Restoration of protected lakes under climate change: what legal measures are needed to help biodiversity adapt to the changing climate? The case of Lake IJssel, Netherlands

Throughout the world, lakes are facing deterioration due to intensive economic use. Climate change is exacerbating this situation. The only way forward is through implementing massive ecosystem restoration and connectivity policies, adjusted water management, and policies aimed at assisted colonization of endangered species. Current international and EU law do not explicitly require such policies to be developed and implemented, at least not in a legally binding way. In order to discover the legal prerequisites that facilitate the adoption and implementation of climate change adaptation measures for lakes, it would be good to have a look at some of the current best practices. One interesting example of such best practices is Lake IJssel (IJsselmeer) in the Netherlands, a protected lake under the Ramsar Convention and the EU’s Natura 2000 framework. In this blogpost, I will have a closer look at the adaptation policies in place for this lake with the aim to discover the legal conditions that have to be met for the adaptation policy to be effective. This case study is part of a bigger paper on this topic that was presented at an international conference at the University of Tehran on 14 April 2019, available here.

The creation of Lake IJssel

Lake IJssel (IJsselmeer) only became an inland fresh water lake in 1932, when the former Southern Sea (Zuiderzee) was closed off from the North Sea through the construction of a dam, called the Closure Dam (Afsluitdijk).^[1] Originally, this was a sea arm, part of the estuary of the IJssel and Vecht rivers consisting mainly of marshes and shallow salt and brackish tidal waters. The sea arm was closed off from the North Sea in order to end regular floods that were occurring in the area and to create new agricultural lands to improve food security. After the construction of the dam, parts of the new lake area were reclaimed and converted into land. This land was not only used for agriculture, but also for new cities in order to reduce population pressures in the nearby Amsterdam urban area. The remaining water area became a series of interconnected inland lakes, all of which are now protected areas under both the Ramsar Convention and the EU Wild Birds and Habitats Directives.^[2] Lake IJssel also became the Netherlands’ most important fresh water reservoir for drinking water and agricultural irrigation. It is the biggest fresh water area in northwestern Europe.

Lake IJssel’s poor conservation status exacerbated by climate change

Many of the species and habitat types for which this lake has been designated under the EU Wild Birds and Habitats Directives are not in a favourable conservation status, as required by these important EU biodiversity instruments.^[3] There are several reasons for this. First, and foremost, the transition from this area from a coastal marshland area into an artificial fresh water lake had severe consequences for the naturally occurring ecosystems. A new natural equilibrium has not been reached yet. The water of the lake has excessive quantities of sediments and is increasingly low on nutrients and marshes are disappearing. Over-fishing and increasing pressure by recreation, combined with active human manipulation of water levels to allow for intensive farming and urbanization have turned the lake basically into a big tub with muddy, empty water. The number of fish and other water organisms have declined tremendously, as has the number of birds. Climate change is exacerbating this already poor situation through:^[4] increasing water temperatures (leading to reduced oxygen levels and increased harmful algae blooms), increasing intrusion of alien invasive species (such as the quagga mussel, which affects natural algae and native mussel populations, as well as power and water treatment infrastructure), increasing peaks both in low water levels caused by droughts and high water levels caused by increased precipitation and increased river water run-off, bigger impact of several chemicals, such as phosphates from agricultural run-off in case of high water situations, and chloride from upstream salt mines in France in case of low water levels in summer, bigger impacts from recreation due to longer recreation seasons, increased flood risks due to accelerated sea level rise, which will make it increasingly difficult to flow off river water into the (higher) North Sea.

