Nature-based solutions (NBS) can contribute to our fight against climate change by the end of the century. Discussions of being net zero usually refer to ‘nature-based solutions’ (NBS) or nature-dependent methods to reduce carbon. Such as protecting and growing forests because they absorb carbon or because of this, the initiative to plant trees on a large scale.
But there is little possibility of limiting global warming with these methods. According to a new Oxford research published today in ‘Nature’, ‘Nature-based solutions’ (NBS) can contribute to our fight against climate change by the end of the century. The analysis shows that, to limit the increase of global warming, we have to reduce emissions, for this the need for good management and restoration of nature as well as NBS investment should increase so that ecosystems and land for the future I will improve.
The Oxford team found that with the NBS measures, which include the protection of ecosystems and its large-scale restoration, and improving land management, global warming will reduce 0.1 ° C rather than 1.5 ° C and if the target is 2.0 ° C, then The measures will reduce global warming by only 0.3 degrees Celsius.
This will only be achieved when, after 2025, more than 10 gigatonnes of CO 2 per year will be eliminated, higher than the annual emissions of the global transportation sector at a cost of less than $ 100 per tonne of CO2.
The important thing in this is that, ‘Nature-based solutions’ (NBS) can keep the earth cool even after reaching an extreme temperature. According to the researchers NBS can reduce global warming by 0.1 ° C by 2055 and 0.4 ° C by 2100, even under better conditions. But, based on this estimate, only a small portion of the current climate change spending is paid for ‘Nature-Based Solutions’ (NBS).
According to Cécile AJ Girardin, technical director of Nature Based Solutions Initiative, Oxford, ‘the world must now invest in nature-based solutions that are ecologically correct, socially just, and have many benefits to society over a century or more Are designed to deliver. Properly managed, restored and sustainable management can benefit many generations to come from the preservation of our working land. ‘
‘Nature-based solutions’ (NBS) are beneficial for both human welfare and biodiversity and work with nature to meet social challenges, and they are based on the COP 26 Climate Change Conference held in November has been made .
According to co-author Professor, Yadvinder Malhi, Oxford Professor of Ecosystem Science, ‘The more ambitious the climate targets are, the less time such solutions can be achieved that will also impact peak warming.’
Professor Miles Allen says, ‘Although corporate claims of ambitious climate targets, but medium-term plans that rely on the NBS as an alternative to reducing fossil fuel emissions are not just a heap.’
But, the report warns, wildfires and other ecological losses could reduce the effectiveness of ‘nature-based solutions’ (NBS) if global warming is not investigated. Therefore, their long-term carbon sink potential and biodiversity, equity and the United Nations Sustainable Development Goals (SDGs) and their impacts should be given full attention. It also means that global warming should be limited through other methods, to the geological storage decarbonization of CO 2.
The authors also call for increased investment considering the mixed and long-term benefits of NbS using metrics with rigorous evaluation of activities.
The co-author of this report, Professor Nathalie Seddon, founder Oxford’s director of Nature-Based Solutions’ (NBS), concludes that ‘an ambitious scaling-up nature-based solutions’ (NBS) can be quickly but cautiously There is a need to implement, which in a way supports the biodiversity and the rights of the local people, while keeping the fossil fuels stable. ‘
