Areas of Bács-Kiskun and Csongrád County, according to its orographic-climatic characteristics, have a frequent events of storm with severe hail that can cause enormous damages, primarily in agriculture. Adjacent territory of Vojvodina-Backa in the Republic of Serbia has a good hail suppression system based on the radar measurements of convective clouds and cloud seeding by reagents on the basis of silver-iodide. This kind of modification of these dangerous meteorological phenomena in the Republic of Serbia is carried out over 40 years with the fact that there is an excellent team of experts, clearly defined methodology for hail suppression and modern technical support. Also, there is a mutual great interest to build the similar system in Bacs-Kiskun and Csongrád County and rich the maximum of efficiency, especially in the border area between two of our states, because the clouds have no borders in its transfer, so should not exist an interruption zone in their seeding. Without cooperation and a joint system the borderline region can not be protected against hail. Establishing a hail suppression system in Bacs-Kiskun and Csongrád Counties large effects can be expected on reducing damages caused by hail in Backa, and vice versa, because it will not happen to have large, well developed clouds with large hailstones that can simply hand over their "cargo" crossing the border. The interest of farmers in both sides of the border, and therefore the interest of states, the experience and knowledge achieved in Republic of Serbia is the guarantee that this joint project will be effective. Overall objective: Damage prevention - to decrease damage caused by hails. Specific objective: To complete a feasibility study about joint hail suppression system; To inform, the people about the prevention methods, To start the harmonisation of the regulation concerning the operation of hail suppression system in the borderline. Achievements: Areas of Bács-Kiskun County and Csongrád Country are frequently hit by storms and severe hailstorms, which cause enormous damage, especially to agriculture. Vojvodina has a good hail suppression system based on the radar measurements of convective clouds and silver-iodide-based reagent cloud seeding. This kind of modification of these dangerous meteorological phenomena in the Republic of Serbia has been carried out for over 40 years and there is an excellent team of experts, a clearly defined methodology for hail suppression and modern technical support. There was also large mutual interest in building a similar system in Bács-Kiskun and Csongrád counties and reaching maximum efficiency, especially in the border area as clouds know no borders and there should be no interruption cloud seeding zone. Thus cross-border cooperation is essential for protecting crops.As part of the project, the partners carried out a feasibility study into a joint hail suppression system, informed people about prevention methods and began harmonising regulations concerning the operation of the hail suppression system in the border area. In addition to knowledge transfer, valuable hands-on experience in hail protection practices was gained. The project was not only a great opportunity to increase the partner organisations’ institutional and professional capacities, it also initialised preparatory work for introducing harmonized hail suppression system in the border regions of two countries. By combining and complementing expertise, harmonizing practices, policies and regulatory framework, the project partners started the struggle to minimize the destructive consequences of one of the unpredictable forces of nature - hail.