Legal requirement to restore the degraded Lake IJssel

Lake IJssel was designated as a wetland of international importance under the Ramsar Convention in 2002 and as protected area under the EU Wild Birds and Habitats Directives’ Natura 2000 network in 2010. The EU Directives contain much stricter legal obligations than the Ramsar Convention and have much more legal force through the fact that EU legislation is directly binding under domestic law of the EU Member States and through an enforcement mechanism through the Court of Justice of the EU. As a consequence, the Ramsar Convention has lost much of its relevance for those areas that have also been designated under the EU’s Natura 2000 network (which is the case for all Ramsar sites in the Netherlands).^[5]

For areas designated under the EU Wild Birds and Habitats Directives, conservation goals need to be set, aimed at the specific habitat types and species for which these areas have been designated. As most of the habitat types and species for which the Lake IJssel has been designated under the Natura 2000 network are not in a favourable conservation status, many conservation goals aim at increased populations or at increased acreage for certain habitat types. The latter can only be achieved through restoration, hence restoration is a legal requirement for Lake IJssel. In order to comply with this requirement, the management plans for the lake have adopted a wide range of restoration actions, some of which focus on the climate change related measures discussed in this paper (ecosystem restoration and connectivity, adjusted management, assisted colonization). These will be discussed below. It should be noted that the management plans for Lake IJssel do not just focus on nature conservation, but on all relevant environmental issues. A range of legal frameworks apply to the lake, partly stemming from the EU, such as on water quality and flood management, partly from domestic level, such as on polluted water soils and spatial planning. Furthermore, all of these plans are part of a broader development policy for the Lake IJssel area, called ‘Agenda Lake IJssel area 2050’, covering not just nature conservation, but also water safety, (drinking) water supply, water quality, fisheries, sustainable energy, infrastructure and transport, sand  extraction, landscape conservation, culture, recreation and tourism.^[6]

Restoration plans for Lake IJssel

The first phase of the plans, which runs from 2017 until 2023, primarily aims at stopping the decline in quality and quantity of habitat types and species. To achieve that, the current plan has five main goals: improvement of marshes on the edges of the lake for breeding reed birds, creation of new sandy breeding areas for water birds that breed on sandy beaches, improvement of availability of food for birds, improvement and enlargement of certain habitat types, and more space and tranquility for birds.^[7]

Most, if not all of these goals align with the climate change related adaptation measures that are generally considered important, such as restoration and connectivity, and adjusted management. It is remarkable, though, that climate change is not mentioned a lot in the various documents detailing the restoration requirements for Lake IJssel. I assume that this is because of the already poor conservation status that requires urgent action even without climate change.

The following table lists some of the restoration measures that contribute to climate change adaptation for the lake (despite the fact that they were not specifically proposed with that focus).^[8]

Assisted colonization is not specifically addressed in the management plans. Yet, to some extend, this measure is relevant, although not connected to climate change. In the 1980s the Eurasian otter became extinct in the Netherlands, mostly due to water pollution in the previous decades. The species, however, was reintroduced and now is back in a viable population in the Lake IJssel area. Furthermore, some of the restoration measures do aim to facilitate the natural relocation of species that were not present in the area before. The latter is particularly true for the white tailed eagle that has colonized the area and has been breeding here since 2006. The artificial fish migration river mentioned above helps salmon and other migratory fish to recolonize the lake and the rivers feeding the river. The assisted relocation of soil disturbing fish species from another part of the area to the lake is considered with the aim to improve the quality of the water soil.

Enabling factors for the restoration plans for Lake IJssel

In this section, I will deal with some important enabling factors that determine the success of the plans sketched above: the available financial budget, the role of the various authorities and other stakeholders involved, and the the role of the general public.

