SANTIAGO, Oct 12 2022 (IPS)

In Magallanes, Chile’s southernmost region, doubts and questions are being raised about the environmental impact of turning this area into the world’s leading producer of green hydrogen.

The projects require thousands of wind turbines, several desalination plants, new ports, docks, roads and hundreds of technicians and workers, with major social, cultural, economic and even visual impacts."The scale of production creates uncertainties, heightened because there is no baseline. The question is whether Chile currently has the capacity to carry out large-scale green hydrogen projects.” -- Jorge Gibbons

This long narrow South American country of 19.5 million people sandwiched between the Andes Mountains and the Pacific Ocean has enormous solar and wind energy potential in its Atacama Desert and southern pampas grasslands. This has led to a steady increase in electricity generation from clean and renewable sources.

In 2013, only six percent of the country’s total electricity generation came from non-conventional renewable sources (NCREs) – a proportion that climbed to 32 percent this year. Installed NCRE capacity in September reached 13,405 MW, representing 40.7 percent of the total. Of the NCREs, solar energy represents 23.5 percent and wind power 12.6 percent.

In Chile, NCREs are defined as wind, small hydropower plants )up to 20 MW), biomass, biogas, geothermal, solar and ocean energy.

According to the authorities, the wind potential of Magallanes could meet 13 percent of the world’s demand for green hydrogen, with a potential of 126 GW.

Green hydrogen is generated by low-emission renewable energies in the electrolysis of water (H2O) by breaking down the molecules into oxygen (O2) and hydrogen (H2). It currently accounts for less than one percent of the world’s energy.

However, it is projected as the energy source with the most promising future to advance towards the decarbonization of the economy and the replacement of hydrocarbons, due to its potential in electricity-intensive industries, such as steel and cement, or in air and maritime transportation.

The National Green Hydrogen Strategy, launched in November 2021 by the second government of then right-wing President Sebastián Piñera (2018-2022), seeks to increase carbon neutrality, decrease Chile’s dependence on oil and turn this country into an energy exporter.

The government of his successor, leftist President Gabriel Boric, in office since March, created an Interministerial Council of the Green Hydrogen Industry Development Committee, with the participation of eight cabinet ministers.

A spokesperson from the Ministry of Energy told IPS that “this committee has agreed to bring forward, from 2025 to 2022, the update of the National Green Hydrogen Strategy and the new schedule for the allocation of state-owned land for these projects.”

“We will promote green hydrogen in a cross-cutting manner, with an emphasis on harmonious, fair and balanced local development. By bringing forward the update of the strategy, we seek to generate certainty for investors and to begin to create the necessary regulatory framework for the growth of this industry in our country,” he said.

In the area known as Cabo Negro, in the Chilean region of Magallanes, several companies have installed wind turbines to generate wind energy.

Warnings from environmentalists

In a letter to the president, more than 80 environmentalists warned of the risk of turning “Magallanes y La Antarctica Chilena” – the region’s official name – into an environmental sacrifice zone for the development of green hydrogen.

“The energy transition cannot mean the sacrifice of migratory routes of birds that are in danger of extinction, otherwise it would not be a fair or sustainable transition,” said the letter, which has not yet received a formal response.

Environmentalists argue that the impact is not restricted to birds, but also affects whales that breed there, due to the effects of desalination plants, large ports and harbors.

Carmen Espoz, dean of science at the Santo Tomás University, who signed the letter, told IPS that “the main warning that we have tried to raise with the government, and with some of the companies with which we have spoken, is that there is a need for zoning or land-use planning, which does not exist to date, and for independent, quality baseline information for decision-making” on the issue.

Espoz, who also heads the Bahía Lomas Center in Magallanes, based in Punta Arenas, the regional capital, clarified that they are not opposed to the production of green hydrogen but demand that it be done right.

It is urgently necessary, she said in an interview in Santiago, to “stop making decisions at the central level without consultation or real participation of the local communities and to generate the necessary technical information base.”

The signatories asked Boric to create a Regional Land Use Plan with Strategic Environmental Assessment to avoid unregulated development of projects.

“We are not only talking about birds, but also about profound social, cultural and environmental impacts,” said Espoz, who argued that the model promoted by the government and green hydrogen developers “does not have a social license to implement it.”

