Abstract. The utilization of groundwater for irrigation purposes becomes problematic if groundwater recharge decreases through climate variability. Nevertheless, the degree of groundwater utilization for irrigation increases significantly in dry periods, when the amount of green water is strongly limited. With an increasing gap between water demand and supply, new water management activities are started, which are mostly directed to increase the supply, often by overuse of local resources. In many cases such local activities results in their summarization in side-effects, which worsen the hydrological conditions throughout a region. Step by step the spatial scale of water management measures has to be extended in such cases by implementation of water transfer systems. In this contribution this general scale problem of water management is discussed at the example of an agricultural region in the Province of Shandong (P.R. of China). The local irrigation systems and the options to increase the water supply at the local scale (e.g. by waste water reuse) are discussed as well as regional measures e.g. reservoirs or barrages in rivers to increase the groundwater recharge. For this purpose, several socio-economic and hydrological models were combined. It is shown how a change of water policy towards a demand management requires a new approach to spatial aspects. Here the question arises, how hydrological most effective measures can be allocated within a region. In the case study, a reduction of agricultural irrigation and a change of the crop structure would be essential to improve the groundwater conditions, which are impaired by ongoing sea-water intrusions. A model hierarchy, which is needed to answer such problems not only from the hydrological point of view, but also considering their socio-economic feasibility, are presented.

Historical surface irrigation of pastures in the Dutch province of Noord-Brabant: visible traces of a failed experiment In the second half of the 19th century, some major changes occurred in the water management of the eastern and southern provinces of the Netherlands. Unlike the low-lying western parts of the Netherlands which were characterised by polders and had a long history of formal water boards, the higher eastern and southern parts of the Netherlands were characterized by brook systems and sandy soils, and had no centralised water boards until 1850. From the 1850s onward, water boards were introduced in these higher regions as well, and agronomical scientists and organisations like the Nederlandse Heidemaatschappij endeavoured for the modernisation of agricultural water management. One of their priorities was the introduction of modern forms of surface irrigation of pastures, in order to increase crop yields. In various places modern irrigation systems were constructed. From the 1900s onward, these systems were abandoned due to the introduction of new chemical fertilizers, among others. This article describes the construction and abandonment of one of these modern irrigation systems that was located in Liempde, in the province of Noord-Brabant. The local farmers were not interested in the new technique, and within a few years the system was transformed in a poplar plantation. Nowadays, the area is part of a nature reserve. Nonetheless, the global layout of the irrigation system is still visible.

Impact Of Urbanization

This paper summarizes the various dimensions and impacts of urbanization on Pakistan’s water resources in order to provide foundations for future water policy that will lead towards country’s socio-economic development. Urbanization is considered as a major trend of 21st century in many developing countries. Along with urbanization, increase in population growth in recent years has put a pressure on the world’s water resources in terms of water demand and pollution. Various issues related to water sector in urban areas of Pakistan have been identified including contamination of surface and ground water resources through industrial, agricultural and domestic discharge of waste and waste water, increasing floods, loss of wetlands and aquatic biodiversity, sea water intrusion and subsidence, physical reduction in water resources quantity and quality and operational and managerial incapacities. There are some other issues like unequal water distribution which together with population burden, rapid urbanization and growing industrialization are posing a huge challenge for Pakistan’s water management in 21st century. Taken together all the studies, this review suggests that to reduce vulnerability to water resources of Pakistan, there is a need for new systems of urban planning and governance institutions as the core of Pakistan’s water crisis is water management.

Water governance and management are important challenges for the River Indus Basin in Pakistan. Water governance refers to social, political and economic factors that influence water management. The water scarcity and water security are a major concern for the state to control its water resources. The study aims to give Sindh water policy by exploring the challenges to Indus Basin in managing water resources and to identify opportunities Indus Basin can look to improve water management. Interviews were conducted from water experts and analysts having 5 years’ experience or more in the water sector of Pakistan through a semi-structured self-developed questionnaire using purposive sampling technique and transcripts were analyzed using thematic content analysis. The findings show that increasing population, climatic change and rising demand of water are major challenges Indus is facing and Indus with time is getting water-scarce therefore need strong institutions, civil society and legislatures to ensure equitable distribution of water and maintain the ecosystem. The study emphasizes that water governance and management are necessary for sustainable use of water. Pakistan, the water stress country needs to address ‘governance’ at a wider scale to solve problems in the Indus Basin for the livelihood of people. The research will benefit the state, water experts, institutions as well as civil society to promote efficient use of water in Indus Basin.

If we look at the existing irrigation methods used today in the country, then they are divided into: ground, rainfall, underground or underground, drip and spray. Basically, they are transferred to the irrigation field in two forms: through gravity and pressure irrigation systems. Naturally, a gravity irrigation system is economically more expensive than a low pressure irrigation system. However, from a performance appraisal stand point, pressure irrigation methods are less efficient and have serious disadvantages

In the lower reaches of the Amu Darya, artificial irrigation was created on the basis of flood water management of the river. The first channels were wide and shallow. Saka was used for flood water management. Saka was invented by tazabagyabinces. Thechannels which derived from the Akchadarya Delta were strongly branched, and the main channels were derived from the Sarikamysh Delta

Abstract The main objective of this research paper is to assess the extent to which the concept of water accounting has been applied for water management at the river basin scale in India. For this, the study first assesses the importance given to the use of water accounting for water management in India's national water policy. It then analyses the evolution of water accounting approaches in India through a systematic review of the past research studies on the theme. Further, it looks at their contribution to decision-making concerning allocation of water resources and resolving conflicts over water sharing. Finally, it identifies the existing gaps in the methodologies for water accounting so far used in India.
