Southwest AgricultureIntroductionSouthwest agriculture refers to the agricultural practices and systems in the southwestern region of a country. This region is known for its unique climate, topography, and agricultural techniques that are specifically adapted to the conditions found in the area. In this article, we will explore the characteristics of southwest agriculture, including the crops grown, irrigation methods used, and the challenges faced by farmers in this region.Characteristics of Southwest Agriculture1. Drought-resistant CropsDue to the arid and semi-arid climate in the southwest, farmers in this region mainly cultivate drought-resistant crops that can withstand the limited water availability. Some of the common crops grown in southwest agriculture include: - Maize - Sorghum - Millet - SunflowersThese crops have been genetically modified or selectively bred to have increased tolerance to drought conditions and require less water compared to other crops.2. Efficient Irrigation TechniquesWater scarcity is one of the biggest challenges faced by farmers in the southwest. To overcome this, innovative irrigation techniques have been developed and implemented in southwest agriculture. Some of these techniques include: - Drip Irrigation: This method provides water directly to the roots of the plants, reducing water wastage through evaporation. - Sprinkler Irrigation: In this method, water is sprayed over the crops in a manner that mimics rainfall, ensuring uniform distribution. - Terracing: Terraces are built on slopes to prevent soil erosion and maximize water retention.These techniques not only conserve water but also help in maximizing crop yields in the limited water availability.3. AgroforestryAgroforestry is another important aspect of southwest agriculture. It involves the integration of trees or shrubs with agricultural crops or livestock. This practice offers several benefits, such as: - Soil Conservation: Trees help prevent erosion and maintain soil fertility. - Microclimate Regulation: The presence of trees creates a microclimate that can moderate temperature and humidity levels, benefiting both crops and livestock. - Biodiversity Conservation: Agroforestry systems promote biodiversity by providing habitat for various species of plants and animals.Farmers in the southwest often adopt agroforestry techniques to enhance the sustainability and productivity of their agricultural systems.4. Pest and Disease ManagementThe warm climate and diverse ecosystems in the southwest make it a favorable environment for pests and diseases. Integrated pest management (IPM) strategies are employed to control these threats in southwest agriculture. IPM involves a combination of techniques such as: 1. Biological control: The use of natural enemies of pests, such as predators and parasites, to keep their populations in check. 2. Crop rotation: Changing the crops planted in a specific area helps break the lifecycle of pests and prevent the buildup of pathogens. 3. Cultural practices: Implementing practices like proper sanitation, weed control, and pruning to reduce pest and disease incidences. 4. Minimal use of pesticides: Chemical pesticides are used as a last resort and are carefully chosen to minimize environmental impact.These strategies promote sustainable pest and disease management, reducing the reliance on synthetic pesticides and minimizing harms to the ecosystem.Challenges Faced by Southwest Farmers1. Water ScarcityThe scarcity of water is a significant challenge faced by farmers in the southwest. With limited rainfall and inadequate water sources, farmers have to carefully manage their water resources and make use of efficient irrigation techniques to sustain their crops. Climate change exacerbates this issue, as extreme weather events like droughts become more frequent.2. Soil ErosionThe hilly topography and heavy rainfall in some parts of the southwest make soil erosion a common problem. Uncontrolled runoff can wash away fertile topsoil, reducing the soil’s productivity. Farmers employ various measures like terracing, contour plowing, and the use of cover crops to mitigate soil erosion and maintain soil health.3. Market AccessRemote locations and limited transportation infrastructure pose challenges in accessing markets for southwest farmers. The lack of proper roads and storage facilities can result in difficulties in transporting and selling agricultural produce. Improved infrastructure and better market linkages are essential to overcome this challenge and ensure a fair price for farmers’ products.4. Climate ChangeThe southwest region is vulnerable to the impacts of climate change, including changes in temperature, rainfall patterns, and the frequency of extreme weather events. Unpredictable weather conditions can disrupt crop seasons, affect yields, and increase the prevalence of pests and diseases. Farmers need to adapt their agricultural practices and adopt climate-resilient techniques to mitigate the impacts of climate change.In conclusion, southwest agriculture is characterized by the cultivation of drought-resistant crops, efficient water management techniques, agroforestry practices, and integrated pest and disease management.Despite the challenges posed by water scarcity, soil erosion, limited market access, and climate change, farmers in the southwest remain resilient and adapt their practices to ensure sustainable agricultural production in this unique region.。

