Requisite simplicities to help negotiate complex problems. (3/70)

Decision makers responsible for natural resource management often complain that science delivers fragmented information that is not useful at the scale of implementation. We offer a way of negotiating complex problems by putting forward a requisite simplicity. A requisite simplicity attempts to discard some detail, while retaining conceptual clarity and scientific rigor, and helps us move to a new position where we can benefit from new knowledge. We illustrate the above using three case studies: elephant densities and vegetation change in a national park, the use of rules of thumb to support decision making in agriculture, and the management of salt in irrigation. We identify potential requisite simplicities that can allow us to generate new understanding, lead to action and provide opportunities for structured learning.  (+info)

Treated wastewater reuse for irrigation has gained a greater significance as an alternative resource to meet the growing water demands for agriculture and reduce the pressure on limited existing fresh water. However, this reuse needs adapted management in order to avoid environmental and health risks. An experiment was conducted in a greenhouse to evaluate the effect of different irrigation methods on the Metallic Trace elements and metals concentrations of a Tunisian soil (pH = 8.6) and corn when using treated wastewater. Four irrigation methods: surface irrigation, sprinkler irrigation, drip irrigation and subsurface drip irrigation, and two water qualities were used: treated wastewater and fresh water. Samples of soil and corn were analyzed for several Metallic Trace elements. Results for soil showed that treated wastewater increased electrical conductivity, nutrients and metallic trace elements. The highest levels of salinity and Metallic Trace elements were recorded with using surface ...
ENGLISH ABSTRACT: Food-borne disease outbreaks caused by Escherichia coli have been linked to the use of faecally-polluted irrigation waters. Thus the overall aim of this research was to evaluate irrigation water and agricultural effluents as sources of antibiotic resistant E. coli in the Western Cape. The aim of the first study was to enumerate and characterise E. coli present in irrigation water and in potential contamination sources. Maximum total coliform and E. coli counts for irrigation sites was log 7.862 and log 5.364 MPN.100 mL-1, respectively. Five out of seven irrigation sites had E. coli counts exceeding national and international guidelines for safe irrigation water (,1 000 counts.100 mL-1), making it unsafe for the irrigation of fresh produce. In this study, 46.6% of the E. coli strains were characterised in phylogenetic group B1. It has been shown that E. coli in group B1 have the ability to survive and persist in the external environment. Group B1 was also the most common group ...
Accurate accounting of irrigation water use is an important part of the U.S. Geological Survey National Water-Use Information Program and the WaterSMART initiative to help maintain sustainable water resources in the Nation. Irrigation water use in the humid eastern United States is not well characterized because of inadequate reporting and wide variability associated with climate, soils, crops, and farming practices. To better understand irrigation water use in the eastern United States, two types of predictive models were developed and compared by using metered irrigation water-use data for corn, cotton, peanut, and soybean crops in Georgia and turf farms in Rhode Island. Reliable metered irrigation data were limited to these areas. The first predictive model that was developed uses logistic regression to predict the occurrence of irrigation on the basis of antecedent climate conditions. Logistic regression equations were developed for corn, cotton, peanut, and soybean crops by using weekly irrigation.
Tree growth, fruit production and population dynamics of three root-knot nematodes, Meloidogyne incognita, M. arenaria and M. javanica were evaluated during six years in a peach planting. The treatments were: 1) preplant soil fumigation with methyl bromide at 450 kg/ha + mycorrhizae at planting, 2) root-knot nematode + Dactylella oviparasitica (S isolate), 3) root-knot nematode + soil from an established peach orchard, and 4) root-knot nematode alone. These four treatments were evaluated under normal and high irrigation regimes. Methyl bromide treatment improved tree growth, fruit production, and nematode control most. D. oviparasitica did not improve growth. The high irrigation regime counteracted the detrimental effects of root-knot nematode without reducing the nematode population. After 6 years root-knot nematode numbers were declining in all treatments except those previously free of the nematode.
Using pressure plate and membrane apparatus, irrigation regime of -500kPa was calculated. Forty AM fungal isolates were tested based on their peroxidase activity in soybean plant. Among the AMF, the soybean plants which received UASDAMFS1 (3.86 U mg-1 protein) exhibited less peroxidase activity compared to non mycorhized soybean plants which recorded the highest peroxidase activity (5.06 U mg-1 protein) at irrigation regime of -500 kPa. Total dry matter accumulation in plants was also recorded.
Impact of regulated deficit irrigation on the physiological characteristics of two rapeseed varieties as affected by different potassium rates
Due to climate changes and increased demands of different water users (agriculture, industry, domestic) water becomes scarce resources worldwide. Since irrigated agriculture is the one of the largest consumer of these resources (so called blue water footprint), irrigation management must be shifted from maximal production per crop area to maximal production per unit of water used by crops. Among the strategies for reducing water footprints, changing the full irrigation to the reduced crops water supply (deficit irrigation techniques) is one of the options. In this mini-review we present the latest advances of partial root-zone drying (PRD) applications in different agricultural plants, with the special emphases on the PRD effects on increasing WUE, yield and yield quality. We describe two PRD practical approaches (alternate and fixed), background of PRD induced increase in yield and water use efficiency and improved understanding about nutrient use efficiency. The evidence of PRD effect on the increase
The impact of water deficit on berry quality has been extensively investigated during the last decades. Nonetheless, there is a scarcity of knowledge on the performance of varieties exposed to a combination of high temperatures/water stress during the growing season and under vineyard conditions. The objective of this research was to investigate the effects of two irrigation regimes, sustained deficit irrigation (SDI, 30% ETc) and regulated deficit irrigation (RDI, 15% ETc) and of two cluster positions within the canopy (east- and west-exposed sides) on berry ripening in red Aragonez (Tempranillo) grapevines. The study was undertaken for two successive years in a commercial vineyard in South Portugal, monitoring the following parameters: pre-dawn leaf water potential, berry temperature, sugars, polyphenols, abscisic acid (ABA) and related metabolites. Additionally, expression patterns for different transcripts encoding for enzymes responsible for anthocyanin and ABA biosynthesis (VviUFGT, VvNCED1,

