Around half of the Indian wildlife lives in the danger of being wiped out, the Living Planet Report 2016 has warned.
The report, which also identified India as an ecological black spot, mentioned that over 14,000 vertebrate populations of over 3,700 species from across the world highlights the pressure on water and land India faces because of unsustainable human activities.
Though India has about 4 per cent of the world's freshwater resources, ranking it among the top ten water rich countries, it is still designated a water stressed region.
70 per cent of its surface water is polluted and 60 per cent of groundwater sources are expected to be in a critical state within the next decade, the report prepared by World Wide Fund for nature (WWF) with other research institutions said.
Quoting factsheets about India based on reference material sources from public domains, it said 41 per cent of mammals, 7 per cent of birds, 46 per cent of reptiles, 57 per cent of amphibians and 70 per cent of freshwater fish of India's wildlife is threatened with extinction while four of the 386 species of mammals evaluated are already extinct.
Although India aims for 33 per cent forest cover, it currently has only 21.3 per cent of forest and tree cover which makes it one of the countries with the lowest per capita availability of forests in the world, according to the factsheets.
According to the reference material, it is estimated that by 2020, food grain requirement will be almost 30-50 per cent more than the demand in 2000 and India could also see a 10-40 per cent loss in crop production by 2080-2100 due to global warming.
The global wildlife populations could also decline by two-thirds by 2020, the report said.
The report said that food production to meet demands of growing human population was the "primary" factor responsible for the destruction of habitats and over-exploitation of wildlife.
It said despite the low personal carbon footprint of Indians, it is a "challenge" when aggregated by population size and predicted that the equation will be further affected as wealth grows.
“Global wildlife populations could decline by an average of 67 per cent between 1970-2020 as a result of human activities. Global populations of birds, mammals, amphibians, fish and reptiles have already declined by 58 per cent between 1970 and 2012, the most recent year with available data. This places the world on a trajectory of a potential two-thirds decline within a span of the half-century ending in 2020,” the report said.
The report said just as human demand on nature varies among countries, nature's biocapacity--ecosystem's capacity to produce resources such as food, fibre and renewable raw materials and absorb spillover wastes like carbon dioxide--is unevenly distributed.
"Brazil, China, US, Russia and India account for nearly half of the planet's total biocapacity. These few countries function as global biocapacity hubs as they are among the primary exporters of resources to the other countries. This results in great pressure on ecosystems in these countries, undoubtedly contributing to habitat loss. This is an example where pressure is driven by consumption activities in other, distant countries," it said.
The 2016 report noted that food production is primarily responsible for the destruction of habitats and over- exploitation of wildlife.
"At present, agriculture occupies about one-third of the Earth's total land area and accounts for almost 70 per cent of water use. India ranks fifth in terms of biocapacity...India's carbon footprint currently makes up 53 per cent of the country's overall ecological footprint," the report said.
The report, which tracks over 14,000 vertebrate populations of over 3,700 species from 1970 to 2012, provides additional evidence that the planet is entering a completely unchartered territory in history in which humanity is shaping changes on Earth, including "a possible sixth mass extinction".
The top threats to species are directly linked to human activities, including habitat loss, degradation and over- exploitation of wildlife, the report said.
"Our consumption patterns and the way we look at our natural world are constantly shaping the future of our planet... The power to build a resilient planet for future generations lies in our understanding of how we are moving into this new epoch that scientists are calling 'Anthropocene' and adopting sustainable practices that decrease humanity's impact on the planet. We need to come together as a global community and address the threats to biodiversity to protect our environment as well as our economic and social structures," said Ravi Singh, Secretary General and CEO, WWF-India.
In 2020, commitments made under the Paris Climate deal will kick in and the first environmental actions under the globe's new sustainable development plan are due that year.
"Wildlife is disappearing within our lifetimes at an unprecedented rate...Biodiversity forms the foundation of healthy forests, rivers and oceans. Take away species, and these ecosystems will collapse along with the clean air, water, food and climate services that they provide us," said Marco Lambertini, International Director General, WWF.
The report recognizes the 2030 Agenda for Sustainable Development as an "essential" guide to decision-making that can ensure that the environment is valued alongside economic and social interests.
