Below the threshold, a country's cereal import is strongly dependent on the renew able water resources. However, in the literature the choice of the gold catalyst often seems to be random and so far the strategic approach to the optimization with respect to the ligand and counter anion of the catalyst is inadequate, if involved at all.

In contrast, per capita cereal import remained mostly unchanged in the countries with water resources above the threshold, suggesting no significant relationship between changes in their per capita water resources and the volume of cereal import.

However, as the availability of additional water supply and the number of suitable sites for water project construction decrease and the competition for water from other sectors escalates, the scope of bringing more water into irrigation will be marginal in most of water-scarce countries (, Desalination of seawater has been used in some oil-rich countries, notably Saudi Arabia, to alleviate water scarcity.

Wenxin Liu, Minjuan Zhao, Wei Hu, Yu Cai. However, in developing countries, such a practice has often been carried out using untreated or not properly treated wastewater, causing a serious health concern and soil pollution. The development of irrigation facilities, the availability of inorganic fertilizers, and benign government policies have all facilitated the adoption of green-revolution technology. Many countries that are likely to fall below the water resources threshold in the coming years are poor and hence are unable to afford the purchase of cereals (Table 2).

Cereal production in Saudi Arabia increased from barely 0.3 million ton in the early 1980s to a peak of over 5 million ton in the early 1990s. This is to reduce the effect of specific local conditions of small countries on the analysis of the general relationship between water deficit and cereal import. Reviewers, Librarians A Monte Carlo analysis suggests that the model results are insensitive to moderate variations in the cutoff value of 5000 m3/capita. The production has dropped in the late 1990s and stood at around 2.6 million ton (, The inclusion of additional variables in models 2 and 3 led to shifts in parameter, Hence, the model simulations demonstrate that a water resources threshold can be defined. Between the first and the last investigation periods, there is a significant decrease in per capita renewable water resources for all the countries considered as the result of population growth (all arrows point to the left in Figure 1).

In view of the high cost of wastewater treatment and the health risks involved, using wastewater for irrigation at the moment may only be suitable in limited areas. Virtual water implies indirect water use: water-poor countries importing food rather than attempting self-sufficiency and thereby keeping their real water resources for economically more beneficial uses. Severe stresses are being generated by increasing demand for competing water uses, above all between agriculture and urban needs. Water deficit-induced food insecurity and starvation could intensify because cereal import may not be affordable for these countries. On the basis of this threshold, we project the potential scale of water deficit-induced cereal import in the next 30 yr and address some of the implications for the world food security and international trade.

Egypt's needs a breakthrough in research and development for irrigation using renewable energy (mainly solar and wind) by a desalination process. Cereal import has played a crucial role in compensating local water deficit. This situation gives rise to a consideration of other factors in the model. on Egypt's present and future water resources.
