Payments to the agricultural sector are designated to decrease gradually. One of the consequences of such a process will be a reduction in the number of farms and thereby in the defence of territory. The expansion of areas with hydro geological problems is a global matter. During the 2011 the damage caused by disasters around the world cost 380 BILIONS of USD. For the future, it is possible to suppose an increase in extreme events and disasters of hydro geological nature, also because of a reduction in territory protection by agriculture. The objective of this study is to propose an instrument to involve farmers in territory management, but before that disasters happen. We are looking for an ex-ante solution. In the paper, we propose a potential model, that of Territorial Management Contracts (TMC).