drought 英语介绍What is Drought?Drought is a prolonged period of abnormally dry weather, resulting in a shortage of water supply for various uses such as irrigation, household consumption, and industrial processes. It is a natural disaster that can have severe impacts on ecosystems, agriculture, economies, and human lives. Droughts can occur in any climate zone and can range in duration, severity, and geographic extent. In this article, we will delve deeper into the causes, effects, and strategies for mitigating the impacts of drought.Causes of DroughtSeveral factors contribute to the onset of drought, including natural variability in climate patterns and anthropogenic activities. Natural causes of drought include weather patterns like El Niño and La Niña, which can disrupt rainfall patterns and lead to prolonged dry periods. Climate change also plays a role in increasing the frequency and intensity of droughts, altering precipitation patterns and exacerbating water scarcity in certain regions.Human activities can also contribute to the occurrence of drought. Deforestation, for instance, reduces the capacity of forests to retain water, leading to decreased water availability in adjacent areas. Additionally, excessive water consumption by agriculture and industrial sectors can deplete water sources, exacerbating drought conditions. Poor water management practices, such as inefficient irrigation methods and inadequate water storage infrastructure, can further amplify the impacts of drought.Effects of DroughtDrought can have extensive impacts on various sectors and ecosystems. The agricultural sector is particularly susceptible, as crops and livestock depend heavily on water for growth and sustenance. Droughts can lead to crop failures, reduced agricultural yields, and livestock deaths, causing food shortages and price hikes. In addition to the immediate economic consequences, the longterm effects of drought on agriculture can include soil degradation, reduced soil fertility, and loss of vegetation cover.Ecosystems also suffer during droughts, with decreased water availability disrupting natural processes and habitats. Rivers, lakes, and groundwaterreservoirs can dry up, threatening the survival of aquatic species and diminishing biodiversity. Forests become vulnerable to wildfires, as dry vegetation becomes highly flammable. Moreover, droughts can lead to ecological imbalances, such as invasive species proliferation, which can further harm native flora and fauna.Droughts also impact human lives and economies. Water scarcity affects human health and hygiene, with a higher risk of waterborne diseases. Indigenous communities and disadvantaged populations are particularly vulnerable, as they often lack access to alternative water sources or means to cope with the impacts of drought. Economic sectors such as energy production, manufacturing, and tourism can also suffer as water scarcity hampers operations, increases costs, and decreases productivity.Mitigation and Adaptation StrategiesTo mitigate the impacts of drought, a combination of preventive measures, water management strategies, and adaptive practices are necessary. Integrated water resources management (IWRM) plays a crucial role in drought mitigation by balancing water supply and demand. This involves improving water efficiency, implementing water conservation practices, and promoting sustainable water use across sectors.Investing in water storage infrastructure, such as dams and reservoirs, increases water availability during dry periods. Implementing watersaving technologies and encouraging practices like rainwater harvesting and wastewater reuse also contribute to mitigating the impacts of drought. Moreover, enhancing soil conservation practices, such as afforestation and conservation agriculture, can improve soil moisture retention and reduce the effects of drought on agriculture.In terms of adaptive measures, enhancing early warning systems, drought monitoring, and forecasting can enable timely preparedness and response actions. Government agencies, in collaboration with local communities, should develop drought contingency plans that outline water allocation priorities, emergency response measures, and alternative water sources. Diversifying water sources through investment in desalination plants, interbasin water transfers, and water recycling can help alleviate the impacts of