Uzbekistan's 2021 pledge to plant 1 billion trees was followed in 2022 by reports that 6.2M 'planted' trees were never registered and 2.4M seedlings died from neglect; UNDP then co-developed a digitised master plan now tracking hundreds of millions of trees.
In November 2021 Uzbekistan launched 'Yashil Makon', pledging 1 billion trees over five years and raising tree cover from 8% to 30%.
Daryo.uz investigative reporting (Oct 2022) found 6.2 million 'planted' trees were never registered, 2.4 million seedlings died from neglect, and 341,000 were planted on unsuitable land.
The Ministry of Ecology partnered with UNDP on a 2023 feasibility study/master plan accounting for survival rates and site-selection standards, and a digitisation effort held records for over 250 million individual trees by January 2024.
