The European Commission’s Joint Research Centre and FAO's Global Soil Partnership collaborated with experts from across Asia and other regions to produce the first-ever Soil Atlas of Asia. The aim of the Atlas is to raise awareness about the significance of soil to life in Asia among a wide range of audiences, including the general public, decision makers, politicians, teachers, and scientists from other disciplines. The Atlas comprises a series of annotated maps that demonstrate the diversity of soil characteristics across Asia in an easy-to-understand manner. It also explains how soils are formed, the key factors that shape soil characteristics, and why these vary across the continent. Moreover, the Atlas emphasizes the role of soils in shaping our daily lives and highlights the growing pressures on soils resulting from urban expansion, inappropriate land management, pollution, increased demand for food, and climate change. The Atlas encourages people to understand how their actions can help protect and restore soils while reducing degradation processes.
