NASA: sea level rising faster than the UN predicted

Recently published research indicates that sea level rise is a bigger threat to us and our coastal regions than previously thought. The latest predictions were made public by a team of Nasa-related scientists in August 2015. This is a summary of the most recent views:

  • The global estimate before the new figures was that of experts associated with the UN. In 2013 a UN panel predicted that sea levels would rise from between 0.3 and 0.9 metres by the year 2100. The latest Nasa research indicates that the lower figures are likely to be unrealistic and the higher estimates for the year 2100 are the correct ones.
  • According to a comment made to CNN by Steven Nerem, a researcher based at the University of Colorado, the planet is “locked into at least 3 feet (nearly 1 metre) of sea level rise, and probably more”.
  • The changes differ from region to region. Based on satellite data, in some areas like the US west coast, sea levels have not been rising but actually falling in recent years. Natural cycles and ocean currents are likely to be behind the phenomenon in these areas of the Pacific. Nevertheless, a substantial sea level rise may take place on the US west coast in the coming 20 years.

  • On a global scale, low-lying regions (such as Kiribati, Bangladesh, the Maldives and Florida in the US) are the most vulnerable land areas.
  • The rule of thumb is that for every centimetre of sea level rise, the sea moves 50-100 centimetres inland (source NASA).
  • The most difficult question in forecasting is determining at what rate the polar ice sheets will melt when temperatures on the planet go up.
  • Approximately one-third of the sea level rise is due to the thinning and loss of the Greenland and Antarctic ice sheets, another third is caused by the expansion of ocean water, and the remaining third is a consequence of the melting of mountain glaciers.
  • The latest data, gathered by satellites, reveal that sea levels have risen nearly 7.5 centimetres since 1992.

Oceans and coasts, a key component on the new UN agenda for sustainable development

Transforming our world, the 2030 agenda for sustainable development (advance unedited version) was published by the UN in August 2015. In chapter 14, the document highlights important marine and coastal management topics. The following is a direct citation from the new agenda. This is what is needed for sustainable management of oceans, seas, coasts and marine resources in the coming years:

Goal 14. Conserve and sustainably use the oceans, seas and marine resources for sustainable development

14.1 By 2025, prevent and significantly reduce marine pollution of all kinds, in particular from land-based activities, including marine debris and nutrient pollution

14.2 By 2020, sustainably manage and protect marine and coastal ecosystems to avoid significant adverse impacts, including by strengthening their resilience, and take action for their restoration in order to achieve healthy and productive oceans

14.3 Minimize and address the impacts of ocean acidification, including through enhanced scientific cooperation at all levels

14.4 By 2020, effectively regulate harvesting and end overfishing, illegal, unreported and unregulated fishing and destructive fishing practices and implement science-based management plans, in order to restore fish stocks in the shortest time feasible, at least to levels that can produce maximum sustainable yield as determined by their biological characteristics

14.5 By 2020, conserve at least 10 per cent of coastal and marine areas, consistent with national and international law and based on the best available scientific information

14.6 By 2020, prohibit certain forms of fisheries subsidies which contribute to overcapacity and overfishing, eliminate subsidies that contribute to illegal, unreported and unregulated fishing and refrain from introducing new such subsidies, recognizing that appropriate and effective special and differential treatment for developing and least developed countries should be an integral part of the World Trade Organization fisheries subsidies negotiation (taking into account ongoing World Trade Organization negotiations, the Doha Development Agenda and the Hong Kong ministerial mandate)

14.7 By 2030, increase the economic benefits to Small Island developing States and least developed countries from the sustainable use of marine resources, including through sustainable management of fisheries, aquaculture and tourism

14.a Increase scientific knowledge, develop research capacity and transfer marine technology, taking into account the Intergovernmental Oceanographic Commission Criteria and Guidelines on the Transfer of Marine Technology, in order to improve ocean health and to enhance the contribution of marine biodiversity to the development of developing countries, in particular small island developing States and least developed countries

14.b Provide access for small-scale artisanal fishers to marine resources and markets

14.c Enhance the conservation and sustainable use of oceans and their resources by implementing international law as reflected in UNCLOS, which provides the legal framework for the conservation and sustainable use of oceans and their resources, as recalled in paragraph 158 of The Future We Want

Microplastic pollution – a serious threat to marine ecosystems

Text and photos copyright (c) 2013 Erkki “Eric” Siirila, all rights reserved

Pioneering research has shown that plastic waste entering the ocean may have more serious negative effects on marine life than what was previously thought. Two studies published in Current Biology focus on the ecosystem effects of microplastic fragments less than 1 mm in diameter. The very small pieces of plastic have been polluting the ocean for about half a century.

