| This paper analyses the efficiency with which water is used in small-scale irrigation schemes in North-West Province in South Africa and studies its determinants. In the study area, small-scale irrigation schemes play an important role in rural development, but the increasing pressure on water resources and the approaching introduction of water charges raise the concern for more efficient water use. With the Data Envelopment Analysis (DEA) techniques used to compute farm-level technical efficiency measures and sub-vector efficiencies for water use, it was shown that under Constant Returns to Scale (CRS) and Variable Returns to Scale (VRS) specification, substantial technical inefficiencies, of 49% and 16% respectively, exist among farmers. The sub-vector... |

| As a result of the growing world population and enhanced by the rising of living standards, competition for water is growing and this causes increased pressure on water resources worldwide. This tendency gave rise to the development of the integrated water resources management approach (IWRM), acknowledging the need to manage water resources in a holistic and integrated way. The IWRM objective to optimize economic, social and environmental outcomes of water management, can however only be reached if impact of water uses is correctly assessed. Nevertheless, often multiple uses of water within sectors are insufficiently recognized in planning and management. One of these neglected uses is the productive water use by households. Nonetheless, this use is... |

| The paper aims to investigate the economies of scale of Water Users’ Associations (WUA) in Tunisia. During the last years there has been a lot of discussion in Tunisia about the optimal size of WUAs, which allows more efficient management of the water resources at the local level. In this work we propose to see if the size of the WUA in the governorate of Nabeul (Central-Eastern part of Tunisia) would have to increase or decrease in order to maximize their efficiency. Apart from this qualification we also quantify the scale efficiency and scale elasticity of the WUA using Data Envelopment Analysis (DEA) models. The results show that the output space (volume of water distributed and number of ha managed and irrigated) of the WUA that attain a high level of... |

| With increasing water scarcity, research on policy options for improved water allocation and governance becomes an urgent priority for many developing and developed countries. Evaluating institutional alternatives is however a challenging task. This article takes a comparative approach and compares case study data from Tunisia and South Africa highlighting the importance of the water rights system for irrigators. Using contingent valuation methods the benefits for water users of changes in water rights systems are quantified. In both countries WTP estimates reveal that from the farmers’ perspective significant improvements can be made to the current water rights systems. This is valuable information for policy makers to guide institutional reforms. |

| In South Africa water law has recently changed, adopting the principle of water as an economic good, thus levying charges on its use. For small-scale irrigators this is an important change, because currently their water use is entirely subsidized. In the coming years, subsidies will gradually decrease and an essential expected benefit of this policy change is that water use efficiency will rise, leading to reduced consumption and possible reallocation of the water saved. The exact impact of the water pricing policy on the irrigation water use or on the farmers' production system is however unclear. This study introduces a new methodology, based on data envelopment analysis, that allows estimating the effects on the agricultural production process and water... |