The role of irrigation water in disseminating Erwinia amylovora is not fully recognized, and the survival of the bacterium in natural water has not been carefully investigated. This risk has been underestimated, since it is generally considered that E. amylovora survives only for a short period in water and its isolation from natural water samples has not been reported. The main goal of this study has been to clarify whether E. amylovora could survive under nutrient starvation conditions usually found in aquatic environments and if it is nonculturable on solid media when recovered from sterile natural water. Infectivity of E. amylovora cells in water was evaluated by using immature pear fruits. Total and viable cell counts were monitored by the Live/Dead viability kit, and culturability by plate counts on King's B medium. E. amylovora was able to survive in water from different sources showing a long persistence in irrigation water and maintaining its infectivity for green pears. However, a ...

Quantifying sap fluxes and ABA concentrations of xylem saps collected from different parts of the root system may assist in modelling leaf xylem ABA concentration ([X-ABA](leaf)) of plants grown with heterogeneous soil moisture distribution. To investigate the contribution of different parts of the root system to total sap flow and [X-ABA](leaf), individual shoots were grafted onto the root systems of two plants grown in two separate compartments and sap flow sensors placed on each hypocotyl below the graft union. Two different irrigation regimes were imposed: conventional deficit irrigation (DI) where both pots received the same volumes of water, and partial rootzone drying (PRD) where only one pot (designated "wet") was watered and other (designated "dry") dried the substrate. In plants grown in 3 L pots that were vertically divided into two watertight compartments, soil water content (theta) and sap flow were continuously monitored. In plants grown in 2 appressed 0.43 L pots, xylem sap was ...
This paper examines land use policy and agricultural water management in Africa from 1962 to 2011. For this purpose, data were gathered from Food and Agriculture Organization of the United Nations (FAO) and the World Bank Group.

Managing irrigation systems requires understanding crop water usage. Read about estimating crop water use rates, and factors affecting water use.
Downloadable! Over-allocation of fresh water resources to consumptive uses, coupled with recurring drought and the prospect of climate change, is compromising the stocks of natural capital in the worlds basins and reducing their ability to provide ecosystem services. To combat this, governments world wide are making significant investment in efforts to improve sharing of water between consumptive uses and the environment, with many investments centred on modernisation of inefficient irrigation delivery systems, and the purchase of water by government for environmental flows. In this study, spatial targeting was applied within a cost-benefit framework to reconfigure agricultural land use in an irrigation district to achieve a 20% reduction in agricultural water use to increase environmental flows and improve the provision of other ecosystem services. We demonstrate using spatial planning and optimisation models that a targeted land use reconfiguration policy approach could potentially increase the net
Traditionally, irrigation water is grouped into various quality classes in order to guide the user to the potential advantages as well as problems associated with its use and to achieve optimum crop production. The water quality classifications are only indicative guidelines and their application will have to be adjusted to conditions that prevail in the field. This is so because the conditions of water use in irrigation are very complex and difficult to predict. The suitability of water for irrigation will greatly depend on the climatic conditions, physical and chemical properties of the soil, the salt tolerance of the crop grown and the management practices. Thus, classification of water for irrigation will always be general in nature and applicable under average use conditions. Many schemes of classification for irrigation water have been proposed. Ayers and Westcot (FAO 1985) classified irrigation water into three groups based on salinity, sodicity, toxicity and miscellaneous hazards, as ...
This ratio quantifies the proportion of sodium (Na+) to calcium (Ca++) and magnesium (Mg++) ions in a water sample. In the soil, calcium will flocculate (hold together), while sodium disperses (pushes apart) soil particles leading to poor soil condition. Many factors including soil texture, organic matter, crop type, climate, irrigation system, and management impact how sodium in irrigation water affects soils. Sodium in irrigation water can cause toxicity problems for some crops, especially when the water is applied with a sprinkler system. SAR and ECw are interdependent and thus irrigation suitability is characterized by both values. The following is a breakdown of the general classifications of irrigation water based upon the SAR values. Course Sand to Fine Sandy Loam: maximum EC of 3000 micromhos per centimeter and maximum SAR of 12; Loam and Silt Loam: maximum EC of 3000 micromhos per centimeter and maximum SAR of 9; Very Fine Sandy Loam to Silty Clay Loam: maximum EC of 2250 micromhos per ...

