This tiny bird barely weighs more than a teaspoon of sugar, yet it connects Ghana with Europe. In the quiet wetlands of Salo in Ghana’s Keta Lagoon, a Eurasian Reed Warbler Acrocephalus scirpaceus was caught and banded by Timothée Schwartz, Scientific Director for A Rocha France. Seven months later, in September 2025, that same Eurasian Reed Warbler was recaptured in Sourbrodt, Belgium by ornithologist Emile Degros. This one-year-old warbler traveled nearly 5,000 km, connecting the wetlands of Ghana and the marshes of Europe in an awe-inspiring journey.
‘The recapture of this bird on European soil is a powerful symbol of the invisible threads that tie our ecosystems together.’ – Prosper Kwame Antwi, Programmes Manager, A Rocha Ghana
This Reed Warbler was captured during collaborative field surveys between A Rocha Ghana and A Rocha France as part of the ProBioDev project. Standing for ‘Promoting Biodiversity Conservation for Development’, the project represents an international effort to protect one of Ghana’s most important migratory bird stopover sites, the Keta Lagoon Ramsar Site.
Creatures of the Keta Lagoon Wetland
Keta Lagoon provides for local communities in abundant ways: it’s used for fishing for food and income, cutting reeds for thatch and weaving, harvesting salt, and irrigating crops. However, some of these activities have degraded the lagoon’s essential habitats. A Rocha Ghana is helping locals encounter the lagoon in a new way and engage with it sustainably.
Imagine looking out on the beaches where Leatherback Dermochelys coriacea, Green Chelonia mydas and Olive Ridley Lepidochelys olivacea Turtles come to breed. Amongst the mangrove trees, you may spot a swamp-dwelling antelope, the West African Sitatunga Tragelaphus spekii. The vulnerable West African Manatee Trichechus senegalensis swims around the mangrove’s underwater roots, alongside juvenile Flat Sardines Sardinella mardrensis, ancient-looking Needle Fish Strongylura senegalensis and a variety of shrimps.
And of course, there are the birds. Recognized internationally as a Ramsar Site, Keta Lagoon regularly welcomes over 100,000 birds at a time. It is a vital refuge for countless residents and migratory species journeying from Europe. This includes the Vulnerable Grey Plover Pluvialis squatarola, the Near-Threatened Eurasian Curlew Numenius arquata and a whole revelry of other, more common species.
Jewel-like Malachite Kingfishers Corythornis cristatus sport a blue and black crown. A chuckling ‘coo-coo coo ru’ indicates the presence of Laughing Doves Spilopelia senegalensis. Western Reef-Herons Egretta gularis stalk the shores alongside a variety of sandpipers, godwits and plovers.
Amidst this brilliant swirl of feathered creatures, our famed Eurasian Reed Warbler blends into the densely packed reedbeds, foraging for insects. Even if it’s hard to spot, the warbler’s jerky, melodic call and striking chirp give away its presence. Around March, it will begin its nocturnal migration back to Europe to breed.
‘This tiny traveller is more than just a scientific record,’ reflects Prosper, after the Eurasian Reed Warbler was recaptured in Belgium. ‘It’s a message of hope that by protecting wetlands and wildlife, we’re nurturing the bonds that unite our world.’
Local restoration with a global impact
The incredible routes taken by migratory birds act as invisible threads that stitch our world together. Sensitive to changes in climate, habitat and pollution, they bear the brunt of the harm humans have done to our environment. At the same time, restoring a site like Keta Lagoon has a global impact, supporting life far beyond Ghana’s borders.
Despite its importance for biodiversity, the Keta Lagoon wetland faces many threats. Between 10 and 30 percent of residents in the surrounding districts live in poverty, relying heavily on fishing, agriculture, and mangrove harvesting. However, there is a lack of community awareness of the importance of the site for nature and people. The wetland has been overexploited for its resources and polluted by agrochemicals, fertilizers and household waste.
