Natural hazard services include a wide range of activities, many of which are allied with public safety, but can also be taken to include natural resource management, land-use planning, and other related activities. These activities are considered to be part of emergency management, and have come to be seen as a public sector responsibility even though they are often carried out by contractors. They take place across all of the phases of the emergency management cycle: response, recovery, mitigation, and preparedness. The prevalence of private sector utilization is such that many services, such as hazard mitigation planning, grants administration, and various components of recovery, can be argued to be largely privatized due to the extent of market penetration and control from the private sector, including in the creation of policy and its implementation. However, there are unique challenges that arise when private-sector provision of services, and not just products, is utilized. Partnerships and other collaborative models are utilized frequently, including not just private sector firms, but also non-profit organizations, academic institutions, community organizations, and other groups to help overcome these challenges.