Grant County, WA) Landau Associates is assisting Four Cross Ranch to obtain Article 28 and Phase I Water Service contracts with the Quincy-Columbia Basin Irrigation District (QCBID) to develop over 1,500 acres of center pivots in the High Hills area of Irrigation Block 91 in the north portion of the Quincy Basin. Water Service contract issuance is contingent on drainage approval from the Bureau of Reclamation. The High Hills is a 14-square mile area between lower Grand Coulee and Dry Coulee and directly above Soap Lake. The lake is unique in that it has no surface water inlet or outlet and no groundwater outlet (all inflow is from groundwater; all discharge is from evaporation). Initial development of the Columbia Basin Project in the late 1940s and early 1950s led to flooding of Soap Lake and a decrease in salinity. The Bureau had deferred irrigation of the High Hills because of the unknown impact of irrigation return flows from spray irrigation on recharge to Soap Lake. Stratigraphy beneath ...
Furthermore, the assumption is made that 100 ha of land is available for the production of maize while 2 water supply scenarios are considered. Scenario 1 is characterised by a situation where enough water is available to irrigate 100 ha of maize without sustaining any crop yield loss due to salinity (α = 1). Thus, the farmer needs to reduce his area irrigated to release water for leaching purposes when irrigation water quality deteriorates further. With Scenario 2 water supply is assumed to be 10% more than that of Scenario 1 (α = 1.1). However, the area that can be irrigated remains at 100 ha. Scenario 1. Figure 2 shows the tradeoff that exists between deteriorating irrigation water salinity and the on-farm margin above specified costs (a), the marginal value of irrigation water (b), soil water salinity (c), amount of water used to leach excess salt from the soil (d), the area under production (e) and crop yield (f). The results in the graphs show that no tradeoff is modelled when the ...

Beyond Pesticides has investigated treated wastewater from homes and residential areas. This research indicates that treated wastewater acts as a prominent food contaminant when used for irrigation. While wastewater recycling has many benefits, there are a host of issues that must be addressed before using wastewater for irrigation can be considered safe. Chief among them is contaminants of emerging concern. Contaminants of emerging concern are chemicals that typically have not been monitored in the environment, but have only recently been detected in waterways and municipal wastewater. Chemicals include are flame retardants, personal care products, pharmaceuticals, and pesticides.

