Environmental conflict belongs to a larger set of social interactions and thus part of a complex process. Moreover, these relations are dynamic in nature and thus involve considerable feedback mechanisms. Environment can be a cause of war (scarcity or resource driven), occurring both inside and outside of sovereign state boundaries, a strategy for waging war against a population, a battlefield tactic, or a source of funding for conflict forces. Moreover, more than one of these factors can be in play in a conflict over time.
