As in all Mediterranean countries water scarcity is becoming a serious problem in Lebanon. The increase in populations and the ongoing global climate change will augment water shortages in the forthcoming decades. In most water-scarce countries there is a clear trend that agricultural production shifts from low value crops to high-value cash-crop vegetables and fl owers. Greenhouses play an important role in these transformations, as they allow for controlling the production factors and the effi cient use of land and water resources. Greenhouse horticulture results world-wide in the highest production levels. Although greenhouse production signifi cantly increased in Lebanon, it has not realized its full potentials to contribute to the economic and social development of the country, and to provide employment and income opportunities for both the Lebanese population and the Syrian refugees. This project is aimed at the further development and introduction of greenhouse technology in Lebanon using the “Adaptive Greenhouse” concept, which entails the meticulous design of hardware, software and orgware to the local context, in terms of on-site climatologic conditions, water quantity and quality, soil conditions, energy, socio-economic factors, physical infrastructure, services, human resources, markets, etc.
