1. INTRODUCTION

The present arising danger of climate change due to increasing environmental hazards as a result of human activities and a global economic recession recently occurred caused by the pandemic and the conflict between Russia and Ukraine spotlighted more than ever that the efficient utilization of resources is substantial for civilization to survive. Humanity strives to maintain the comfort and wealth provided by technological and industrial developments while noticing the necessity to transform conventional methods into sustainable techniques since it has failed them so far. In this regard, Hardin's dilemma remains significant in our endeavour for an innovative approach to the issue.

This article will be divided into three parts to be assessed under the following issues. First, what is Hardin's dilemma that is manifested in the "Tragedy of the Commons"? Second, the existing regulations on the transboundary harm principle within the scope of geoengineering activities. Third, which steps should be taken to avoid transboundary disputes in the future to protect “Climate” as a common good considering Hardin's theory? This research seeks to question whether Hardin's dilemma offers solutions to contemporary transboundary disputes and aims to envisage a functioning legal system for the protection of the commons.

2. HARDIN'S VISION OF THE JOURNEY TOWARD DOOM.

An allegory of a pasture opens to all, where herders could graze their animals without restrictions is projected in the Tragedy of the Common. Hardin suggests that each herder will try to increase their cattle number as much as possible to maximize their gains. According to Hardin, this will lead to overgrazing and eventually to the complete depletion of that common resources. Individuals are presumed to act in this way with pragmatic incentives since they may think that the benefits obtained from exploitation are exclusive to themselves, while the negative impacts are spread to the community as a whole.[1] It has been argued that any technical remedy to address this issue is inadequate, due to the constantly increasing human population, which is at the core of the tragedy. In this framework, two basic solutions are determined, which envisage the allocation of resources to an organization[2] and limit the freedom of reproduction.[3]

The primary arguments expressed by Hardin have been criticized for several reasons by various pieces of research over time. One issue pointed out in that direction is, Hardin constructed his argument based on presumptions about human nature.[4] Another criticism is that Hardin inaccurately defined the common as a concept due to a historical misconception and this results in the exclusion of cultural and political dynamics.[5] However, certain essential points have been made by Ostrom. As Ophuls later supported it with the idea of ​​Leviathan,[6] without supervisory intervention, common goods were destined to be extinct, this projection of a hopeless future is not allowing any remedies other than promoting an external force to restrict the right to breed and allocate common resources to an organization. This idea founded on distrust of humanity may direct the world to seek centralized regimes.[7]

Hardin's proposed remedies for the tragedy of the commons fail to account for the significance of incorporating traditional knowledge and practices of local and indigenous communities,[8] as well as the substantive value of indigenous knowledge, which is also emphasized by Wall Kimmerer.[9] Hardin's critique of technical solutions to the tragedy of the commons is largely unsupported by empirical evidence.[10] This mode of reasoning may be considered insufficiently persuasive and lacking in rigour within academic circles given that contrary ideas are constructed on solid bases, promoting technological developments for renewable energy to maintain sustainable economic order.[11] Although Hardin responded to some critiques of his original essay by elaborating on his earlier arguments and proposing new solutions to address the issues of overpopulation and resource consumption,[12] the basic concept of the tragedy of the commons remained largely unchanged. Nevertheless, the "Tragedy of the Commons" remains relevant for transboundary disputes, as it highlighted persistent concerns over the use of natural resources and emphasized the lack of certain legal protection for the commons.[13]

3. GEOENGINEERING AND TRANSBOUNDARY HARM PRINCIPLE: CLIMATE AS A COMMON GOOD.

"The climate is a common good, belonging to all and meant for all.”[14] This statement can be considered for a moment as an academic disclosure. In fact, it has been expressed by a religious authority Pope Francis in 2015. Nevertheless, the assessment of climate as a common good in a legal document goes way back as set out in the third article of the United Nations Framework Convention on Climate Change, entitled principles.[15] Since then, the protection of the climate gradually became a more debatable topic. The issue has two dimensions. Effects of the increasing threat of climate change become more evident, for example on water resources,[16] agriculture,[17] and human health[18] forcing us to search for technological solutions. However, the possible risks and benefits of climate engineering activities, such as Stratospheric Aerosol Injection, remain uncertain.[19] SAI aims to reduce the negative effects of greenhouse gas emissions by injecting aerosol into the atmosphere to increase the reflection of sunlight, so it can mimic the natural function of a volcanic eruption.[20] However, several potential risks of it pointed out, for instance, it may cause ozone depletion[21] and stratospheric heating,[22] and uncertain climatic consequences[23].

