    It took scientists more than three decades to transform a perceived desertification crisis in the Sahel into a non-event. Looking beyond the Sahel, the chapters in this book provide case studies from around the world that examine the use and relevance of the desertification concept.

    Cattle grazing and fire are common types of management on natural ecosystems, generating several threats to the conservation of native vegetation (e.g., changes in species richness, cover, and abundance, mainly of bovine-palatable species). In this work, we analysed the response of the structure and composition of vegetation managed with different cattle stocking rates and fire in the savanna ecosystems of Colombia. The study was located in the eastern area of the Llanos region, where savannas were subjected to grazing and burning.

    The stabling of livestock farming implies changes in both local ecosystems (regeneration of forest stands via reduced grazing) and those located thousands of kilometers away (deforestation to produce grain for feeding livestock). Despite their importance, these externalities are poorly known. Here we evaluated how the intensification and confinement of livestock in Spain has affected forest surface changes there and in South America, the largest provider of soybeans for animal feed to the European Union.

    Discussions about climate change have repeatedly regarded livestock as responsible for a significant contribution of greenhouse gas emissions. However, proper management schemes for livestock production may contribute to a reduction in emissions and, at the same time, induce optimization of production systems and intensification of food production.

    Nine Latin American countries plan to use silvopastoral practices—incorporating trees into grazing lands—to mitigate climate change. However, the cumulative potential of scaling up silvopastoral systems at national levels is not well quantified. Here, we combined previously published tree cover data based on 250 m resolution MODIS satellite remote sensing imagery for 2000–2017 with ecofloristic zone carbon stock estimates to calculate historical and potential future tree biomass carbon storage in Colombian grasslands.

    Soil management in the Altillanura of Colombia’s Eastern Plains The strategies used for adequate soil management for the Altillanura (high plains with flat topography) of Colombia’s Eastern Plains are reviewed to establish modern, efficient, and sustainable livestock systems in this region. Advances in technology development within the technical and scientific cooperation agreement signed between Colombia’s Ministry of Agriculture and Rural Development (MADR) and CIAT, as well as those of the Center’s Soils Project and several national institutions co-partners in the agreement.

    There are many options for enhancing food production from fish in managed aquatic systems.The most appropriate technology, however, will vary from place to place, and the conditions under which one technology is prefered over another are still not well defined.

    As Diretrizes Voluntárias sobre a Governança Responsável da Posse da Terra, das Pescas e das Florestas no Contexto da Segurança Alimentar Nacional mencionam explicitamente os pastores como utilizadores das Diretrizes e como alvos de capacitação. Apesar da marginalização histórica e muitas vezes contínua dos pastores, este guia técnico foi desenvolvido em resposta às oportunidades emergentes para apoiar os pastores e para reforçar os seus direitos à terra e aos recursos.
