Abstract

Availability of irrigation water is considered one of the major challenges faced by Egypt during current time and will be more difficult in the future with the limited water resources and linearly increase of population. The current study investigates irrigation demand for sugarcane cultivation areas in the Middle and Upper Egypt Governorates (Menia, Asyut, Sohag, Qena, Luxor and Aswan) during current time and under RCPs scenarios. The current data was collected from 1971 till 2000. The RCP data were collected for different scenarios (RCP 3, RCP 4.5, RCP 6 and RCP 8.5) during three time series (2011-2040, 2041-2070 and 2071-2100). The highest evapotranspiration values during current and future conditions was found in Luxor and Aswan governorates; while the lowest evapotranspiration values were recorded in Menia and Asyut. All RCPs scenarios were significantly higher than current conditions. Moreover, the highest irrigation requirements under RCP scenarios were recorded in Aswan and Luxor under RCP 8.5 during 2071-2100 time series. While the lowest irrigation requirement under climate change were found in Menia under RCP3 during 2011-2040 time series. Irrigation requirement for sugarcane under current and future condition was demonstrated by interpolated maps.

气候变化对埃及甘蔗作物经济和灌溉需求的影响

灌溉水的可用性被认为是埃及目前面临的主要挑战之一，随着水资源的有限和人口的线性增长，未来灌溉水的供应将更加困难。本研究调查了埃及中部和上部省（Menia、Asyut、Sohag、Qena、Luxor和Aswan）甘蔗种植区在当前时间和RCP情景下的灌溉需求。目前的数据收集于1971年至2000年。在三个时间序列（2011-2040、2041-2070和2071-2100）期间，收集了不同情景（RCP 3、RCP 4.5、RCP 6和RCP 8.5）的RCP数据。卢克索省和阿斯旺省在当前和未来条件下的蒸发蒸腾量最高；而Menia和Asyut的蒸发蒸腾量最低。所有RCP情景均显著高于当前情况。此外，在2071-2100年的时间序列中，根据RCP 8.5，阿斯旺和卢克索记录了RCP情景下的最高灌溉需求。而在2011-2040年的时间序列中，在RCP3下，梅尼亚的灌溉需求在气候变化下最低。通过插值图证明了当前和未来条件下甘蔗的灌溉需求。

期刊介绍： Future of Food: Journal on Food, Agriculture & Society (FOFJ) was founded in 2012 in order to provide a platform for scientific debate on agriculture and food-related themes with the goal of a sustainable future for people and planet. The journal is aimed at contributing to debates on sustainable food production and consumption, and is most interested in tackling the most important challenges to the global agri-food system, such as hunger and malnutrition, depletion of natural resources, climate change, threats to biodiversity, and inequity in the agrarian sphere. The journal understands itself as a multi-disciplinary effort and is especially designed to foster interaction between different disciplines and approaches. Hence it invites inputs from social and natural sciences, arts and humanities, academics and scholar-activists, civil society and agroecology practitioners. The journal is attempting to reach its goal by providing open access to readers and allowing contributions without submission fees or publication fees. Contributors are kindly asked to keep in mind that the journal is a non-profit endeavour and that staff time is limited. The journal cannot provide guarantees or financial support for any submission and cannot accept legal responsibility for any stage of the submission process. The Editorial Board is made up by a range of international experts who devote time and energy to peer review and its members deserve gratitude and recognition for their excellent work. All communication between authors, editors, reviewers and editorial staff is conducted in an atmosphere of mutual respect. The journal will not tolerate racism, religious, ethnic and national chauvinism, misogynous and hate language and reserves the right to bar anyone who disrespects these principles from using the platform.
