Restoring Estuarine and Coastal Habitats in the North East Atlantic
Speech by Emma Howard Boyd, Chair of the Environment Agency Natural History Museum.
At the Environment Agency’s recent flood and coast conference, I shared a platform with the writer and broadcaster Nicholas Crane, who you probably know from the television programme: “Coast”.
Britain has only been occupied for 12,000 years… It’s all happened so quickly - we’ve gone from nobody being here at all in 9,500BC to 64 million of us being here today.
Personally speaking, 12,000 years seems like quite a long time.
Maybe that’s because I’ve never studied geology.
But, when experts put our present challenges in such a grand historical context I think it’s worth listening.
Speaking at the World Economic Forum in January, David Attenborough said:
The Holocene has ended. The Garden of Eden is no more. We have changed the world so much that scientists say we are in a new geological age: the Anthropocene, the age of humans.
Last year, the Intergovernmental Panel on Climate Change said we have 12 years to hold global warming to 1.5°C above pre-industrial levels… and even if we do, the impacts of climate change - like floods, heatwaves, storms, drought, and sea-level rise – will increase.
As the Extinction Rebellion activists remind us again this week, we need to act, but last week, the Committee on Climate Change made clear:
- We are not reducing emissions fast enough.
- Businesses, infrastructure, technology, and people are not prepared for weather impacts that will get worse in the next 11 years.
The estuarine and coastal environment of the UK…(Where over a third of people live)…has changed substantially from its natural state.
Even without human intervention, the coastline has never stayed in the same place, but climate change is increasing and accelerating these processes.
England has also lost about 85 per cent of its historic saltmarsh.
We have gone from over two hundred thousand hectares to around thirty four thousand.
Some areas which have experienced 100 per cent loss of saltmarsh have not recovered in any way.
It is estimated that more than 90 per cent of our native oyster biogenic reefs have been lost.
More than 50 per cent of our water bodies no longer have seagrass where it once grew.
But, I don’t think we should despair.
Human beings are agile and can adapt.
The blue whale hanging from the ceiling, here in the Natural History Museum, reminds us of that.
In the 1800s there were 350,000 to 400,000 blue whales across the world’s oceans.
After decades of commercial hunting only around 7,000 to 10,000 were thought to be left in 1966.
That year, in London, the decision was taken to legally protect blue whales.
Since then the population is believed to have grown to between 10,000 and 13,000 with some saying it could be as high as 20,000.
This conference is about changing the story like that for the UK’s coastal habitats.
Our near-shore seas and estuaries in the North East Atlantic have been transformed by human activity with significant losses of key habitats and the services they once provided.
We can reverse some of these changes and restore habitats.
The 25 Year Environment Plan sets an ambition to deliver environmental net gain and to restore marine biodiversity.
This creates the space for everyone in this room to raise their ambition higher… together.
So how should we act?
In the government’s National Adaptation Programme, the Defra Minister Lord Gardiner, wrote:
While we continue to play a leading role in international efforts to keep global temperature rises well below 2°C… our resilience will only be robust if we prepare for worse climate change scenarios.
The Environment Agency, is a regulator, advisor and operator out to three nautical miles.
We need to protect people and businesses on the coast through flood protection schemes.
Earlier this year, we released a draft Flood and Coastal Erosion Risk Management Strategy to 2100.
We said: We can’t win a war against water by building away climate change with infinitely high flood defences.
We need to be more resilient.
We need to help communities better understand their risk and give them more control about how to adapt and respond.
And, we need to look at more nature based solutions.
Last week, Minister Coffey announced a Call for Evidence on flooding and coastal erosion policy.
We will be working closely with government and partners to finalise our Strategy later this year.
As the Committee on Climate Change reported last week, society urgently needs to invest in Nature based Solutions such as afforestation, peatlands, and saltmarsh to draw down carbon and ensure that we can adapt to the impacts of a changing world.
Today, we want to establish a network for restoration of estuarine and coastal habitats and species.
This has – remarkably - never been done before…
Certainly not across government bodies, industry, NGOs and academia.
We want you to share your knowledge and experience.
We hope to take stock of what we have lost, what projects are underway, and look to the future to see what more we can do collectively.
Afterwards we hope to develop a much larger programme of restoration.
My colleague Pete Fox will be elaborating on the opportunities for partnership in a moment.
No one organisation can do this alone.
Green Finance has a significant role to play.
In the recent Green Finance strategy, the government increased the expectation for financial institutions - and regulators - to consider the impacts of climate change within their investments.
The strategy says the government will work with international partners to catalyse market-led action to enhance nature-related financial disclosures.
This will complement the global review of the economics of biodiversity by Professor Sir Partha Dasgupta.
And, it will mirror the success of the Task Force on Climate-related Financial Disclosures’ approach by supporting the private sector to develop consistent disclosures to better manage nature-related financial risks.
This is important, but we also need a large scale redistribution of capital towards the types of green assets that I hope you will discuss today.
But, we’re not just talking about “green” initiatives – this work is in everybody’s financial best interests.
The marine environment has a tremendous ability to recover.
Climate change threatens to overshadow protective management measures and lead to considerable loss of ecosystem services.
We need practical interventions to restore habitats, and increase ecosystem service resilience.
I hope that today’s conference helps to move the discussion about coastal habitats on from protection - to restoration.
We want to achieve greater resilience for people and wildlife at the coast: restoring, enhancing, and protecting the benefits we receive.
All of us benefit from the coast – particularly in a country where it is never more than 84 miles away.
Thank you very much.
