Propagation of Drought: From Meteorological Drought to Agricultural and Hydrological Drought

Drought is a hazard that occurs everywhere in the world (both in dry and in wet areas). Despite the controversy regarding drought changes in the last decades [1–3], increases in drought intensity are clearly identified in some areas [4] and it is believed that although increased heating from global warming may not directly cause droughts, it is expected that when droughts occur, they are likely to set in quicker and be more intense [5]. Throughout its history, China has frequently suffered from drought disasters due to its monsoon climate and was regularly hit hard by droughts over the last decades. Although little evidence of an expansion of the area affected by droughts was found in China over the last 50 years [6], severe droughts in southwestern China in 2010 and the middle/lower Yangtze Basin and Huaihe River Basin in 2011 have drawn more attention from the research community as well as from the public and governments alike on the impacts and problems brought on by drought. Poor performance by China’s emergency response management during recent major drought events highlights the necessity of improving both drought preparedness and emergency response skills

Controlling the farmer: colonial and post- colonial irrigation interventions in Africa

Aiming at full control over farmer actions was a shared characteristic of colonial irrigation engineering approaches. However, the way control was sought in African irrigation projects was different from Asian colonies. This paper traces the origins of colonial approaches to irrigation development in Africa and the continuities between colonial and post-colonial approaches. The Kano River Project in Nigeria, part of a larger irrigation development program from the late 1960s and early 1970s, serves as a typical example of a post-colonial irrigation system in which engineers drew upon colonial experiences. The Dutch engineers responsible for developing the system applied technologies from the Netherlands East Indies to regulate water flows in the system. At the same time, they engaged in a debate on how to organize farmers in the project to ensure efficient and rational use of water in irrigated farming. They joined project managers in viewing strong control over farmer production – a central feature of African colonial irrigation projects – as key to success. However, given the social conditions in the Kano area, particularly landownership, this strong control proved difficult to realize

Aspects of irrigation development in the Netherlands East Indies

The ‘Romijn’ discharge measurement structure was developed in the Netherlands East Indies. By the end of the colonial period in the 1930s, it had become the standard structure in irrigation. The Romijn design is not only still the main discharge measurement structure in Indonesia, it is also used in Dutch water management practice and education. The question of continuity is at the heart of concepts such as ‘technological tradition’ or ‘technological regime’, and this continuity links the information embodied in a community of practitioners with the hardware and software the members master. Such communities define accepted modes of technical operation. Engineering education is an important mechanism in preference-guided selection of design solutions, and obtaining an engineering degree is much like passing the preparatory requirements for community membership. When, in 1967, a civil engineering student from Delft Polytechnic presented his final paper for an irrigation design to his supervisors, the first question they asked was why he had not used a Romijn weir as an off-take structure. The Dutch irrigation regime, which consists of the explicit and implicit rules of Dutch irrigation design, is the central subject of this paper. In this paper I shall discuss two related issues: (1) how the Netherlands East Indies irrigation regime developed, and (2) how the (dis)continuities in irrigation education and practice following Indonesian independence can be understood. Naturally, while discussion of these issues, to a certain extent at least, depends on the data available, it also depends on the researcher’s perspective