Climate change is also a grave risk to the Keta Lagoon site and the surrounding communities due to sea level rise and storms of increasing frequency and intensity. Coastal vegetation, especially mangrove forests, is one of the most effective defenses against floods and storms, but they are being harvested unsustainably.
Compounding these environmental stressors is the lack of updated information on bird species and the habitats and sites most important for them, with limited bird monitoring taking place. A Rocha’s ProBioDev project was created to protect the lagoon for the many people and species that depend on it – in Ghana and beyond.
Through funding from the IUCN French Committee, A Rocha Ghana and A Rocha France are joining forces to combine scientific research, community empowerment and habitat restoration in the Keta Lagoon Ramsar Site. Over two years, the ProBioDev project aims to:
Conduct a comprehensive inventory of bird species and update habitat maps
Train local community members to monitor and protect bird populations
Promote eco-friendly livelihoods such as birdwatching tourism
Support mangrove restoration and ecological farming to enhance food security and climate resilience
In October 2025, A Rocha France conducted a second field mission in Ghana. Scientific Director Timothée Schwartz was accompanied by Charlotte Leon, A Rocha France’s nature manager at Les Courmettes environmental centre, and Andrew Newton, an ornithologist and long-time friend of A Rocha. After conducting an inventory of Keta Lagoon’s bird species several months prior (when they ringed the famed Eurasian Reed Warbler), the A Rocha France contingent returned to complete the inventories and train local teams in bird identification and monitoring.
A Rocha France led four bird ringing sessions, which brought together the many groups collaborating to protect the lagoon, including A Rocha Ghana, rangers from the Wildlife Division responsible for managing the Ramsar site, and rangers from the nearby Avu Lagoon site. Timothée led two training sessions on waterbird counting and identification, as well as data entry and analysis. With a new system for cataloguing data, local monitoring efforts will have an even greater impact on understanding and conserving this critical site.
On World Migratory Bird Day, the wider community was welcomed into the mission to conserve the lagoon. A Rocha hosted over 150 children, as well as the mayor and representatives of the local congressman, for a day of discovering and celebrating migratory birds. A friendly bird competition was followed by speeches and presentations on the concept of bird migration, the threats facing migratory birds and solutions for taking action. Finally, the group was brought out to the lagoon to observe the remarkable water birds living just steps from the school that hosted the event.
While a love for migratory birds is at the centre of the ProBioDev project, protecting them means conserving the habitats on which they depend and building systems where human communities thrive, as well. A Rocha Ghana is raising awareness among local communities of the importance of wetlands for biodiversity, livelihoods, food security and climate resilience. They are training locals, especially women and youth, in mangrove restoration and sustainable harvesting, while also training subsistence farmers in climate adaptation techniques that benefit biodiversity and ecosystems. By developing partnerships with local agencies, A Rocha Ghana is ensuring that the project has strong local buy-in and its benefits extend far into the future.
By protecting migratory birds, we are protecting the planet.
A Rocha’s Global Conservation Fund supports conservation work around the world, including reconciliation work in Uganda, a new marine programme in India, and sustainable livelihoods in Peru. A second round is now underway to pilot innovative approaches such as ‘tiny forests’ in the UK, evaluating long-term conservation scholarships in Kenya, and developing outdoor church initiatives in the Netherlands. In this recording, A Rocha International’s Nick Warren and Kuki Rokhum share the vision, successes, and challenges behind this growing global initiative.
A Personal View Of The Collaboration Between Finance And Nature.
This reflection explores whether finance and nature conservation are truly in conflict, or whether they can work together to address today’s environmental crises. Drawing on the history of environmentalism, modern economics and Christian theology, it considers how systems built around profit have often neglected nature – and how new models might better value both people and planet. It asks what it would take to build a truly regenerative economy grounded in stewardship, justice and the flourishing of all creation.
Key ideas
Modern environmentalism emerged partly in opposition to industrial capitalism, highlighting how profit-driven business practices and chemical-intensive industries were damaging both people and the natural world.
Over time, finance became increasingly focused on maximising shareholder profit above all else, often ignoring environmental and social costs. This led to economic systems that treated nature as an “externality” rather than something essential to human flourishing.
