Book Description
Parched landscapes, biodiversity loss, encroaching deserts and deforestation are some of the environmental crises taking place in tropical savannas and dry forests throughout the world. To date, much research into these regions has treated humans as 'outside' or as an 'impact' only. However, over and over again, examples show that, in fact, humans are not external factors, but integral components of these systems. Humans are key determinants of savannas and dry forests, affecting patterns and processes, as well as impacts on natural resources. Unless we understand the human-environment relationship in these regions, we will never truly identify the causes or be able to provide solutions. This book therefore focuses on the roles of the past, present and future human perceptions and actions on savannas and dry forests. It examines how the views of local farmers, NGO workers, government officials and international scientists differ on the links between the social and ecological components of savannas. It deals with these multiple perspectives by using systems diagramming and conceptual modelling to provide a clearer and more explicit understanding and to promote better communication between the various actors concerned.

Book Description
Savannas are the most widespread ecosystem in the tropics and as such are subjected to great human pressure that may result in massive soil degradation. The book addresses the role of species in the function of savanna ecosystems. It is shown that savannas are enormously diverse and that four factors determine the function of savanna ecosystems: Plant Available Moisture; Plant Available Nutrients; Fire; Herbivores.

Book Description
Sustainable development is now intricately linked not just to economic growth, but more importantly, to the quality of life of people in terms of their social status, political participation, cultural freedom, environmental justice and inclusive development. For previously colonized nations like Nigeria, these linkages are believed to have been influenced by the legacies of colonial rule, positively or otherwise. Through the Gender Lens: A Century of Social and Political Development in Nigeria looks at how colonialism has enabled or hindered the roles of the state in promoting inclusive development in general, and gender equality, in particular, in the process of nation building. In this edited volume, scholars analyze a host of policies, strategies and programs, as well as empirical evidence, to expose how types of governance — from direct colonial rule in the country from 1914, through her independence in 1960, a Republic in 1963, and to different post-independence governance periods — have influenced gender relations, and the impacts of these on Nigerian women. Diverse sectoral perspectives from education, health, culture, environment, and especially politics, are presented to explain the level of attainment (or otherwise) of gender equality and the implications for Nigeria’s road to sustainable development. The emphasis on the role of the state in development particularly indicts the social and political domains of governance. Hence, the main focus of inquiry in the volume. In its twelve chapters, the authors analyze available data and other information to draw relevant conclusions, identify lessons of experience, including from some cross-country comparisons, and make concrete recommendations for more gender-inclusive systems of governance in the next century of Nigeria’s nationhood.

Book Description
This study reviews how West African deforestation is represented and the evidence which informs deforestation orthodoxy. On a country by country basis (covering Sierra Leone, Liberia, Cote D'Ivoire, Ghana, Togo and Benin), and using historical and social anthropological evidence the authors evaluate this orthodox critically. Reframing Deforestation suggests that the scale of deforestation wrought by West African farmers during the twentieth century has been vastly exaggerated. The authors argue that global analyses have unfairly stigmatised West Africa and obscured its more sustainable, even landscape-enriching practices. Stessing that dominant policy approaches in forestry and conservation require major rethinking worldwide, Reframing Deforestation illustrates that more realistic assessments of forest cover change, and more respectful attention to local knowledge and practices, are necessary bases for effective and appropriate environmental policies.

Book Description
The rain forests of West Africa have been designated as one of the world's hotspots of biodiversity. They extend from Ghana to Senegal and are referred to as the Upper Guinean forests. Because of their isolated position, they harbour a large number of rare and endemic animal and plant species.This book focuses on the biodiversity and ecology of these forests. It analyses the factors that give rise to biodiversity and structure tropical plant communities. It also includes an atlas with ecological profiles of rare plant species and large timber species.

Book Description
These papers derive from a workshop on "Quaternary Sedimentary Records in Central Africa and their Palaeoenvironmental Interpretation", held at the 15th INQUA Congress. They mainly cover the Late Quaternary to Holocene climate and environmental history of today's rainforest regions.