Financial budget: The measures discussed above, go at a cost. It is, therefore, important to adopt a multi annual budget. Otherwise, the risk exists that the plans are not executed, or that implementation stops mid-way. In the restoration plans for the Lake IJssel, implementation costs for each of the measures proposed has been included. The estimated budget consists of two elements: costs for construction or establishment of the restoration measures (once off costs), and costs for the first ten years of maintenance of the restoration measures. The total amount of once off implementation costs is between 630 and 1,060 million euro plus between 41 and 89 million euro for maintenance costs for the first ten years.^[9]

The role of the various authorities and other stakeholders involved: The governance structure of Netherlands can be characterized as a decentralized unitary state. This means that central government involves the provinces, municipalities and water districts in the formulation and execution of its policies.^[10] Hence, consensus building is considered to be of vital importance and the Netherlands has a long tradition of always looking for consensus among all those involved. This tradition dates back to early coastal defense and land reclamation activities around 1200, so even predating the establishment of the Dutch State: such activities were only possible with the collaboration of everyone, and, thus through balancing everyone’s interests. This has led to the enactment of laws that have a subtle, and somewhat complex, system of joint decision-making on such topics as water management, nature conservation, and spatial planning. As a consequence, many government bodies are involved in the implementation of the restoration plans for Lake IJssel, as follows. Central government is responsible for coastal and flood defenses that are of national importance (i.e., all coastal defense systems and flood defense systems of the main rivers), as well as for complying with EU-law requirements (vis-à-vis the European Commission). Provincial governments are responsible for nature conservation, and for coordinating water management and spatial planning. Water district boards are responsible for water management (in a broad sense, including water related nature conservation), and municipal governments are responsible for local spatial planning. As the Lake IJssel area is located within four provinces, has 32 municipalities and six water districts, and since five central government ministries are involved in the broader development plans of the area, intensive collaboration among all of these actors is in order. Such collaboration is coordinated by the Minister of Infrastructure and Water. Also involved in this process are non-governmental stakeholders, such as (agri-) businesses and environmental NGOs. Environmental NGOs actually play an important role, as several NGOs own property within the protected areas.

The role of the general public: Local residents, businesses and NGOs are also involved through the regular administrative procedures that need to be followed with all government decision-making (at all levels) and that require effective public participation and access to justice. Hence, there are public hearings and other forms of public participation, and all interested parties have the right to go to court. Thanks to the intensive collaborative decision-making processes aimed at reaching consensus (as sketched above), there, generally, is broad support for the plans once they are adopted. Nevertheless, every administrative decision that is taken to implement the restoration plans, can end up in court. Often, court cases focus on the question whether a certain decision is in compliance with EU law, for example with the EU Wild Birds and Habitats Directives.

Assessment of the Lake IJssel restoration plans

The restoration measures included in the first management plan for Lake IJssel are important first steps to bring the ecological quality of the lake back to an acceptable level. Species and habitat types that are in a favourable conservation status are much more resilient to climate change than species and habitat types that are in a poor condition. The measures aimed at increased connectivity, such as the creation of a fish migration river and of new islands in the lake for the sake of nature are spectacular and have fascinating results even within the first few years after these measures were taken. It is also clear, however, that much more is needed to make the area completely resilient to climate change. Especially those measures aimed at restricting harmful human activities still need to be taken. So far, only some preliminary measures aimed at regulating commercial fishing and recreation were adopted. More restrictions, especially for commercial fishing are considered necessary, which requires redistribution of existing fish permits and closing of certain parts of the lake for fishing. More drastic limitations on shipping and agriculture will follow from restoring natural water levels. Creating more connections with the sea, between the various parts of the lake area, and with the rivers feeding the lake, would also greatly enhance the resilience of the area, but is considered to be risky from a water safety perspective. The current approach of setting small steps towards a gradual more natural ecosystem seems effective for now, but we have to wait and see whether this approach will still work when tough decisions need to be taken that are costly and will have clear negative economic side effects.

Ecological Literacy and Restoration

(Professor of Environmental Law, University of Tasmania; Tilburg University’s Global Law Visiting Chair 2017)

In early 2015 my wife and I purchased 66 acres of wild landscape in our homeland, Tasmania, and set about ensuring its indefinite protection by putting a conservation covenant on the property title.  With this legal protection to “Blue Mountain View”, as we call our land, we joined other like-minded neighbours committed to safeguarding this beautiful niche in Tasmania’s Huon Valley. We have also since participated in some wildlife monitoring projects with environmental groups to better understand the local biodiversity and thereby facilitate long-term conservation planning.

