A comprehensive, practical text which covers a diverse range of hydroponic and protected cropping techniques, systems, greenhouse types and environments. It also details the use of indoor plant factories, vertical systems, organic hydroponics and aquaponics.

Crop Protection in Medieval Agriculture available in PDF, EPUB and Kindle. Mediterranean and West European pre-modern agriculture (agriculture before 1600) was by necessity ‘organic agriculture’. Crop protection is part and parcel of this agriculture, with weed control in the forefront. Crop protection is embedded in the medieval agronomy text books but specialised sections do occur. Weeds, insects and diseases are described but identification in modern terms is not easy. The pre-modern ‘Crop Portfolio’ is well filled, certainly in the Mediterranean area. The medieval ‘Pest Portfolio’ differs from the modern one because agriculture then was a Low External Input Agriculture, and because the proportion of cultivated to non-cultivated land was drastically lower than today. The pre-modern ‘Control Portfolio’ is surprisingly rich, both in preventive and interventive measures. Prevention was by risk management, intensive tillage, and careful storage. Intervention was mechanical and chemical. Chemical intervention used natural substances such as sulphur, pitch, and ‘botanicals’. Some fifty plant species are mentioned in a crop protection context. Though application methods look rather modern they are typically low-tech. Among them are seed disinfection, spraying, dusting, fumigation, grease banding, wound care, and hand-picking but also scarification, now outdated. The reality of pest outbreaks and other damages is explored as to frequency, intensity, and extent. Information on the practical use of the recommended treatments is scanty. If applied, their effectiveness remains enigmatic. Three medieval agronomists are at the heart of this book, but historical developments in crop protection from early Punic, Greek, and Roman authors to the first modern author are outlined. The readership of these writers was the privileged class of landowners but hints pointing to the exchange of ideas between them and the common peasant were found. Consideration is given to the pre-modern reasoning in matters of crop protection. Comparison of pre-modern crop protection and its counterpart in modern organic agriculture is difficult because of drastic changes in the relation between crop areas and non-crop areas, and because of the great difference in yield levels then and now, with several associated differences.

Unlocking the potential of protected agriculture in the countries of the Gulf Cooperation Council - Saving water and improving nutrition available in PDF, EPUB and Kindle. The Gulf Cooperation Council (GCC) is a political and economic union of Arab states, namely Bahrain, Kuwait, Oman, Qatar, Saudi Arabia and the Unites Arab Emirates. The GCC was formed in 1981 to strengthen the members’ economic, social and political ties by harmonizing regulations in various fields including economy, finance, trade and customs. The region extends over a territory of 2 673 108 km2 and is home to about 50 million people. The common denominators of the GCC countries are limited natural fertile land, scarce water resources and harsh climate. Depending on the country, the agriculture sector may use as much as 75 percent of the national available water resources. This has enormous environmental costs and significantly affects the sustainability of overall development in the Arabian Peninsula.According to Al-Rashed and Sherif (2000), the lack of renewable water resources is one of the critical constraints to sustainable development in the GCC countries. Rainfall in the Arabian Peninsula is scarce and infrequent. Over-exploitation of fossil groundwater resources, mostly to meet irrigation demands and create greenery lands, has already affected the productivity of aquifers, both quantitatively and qualitatively, despite the fact that much of the freshwater demand in the GCC countries is already covered using desalinated water. Reducing water consumption and increasing water efficiency are essential to enhancing agriculture and moving towards increased self-sufficiency with the production of high-quality, safe and diversified foods in the GCC countries. Exploiting the full potential of protected agriculture should save significant amounts of water, which can be used not only for agriculture but for other needs as well.
