The book provides a fundamental introduction to the zonal division of the Earth based on natural and agricultural aspects. The concept presented here for the spatial organization and content formulation of the zones takes new approaches and considers modern ecological research. The representation of soils is based on the latest soil classification standards, thus offering important information for global differentiation according to utilization potentials. The land area is divided into ecozones. A general section precedes the regional part, introducing key terms and methods of ecosystem research. A dedicated chapter focuses on climate change and its impact on the ecozonal division of the Earth. Each chapter addresses the main sections: - Distribution - Climate - Relief and Water Bodies - Soils - Vegetation and Wildlife - Land Use.