The bird question

Prior to this letter to Boric, the international scientific journal Science published a study by Chilean scientists warning about potential impacts of wind turbines on the 40 to 60 species of migratory birds that visit Magallanes.

“It is estimated that the installation of wind turbines along the migratory paths of birds could affect migratory shorebird populations, which is especially critical in the cases of the Red Knot (Calidris canutus rufa) and the Magellanic Plover (Pluvianellus socialis),” said Espoz.

Both species, she said, “are endangered, as is the Ruddy-headed Goose (Chloephaga rubidiceps).”

She added that if 13 percent of the world’s green hydrogen is to be generated in southern Chile, some 2,900 wind turbines will have to be installed by 2027, “which could cause between 1,740 and 5,220 collisions with bird per year.”

Jorge Gibbons, a marine biologist at the University of Magallanes, based in Punta Arenas, said the big problem is that Magallanes does not have a baseline for environmental issues.

“The scale of production creates uncertainties, heightened because there is no baseline. The question is whether Chile currently has the capacity to carry out large-scale green hydrogen projects,” he told IPS from the capital of Magallanes.

Gibbons believes it would take about two years to update the data on the dolphin and Southern Right Whale (Eubalaena australis) populations

“The greatest risks to dolphins will be seen in the Strait of Magellan. I am talking about Commerson’s Dolphins (Cephalorhynchus commersonii), which are only found there in Chile and whose population is relatively small,” he said.

He proposed studying the route to ports and harbors of these species and to analyze how they breed and feed.

“The issue is how noise disturbs them or interrupts their routes. These questions are still unanswered, but we know some things because it is the best censused species in Chile,” he explained.

According to Gibbons, the letter to Boric is timely and will help reduce uncertainty because “the process is just beginning and the scientific and local community are now wondering if the plan will be well done.”

Conflict of interests

The partnership between HIF Chile and Enel Green Power Chile withdrew from the Environmental Evaluation System the study of the Faro del Sur Wind Farm project, involving an investment of 500 million dollars for the installation of 65 three-blade wind turbines on 3,791 hectares of land in Magallanes.

The study was presented in early August with the announcement that it was “a decisive step for the future of green hydrogen-based eFuels.”

But on Oct. 6, its withdrawal was announced after a series of observations were issued by the Magallanes regional Secretariat of the Environment.

“The observations of some public bodies in the evaluation process of this wind farm exceed the usual standards,” the consortium formed by the Chilean company HIF and the subsidiary of the Italian transnational Enel claimed in a statement.

The companies argued that “the authorities must provide clear guidelines to the companies on the expectations for regional development, safeguarding the communities and the environment.

“In light of these exceptional requirements, it is necessary to understand which requirements can be incorporated and which definitely make projects of this type unfeasible in the region,” they complained.

The government reacted by stating that it is important to remember that Faro del Sur is the first green hydrogen project submitted to the environmental assessment process in Magallanes.

“During the process, some evaluating entities made observations on the project, so the owners decided to withdraw it early, which does not prevent them from reintroducing it when they deem it convenient,” the Ministry of Energy spokesperson told IPS.

He added that the ministry stresses “the conviction to develop the green hydrogen industry in the country and that this means sending out signals, but in no case should this compromise environmental standards and citizen participation in the evaluation processes.”

Climate change is one of the greatest risks to human societies, but also to biodiversity, often creating a “snowball effect” exacerbating existing pressures such as habitat fragmentation.

Consequently, the conservation community, including inter-governmental treaties such as AEWA and NGOs such as BirdLife International, is strongly advocating genuine attempts to address its causes and mitigate its effects. We can square this particular circle: producing renewable energy to help combat climate change without inadvertently hammering another nail in the coffin of our endangered wildlife.

Alongside cutting energy demand and increasing energy efficiency, developing renewable sources of energy is essential in order to reduce the amount of fossil fuels burned and the emission of greenhouse gases. There is little doubt that the development and deployment of renewable energies are vital if we are to end our dependency on traditional fuels.

However, appropriate planning, assessment and monitoring of renewable infrastructure are necessary in order to prevent adverse effects to wildlife.  All the innovative technologies being developed – wind turbines, solar panels, tidal, wave and hydropower – can have distinct drawbacks as far as wild animals – and particularly migratory birds – are concerned, if not sited correctly.

