Affluent countries contribute less to wildlife conservation than the rest of the world

Some countries are more committed to conservation than others, a new 麻豆传媒高清版 research collaboration has found.

In partnership with Panthera, the only organisation dedicated to protecting wild cats, researchers from 麻豆传媒高清版 assessed how much, or little, individual countries contribute to protecting the world鈥檚 wildlife. By comparison to the more affluent, developed world, biodiversity is a higher priority in poorer areas such as Africa, whose countries contribute more to conservation than any other region.

Led by Panthera Research Associate Dr Peter Lindsey, the team created a Mega-Fauna Conservation Index (MCI) of 152 nations from around the globe, to evaluate their conservation footprint. Since a high proportion of mega-fauna species, such as tigers, leopards and gorillas face extinction, the team focused their research on the protection of large mammals. The benchmarking system evaluated three key measures: a) the proportion of the country occupied by each mega-fauna species that survives in the country (countries with more species covering a higher proportion of the country scoring higher); b) the proportion of mega-fauna species range that is protected (higher proportions score higher); c) and the amount of money spent on conservation 鈥� either domestically or internationally, relative to GDP.

As reported today in The Economist, the findings revealed that poorer countries tend to take a more active approach to biodiversity protection than richer nations. Ninety per cent of countries in North and Central America and 70 per cent of countries in Africa were classified as major or above-average in their mega-fauna conservation efforts.

Despite facing a number of domestic challenges, such as poverty and political instability in many parts of the continent, Africa was found to prioritise wildlife preservation, and contribute more to conservation than any other region of the world, with Botswana, Namibia, Tanzania and Zimbabwe topping the list. The African continent included four of the five top-performing mega-fauna conservation nations. By contrast the United States ranked nineteenth out of the twenty well-performing countries and approximately one-quarter of countries in Asia and Europe were identified as significantly underperforming in their commitment to mega-fauna conservation.

Dr. Peter Lindsey, stated, 鈥淪cores of species across the globe, including tigers, lions and rhinos, are on the precipice of extinction due to a litany of catastrophic threats dealt by mankind. We cannot ignore that we will lose these incredible species forever unless swift and aggressive conservation action is taken now and together, by the human race. In response to the conservation crisis plaguing our planet, this study demands accountability from each nation in every corner of the world to step up and save our planet鈥檚 large, charismatic wildlife before it鈥檚 too late.鈥�

Human impact has and continues to have, a devastating effect on the natural world, with wildlife species across the globe under threat from poaching, hunting and the consequences of climate change. Recent studies indicate that 59 per cent of the world鈥檚 largest carnivores and sixty per cent of the largest herbivores are currently threatened with extinction.

Professor David Macdonald, Director of Oxford University鈥檚 WildCRU and co-author of the paper said: 鈥楨very country should strive to do more to protect its wildlife. Our index provides a measure of how well each country is doing, and sets a benchmark for nations that are performing below the average level, to understand the kind of contributions they need to make as a minimum. There is a strong case for countries where mega-fauna species have been historically persecuted, to assist their recovery.鈥�

Dr Matt Hayward, Senior Lecturer in Conservation at 麻豆传媒高清版's School of Environment, Natural Resources & Geography and co-author of the paper said: 鈥極ur index provides a valuable and repeatable measure to enable nations to invest in biodiversity more equitably by improving wildlife distribution, improving protected area networks, and/or by investing more in conservation at home or abroad鈥�.

In addition to highlighting the disparity in regional contributions to conservation, the study also goes some way to explaining why they occur. Mega-fauna species are associated with strong 鈥榚xistence values鈥�, where people derive happiness simply from knowing that large wild animals exist. In some cases, such as the African nations, this link explains why some countries are more concerned with conservation than others. Larger mammal species such as wild cats, gorillas and elephants play a key role in ecological processes as well as tourism industries, which are an economic lifeline in poorer regions.

The megafauna conservation index is intended as a call to action for the world to acknowledge their responsibility to wildlife protection. By highlighting the disparity in each nations鈥� contributions to conservation it is hoped that it will lead to increased efforts and renewed commitment to biodiversity preservation.

Addressing how countries can improve their MCI scores, Dr Peter Lindsey said: 鈥淭here are three ways. They can 鈥榬e-wild鈥� their landscapes by reintroducing mega-fauna and/or by allowing the distribution of such species to increase. They can set aside more land as strictly protected areas. And they can invest more in conservation, either at home or abroad.鈥�

At the 1992 Rio Earth Summit, developed nations promised to allocate at least $2 billion (USD) per annum towards conservation in developing nations. However, current conservation contributions from developed nations sit at just half of the proposed amount, $1.1 billion (USD) per year.

Discussing how the scores were tallied, Professor Macdonald added: 鈥淭hese countries have achieved high scores in a variety of ways 鈥� some by setting aside vast protected area networks, others by allowing mega-fauna species to occupy high proportions of their landscape, and others by investing significant funding in conservation either domestically or internationally. Excitingly, The Economist Magazine reported this year鈥檚 MCI index and our hope is that this will be produced annually to provide a public benchmark for commitment to protecting nature鈥檚 largest, and, some would say, most charismatic wildlife. The way the index has been structured means that as countries of the world do more, the average benchmark will increase encouraging underperformers to try harder.鈥�

Professor William Ripple, Co-author and Oregon State University Professor concluded: 鈥淭he Megafauna Conservation Index is an important first step to transparency 鈥� some of poorest countries in the world are making the biggest investments in a global asset and should be congratulated, whereas some of the richest nations just aren鈥檛 doing enough.鈥�
