According to Van Den Bergh,[27] resilience can be considered as a global, structural stability concept, based on the idea that multiple, locally stable ecosystems can exist. This would imply that the various kinds of capital are more or less substitutable, at least within the boundaries of current levels of economic activity and resource endowment. Strong sustainability assumes that the economic and environmental capital is complementary, but not interchangeable. 1991. Weak sustainability maintains that economic and social issues must be integrated in sustainability discussions and allows one form of capital (human, natural, social, constructed, cultural) to substitute for another. Except where otherwise indicated, Everything.Explained.Today is © Copyright 2009-2020, A B Cryer, All Rights Reserved. A key example of this is the World Bank, who now regularly publishes a comparative and comprehensive set of genuine savings estimates for over 150 countries which is called ‘adjusted savings’.[22]. [14] He holds that sustainability only makes sense in its 'strong' form, but that "requires subscribing to a morally repugnant and totally impracticable objective. As an example, the assessment will be different according to whether sustainability is seen from a weak or strong perspective. Other inadequacies of the paradigm include the difficulties in measuring savings rates and the inherent problems in quantifying the many different attributes and functions of the biophysical world in monetary terms. Ecological economists writing on the topic of sustainable development: Different ways of defining sustainable development: Informative work on the concept of strong sustainability: Capital approach to sustainability and intergenerational equity, Role of governance and policy recommendations, Criticisms of the strong vs. weak sustainability model, CS1 maint: multiple names: authors list (, International Society for Ecological Economics, Ecological economics § Weak and strong sustainability, Nicholas Georgescu-Roegen § Criticising neoclassical economics (weak versus strong sustainability), "the capital theory approach to sustainability: a critical appraisal", "Defining sustainability: weak sustainability", "Viewpoint: weak versus strong sustainability. While "Weak Sustainability" supporters mainly believe that these are substitutable, "Strong Sustainability" followers generally contest the possibility of inter-changeability.[16]. Although related subjects, sustainable development and sustainability are different concepts. An example of weak sustainability could be mining coal … This example shows how weak sustainability and substitution can be cleverly applied on a national scale, although it is recognised that its applications are very restricted on a global scale. [1][4] However, it only really came into the mainstream in the 1990s within the context of sustainable development discourse. This is key to the idea of intergenerational equity. The oil, a type of natural capital, was exported in vast quantities by Norway. Costanza, R., Norton, B. Weak form efficiency is one of the degrees of efficient market hypothesis that claims all past prices of a stock are reflected in today's stock price. Natural capital covers the stock of environmental assets such as fossil fuels, biodiversity and other ecosystem structures and functions relevant for ecosystem services. Taking that as well as the acute degradation into account, one could justify using up vast resources in an attempt to preserve certain species from extinction. Since the nineties, there has been an ardent debate on the substitutability between natural and human-made capital. In connected speech, many of the ‘small’ words we use very frequently tend to take on a different ‘shape’ from the one listed in the dictionary. It is important to note that, unconditional substitution between the various kinds of capital is allowed within weak sustainability. Later, Pearce and Atkinson[20] and Hamilton[21] added to Hartwick's rule, by setting out a theoretical and empirical measure of net investment in human and natural capital (and later human capital) that became known as genuine savings. He defines sustainability as implying something about maintaining the level of human welfare (or well-being) so that it may improve, but never declines (or, not more than temporarily). Weak versus strong sustainability. Washington D.C. Island press. 2.3 Weak Sustainability According to Neumayer (2003), "sustainable development is defined here to be sustainable if it does not decrease the capacity to provide non-declining per capita utility for infinity." Not just designing products that can be easily repaired. Washington D.C. : Island press. Sustainability can thus be directly related to resilience. Tell him to go strong forms /hɪm/ /tu:/ weak form: /tel əm tə gəʊ / As you can see, the grammatical words "him" and "to" are unstressed and have a weak form when pronounced inside a sentence Examples of strong and weak forms. However, chiefly as a result of the Asian financial crisis, the trust fund was almost entirely wiped out. 92-26. Weak Sustainability versus Strong Sustainability Jérôme Pelenc, Fund for Scientific Research (FRS-FNRS) and Free University of Brussels (ULB), Belgium ... manufactured capital and other forms of capital (human and social capital, etc.) Wilfred Beckerman[14] posits that the absolutist concept of sustainable development given above is morally repugnant. The question arises, whether or not one form of capital may be substituted by another. Often we see divergence, which of course makes the sustainability efforts fragile, lacking