One thing that conventional and renewable energies often have in common is the need to transfer power from the point of production to the consumers.  Natural habitat is sacrificed so that power lines can be constructed.

The pylons and cables form a barrier to migration – and large birds are most vulnerable – perching on the structures, their long wing span can often lead to short circuits; this is fatal to the electrocuted bird but also inconvenient for the customer whose electricity supply is interrupted. The birds that most commonly fall victim are from long-lived, slow-breeding species that cannot sustain these losses.

Power lines are not the only hazard – wind turbines take a toll too.  The Spanish Ornithological Society says that more than 18,000 wind turbines in Spain are causing significant mortality of raptors and bats, including threatened species.

It would be foolish for conservationists to oppose all forms of renewable energy just as it would be foolish to welcome any proposal to build a windfarm, barrage or solar plant unquestioningly.  What needs to be done is to find the right balance.

The Parties to the Convention on the Conservation of Migratory Species of Wild Animals (CMS), under which AEWA was concluded, adopted a resolution calling for appropriate Strategic Environment Assessments and Environmental Impact Assessments procedures to be put in place, which would mean applying rigorous planning guidance.

It would involve following a simple sequence: first, developments should be avoided in the most sensitive locations, e.g. bottlenecks on birds’ migration routes.  Everywhere else, mitigation measures should be taken and a last resort compensatory actions should be considered.

And some mitigation measures bring large gains at little cost– shutting off wind farms when migrating birds are passing has proven to have reduced the mortality rate of the Griffon Vulture by 50 percent in Spain – while lost electricity production was less than 1.0 percent.

The design and placement of the pylons are also very important – in forested landscapes for example, it is best if the structures do not protrude above the canopy.  Monitoring in France over the past 20 years has shown that attaching spirals to power lines at regular intervals to make them more visible can lead to a reduction in the fatalities as a result of collisions.

The next few decades will see a massive increase in demand for power in developing countries in Africa – and this will be matched by expansion of both renewable generation capacity and grid connections.  The danger is that if the design and location are not right, further devastating losses to the continent’s birdlife will be inevitable.

We need to increase our knowledge and to share it once it has been acquired.  This will entail close cooperation between conservationists on the one hand and the power companies on the other.

CMS and AEWA have produced the first version of a set of guidelines on the appropriate deployment of renewable energy technology and the BirdLife International network can provide the expertise on the ground to ensure that we can square this particular circle: producing renewable energy to help combat climate change without inadvertently hammering another nail in the coffin of our endangered wildlife.

BONN, Jan 31 2015 (IPS)

The first global treaty dealing with biodiversity was the Ramsar Convention – predating the Rio processes by 20 years.

Ramsar aims to conserve wetlands, the usefulness of which has been undervalued – even the eminent French naturalist of the 18^th century, the Comte de Buffon, advocated their destruction – and which have suffered large losses in recent decades.Wetlands are vital for birds – and especially waterbirds – but it is also the case that the birds are vital to the wetlands, playing a major role in maintaining nature’s balance.

Far from being wastelands, wetlands provide invaluable services, replenishing aquifers that supply drinking water and filtering out harmful pollutants. By maintaining a healthy environment, wetlands help ensure human well-being.

While the Ramsar Convention has had to deal with a broader spectrum of wetland issues over the years, it should be remembered that its full title includes “especially as waterfowl habitat”, and in AEWA, Ramsar has a strong ally with a clear focus on waterbird conservation in the African-Eurasian Flyway.

The areas designated as Ramsar Sites form an important part of the network of breeding, feeding and stopover grounds that are indispensable to the survival of the 255 bird populations of listed under AEWA.

Ramsar Sites are vital “hubs” in the network of habitats that constitute the African-Eurasian flyway along which millions of birds migrate in the course of the annual cycle. They include habitats as diverse as the Wadden Sea in Europe and the Banc d’Arguin in Mauritania, both also designated as UNESCO World Heritage Sites and important staging posts for birds migrating between Arctic breeding grounds and wintering sites deep in Africa.

Despite being often far apart geographically and different morphologically, these sites are inextricably linked by the birds that frequent them.

