Abstract:
Groundwater is a valuable resource because it is widely used for drinking, and for domestic, agricultural, and industrial purposes. Globally, Saudi Arabia is known to be one of the driest regions with scarce water resources. The shallow groundwater near the major cities in the Kingdom of Saudi Arabia is becoming polluted because of industrial effluent discharge, use of fertilizers in agriculture and domestic sewerage in the region. This review tries to focus on groundwater quality problems due to anthropogenic or geogenic sources in the region of Saudi Arabia. In this paper, we focus on different water-quality variables, for groundwater quality evaluation and aquifer vulnerability assessment due to pollutants/contaminants present in groundwater. The current study gives a holistic understanding of different groundwater quality problems and therefore identifies the gaps of the previous studies and identifies the viewpoints of the future research dimensions. We describe the different groundwater quality problems related to toxicities of the fluoride, nitrate, and heavy metals and radionuclides in Saudi Arabia. A majority of the groundwater pollutants are of natural origin, but there is significant wastewater effluent discharge in the region that is also responsible for contamination of aquifers with heavy metals.

Abstract:
Extension services (ES) play a crucial role in addressing the various needs of organic farmers and little is known about the extension agents’ (EA’s) perceptions of organic agriculture and the role of ES in organic agriculture. This study investigated EA’s perceptions of the role of ES in organic agriculture. Data were collected via a questionnaire, which was sent electronically to all enlisted extension agents in Riyadh Region, Saudi Arabia. In total, 69 extension agents completed the questionnaire, representing a 54% response rate. Overall, extension agents had slightly positive attitudes toward organic farming but were unsure about their role and participation in this. Furthermore, their perceptions of the role of ES in organic agriculture significantly varied according to their age, work experience in organic agriculture, and education level. These findings have implications for the design of future training programs for the professional development of extension agents and will enable planners, policy makers, and related ministries to devise viable and workable policies and plans that truly reflect the concerns and challenges of extension agents and consider the skills of extension agents that need to be improved. This research will also have positive implications for the national organic agriculture policy, as it provides research-based information on the actual players in the farming systems of Saudi Arabia.

Abstract:
Abstract. Saudi Arabia has the world's fifth-largest desert and is the biggest importer of food and agricultural products. Understanding soil microbial communities is key to improving the agricultural potential of the region. Therefore, soil microbial communities of the semiarid region of Abha, known for agriculture, and arid regions of Hafar Al Batin and Muzahmiya were studied using Illumina sequencing. The results show that the microbial communities of the Saudi desert were characterized by the presence of high numbers of Actinobacteria, Proteobacteria, and Firmicutes. In addition to Sahara desert signature phyla like Gemmatimonadetes, biogeochemically important microorganisms like primary producers, nitrogen fixers and ammonia oxidizers were also present. The composition of the microbial community varied greatly among the sites sampled. The highest diversity was found in the rhizospheric soil of Muzahmiya followed by Abha. Firmicutes, Proteobacteria and Actinobacteria were the three main phyla detected in all the samples. Soils from the agricultural region of Abha were significantly different from other samples in containing only 1 % Firmicutes and 3–6 times higher population of Actinobacteria and Bacteroidetes, respectively. The presence of photosynthetic bacteria, ammonia oxidizers, and nitrogen fixers along with bacteria capable of surviving on simple and unlikely carbon sources like dimethylformamide was indicative of their survival strategies under harsh environmental conditions in the arid soil. Functional inference using PICRUSt analysis shows an abundance of genes involved in photosynthesis and nitrogen fixation.

Abstract:
The objective of the study is to measure the defined water qualities of the well waters from Taif regions, KSA. Quality analysis of is needed to provide necessary data regarding the sources of pollution and pointers for health protection. Physiochemical and microbiological qualities of the samples from 11 distinguished wells were fastidiously evaluated. The observed pH (7.5 to 8.2) of the collected samples are lies underneath counseled standards. Distribution of the 15 chemical elements in the samples were determined. Among all the principle elements of soil ‘cations' are higher in the T2 samples like sodium(Na) (531 mg /l), calcium(Ca) (252 mg/l) and lead(Pb) (0.11 mg/l). Almost all the samples are contaminated with potassium (K) and phosphorus (P). The observed concentration are ranged between (0.259 to 9.23 mg/l) and (0.062 to 0.43 mg/l) respectively. The highest concentration of potassium was observed in T3 and T17. Samples from the wells which is nearby agriculture lands are highly contaminated than the other wells. The pathogenic indicators were detected in many samples in that (T1,T17,T23,) as of fecal contamination. Continuous assessment of water quality on the routine basis is needed to maintain the well water quality as well as to eliminate health issues.

Abstract:
The effect of tertiary treated sewage effluents on the plant cover and the physico-chemical properties of the surface soil (environmental characteristics) before and after the Al Rass sewage plant was investigated. The data were illustrated via TWINSPAN and canonical correspondence analysis (CCA). Five sites, 1 km apart, after the discharge point and one site (control site) before the sewage plant were examined. Eleven vegetation characteristics and ten physico-chemical properties of surface soil were studied. The obtained results revealed that discharging of treated sewage effluents altered quantitatively and qualitatively the pattern of species dominance and the physico-chemical properties of the soil. Soil electrical conductivity (EC), total dissolved solids (TDS), organic matters (OM), soluble cations, and soluble anions showed increased values compared to the control (resulting in salination), whereas soil pH decreased as a result of sewage disposal. It was also noticed that the physico-chemical values of EC, TDS, Ca<sup>++</sup>, Mg<sup>++</sup>, Na<sup>+</sup>, Cl<sup>–</sup> after the sewage plant were higher than the permissible limits for agriculture recommended by FAO, whereas K<sup>+</sup> and HCO<sub>3</sub><sup>–</sup> were within the recommended values. The dominance of Suaeda vermiculata Forssk. ex J.F.Jmel. after the sewage plant and its absolute absence before the sewage plant may be used as an environmental bioindicator of pollution.