real commitment and prioritization. Ecosystem health: new goals for environmental management. He defines sustainability as implying something about maintaining the level of human welfare (or well-being) so that it may improve, but never declines (or, not more than temporarily). Sustainability: an interdisciplinary guide. Pronunciation is not based on spelling. Since the nineties, there has been an ardent debate on the substitutability between natural and human-made capital. Speculations on strong and weak sustainability. Contrary to weak sustainability, strong sustainability assumes that "human capital" and "natural capital" are complementary, but not interchangeable. This interdependence means that any sustainability-related issue must be considered holistically. When this accumulation is sufficiently rapid the effect from the shrinking exhaustible resource stock is countered by the services from the increased human capital stock. In very weak sustainability, the overall stock of man-made capital and natural capital remains constant over time. This implies sustainable development will not decrease over time. Natural capital covers the stock of environmental assets such as fossil fuels, biodiversity and other ecosystem structures and functions relevant for ecosystem services. Within the concept it is believed that the amount of capital a generation has at its disposal is decisive for its development. Another positive effect of introducing sustainability criteria is that products, which fulfill them, can later be linked to governmental subsidies [7]. Sustainability: an interdisciplinary guide. Decision makers, both in theory and practice, need a concept that enables assessment in order to decide if intergenerational equity is achieved. Beckerman's influential work concludes that weak sustainability is, “redundant and illogical”. According to Pearce and Atkinson's calculations, the Japanese economy is one of the most sustainable economies in the world. It is also important to note that strong sustainability does not share the notion of inter-changeability. The aim of governance therefore should be to keep genuine savings above or equal to zero. "[14] He goes as far to say that he regrets so much time has been wasted on the entire concept of sustainable development. The capital approach lends itself to this task. Contradictorily, it could be argued that even weak sustainability measures are better than having no measures or action at all. The ozone layer is one example of an ecosystem service that is crucial for human existence, forms part of natural capital, but is difficult for humans to duplicate.[10]. Pezzy, J. 1] Align strategy and sustainability: Management needs to make sure that the strategy of the company and the sustainability efforts are aligned. Daly, H.E. For example, what if ... Economic growth in some form is required for those who lack essentials, ... A defense of weak sustainability is offered by El Serafy (1996), while Common (1996) argues that the distinction between weak and strong sustainability is invalid. Another critical weakness of the concept is related to environmental resilience. Martinez-Allier's address[23] concerns over the implications of measuring weak sustainability, after results of work conducted by Pearce & Atkinson in the early 1990s. Costanza, R., Norton, B. The question arises, whether or not one form of capital may be substituted by another. In very weak sustainability, the overall stock of man-made capital and natural capital remains constant over time. Sustainability is usually understood as a form of intergenerational ethics that accommodates the economic, social, and environmental needs of current and future generations. It is based upon the work of Nobel Laureate Robert Solow,[1] [2] [3] and John Hartwick. Try the following exercise to practice both the weak and strong form. Ecological economists writing on the topic of sustainable development: Different ways of defining sustainable development: Informative work on the concept of strong sustainability: This article is licensed under the GNU Free Documentation License. Natural capital covers the stock of environmental assets such as fossil fuels, biodiversity and other ecosystem structures and functions relevant for ecosystem services. A key example of this is the World Bank, who now regularly publishes a comparative and comprehensive set of genuine savings estimates for over 150 countries which is called ‘adjusted savings’.[19]. A development is then called sustainable when it leaves the capital stock at least unchanged. This idea received more political attention as sustainable development discussions evolved in the late 1980s and early 1990s. 2. Contradictorily, it could be argued that even weak sustainability measures are better than having no measures or action at all. This commitment was demonstrated by the signing of Agenda 21, a global action plan on sustainable development. Daniel Bromley[29] uses the example of rainforests to illustrate his argument. Wilfred Beckerman[14] posits that the absolutist concept of sustainable development given above is morally repugnant. This high level of sensitivity within regional systems in the face of external factors brings to attention an important inadequacy of weak sustainability. Statoil ASA, a state-owned Norwegian oil company invested its surplus profits from petroleum into a pension portfolio to date worth over $325 billion. When the problem is phrased as ‘how much’ this always implies that some amount of a resource should be used and some left. World bank environment paper 2. It is based upon the work of Nobel Laureate Robert Solow,[1][2][3] and John Hartwick. At its inception, sustainability was interpreted as a requirement to preserve, intact, the environment as we find it today in all its forms. By focusing on bequests of specific rights and opportunities for future generations, we can remove ourselves from the "straightjacket of substitution and marginal tradeoffs of neoclassical theory". 