Previous research has concentrated on the effects of bigger plastic objects in the marine ecosystem. This time the focus is on the fragments, which are produced for example as a result of gradual breakdown of plastic bottles in nature.

The tiny plastic particles are so small that wastewater treatment plants cannot stop them from entering the sea. A serious challenge for waste management is that this pollution does not originate only in what we normally consider plastic. The sources include synthetic textiles e.g. polyester – many of our clothes release a high number of microscopic pieces of plastic fibre when they are washed. Microbeads from cosmetic facial scrubs are one more source of harmful plastic particles. On the shores and in the sea, the microscopic plastic waste sinks into the sediments in high concentrations.

An additional problem with microplastics is that, in addition to the direct effects, they transfer harmful chemicals to marine organisms eating them. This was shown to take place in the case of lugworms by Mark Browne and his colleagues (link to Abstract). Lugworms (Wikipedia Lugworm) are an example of a common North Atlantic species using the sediments as food source. Starfish and sea cucumbers have similar feeding strategies. Mark Browne’s work was completed at Plymouth University, UK.

The harmful substances within the microplastics include antimicrobials, hydrocarbons and flame retardants, which are often persistent and may reduce health and biodiversity. Furthermore, minute plastic particles concentrate substances from the surrounding water on their surface: to name two examples, detergents and pesticides can be detected. The chemicals may be carried over to the next predators in the food chain – lugworms are eaten by flounders and wading birds. The harmful substances could also accumulate in the top predators, perhaps even in us humans. If lugworms are seriously affected, as they are, the whole food chain could be subject to significant adverse effects.

In the study by Stephanie Wright, University of Exeter, UK, and her colleagues, it was found that those lugworms which (in laboratory tanks) were subject to varying levels of plastic contamination, gained less weight than the worms in a clean environment. Consequently, the worms suffering from the consequences of plastic pollution had less energy for growth and reproduction. The worms were also likely to be less efficient in their important ecosystem service, i.e. in eating and keeping the sediments healthy and oxygenated for other animals. The article by Wright et al. is here: .

When interviewed by the BBC, Dr Browne summarised his earlier findings relating to 18 sediment samples from the beaches in several countries: “We found that there was no sample from around the world that did not contain pieces of microplastic.”

Based on these two ground-breaking articles in Current Biology, there seems to be an urgent need to develop the use practices and waste management techniques of plastic products in our societies. This is an important coastal and marine conservation issue.

In addition to the material published in Current Biology, summaries published by the British BBC and The Guardian, were helpful in the preparation of this Coastal Challenges’ article.


Ocean state alarming – policy changes are needed

Urgent measures are needed to stop ocean degradation related to climate change. The speed and negative effects are greater and more clearly felt that previously thought. These are the most important conclusions of recent work by an international marine scientist panel.

The results of the latest wide-ranging international review were made public by the World Conservation Union (IUCN) at the beginning of October 2013. Behind the work were the experts of IUCN and International Programme of the State of the Ocean (IPSO). The outcomes have also been published in the scientific journal Marine Pollution Bulletin.

Evening in the South Atlantic.

An IUCN press release highlights the contents by telling us the following preoccupying facts: The ocean is absorbing much of the global warming. Unforeseen levels of carbon dioxide are bound by the ocean. The cumulative impact of this, together with other ocean stressors, is much more threatening than past estimates.

The other contributing stressors include decreasing oxygen levels in the sea and runoff of nitrogen from land. Also chemical pollution and serious overfishing are hampering the ocean’s capacity to act as a balancing factor in what is called “carbon preturbations”.

