Climate change: Scientists warn over impact on food security and oceans

Published

on

UN climate scientists presented MEPs with new evidence on how climate change is affecting food production and oceans.

The Intergovernmental Panel on Climate Change is the United Nations body for assessing the science related to climate change. In August, it presented a report on climate change and land and in September one on the oceans and cryosphere in a changing climate. The reports are the latest scientific input for the UN climate summit COP25 to be held in Madrid in December.

The scientists behind the reports presented their findings to Parliament’s environment, development and fisheries committees on Wednesday 6 November.

Food production and climate change a two-way street

Professor Jim Skea told MEPs climate change was exacerbating land degradation, such as erosion and pollution, which in turn affects infrastructure and people’s livelihoods. Better land management can help tackle climate change but it must be complemented by other action, he added.

Dr Jean-François Soussana noted that the food system accounts for between a fifth and a third of all greenhouse gas emissions caused by humans. At the same time, climate change affects food security through declining crops of wheat and maize. He warned that in future the stability of our food supply would decrease further as the magnitude and frequency of extreme weather events increases.

Melting ice, rising seas

According to scientists, the rise in sea level is accelerating, mainly due to the Greenland and Antarctic ice sheets melting faster.

Professor Hans-Otto Pörtner warned that in a business as usual scenario the sea level is estimated to rise about five metres by 2300. In addition, in warming oceans marine life has access to less oxygen and nutrients, putting food security at risk for communities dependent on seafood.

Pörtner added: “To minimise the severity of the impact of climate change, every bit of warming matters, each year matters, each choice matters, and most importantly, political and societal will matters.”

Western Indian Ocean region has declared 550,000 square kilometers as protected

Published

on

The Western Indian Ocean region has declared 143* marine and coastal areas as protected – an area covering 553,163 square kilometers, representing 7 percent of the total Exclusive Economic Zone (EEZ) for the region – according to a new publication by the UN Environment Programme (UNEP)-Nairobi Convention and the Western Indian Ocean Marine Science Association.

The Marine Protected Areas Outlook, released today, indicates that almost half of the total area – an estimated 63 percent of the overall square kilometers – was brought under protection in the seven years since the 2015 adoption of Sustainable Development Goal 14.5, which committed countries to conserving at least 10 percent of their marine and coastal areas by 2020.

This Outlook examines the current and future status of Marine Protected Areas (MPAs) in Comoros, Kenya, France (in its Western Indian Ocean territories), Madagascar, Mauritius, Mozambique, Seychelles, South Africa, and Tanzania, emphasizing the increased commitment of countries to strengthen marine protection. In 2019 alone, Seychelles brought 30 percent of its Exclusive Economic Zone under protection, safeguarding the habitats of 2,600 species, while South Africa declared 20 new MPAs – enabling both countries to exceed the 10 percent target. Comoros has developed new MPA-specific legislation, while over three hundred Locally Managed Marine Areas – i.e., areas in which coastal communities shoulder the mantle of conservation – have been declared across the region.

The publication further documents the dozens of proposed MPAs currently under consideration by countries, which would cover an additional 50,000 square kilometers or more. Nevertheless, with only 7 percent of the region’s total EEZ under protection, greater momentum and investments will be required by countries to reach the more ambitious target of 30 percent protection by 2030, as proposed under the Global Biodiversity Framework.  

Although the ocean provides us with resources essential for survival, including food, employment, and even oxygen, the world is damaging and depleting it faster than ever. Soon, the region may no longer be able to count on the many jobs, health, and economic benefits – valued at 20.8 billion USD – that the Western Indian Ocean provides. Marine protected areas offer one of the best options to reverse these trends. 

“A well-managed MPA can bring significant economic, social, and environmental benefits to a country,” said Yamkela Mngxe, Acting Director of Integrated Projects and International Coordination in South Africa’s Department of Forestry, Fisheries and the Environment. “They can increase food security by preventing the overexploitation of fish stocks; create and protect jobs in the tourism and fisheries sectors; build resilience to climate change; and protect species and habitats.”

