An Early Warning System (EWS) is a set of coordinated procedures through which information on foreseeable hazards is collected and processed to warn of the possible occurrence of a natural phenomenon that could cause disasters. These systems are acquiring more importance in view of increased climate variability and the ability to implement them has become fundamental for improving capacity to adapt to climate change.

Climate insurance against crop loss is common in developed country agriculture where farmers insure against crop loss due to extreme climatic events such as flooding or drought. Typically payments are made on the basis of the crop loss from on-farm inspections. However the on-farm inspections can be expensive and potentially subjective. Table 1 gives a summary of different kinds of agricultural climate insurance schemes.

Systems of pressurised irrigation, sprinkler or drip, can improve water efficiency and contribute substantially to improved food production.

Drip irrigation is based on the constant application of a specific and focused quantity of water to soil crops.  The system uses pipes, valves and small drippers or emitters transporting water from the sources (i.e. wells, tanks and or reservoirs) to the root area and applying it under particular quantity and pressure specifications. The system should maintain adequate levels of soil moisture in the rooting areas, fostering the best use of available nutrients and a suitable environment for healthy plant roots systems.

Fogs have the potential to provide an alternative source of fresh water in dry regions and can be harvested through the use of simple and low-cost collection systems. Captured water can then be used for agricultural irrigation and domestic use. Research suggests that fog collectors work best in locations with frequent fog periods, such as coastal areas where water can be harvested as fog moves inland driven by the wind.
