The vast area of swamp and wetlands of the Southern Sudan, the Sudd, absorbs and dissipates by evaporation about half the inflow from the upper catchment of the White Nile. Ways and means of reducing these losses by canalisation have been under engineering investigation since the beginning of the twentieth century, the objective being to provide additional water for irrigation and hydro-electric power in Egypt and the northern Sudan. Construction of the Jonglei Canal began in 1977; at the end of 1983 it was halted by civil war, 260 kilometre from its outfall and 100 kilometres short of completion. In the area through which it passes it will, if ever completed, have varied local effects; it will reduce the seasonally river-flooded grasslands, which are of crucial importance to the pastoral sector of the local economy and cut the line of seasonal migration of man, livestock and wildlife. Yet it will bring benefits and opportunities as well as adverse effects. Based on scientific studies of the area carried out in the early 1950s and again between 1978 and 1983, the aim of the book is to present a multi-disciplinary survey of the very complex interrelated hydrological, ecological, biological and human problems involved.

Today, the First World War is remembered chiefly for the carnage of the Western Front, but at the time the Royal Navy's blockade of Germany was a more frequent source of debate. For, even at a time of war, there were influential voices in Britain who baulked at a concept of economic warfare that hindered the free passage of goods on the high seas, and brought German society to the brink of famine. To further our understanding of these issues, this book looks at the background to the blockade, and the effects of its implementation in 1914. It argues that there was a widely shared, but largely unwritten, strategic culture within British naval circles which accepted that in a war with a major maritime power the British response would be to attack enemy trade. This is demonstrated by the fact that from at least the late 1880s the Royal Navy planned for the use of armed merchantmen to enforce an economic blockade of an enemy. This it did by entering into detailed arrangements with major British shipping companies for the design and subsidy of liners with the potential for use as merchant cruisers, and stockpiling their prospective armament. In line with the contemporary, Corbettian, view that seapower depends upon free communications, the book concludes by asserting that the primary role of the Grand Fleet in the First World War was to guarantee the ability of the merchant cruisers on the Northern Patrol to interdict German seaborne trade, rather than to engage in large set-piece battles.