Though countries in the region have made significant strides in protecting its marine and coastal areas, the Outlook outlines best practices, challenges, and several opportunities to build on thisprogressto ensure the entire region meets future Global Biodiversity Framework targets on marine protected areas. The Outlook’s assessment of the management effectiveness of MPAs indicates that MPA frameworks and institutions do not always function effectively. Nor is relevant legislation consistently implemented, due to financial or personnel capacity gaps; weak enforcement on MPA boundaries; and management decisions that are not guided by science.

Key recommendations from the Outlook therefore include:

  1. The need for dedicated budgets for MPA management;
  2. Adopting proactive law enforcement and compliance strategies to ensure MPA regulations and guidelines are being respected which could be informed by the best practices in fishery reserves like Mauritius, which have helped to restore fish stocks and protect biodiversity;
  3. Incorporating research and monitoring programmes on biodiversity and ecosystems into decision-making in MPAs;
  4. Strengthening community engagement in marine protection by implementing lessons learned by the MIHARI Network, which brings together more than 200 Locally Managed Marine Areas in Madagascar.

“The MPA Outlook comes at a time when the region has embarked on large-scale socio-economic developments that are equally exerting pressure on MPAs,” said Hon. Flavien Joubert,Minister of Agriculture, Climate Change, and Environment of the Seychelles. “The Outlook thus provides some answers and innovative approaches to minimize the scale of negative impacts on MPAs.”

The MPA Outlook concludes that by seizing the opportunities it presents, countries in the region can capitalize on this progress to safeguard the Western Indian Ocean’s immense natural beauty and resources for generations to come – and sustain momentum towards achievement of the post 2020 biodiversity framework targets.

Deadly flooding, heatwaves in Europe, highlight urgency of climate action

Heavy rainfall that has triggered deadly and catastrophic flooding in several western European countries, is just the latest indicator that all nations need to do more to hold back climate change-induced disasters, the World Meteorological Organization (WMO) said on Friday.

The agency said that countries including Belgium, Germany, Luxembourg and the Netherlands had received up to two months’ rain in two days from 14 to 15 July, on ground that was “already near saturation”.

Photos taken at the scene of some of the worst water surges and landslides show huge, gaping holes where earth and buildings had stood until mid-week, after media reports pointed to well over 100 confirmed fatalities in Germany and Belgium on Friday morning, with an unknown number still missing across vast areas.

“We’ve seen images of houses being…swept away, it’s really, really devastating”, said WMO spokesperson Clare Nullis adding that that the disaster had overwhelmed some of the prevention measures put in place by the affected developed countries.

In a statement issued by his Spokesperson, the UN Secretary-General António Guterres, said he was saddened by the loss of life and destruction of property. “He extends his condolences and solidarity to the families of the victims and to the Governments and people of the affected countries.”

The UN chief said the UN stood ready to contribute to ongoing rescue and assistance efforts, if necessary.

“Europe on the whole is prepared, but you know, when you get extreme events, such as what we’ve seen – two months’ worth of rainfall in two days – it’s very, very difficult to cope,” added Ms. Nullis, before describing scenes of “utter devastation” in Germany’s southwestern Rhineland-Palatinate state, which is bordered by France, Belgium and Luxembourg.

Highlighting typical preparedness measures, the WMO official noted In Switzerland’s national meteorological service, MeteoSwiss, had a smartphone application which regularly issued alerts about critical high-water levels.

The highest flood warning is in place at popular tourist and camping locations including lakes Biel, Thun and the Vierwaldstattersee, with alerts also in place for Lake Brienz, the Rhine near Basel, and Lake Zurich.

Dry and hot up north

In contrast to the wet conditions, parts of Scandinavia continue to endure scorching temperatures, while smoke plumes from Siberia have affected air quality across the international dateline in Alaska. Unprecedented heat in western north America has also triggered devastating wildfires in recent weeks.