drought.Building resilience to drought also requires raising awareness and educating the public about water conservation practices and sustainable water use. Encouraging behavioral changes and promoting watersaving habits at home, schools, and workplaces can contribute to longterm watersecurity. Additionally, supporting research and innovation in waterrelated technologies and practices can lead to more efficient and sustainable solutions for drought management.ConclusionDrought is a complex phenomenon that poses significant challenges to ecosystems, economies, and human wellbeing. Addressing the causes and impacts of drought requires a multidimensional approach that involves climate change mitigation, water management strategies, and adaptive measures. By implementing comprehensive and integrated solutions, societies can build resilience and ensure water security in the face of future drought events.。

这篇文章是用来测量马铃薯在微波和对流干燥进程中的质量和结构转变。
微波炉通过改良后,选择微波或对流干燥模式干燥样品。
脱水马铃薯样品的质量品质以抗坏血酸残留量(VC)、复水能力和具有收缩性的结构为准。
抗坏血酸马铃薯品质的重要指标,且与热变性有关。
抗坏血酸的恶化标志着一级反映情形,进一步的研究说明,取决于空气温度、微波力、湿度含量。
在微波干燥样品中,VC含量破坏减少。
样品的体积皱缩度显示其与湿度的线性关系。
在对流加工进程中,样品自始至终都会显现收缩性,但是,咱们却发觉微波干燥有两个收缩周期。
微波干燥样品有更高的复水能力。
关键词:对流干燥; 微波干燥; 马铃薯; 复水; 缩水; 维生素C目录1.简介1.简介在微波加工进程中,食物品质是消费者关注的重要指标之一。
微波干燥食物能够提高复杂的化学转换、化学反映。
,这些反映能够致使维生素的分解,脂肪氧化和美拉德反映。
而这些反映机制能够受浓度、温度、水分活度(aw)阻碍()。
经调查研究发觉,在微波烹饪中维生素会有所减少。
曾研究讨论了微波食物及其相关食料的作用阻碍,微波量子能在各能级范围内比其他形式的电磁能(X- 和γ-射线)能量都低,也就使得分子和化学集团彼此作用从而引发化学转变。
把热灵敏和水溶性的维生素C 、B1和B2作为指示器来定性分析化学转变。
食物在微波炉中的烫熟、加热和再加热进程中其维生素残留量可与常规加热方式相较较。
研究发觉抗坏血酸的破坏速度随着aw值增加而增加,在解吸附系统中由于粘度的降低破坏速度会大大增加()。
研究发觉,在复水食物体系中,抗坏血酸的稳固性受水分活度、湿度、氧气、贮藏温度的阻碍。
在本文贮藏条件下,抗坏血酸的损失量与一级反映作用相一致。
研究发觉,真空微波干燥胡萝卜的VC残留量比空气微波干燥的残留量大。
也发觉了,秋菊微波干燥的抗坏血酸破坏量小。
原料内部电子能的消耗会产生热不平稳状态,从而引发不同反映,可是传统加热方式那么不然。
应用微波能够改良干燥速度,这能够说明为微波可诱导产生压力梯度,加速热移动进程从而改善产品的物理性质。

Drought Storage Allocation Rules for SurfaceReservoir SystemsJay R.Lund1Abstract:This technical note develops a simple drought storage allocation rule to minimize evaporative and seepage water losses from a system of reservoirs.Such a rule might have value during a prolonged drought,when the value of lost water is likely to be particularly high.Typically,concentrating water storage in one or a few reservoirs reduces overall water losses compared to“balancing”storage among reservoirs.Paradoxically,concentrating storage during a drought tends to minimize reservoir surface area available for recreation, increasing recreation losses even as it minimizes water losses.DOI:10.1061/͑ASCE͒0733-9496͑2006͒132:5͑395͒CE Database subject headings:Droughts;Reservoirs;Seepage.IntroductionReduction in evaporative and seepage losses from reservoirs is particularly important and valuable during a drought͑Kelley 1986͒.For a multireservoir system,can storage rules among res-ervoirs be devised to minimize such physical losses?Would such rules tend to distribute water among reservoirs or concentrate water storage in a single reservoir?This technical note explores this problem andfinds that for some fairly general circumstances, water losses are lessened if water storage is concentrated in a single reservoir depending,of course,on local constraints.Some potential socioeconomic losses from this water conservation strat-egy are also discussed.Reservoir Losses during a DroughtThe major losses of water from a reservoir during a drought are evaporation to the atmosphere and seepage to groundwater.These losses can be estimated for a reservoir in a valley with a very regular geometry,having valley side slopes of a and a longitudi-nal valley slope of b͑Fig.1͒.Here,Hϭdeepest depth of water in the reservoir͑at the dam͒;Wϭhalf width of the triangular water surface͑at the dam͒,and Lϭlongitudinal length of the water sur-face.While no single reservoir will ever have these characteris-tics,this shape is similar to that of many surface reservoirs.The surface area of this reservoir is A=LW,and its storage volume S=1/3LWH.We later compare this reservoir shape with those of several actual reservoirs.EvaporationEvaporative losses from a reservoir are generally taken to be proportional to the surface area of the reservoir,E=eA.By sub-stitution,Eq.͑1͒is the evaporative loss

geometry of reservoirJOURNAL OF WATER RESOURCES PLANNING AND MANAGEMENT©ASCE/SEPTEMBER/OCTOBER2006/395seepage is a loss of water available during a critical time.Seepage losses from the reservoir will need to flow under the dam or hillsides,and should be proportional to the head on the dam ͑by Darcy’s law ͒.With some algebra,this gives an approximate representation of seepage loss as a function of storage in the following equation:D =dͩ3S abͪ1/3͑2͒Marginal LossesIn developing an operating rule that minimizes losses,we would like to compare the additional loss from an additional unit of water placed in each reservoir ͑the marginal water loss ͒.These marginal losses are merely the first derivatives of Eqs.͑1͒and ͑2͒,appearing as Eqs.