India has seen significant expansion of tropical dry woodlands over the past decade, but new satellite analysis shows that increased tree cover does not necessarily mean native forests are recovering.A study of forestland changes between 2014 and 2024 found that India has added approximately 2.1 million hectares (approximately 5.2 million acres) of tropical dry forestland, an area larger than the size of Wales, highlighting the impact of large-scale tree planting and ecological restoration operations.However, the study also pointed out that there are complex structures behind these increases, and national tree cover statistics alone cannot reflect the true status of native dry forests.
The research team used high-resolution satellite imagery to carefully track changes in tropical dry forestlands in India over a decade. This type of ecosystem is widely distributed, but has received relatively limited scientific research and protection attention compared to tropical rainforests. The analysis results show that forest land across the country is generally increasing, and a considerable part of the increase is related to government-led ecological restoration plans, including the "Green India Mission", the "Compensatory Afforestation Fund" and the "National Afforestation Program". The study believes that these policy tools have left a clear "imprint" on the landscape.
However, from the perspective of land types and management entities, forestland expansion shows obvious differences. Within government-managed forest lands, new growth is often associated with conservation and restoration projects that extend forest cover and support emissions reduction and climate goals. Outside of government forest lands, a large number of new trees come mainly from commercial timber plantations and commercial tree crop planting areas embedded in agricultural landscapes. Therefore, in the statistical sense of "increase in forest land", there are forests formed by ecological restoration, as well as artificial forests and agricultural and forestry complex plots that mainly provide economic benefits.
The study highlights that India's tropical dry woodlands are critical but often overlooked ecosystems in their own right. Such woodlands provide habitat for wildlife, have important carbon storage capabilities, and support the livelihoods of millions of residents, especially economically disadvantaged rural communities. Researchers pointed out that it is necessary to figure out what types of forest lands are expanding and in what spatial and property rights patterns the expansion occurs. This has practical significance for biodiversity protection, climate policy formulation and the interests of local communities.
An important caveat is that increases in tree cover at the national level do not necessarily mean native forests are recovering. During the study period, some native tropical dry forestlands continued to decline, even within protected areas or government-managed forest lands. Although artificial forests and commercial forests can provide economic value and contribute certain climate benefits in terms of carbon absorption, scientists emphasize that they often cannot replace the long-term evolution of natural woodlands in terms of species diversity, ecological processes, and overall ecological functions.
In terms of methodology, the research team used satellite data to reconstruct the map of changes in forest land cover in India from 2014 to 2024, and analyzed the specific locations of forest land expansion and disappearance at extremely fine spatial scales. This technical approach allowed them to distinguish trends across different landscapes and land tenure types, identifying areas where forestland expansion was driven by restoration projects and where plantation growth was driven by commercial plantings.
Dhanapal Govindarajulu, the first author of the paper, said that there has been a "significant increase" in India's dry forest land cover overall in the past decade, a large part of which is related to large-scale restoration and afforestation programs, which shows the potential power of government policies in promoting changes in ecological patterns. But he also emphasized that "not all forestland growth has the same ecological significance." If we only stay at the national level of tree coverage data, we may ignore the actual changes in native ecosystems on the ground.
At the global level, many countries are committing to large-scale tree planting and forest restoration as important measures to address climate change and biodiversity loss. The researchers point out that this analysis of India shows that a mere "number report card" is not enough to judge whether a repair is truly successful. To assess whether new tree cover is having the intended effect, policymakers and the scientific community need to answer further questions: Whether these additional forest lands are protecting natural ecosystems, truly supporting wildlife habitat, and whether they are actually improving the living conditions of neighboring communities.
