Geomorphometry is the science of quantitative land-surface analysis. It draws upon mathematical, statistical, and image-processing techniques to quantify the shape of earth's topography at various spatial scales. The focus of geomorphometry is the calculation of surface-form measures (land-surface parameters) and features (objects), which may be used to improve the mapping and modelling of landforms to assist in the evaluation of soils, vegetation, land use, natural hazards, and other information. This book provides a practical guide to preparing Digital Elevation Models (DEM) for analysis and extracting land-surface parameters and objects from DEMs through a variety of software. It further offers detailed instructions on applying parameters and objects in soil, agricultural, environmental and earth sciences. This is a manual of state-of-the-art methods to serve the various researchers who use geomorphometry.Soil scientists will use this book to further learn the methods for classifying and measuring the chemical, biological, and fertility properties of soils and gain a further understaing of the role of soil as a natural resource. Geologists will find value in the instruction this book provides for measuring the physical features of the soil such as elevation, porosity, and structure which geologists use to predict natural disasters such as earthquakes, volcanoes, and flooding. - Technical details on a variety of software packages allow researchers to solve real-life mapping issues - Provides soil and agronomy researchers best practice techniques for soil data analysis to assist in enhanced land-use and planning - Offers geologists essential tactics for better environmental management by providing a comprehensive analysis of the physical features of soil - Companion website includes access to the latest technological advancements previously unpublished in any other comprehensive source: geomorphometry software, DEM data sources, and applications

This book discusses the Lagoa Santa Karst, which has been internationally known since the pioneering studies of the Danish naturalist Peter Lund in the early 1800s. It covers the speleogenesis, geology, vegetation, fauna, hydrogeology, geomorphology, and anthropogenic use of the Lagoa Santa Karst and is the first English-language book on this major karst area. The area, which has been at the heart of the debate on the origin and age of human colonization in the Americas, is characterized by a classical and scenic karst landscape with limestone cliffs, karst lakes and karst plains, in addition to numerous solution dolines. More than 1,000 caves have been documented in the area, many with significant archeological and paleontological value. Despite its great importance, the Lagoa Santa Karst faces severe environmental threats due to limestone mining and the expansion of the metropolis of Belo Horizonte and its surrounding towns. The growing recognition of the area’s remarkable significance has led to increasing concern, and a number of protected areas have now been established, improving the conservation status of this landmark karst area.

This book presents Brazil as a country of continental dimensions. Its territory has a large variety of rock types, geological structures and climates. The country has a large variety of landscapes, such as the humid plains of the Amazon River, the dry plateaus of the semi-arid region or the subtropical mountains of the southern region. On the coast, some plateaus and mountains, like the Serra do Mar Mountain range, formed a significant barrier front to access the hinterland of Brazil. On the other side of these coastal plateaus and mountains, there is a large collection of other plateaus, mountains, plains and depressions little altered by human interference. Thus, Brazil has a unique variety of different landscapes and extraordinary geomorphological sites. The book invites readers to learn more about the beautiful Brazilian landscapes, their complexity and vastness.

This book is a pioneer attempt to bring forward the first synthesis on the most diverse and threatened mountain top vegetation of South America, the rupestrian grasslands. It brings to light the state of the art information on this ecosystem geology, soil formation and distribution, environmental filters that lead to biodiversity, species interactions and their fine tuned adaptations to survive the harsh mountain environment. The human dimensions of the rupestrian grassland are also addressed, including the anthropogenic threats that may irreversibly impact biodiversity and ecosystem services. The book also highlights the ongoing studies on ecological restoration and first attempt to model the impacts of climate change on its speciose biota.