7 examples of sustainability in Sweden Swedish cities have taken climate change to task, drastically helping to reduce the country’s greenhouse gas emissions. Pearce, D.W. and Atkinson, G.D. (1993) Capital theory and the measurement of weak sustainable development: an indicator of “weak” sustainability. Both of these factors provide a huge benefit to consumers and help reduce pollution. It began as an extension of the neoclassical theory of economic growth, accounting for non-renewable natural resources as a factor of production. This can be variously defined, dependent on The 3-legged stool metaphor reinforces the three dimensions that are required for us to enjoy a high quality of life— and shows that society is unstable if one of them is weak. Statoil ASA, a state-owned Norwegian oil company invested its surplus profits from petroleum into a pension portfolio to date worth over $1 trillion. The idea of leaving capital stock at least unchanged is widely accepted. minerals, water) tend to be the most frequently cited examples. The resultant fund allows for long-lasting income for the population in exchange for a finite resource, actually increasing the total capital available for Norway above the original levels. 2 *Adapted and modified from the Finance Project Framework. This is the focus of the debate between ‘weak’ and ‘strong’ sustainability, and how intergenerational equity is to be achieved. Decision makers, both in theory and practice, need a concept that enables assessment in order to decide if intergenerational equity is achieved. Thus, they suggest that it is the gross negligence of factors other than savings in measuring sustainability that makes weak sustainability an inappropriate concept. Some even suggest that the concept of sustainability is redundant. This means that natural resources may decline as long as human capital is increased. Money from the mining of phosphate enabled the establishment of a trust fund, which was estimated to be as much as $1 billion. Sustainable development concepts:an economic analysis. another example: I would like some fish and chips These are but a few of many varying examples of models for sustainable tourism development. "[14] He goes as far to say that he regrets so much time has been wasted on the entire concept of sustainable development. Weak sustainability has been defined using concepts like human capital and natural capital. Actually, all forms of supply chain software support sustainability, with transportation management systems and supply chain design solutions being … He argues that such a task would involve using resources that could have instead been devoted to more pressing world concerns. Other inadequacies of the paradigm include the difficulties in measuring savings rates and the inherent problems in quantifying the many different attributes and functions of the biophysical world in monetary terms. Ecosystem health: new goals for environmental management. Defining sustainability: weak sustainability, Viewpoint: weak versus strong sustainability. [29] The social bequest approach looks at the problem in a different light by changing to what, rather than how much, we leave to future generations. The reason for this is that its saving rate is so high. 8 Examples of strong and weak sustainability. Pezzy, J. The integrative sustainability model has the economy completely located within society and society completely located within the environment. Daly, H.E. With this in mind, weak sustainability can cause extreme sensitivity to either natural disturbances (such as diseases in agriculture with little crop diversity) or economic disturbances (as outlined in the case study of Nauru above). The integrative sustainability model has the economy completely located within society and society completely located within the environment. Although related subjects, sustainable development and sustainability are different concepts. 1993. Weak sustainability is an idea within environmental economics which states that 'human capital' can substitute 'natural capital'. An example of the benefit to human capital could include increased financial profits. Weak sustainability has been defined using concepts like human capital and natural capital. Unlike weak sustainability, strong sustainability puts the emphasis on ecological scale over economic gains. Top 5 Examples of Sustainable Development Solar Energy: The greatest advantages of solar energy are that it is completely free and is available in limitless supply. Others have suggested a better approach to sustainability would be that of "social bequests". A teacher has to give due attention to it along with everything else. Examples include increasing access to clean drinking water or sanitation in the Third World. cooking, lighting, heating, refrigeration and operating boreholes to supply water in some villages) and for industrial purposes (growing the economy by producing other resources using machines that are electricity operated.). An example of strong sustainability could be the manufacturing of office carpet tiles from used car tyres. For Costanza and Daly (1992), Weak Sustainability is concerned with maintaining the total capital stock intact, without regard to the partitioning