A comment by Professor Alex Rogers of Somerville College, Oxford (also Scientific Director of IPSO) is cited in the IUCN summary paper: “The health of the ocean is spiraling downwards far more rapidly than we had thought. We are seeing greater change, happening faster, and the effects are more imminent than previously anticipated. The situation should be of the gravest concern to everyone since everyone will be affected by changes in the ability of the ocean to support life on Earth.”

Professor Dan Laffoley, from IUCN, commented the new interdisciplinary findings by saying: “What these latest reports make absolutely clear is that deferring action will increase costs in the future and lead to even greater, perhaps irreversible, losses. The UN climate report confirmed that the ocean is bearing the brunt of human-induced changes to our planet. These findings give us more cause for alarm – but also a roadmap for action. We must use it.“

More in depth, the foreseen challenges and problems include the following:

Oxygen levels in the ocean are expected to decline between 1% and 7% by 2100.  Tropical  oceans and and the North Pacific have had a trend of decreasing oxygen levels during the past 50 years and this will continue because of global warming. In addition, lack of oxygen will be a serious problem in coastal seas commonly affected by eutrophication (sewage and agricultural runoff being the main reasons).

In case CO2 release by us planet Earth inhabitants continues at the current level, acidification of sea water will be a major factor affecting ocean life, marine food production and coastal protection. Acidification would be felt for example on coral reefs, where erosion in the near future could exceed reef formation (calcification). This in turn would degrade the reef habitat and result in the destruction of the natural breakwaters formed by corals – a serious consideration in coastal regions commonly hit by heavy storms.

As to the direct physical and geochemical consequences of global warming in the ocean by 2050, they include: reduced seasonal ice zones, increasing stratification (separation) of ocean layers leading to oxygen depletion, increased venting of methane from the bottom of the Arctic Sea, and more common low oxygen -events in the oceans.

Around the globe, fisheries management is still unable to stop overfishing. The decline of key species and damage to the ecosystems where the fish stock live continue. All this undermines the resilience of the oceans.

Urgent measures proposed by IPSO and IUCN include:

Reduction of global CO2 emissions to keep temperature rise in less than 2 degrees C.

Implementation of community- and ecosystem-based management and favouring small-scale fisheries. Harmful fisheries’ subsidies resulting in overcapacity would need to be eliminated. In addition, vulnerable ecosystems would need an increased level of protection. Finally, illegal, unreported and unregulated fishing would need to to be combated.

Development of a more relevant global infrastructure for high-seas ocean governance is necessary. Especially a new implementing agreement for the conservation and sustainable use of biodiversity in areas beyond national jurisdiction is needed (within the United Nations Law of the Sea – UNCLOS – framework).

UN Conference on Sustainable Development: highlights of the Rio+20 final document

At the UN Conference on Sustainable Development in Rio (June 2012), binding new international agreements were not agreed upon, which was disappointing. Nevertheless, the final document is worth summarising in order to highlight the most important common views of the world´s governments as regards sustainable development and the marine environment. Luckily, in the management of seas and oceans important progress was achieved. The following is a summary – with special reference to coasts, seas and oceansof  the final document “The Future We Want”:

The document states that for sound development in general, holistic, integrated and sustainable management of natural resources needs to be promoted. At the same time, economic, social and human development should be supported.  Also, the international community is asked to move the sustainable development agenda forward, through the achievement of internationally agreed goals including the existing Millennium Development Goals. Green economy in the context of sustainable development and poverty eradication is mentioned as one of the important tools available for achieving sustainable development.

The Rio participants recognise the key role that improving energy efficiency plays. This includes the increasing share of renewable energy and cleaner, more energy-efficient technologies. Climate change as a persistent crisis is acknowledged: the global nature of climate change calls for the widest possible cooperation by all countries and their participation in an effective international response. Naturally, reduction of greenhouse gas emissions is needed. Also the related urgent needs of Small Island Developing States (SIDS) are mentioned in the final document.

The need for effective, transparent, accountable and democratic natural resources´ management institutions is mentioned in the document. So is the need for contributions towards sustainable development by both the public/private sectors and the scientific/technological communities. We are also reminded of the important role of citizens at the grass-root level, e.g. fishers, in the development of production activities which are environmentally more sound. The valuable contributions by  NGOs in promoting sustainable development are acknowledged.