The definition of “wetland” extends to fish ponds, rice paddies, saltpans and some shallow marine waters, so Ramsar has sites of significance to other species covered by the Convention of Migratory Species, under which AEWA was concluded.

Examples are the Franciscana dolphin (the only dolphin species to inhabit wetlands) found in the estuary of the River Plate and along the coast of South America; and the European eel – a recent addition to the CMS listings – which spends most of its life in rivers but spawns and then dies in the Sargasso Sea.

But it is waterbirds that have the strongest links to wetlands and the future of many species is in doubt as a result of the continuing reduction in area of these most productive of habitats. Of great concern is the fate of the mudflats of the Yellow Sea which are under increasing pressure from human developments because tied to them is the fate of a number of threatened shorebirds.

Lake Natron in the United Republic of Tanzania is the only regular breeding site of over two million Lesser flamingoes. Applications have been made to exploit the area’s deposits of soda ash leading to fears that irrevocable damage would be done to the site resulting in the species’ extinction.

The habitats of Andean flamingoes – the Puna and Andean Flamingoes – are facing similar problems as illegal mining activities have eroded the nesting sites and contaminated the water, exacerbating other threats such as egg collection.

Fragile wetland ecosystems also fall victim to man-made accidents – the explosion of the Deepwater Horizon oil platform in the Gulf of Mexico and the Sandoz chemical works fire in Basel, Switzerland in 1986 being just two examples of countless incidents, both leading to the death of thousands of birds and fish.

Wetlands are vital for birds – and especially waterbirds – but it is also the case that the birds are vital to the wetlands, playing a major role in maintaining nature’s balance.

Government representatives will gather in Paris later this year in the latest effort to seek agreement on the steps necessary to arrest the causes of climate change. Wildlife is already feeling the effects and one of the best ways to ensure that animals can adapt is to ensure that there are enough robust sites providing the habitat and food sources at the right time and in the right place.

The theme chosen by the Ramsar Convention for this year’s campaign is Wetlands for Our Future and there is a particular emphasis being placed on the role of young people. While wetlands are of course vital for humans, they are no less important for the survival of wildlife and to a great extent also depend on the birds that live in them.

It is the role of AEWA to provide a forum where the countries of Europe, West Asia and Africa can work together to maintain the network of sites making up the African-Eurasian flyway.

So great are the contrasts between the frozen empty expanses of the far north and Africa’s baking deserts, steamy rain forests and savannahs that any direct connections between the two seem far-fetched – if they indeed exist at all.

In fact, migratory birds provide an environmental tie linking the Arctic and Africa and are the reason why the U.N. Agreement on the Conservation of African-Eurasian Migratory Waterbirds (AEWA) and the Conservation of Arctic Flora and Fauna (CAFF), the biodiversity working group of the Arctic Council, have entered a commitment to cooperate.

The Arctic Council is holding its first Arctic Biodiversity Congress in Trondheim, Norway and far from being of marginal interest to AEWA, its deliberations over the fauna inhabiting the regions around the North Pole could hardly be more relevant.

Following publication of the Arctic Biodiversity Assessment in May 2013, progress is being made in elaborating a strategy under the Arctic Migratory Birds Initiative (AMBI): a concrete example of where we can collaborate with practical work on the ground.

The habitats could hardly be more different and the distances between them are large, but the waterfowl, shorebird and seabird species – the predominant birds of the Arctic – find the conditions they require at different times of the year in the various habitats of the world.

The birds have adapted to develop the capacity to make their often arduous journeys from their Arctic breeding grounds to wintering sites and back. These wintering sites can be in Europe – but in some cases they even lie as far as in Southern Africa, as is the case for the Red Knot.

Approximately 200 bird species spend time every year in the Arctic, but for many the Arctic provides their only principal breeding site. Of the 255 species and populations covered by AEWA, a large proportion breeds in the far north but heads south in search of more plentiful food or milder weather.

Two of the most seriously threatened species listed under AEWA – the Lesser White-fronted Goose and the Red-breasted Goose – breed in the Arctic.The habitats could hardly be more different and the distances between them are large, but the waterfowl, shorebird and seabird species - the predominant birds of the Arctic - find the conditions they require at different times of the year in the various habitats of the world.

