Approximately 30% of the land is covered by forest, however, this number is rapidly declining due to deforestation. Human population growth is putting pressure on forests for timber, and land is increasingly cleared for expanding agriculture and urban settlements. The loss of forests has far-reaching impacts, threatening biodiversity and degrading ecosystems, as air and water quality - and even the climate - are affected. This collection assembles the latest research in monitoring deforestation and its impacts, which is critical for effective conservation and forest management.
