Adapting to climate change with greenhouse technology
Greenhouse vegetable production in temperate regions is associated with high energy consumption, especially in winter. The use of fossil fuels is the main contributor to global warming. Climate-change-related problems such as heat waves and lower summer precipitation, hence water availability, require strategies of increased resource-use efficiency. Recently, a number of energy-saving technologies and concepts have been put into practice that can be useful tools in the process of adaptation. The closed and semi-closed concepts, their technical setup, and their advantages will be described, along with other technical devices. The possibility to maintain higher CO2 concentrations, and reduced entry possibilities for insect pests, are among the beneficial effects of these new concepts. Facing increasing environmental awareness, we will review alternative energy sources such as heating with wood pellets and describe their utility in avoiding fossil fuels. With innovative usage of thermal screens, and new covering materials, energy losses to the outside can be reduced to a large extent. The aim of this review is to show how these systems can be used to mitigate potential adverse effects of climate change while producing vegetables of higher quality more efficiently, with more sustainable use of resources.
