Saudi Arabia (SA) faces a water shortage, and it further challenges sustainable agriculture, industrial development and the well-being of people. SA uses more than 80% of its water resources for agricultural purposes. Groundwater extractions account for most of this demand, which is not sustainable. Hence, this study aims to analyze water management practices used in SA to propose viable and workable solutions to achieve sustainable management of scarce water resources. This study is based on a critical evaluation of information available on the water sector in SA. About 89% of the water demand in the Kingdom is non-sustainably met through over-pumping from groundwater resources and 9.3% by energy-intensive desalination. SA invested in dams and developed rainwater harvesting to enhance surface water availability and increase the recharge capacity of renewable aquifers. As there is a huge demand–supply gap, water demand management tools are the viable solutions leading to sustainability compared to supply enhancement that is capital intensive. A national agricultural policy, together with a water policy, can make agricultural systems more input efficient with higher productivity. Region-specific sustainable water resources management plans need to be implemented to match the demand–supply gap. Conjunctive water uses utilizing and prioritizing different water sources viz. harvested rainwater, treated wastewater, desalinized water, and groundwater, is vital in sustainable water resources management. In addition, climate change has exerted pressure on the available water resources and water uses as well as users, leading to adaptation for measures that are more sustainable in terms of water management. The most pressing problem SA faces in water resources management is the depletion and degradation of surface and subsurface water sources. SA has to implement many technological and legislative changes in addition to service management, conservation measures, paying a reasonable and justifiable price for water, and strengthening state agencies that will make water resources management in SA sustainable.

Agricultural foreign direct investment (AFDI) contributes to the long-term growth of developing countries. Sudan has rich agricultural resources with great potential for AFDI. However, so far, Sudan has not exploited this potential to attract investors from other countries, having less of a competitive advantage in agricultural production owing to local and international problems. In this study, we examined the effects of foreign investments of Gulf Cooperation Council (GCC) countries on agricultural exports in Sudan, in addition to other economic factors during 1990–2016 using the two-stage least squares (2SLS) model. The results showed that the investments of GCC countries in Sudan’s agricultural sector boosted agricultural exports. The exchange rate was found to be a key determinant factor of GCC countries deciding to invest in Sudan. We recommend that the Central Bank of Sudan encourage policies to stabilize the exchange rate to attract more agricultural investment from GCC countries.

Date production farms account for 10% of total income in the agricultural sector. Although Saudi exports of dates reach many countries, they are still of lower quantity compared to the size of their production. This study investigates the possibility of expanding external marketing of date exports by increasing the marketing efficiency of the existing market, which is expected to lead to increased returns. Therefore, this research uses the gravity model to identify the most critical factors affecting Saudi date exports to Middle Eastern countries. The results indicated the positivity of the per capita GDP in Saudi Arabia, the common border in influencing the increase in date exports, and the opposite effect of membership in the Gulf Cooperation Organization (GCC). In estimating the potential and expected trade capabilities with the Middle Eastern countries, the study results show that the actual value of date exports to the countries of the Middle East represents about 83.37% of its expected potential date trade, and it is possible to increase the export value by 16.63%, or USD 12.75 million. The study provides recommendations to improve date trade further.

The goal of this study was to look at the economic relationship between energy, water use, and plant and animal food production in Saudi Arabia from 1995 to 2020. The results showed that about 55.5%, 82.4%, and 2.5% of changes in the index of plant and animal food production were related to changes in the consumption of water, electricity, and diesel, respectively, using an econometric analysis and the partial correlation coefficient of the second order. The proposed model demonstrated that a 10% change in predicted water, power, or fuel consumption resulted in a 1.97%, 2.78%, and 0.73% change in the index of plant and animal food production, respectively. In light of the Green Middle East Initiative, which intended to minimize carbon emissions, and Saudi agriculture’s goal of rationalizing water use, the country’s total consumption does not exceed 8 billion m³ of renewable groundwater. This is intended to reduce the use of fuel and increase the use of electricity in the agricultural sector. This rationalizing water consumption, reducing diesel consumption, and expanding electricity consumption affects the production of plant and animal food. In light of the strong interdependence between water, energy, and food production, the agricultural policy has become necessary to increase the amount supplied or available for water to be used in food production, in addition to expanding the production of clean energy and its use in the agricultural sector.

The goal of this study was to determine how the loss of dates affected food security in Saudi Arabia from 2000 to 2021. The researchers achieved this by using food security indicators, economic equations to quantify agricultural resource losses, and econometric analyses to develop a partial adjustment model. The results show that dates are considered a self-sufficient crop as well as an export crop, as the state resorts to exporting the surplus instead of storing it for local consumption. During the study period, there was an increase in the period of sufficiency in date production for local consumption and the period of coverage of imports for local consumption. In 2000, the volume of dates lost increased by approximately 131.22%. The total loss of land and water resources reached 31,918.4 hectares and 324.759 million cubic meters, respectively. The value of the partial adjustment coefficient (λ) indicates that about 81.1% of the imbalance in the equilibrium between the actual and equilibrium levels is adjusted within one year. Loss is considered one of the most important factors that determine food security for dates, in addition to the total value of loans financed to date factories, the total population, and the level of technological progress in the marketing and storage of dates. It was found that a change of 10% in these variables leads to a change in food security for dates of (−2.37%), 0.07, (−15.33%), and 0.58%, respectively, and the adjusted coefficient of determination was estimated at 0.93. This study recommends the following: (1) expanding the use of modern technologies for date post-harvest transportation and storage, and (2) increasing support and loans allocated to date factories to increase warehouses for cooling and storage to accommodate the increase in production and surplus consumption.
