| Outline of Research at the Start |
This research will focus on three key scientific questions. First, based on a state-of-the-art technology (remote sensing), what do the trajectories of global forest transitions over the past three decades signify; do they provide evidence for or against the forest transition theory? Second, what do the answers to Question 1 indicate; are we progressing towards the attainment of SDG 15, for example, in relation to Target 15.1? Third, where are the hot spots of forest cover loss and forest cover gain; are they stationary or changing spatially over time?

| Outline of Final Research Achievements |
The results revealed that over the past 60 years (1960-2019), the global forest area has declined by 81.7 million ha, with forest loss (437.3 million ha) outweighing forest gain (355.6 million ha). With this forest decline and the population increase (4.68 billion) over the period, the global forest per capita has decreased by over 60%, from 1.4 ha in 1960 to 0.5 ha in 2019. The spatiotemporal pattern of forest change supports the forest transition theory, with forest losses occurring primarily in the lower income countries in the tropics and forest gains in the higher income countries in the extratropics. Furthermore, economic growth has a stronger association with net forest gain than with net forest loss. To help achieve the sustainable development agenda (e.g., SDG 15), there is a profound need to reverse, or at least flatten, the global net forest loss curve by conserving the world’s remaining forests and restoring and rehabilitating degraded forest landscapes.

| Academic Significance and Societal Importance of the Research Achievements |
This research contributes to the study of the forest transition theory. The results highlight the need to address forest losses in the lower income countries especially in the tropics and for the higher income countries to reduce their dependence on imported tropical forest products.