Similar technological projects are applications that are effective on a global scale and therefore have global consequences. Possible damages as a result of these activities may constitute a violation of the transboundary harm principle.[24] Transboundary harm is an engrained environmental law principle, that obliges countries to prevent causing damage to the areas beyond their territorial limits.[25] This principle can be traced back to the Trail Smelter case where it has been determined by the Tribunal Court that, no State has the right to use or permit the use of its territory in such a manner as to cause injury by fumes in or to the territory of another or the properties or persons.[26]

Few international legal sources directly regulate transboundary consequences of climate modification so far. However, we can address relevant multilateral international agreements to define responsibilities and legal remedies for the transboundary consequences of geoengineering activities.[27] Article 3 of the UNFCCC assigns active responsibility to the parties to protect the climate system.[28] COP 10 Decision X/33 of the Convention on Biological Diversity, complementary to article 3 in terms of climate engineering regulations. States that, "No climate-related geoengineering activities that may affect biodiversity take place until there is an adequate scientific basis on.”[29]Nonetheless, the enforceability of this regulation may be controversial considering the precautionary approach. Resolution LP.4(8) of the London Protocol is another document that regulates ocean fertilization activities and other marine geoengineering activities in a science-based global, transparent, and effective way.[30] Also, Burns claimed that the Paris Agreement[31] implicitly provides protection from a human rights perspective[32].

4. “WE THE PEOPLE”, TO DEFEAT THE TRAGEDY.

Hardin argued coercive laws should be implemented to preserve commons.[33] International environmental law struggled to enforce multilateral regulations for various reasons so far. Concerns arising from geoengineering may provide the compelling element we need to address this issue. Although there has been no international conflict stemming from climate engineering yet, technological research in this field is increasing rapidly and problems are commencing to appear. One example is, Mexico recently announced new measures to prohibit solar geoengineering tests in the country, following an experimental program launched by a US startup.[34]

Previously, transboundary harm pollution spawned a conflict at the regional level on the protection of other common goods. Regardless of whether we decide to initiate geoengineering programs or not, countries will be forced to take collaborative actions when environmental breakdown is imminent. The consensus at the global scale to deal with it, is indispensable, unlike other transboundary harm disputes. This may provide legitimacy for coercive laws to demand nations compromise their sovereignty. Eventually, it can be argued that international environmental law must establish a coercive unifying organization that is sovereign over member countries and able to impose its common regulations, as Ophuls suggested centralism as a remedy by extending Hardin’s ideas.[35] However, on a national scale, such an approach did not yield positive results in terms of solving environmental problems in China for instance. Despite having absolute authority and introducing various environmental regulations, the state has not been able to solve serious air pollution problems.[36]

An alternative solution may be to invite people to be knowledgeable about environmental issues and take action. Aarhus Convention determined three objectives called “pillars” to achieve this purpose[37] which are access to information, public participation, and access to justice.[38] The European convention on human rights is another international treaty that allows individuals to seek legal protection on environmental values,[39] has brought solid shreds of evidence that many people are aware of the consequences of ambitious exploitation of nature and are sensitive enough to pursue a way of living in harmony with it, contrary to Hardin’s assumption about human nature. Accelerating procedural processes and reducing costs by establishing and promoting new alternative dispute-resolution mechanisms[40] can be an important step in increasing incentives in this direction.

In conclusion, climate change and climate engineering controversies can form the basis of legitimacy for creating enforceable transboundary regulations and international organizations in the future due to its sui generis relationship to transboundary disputes. In such a case, countries will have to compromise their sovereignty to work cooperatively. However, a top-down mentality suggested by Hardin should be avoided since the laws enacted with centralist and oppressive methods proved to be unsuccessful. Therefore, empowering mechanisms that ensure public participation should be promoted. Contrary to Hardin’s view of a system based on distrust of people, a system that seeks solutions in people may be a promising approach for the future.