͑3͒and ͑4͒,respectivelydE dS =2e ͩab 3Sͪ1/3͑3͒dD dS =d 32/3͑ab ͒1/3S −2/3͑4͒Concave Loss–Storage RelationshipsThe above geometric reasoning indicates that while reservoir surface area and seepage head increase with storage,they increase at a diminishing marginal rate ͑second derivative is negative ͒.Surface area ͑and evaporation ͒and head on the reservoir are therefore concave functions of storage.This geometric result is generally confirmed for the storage–area relationships of 16large reservoirs in California,illustrated in Fig.2.Fig.3plots head–storage curves for the same reservoirs.This relationship is si-milarly concave.Reservoir losses generally tend to be concave functions of storage.Drought Storage RuleSince marginal losses from additional storage ͑second derivative of losses as a function of storage ͒generally decrease with increas-ing storage,losses will be minimized if,to the extent practicable,water is stored in one reservoir,rather than distributed amongmany.The particular reservoir ͑s ͒chosen for concentrating storage should be those with the least loss potential.Stated simply:“to minimize water losses during a drought,water storage should be concentrated in reservoir ͑s ͒with the least loss potential.”Balancing storage among reservoirs,a common practice where each reservoir is filled to a similar percentage of its overall ca-pacity,does not minimize water losses.Indeed,if all reservoirs in a system had the same loss–storage relationship,balancing stor-age among reservoirs would maximize water losses during a drought.The particular reservoirs where storage should be con-centrated to minimize water losses is likely to be driven by the combined effects of reservoir geometry and local surface evapo-ration and seepage rates.Only in systems where loss functions are convex would it make sense to balance water storage among reservoirs to minimize water losses.For mild or moderate droughts,where most reservoirs remain in the relatively linear portion of the relationships between surface area,head,and stor-age,the reductions of water loss from concentrating storage might be relatively small.Under severe drought,when storages tend to be in the more concave portions of these relationships and water is much more scarce,water loss reductions are more likely to justify operating rule modifications.Rule ImplicationsIn the course of a prolonged drought,it is often possible to shift some storage among reservoirs,whether directly ͑from upstream to downstream reservoirs ͒or by indirect means ͑such as wheeling releases among reservoirs in parallel or making all releases from downstream reservoirs while allowing upper reservoirs to fill,to the extent of available inflows ͒.For systems where it is difficult to move water among reservoirs during a drought,then perhaps it is worthwhile to arrange for carryover storage in a reservoir system to be distributed more according to loss minimization than according to spill minimization.Paradoxically,this rule for minimizing water losses by concen-trating drought storage in one or a few reservoirs will tend to exacerbate the appearance of drought,in terms of pictures of dry reservoirs on the evening news,and worsen some drought impacts,in terms of potential lost reservoir recreation benefits ͑which,like evaporation,also tends to be positively related to reservoir surface area ͒.Economic losses and politicalcontrover-Fig.2.Area–storage curves for 16large reservoirs inCaliforniaFig. 3.Head–storage curves for same 16large reservoirs in California396/JOURNAL OF WATER RESOURCES PLANNING AND MANAGEMENT ©ASCE /SEPTEMBER/OCTOBER 2006sies arising from recreation loss might mean that while concen-trating storage in the fewest number of reservoirs is physically optimal,it might not be economically or politically optimal.Similar difficulties can arise for hydropower,environmental, or other operating purposes.In addition,changes to normal stor-age operations to reduce evaporative or seepage losses are likely to require prearranged agreements with water-right holders,regu-lators,and other interested parties in a system.This points to the importance of having contingency plans and agreements in place before the occurrence of a drought.ConclusionsThis technical note develops a simple drought storage allocation rule to minimize evaporative and seepage water losses from a system of reservoirs.Such a rule is likely to be valuable during a prolonged drought,when the value of lost water is likely to be highest.Typically,concentrating water storage in one or a few reservoirs minimizes overall water losses compared to“bal-ancing”storage among reservoirs.Paradoxically,concentrating storage during a drought tends to minimize the overall reservoir surface area,which tends to minimize reservoir area available for recreation,and increase recreation losses,even as it minimizes water losses.Such rules are likely to require advance agreements to accommodate multiple water uses and right holders.