Among the Scandinavian countries enduring a lasting heatwave, the southern Finnish town of Kouvola Anjala, has seen 27 consecutive days with temperatures above 25C. “This is Finland, you know, it’s not Spain, it’s not north Africa,”, Ms. Nullis emphasised to journalists in Geneva.

“Certainly, when you see the images we’ve seen in Germany, Belgium and the Netherlands this week it’s shocking, but under climate change scenarios, we are going to see more extreme events in particular extreme heat,” the WMO official added.

Troubled waters

Concerns persist about rising sea temperatures in high northern latitudes, too, Ms. Nullis said, describing the Gulf of Finland in the Baltic Sea at a “record” high, “up to 26.6C on 14 July”, making it the warmest recorded water temperature since records began some 20 years ago.

Echoing a call by UN Secretary-General António Guterres to all countries to do more to avoid a climate catastrophe linked to rising emissions and temperatures, Ms. Nullis urged action, ahead of this year’s UN climate conference, known as COP26, in Glasgow, in November.

South Africa Invests in Biodiversity to Promote Rural Development and Conservation

Published

on

South Africa is stepping up investment for its wildlife and biodiversity sectors thanks to a grant of $8.9 million from the Global Environment Facility (GEF). The Catalyzing Financing and Capacity for the Biodiversity Economy Around Protected Areas Project aims to enhance South Africa’s stewardship of its rich biodiversity and expand the benefits of protected areas for local communities. It will also help address high unemployment and limited livelihoods options in and around protected areas as well as inequality in rural economies.

The project supports South Africa’s efforts to foster the unrealized potential of its wildlife and biodiversity sectors as drivers for economic growth, including through expanding conservation areas and mitigating threats to protected areas and conservation objectives.

It puts into action South Africa’s biodiversity economy node concept, which identifies certain areas within the country as containing both high-value biodiversity and opportunities for economic development. The project will target activities in three biodiversity economy nodes: (i) the Greater Addo to Amathole node in the Eastern Cape Province, (ii) the Greater Kruger-Limpopo node in Limpopo Province, and (iii) the Greater-iSimangaliso node in KwaZulu-Natal Province.

“The biodiversity economy is central to South Africa’s tourism industry and building the resilience of communities to climate change. Empowering communities to invest in the biodiversity economy will create jobs, promote biodiversity stewardship and stimulate rural development in a climate-smart way,” said Marie Françoise Marie Nelly, World Bank Country Director for South Africa, Botswana, Eswatini, Lesotho, and Namibia.

Project activities include providing training, mentorship, and capital to micro, small, and medium enterprises (MSMEs); expanding the area of land under protected status through South Africa’s land stewardship  program; and facilitating knowledge exchange to support expansion of the biodiversity economy across the country based on lessons learned from the three nodes.

The project is aligned with South Africa’s National Development Plan 2030 and its National Biodiversity Strategy and Action Plan 2015-2025, both of which identify the wildlife economy as an important sector for job creation and economic growth. It also supports South Africa’s climate change objectives and Nationally Determined Contribution to the Paris Climate Agreement. The project’s focus on inclusive job creation and economic growth through the development of MSMEs, integrated value chains, and entrepreneurship is also fully aligned with a draft World Bank Group Country Partnership Framework for South Africa.

About the Global Environment Facility

The Global Environment Facility (GEF) was established 30 years ago on the eve of the Rio Earth Summit to tackle our planet’s most pressing environmental problems. Since then, it has provided more than $21.5 billion in grants and mobilized an additional $117 billion in co-financing for more than 5,000 projects and programs. The GEF is the largest multilateral trust fund focused on enabling developing countries to invest in nature and supports the implementation of major international environmental conventions including on biodiversity, climate change, chemicals, and desertification. It brings together 184 member governments in addition to civil society, international organization, and private sector partners. Through its Small Grants Programme, the GEF has provided support to more than 25,000 civil society and community initiatives in 135 countries.