Abstract:
Limited water supplies available in many countries of the Near East has led to a growing interest in the rational use of this increasingly important resource. Because wastewater irrigation ensures the reuse of resources and achieves better treatment of wastewater, plans have recently been formulated for large-scale use of this non-conventional source of water. Consequently, in several countries of the Near East Region, wastewater reuse in agriculture is an accomplished and accepted fact, with a high degree of social and political commitment. Intensive and direct reuse is being practised in Kuwait, Saudi Arabia, Libya, the United Arab Emirates and Tunisia. Direct, but unsupervised reuse is iking practised in Yemen Arab Republic, Morocco and Syria. All forms of wastewater reuse is practised in Egypt. Indirect and direct restricted reuse is practised in Jordan. However, given the health and environmental hazards associated with reuse of wastewater, the formalization of wastewater treatment and reuse in all countries is urgent. Furthermore, in most countries poor coordination amongst the different agencies concerned with water supply, wastewater treatment, irrigation, public health and the environment is a key constraint for further wastewater reuse.

Abstract:
This dissertation presents a case study of agricultural land use patterns and marketing aspects in the Taif region of Saudi Arabia. This area is one of importance to the overall agricultural future of Saudi Arabia, being a major producer of fruits, vegetables and dates in the Kingdom. In recent years, increases in personal income associated with oil production in the Kingdom have created significant changes in the types of crops grown as well as the way of life of the small farmer. These changes include the following: (1) Because better paying jobs and an enhanced lifestyle are luring farmers to the large urban areas, fewer workers are available for labor on the farms. (2) Large government subsidies have created a situation where the small farmer finds it no longer profitable to grow cereal crops as he traditionally did. (3) A lack of adequate refrigerated trucks and an increase in salinity in groundwater has caused farmers near the market centers of Makkah and Jeddah to cut fruit trees and replant with vegetables that can withstand more saline water and can be transported to the nearby markets more easily than those framers living in the farther areas of the region. What the author concludes is that increased attention to the problems of the small farmer in the region is necessary so that food supplies will be maintained to feed a growing population and so that self-sufficiency can be achieved. Additional support by the government in the way of subsidies and loans and more programs to educate farmers in marketing techniques and improved farm methods and management must be developed. And finally, the farmers should work together, sharing information and resources for the common good of all small farmers in the region.

Abstract:
The coastal plain called Tihama forms the principal agricultural zone which makes Jizan one of the main agricultural regions in the Arabian Peninsula. The Saudi government has keenly appreciated this wealth of Jizan and explored developing its potential in the mid-1940's. However, the pace of agricultural development in Jizan has been very slow, and an actual decline has been registered in traditional agriculture. This stagnation is caused by constraints imposed by unfavorable "institutional arrangements," i.e., those incentives and disincentives which are the product of the political economy of the country. Problems facing agricultural development in Jizan are explained within the context of the country's institutional arrangements. The contribution of the spatial structure of Jizan and the lack of sufficient impact by the urban/industrial complex of this region are detailed as causes for this problem. To its credit, the Saudi government imposes neither taxes nor restrictive economic policies on agriculturalists. Moreover, general financial support for farmers and investment in public projects are benefiting the agricultural sector of Jizan. These factors led to the evolution of the modern tubewell farming system in Jizan which began in 1961/62. Existing incentives are overshadowed by disincentives which are hampering agricultural and general regional development in Jizan. Unfavorable farm policy, such as subsidization of foodstuff imports, and out-migration due to unequal regional growth in the country, accelerated a process of agricultural decline in Jizan. Until 1962 this decline was not arrested by government investment due to the lack of funding. Ironically, the rise in revenue from oil exports seems to have undermined the need for agricultural development in Jizan. Recent government efforts to develop the country's agricultural sector yielded a farm policy which is unfavorable to Jizan. Projects which are vital for this region's agriculture have been implemented only recently, or as in the case of many irrigation projects, have not yet been built. In the 1980's Jizan, which had 14% of the country's agricultural land, received only about 1% of the value of loans provided by the government to farmers. As a result, Jizan remains a region with substantial, but still unrealized potential.

Abstract:
Pastoral nomadism in arid and semiarid regions has evolved over many centuries as a rational response to uncertain climatic conditions and fragile ecosystems. Nomads are the main inhabitants of the bast area of marginal rangeland in Saudi Arabia. However, in the past few decades, modernization, in the form of improved transportation and access to water, combined with government subsidy of supplemental barley to the nomads of regions such as At-Taisyiah in the northern part of Saudi Arabia have provided the nomadic tribes with a buffer against uncertain climatic conditions and against the consequences of increasingly aggressive grazing of the range. In this study, an integrated approach is adopted to assess the impact of modernization and government intervention on the nomads and on the health of rangelands in At-Taisyiah. The approach consisted of interview with nomads in the region, a socio economic study of the region's nomadic lifestyle, analyses of several range capability assessment studies, and utilization of stochastic simulation models. Three major areas were identified in need of major improvements. These are the nomads' perception of range land resources, use of rangeland, and government policies towards nomads and rangeland. Improvement in these areas will play a major role in slowing the acceleration of desertification of marginal range lands in Saudi Arabia. comparison of Monte-Carlo simulations of four different grazing intensity scenarios and 12 different levels of government subsidies confirmed that lower grazing intensities provide the only means for sustainable utilization and for the combating of desertification of the rangelands in At-Taisyiah region.
