(eds. For instance, many tropical fisheries are managed according to an "open-access" rule. Handbook on Social Capital, Edward Elgar, Northhampton. One easy example of a market failure is the monopoly outcome. A strong community can indeed help in overcoming the collective action problems linked with the institutional change, a fact that actually happened in some of the most successful among of the studied cases. Design Principles and Common Pool Resource Management: An Institutional Approach to Evaluating Community Management in Semi-arid Tanzania. Give Some Policy Advise. OSTROM E., 2005. The interface between formal and informal institutions 16 3.3. What is the tragedy of the commons? This was the situation of cattle herders sharing a common parcel of land on which they were each entitled to let their cows graze, as was the custom in … C ommon-pool resources are the resources made available to all for consumption and the excess to which can only be limited only at high cost.. Common-pool resources are natural or man-made resources shared among different users, a condition that produces a competition for their utilization leading often (although not necessarily) to their degradation or even to their destruction. Where substantial temptation exists to engage in opportunistic behavior, no set of rules will be self-enforcing (V. Ostrom, 1980). Thus, the CPRs share characters with both the private and the public goods, namely a high subtractability with the former ones and a low possibility of exclusion with the latter ones (Figure 1). Examples of common-pool resources include irrigation systems, fishing grounds, pastures, forests, watero… This is the tendency for individual users to exploit limited resources to capture benefits that would otherwise go to their competitors. 4, pp. HARDIN G., 1968. The gap between theory and policy 13 2.2. TANG S.Y., 1992. the shared values and wordviews and the existing network of social relations (Auer, 2006). Some scientists consider the exponential growth of the human population to be an example of a tragedy of the commons. The true measure of our project’s success will be the extent to which we can apply our methods to improve existing market institutions in Australia and the western United States, and to guide the design of new institutions in other places facing imminent water crises. – “Istituzioni e capitale sociale nella gestione di risorse comuni: Il caso dei sistemi di irrigazione valdostani”. (eds.) The association was created at the beginning of the twentieth century, when crops were combined and planted in rotation in order to maximize both soil fertility and yields. Overuse of common resources often leads to economic problems, such … Globally pervasive concerns about environmental degradation and resource depletion have stimulated this growth. Common pool resources can have public or private owners. Figure 1. 2, pp. Any one of the landowners can drill down and extract oil under his/her land and sell the oil on the market. Fisheries and forests are examples of two common-pool resources that are currently of great concern. Alternatively, it can be viewed as an attribute of individuals that enhances their ability to solve collective action problems (Ostrom and Ahn, 2008). Rassegna Italiana di Sociologia, vol. Introduction. Since our paper basically adopt this approach, will be discuss it in details later. Earthscan, London. The literature on common pool resources and common property has grown swiftly in the last two decades (see reviews in Ostrom et al. 18Due to the overuse of the groundwater sources and to the end of the traditional crop rotation practices in favor of corn monoculture, the farmers have recently experienced a significant reduction of water availability. ICS Press, San Francisco. – “The tragedy of the commons”. Cet article présente brièvement la théorie des ressources communes développée ces vingt dernières années par Elinor Ostrom et ses collègues, et l’illustre par plusieurs études de cas de systèmes d’irrigation du nord de l’Italie (Lombardie et Vallée d’Aoste). Island Press, Washington D.C. CONNOR R., DOVERS, S., 2004. – “Artisanship and artifact”. A common property rights regime system (not to be confused with a common-pool resource) is a particular social arrangement regulating the preservation, maintenance, and consumption of a common-pool resource. All those schemes have, however, one point in common: the presence of an institution that defines clear exploitation rights and creates the right incentives in order to avoid overuse. International Journal of the Commons, vol. 12The research, conducted a few years ago using the IAD framework as underlying scheme, covered nine irrigation systems located in different areas of the region. According to Ostrom (2005), the main community attributes affecting the action arenas are the values shared among users, the level of common understanding that potential participants share (or do not share) about the structure of particular types of action arenas, and the extent of preference homogeneity among the community members. KEOHANE, R.O., LEVY, M.A. Buck, 1998; Keohane and Levy, 1994). 