“…Practical evidence can be found through several infrastructure projects that affect all dimensions of sustainability. For example, there exists valuable international discourse and research on the environmental impact of the Channel Tunnel [72], the climate's long-term impact on New Zealand infrastructure [73], the impact of the Grand Ethiopian Renaissance Dam on water resources [74], port connectivity between Burgas (Bulgaria) and Alexandroupolis (Greece) [34], land use in the Polavaram River project (India) [75], international security linkages over Turkey's Ilisu Dam [76], the re-settlement of China's Three Gorges Dam [77], and the UN on Infrastructure and Human Rights [78]. Some of these projects have been highly criticized for their environmental or social impact.…”

The Belt and Road Initiative is the leading project in the regions along the ancient Silk Road. This aims to revive the New Silk Road (NSR) as a transnational space towards an era of new regional integration and globalization. Despite the potential economic effects on a global scale, local sustainability remains questionable. Building upon the central engagement in infrastructure improvements, this article aims to investigate the role of local sustainability in research along the New Silk Road. Starting with 597 scientific articles, this article conducts a systematic literature review on four levels of concretization to characterize the research field of the New Silk Road, and to develop in-depth insights systematically. The results reveal a research focus on economic growth, which is lacking in environmental considerations and especially the socio-cultural dimension of sustainability on a local scale. Future directions in local sustainability should therefore include local stakeholders to build a joint understanding of sustainability by recognizing the characteristics of regionalism upon which manifold local support of mega infrastructure can evolve. Given these findings, the New Silk Road emerges as a field of study that calls for interdisciplinary research on different spatial levels.

“…Egypt is considered one of the most vulnerable countries facing the potential impacts of climate change [8], as the agriculture industry in Egypt consumes~84% of the country's water resources [9,10]. Egypt's agriculture mainly depends on irrigation from only one major source, the Nile River.…”

Developing and disseminating resilient rice cultivars with increased productivity is a key solution to the problem of limited natural resources such as land and water. We investigated trends in rice cultivation areas and the overall production in Egypt between 2000 and 2018. This study identified rice cultivars that showed potential for high productivity when cultivated under limited irrigation. The results indicated that there were significant annual reductions in both the rice-cultivated area (−1.7% per year) and the production (−1.9% per year) during the study period. Among the commonly cultivated varieties, Sakha101 showed the highest land unit productivity, while Sakha102 showed the highest water unit productivity. The impact of deploying new cultivars was analyzed by substitution scenarios. The results showed that substituting cultivars Giza179 and Sakha107 has the potential to increase land productivity by 15.8% and 22.6%, respectively. This could result in 0.8 million m3 in water savings compared to 2018 water consumption. Long-term impacts of climate variability on the minimum and maximum temperature, relative humidity, and average precipitation during on- and off-season for rice productivity were also analyzed using an autoregressive distributed lag (ARDL) model. The results indicated that climate variability has an overall negative impact on rice productivity. Specifically, minimum temperature and on- and off-season precipitation had major long-term impacts, while higher relative humidity had a pronounced short-term impact on rice yields. The study revealed that short-duration cultivars with higher yields provided greater net savings in irrigation resources. These analyses are critical to guide the development of strategic management plans to mitigate short- and long-term climate effects on overall rice production and for developing and deploying improved rice varieties for sustainable rice production.

“…According to Abdelhalim et al, 2020, the water levels of the groundwater aquifer especially the regional aquifer will be changed as a result of the expected reduction in the surface water and the recharge to these aquifers, due to climate change and the construction of the Grand Ethiopian Renaissance Dam. Aziz et. al., 2019 studied the potential effect of the construction of the GERD on the Nile water in Egypt especially in a pilot area at East delta.…”

Groundwater is considered one of the important sources in Egypt. However, it is expected to face many challenges in the next few decades. The Eastern Nile delta fringes region, the current area of interest, is one of the most highly developed areas in Egypt for more than three decades. Special attention will be given to the existing large reclamation lands (surface water/groundwater) in the high desert lands and low ones which are adjacent and surrounding the Ismailia canal. Under the expected stress of extensive shortage in surface water of the Nile water system, as a result of the construction of GERD, the rapid population and urbanization, a direct impact on the groundwater system in terms of groundwater levels and water budget will be expected. The main research question of the present study is: what is the response of the Nile Delta Aquifer in the south Eastern Nile Delta Fringes in the case of crisis for the sustainability of existing large projects? Visual MODFLOW was used to simulate the existing condition of the irrigation canals and the expected changes under different scenarios of water shortage. The model was simulated and calibrated for the initial hydrogeological conditions throughout the period . The model was tested for scenarios based on the final calibration as an initial condition. Four scenarios were proposed and simulated for the calibrated regional groundwater model at the study area to evaluate and predict the response of the quaternary aquifer during the decrease of surface water levels for 20 years. These scenarios are: 1. Decrease of the surface water levels by 10% against drainage surplus this expression represents the net recharge to the aquifer all the year, 2. Decrease of the surface water levels by 10% against seasonal drainage surplus for six months (summer, winter), 3. Decrease of the surface water levels by 20% against drainage surplus all the year and 4. Decrease of the surface water levels by 20% against seasonal drainage surplus for six months (summer, winter). The results of simulated scenarios showed a change and fluctuation in the groundwater levels, while the maximum value of the change in storage was found in scenario 4.in which this value was decreased by 52.9 % between 2017 and 2037. but in all scenarios, the change in storage of the aquifer still stable and continuously increase, by 36.5% under scenario 2 and 29 % under scenario 4. This volume of storage will be available for pumping by extraction wells in case of surface water reduction.
