“…Consequently, due to these variations the rate of crop evapotranspiration will increase which could create more worse scenario for crop production due to lesser water availability to fulfill crop water needs ( Abbas et al, 2017 , Ahmad et al, 2017 , Ahmad et al, 2019 , Fatima et al, 2020 , Fatima et al, 2021 ). This will lead to high risk of lesser crop production ( Ahmed et al, 2020 , Ahmed, 2020 , Zampieri et al, 2020 ) and consequently declined water productivity ( Ali et al, 2020 , Amiri et al, 2021 ). Determinantal impact of climate change and drought on food and water security have been reported by Ding et al (2021) .…”

Drought is a major and constantly increasing abiotic stress factor, thus limiting chickpea production. Like other crops, Kabuli Chickpea genotypes are screened for drought stress through Multi-environment trials (METs). Although, METs analysis is generally executed taking into account only one trait, which provides less significant reliability for the recommendation of genotypes as compared to multi trait-based analysis. Multi trait-based analysis could be used to recommend genotypes across diverse environments. Hence, current research was conducted for selection of superior genotypes through multi-trait stability index (MTSI) by using mixed and fixed effect models under six diverse environments. The genotypic stability was computed for all traits individually using the weighted average of absolute scores from the singular value decomposition of the matrix of best linear unbiased predictions for the genotype vs environment interaction (GEI) effects produced by a linear mixed-effect model index. A superiority index, WAASBY was measured to reflect the MPS (Mean performance and stability). The selection differential for the WAASBY index was 11.2%, 18.49% and 23.30% for grain yield (GY), primary branches per plant (PBP) and Stomatal Conductance (STOMA) respectively. Positive selection differential (0.80% ≤ selection differential ≤ 13.00%) were examined for traits averaged desired to be increased and negative (-0.57% ≤ selection differential ≤ -0.23%) for those traits desired to be reduced. The MTSI may be valuable to the plant breeders for the selection of genotypes based on many characters as being strong and simple selection process. Analysis of MTSI for multiple environments revealed that, the genotypes G20, G86, G31, G28, G116, G12, G105, G45, G50, G10, G30, G117, G81, G48, G85, G17, G32, G4, and G37 were the most stable and high yielding out of 120 chickpea genotypes, probably due to high MPS of selected traits under various environments. It is concluded that identified traits can be utilized as genitors in hybridization programs for the development of drought tolerant Kabuli Chickpea breeding material.

“…Mahrous (2018) studied the effect of climate change on Egypt's grain productivity using Autoregressive Distributed Lags Model (ARDL) during the period (1961:2013); the results revealed that rainfall and temperature had a significant negative impact, a 1% increase in rainfall and temperature leading to decrease the agricultural productivity of grain by 0.037% and 0.643%, respectively. Ali et al (2020) inferred that the reduction in Egyptian wheat yield is about 8.7%, 11.4%, and 13.2% in the 2030s, 2050s, and 2080s, respectively. The study proposed the sowing delay mechanism as one of the effective mechanisms for adapting the wheat to the climate changes using the Global Climate Models GCMs and Decision Support System for Agro-technology Transfer (DSSAT).…”

Climate change has adverse effect on agricultural production in developing countries, especially in those with low incomes and a high rate of hunger and poverty. Although the agricultural sector will be costly to adapt to climate change, it is essential to achieving food security. This study aims to analysis the impact of climate change on agriculture and adaptation mechanisms in Egypt during the period (1980:2018) using Autoregressive Distributed Lags Model (ARDL). The empirical results inferred that most of the variables are insignificant in the short-run. In the long run, the empirical results revealed that the impact of climate change on agricultural production, including the emissions of carbon dioxide and temperature, is positive. Hence, even if the impact of the rain variable is negative, but its value is low, and then Egypt has not entered a critical or dangerous stage. On the other hand, the results indicated that the research directed at increasing productivity and developing new varieties more compatible with climate changes is insufficient. Even if the research is available, the Egyptian farmer does not use it due to lack of agricultural Extension. For mechanical and chemical technology effect, the long-run coefficient of Fertilizers is insignificant. The long-run coefficient of the number of tractors is negative and significant, while rural population coefficient is positive and significant. This means that Egyptian agriculture is more dependent on manpower than mechanical technology

“…The combination of increasing sea level rise, saltwater intrusion and progressive groundwater extraction cause the largest reduction in fresh groundwater resources (Mabrouk et al, 2018). Regional climate models predict temperature rises (of 1.6 ± 0.6 °C by 2050, and 2.6 ± 1.0 °C in the Nile delta by the end of the century and occurrence of more frequent heat extremes may have direct negative impacts on wheat yields and other crops (Ter Maat & Wolters, 2016;Ali et al, 2020;Fawaz & Soliman, 2016;Omar et al, 2021).…”

Unravelling the interplay between water and food systems in arid and semi-arid environments: the case of Egypt

et al. 2021

Food system analysis in arid and semi-arid countries inevitably meets water availability as a major constraining food system driver. Many such countries are net food importers using food subsidy systems, as water resources do not allow national food self-sufficiency. As this leaves countries in a position of dependency on international markets, prices and export bans, it is imperative that every domestic drop of water is used efficiently. In addition, policies can be geared towards ‘water footprints’, where water use efficiency is not just evaluated at the field level but also at the level of trade and import/export. In this paper, Egyptian food systems are described based on production, distribution and consumption statistics, key drivers and food system outcomes, i.e., health, sustainable land and water use, and inclusiveness. This is done for three coarsely defined Egyptian food systems: traditional, transitional and modern. A water footprint analysis then shows that for four MENA countries, differences occur between national green and blue water volumes, and the volumes imported through imported foods. Egypt has by far the largest blue water volume, but on a per capita basis, other countries are even more water limited. Then for Egypt, the approach is applied to the wheat and poultry sectors. They show opportunities but also limitations when it comes to projected increased water and food needs in the future. An intervention strategy is proposed that looks into strategies to get more out of the food system components production, distribution and consumption. On top of that food subsidy policies as well as smart water footprint application may lead to a set of combined policies that may lead to synergies between the three food system outcomes, paving the way to desirable food system transformation pathways.