of that capital among the four kinds. Towards an ecological economics of sustainability. This idea received more political attention as sustainable development discussions evolved in the late 1980s and early 1990s. Case studies of weak sustainability in practice have had both positive and negative results. A prime example of a weak sustainability is the Government Pension Fund of Norway. The result is that sustainable development requires the conservation of plant and animal species’. The resultant fund allows for long-lasting income for the population in exchange for a finite resource, actually increasing the total capital available for Norway above the original levels. The result is that sustainable development requires the conservation of plant and animal species’. Genuine savings measures net changes in produced, natural and human capital stocks, valued in monetary terms. [18] Concurrent with this extraction, Nauru's inhabitants, over the last few decades of the twentieth century, have enjoyed a high per capita income. centre for the management of environmental resources. Turner, R.K. 1992. [11], To understand the concept of weak sustainability, it is first necessary to explore the capital approach to sustainability. The oil, a type of natural capital, was exported in vast quantities by Norway. [22] This case presents a telling argument against weak sustainability, suggesting that a substitution of natural for man-made capital may not be reversible in the long-term. Values Economic approaches to sustainability frame the issue in terms of human wellbeing (utility). For the best possible sustainability protection, it is desirable that s… This means that natural resources may decline as long as human capital is increased. This point of view can be considered to be flawed since the world would (arguably) not be sustainable if all countries have the resource intensity rate and pollution rate of many industrialised countries. 1991. Common, M. & Perrings, C. 1992. Some critics have gone one step further, dismissing the entire concept of sustainability. Genuine savings measures net changes in produced, natural and human capital stocks, valued in monetary terms. According to Van Den Bergh,[28] resilience can be considered as a global, structural stability concept, based on the idea that multiple, locally stable ecosystems can exist. The largest part of the world's population live in acute poverty. Sustainability can thus be directly related to resilience. Hartwick's rule, is often referred to as "invest resource rents", where ‘rent’ is payment to a factor of production (in this case capital) in excess of that needed to keep it in its present use. It is also important to note that strong sustainability does not share the notion of inter-changeability. In other words, the economy is a subset of society and society is completely dependent upon the environment. Solow showed that, given a degree of substitutability between human capital and natural capital, one way to design a sustainable consumption program for an economy is to accumulate man-made capital. The Program Sustainability Assessment Tool, copyright 2012, Washington Martinez-Allier's address[23] concerns over the implications of measuring weak sustainability, after results of work conducted by Pearce & Atkinson in the early 1990s. CSERGE working paper GEC. This trend still remains today and therefore exceeds depreciation on both natural and man-made capital. If we decide to use 25% of a rainforest and leave the rest, but then the next time we make a decision we start all over again and use 25% of what's left, and so on, eventually there will be no rainforest left. The products created by mankind cannot replace the natural capital found in ecosystems. A less positive case is that of the small Pacific nation of Nauru. Beckerman's influential work concludes that weak sustainability is, “redundant and illogical”. Money from the mining of phosphate enabled the establishment of a trust fund, which was estimated to be as much as $1 billion. By their measure, most of the Northern, industrialised countries are deemed sustainable, as is the world economy as a whole. Although related subjects, sustainable development and sustainability are different concepts. CSERGE working paper GEC. Strong & Weak Forms. Compare and contrast the weaknesses and strengths of the so-called ‘weak sustainability’ and ‘strong sustainability’ policy approaches to address and resolve environmental problems/issues in both the short-term and long-term. [21] Concurrent with this extraction, Nauru's inhabitants, over the last few decades of the twentieth century, have enjoyed a high per capita income. Within the concept it is believed that the amount of capital a generation has at its disposal is decisive for its development. In this sense it is similar to green accounting, which attempts to factor environmental costs into the financial results of operations. [14] This allows for some natural resources to decrease as long as sufficient compensation is provided by increases in other resources. The result usually was an increase in human capital. What do you want to do this evening? [27], Another critical weakness of the concept is related to environmental resilience. 1992. Sustainable development is “development that meets the needs of the present without compromising the ability of future generations to meet their own needs” – World Commission on Environment and Development, 1987 Basically, sustainable development is a long-term solution to how we plan our indefinite progress in the future without causing damage to the environment so as to …
