The State of Israel has a very diverse climate. Most of the country is in a semi-arid zone, with distinct short winter (wet) and long summer (dry) seasons, and a low annual rainfall of around 500 mm (an overall multi-annual average). The country can be divided into two climatic regions: (1) the southern arid/semi-arid areas have very low annual precipitation (600 mm). Israel has suffered from a chronic water shortage for years. In recent years, however, the situation has developed into a severe crisis; since 1998, the country has suffered from drought, and the annual rainfall was short of the multi-annual average in most of the years. The agricultural sector has suffered most because of the crisis. Due to the shortage, water allocations to the sector had to be reduced drastically causing a reduction in the agricultural productivity. In spite of the obvious climatic constraints and overall shortage of water, both agriculture and aquaculture are highly developed in Israel. Israeli agriculture depends, to a large extent, on irrigation of crops during the dry summer. To deal with these impediments, different solutions and methods to maximize water use and enable production of fresh edible fish have been developed, including: (i) reservoirs to store rainwater during the wet season, many of which are used for fish culture in integrated farming systems; (ii) large-scale recirculating systems, in which water from outdoor fish ponds, raceways and tanks is passed into sediment ponds to remove the solids; (iii) highly-intensive recirculating systems that incorporate water filtration systems, such as drum filters, biological filters, protein skimmers and oxygen injection systems; and (iv) greenhouse technology was adopted from desert vegetables and flower agriculture and includes environmental control, i.e. humidity, temperature, light and radiation.
