Tropical and sub tropical West Africa Marine and continental changes during the Late Quaternary Excerpt :

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 assemblages over time periods up to and greater than 125,000 years. These are signals of temperature and circulation shifts and allow Interglacial and Glacial comparisons on a regional and inter-hemispheric scale. However, this effort to synthesize the existing knowledge cannot yet aspire to a global modelling. Linking with terrestrial records, albeit spatially patchy and generally lacking a firm chronology, this book points to shorter time scale chronologies from lakes, marshes and river deposits. Diverse and not very wellknown literature, both French and English, is reported here. Lastly, the book records recent knowledge of the first steps of human occupation of frequently hostile environments and considers the environmental impact of ancient and modern societies. * Covers the recent studies about marine Quaternary environments off West Africa, as well as continental Quaternary environments of tropical and sub-tropical West Africa (over 10,000 to 100,000 years) * Compares the parallel between palae-oenvironmental trends according to latitudinal gradients

Meteorology of Tropical West Africa Excerpt :

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 of the world’s most remarkable weather systems, making it an inspiring region for students to investigate. The weather of West Africa affects human livelihoods on a daily basis, and can contribute to hardship, poverty and mortality. Therefore, the ability to understand and predict the weather has the potential to deliver significant benefits to both society and economies. The book includes comprehensive background material alongside documentation of weather forecasting methods. Many examples taken from observations of West African weather systems are included and online case-studies are referenced widely.

Carbon Management in Tropical and Sub Tropical Terrestrial Systems Excerpt :

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 help to offset C emissions from fossil fuel combustion and other C-emitting activities, while also enhancing soil quality and long-term agronomic productivity. However, developing effective policies for creating terrestrial C sinks is a serious challenge in tropical and subtropical soils, due to the high average annual temperatures in these regions. It can be accomplished by implementing improved land management practices that add substantial amounts of biomass to soil, cause minimal soil disturbance, conserve soil and water, improve soil structure, and enhance soil fauna activity. Continuous no-till crop production is arguably the best example. These soils need technically sound and economically feasible strategies to sustainably enhance their SOC pools. Hence, this book provides comprehensive information on SOC and its management in different land-use systems, with a focus on preserving soils and their ecosystem services. The only book of its kind, it offers a valuable asset for students, researchers, policymakers and other stakeholders involved in the sustainable development and management of natural resources at the global level.

Shifting the Paradigms for Sustainable Wildmeat Use in Tropical and Sub Tropical Regions Excerpt :

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 around a rather simplistic paradigm where wildmeat use is unsustainable and should therefore be reduced or stopped to ensure wildlife conservation. Indeed, until the early start of this century most research efforts have been rooted in the biological disciplines, focused on quantifying the magnitude of the trade and measuring its level of destruction on wildlife species and ecosystems. This most often led to the institution of prohibitive policies intended for the protection of the wild resources, such as separating people from wildlife, expanding tightly-managed protected area networks, blanket criminalization of wild meat hunting, and increasing enforcement and interdiction measures. More recently, based on the elucidation of the role of wild meat in human livelihoods, some practitioners defend the idea that consumptive uses of wildlife are the only way to save it in the long run.

Tropical Marine Ecology Excerpt :

No realm on Earth elicits thoughts of paradise more than the tropics. The tropical marine realm is special in myriad ways and for many reasons from seas of higher latitude, in housing iconic habitats such as coral reefs, snow white beaches, crystal clear waters, mangrove forests, extensive and rich seagrass meadows and expansive river deltas, such as the exemplar, the Amazon. But the tropics also has an even more complex side: tropical waters give rise to cyclones, hurricanes and typhoons, and unique oceanographic phenomena including the El Niño- Southern Oscillation which affects global climate patterns. Tropical Marine Ecology documents the structure and function of tropical marine populations, communities, and ecosystems in relation to environmental factors including climate patterns and climate change, and patterns of oceanographic phenomena such as tides and currents and major oceanographic features, as well as chemical and geological drivers. The book focuses on estuarine, coastal, continental shelf and open ocean ecosystems. The first part of the book deals with the climate, physics, geology, and chemistry of the tropical marine environment. The second section focuses on the origins, diversity, biogeography, and the structure and distribution of tropical biota. The third part explores the rates and patterns of primary and secondary production, and their drivers, and the characteristics of pelagic and benthic food webs. The fourth part examines how humans are altering tropical ecosystems via unsustainable fisheries, the decline and loss of habitat and fragmentation, Further, pollution is altering an earth already in the throes of climate change. Tropical Marine Ecology is an authoritative and comprehensive introduction to tropical marine ecology for advanced undergraduate and postgraduate students. It is also a rich resource and reference work for researchers and professional managers in marine science.
