Climate change and health experts are warning of the growing threat to public health in Europe from global warming as rising temperatures help potentially lethal diseases spread easily across the continent.

This summer Europe has had to contend with record temperatures, drought, and destructive storms caused by heat and wildfires as forests in turn are left parched.

It has also, though, seen a spike in cases of the West Nile Virus – which by early September had claimed 71 lives – and the dramatic spread of the potentially lethal vibrio bacteria in an exceptionally warm Baltic Sea. The West Nile Virus is a viral infection spread by mosquitos and can cause neurological disease and death. Various species of vibrio bacteria cause Vibriosis, which can sometimes lead to deadly skin infections or gastrointestinal disease.“We need to think about preventing health problems by dealing with the causes of climate change itself.” — Anne Stauffer, Health and Environment Alliance (HEAL).

And there have been warnings that global warming has increased the risk of tick-borne diseases on the continent and that the geographical range of mosquitoes, which can transmit diseases like dengue, chikungunya, and Zika, is also expanding.

While disease experts are keen to stress that climate change is just one factor involved in the greater incidence of tropical diseases in Europe – increasing global travel, unplanned urbanisation and others factors are also involved – they do, however, agree that changes to temperature, rainfall and humidity make it easier for mosquitoes and other vectors to spread, survive and pass on infections.

Meanwhile, the incidences of vibrio infections – which can cause lethal illnesses in some people with compromised immune systems – reported in the Baltic Sea this year do appear to be directly linked to higher temperatures.

Jan Semenza, acting head of Section Scientific Assessment at the European Centre for Disease Prevention and Control (ECDC), told IPS: “The warming of the Baltic Sea is clearly related to global climate change and the increase in sea surface temperatures there is linked to [the increase in] vibrio bacteria.

“There seems to be a link with a warming climate and vibrio infections in the Baltic Sea.”

He added: “Climate change projections for sea surface temperature ….. indicate a marked upward trend during the summer months and an increase in the relative risk of  these infections in the coming decades.”

Groups dealing with the impact of climate change on health say that this year has been a watershed in European perception of climate change and its effects.

Anne Stauffer, director of Strategy at the non-profit Health and Environment Alliance (HEAL) group which addresses the effects of climate change on human health, told IPS: “In terms of public awareness this summer’s heatwave has really made people see that climate change is happening in Europe and that we are facing threats.

“In previous years people thought about the effects of climate change only in terms of what’s happened in Africa and other places, not Europe, but now they see that Europe is affected and that Europe is facing challenges.”

But while public awareness of the health threats of climate change in Europe has improved over the last decade, it is still lacking, she says.

Experts on tropical diseases agree that in some countries, people are, perhaps understandably, ignorant of even the presence of certain diseases in Europe.

Rachel Lowe, an assistant professor at the London School of Hygiene and Tropical Medicine, told IPS: “It would probably not occur to a lot of people in, say the [United Kingdom], to think about West Nile Virus when they go to Romania.”

Indeed, some tropical diseases have been present in Europe for many years, but confined to very southerly latitudes, while ticks, some of which can carry lyme disease (results in flu-like symptoms and a rash) and encephalitis (inflammation of the brain through an infection), are present in many parts of the continent.

But this year has seen a rise in cases of tick-borne encephalitis in central and southern Europe.

But with temperatures rising, that could change in the future. Cases of West Nile Virus, which have been reported in some parts of Europe for many years now, were much higher this year than in recent years and were seen much earlier than previously. This has been put down, in large part, to higher temperatures earlier in the year.

At the same time, there has been a documented expansion in the range of disease-carrying ticks in recent years to more northerly latitudes and higher elevations. Hot summers and mild winters have also been reported to be linked, along with other factors, to high incidence of tick-borne disease in certain parts of central and northern Europe.

A spokesman for the World Health Organization (WHO) told IPS: “Increases in temperatures in Europe might allow the establishment of tropical and semitropical vector species, permitting transmission of diseases in areas where low temperatures have hitherto prevented their over-wintering.”

Facing this potential threat, the WHO’s European Region Office has devoted increasing attention over recent years to what it says is the “emerging challenge of vector-borne diseases”.

It has developed a regional framework for surveillance and control of mosquitoes and recommends involving a mix of action, including, among others, political commitment supported with adequate financial resources as well as community engagement for both personal protection against insect bites and vector control activities.

But experts say that general awareness of the presence and threat of tropical diseases in Europe needs to be raised, especially as climate change models see similar long, hot summers as well as milder winters becoming more common across the continent in future and countries could suddenly face outbreaks of diseases they have not had to deal with in the past.

The WHO spokesperson told IPS: “Due to globalisation, increasing volume and pace of travel and trade and weather patterns, vector-borne disease may spread to new areas, thus affecting new populations never exposed to them before.

“In these areas, low general awareness about diseases such as West Nile Virus, dengue or chikungunya among the public and both human and animal health professionals might challenge early detection of cases.”

And Lowe told IPS: “People need to be more aware of this [tropical diseases in Europe]. People are becoming more aware of infectious diseases in general, but probably not so aware of the fact there are certain infectious diseases in Europe.”

It is not just public awareness, though, which will help Europe deal with the health threats posed by a changing climate. Whether, for example, mosquito-borne disease outbreaks, would be successfully contained, would depend on a number of factors. “This would include factors such as surveillance of mosquito spread, mosquito control as well as general public awareness,” Lowe told IPS.

