“…However, modern greenhouse farming with soilless cultivation techniques that allow all-year-round crop production, such as hydroponics and aquaponics, have been used recently to overcome all the above limitations and considerably boost domestic food production [25][26][27][28][89][90][91]. Furthermore, these techniques are applicable to urban food production practices that inherently overcome the limitation and competition from urban land-take and the need for ecological conservation and habitat restoration (rewilding).…”

“…It is imperative that the greenhouse design and technical equipment used should be suitable for the Qatari climate as standard methods and technologies used in other regions like Europe and the USA cannot be transferred to the Middle East due to the different climate control strategies and input availability [90]. According to researchers, to achieve an optimal thermal performance of greenhouses operating in hot and arid climates, the greenhouse should be oriented East to West and have an aspect ratio of 1:3, which will allow a lower temperature distribution along 80% of its length.…”

Agricultural Production in Qatar’s Hot Arid Climate

Agriculture has played an essential role in the provision of food and has been a major factor in overall economic development for societies around the world for millennia. In the past, agriculture in hot, arid countries like Qatar faced many challenges, the primary one being a dearth of water for irrigation. Historically this severely limited Qatar’s economic development, which was based largely on resource exploitation, pearl fishing, and only more recently, on the exploitation of its oil and gas reserves which subsequently has led to Qatar’s great wealth. This paper gives an overview of the recent evolution of Qatar’s agricultural sector and investigates future trends that tackle the challenges of its hot arid climate and the limited availability of agricultural resources. Specifically, the review analyses Qatar’s potential to develop a national food security strategy based on a significant expansion of food production in the country. We review recent policy actions implemented to address challenges in the food supply chain caused by a 3.5-year blockade imposed by the adjacent Arab Gulf States, discussing the renewed interest in the potential that an enhanced agricultural sector must provide some aspects of food security and the implications for policymakers that would logically ensue.

“…Namely, the use of Treated Sewage Effluent (TSE) and recycled water for irrigation purposes as well as the use of renewable energies like solar, wind, hydro and geothermal, respectively, in combination with innovative resourcesaving technologies and greenhouse designs adapted to the local conditions, could contribute to lower carbon emissions and save the groundwater resources of Qatar. Practices and standards from other regions such as Europe and America cannot always be applied in hot arid countries like Qatar due to climatic differences which affect energy efficiency and consequently the operation cost (Alkhalidi et al 2020). Pakari and Ghani (Pakari and Ghani 2019) have proposed a new greenhouse design that limits the available solar radiation thus reducing the high cooling demand during the hot season in subtropical countries like Qatar.…”

Greenhouse farming is essential in increasing domestic crop production in countries with limited resources and a harsh climate like Qatar. Smart greenhouse development is even more important to overcome these limitations and achieve high levels of food security. While the main aim of greenhouses is to offer an appropriate environment for high-yield production while protecting crops from adverse climate conditions, smart greenhouses provide precise regulation and control of the microclimate variables by utilizing the latest control techniques, advanced metering and communication infrastructures, and smart management systems thus providing the optimal environment for crop development. However, due to the development of information technology, greenhouses are undergoing a big transformation. In fact, the new generation of greenhouses has gone from simple constructions to sophisticated factories that drive agricultural production at the minimum possible cost. The main objective of this paper is to present a comprehensive understanding framework of the actual greenhouse development in Qatar, so as to be able to support the transition to sustainable precision agriculture. Qatar’s greenhouse market is a dynamic sector, and it is expected to mark double-digit growth by 2025. Thus, this study may offer effective supporting information to decision and policy makers, professionals, and end-users in introducing new technologies and taking advantage of monitoring techniques, artificial intelligence, and communication infrastructure in the agriculture sector by adopting smart greenhouses, consequently enhancing the Food-Energy-Water Nexus resilience and sustainable development. Furthermore, an analysis of the actual agriculture situation in Qatar is provided by examining its potential development regarding the existing drivers and barriers. Finally, the study presents the policy measures already implemented in Qatar and analyses the future development of the local greenhouse sector in terms of sustainability and resource-saving perspective and its penetration into Qatar’s economy.
