West Africa and the eastern Atlantic stretching from Mauritania in the north to Namibia in the south offer a large latitudinal stretch incorporating nearly symmetrical climatic gradients from the Equator. On the time scale of Quaternary Glacial and Interglacial cycles, today, we possess well-documented and recently published marine sedimentary records showing changes in oceanic and atmospheric circulations and terrestrial fluxes. Deep-sea sediment records contain a wide range of palaeoenvironmental indicators like oxygen and carbon isotopes, alkenones, foraminiferal and other planktonic

Meteorology of tropical West Africa: the Forecasters’ Handbook presents the science and practice of weather forecasting for an important region of the tropics. Connecting basic theory with forecasting practice, the book provides a unique training volume for operational weather forecasters, and is also suitable for students of tropical meteorology. The West African region contains a number of archetypal climatic zones, meaning that the science of its weather and climate applies to many other tropical regions. West Africa also exhibits some

Soil organic carbon (SOC), a key component of the global carbon (C) pool, plays an important role in C cycling, regulating climate, water supplies and biodiversity, and therefore in providing the ecosystem services that are essential to human well-being. Most agricultural soils in temperate regions have now lost as much as 60% of their SOC, and as much as 75% in tropical regions, due to conversion from natural ecosystems to agricultural uses and mainly due to continuous soil degradation. Sequestering C can

Originally published in 1987, this book brings together information previously buried in specialist sources and makes it available to the student in a non-technical and well-illustrated synthesis. It builds a clear and detailed picture of the climates of West Africa, describing and explaining them and showing how crucial this understanding is to everyday life. The climate’s relevance to water resources, agriculture, health and industry is systematically considered.

In Tropical and sub-tropical Range States, wildmeat is an important source of nutrition and income, but current extraction levels of vulnerable taxa are considered unsustainable. As such, wildmeat use is often seen as problematic for wildlife conservation. From a development perspective, balancing the nutritional needs of people who depend on wildmeat with biodiversity conservation is the greatest challenge. But why can’t wildmeat use be seen as an ally for conservation? Most analysis of wildmeat use have framed the problem

The use of exploration geochemistry has increased enormously in the last decade. The present volume specifically addresses those geochemical exploration practices appropriate for tropical, sub-tropical and adjacent areas – in environments ranging from rainforest to desert. Practical recommendations are made for the optimization of sampling, and analytical and interpretational procedures for exploration according to the particular nature of tropically weathered terrains. The underlying theme is the recognition that regions between 35°N and 35°S in particular have a common history of deep

The oceans cover 70% of the Earth’s surface, and are critical components of Earth’s climate system. This new edition of Encyclopedia of Ocean Sciences summarizes the breadth of knowledge about them, providing revised, up to date entries as well coverage of new topics in the field. New and expanded sections include microbial ecology, high latitude systems and the cryosphere, climate and climate change, hydrothermal and cold seep systems. The structure of the work provides a modern presentation of the

Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 52. The principal aim of this symposium was to describe the contributions which are made by each of the disciplines represented in the IUGG to the study of climate change. In order to present a balanced program, the Symposium was composed of invited reviews but other viewpoints were put forward during general discussion. The themes covered reflect the interests of the seven IUGG Associations and include volcanism;
