It discusses the alarming rate of deforestation and degradation caused by agricultural expansion, logging, and climate change, and highlights the importance of sustainable forestry practices for conservation. The author, with over thirty years of experience in tropical forest ecology, presents a comprehensive analysis of selective logging, its impacts, and proposes strategies for sustainable management that benefit both the environment and local populations. The book is intended for researchers, policymakers, and those interested in environmental conservation.Generated by AI.Essais SeriesSustainable forestryGenerated by AIForest conservationGenerated by AISustainable forestryForest conservationSist Plinio1312065MiAaPQMiAaPQMiAaPQBOOK9910886968103321Exploiter Durablement les forêts Tropicales4254623UNINA
