50,000 wild species meet needs of billions worldwide; IPBES Report offers options to ensure sustainable use

70 per cent of the world’s poor are directly dependent on wild species. One in five people rely on wild plants, algae and fungi for their food and income; 2.4bn rely on fuel wood for cooking; and about 90 per cent of the 120mn people working in capture fisheries are supported by small-scale fishing. Overexploitation is one of the main threats to the survival of many land-based and aquatic species in the wild. The Report explores policies and tools that have been used in a variety of contexts with regard to the sustainable use of wild species.

50,000 wild species meet needs of billions worldwide; IPBES Report offers options to ensure sustainable use

Bonn, Germany

Billions of people in developed and developing nations benefit daily from the use of wild species for food, energy, materials, medicine, recreation, inspiration and many other vital contributions to human well-being. The accelerating global biodiversity crisis, with a million species of plants and animals facing extinction, threatens these contributions to people.

A new report by the Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) offers insights, analysis and tools to establish more sustainable use of wild species of plants, animals, fungi and algae around the world, says a press release from IPBES.  

The IPBES Assessment Report on the Sustainable Use of Wild Species is the result of four years of work by 85 leading experts from the natural and social sciences, and holders of indigenous and local knowledge, as well as 200 contributing authors, drawing on more than 6,200 sources. The summary of the Report was approved this week by representatives of the 139 member States of IPBES in Bonn, Germany.

“With about 50,000 wild species used through different practices, including more than 10,000 wild species harvested directly for human food, rural people in developing countries are most at risk from unsustainable use, with lack of complementary alternatives often forcing them to further exploit wild species already at risk,” said Dr Jean-Marc Fromentin (France), who co-chaired the Assessment with Dr Marla R Emery (USA/Norway) and Prof. John Donaldson (South Africa).      

“70 per cent of the world’s poor are directly dependent on wild species. One in five people rely on wild plants, algae and fungi for their food and income; 2.4bn rely on fuel wood for cooking; and about 90 per cent of the 120mn people working in capture fisheries are supported by small-scale fishing,” said Dr Emery. “But the regular use of wild species is extremely important not only in the Global South. From the fish that we eat to medicines, cosmetics, decoration and recreation, wild species’ use is much more prevalent than most people realize.”

The use of wild species is an important source of income for millions of people worldwide. Wild tree species account for two-thirds of global industrial roundwood; trade in wild plants, algae and fungi is a billion-dollar industry; and even non-extractive uses of wild species are big business. Tourism, based on observing wild species, is one of the main reasons that, prior to the Covid-19 pandemic, protected areas globally received 8bn visitors and generated $600bn every year.

The Report identifies five broad categories of ‘practices’ in the use of wild species: fishing; gathering; logging; terrestrial animal harvesting (including hunting); and non-extractive practices, such as observing. For each practice, it then examines specific ‘uses’ such as for food and feed; materials; medicine, energy; recreation; ceremony; learning and decoration – providing a detailed analysis of the trends in each, over the past 20 years. In most cases, the use of wild species has increased, but the sustainability of use has varied, such as in gathering for medicine and logging for materials and energy.  

Speaking specifically about fishing as an example, Dr Fromentin said: “Recent global estimates confirm that about 34 per cent of marine wild fish stocks are overfished and 66 per cent are fished within biologically sustainable levels – but within this global picture there are significant local and contextual variations. Countries with robust fisheries management have seen stocks increasing in abundance. The Atlantic bluefin tuna population, for instance, has been rebuilt and is now fished within sustainable levels.”  

“Overexploitation is one of the main threats to the survival of many land-based and aquatic species in the wild”, said Prof. Donaldson. “Addressing the causes of unsustainable use and, wherever possible reversing these trends, will result in better outcomes for wild species and the people who depend on them.”

The survival of an estimated 12 per cent of wild tree species is threatened by unsustainable logging; unsustainable gathering is one of the main threats for several plant groups, notably cacti, cycads and orchids, and unsustainable hunting has been identified as a threat for 1,341 wild mammal species – with declines in large-bodied species that have low natural rates of increase also linked to hunting pressure.

The Report identifies drivers such as landscape and seascape changes; climate change; pollution and invasive alien species that impact the abundance and distribution of wild species, and can increase stress and challenges among the human communities that use them. Global trade in wild species has expanded substantially in volume, value and trade networks over the past four decades.

Illegal use and illegal trade in wild species are also addressed in the Report – as this occurs across all of the practices and often leads to unsustainable use. The authors find that illegal trade in wild species represents the third-largest class of all illegal trade – with estimated annual values of up to $199bn. Timber and fish make up the largest volumes and value of illegal trade in wild species. 

As part of its analysis, the Report explores policies and tools that have been used in a variety of contexts with regard to the sustainable use of wild species. Seven key elements are presented, that could be used as levers of change to promote sustainable use of wild species if they are scaled up across practices, regions and sectors: (i) policy options that are inclusive and participatory; (ii) policy options that recognize and support multiple forms of knowledge; (iii) policy instruments and tools that ensure fair and equitable distribution of costs and benefits; (iv) context-specific policies; (v) monitoring of wild species and practices; (vi) policy instruments that are aligned at international, national, regional and local levels; maintain coherence and consistency with international obligations and take into account customary rules and norms; (vii) robust institutions, including customary institutions.

The Report concludes by examining a range of possible future scenarios for the use of wild species, confirming that climate change, increasing demand and technological advances are likely to present significant challenges to sustainable use in the future. Actions are identified for each practice that would help to address these challenges.

Speaking about the importance of the Report, Dr Anne Larigauderie, Executive Secretary of IPBES, said: “This Assessment was specifically requested by, among others, the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) and will inform decisions about trade in wild species at the 19th World Wildlife Conference in Panama in November.”
