The purpose of this paper is to describe a web-based system to assist on-farm design and management of surface irrigation systems. This application was designed to be an appropriate tool for generating design alternatives associated with attributes of technical, economic, and environmental nature, and handling and evaluating a large number of input and output data. It also allows the evaluation and ranking of design alternatives using multicriteria analysis where criteria are weighted according ...

To cope with water scarcity in agriculture, water saving is a major priority, by upgrading the irrigation techniques and practices. Hetao Irrigation District, Inner Mongolia, China, a large area located in the water scarce upper Yellow River basin, is an example of this problem. This process requires information and communication technologies to bring knowledge to field technicians and farmers, favoring this development. On this context, the Web-based services are particularly effective in contr...

The sustainability of the Hetao Irrigation System, located in the water scarce upper Yellow River basin, is a priority considering the need for water saving, increased water productivity, and higher farmers’ incomes. The upgrading of basin irrigation, the main irrigation method, is essential and includes the adoption of precise land levelling, cut-off management, improved water distribution uniformity, and adequate irrigation scheduling. With this objective, the current study focuses on upgradin...

Water resources management in the Yellow River basin, China, is facing a paradigmatic change in consequence of an unbalanced supply and demand due to an increased demand for water from non-agricultural sectors and a reduced supply due to climate change that reduced precipitation and increased climatic demand. The problem is aggravated by low equity of spatial water allocation in the basin. A supply reduction in the upstream basin area aims to control the water scarcity conditions occurring in th...

Intercropping is commonly used in the Hetao irrigation district, upper Yellow River basin, where the main crops are wheat, maize and sunflower. For a better use of land, water, radiation energy, and nutrients, spring wheat is traditionally intercropped with maize (W–M) and, more recently, with sunflower (W–S). Considering the need to reduce diversions of water for irrigation in Hetao, this study aims to assess crop water use of W–M and W–S intercropping systems in comparison to the same crops in...

Water-saving irrigation needs to be implemented in Hetao irrigation district to help satisfying the demand by other users in the Yellow River basin. Aiming at assessing the potential irrigation performance and water saving at farm level, a set of traditional basins and another of precision-levelled basins cropped with maize, wheat and sunflower and managed by farmers were evaluated. Data were collected to characterise the basin sizes, microtopography, inflow rates, advance and recession times, c...