4) Drip nozzles.. The head consists of a pump to lift water and produce the desired pressure (about 2.5 tmosphere) and to distribute water through nozzles. A fertilizer tank for applying fertilizer solution directly to the field along with the irrigation water and filter which cleans the suspended impurities in irrigation water to prevent the blockage of holes and passage of drip and nozzles. Mains and sub mains are normally of flexible material such as black PVC pipes. Laterals or drip lines are small diameter flexible lines (usually 1 to 1.25 cm diameter black PVC tubes) taking off from the mains or sub mains. Laterals are normally laid parallel to each other. Lateral lines can be up to about 50 meters long and are usually 1.2 cm diameter black plastic tubing. There is usually one lateral line for each crop row. By laying the main line along the center line of the field, it is possible to irrigate either side of the field alternately by shifting the laterals. A pressure drop of 10 percent is ...
The growing threat of drought and rising water demand have made accurate forecasts of crop water use critical for farmland water management and sustainability.. But limitations in existing models and satellite data pose challenges for precise estimates of evapotranspiration-a combination of evaporation from soil and transpiration from plants. The process is complex and difficult to model, and existing remote-sensing data cant provide accurate, high-resolution information on a daily basis.. A new high-resolution mapping framework called BESS-STAIR promises to do just that, around the globe. BESS-STAIR is composed of a satellite-driven biophysical model integrating plants water, carbon and energy cycles - the Breathing Earth System Simulator (BESS) - with a generic and fully automated fusion algorithm called STAIR (SaTellite dAta IntegRation).. The framework, developed by researchers with the U.S. Department of Energys Center for Advanced Bioenergy and Bioproducts Innovation (CABBI) at the ...
Figure 2. Definition Sketch of an Irrigation System The approach which has been applied to irrigated agricultural development in the past is characterized by separating the development of water resources from the management aspects of water resource utilization. Therefore, the record shows development being emphasized greatly while management is most often neglected. This orthodox approach has been used almost exclusively in the western United States with reasonable success. However, as water resources become more fully utilized, the necessity for meeting new water demands (along with physical, socioeconomic, and political problems of water quality degradation) require that we reject much of the conventional wisdom of the past. It should also be obvious that many other countries have neither the time nor the resources that many western irrigated regions had to utilize in their development. Pressures created by rapidly rising population rates alone will force them at some point to re-evaluate ...
The amount of energy saved through recycling depends upon the material being recycled and the type of energy accounting that is used. Correct accounting for this saved energy can be accomplished with life-cycle analysis using real energy values. In addition, exergy, which is a measure of useful energy can be used. In general, it takes far less energy to produce a unit mass of recycled materials than it does to make the same mass of virgin materials.[80][81][82]. Some scholars use emergy (spelled with an m) analysis, for example, budgets for the amount of energy of one kind (exergy) that is required to make or transform things into another kind of product or service. Emergy calculations take into account economics which can alter pure physics based results. Using emergy life-cycle analysis researchers have concluded that materials with large refining costs have the greatest potential for high recycle benefits. Moreover, the highest emergy efficiency accrues from systems geared toward material ...
Salinity management is particularly important in dry regions that rely on irrigation. Many irrigation operations recycle irrigation water. Over time, as water is recycled again and again, salt levels in the water build up and salt is deposited in the soil, which reduces the soils ability to absorb water and air. As salt levels in irrigated land increase, a white or black crust can form at the surface of the soil. Plants start to suffer damage when soil sodium concentration exceeds 230 milligrams per liter, and chloride concentrations in soil exceed 350 milligrams per liter. Periodic deep irrigation with fresh irrigation water helps remove salt from soil.. ...
The purpose of this study is to evaluate the efficiency of irrigation water use and allocation in the Waihou Catchment. It follows on from similar work for other parts of the Waikato Region. It will further extend the understanding of water use and allocation in the Region and contribute to the development of water management policy and planning.. The surface water resources of the Waihou Catchment are close to full allocation. Future demand for surface water will need to be met from improvements in efficiency of current water uses and allocations. Irrigation accounts for 50 percent of the daily take, and therefore any improvements in on-farm water use and/or allocations will be a major benefit. This is applicable to not only the Waihou Catchment, but also to other catchments where water resources are a constraint to future development.. Irrigation Efficiency and Water Allocation in the Waihou Catchment ...

Climate change is causing growing variability and uncertainty in rainfall in Africa. Since the continents food production systems are dominantly rain-fed, these changes are putting food security at even higher risk. In order to reduce this dependency, institutional reforms in the agricultural water sectors have become a priority in research and policy.. In this report, Atakilte Beyene, senior researcher at the Nordic Africa Institute, together with twelve researchers based in Africa, studies current agricultural water reforms in Kenya, Tanzania, Uganda, and other East African countries. The report consists of four case studies and an introductory section. The first case study evaluates the performance of community participation in water resources governance in the Mount Kenya Region. It uncovers the implication of a ban on traditional institutions on water security at a catchment level. The second case analyses the prospects of introducing pro-poor water schemes in conditions where climate ...

Actually, leaving water out in the sun may promote algae growth. The algae comes from stuff floating around in the air that gets in the water while you are filling the container. I have a 275 gallon LDPE tote on a trailer that I keep for wash water or other needs. I use groundwater from an aquifer about 75 ft. deep and this water is sterile when it is pumped from the well. Unless I disinfect the water in the tote, algae will start to grow and the water will turn green. Once disinfected, this doesnt happen, since the tote is capped and nothing gets in. I keep my irrigation water in blue LDPE drums that are opaque. I dont mind algae in my irrigation water, but it plugs the drippers ...
Water cards. Pink and light blue cards were used to represent water. One pink card was used as the equivalent to the volume of enough water to transplant and irrigate 0.1 ha of rice. Pink cards represented water used in the first cycle (first week of June to October) and light blue cards represented water used in the second cycle (third week of June to October). This means that farmers could place only one water card in one plot to indicate that that plot has been planted to rice. This card could be sold, exchanged, or used for transaction among villagers in a community or between farmers of the two communities. The game facilitator issued water cards in correspondence to the rainfall type. In the normal-rainfall season, Thruelpa received 5 water cards, Chhep 3 cards, Chatho 2 cards, and Lhangchu 1 card. During the low-rainfall pattern, the water provision was reduced by one unit, that is, 1 card less for each category ...
