“…As Gleick et al (2011) argue, we must design appropriate wateraccounting procedures in place (both farm and basin) in order to identify the opportunities for water savings and then apply specific water conservation and efficiency practices based on a combined use of economic, technical, social and political tools to reduce pressures on scarce water supplies.…”

POST-PRINT VERSION AbstractThe hypothesis of a rebound effect as a consequence of water saving investments is taken analogically from the Jevons paradox models in energy economics. The European Commission (EC) alert about the consequences in water stressed regions that are investing heavily in modernization of irrigation networks and systems. This paper reviews the literature, linking water savings with water diversion and water depletion, both from theoretical models and empirical evidence from the published research. In order to increase knowledge of this phenomenon, a new empirical case study is presented based on a survey of 36,000 ha of recently modernized irrigated areas in the Guadalquivir basin (southern Spain). The results of the case study illustrates the conditions that may avoid rebound effect, although the results of the available empirical evidence and the published theoretical research are diverse and lead to contradictory results. Further research is therefore needed to determine the causes and solutions of water saving investment impacts and the possible speculative rebound effect.Keywords: Water conservation; Jevons paradox; Rebound effect; Water pricing; Water use; Water consumption; Spain Highlights The present study analyzes the theoretical and empirical evidence that water saving investments may lead to increased water use and/or consumption. Some authors suggest that if irrigated land expansion is not constrained, increased water abstractions are likely to occur. When land expansion is constrained and water rights are controlled, water depletion does not increase. The results of published research are diverse and have yielded contradictory results regarding the rebound effect as a consequence of water saving investments.

“…The most accurate methods of measuring ET a are lysimeters, neutron probes, and gravimetric methods. However, since the 18 demonstration sites were scattered over a large area, and since no lysimeters and neutron probes were available, the ET a was estimated using a standard soil-moisture balance equation [6,7]:…”

ABSTRACT, indicating a significant potential for improving water productivity through agronomic and irrigation management interventions. The ratio of average ET a divided by average TWA gave an average application efficiency of 78% (some fields under-irrigated and some fields over-irrigated), the remaining 22% of water applied leaving the field. Since more than 60% of the water used for irrigation in Tajikistan and Uzbekistan is pumped from, even if all this 22% of water returns to the stream, substantial energy savings would accrue from improving the average application efficiency at field level. The range of values for TWA indicates the inequity in water distribution/accessibility. Addressing this inequity would also increase water productivity at field and project level.

Water supply disruptions are prevalent in various parts of South Africa. The Lower Sundays River Valley is not an exception. However, there is currently no physical shortage of water in the catchment. This study defines institutional arrangements and dynamics in the water sector in South Africa, using the Lower Sunday River Water Users Association as the case study. Key informant interviews reveal that relevant stakeholders are not adequately represented in management committees. Such institutional arrangement vacuums can lead to a failure of the water institutions in the catchment to provide water resources effectively.