1 Common-pool resources (CPRs) are natural or man-made resources shared among different users, a condition that produces a competition for their utilization leading often (although not necessarily) to their degradation or even to their destruction. Social capital is usually the product of a past history of tight relationships and little social capital exists when large numbers of heterogeneous individuals act in an unknown situation. a. Wi-Fi b. Without entering the details, it is worth noting that the functioning of the CPR governing institutions are indeed not only dependent from the physical attributes of the resource — e.g. Common pool resources have value that can be diminished if the resources are used at a rate higher than can be replenished. The river is a heavily exploited common water resource. Complexities 15 3.1. Common-pool resource, a resource made available to all by consumption and to which access can be limited only at high cost. One of the greatest challenges we face when managing natural resources for long-term human benefit is the “common pool” problem. Social-ecological system literature resulted in a wide number of theoretical an empirical works that studied a vast variety of management practice cases from the point of view of their effects on ecosystem dynamics and their capacity to learn from and to adapt to the feedback coming from the natural environment. This field of inquiry currently represents one of the most interesting new fields in the study of human-environment relationship. 92, pp. For example, consider a pasture. When institutions are well crafted, opportunism is substantially reduced. The associations differed also with respect to both the rules in use for managing water withdrawals and channel maintenance and to the monitoring arrangements. Motivated by these emerging efforts, our project, “Improved management of common pool resources,” joins MIT researchers in Engineering and Economics to identify optimal water management practices, based on more realistic models of dynamic common pool resource use and newly available empirical evidence from fledgling markets. Giangiacomo Bravo et Beatrice Marelli, « Irrigation systems as common-pool resources », Revue de Géographie Alpine | Journal of Alpine Research, 96-3 | 2008, 15-26. GUNDERSON L.H., HOLLING C.S. To illustrate this problem more clearly, we can take the case of forest resources as a common pool resource. In this case, the common resource is the planet Earth and all its shared resources. This article presents a conceptual framework for theoretical and empirical analysis of the multiplicity of behavioral problems encountered in common-pool resources (CPRs). Question: Explain The Tragedy Of The Commons In The Example Of The Brazilian Fishermen Exploiting A Common Pool Resource (Fehr And Leibbrandt 2011 ). We use the term common-pool resources (CPRs) to refer to resource systems regardless of the property rights in-volved. ), 1998. centralized management, private rights, co-management or a combination of different regimes — in order to avoid Hardin’s tragedy (Marshall, 2005; Ostrom, 1990, 2005; Ostrom et al., 1994). ICS Press, San Francisco. OSTROM E., AHN T., 2008. Having a common-pool resource be non-exclusive implies that it is impossible or infeasible to exclude others from appropriating the good. Interdiscipinary Lessons from Experimental Reseach. This happened mainly through to the concept of social-ecological system, an expression that emphasizes the linkages existing between humans and the natural systems where they live. Other meteorological and geological characteristics of the territory, like the dry winds and the strong insolation of the mountain southern sides, contribute to the relative aridity of the fields that need intensive artificial irrigation in order to enhance their productivity. an irrigation system or fishing grounds), whose size or characteristics makes it costly, but not impossible, to exclude potential beneficiaries from obtaining benefits from its use. It is relatively easy to include this new variable in the IAD Framework thanks to the concept of social capital. The policy challenge 14 3. – Local Commons and Global Interdependence. Common pool resources are sometimes called In this case, the strength of the community represents a factor that goes against the association interest. Ostrom, 1990, 1998, 1999, 2005; Ostrom and Ahn, 2008) has recently shown that a successful CPR management implies an institutional construction able to take adequately into account, among the community attributes, the values shared among the resource users. The IAD framework is an important research tool that highlights the basic elements to consider in a CPR study, along with the relations among them (Fig. Cambridge University Press, Cambridge. ), 2002. The research has been conducted using the IAD Framework (Fig. Public Goods and Common-pool Resources. That is because of a common agreement among villagers that one is allowed to graze more cows on the meadow than they can care for over the winter—a rule that dates back to 1517. – Understanding Institutional Diversity. 