The establishment of UNEP as a permanent UN organisation (instead of being a non-permanent programme) was not achieved, but it was decided that UNEP would be strengthened. In addition, the participants decided to establish an intergovernmental high-level political forum replacing the current UN Commission on Sustainable Development.

In the final document, the participating states recognise the severity of global biodiversity loss and degradation of ecosystems: this underlines the importance of biodiversity conservation, enhancing habitat connectivity and building ecosystem resilience.

In the Oceans and Seas chapter of The Future We Want, important progress can be observed. To begin with, the participating states commit to protect and restore the health, productivity and resilience of oceans and marine ecosystems, and to maintain their biodiversity for the conservation / sustainable use by the present and future generations. Furthermore, the participants agree to apply an ecosystem approach and the precautionary principle in marine management.

The Rio conference delegations recognise the importance of UNCLOS (Law of the Sea) in advancing sustainable development and they emphasise the need for cooperation in marine scientific research. The states also support the Regular Process for Global Reporting and Assessment of the State of the Marine Environment (established under the UN General Assembly) and look forward to the completion of its first global integrated assessment by 2014.

In the seas and oceans chapter, the importance of the conservation / sustainable use of marine biodiversity beyond areas of national jurisdiction is recognised. Building on the work of an international working group (and before the end of the 69th Session of the United Nations General Assembly) the Rio participants commit to address this issue on an urgent basis.

The states also note with concern that the health of the oceans and marine biodiversity are negatively affected by marine pollution. The final document mentions marine debris, plastic, persistent organic pollutants, heavy metals, and nitrogen-based compounds. The sources mentioned include marine and land-based sources, including shipping and land runoff. The participants commit to take action to reduce the incidence and impacts of such pollution on marine ecosystems. The relevant measures would include implementation of IMO conventions and the follow-up of relevant initiatives such as the Global Programme of Action for the Protection of the Marine Environment from Land-based Activities. With the help of scientific assessments, the states further commit to take action to significantly reduce marine debris by 2025.

In the seas and oceans chapter the participants note the significant threat which alien invasive species pose to marine ecosystems, and commit to implement measures to prevent their introduction. The management of the adverse environmental impacts will be improved including those alien species adopted in the framework of IMO.

Sea level rise and coastal erosion are noted as serious threats for many coastal regions and islands particularly in developing countries. International action to address these challenges is called for in the final document.

The participating states also call for support to initiatives that address ocean acidification and the impacts of climate change on marine and coastal ecosystems and resources. They reiterate the need to work collectively to prevent further ocean acidification, as well as to enhance the resilience of marine ecosystems and of the communities whose livelihoods depend on them. The importance of marine scientific research, monitoring and observation of ocean acidification and of particularly vulnerable ecosystems through international cooperation are mentioned.

In the Rio final document the participating states stress their concern about the potential environmental impacts of ocean fertilization. They recall the decisions related to ocean fertilization adopted by the relevant intergovernmental bodies, and decide to continue addressing ocean fertilization with utmost caution. The precautionary approach will be applied.

In Rio the participating states promised to intensify the efforts to meet the 2015 target as to maintenance or restoring fisheries stocks to levels that can produce maximum sustainable yield on an urgent basis. The photo of the fishing vessel is from the Falkland Islands (Islas Malvinas), copyright (c) 2012 Erkki Siirila.

The Rio participants commit, on an urgent basis, to intensify the efforts to meet the 2015 target as to maintenance or restoring fisheries stocks to levels that can produce the maximum sustainable yield. The foreseen time frame is “the shortest time feasible”. To achieve this, the states commit to urgently develop and implement science-based management plans. Fisheries reduction and suspension are listed as management methods. The importance of by-catch reduction and the control of destructive fishing practices are mentioned as well as the importance of impact assessments.

Relating to UNCLOS, the Rio delegations urge states to fully implement the 1995 Agreement on the Conservation and Management of Straddling and Highly Migratory Fish Stocks. Furthermore, all States are called upon to implement the Code of Conduct for Responsible Fisheries and the corresponding FAO International Plans of Action and technical guidelines.