The WHO told IPS that public health advice needs to be communicated to people for self-protection and while authorities need to make sure mosquito breeding sites are drained so that they do not become breeding grounds for mosquitos while doctors need to be regularly trained to recognise diseases which were uncommon in Europe.

But what some other experts suggest is, rather than trying to deal with outbreaks of diseases, governments should be working to halt climate change and prevent disease outbreaks happening in the first place.

Stauffer told IPS: “There are still unknowns with regards to the health threats potentially posed by climate change and we do not know how they will play out… but the lesson learnt from this summer is that we need to strengthen efforts to tackle climate change – not just adapting healthcare to cope with a warmer climate but also acting to reduce emissions.

“We need to think about preventing health problems by dealing with the causes of climate change itself.”

South-South Cooperation in a Transformative Era

On 12 September, the international community commemorated the UN Day for South-South Cooperation. This is an important acknowledgement of the contributions of Southern partnerships in addressing the many development challenges that confront the international community, such as poverty, climate change, inequality, contagious diseases and humanitarian crises.

South-South cooperation is a unique arrangement where two or more developing countries share technical skills, exchange knowledge, transfer technologies, and provide financial assistance. These collaborations are built on the principles of solidarity, respect for national sovereignty, non-conditionality, national ownership, and mutual respect.

This year’s commemoration was particularly significant, as it marked the fortieth anniversary of an important milestone in international cooperation – the adoption of the Buenos Aires Plan of Action for Technical Cooperation Amongst Developing Countries (BAPA). BAPA institutionalized cooperation amongst developing countries, creating a strategic framework for furthering cooperation in technical and economic areas.

But cooperation amongst developing countries did not begin forty years ago – it traces its origins to the anti-colonial solidarity movement of the twentieth century. The practice gained further popularity in the 1950’s and 1970’s as newly independent States with limited capacities looked for independent ways to accelerate their development, away from the Cold War dichotomy of the day.

Forty years after the adoption of BAPA, the international system is undergoing a major systemic transformation, with new pillars of growth and influence emerging from the global South. Through collective voice and action, developing countries are actively contributing to the building of a more prosperous and peaceful world.

Developing countries today account for the largest share of global economic output and are playing an active, constructive role in traditional institutions of global governance as well as creating new institutions that are Southern-led.

In a noteworthy trend, development solutions increasingly originate from developing countries themselves. Harnessing the abundance of innovative solutions, brought about by its economic growth and advances in technical competencies, the global South now charts its own unique development path.

Developing countries are now drivers of innovation in ICT, renewable technologies, infrastructure development and social welfare. Pooled medical procurement is lowering costs and increasing access to life saving medicines. Southern-led mediation mechanisms for conflict prevention continue to prove especially effective in reducing violent conflicts.

Technical cooperation in agriculture is greatly improving the yields in agricultural output. Transfer of technologies and vast interregional infrastructure investments are facilitating access to international markets for medium and small-scale enterprises.

Southern-based centres of excellence and knowledge hubs have become key vehicles for promoting mutual learning, leading to reduction of poverty and the growth of an emerging middle class.

With this newly formed confidence, the global South progressively looks within itself for ideas, knowledge and skills for tackling many of its common challenges. This enhances its national and collective self-reliance, a major objective of BAPA.

As the capacities of developing countries have improved, there has been a corresponding expansion of the scope of South-South cooperation beyond technical cooperation to other areas. South-South cooperation today includes, amongst other instruments, technological transfers, knowledge exchanges, financial assistance, technical assistance as well as concessional loans.

As a consequence, interregional forums and summits for dialogue amongst developing countries have become an important platform for enhancing South-South policy coordination, launching joint initiatives, and committing resources for infrastructure development, trade and investments – vital for ensuring sustainable development.

Triangular cooperation – Southern-driven partnerships between two or more developing countries, supported by developed countries or multilateral organizations – is increasingly playing a role to ensure equity in partnership and scaling up of success.

In light of this, the United Nations General Assembly has decided to commemorate the fortieth anniversary of the adoption of BAPA by convening a High-level conference (BAPA+40) to be held from 19-21 March 2019 in Buenos Aires, Argentina. BAPA+40 provides a great opportunity for the international community to further strengthen and invigorate cooperation amongst developing countries.

Although great strides have been made by developing countries in improving the living conditions of millions of its people, complex development challenges still persist. Global economic transformations and its corresponding consequences on production patterns present a particular challenge to developing countries.

Automation poses a great risk to job creation in the South; climate change has particularly adverse effects on Small Island Developing States and Least Developed Countries; traditional partnership models are re-evaluated and inequality continues to rise. The global South will play an important role in overcoming these challenges.

The United Nations system continues to support the collaborative initiatives of developing countries by advocating, catalysing, brokering and facilitating such collaborations across many spheres.

Drawing on its vast presence across the global South, the United Nations is well placed to identify development capacities and gaps existing in developing countries while collecting, analysing and disseminating best practices and lessons learned towards the implementation of the 2030 Agenda for Sustainable Development and other internationally agreed development goals.

As the international community enters the third year of the implementation of the 2030 Agenda, concrete development solutions and resources from the global South are critical to achieving the Sustainable Development Goals. Effective development solutions that have worked in a few countries of the global South can be scaled up through South-South cooperation and triangular cooperation to accelerate sustainable development, particularly in countries that are lagging behind.

More and better South-South cooperation is essential to building a better world that leaves no one behind.