Becoming an environmental steward with legal responsibility to protect and improve the ecological values of a small piece of our planet is a great privilege, providing exceptional opportunities to forge a more intimate relationship with, and knowledge of, the natural world. This experience reminds me of the writings of Harvard biologist Edward O. Wilson who hypothesized that human beings possess biophilic tendencies.^[1] Yet biophilia, like other affections, is unlikely to flourish if not nurtured. If our experience of nature is limited to desolate landscapes with few wildlife beyond the ubiquitous rats, pigeons and common weeds, we are unlikely to appreciate nature’s richness and beauty. Equally, if our daily lives are spent amidst car parks and shopping malls, we will hardly understand the complexity of ecosystems and the need to care for them. In our highly urbanized, consumer lifestyles, the impoverished opportunities for direct interactions with wild places are one of the principal obstacles to making environmental conservation a social priority.

My association with Blue Mountain View has enabled me to acquire much greater ecological literacy than I ever gained from just reading literature and watching nature films. I have come to learn much about the habits of rare or engendered species that inhabit it, such as Tasmanian Devils and Eastern Quolls, and develop a greater sensitivity to nature’s temporalities as observed from the fruiting and flowering of vegetation or the seasonal migration of birds.

But how can we engage the general public with the natural world so as to similarly build ecological literary, respect and affinity?  This is a multidimensional task of which environmental law can only play a part.^[2]

A key strategy must be community participation in ecological restoration, the practice of repairing historic or recent damage to landscapes and seascapes. The practice is evoked by the work of New York artist Alan Sonfist. He erected numerous monuments in cities around the globe to commemorate and “heal” their lost ecology. His archetypical work is “Time Landscape”, constructed over 1965 to 1978 in Manhattan in cooperation with the City Botanical Gardens. His “landscape” recreated the original indigenous vegetation of New York on an empty street corner in Manhattan, and the living artwork evokes the processes of nature reclaiming itself.  Serious ecological restoration, of course, must be tackled on a much grander scale.

Restoring nature is vital to defend against the upheavals of the Anthropocene. We shouldn’t assume that sustainability – the dominant goal of modern environmental law – is achievable using current environmental conditions as baselines for legal protections because those conditions are often too degraded to meaningfully sustain. Instead, attaining sustainability may also require some recapturing of prior ecological conditions – lands may need to be replanted with vegetation, fish stocks replenished, and landscapes cleansed of contaminants.

The law must prioritise ecological restoration, a task that will require a major shift from current legal precedents. Major environmental legislation in most countries offers few provisions devoted to this task, mostly focusing on remediation of contaminated brownfields or former mines rather than restoration of entire ecosystems.^[3] Fortunately, the governance deficits are starting to be filled by some fascinating initiatives from non-state actors, namely environmental NGOs, community groups, farmers and Indigenous peoples, collaborating voluntarily to restore and rewild nature.^[4]

The examples include Gondwana Link, restoring a 1000 km stretch of Western Australia that suffered catastrophic land degradation from misguided farming. Began in 2002, the project aims to reconnect fragmented natural habitats to create a holistic ecological system, through outright purchase of high priority lands and conservation covenants on other properties that are then subject to various restorative interventions.^[5] In North America, the Y2Y project – denoting Yellowstone to Yukon – is using a similar approach to Gondwana Link, except over a bigger scale along the Rocky Mountains and involving more jurisdictions and actors.  In New Zealand, which has suffered among the world’s worst biodiversity loses – don’t believe the deceptive “100% Pure” slogan that the country advertises – restoration has been led by community groups sometimes in partnership with government land managers. They are creating huge fenced sanctuaries in which exotic vermin are removed to allow the remnant avifauna to regenerate.^[6] And in Scotland a charity called Trees for Life is restoring 230,000 hectares of the ancient Caledonian forest that was grazed and logged to near destruction several centuries ago.^[7]