The final document acknowledges that illegal, unreported and unregulated (IUU) fishing deprives many countries of a crucial natural resource and remains a persistent threat to their sustainable development. A recommitment to eliminate IUU fishing is presented. Reference is made to the Johannesburg Plan of Implementation which aims at preventing and combating these practices in the following ways: a) by implementing national and regional action plans in accordance with FAO’s international IUU combat plan, b) by identifying vessels engaged in IUU fishing, c) by depriving offenders of the benefits accruing from IUU fishing, and d) by cooperating with developing countries to systematically identify needs and build capacity (monitoring, control, surveillance, compliance and enforcement systems).

The Rio delegations recognise the need for transparency and accountability in fisheries management by regional fisheries management organizations (RFMOs). The efforts already made by those RFMOs that have undertaken independent performance reviews are recognised. A call is presented on all RFMOs to regularly undertake such reviews, publish the results and implement the recommendations.

Furthermore, the Rio final document reaffirms the Johannesburg Plan of Implementation as to elimination of subsidies that contribute to illegal, unreported, and unregulated fishing and overcapacity, mentioning the importance of this sector to developing countries. Reference is made to the WTO Doha Development Agenda and the Hong Kong Ministerial mandates for more vigorous control of fisheries subsidies. Prohibition of subsidies that contribute to overcapacity and over-fishing is mentioned as a control measure. States are also encouraged to eliminate subsidies that contribute to overcapacity and over-fishing, to refrain from introducing new such subsidies and to refrain from extending or enhancing existing subsidies.

A commitment to ensure access to fisheries and corresponding markets by fishers (subsistence, small-scale, artisanal) and women fish workers and indigenous peoples is also presented, highlighting the needs of these communities in developing countries and small island developing states.

The importance of coral reef conservation and marine protected areas is highlighted in the final document of the Rio conference on sustainable development. Image from a Red Sea coral reef in Egypt, photo copyright (c) 2012 Erkki Siirila.

As to coral reefs and mangroves, the Rio delegations recognise the significant economic, social and environmental contributions of coral reefs, in particular to islands and other coastal states, as well as the significant vulnerability of the reefs and mangroves to impacts including from climate change, ocean acidification, overfishing, destructive fishing practices and pollution. Support for international cooperation is expressed in order to conserve coral reef and mangrove ecosystems and to realise their social, economic and environmental benefits. Facilitation of technical collaboration and voluntary information sharing are mentioned as supporting measures. Surprisingly, sea grass beds are not separately mentioned in the Rio final document. (The importance of healthy sea grass beds as carbon sinks in fighting global climate change has recently been acknowledged by the marine science research community).

In the seas and oceans chapter of The Future We Want, the delegations reaffirm the importance of area-based conservation measures, including marine protected areas, consistent with international law and based on best available scientific information. The participants note decision X/2 of the 10th Meeting of the Conference of the Parties to the Convention on Biological Diversity, that by 2020, 10 percent of coastal and marine areas, especially areas of particular importance for biodiversity and ecosystem services, are to be conserved through effectively and equitably managed, ecologically representative and well-connected systems of protected areas and other effective area-based conservation measures.

Finally, it may be considered surprising that the importance of managing the sea-land interface as a special area was not mentioned in The Future We Want. As the coastal zone is an area of many opportunities, user conflicts, resource degradation and lost opportunities, it would have been natural to say something in the Rio final document about the need for integrated coastal zone management.

Integrated coastal zone management: a specialist highlights the needs, benefits and techniques

Dr. Peter R. Burbridge is a well-known advocate of integrated coastal zone management (ICZM). In a recent Coastal Challenges interview he explained what integrated coastal management is and why it is needed. Here are some of the comments made by Dr. Burbridge, Emeritus Professor of the University of Newcastle upon Tyne in the U.K.:

“The development challenges facing humanity are most complex in the coastal regions. Why? Partly because the richness and diversity of the coastal resources’ opportunities to support economic and social development are much greater than in the terrestrial environment or the purely marine environment. It is that interface between the sea and the land where we find the most complex, the most rich and the most diverse forms of natural resources. And they sustain many different forms of economic development. And that means that there is much competition for access to and often exclusive use of the coastal area and coastal resources. Now, the challenge we face as managers is trying to maximise the potential use of these resources without damaging the very resource base which creates those resources in the first place.”

