Global Change is increasingly considered a critical topic in environmental research. Remote sensing methods provide a relevant tool to monitor global variables, since they offer a systematic coverage of the Earth Surface, at different spatial, spectral and temporal resolutions. The data provided by Earth Observation Satellites are being operationally used for monitoring atmospheric conditions, ice sheets and glaciar movements, crop dynamism and land use changes, deforestation and desertification processes, as well as water conditions. The book includes an analysis of the leading missions in global Earth observation, and then reviews the main fields in which remote sensing methods are providing vital data for global change studies. Audience: Academic libraries, practitioners, professionals, scientists, researchers, lecturers, tutors, graduates, undergraduates
Peasant and Nation offers a major new statement on the making of national politics. Comparing the popular political cultures and discourses of postcolonial Mexico and Peru, Florencia Mallon provides a groundbreaking analysis of their effect on the evolution of these nation states. As political history from a variety of subaltern perspectives, the book takes seriously the history of peasant thought and action and the complexity of community politics. It reveals the hierarchy and the heroism, the solidarity and the surveillance, the exploitation and the reciprocity, that coexist in popular political struggle. With this book Mallon not only forges a new path for Latin American history but chall...
Competitiveness describes a key ability important for plants to grow and survive abiotic and biotic stresses. Under optimal, but particularly under non-optimal conditions, plants compete for resources including nutrients, light, water, space, pollinators and other. Competition occurs above- and belowground. In resource-poor habitats, competition is generally considered to be more pronounced than in resource-rich habitats. Although competition occurs between different players within an ecosystem such as between plants and soil microorganisms, our topic focusses on plant-plant interactions and includes inter-specific competition between different species of similar and different life forms and...
