Planting Trees ! Not Enough !

The special report on Climate Change and Land released on August 8, 2019, by the Intergovernmental Panel on Climate Change (IPCC) illustrates this difficulty. It delivers a wake-up call for policymakers — that aggressive forestry targets do not excuse cowardice in cutting emissions from fossil fuel use. To make this case, it explicitly identifies the limits of carbon sequestration by forests.

Quick summary by Maggubhai

  • We always think that more forestation means more carbon absorptions but a recent study has found several issues with this statement.
  • The report on Climate Change and Land released by the Intergovernmental Panel on Climate Change (IPCC) demonstrates the issues regarding the relationship between the above two and also draws the flaws of land-based mitigation techniques.
  • The report says some land-based approach takes decades to provide desirable results as these approaches are directly linked to the growth rates of trees.
  • Besides forestation agroforestry cannot contribute indefinitely in carbon absorption eventually the net annual removal of CO2 from the atmosphere declines towards zero.
  • The report warns that the consequences of not taking steps to mitigate climate change immediately may exceed the costs of immediate action in many sectors.
  • The report also clarifies being inactive in reducing industry-formed Green House gases will lead to significant economic damage to many countries in many regions of the world.
  • IPCC thinks bioenergy carbon capture and storage (BECCS) is also not a preferred solution.
  • The report explicitly divides solutions into two categories – those which contribute positively to sustainable development and other societal goals and those which increase demand for land conversion.
  • In a gist the report clarifies and also warns policymakers about the land-based mitigation approaches to tackle carbon emissions hence shifts as well as seeks attention to make more collaborative initiatives.