The conditions ideal for breeding waterfowl are too hostile for all but the hardiest of people. This has been a blessing for the animals concerned, as limited human interference has left their habitats relatively unscathed by the encroachments witnessed in other regions, with higher – and growing – numbers of people, converting land to agriculture, building towns and exploiting natural resources.

The Arctic’s human inhabitants have always had a deep respect for nature – its bounty, beauty, and balance. One problem the Arctic does not face is the indifference of its indigenous peoples. Newcomers, however, can be a different matter.

Warmer temperatures have opened the region to oil and gas exploration and sea channels are becoming navigable. This increases not only the risks of pollution, but also human presence, affecting the delicate balance that has persisted for centuries.

The unique and harsh climate of the Arctic makes it difficult for exotic species to gain a foothold, although the range of some is creeping northwards as temperatures rise. For example, the Red Fox is displacing its Arctic cousin by outcompeting it as a predator, which might yet prove to have serious consequences for its prey.

This is just one of the effects of climate change, but this, combined with the rate and extent of thawing tundra, melting sea-ice and phenological changes are leading to unpredictable consequences in the region. It is folly to imagine that climatic disruptions on other continents have no repercussions closer to home.

Despite the apparent lack of geographic connection, the AEWA African Initiative endorsed at the last Meeting of the Parties in La Rochelle in 2012 and AMBI are in fact ideal partners, acting as a bridge spanning the geographic divide and facilitating the international cooperation so fundamental to the conservation of migratory species.

Nature conservation and the sustainable use of wildlife are areas of policy that need the support and commitment of local communities if viable solutions are to be found and implemented effectively.

Lessons learned in one region can be adapted for application in others, and the way local communities in the Arctic manage and sustainably use their wildlife resources provides examples that could prove to be models that others might wish to follow. Migratory birds are often called the ambassadors of biodiversity, because they provide the link between sites that, on first glance, have little in common but on closer examination share so much.

When the great navigators of old sailed into uncharted waters, they began to realise how large the world was. It has taken the age of satellite communication and jet airliners to make us realise just how small it is; something the birds have known for millennia.

By Ranjit Devraj
NEW DELHI, Aug 22 2013 (IPS)

Every winter the Okhla wetlands, a charmed haven in the heart of India’s bustling capital city, play host to Greater Flamingoes, Greylag Geese, Tufted Pochards, Northern Shovelers and other exotic, feathered visitors winging in from colder climes as far away as Siberia.

These avian migrants join hundreds of local water birds to breed in the Okhla Bird Sanctuary and Wildlife Park – a four square kilometres patch of wetland on the Jamuna river. The river is struggling to survive amidst costly real estate and development projects in the state of Delhi on the west bank of the river and Uttar Pradesh state on the east.

Conservationists now warn that unless there is a halt to construction activity on the banks of the Jamuna and to the pumping of raw sewage and effluents into the river, the annual spectacle of colours and shapes winging into the Okhla sanctuary will soon be nothing more than a cherished memory.

According to Tarun Kumar Roy, coordinator of the Asian waterbird census of Wetlands International (WI), some 10,000 birds could be counted at the Okhla sanctuary a decade ago. “That number has now been reduced by half, to around 5,000 birds,” Roy told IPS.

Wetlands International, a Netherlands-based not-for-profit organisation, works to conserve wetlands and their resources for people and for the cause of biodiversity.

Roy, who has been working to get the Okhla sanctuary recognition as a site protected under the 1971 Ramsar Convention, says the dwindling bird numbers have dashed his hopes.

Other experts believe that it is still possible to gain recognition for the Okhla sanctuary as a Ramsar site so that it can benefit from international support through the treaty designed to stop encroachments on wetlands with ecological, economic, cultural, scientific and recreational significance.

“The fact that a good number of transcontinental migratory birds visit the Okhla sanctuary makes it an outstanding candidate for designation as a Ramsar site,” Faizi S. Faizi, who is a member of the expert committee on biodiversity and development at the United Nations Convention on Biological Diversity, told IPS.

Faizi says it is helpful that the Okhla sanctuary has been certified as an ‘Important Bird Area’ by Birdlife International for its ornithological importance.

