This briefing paper published by the Environment Community of Practice (ECoP) revolves around the provision of cash in the aftermath of crisis or during protracted displacement and potential impacts on the environment. The provision of cash can help people access the things they need such as food, shelter or energy. But what if the sources of these goods and services are poorly regulated and have negative impacts on people and the environment? Does the immediacy of providing potentially lifesaving support override broader concerns of local market systems that might be unsustainable or contravene SPHERE and other standards that guide our work? These are questions that are examined in the briefing paper that can be downloaded here.
