  • Fenton's treatment of actual agriculture runoff water containing herbicides

    This research was to study the efficiency of the Fenton's treatment process for the removal of three herbicides, namely 2,4-dichlorophenoxy acetic acid (2,4-D), ametryn and dicamba from the sugarcane field runoff water. The treatment process was designed with the Taguchi approach by varying the four factors such as H2O2/COD (1–3.5), H2O2/Fe2+ (5–50), pH ...

  • The response of phytoplankton and microlayer-adapted bacteria to monolayer application in a humic, eutrophic irrigation dam

    Repeat applications of artificial monolayers to farm irrigation dams to reduce evaporative loss may adversely affect water quality by enhancing populations of microlayer-adapted bacteria and blue-green algae. The microlayer, subsurface and water column of a 16 ha dam were monitored every two weeks for 18 months, to benchmark the seasonal dynamics of phytoplankton and microlayer-adapted ...

  • Different Asias, same problems: negotiating the state-user interface in surface irrigation in China and India

    This paper explores the dynamic interface of state-water users' relationships in large-scale surface irrigation in India and China, to inquire to what extent the issues encountered in large-scale irrigation management and governance are independent of regime characteristics. Though operating in very different overall political regimes, China and India exhibit strong similarities in the way a ...

  • Effects of drip irrigation promotion policies on water use and irrigation costs in Valencia, Spain

    The aim of this study is to conduct an ex post analysis of the generalized implementation of drip irrigation in the last two decades in the Valencia Region (Spain). Due to the important role played by water users' associations (WUAs) in this socio-technological change in the region, this research was based on 77 interviews with different WUAs that provided information prior and subsequent to ...

  • Are agricultural chemicals affecting our water?

    With the rate at which modern towns and cities expand it’s inevitable that the volume of separation between agricultural facilities and highly populated areas is shrinking. The loss of these areas can have a lasting impact, particularly when it comes to our water supplies. From an ...

  • Monitoring Water Resources Beyond Irrigation

    Over the past year, California’s governor has taken unprecedented action, requiring Californians to drastically cut potable urban water use. While the restrictions may seem harsh to some, it actually provides an opportunity for building managers and community association boards to implement an effective long-term water conservation program. And the result can be significant dollar savings. ...

  • Exploring Northwest China's agricultural water-saving strategy: analysis of water use efficiency based on an SE-DEA model conducted in Xi'an, Shaanxi Province

    Worldwide, water scarcity threatens delivery of water to urban centers. Increasing water use efficiency (WUE) is often recommended to reduce water demand, especially in water-scarce areas. In this paper, agricultural water use efficiency (AWUE) is examined using the super-efficient data envelopment analysis (DEA) approach in Xi'an in Northwest China at a temporal and spatial level. The grey ...

  • Estimating the ratio of pond size to irrigated soybean land in Mississippi: a case study

    Although more on-farm storage ponds have been constructed in recent years to mitigate groundwater resources depletion in Mississippi, little effort has been devoted to estimating the ratio of on-farm water storage pond size to irrigated crop land based on pond metrics and its hydrogeological conditions. In this study, two simulation scenarios were chosen to determine such a ratio as well as to ...

  • 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 ...

  • A distributed hydrological model in the Heihe River basin and its potential for estimating the required irrigation water

    A Grid-based Integrated Surface–Groundwater Model (GISMOD) was developed to estimate the required irrigation water using a control-site method. The entire catchment is divided into multiple grid cells of equal size, and several grid cells can be chosen as the control sites by users in this model. The grid cells from the upper stream of each control site, which have a land-use type of farmland, ...

  • 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 ...

  • Impact of irrigation water scarcity on rural household food security and income in Pakistan

    As Pakistan is currently facing a severe shortage of irrigation water, this paper analyzes the determinants of water scarcity and its impact on the yield of cereal crops (wheat, maize and rice), household income, food security and poverty levels by employing the propensity-score-matching approach. This study is based on a comprehensive set of cross-sectional data collected from 950 farmers ...

  • 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). ...

  • 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 ...

  • Assessing the regional food insecurity in Bangladesh due to irrigation water shortage in the Teesta catchment area

    Bangladesh is losing huge food production from the Teesta catchment area due to a lack of availability of irrigation water in the dry and lean period because of unilateral water withdrawal in the upstream country, India. The area, which is directly dependent on the irrigation water of the Teesta river, is the study area for this paper. The study reveals that rice production in Dalia, ...