“You need integration in the sense that there are different economic and social groups wanting to have access to the coast. And what you have to do is to try to treat them equitably, so that everybody has an equal chance of access to the resource but without damaging the resource for other people to enjoy and use in effective ways.  And that means that you have to get the different economic sectors to try to coordinate their activities so that they don´t disrupt the potential flow of benefits from the coast – without destroying the natural systems. And that’s the challenge. And that’s why we talk about integration. It is integration of different economic sectors, different social demands from the coast and different political systems trying to coordinate the development process more effectively.  We are talking about development planning here. We are not talking about environmental conservation. The environmental conservation is one tool to manage the natural systems.”

“Integrated coastal management is a set of principles to guide development planning. It is meant to create a working environment where people see that there are ways of doing things that are less environmentally damaging and more economically responsible, and create a greater social benefit. And that’s difficult, to get people to think of the environment, the economy and social aspects in the same sentence. And that’s what coastal management is trying to do. We are not purely trying to protect the environment, we are not trying to maximise the economic activities at the cost of social equity.”

“One of the problems we have is getting any political system to understand how complex the coastal resource pressures are, but also the great value of the coast, the strategic value of the coast in meeting social and economic pressures. And those pressures have to be managed. And the economic rationale behind that is that you can get greater social and  economic benefits by wise management than you can by totally unregulated free-for-all development. And that’s the challenge, this convincing people that the strategic value of the coast is important enough to invest in managing the coast effectively.”

The interview (“Dr. Peter Burbridge and Integrated Coastal Zone Management” on Youtube) addresses more coastal management topics than those mentioned above. Here is the direct Youtube link:

Coastal zone of Chile: ten management recommendations

Chile is a country with thousands of kilometres of coastline (the exact length of the coast depends on the definition applied). Naturally, moving towards integrated coastal zone management benefits a country like that.

The Coastal Challenges editor did a consultancy in the Fourth Region (Coquimbo Region) of Chile a few years ago. One of the results was a set of general guidelines for integrated coastal management in that region. In the ten conclusions/recommendations the local experiences were combined with the lessons learned in coastal management internationally.

A powerful tsunami in 2010 made Chileans aware of the need for sound coastal management. This Chilean government fax indicating there was a tsunami risk was not enough to result in massive coastal evacuations. As a result, lots of human lives were lost.

The conclusions and recommendations for integrated management of the Coquimbo coastal area are listed below:

  1. Integrated management of the coastal zone is a learning process with incremental implementation, feedback and adjustment mechanisms.
  2. At all levels of action, it is important to build the integrated management on a sustainable  financial and economic base, for example through self-funding.
  3. It is important to incorporate in the process the opinions of all the involved and interested parties, for example by applying conflict resolution mechanisms.
  4. It is essential that the actions keep focus on just a few issues which are understood by all the participants in the process. The focus on the issues means that an exact definition of the coastal zone is not a precondition for the action to begin.
  5. In general, construction on the local institutional roots is the safest option. E.g. the existing management systems, which are politically supported, can be modified instead of building totally new management institutions. Also in this case, the application of innovative ideas for real integration is important.
  6. A long-term vision is essential, and as part of this, opportunities should be left open for the future generations.
  7. The management should be based on good knowledge of the laws of nature. Implementation would need to be proactive instead of retroactive.
  8. It is important that the decision-making system is just and efficient.
  9. It is essential to understand that combining sustainable management with the poverty of resource users is difficult. Because of this, development of economic alternatives for the least favoured groups is needed.
  10. In sustainable coastal zone management, integration mechanisms are only one element. Specific action is needed also in the management of key species and habitats, pollution control, land use planning and environmental impact assessment. In addition to integration, sectoral activities in these and other action fields need to continue. (Naturally, sector-specific work needs to go on, but the sectoral actions should no more be implemented in isolation from other coastal zone activities.)
