development in China. Based on this trend, how an increase in the outputs of mining sectors affects household income and poverty alleviation is an issue worthy of study. A multiplier decomposition method within a social accounting matrix (SAM) framework shows the linkages through which a mining sector's output contributes to household income growth and poverty alleviation. The decomposition applied to China reveals that mining development has more significantly positive impacts on the high and middle income household than low income household. Moreover, the decomposition incorporated with the Foster, Greer and Thoerbecke (FGT) poverty measure shows that the ‘coal’ sector contributes most to poverty alleviation and the low income household group, which has the biggest poverty rate, is the smallest beneficiary from the mining development. Thus, the policy implication is proposed that the government should give appropriate adjustment on the distribution of income between rich and poor households and help the unskilled human capital from the household group at a low income level to handle advanced technology of mining through education and training to reduce poverty more effectively.     

The use (and abuse) of the new environmental paradigm scale over the last 30 years: A meta-analysis

This paper reports a meta-analysis of studies using the New Environmental Paradigm (NEP) Scale over the last 30 years. A review of 69 studies from 36 countries (including 58,279 participants from 139 samples) shows that there is considerable variation in the way the NEP Scale is used, particularly with regards to the number of items used and the number of points on the Likert scale employed. Results from weighted regression analyses reveals that variations in sample type and scale length have a significant effect on NEP scores. In particular, environmentalist and white-collar samples scored significantly higher on the NEP Scale than nationally or regionally representative samples, while blue-collar samples scored significantly lower; and participants scored higher on 6-item versions of the scale than on the revised 15-item version, and lower on versions of the scale containing 5, 7, 8 or 10 items. Implications of this research for the comparability of previous studies using the NEP Scale are discussed and guidelines for future research are presented.     

Designing for interaction in research environments: A case study

Graduate researchers are an essential part of higher education (HE) in terms of its contribution to knowledge and the wider economy, but how the work environment influences behaviour and productivity in this work domain is poorly understood. Nevertheless, building programmes continue with a detectable trend towards more open office designs. Beyond issues of cost-efficiency, this reflects a popular belief in the significance of face-to-face interaction to research productivity. Using a combination of subjective and quantitative methods, this case study investigates the validity of this claim and how a redesigned environment impacts upon work practices and collaboration within a community of researchers. Although the new environment was judged favourably by occupants and managers, analysis suggests a less positive behavioural response. Contrary to expectation, we conclude that providing open plan environments is not sufficient to produce more collaborative practices in HE. We argue that this would require changes in the organisational structure, the reward structure for individual and team-driven tasks, and the firm policing of the management of change.     

Allocating anthropogenic pollutant emissions over space: application to ozone pollution management

An inventory of volatile organic compound (VOC) and nitrogen oxides (NOx) emissions is an important tool for the management of ground-level ozone pollution. This paper has two broad aims: it illustrates the potential of a geographic information system (GIS) for enhancing an existing spatially-aggregated, anthropogenic emissions inventory (EI) for Tucson, AZ, and it discusses the ozone-specific management implications of the resulting spatially-disaggregated EI. The main GIS-related methods include calculating emissions for specific features, spatially disaggregating region-wide emissions totals for area sources, and adding emissions from various point sources. In addition, temporal allocation factors enable the addition of a multi-temporal component to the inventory. The resulting inventory reveals that on-road motor vehicles account for approximately 50% of VOC and NOx emissions annually. On-road motor vehicles and residential wood combustion are the largest VOC sources in the summer and winter months, respectively. On-road motor vehicles are always the largest NOx sources. The most noticeable weekday vs. weekend VOC emissions differences are triggered by increased residential wood combustion and increased lawn and garden equipment use on weekends. Concerning the EI's uncertainties and errors, on-road mobile, construction equipment, and lawn and garden equipment are identified as sources in the most need of further investigation. Overall, the EIs spatial component increases its utility as a management tool, which might involve visualization-driven analyses and air quality modeling.     

From research to action: Now we have to move on CCS communication

With rising levels of atmospheric carbon dioxide (CO₂), a portfolio of mitigation options is deemed essential as we transition to a low carbon economy. Carbon dioxide capture and storage (CCS) is one technology that has the potential to mitigate large amounts of CO₂ and governments around the world, along with industry and researchers working in the technology space, are excited by this. However, the technology still remains relatively unknown in the minds of most lay citizens and is therefore less well accepted than more traditional forms of power generation. This paper reviews a number of CCS communication research activities that have been undertaken internationally since 2002 and synthesizes them into a logical roadmap of activities. The paper also examines the common strengths and weaknesses of the research activities and makes a number of suggestions for industry representatives and policy makers. The paper also outlines a way to segment stakeholder groups for all communication activities into four target audiences including: influential others; community; education and project specific activities.     

“Conflict over Risks in Food Production: A Challenge for Democracy”

When it comes to conflict over risk management priorities in food production, a number of observers, including myself, have called for some sort of public deliberation as a means of resolving the moral disagreements underlying such conflicts. This paper asks how, precisely, such deliberation might be facilitated. It is shown that representative democracy and the liberal regulation that most Western democracies adhere to place important constraints on public deliberation. The challenge is to find forums for public deliberation that can operate within these constraints while still making a constructive contribution.     

The Struggle over Functional Foods: Justice and the Social Meaning of Functional Foods

The social and scientific debate overfunctional foods has two focal points: one isthe issue of the reliability andtrustworthiness of the claims connected withfunctional foods. You don't have to be asuspicious person to be skeptical vis-à-visthe rather exorbitant claims of most functionalfoods. They promise prevention against allkinds of illnesses and enhancement ofachievements like memory and vision, withouthaving been tested adequately. The second issueis the issue of the socio-cultural dimension offunctional foods and their so calleddetrimental effect on the social and normativemeanings of food, with possibly the effect thatfood in general will be treated like amedicine, with radical individualizing effects.Finally, individuals would only be allowed toeat what their gene-profile prescribes them. Inthis paper, it is argued that food is anon-neutral public good that contributesinherently to the identity of vulnerableindividuals. It should be treated in anon-neutral, but impartial way. Therefore,politics need to intervene in food markets froma justice and ethical point of view with twoaims in mind. The first aim (as an implicationof justice considerations) should be toestablish safety conditions, and to identifyand monitor food safety standards in anobjective and impartial way. Preventive medicalclaims of foods should be allowed on the basisof appropriate and objective testing methods.The second aim (as an implication of ethicalconsiderations) should be to shape conditionsfor a cohabitation of various food styles,including that of functional foods. Moreover,the cultural and symbolic meaning of food in apluralistic society requires that the differentfood styles find some modus of living andinteracting together. As long as functionalfoods comply with safety standards and respectother food styles, they should be allowed onthe market, just like any other food product.     

Issues in extractive resource taxation: A review of research methods and models

This paper provides a conceptual overview of economists′ attempts to learn about the effects of taxes on extractive resources. The emphasis is on research methods and techniques, with no attempt to provide a comprehensive tabulation of previous empirical results or policy conclusions regarding preferred tax instruments or systems. We argue, in fact, that the nature of such conclusions largely depends on, and is limited by, the researcher′s choice of modeling framework. Many alternative frameworks and approaches have been developed in the literature. Our goal is to describe the differences among them and to note their strengths and limitations.