The article argues that environmental movements have sometimes framed business and finance as enemies of nature, but meaningful ecological change requires collaboration with investors, companies, and economic leaders
Although ideas like carbon credits and biodiversity markets attempt to account for environmental damage, truly regenerative economic systems remain underdeveloped, and many current financial approaches still fail to protect nature at scale.
From a Christian perspective, the article makes the argument that human flourishing and care for creation should not be seen as competing goals. Biblical ideas such as shalom, long-term stewardship, generosity, and “the community of creation” point toward economic models that value both people and the wider living world together.
"Are the two worlds of finance and nature conservation mutually exclusive or, in these crisis times, are there new possibilities for a fruitful collaboration?"
Are the two worlds of finance and nature conservation mutually exclusive or, in these crisis times, are there new possibilities for a fruitful collaboration? If so, some history on both sides needs to be acknowledged.
When the modern environmental movement began in the 1960s it followed a text-book tactic: name your enemy to gather your friends. Among others, Rachel Carson’s pioneering work and her influential book Silent Spring, first published in 1962, made it clear that the rapid growth of big business had effectively been poisoning the world. Pharmaceutical companies which had been involved in weapons production during the second world war period pivoted to manufacturing the key ingredients for the new weapons needed for the industrialisation of agriculture. DDT[i] was one of the first products to be identified as particularly harmful but over following decades the dangers to human health and the wider environment of increasing numbers of chemical compounds became more than obvious. The pollution that rapidly growing industries were visiting upon the world began to percolate into popular awareness, and that was before a realisation of their contribution to climate change had begun to be better understood.
Meanwhile, influenced by neo-classic economists such as Milton Friedman[ii], both industry and its investors were becoming increasingly focussed on financial return as the single metric of success. Friedman introduced his theory in a 1970 essay for The New York Times titled “A Friedman Doctrine: The Social Responsibility of Business is to Increase Its Profits”[iii] arguing that a company has no social responsibility to the public or society; its only responsibility is to its shareholders. He did introduce the caveat that serving the shareholder was to be done ‘within the bounds of law and ethical custom’ but one could argue that the damage was done. In a political context of de-regulation, other considerations of wider values that encompassed more comprehensive understandings of the social and environmental vocation of business were abandoned.
“Furthermore,one of the bigger failures of the market... was its inability to value nature or to price in the cost of environmental degradation."”
The emergence of more powerful communications media meant that public relations criteria pushed further towards brand protection rather than substance when it came to investing. The markets demanded a straightforward calculation of ‘money in and money out’ whether the medium for growth between the two was the planet or people. To satisfy those demands complex financial instruments were designed that simply used finance to create finance with ever more ephemeral products. Rapid globalisation of trade and events such as the subprime mortgage crisis of 2008 both created a context and demonstrated finance’s increasing detachment from the economy of the real world, accelerating a process that had its origins as far back as the beginning of the industrial age. Furthermore, one of the bigger failures of the market, even on its own terms, was its inability to value nature or to price in the cost of environmental degradation.
So it was not surprising that those who could not regard the physical world around them as merely an externality, or a necessary casualty for a closed financial system, became hostile to those who were responsible for creating the trading system itself. The narrative of the emerging environmental organisations and their conservation partners was “You may be wrecking the world, but we will save it.” In their influential and controversial 2004 essay “The Death of Environmentalism”[iv] Michael Shellenberger and Ted Nordhaus characterised that messaging as fatally flawed, asserting that it had restricted environmental concern to a largely wealthy constituency. They posited that the very change makers who needed to re-imagine economic activity as a force for care of ‘the earth and all that lives on it’ as Psalm 24:1 has it, were excluded from the conversation and treated as enemies. However, financial and industrial leaders were precisely those whose engagement was needed if any systemic change was to come about. Rather than those changes being the business of the green brigade who would then live off philanthropic scraps from the corporate table, or merely the result of consumer pressure dragging reluctant industrialists towards ‘sustainability’, a comprehensive effort was necessary that would involve every actor in shaping the world of human endeavour.
