Mobile Technologies in the Ancient Sahara and Beyond


Book Description

"This volume is the fourth and final volume resulting from a focused programme of research and intensive group discussion of a wide range of topics related to the archaeological (and to a lesser extent, historical and anthropological/ethnographic) analysis of ancient societies in and around the Sahara, from the first millennium BC to the mid-second millennium AD. While the focus of the present volume is technology, there will inevitably be discussion of cross-overs and contrasts with the main conclusions from earlier volumes in the series. As explained in the Preface above, the Trans-SAHARA project evolved out of a long-term programme of fieldwork on an ancient people of the Libyan Sahara. Just as they occupied a significant nodal location in the Sahara, the Garamantes are at the centre of this volume, but the scope of debate here extends way beyond the history of a single group. Connections and barriers within the Trans-Saharan region (and the interrelationship between these two aspects) form one focus. In this introduction we present an overview of crucial themes and considerations which cross-cut all or many of the contributions."--




Lost Crops of Africa


Book Description

This report is the second in a series of three evaluating underexploited African plant resources that could help broaden and secure Africa's food supply. The volume describes the characteristics of 18 little-known indigenous African vegetables (including tubers and legumes) that have potential as food- and cash-crops but are typically overlooked by scientists and policymakers and in the world at large. The book assesses the potential of each vegetable to help overcome malnutrition, boost food security, foster rural development, and create sustainable landcare in Africa. Each species is described in a separate chapter, based on information gathered from and verified by a pool of experts throughout the world. Volume I describes African grains and Volume III African fruits.




Urbanisation and State Formation in the Ancient Sahara and Beyond


Book Description

This ground-breaking volume pushes back conventional dating of the earliest sedentarisation, urbanisation and state formation in the Sahara.




Sowing Seeds in the Desert


Book Description

Argues that the Earth's deteriorating condition is man-made and outlines a way for the process to be reversed by rehabilitating the deserts using natural farming.




Slavery, Agriculture, and Malaria in the Arabian Peninsula


Book Description

In Slavery, Agriculture, and Malaria in the Arabian Peninsula, Benjamin Reilly illuminates a previously unstudied phenomenon: the large-scale employment of people of African ancestry as slaves in agricultural oases within the Arabian Peninsula. The key to understanding this unusual system, Reilly argues, is the prevalence of malaria within Arabian Peninsula oases and drainage basins, which rendered agricultural lands in Arabia extremely unhealthy for people without genetic or acquired resistance to malarial fevers. In this way, Arabian slave agriculture had unexpected similarities to slavery as practiced in the Caribbean and Brazil. This book synthesizes for the first time a body of historical and ethnographic data about slave-based agriculture in the Arabian Peninsula. Reilly uses an innovative methodology to analyze the limited historical record and a multidisciplinary approach to complicate our understandings of the nature of work in an area that is popularly thought of solely as desert. This work makes significant contributions both to the global literature on slavery and to the environmental history of the Middle East—an area that has thus far received little attention from scholars.




Farming Systems in the Tropics


Book Description

Some general charscteristics of farming in a tropical environment; Shifting cultivation systems; Fallow systems; Ley systems; Systems with permanent upland cultivation; Systems with arable irrigation farming; Systems with perennial crops; Grazing systems; General tendences in the development of tropical farm systems.




Trade in the Ancient Sahara and Beyond


Book Description

Saharan trade has been much debated in modern times, but the main focus of interest remains the medieval and early modern periods, for which more abundant written sources survive. The pre-Islamic origins of Trans-Saharan trade have been hotly contested over the years, mainly due to a lack of evidence. Many of the key commodities of trade are largely invisible archaeologically, being either of high value like gold and ivory, or organic like slaves and textiles or consumable commodities like salt. However, new research on the Libyan people known as the Garamantes and on their trading partners in the Sudan and Mediterranean Africa requires us to revise our views substantially. In this volume experts re-assess the evidence for a range of goods, including beads, textiles, metalwork and glass, and use it to paint a much more dynamic picture, demonstrating that the pre-Islamic Sahara was a more connected region than previously thought.




Agriculture in Semi-Arid Environments


Book Description

The semi-arid zones of the world are fragile ecosystems which are being sub stantially modified by the activities of mankind. Increasing human populations have resulted in greater demands on semi-arid zones for providing human susten ance and the possibility that this may enhance desertification is a grave concern. These zones are harsh habitats for humans. The famines that resulted from drought during the late 1960's and the 1970's in the African Sahel illustrated the unreliability of present agricultural systems in this zone. Large fluctuations in ag ricultural production have occurred in semi-arid zones of Australia, North Ameri ca, and the Soviet Union due to periodic droughts, even though considerable ag ricultural technology has been devoted to agricultural development in these zones. The challenge to mankind is to manage these different semi-arid zones so that pro ductivity is increased and stabilized, and environmental deterioration is decreased. Irrigation can be used to increase and stabilize agricultural production in semi-arid zones as discussed in Volume 5 of this series, Arid Zone Irrigation. The present volume, Agriculture in Semi-Arid Environments, focuses on dryland farming in semi-arid zones, and is relevant to the large areas of the world where rainfall is limiting and where water is not available for irrigation. This volume is designed to assist agricultural development in these areas and consists of reviews and analyses of available information by scientists working in Africa, Australia, and at the U ni versity of California.




Principles of Agricultural Economics


Book Description

This book showcases the power of economic principles to explain and predict issues and current events in the food, agricultural, agribusiness, international trade, natural resources and other sectors. The result is an agricultural economics textbook that provides students and instructors with a clear, up-to-date, and straightforward approach to learning how a market-based economy functions, and how to use simple economic principles for improved decision making. While the primary focus of the book is on microeconomic aspects, agricultural economics has expanded over recent decades to include issues of macroeconomics, international trade, agribusiness, environmental economics, natural resources, and international development. Hence, these topics are also provided with significant coverage.




Elixir


Book Description

A history of the role of water in shaping civilization covers the aqueducts of ancient Greece, the centuries-long efforts to tame rivers in China, the Industrial Revolution, and present-day efforts to solve sustainability problems.
