  • BBA Pumps irrigation pumps, an unseen hero of daily life

    The Netherlands receives on average 800 mm of rain each year. This, you may feel is the reason why you relatively never see BBA irrigation pumps out in the field. But it is more likely due to the fact that the B series of irrigation pumps rarely sits idle. Due to their convenient mounting on a wheelbarrow frame they can be easily returned back to the barn as soon as the job is done. ...

  • Irrigation water requirements for seed corn and coffee under potential climate change scenarios

    The impact of potential future climate change scenarios on the irrigation water requirements (IRRs) of two major agricultural crops (coffee and seed corn) in Hawai'i was studied using the Irrigation Management System (IManSys) model. In addition to IRRs calculations, IManSys calculates runoff, deep percolation, canopy interception, and effective rainfall based on plant growth parameters, site ...

  • Watermills in the historic irrigation system ‘Palmeral de Elche’, Spain: an example of early hydropower exploitation

    With more than 180,000 date palms, the Palmeral de Elche is the largest palm grove in Europe. In 2000, United Nations Educational, Scientific and Cultural Organization (UNESCO) declared a part of it a World Heritage Site. Actually, the Palmeral is a historic irrigation system with rows of palm trees flanking rectangular fields and serving as a windbreak and shade for the cultivation of wheat, ...

  • Reflections on evolving water management institutions and institutional bricolage: a case of irrigation schemes in Iringa Rural and Kilombero districts, Tanzania

    Over the past 40+ years, evolution of water institutions responsible for allocation and distribution of water has been enormous. This paper analyzes the evolution of both formal and informal water management institutions and how they affect today's processes of allocating and distributing water in farmer-managed irrigation schemes (FMISs). It also assesses how farmers translate and modify ...

  • Colorado Irrigation Canal Channels - Case Study

    Project Background “Different materials to protect canal liners had been tried in irrigation canals across the West over the past 15 or 20 years.   One typical method uses a low cost earthen material like clay. Over time, however, these systems begin to crack and start to leak.  It’s not a very efficient way to convey water,” notes Joe Kaul, Kaul ...

  • Designing a rainwater harvesting system for urban green roof irrigation

    Green roof systems have been suggested to ease the growing urban environmental problems resulting from rapid urbanization. However, the irrigation of green roofs heavily depends on using precious potable water and consequently generates negative environmental effects. Rainwater has been recommended to address this dilemma, but the design method has not been well developed. In this study, the ...

  • Prospects of desalination for irrigation water in the Sultanate of Oman

    The most limiting factor for the agricultural sector in the Sultanate of Oman is a lack of water, and security of supply in terms of both quantity and quality. Salinization of both soils and groundwater systems along the coastal strip of Al-Batinah has placed a substantial burden on farmers regarding crop selection and, therefore, farm profitability. Desalination of brackish and seawaters ...

  • Reuse of constructed wetland effluents for irrigation of energy crops

    The aim of this study was to evaluate biomass production of promising ‘no-food’ energy crops, Vetiveria zizanoides (L.) Nash, Miscanthus × giganteus Greef et Deu. and Arundo donax (L.), irrigated with low quality water at different evapotranspiration restitutions. Two horizontal subsurface flow (H-SSF) constructed ...

  • Irrigation challenges in the sub-humid US Mid-South

    Irrigated area in the Mid-South USA continues to increase and now totals four million ha. Because of low available water holding capacities and shallow root-limiting layers in many soils, irrigation management is difficult. Water quality and water use efficiency impacts under irrigation are poorly understood, but comprehension is necessary if conversion from groundwater to surface water supplies ...

  • A policy option for valuing irrigation water in the dry areas

    Participants at the international conference on policies for water and food security in the dry areas, held in June 2013, agreed that, given the fast pace of depletion of groundwater, the issue of water valuation in the dry areas is no longer one of whether or not, but rather of how. Policies that have been or are perceived to have adverse effects on the cost of agricultural production or food ...

  • Assessing potential of water rights and energy pricing in making groundwater use for irrigation sustainable in India

    Groundwater emerged as a major source of irrigation in India during the mid-1970s. However, a large expansion in well irrigation due to a massive rural electrification programme, government policies of promoting private tube well construction and large subsidies on electricity for agricultural use resulted in groundwater over-abstraction in many semi-arid and arid regions of India. In addition, ...

  • Wastewater reuse for irrigation and seawater intrusion: evaluation of salinity effects on soils in Cyprus

    Climate change and the continuous population growth increase the demand for water, which in arid and semiarid regions, like the Mediterranean, is considered a limited resource. Future demands will not be met by traditional water resources like surface and groundwater. In order to handle increased water demand, the treated wastewater originating from municipal wastewater treatment plants is ...

  • Solar DC Submersible Pumps as an alternate source for irrigation in India

    IN the state of Andhra Pradesh, India, about 62.8 lakh (6.2 million) hectaresa yield fruits, vegetables, turmeric, chilies and regular crops. About 53% of this land is irrigated by wells and borewells. This segment applies to farms or orchids owners having borewells of 5 hp (3.75 kW) and above. In areas where there is no grid supply, farmers are compelled to use diesel pump sets to irrigate the ...

  • Wolf, bird and bread!

    Eyüp Yüksel was relaxing in Ankara on a warm autumn day in 2000, drinking tea from a traditional glass cup, when he heard the news that Tuz Gölü — Lake Tuz or Salt Lake — had been declared a protected area. As one of the staff of the Turkish Environmental Protection Agency for Special Areas (EPASA) he had been waiting and hoping for this decision but he was still ...

  • How does participatory irrigation management work? A study of selected water users' associations in Anand district of Gujarat, western India

    Measuring the performance of water users' associations (WUAs) is a complex task. Literature associates a large number of parameters with their success and failure. This paper presents an in-depth study of two WUAs that are considered to be functioning well by the irrigation department in Anand, India. It discusses some new issues and innovations being tried out in Anand, namely: (1) ...

  • India's groundwater irrigation boom: can it be sustained?

    Development of groundwater irrigation (GWI) has been very impressive in India, especially after the introduction of the green revolution. The area under GWI accounts for 62% of the net irrigated area today. Though GWI provides added benefits to farmers, compared to other sources of irrigation, the continuous exploitation of groundwater of late has resulted in a drastic drop in the water table, ...

  • Analysis of constructed wetland performance for irrigation reuse

    Most of the wastewater treatment systems in small rural communities of the Cova da Beira region (Portugal) consist of constructed wetlands (CW) with horizontal subsurface flow (HSSF). It is believed that those systems allow the compliance of discharge standards as well as the production of final effluents with suitability for reuse. Results obtained in a nine-month campaign in an HSSF bed pointed ...