Another approach, better suited to urban denizens, is called “reconciliation ecology”. The term was apparently coined by Michael Rosenzweig to describe restoration projects that benefit people by drawing them closer to their natural environs, including providing aesthetic and recreational benefits.^[8] Such reconciliation often takes place in urban areas to bring nature closely into people’s daily lives, such as expanded city parks, restored waterways, and green roofs. One outstanding example is “Zealandia”, a restored bird-rich sanctuary, located near the heart of Wellington, the capital city of New Zealand. Through reconciliation activities, people become more aware of their degraded environs, the opportunities to improve them, and thereby hopefully acquire greater ecological literacy.

‘Citizen science’ is another movement that touches on similar ideas but uses different methods. Citizen science projects involve lay people participating in environmental monitoring to help researchers understand environmental baselines and changes that can then feed into management actions including restoration. Citizen science taps into a valuable community resource while enhancing participants’ ecological knowledge and commitment. Citizen science projects include tracking marine plastic debris^[9] and counting birds.^[10] Advances in information technology, both in recording and sharing the data such as GPS and remote camera ‘trapping’, have greatly expanded opportunities for citizen science to recruit larger audiences of volunteers. I have been involved in one such project on Blue Mountain View recently.

But such community-based initiatives aren’t enough. Volunteerism may not be sustainable in the absence of reliable funding, may lack influence when confronted with uncooperative landowners, and may be undermined by antagonistic government policies and regulations that enable inappropriate economic developments. For instance, some Australian states have enacted recent legislative changes that make it easier for landowners to clear native vegetation.^[11] Environmental lawyers must advocate ways for governments to play a more positive role, while preserving community initiative. Such roles could include more generous seed funding and tax breaks, coupled with reforms to land use planning and inclusion of stewardship obligations in all property tenures. Legislative mandates for sustainability should also be redefined to include obligations for restoration and reconciliation where existing ecological baselines are too degraded.

Of course, social change will require more than just law. The arts can also play a special role in enlivening people’s imagination and building their commitment to restoring nature. German artist-entrepreneur Dirk Fleischmann’s project “My Forest Farm” is one of the most ambitious artworks that illustrate this stance. The zero-carbon footprint art “work” is a voluntary carbon–offset program in the form of a reforestation initiative in the Philippines. In 2008, Flesichmann began planting nearly 2,000 trees on four acres with the aid of the local community. His project aims to challenge the booming carbon offset-market which he believes wrongly simplifies the issues of climate change by pretending that the problem of greenhouse emissions can be solved simply by purchasing offsets (an efficient transactional mechanism suited to busy people with no time to contemplate the environmental issues at stake).  My Forest Form reveals the complexities and time-consuming process of carbon-dioxide sequestration. Although his project results in carbon off-setting, he does not offer the carbon credits for sale. Instead, Fleischmann offers art – each of the trees is photographed and its GPS location recorded, and then exhibited in galleries and sold via the project website for 10 euros each. The earnings help fund the reafforestation project and educate the public about nature’s time-scales.

In conclusion, when reflecting on the roles of environmental restoration and reconciliation, we should appreciate that it is not just about improving nature but also improving human society. Restoring damaged ecosystems is not a viable long-term proposition if humankind remains emotionally and cognitively detached from its natural environs. Without inculcating greater ecological literacy, society will likely just repeat its past mistakes and undo any gains from new restorations. Participation in restoration projects can help communities understand their place in the deep time-scales of Earth’s landscapes, and may help nurture their biophilic impulse. Not everyone can elope to a place like Blue Mountain View, but we should all have some opportunities to engage with and learn about nature in which we are embedded and dependent like a cell within a body.