Recent times have seen a far greater understanding of the inevitable relationships within the human economy that must all flourish if nature is to survive.[v] The data of destruction and decline and its impacts is unarguable and is evidenced not least in the plight of the insurance industry. Even so, it is only to a far lesser extent – if the deployment of investment capital in both private and public sector is to be believed – that there is a growing understanding of all the natural relationships that must be maintained if human flourishing is to be achieved. In that regard, the money tells the story which is that we are very far from discovering how financial investment can prosper at scale without depleting or damaging nature[vi]. The emergence of carbon and more recently bio-diversity credits has seemed to some to at least have the advantage of recognising the costs to planet and people of our current way of financial and industrial life. But both the methodologies and the metrics remain contentious at best while to their critics they are merely an exercise in smoke and mirrors or ‘voodoo economics’. [vii] So it could be said that for now the possibilities and aspirations of a truly regenerative economic system remain unrealised.
“Recent times have seen a far greater understanding of the inevitable relationships within the human economy that must all flourish if nature is to survive."
So how might a Christian perspective be found amid these competing claims and voices?
Firstly, Scripture maintains that the flourishing of people and nature should be possible even in a fallen world. It should never be a zero-sum game where human communities and the web of life that sustains them are set against each other as irreconcilable enemies. The idea of Shalom or comprehensive peace, as envisioned by Old Testament prophets such Isaiah and Jeremiah, is one in which both are blessed. While we wait for the Kingdom of God it is incumbent upon us to work within its commitments and to expect to see signs of its coming even in such times of distress. The orientation of the Kingdom is not intended to be merely aspirational but practical.
Secondly, because the biblical analysis is that the world is broken, the work of reconciling the apparently competing needs and interests of people and the wider creation will never come naturally nor be easy to achieve. However, if those who are creating wealth continue take an adversarial approach towards nature and, as for the most part they are currently doing,[viii][ix]run blindly towards and beyond the real limits which are intrinsic to our finite planetary life, then current catastrophes will amplify towards increasingly disastrous outcomes[x].
Finally, and I am grateful to Nina de Souza Jensen for these insights, one of the major issues in reconciling financial and ecological perspectives is the issue of time. The former, with the exception of pension funds and sovereign wealth management, operates overwhelmingly on short-term perspectives and returns. However ecological time frames are necessarily long-term. So those who embark on investment over extended time frames such as forest restoration or tackling plastic pollution will need to be generous, and to acknowledge that they are not in control. Both are qualities that are inherent to the Christian view of the world and so can give inspiration to those who endeavour to deploy capital faithfully.
"The orientation of the Kingdom is not intended to be merely aspirational but practical."
While considering Christian approaches we have to admit that many efforts which seek to align biblical values with investment neglect to consider what the theologian Richard Bauckham has called ‘the community of creation’[xi] and are instinctively anthropocentric. Traditional interpretations of Scripture over recent centuries in the western world have been highly influenced by the individual and deeply personal perspectives of successive cultural movements from the Renaissance onwards. All that is relevant for people has been exclusively highlighted at the cost of the more biblical, creational framing which gives human existence its dignity and its meaning. There is no doubt that the global church has a way to go before it becomes second nature for us to consider creation when designing outcomes of blessing.
For these and many other reasons A Rocha has been exploring how investment might be applied to some of the really difficult situations we are seeking to address around the world and we invite anyone reading this to be in touch if they feel they wish to be involved. So far we have launched modest efforts in consultancy and aligned eco-tourism but long to scale up further. And we applaud organisations such as North Star Transition and one of their founders Jyoti Banerjee who is exploring creative and collaborative ways forward inspired by their Christian faith. He and North Star understand that in a created reality everything must inevitably be connected to everything else and so take an intentionally systemic approach. They practice hope that even the most entrenched opponents may come to realise that enduring solutions can only found with the engagement of everyone involved. Most of all they and everyone who is working in this kind of way now need examples at scale of true economic growth measured by criteria that include the wellbeing of every element in the God-given creation that we hold in trust.
