Study of Clay Materials from Northern Cameroon: Application in the Habitat of Sahelian Areas by Touogam Touolak Benedicte Pdf

In its diversity of culture and landscape, stands the dense archipelago of plains, savannas and wooded steppes of the northern part of Cameroon. This part of Cameroon dominated by its flat landscapes, its ferralitic soil, somewhat ferruginous and very exactly clay; is subject to extremely high temperatures, since it is an integral part of the Sahel zone. The question of suitable housing for a Sudano-Sahelian climate is therefore not a new concept in this part of Cameroon. Traditional and ancestral construction techniques using the clay material sometimes associated with crushed straw, or even with cement used as a binder, still exist today. It is therefore not uncommon to find in slightly more remote localities (here assimilated to villages, districts and districts), constructions made entirely of rubble (we are referring here to the city of Mokolo and its surroundings, in the department from Mayo-Tsanaga to Far North Cameroon), and also from terracotta bricks (much more on the side of Yagoua and its surroundings, in the department of Mayo-Danay in Far North Cameroon). Still in Far North Cameroon on the Logone et Chari side, the construction of the shell houses of the Mousgoum people dominate the architectural landscape. Going up in North Cameroon on the side of Garoua in the locality of Pitoa, Djalingo, Boulgou, Tinguelin and Badebroun including all the other surrounding localities, soil morphology, architectural landscape and all other geotechnical parameters of soil characterization remain the same; the use of the material “earth” in particular the cooked and compressed brick predominates the habitats. In most cases, the soils are 90% sandy and clayey in nature; this is what the relevant results obtained from years of research tell us.

Uan Tabu in the Settlement History of the Libyan Sahara by Elena A. A. Garcea Pdf

Uan Tabu is a rockshelter on the left bank of the central valley of the Wadi Teshuinat, which is a main ancient water course in the Tadrart Acacus mountain range. It is located in the Fezzan region, south-western Libya (Great Jamahirya). The site was discovered by Fabrizio Mori in 1960 and was re-excavated and studied by a multi-disciplinary team at the beginning of the 1990s. It has also remarkable rock art that includes paintings from the Round Head and Pastoral phases. Between 1960 and 1963, a trench was dug into the archaeological deposit at the foot of the rock wall. The results of the 1960s’ excavation have never been published before, apart from some brief notes. They are thoroughly described and discussed in the present volume. Between 1990 and 1993, the excavation was resumed and extended. The 1990s’ excavation has been preliminarily published. Further information and details are now presented and commented. A stratigraphic and cultural correlation between the two excavations is also attempted in this volume. Four main archaeological and paedological units were identified and dated. They spanned from the Late Pleistocene to the Late Holocene. The earliest one, dating to the Pleistocene, included an Aterian techno-complex and was dated to around 61,000 years BP. Later, during the Early Holocene, a ‘pre-pastoral’ occupation occurred since the 10th millennium bp. This period was differentiated in two phases characterised by different socio-cultural systems: 1. during the Early Acacus (around 9800-8800 years bp), the site was used on a seasonal basis, probably during the dry season, for practising hunting activities; 2. during the Late Acacus (around 8800-8600 years bp), a more sedentary lifestyle was hypothesised for the inhabitants of the site. These two cultural facies comprised the upper three units. The fourth phase of occupation of the shelter was only attested to the surface of the site, but it could be still considered as an indication of the use of the site during the Late Holocene, as late as the 4th millennium bp. A dung fill in the wall of the rockshelter dated to the end of this, Late Pastoral, phase and is the only evidence for domesticated animals.

The Dry Forests and Woodlands of Africa by Emmanuel N. Chidumayo,Davison J. Gumbo Pdf

The dry forests and woodlands of Sub-Saharan Africa are major ecosystems, with a broad range of strong economic and cultural incentives for keeping them intact. However, few people are aware of their importance, compared to tropical rainforests, despite them being home to more than half of the continent's population. This unique book brings together scientific knowledge on this topic from East, West, and Southern Africa and describes the relationships between forests, woodlands, people and their livelihoods. Dry forest is defined as vegetation dominated by woody plants, primarily trees, the canopy of which covers more than 10 per cent of the ground surface, occurring in climates with a dry season of three months or more. This broad definition - wider than those used by many authors - incorporates vegetation types commonly termed woodland, shrubland, thicket, savanna, wooded grassland, as well as dry forest in its strict sense. The book provides a comparative analysis of management experiences from the different geographic regions, emphasizing the need to balance the utilization of dry forests and woodland products between current and future human needs. Further, the book explores the techniques and strategies that can be deployed to improve the management of African dry forests and woodlands for the benefit of all, but more importantly, the communities that live off these vegetation formations. Thus, the book lays a foundation for improving the management of dry forests and woodlands for the wide range of products and services they provide.

Managing Socio-ecological Production Landscapes and Seascapes for Sustainable Communities in Asia by Osamu Saito,Suneetha M Subramanian,Shizuka Hashimoto,Kazuhiko Takeuchi Pdf

This open access book presents up-to-date analyses of community-based approaches to sustainable resource management of SEPLS (socio-ecological production landscapes and seascapes) in areas where a harmonious relationship between the natural environment and the people who inhabit it is essential to ensure community and environmental well-being as well as to build resilience in the ecosystems that support this well-being. Understanding SEPLS and the forces of change that can weaken their resilience requires the integration of knowledge across a wide range of academic disciplines as well as from indigenous knowledge and experience. Moreover, given the wide variation in the socio-ecological makeup of SEPLS around the globe, as well as in their political and economic contexts, individual communities will be at the forefront of developing the measures appropriate for their unique circumstances. This in turn requires robust communication systems and broad participatory approaches. Sustainability science (SuS) research is highly integrated, participatory and solutions driven, and as such is well suited to the study of SEPLS. Through case studies, literature reviews and SuS analyses, the book explores various approaches to stakeholder participation, policy development and appropriate action for the future of SEPLS. It provides communities, researchers and decision-makers at various levels with new tools and strategies for exploring scenarios and creating future visions for sustainable societies.

Soils, Ecosystem Processes, and Agricultural Development by Shinya Funakawa Pdf

The main objective of this book is to integrate environmental knowledge observed in local agriculture, based on the understanding of soils science and ecology, and to propose possible technical solutions and a more integrated approach to tropical agriculture. The chapters describe and analyze the ecological and technical countermeasures available for mitigating environmental degradation due to the increasing agricultural activities by humans, based on our scientific understanding of traditional agriculture in the tropics. This is an effective approach, as such ecological and technical tools previously involved in traditional activities are expected to be easily incorporated into present agricultural systems. The book starts with a rather classical pedological issue and analyzed traditional agricultural practices with different resource management strategies in terms of their modification of natural biological processes. It focuses on the present situation of tropical agriculture; that is, resource utilization in modern agriculture after application of technical innovation (increased application of chemical fertilizers as well as agricultural chemicals). Here, possible technical approaches to resource management that reasonably support agricultural production whilst mitigating environmental degradation are discussed. The negative impacts of agricultural development on our environment are rapidly growing, yet we are increasingly dependent on the agricultural sector for food and energy. The situation is similar in the tropics, where subsistence agriculture with low input management has long comprised most agricultural systems. Comparison of ecological and/or agronomical studies between different continents are still rare; therefore, this analysis may help clarify what is an essential problem when considering technical transportation beyond continents and/or between temperate and tropical regions.
