The was conducted at Hydro Farm MotorKing Company Limited Tamale Metropolis, Northern Region, Ghana. experimental design 2 × 3 factorial experiment laid out randomized complete block...
تخصیص بهینه منابع آب جهت مدیریت عرضه و تقاضا و بررسی تاثیر پدیده تغییر اقلیم بر سامانههای آبی امری ضروریست. هدف تحقیق، شبیه-سازی و بهینهسازی مولفههای سامانه آبی اهرچای تحت شرایط تغییر اقلیم و ارزیابی سناریوهای مختلف اقلیمی و مدیریتی جهت تصمیمگیری است. ابتدا اثر تغییر اقلیم بر متغیرهای هواشناسی با مدلهای گردش عمومی جو (GCMs) تحت سناریوهای A1B، A2 و B1 بررسی میگردد. نتایج این مدل تحت سناریو...
Abstract Failure in Environmental flow quantity, timing, and quality leads to failure support ecosystems, human livelihoods, well-being. Irrigation water use is one of the main actors impacting rivers quantity time but was not well investigated many ungauged catchments under smallholder irrigation systems. This study examined impact on environmental Arata's small catchment. The estimated sub-ca...
This paper presents a comprehensive study to assess the impact of climate change on Egypt’s water resources, focusing irrigation for agricultural crops, considering that agriculture sector is largest consumer in Egypt. The aims estimate future conditions using general circulation models (GCMs), and temperature increase demands CROPWAT 8 model, determine suitable type adapt with change. A case w...
Estimating the Water Footprint of the Four Important Cereal Crops in the Euphrates River Basin, Iraq
Abstract The footprint of water (WF) is a clear feature how much used during crops and commodity production other uses in industry human use. current research assessed discussed the average main 4 seven Iraqi Euphrates River basin provinces 2010–2020 years. levels blue green Water were calculated using Crop Requirement (CWR) option CROPWAT 8.0 software findings compared to global averages studi...
فضای سبز شهری به دلیل تنوع گونه های مختلف گیاهی موجود، پراکندگی محل قرارگیری آنها و همچنین تراکم های متفاوت این واحدها، همواره با چالشهایی برای برآورد نیاز آبی واقعی گیاهان روبهرو بوده است. در این پژوهش، نیاز آبی در سایت دانشگاه آزاد اسلامی واحد علوم و تحقیقات تهران با وسعت ha 4/109 برآورد شد. نخست تعداد 77 گونه گیاهی در سایت علوم و تحقیقات شناسایی گردید که از میان آنها گیاه ترون دارای ...
The response of the citrus crop to environmental supply largely determines speed and intensity plant's ecophysiological processes, which affect development production crop. main objective was analyze effects climatic conditions on productivity ‘Valencia’ orange agroecosystems (Citrus sinensis L. Osbeck) previously typified in department Meta, Colombia. climatological variables precipitation (PP...
Abstract Background Rainfall is the key contributor to provide soil moisture for wet season rice (T. Aman) cultivation. Erratic rainfall often causes water shortage resulting negative impact on plant growth and grain yield. The study aimed determine suitable transplanting window that utilize maximum T. Aman rice. Firstly, three years field experiment were conducted in Kushtia, Bangladesh from A...
Understanding future changes in water supply and requirement under climate change is of great significance for long-term resource management agricultural planning. In this study, daily minimum temperature (Tmin), maximum (Tmax), solar radiation (Rad), precipitation 26 meteorological stations RCP4.5 RCP8.5 MIRCO5 the period 2021–2080 were downscaled by LARS-WG model, average relative humidity (R...
