Living Planet Report 2022: Wildlife Populations decline by 69% in 50 years

There has been a 69 per cent decline in the wildlife populations of mammals, birds, amphibians, reptiles and fish, across the globe in the last 50 years, according to the latest Living Planet Report by World Wide Fund for Nature (WWF).

What The Report Highlighted:

Biodiversity loss and climate crisis should be dealt with as one instead of two different issues as they are intertwined, the international wildlife conservation organisation said in the report, highlighting the link between the two issues for the first time. The highest decline (94 per cent) was in the Latin America and the Caribbean region, the report released October 13, 2022 showed.  Africa recorded a 66 per cent fall in its wildlife populations from 1970-2018 and the Asia Pacific 55 per cent, according to the WWF report. Freshwater species populations globally reduced by 83 per cent, confirming that the planet is experiencing a “biodiversity and climate crisis”, the organisation found. Habitat loss and barriers to migration routes were responsible for about half of the threats to monitored migratory fish species, it noted.

The Main Threats:

WWF identified six key threats to biodiversity — agriculture, hunting, logging, pollution, invasive species and climate change — to highlight ‘threat hotspots’ for terrestrial vertebrates. A nature-positive future needs transformative, game-changing shifts in how we produce, how we consume, how we govern and what we finance,” mentioned in the report. It is clear that unless we stop treating these emergencies as two separate issues, neither problem will be addressed effectively.

Loss Of Habitat & India:

The Living Planet Index (LPI), featuring about 32,000 populations of 5,230 species across the world, showed that vertebrate wildlife populations are plummeting at a particularly staggering rate in tropical regions of the world. Mangroves continue to be lost to aquaculture, agriculture and coastal development at a rate of 0.13 per cent per year, according to the findings. Many mangroves are also degraded by overexploitation and pollution, alongside natural stressors such as storms and coastal erosion, added the report. Mangrove-loss represents loss of habitat for biodiversity and the loss of ecosystem services for coastal communities, it read.

“In some locations, it can mean the loss of the very land where coastal communities live,” it read. Around 137 square kilometres of the Sundarbans mangrove forest in India and Bangladesh has been eroded since 1985, reducing land and ecosystem services for many of the 10 million people who live there, the analysis showed. “Climate change in India will impact key areas, such as water resources, agriculture, natural ecosystems, health and the food chain,” Ravi Singh, secretary-general and chief executive, WWF India, said.

He talked about the need for an all-inclusive collective approach that can put us on a more sustainable path and ensures that the costs and benefits from our actions are socially just and equitably shared.
