Half of the World’s Trade Travels through it, but are we Protecting it?

>Environmental Challenges in the Indian Ocean Region

By Kanchana Wickramasinghe, Research Officer – IPS

The Indian Ocean rim region, home to around one-third of the world’s population, possesses a significant strategic economic value. Nearly half the world’s container traffic and 70% of the total traffic of petroleum products is accounted for by the Indian Ocean. 60,000 ships transit through it each year. So, the geo-strategic significance of it is well established, and discussed extensively in strategic affairs forums. Yet, the environmental challenges facing the Indian Ocean, and the rim countries, often receive less attention.
Environmental issues can significantly affect the region’s economic activities and environmental stability. While the natural environment in the Indian Ocean is faced with a plethora of threats, this post takes a quick look at some of the critical challenges which need to be addressed. – ocean resources, climate change, bio-security, and marine pollution.

Key Challenge 1: Ocean Resources
The Indian Ocean possesses a range of valuable natural resources including sea minerals, coral reefs, etc. Coral reefs are under the threat of depletion due to global climate change, direct human pressures, and inadequate governance, awareness, and political will (Laipson, 2009). Coastal ecosystems and recreational services provided by them play an important role in tourism, fisheries, livelihoods of coastal communities, etc., in the rim countries. Therefore, degradation of coastal ecosystems can have negative impacts on national economies. The region also possesses enormous amounts of economically valuable mineral resources and energy resources (both oil resources and renewable energy resources) which remain less exploited. Utilization of these resources needs to be done collaboratively by the rim countries as such activities can have detrimental impacts on the marine environment. Additionally, territorial claims by the rim countries and related political aspects also have become important concerns in the recent past with regard to natural resources usage as well as conservation in the Indian Ocean region.
Key Challenge 2: Climate Change
The Indian Ocean region is highly vulnerable to the impacts of climate change. The region hosts a significant proportion of poor, living in areas highly vulnerable to various impacts of climate change. The countries have varying but limited capacity to cope with the impacts of climate change, which can come in the forms of extreme weather events, sea level rise, to name but a few. In addition, climate change is linked with other regional environmental issues – loss of biodiversity, for instance – which can have serious negative economic impacts on development in the region. Taking adaptive measures to face the impacts of climate change remains one of the top development priorities for Indian Ocean rim countries.
Key Challenge 3: Bio-security
Marine bio-security refers to the protection of marine environments from non-indigenous species, and this has direct implications on biodiversity in the marine ecological systems in the Indian Ocean. It has been found that invasive alien species (IAS)1 are becoming a significant threat to marine biodiversity, where ballast water2 is viewed as a major cause of their proliferation. However, comprehensive studies on bio-security are rarely found in the case of the Indian Ocean, and it is becoming increasingly important to assess the marine bio-security risks for Indian Ocean rim countries. Structured and transparent evaluation techniques are needed in dealing with the issues related to bio-security, both in ecological and socio-political perspectives, supported with knowledge and resources to properly inform appropriate actions (Campbell, 2009). Bio-security requires the cooperation of a range of actors including scientists, policy makers, law enforcement officials, etc., and therefore collaboration mechanisms as well as joint research and knowledge sharing on this subject at regional level is key.

Key Challenge 4: Marine Pollution

The Indian Ocean region is also vulnerable to high levels of pollution caused by ocean dumping, waste disposal and oil spills as a significant amount of international trade takes place in the region’s waters. The wastes pose threats to the survival of marine organisms and consequently, on the marine ecosystem, on which millions of livelihoods depend. In addition, being bordered by fast growing economies such as India and China, as well as other East Asian economies, there is a high possibility of more industrial waste disposed to the ocean. Eutrophication of near-shore environments due to pollution from land-based sources and their run-off has impacted economic activities such as fisheries, tourism and also affected fragile ecosystems.

Way Forward: Greater Regional Cooperation
The twenty seven countries located on the rim of the Indian Ocean must bear in mind that they are affected not only by the economic significance of this ocean, but also the environmental challenges facing it.
When the environmental challenges are regional in nature, national level policies and strategies of individual countries alone are insufficient. Future actions have to take cognizance of the fact that environmental challenges are inherently interrelated and complex. There needs to be a regional level cooperation to deal with the environmental challenges which are common to all Indian Ocean rim countries. As at now, such challenges in are not adequately managed through regional policies, laws, multilateral agreements, or in the least regional collaboration by scientists and experts. The various issues related to the ocean environment are interlinked and caused by a complex of man-made and natural factors. Therefore, the formulation of regional policies and strategies has to be supported with comprehensive research which brings in actors from all relevant disciplines, from the entire region.
The UN Convention on the Law of the Sea is relevant to the issues regarding Ocean Sciences and Environment. The important features of the Convention includes navigational rights, territorial sea limits, economic jurisdiction, legal status of resources on the seabed beyond the limits of national jurisdiction, passage of ships through narrow straits, conservation and management of living marine resources, protection of the marine environment, a marine research regime and most importantly, a binding procedure for settlement of disputes between States. Collaboration among the states in our region is key to make the Convention operate effectively.

To address this regional challenge, we require regional solutions. The IOR-ARC (Indian Ocean Rim Association for Regional Cooperation) should take up this issue as a priority item in its future deliberations.

    A serious issue to discuss indeed and thank you very much to raise this. I do strongly agree with you about the major issues and challenges that you have mentioned here. Let me supplement some of my thoughts with this article's contents:

    (i) It is very important to evaluate the extent of such degradations, of each type, which are happening due to increasing human interference on the ocean ecology to give a clear message to our policy makers for undertaking appropriate measures with all other stakeholding countries;

    (ii) Can we also make an assessment of the current economic benefits, including benefits from shipping activities, extraction of ocean resources–including biologcal resources, the region is currently reaping from the Indian Ocean? Also how much these benefits can be affected by imposing environmental concerns on our economic activities (which should not be seen as a barrier to normal economic activitiues, rather helpful for ensuring long term and sustainable benefits) on the normal activities (which are not always environment-friendly)?

    (iii) We, the environmental research community in the region, can also take certain initiatives to raise the issue and make awareness about it's importance both at the policy and general public level. What can be some efficient ways for us to do so?

    >To overcome the key challenge 3- bio security, there has an option, but costly. to overcome the threat of IAS coming from ballast water, could build a large tank kind of thing near to the harbor or port to fulfill the need of use of ballast water by minimizing the threat to ocean. the method using in the manufacturing and releasing a ship in to the ocean could use for manage this situation. then the species as red-starfish find in the tank mentioned above (ballast water tank)could export to the countries they are origin from, will make some income to the country. usually those species are not invasive for their origins. they got invasive in to these tropical countries because of the most appropriate weather conditions at tropical countries. but their behaviors and growth rates at their origins may different than tropical environments. by built a ballast water tank the total polluting area by there IAS will getting small and management of the issues will get easy. but manage invasive algae species and microscopic species may difficult than others- macro species. but this method will helps to minimize the threat.

    ideas to overcome other challenges is not coming to the mind.. because all or these things should think inline with the global business environment. making rules and policies may easier than implementing strategic solutions and sustainable policies with self disciplines.

    >Indeed, a lot research studies have to be carried out to assess the environmental costs and economic benefits of the economic activities which are taking place in the region and thereby to inform policies. However, as environmental issues are very complex and underlying causes of the issues are numerous and interrelated, it requires a lot of expertise and resources to undertake a comprehensive assessment for the entire region. Therefore, this calls for greater collaboration in research (both scientific and socio-economic), among the rim countries. A network of research institutes and researchers would be required for this.

    >Most of the problems arise on land and finally end up as oceanic pollution. Terrestrial activities which creates the problems deserves much more attention in policy, research and management. IORARC is an ideal focal point to commence a programme.

    >The geo strategic significance of the Indian Ocean has been perspicuous with regard to the evolution of economies and is identified today more than ever before rising many threats. The aforesaid challenges should be critically addressed by the rim countries through extensive regional cooperation initiated by IORARC while tightening the existing national level policies in mitigating the factors contributing to those four challenges.
