  • Cost Effective Irrigation with Centre Pivot Irrigation Systems

    There are certain factors that should be taken into consideration when choosing the best irrigation system for your specific requirements. Some of these factors include the type of crop you are watering, the size of the land which requires irrigation, where your water is coming from and how much labour the system requires to operate. Dragline irrigation or movable pipe systems require far more ...

  • Conjunctive effect of water productivity and cultivation pattern on agricultural water management

    Agricultural water resources are scarce in Iran, and agricultural water management is essential to overcome this limitation. Determination of the water productivity index (WP) using the methods of optimization of cropping patterns and optimal water allocation is the most effective tool in water management in the agricultural sector. In this study, a non-linear optimization model was used to ...

  • Impact analysis of reducing multi-provincial irrigation subsidies in China: a policy simulation based on a CGE model

    Water pricing policy is believed to be an efficient method for addressing the water scarcity problem in China. The motivation of this study is to provide a better understanding of how reducing irrigation subsidies impacts farming sectors and rural households. We apply a Computable General Equilibrium model to simulate the irrigation water and irrigation subsidy in 16 provinces. The results ...

  • Factors influencing water-use security among smallholder irrigating farmers in Msinga, KwaZulu-Natal Province

    This study investigates the physical, socio-economic and institutional factors affecting water-use security among irrigating smallholder farmers in Msinga Local Municipality to recommend policy. Cluster analysis was used to classify farmers according to their water-use security status. The logit model was then used to investigate the socio-economic factors influencing farmers' water-use ...

  • Measuring drought based on a CGE model with multi-regional irrigation water

    There have been many droughts in China that have caused severe losses. Previous studies evaluating droughts were from meteorological and hydrological perspectives. We measure the Chinese drought of 2000 based on a static computable general equilibrium model of China's macroeconomy, which describes the relationships between drought, agricultural production, and rural households' welfare from an ...

  • Irrigation water demand and implications for groundwater pricing in Pakistan

    This study employs the positive mathematical programming (PMP) approach to estimate groundwater derived demand for irrigation using a cross-sectional dataset of 200 predominantly groundwater irrigated farms from the Punjab province of Pakistan. First, we find that the PMP optimal solution uses less water than what is available (being extracted) in order to make farmers allocate all the ...

  • Agricultural water vulnerability in rural Iran

    Water is an important factor of production and livelihood support in rural communities. Meanwhile, water shortage is a virtually common feature in many arid and semi-arid countries. It is also projected that water stress will be exacerbated in such regions because of climate change. The cumulative effects of these stressors can potentially increase agricultural water vulnerability (AWV). ...

  • Water pricing and irrigation across Europe: opportunities and constraints for adopting irrigation scheduling decision support systems

    Despite the plethora of irrigation scheduling decision support systems that have been developed over the past decades, there is little evidence of widespread adoption by farmers. This paper investigates the structural, institutional and political rigidities that affect the adoption of irrigation scheduling technologies in southern European countries and highlights the corresponding ...

  • Optimizing channel cross-section based on cat swarm optimization

    Optimal design of channel cross-section is an important task in the hydraulic design of open channels. The traditional methods and models which neglect the frost heave are trial procedures and may result in failure of channels in design of irrigation channels. To improve the total cost, reliability and effectiveness, the model which is used in this study, is not only minimizing the cost of ...

  • Technical coefficients of direct use of water in monetary terms for agriculture and urban water use

    The San Francisco Integration Project is a Brazilian government project aiming to bring water to the semiarid region of the northeast. The project provides funding for two diversions of the San Francisco River, supplementing the supply of local water in four Brazilian states. The Piranhas-Açú and Jaguaribe basins will become the largest recipients of these water deliveries. In this paper, we ...

  • An assessment of farmers' willingness to participate in water trading in southern Spain

    This study applies contingent valuation to assess farmers' willingness to trade irrigation water. We analyse farmers' willingness to pay for water and their willingness to accept the selling of water through a seasonal market, under both normal rainfall and drought conditions. A survey of 241 farmers (irrigators and non-irrigators) in the Guadalquivir River Basin and in the ...

  • Water use efficiency and productivity of habanero pepper (Capsicum chinense Jacq.) based on two transplanting dates

    Habanero pepper production was assessed with drip irrigation and plastic mulch, based on two transplanting dates. The objectives of the study were: (i) to evaluate the effect of two transplanting dates and the use of plastic mulch on water productivity and habanero pepper fruit yield under drip irrigation conditions; and (ii) to determine the profitability and economic viability of the product ...

  • Can drip irrigation keep the Prairie Profitable?

    The use of flood and center pivot irrigation of crops via the waters of the Ogallala Aquifer is as hot a discussion topic as the current drought. To many who mine the aquifer to make a living, trying to keep a profitable way of life sustainable in a time when the broader public is seeking more conservation of resources yet wanting inexpensive, plentiful and safe food is problematic. Perhaps it's ...

  • The effects of irrigation modernization on the cost recovery of water in the Valencia Region (Spain)

    The modernization of the irrigation systems has been the main strategy followed by the regional administration of the Valencia Region to cope with the structural water deficit of the region, which has been particularly severe during the last three decades. These policies have been oriented to the substitution of gravity irrigation systems for drip technology. The technological change has ...

  • Grain Yields Starting to Plateau

    By Lester R. Brown From the beginning of agriculture until the mid-twentieth century, growth in the world grain harvest came almost entirely from expanding the cultivated area. Rises in land productivity were too slow to be visible within a single generation. It is only within the last 60 years or so that rising yields have replaced area expansion as the principal source of growth in world grain ...
