have proposed a time-bound, science-based policy, titled “A Global Deal for
Nature (GDN)”, to save the diversity and abundance of life on Earth. The study
has been published in the journal Science
The policy’s mission is to save the diversity
and abundance of life on Earth—for the price tag of $100 billion a year.
The first major goal of GDN is to protect
biodiversity by conserving at least 30% of the Earth’s surface under the UN
Convention on Biological Diversity by 2030. However, as much more of Earth’s
natural ecosystems need to be preserved or restored in order to avert impacts of
global warming, GDN calls to protect another 20% of the Earth as Climate
Stabilization Areas (CSAs).
Secondly, GDN aims to mitigate climate change by
conserving the Earth’s natural carbon storehouses.
Thirdly, it seeks to reduce major threats such
as meeting 2050 world food demand by directing cropland expansion to degraded
lands and reducing food waste; or reduce use of plastics or ecologically
damaging toxins etc.
Conservation scientists, environmental NGOs have
urged governments to adopt the GDN as a companion commitment alongside the
Paris Climate Agreement. The Paris agreement (2015), an international agreement
seeks to combat climate change and accelerate the actions and investments
needed for a sustainable low carbon future.
The GDN campaign is being driven by One Earth,
an initiative of the Leonardo DiCaprio Foundation. The foundation seeks to organize
support from international institutions, governments, and citizens globally to
support ambitious conservation goals. One Earth has launched an online petition
drive to build popular support for GDN.
