Japanese researchers studied the global land use data set to see how global forests have changed in space and time, and found that from 1960 to 2019, total forest loss , as a result of which the total forest area has decreased by 81.7 million ha.
Researchers note that, together with the increase in the Earth ' s population, this has led to a significant reduction in the number of forests per capita, which has declined by more than 60 per cent, from 1.4 hectares in 1960 to 0.5 hectares in 2019.
The authors also confirmed the theory of forest transition, suggesting that the loss of green cover occurs mainly in low-income tropical countries and that growth occurs in higher-income countries outside tropical regions; the study confirmed this hypothesis.
Researchers believe that significant changes in forest cover have an impact on ecosystem integrity and biodiversity, and it also affects the lives of at least 1.6 billion people, mainly in developing countries, whose lives are in varying degrees linked to forest wealth.
Despite this spatial picture of forest loss, mainly in the less developed countries, the impact of the more developed countries on forests also needs to be studied in depth, and with the increased protection of forests in the more developed countries, forest losses are moving to the less developed countries, especially in the tropics.
