Terwijl in het noordwesten van China water schaars is, neemt de vraag ernaar snel toe vanwege bevolkingsgroei, inkomensstijging, industrialisatie en verstedelijking. Omdat neerslag ontoereikend is, speelt irrigatie een cruciale rol in de landbouw, zowel in de regio als in China als geheel. Echter, ondanks waterschaarste is irrigatie inefficiënt. Dit proefschrift analyseert vraaggeoriënteerde en beheergeoriënteerde beleidsmaatregelen om de efficiëntie van irrigatiewatergebruik te verbeteren in de Guanzhong vlakte. De effecten van de volgende beleidsinstrumenten worden geanalyseerd: hervorming van irrigatiewaterbeheer, de prijs van water, stimulering van het gebruik van waterbesparende technieken en bevordering van de bewustwording van boeren van water schaarste. De geanalyseerde gegevens zijn paneldata van 800 boeren voor de periode 2000-2005 en cross-sectie data van 460 boeren die in 2011 zijn geënquêteerd. De belangrijkste conclusies zijn de volgende. Ten eerste, hervorming van irrigatiewaterbeheer heeft een positief efficiency effect. Verenigingen van watergebruikers hebben het grootste effect, gevolgd door naamloze vennootschappen en private ondernemingen. Ten tweede heeft stimulering van het bewustzijn van waterschaarste een positief effect. Ten derde, verspreiding van informatie via sociale netwerken is een belangrijk middel om de bewustwording van waterschaarste te bevorderen. Ten vierde, zowel boeren die risico afkerig zijn als boeren die ervaring hebben met productierisico’s, zijn geneigd zich meer, en meer geavanceerde, waterbesparende technieken eigen te maken.While water is scarce in northwestern China, the demand for it is growing rapidly due to population and income growth, industrialization and urbanization. Due to insufficient precipitation, irrigation plays a crucial role in ensuring agricultural production and food security in the region and China as a whole. Despite its scarcity, irrigation water use efficiency is low because of weak water management. Hence, this thesis focuses on demand and institutional oriented strategies to improve irrigation water use efficiency. It analyzes the impacts of several policy handles, notably irrigation water management reform, water pricing, stimulation of the adoption of water-saving techniques, and enhancement of farmers’ awareness of water scarcity, on farmers’ irrigation water use efficiency.Data analyzed includes a panel data set of 800 farmers for the period 2000-2005, and a cross-sectional data set of 460 farmers collected in 2011 in the Guanzhong Plain. The main conclusions are the following. Firstly, irrigation management reform has a positive impact with water users association having the largest effect, followed by joint-stock co-operative and private company. Secondly, enhancing awareness of water scarcity is effective in increasing irrigation water efficiency and adoption of water-saving techniques. Thirdly, dissemination of information via social networks, rather than via the media, is an important vehicle to enhance awareness of water scarcity. Fourthly, risk-averse farmers who have experienced production risk are more likely to adopt more, and more advanced water-saving techniques

Water scarcity is threatening the very survival of the Chinese nation (Jiabao Wen, former Chinese prime minister cited in Chapter 1). 2. The introduction of psychological and sociological concepts in economic theory will stimulate application of Structural Equation Modelling in econometrics. (Several Chapters)  3. Water users’ associations outperform joint-stock cooperatives and private companies in improving farmers’ water use efficiency (Chapter 2). 4. Dissemination of information via social networks, rather than via the media, is an important vehicle to enhance awareness of water scarcity in the Guanzhong Plain (Chapter 3). 5. Acceptance of water pricing can be enhanced by disseminating information that income losses due to higher water prices can be offset by savings due to increased  water use efficiency (Chapter 4). 6. Perception of water scarcity improves water use efficiency, but also vice versa: efficient farmers have a more optimistic view of combating water scarcity via improved efficiency (Chapter 4). 7. In the absence of crop insurance adoption of advanced water-saving techniques is an alternative hedging instrument against droughts (Chapter 5).  8. Writing a paper is like raising a baby, it cries even it is well taken care of. 9. Time is like water in a sponge; there is always more as long as you squeeze (Lu Xun, 1881-1936). 10. The supreme art of war is to subdue the enemy without fighting (Sun Tzu, 544-496 BC) 11. Women hold up half the sky (Mao Zedong, 1893-1976). 12. He who knows all the answers has not been asked all the questions (Confucius, 551-479 BC). 13. When you see a good person, think of becoming like her or him. When you see someone not so good, reflect on your own weaknesses (Confucius, 551-479 BC). 14. Do not do evil things even though they may be insignificant. Do not give up good things even though they may be minor (Liu Bei, 161-223)． 15. Dutch discuss business in the office, Chinese at the dinner table.