Gopal Krishna, coordinator of Toxics Watch, a major environment group based in the capital, said it is up to the ministry of environment and forests to get the Okhla sanctuary rated as a Ramsar site. “If the ministry has failed in this regard it is only due to pressure from the powerful construction and real estate lobbies,” Krishna told IPS.

“It is hard to believe that the officials of the ministry are unaware of encroachments into a national sanctuary located barely five kilometres away from its offices,” said Krishna.

“How could, for example, a heavily polluting waste-to-energy incinerator come up on the edge of the park without ministry clearance?”

Krishna said the future of the Okhla sanctuary now rests greatly on a series of cases filed by environmentalists and local residents at the National Green Tribunal, a special fast-track court that handles contentious cases relating to environmental issues.

“The most important of these cases relates to the waste-to-energy incinerator that has been functioning since January 2012 within the eco-sensitive zone of the Okhla sanctuary,” said Krishna. “A judicial commission of the tribunal has established that the emissions from the plant are 25 times above the permitted limit.”

In July, the school of environmental sciences at New Delhi’s Jawaharalal Nehru University released the results of a study that found the air around Okhla to be severely polluted with lead, nickel, cadmium and cobalt that could only have come from the incinerator.

“The high chimneys of the Okhla incinerator are a serious threat to migratory birds since they emit a range of toxic gases into their flight path,” said Roy.

On Aug. 14, the tribunal suspended further unauthorised construction in a 10-km wide eco-sensitive zone around the Okhla sanctuary, and ordered a fresh survey of the area by central and provincial authorities with a view to protecting it.

Faizi said the tribunal order has come not a moment too soon. “The Okhla waste-to-energy incinerator is absolutely unacceptable in this critical bird area and must be removed without further delay,” he said.

According to Roy, although the total number of visiting birds has declined, the range of bird species represented at the Okhla sanctuary appears to be increasing. “A total of 330 bird species has been recorded at the Okhla sanctuary, although some species are no longer being sighted.”

Feathered visitors to the Okhla sanctuary that figure on the ‘red-list’ of endangered bird species of the International Union for Conservation of Nature include the Ferruginous Duck, Black-tailed Godwit, River Lapwing, Egyptian Vulture, Oriental Darter, Painted Stork, Black-bellied Tern and Black-headed Ibis.

The tribunal is currently hearing multiple petitions asking for intervention against property developers, builders and a ‘sand mining mafia’ that defy existing rules that can help protect the Okhla sanctuary.

After it was discovered that illegal sand mining had caused the Jamuna to shift its course eastward, a crackdown involving seizures and arrests was carried out by Durga Shakthi Nagpal, administrator of Uttar Pradesh’s Gautam Budh Nagar district in which much of the Okhla sanctuary falls.

But on Jul. 28, three months after the crackdown was launched, Nagpal was controversially suspended by her political bosses in what was widely seen as a backlash from the construction industry that uses large quantities of river sand for its cement and concrete mixes.

Faizi said that only a people’s movement could save the sanctuary, which acts as a ‘green lung’ for congested and polluted Delhi that is home to 20 million people. “Recognising the Okhla sanctuary as a Ramsar site would be the best way to generate public interest in protecting one of the world’s truly unique wetlands.”

UNITED NATIONS, May 17 2013 (IPS)

Migratory birds, which play an important role in the complex web of life known as ecosystem services, are under threat as never before, with some species facing extinction within the next decade.

Ahead of the International Day for Biological Diversity on May 22, focused this year on water resources, experts are calling for greater international cooperation to find sustainable and cost-effective solutions to the problem of species loss and environmental degradation."Half of the world’s wetlands - natural water storage systems - have been lost over the past century." -- Nick Nuttall of UNEP

“Both water management boundaries and ecosystems rarely conveniently align with geopolitical boundaries,” notes the report Natural Solutions for Water Security, published by the Convention on Biological Diversity (CBD).

According to Francisco Rilla, information and capacity building officer at the Convention on Migratory Species (CMS), an intergovernmental treaty signed in 1979 in Bonn, Germany, “The ‘Big Five’ primary causes of biodiversity loss … are habitat destruction, overharvesting and poaching, pollution, climate change and introduction of invasive species.”

