| It is indeed a privilege and an honour to deliver the FR Tomlinson Commemorative lecture this year. Although the invitation was quite unexpected, it is of course highly appreciated. When Prof Johann Kirsten phoned me with the request, I was initially not sure what topic I should address. The topic, which I have now formulated, is one which has fascinated me and certainly kept me busy for the most part of my career. I want to share with you some thoughts and perspectives, but will steer away from a laborious review or an abstract analysis. In doing so, I trust that this is appropriate within the spirit of the occasion, which is now a well established tradition in the Agricultural Economics Association of South Africa (AEASA). Let me start with a quotation... |

| The South African Water Research Commission (WRC) initiated a number of research projects aimed at determining the value of water in different sectors of the economy and in different parts of the country. This research is reviewed. Water values were found to differ significantly between sectors, between geographic areas and within geographic areas. As agriculture is a large consumer of water several studies along different rivers were undertaken, including studies on water quality. Average ratios indicate that agriculture is an inefficient user of water in terms of gross income generated per unit of water and also in terms of jobs created per unit of water. Irrigation farming is, however, an important employer of labour while it contributes 30% to the... |

| Increasing scarcity and competition for water resources has led to international recognition that public policies must change to manage water as an economic commodity. An analysis of natural resources and markets shows that limited potential exists in a regional context for trade in 'virtual water' through food imports. Policy options for intra- and intersectoral water reallocation must therefore receive priority attention. Based on experiences in other countries, emphasis is placed on successful innovations of markets in tradable water rights, local management, user-based performance assessment and water saving technologies in irrigated agriculture. The recently published National Water Policy for South Africa and draft National Water Bill that has been... |

| Transfers of water in the Crocodile River above and below the gorge (near Nelspruit and Malelane) were studied based on a survey in the area during November 2003, followed up by telephonic interviewing during March 2004. Almost all the water trades (permanent and rentals) observed in this study were from farmers above the gorge to farmers below the gorge. In order to study whether the water market promotes efficiency the data were subjected to several statistical analyses (Principal Components, Ridge Regression, Logit). It is concluded that in the transfer of water some attributes in the purchasing area such as lower production risk (sugar cane) and lower financial risk and better cash flow (bananas and sugar cane) were more important than the income per... |

| Irrigation farmers in the Lower Orange River were surveyed during October 2003 in order to study whether water marketing has promoted efficiency and to identify factors that affect future investment in irrigation farming. Econometric procedures (principal component and logit model) indicate that purchasers of water rights produce lucrative export grapes and horticultural crops with relatively less raisin, wine or juice grapes and less field crops; are more specialised in production; have more livestock (probably liquidity factor) and have a less negative view of the five-year review period. The water market has facilitated a transfer of water use from relatively lower value crops to relatively higher value crops, and also promoted the use of more advanced... |
