Book Description
More than a simple monograph, the authors present a comprehensive geomorphic overview of a large tropical region where they show how deciphering the long-term landform evolution helps understanding the present set of landscapes and morphodynamic environments. The Equatorial margin of the Brazilian “Nordeste” displays stratigraphic landmarks whose interpretation reveals the age and nature of landforms, leading to a reconstruction of the geomorphic history by the means of combined morphostratigraphic and morphopedological approaches. Beyond the role of differential erosion related to moderate post-oceanic opening uplift, the plain and upland landscape reflects a juxtaposition of landform and soil generations related to a shallow basin inversion, the last stages of which occurred in semi-arid conditions since the Oligocene. These results throw light on old debates on models of long-term landform development in platform areas, and also help evaluating recent models of denudation and burial based on thermochronological methods.

Book Description
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.

Book Description
This book presents extensive and new information on the geomorphology of cratonic areas of southern South America. It includes valuable data relating to recurrent controversies in general geomorphology beyond the boundaries of South America and reveals the great need to integrate many different aspects of geomorphology in regional studies. With the focus on ancient landscapes and especially on planation surfaces it addresses the question of what processes could form such huge features, and how they can be preserved for so long. Many of the papers include maps of planation surfaces or other geomorphic units. The volume brings together an up-to-date, state-of-the-art collection of information on South American geomorphology, and shows beyond doubt that geomorphology is on the same time scale as global tectonics, biological evolution and major climate change. Some of the papers describe ancient geomorphological features of areas that have never been studied or published before, while others describe regions which are totally unknown to the public. The scope of the book extends from tropical latitudes north of the Tropic of Capricorn, south to freezing Patagonia in the “roaring fifties”, more than 3,500 km from north to south. Including over one thousand citations from geological and geomorphological literature, this volume will serve as a starting point for a whole new phase of studies of the fascinating landscape history of southern South America.

Book Description
This book provides an overview of the tropical marine environments of Brazil and a multi-disciplinary assessment of the impact of ongoing climate change in these environments. These changes will affect physical, biological and biogeochemical characteristics of coastal zones and oceans, modifying their ecological structure, their functions and the various services provided to humans and have the potential of causing severe socioeconomic impacts in local (coastal zone), regional (continental shelf and shallow seas) and global (ocean) scales. The Tropical Brazil presents a unique opportunity to evaluate how spatial and temporal heterogeneity influences the response and resilience of marine environments to climate changes. This region comprises the main reef constructions of the Western South Atlantic Ocean, the majority of the Brazilian deltas, one of the longest mangrove areas of the world, a very narrow and shallow continental shelf, extreme variations in sediment and nutrient flows, as well as undeniable importance in transferring heat and mass between hemispheres.

Book Description
The West African margin has enjoyed a rich and varied exploration history, remaining an exciting region for hydrocarbon discovery. Fusion of traditional approaches, imaginative ideas, leveraged with modern technologies is still yielding success. This volume examines the margin from regional to pore-scale, from surface-processes to deep crustal levels, drawing on input from academia and industry.

Book Description
This book presents the main drivers of benthic structure and processes in estuaries from the 8,000 km-Brazilian coast, assesses the influence of natural and human disturbance, and discusses their ecological importance and management needs. Estuaries are unique coastal ecosystems often with low biodiversity that sustain and provide essential ecological services to mankind. These ecosystems include a variety of habitats with their own sediment and fauna dynamics, all of them globally altered or threatened by human activities. Mangroves, saltmarshes, tidal flats and other confined estuarine systems are under increasing stress by overfishing and other human activities leading to habitat and species loss. Combined changes in estuarine hydromorphology and in climate pose severe threats to estuarine ecosystems at a global scale.

Book Description
Physical landscapes are one of the most fascinating facets of our Planet, which tell stories about the evolution of the surface of the Earth. This book provides up-to-date information about the geomorphology of the selected ‘classic’ sites from around the world and shows the variety of geomorphological landscapes as moulded by different sets of processes acting over different timescales, from millions of years to days. The volume is written by nearly fifty geomorphologists from more than twenty countries who for many years have researched some of the unique sceneries on the planet. The thirty six chapters present each continent of the world. They describe landscapes of different origin, so that the reader can learn about the complexity of processes behind the sceneries. This is a useful reference book, linking geomorphology with global initiatives focused on nature conservation.

Book Description
Alluvial fans are important sedimentary environments. They trap sediment delivered from mountain source areas, and exert an important control on the delivery of sediment to downstream environments, to axial drainages and to sedimentary basins. They preserve a sensitive record of environmental change within the mountain source areas. Alluvial fan geomorphology and sedimentology reflect not only drainage basin size and geology, but change in response to tectonic, climatic and base-level controls. One of the challenges facing alluvial fan research is to resolve how these gross controls are reflected in alluvial fan dynamics and to apply the results of studies of modern fan processes and Quaternary fans to the understanding of sedimentary sequences in the rock record. This volume includes papers based on up-to-date research, and focuses on three themes: alluvial fan processes, dynamics of Quaternary alluvial fans and fan sedimentary sequences. Linking the papers is an emphasis on the controls of fan geomorphology, sedimentology and dynamics. This provides a basis for integration between geomorphological and sedimentological approaches, and an understanding how fluvial systems respond to tectonic, climatic and base-level changes.