Migratory species are especially vulnerable “as they depend entirely on a network of well-functioning ecosystems to refuel, reproduce and survive in every ‘station’ they visit and upon unrestricted travel,” Rilla told IPS.

The U.N. Environment Programme (UNEP) notes that many migrating birds, such as cranes, storks, shorebirds and eagles, travel thousands of kilometres across flyways that span countries, continents and even the entire globe.

These birds use wetlands to rest, feed and breed along their migration routes.

However, “half of the world’s wetlands – natural water storage systems – have been lost over the past century,” Nick Nuttall, UNEP spokesperson, told IPS.

Because of the degradation of their habitats, some migratory bird species could lose up to nine percent of their populations, while others, like the spoon-billed sandpiper, could become extinct within a decade, leading to further ecosystem changes and ultimately impacting on human development.

Putting a price on biodiversity loss

In a statement ahead of World Migratory Bird Day on May 11-12, UNEP executive director Achim Steiner underlined that migratory birds “are part of the web of life that underpins nature’s multi-trillion-dollar ecosystem services,” which are the benefits and resources that nature offers to humankind. 

“[Migratory birds’] contribution to ecosystem services is increasingly starting to be measured in monetary terms,” Rilla told IPS.

In March 2007, at the request of the Group of Eight largest economies along with several developing countries, UNEP started an initiative called ‘The Economics of Ecosystems and Biodiversity’ (TEEB), aiming at studying the economic benefits of biodiversity and incorporating them into policy-making.

As an example of TEEB’s implementation, Nuttall explained how UNEP assisted Kenya in 2012 to calculate the economic value of the ecosystem services generated by the Mau forest northwest of the capital Nairobi.

The overall value was assessed at 1.5 billion dollars a year, a consideration that led to the restoration of the forest, as well as of other ecosystems supplying water to Kenyan cities.

The advantages of using natural infrastructure like forests and wetlands instead of human-built infrastructure, such as dams, pipelines, water treatment plants and drainage systems, are highlighted in CBD’s report.

For example, strengthened coastal ecosystems can function as buffer zones that protect coastal communities from storms; rehabilitating soil biodiversity and functions can enhance water availability to crops and hence improve food security; restoring forests can reduce erosion risks and help deliver better quality water.

This approach, known as “Ecosystem-based Adaptation” (EbA), which integrates biodiversity and ecosystem services in climate change adaptation strategies – though cheaper and more sustainable than building new artificial infrastructure – is still under-utilised, says the report.

Agricultural activities, which alone account for approximately 70 percent of global water use, could apply a similar approach.

“More sustainable forms of farming can … address water issues while enhancing biodiversity,” Nuttall told IPS. “A survey of thousands of small scale farmers in Africa by UNEP and the U.N. Conference on Trade and Development found that those who had switched to organic or near organic production had seen yields on average climb by 100 percent, in part because returning organic matter to the soils had increased water retention of the soil – like a sponge – and prolonged the growing season.”

Governance matters

“We live in an increasingly water-insecure world,” stresses the CBD report.

Although there is no global water scarcity as such, there is an imbalance in its regional distribution, with only 12 percent of the world’s population consuming 85 percent of the available water.

Sound governance and equity in the distribution of water-derived benefits seem therefore important questions in the debate.

Asked by IPS about sustainable water management strategies in South Asia, one of the most water-scarce regions of the world, Michael Kugelman, senior programme associate for South and Southeast Asia at the Woodrow Wilson International Center for Scholars, cited resource mismanagement as a root cause of problems.

He stressed the lack of interregional cooperation in the area, as well as of understanding of the connections between ecosystem protection and water resources.

“I think that at a government level that linkage is not made at all,” he said, “There are a lot of environmental NGOs that are bringing attention to these issues. … In some ways governments will take the lead from the NGO community.”

Water cooperation in South Asia is limited to some bilateral initiatives, such as the Indus Water Treaty between India and Pakistan.

At a global level, the main mechanisms dealing with biodiversity and water management are the Ramsar Convention on Wetlands (signed in 1971 in Ramsar, Iran) and the above-mentioned CBD, which was created at the 1992 Earth Summit in Rio de Janeiro, Brazil, and in 2010 adopted its Strategic Plan for Biodiversity for the period 2011-2020.

The United Nations declared 2013 the International Year of Water Cooperation.