1.3. 8III) Most of the theoretical work on large scale resources started only in the middle Nineties as direct extension of small-scale CPR research, an approach that led to emphasize the common aspects of the different levels of analysis (e.g. By conducting a cluster analysis on our data, we found that three subgroups exist inside the community. Brescia is the most extended province of Lombardy, an Italian region that encompasses the Retican Alps. Explain and give an example of a common-pool resource, and describe ways of protecting such resources. Ostrom has documented similar effective examples of “governing the commons” in her research in Kenya, Guatemala, Nepal, Turkey, and Los Angeles.

Public Administration Review, vol. Combining expertise in economic and scientific modeling may also help to narrow the gaps between the complex models often used by scientists and engineers and the stylized models favored by economists, and between analytical, academic methods and management practice—and thereby help to convince regulators and governments to implement the practical environmental solutions that we propose. Paavola, 2008). Its results will be here only shortly presented since the reader interested in a deeper discussion of the cases can find further data in Bravo (2002). – “Institutional rational choice: An assessment of the IAD framework”. This problem has been solved! ), 2001. Westview Press, Boulder. For example, forests may be over-harvested and bodies of water may be overfished. 309-317. All these natural resources are common goods and, therefore, common pool resources. While this approach led to some immediate significant results, it probably under-recognized the important differences linked with the scale increase (especially when considering the global commons) in terms of heterogeneity of the stakeholders, governance capabilities, and constitutional-choice institutional rules (e.g. The market failures in these settings are related to the problems we saw with negative and positive externalities. timber from a forest, water from a basin, etc.) Regions and countries manage and sustain oceanic resources and services with varying degrees of success. – “Governing atmospheric sinks: the architecture of entitlements in the global commons”. 5Subsequent works expanded Ostrom’s insights. Especially important is the level of trust that the association members experiment toward the institution, i.e. Nevertheless, excessively closed communities, with fundamentally backward looking values and worldviews, tend instead to respond negatively to any innovation hypothesis. , 2003. The adequate management of a common-pool resource requires a deep understanding about the causes of (potential/existing) conflict in resource use. 1. This means that all those interested in harvesting fish within these fisheries has free access to the resource. The associations manage and maintain the centuries-old channels and often make substantial improvements regarding the transportation and distribution techniques. ICS Press, Oakland. The nine associations presented major differences in terms of both the factors affecting the action arena and the outcomes of the interaction process. 2) as underlying scheme and opting for a qualitative method of data collection, which comprised in-depth interviews and the submission of semantic differential to a large share of the community members, including the association board members. An open access resource such as a fishing ground, an irrigation system, or a forest is called a common-pool resource (CPR). As a consequence, each person with access to the resource has an incentive to exploit currently as much as he profitably can, The Evolution of Institutions for Collective Action. This would be an example of a. a nonrenewable resource b. a private good c. the common pool problem d. a positive externality e. a renewable and excludable resource. 2). Effective water management depends on whether regulators can connect institutional design with environmental processes and economic incentives. Journal of Policy Analysis and Management, vol. – Institutions and Collective Action: Self-Governance in Irrigations. In order to decrease opportunistic behavior, coordination activities such as monitoring and sanctioning may have to be increased. Three classes of external factors affect the structure and the functioning of action arenas: the states of physical world where actions are undertaken; the rules in use by participants to order their interactions; the structure of the community where participants act. We found indeed that those factors are dependent from the community past experiences and from the capacity of its members to recognize a major common interest in preserving the resource. 1.2 The Confusion between a Resource System and a Property Regime To add to the confusion, the term ‘common-property resource’ frequently is used to describe a type of economic good that is better referred to as a ‘common-pool resource.’ Traditional examples of common-pool resources include fisheries, water systems, and grazing lands. Similarly to the Vallée d’Aoste cases, a number of changes in the external context played a significant role in producing this outcome. 14The main result of the research is that, besides the obvious fact that larger water availability at the source helps in reaching an adequate level of irrigation of the plots, the community represents a major factor that influences the outcomes of interaction in the different action arenas and, consequently, the overall performance of the associations. Recentralizing While Decentralizing: How National Governments Reappropriate Forest Resources. Lam, 1998; Ostrom, 1992; Tang, 1992; Uphoff, 1986). Svendsen, G. L. Svendsen (eds.) rivalry of consumption) (Ostrom et al., 1994, 6–8). Solutions to Problems of the Commons. American Political Science Review, vol. 23The costs of monitoring and sanctioning activities necessary to eradicate opportunistic behaviors are often not affordable for local communities of users, because controlling opportunistic behaviors involves both a reduction of “free-riding temptations” and a high likelihood of being discovered when transgressing a rule. – Panarchy: Understanding Transformations in Human and Natural Systems, Island Press, Washington DC. The values put on specific uses will vary depending on the use or interest of the various community actors. In particular, we hope to develop a general method for using performance data to guide market design in environmental settings. As mentioned above, examples of typical common-pool resource systems include lakes, rivers, irrigation systems, groundwater basins, forests, fishery stocks, and grazing areas. BUCK, S.J., 1998. An irrigation system is actually composed by two different common resources: the channel(s) and the water. With common-pool resources, overuseNegative ExternalitiesNegative externalities occur when the product and/or consumption of a good or service exerts a negative effect on a third party outside the market. In the introduction, the two main kinds of solutions to commons problems were outlined -- government, or public solutions, and private solutions.In this section, we detail them further in the following order: Government Solutions We use differential game theory to show that cooperative allocation of water based on welldefined ownership rights can provide greater benefit to all users than a non-cooperative arrangement that leads to overexploitation. In this process, common values and shared norms can make the difference, thanks to the establishment of internal commitment and punishment that push the actors to respect the rules in use and hence reduce the monitoring and sanctioning costs. Common Pool Resources Some negative externality problems result from the existence of a “common pool resource.” A common pool resource is a resource that has most of the characteristics of a pure private good, but that is owned in common by many people (such as the members of a community). Our empirical analysis discusses the extent to which this variation can be explained by common-pool resource (CPR) characteristics, controlling for institutional quality, island status, the existence of marine-protected areas, and the ratification of marine environmental agreements. 2This paper shortly discusses the “theory of the commons” as developed in the last 20 years by Elinor Ostrom and her colleagues (e.g Ostrom, 1990, 2005; Ostrom et al., 1994, 2002) and illustrates it by mean of case studies regarding a number of irrigation systems in Northern Italy (Lombardy and Vallée d’Aoste). Examples may include pastoral land in communities that practice pastoralism, fishing waters for the fishing communities, forestlands for societies that do logging. – Trust and Reciprocity. The project’s PhD students, an engineer (Anjuli Jain) and an economist (Will Rafey), provide parallel contributions. – The Global Commons: An Introduction. – Governing Irrigation Systems in Nepal: Institutions, Infrastructure, and Collective Action. However, reciprocity establishes mainly thanks to reputation, values and practices that spread mutual trustworthiness among all community members. MARSHALL G.R., 2005. The post What is the tragedy of the commons? Get the latest on ESI news and events, plus our weekly newsletter. The next section will explore the interplay among those different elements by presenting different case studies of irrigation systems located in Northern Italy. Furthermore, the rainfalls are mainly concentrated during the Spring and the Autumn, with a very dry summer. This is the tendency for individual users to exploit limited resources to capture benefits that would otherwise go to their competitors. 5 problem also extends to theft of the value of public goods. In P. Sabatier (ed.) According to Ostrom et al. A common resource is a resource, such as water or pasture, that provides users with tangible benefits.
