Agriculture Market Information Systems (AMISs) seek to collect, process and disseminate information on the situation and the dynamics of agricultural markets. In the 80s and the 90s, an unprecedented number of AMISs were created in developing countries, mainly spurred on by the public sector. Developed tools to support the liberalization of agricultural markets, AMISs sought to fulfill two linked objectives: improving public policies through increased awareness of market realities and increasing market transparency in order to induce a fair and efficient allocation of resources. AMISs were more specifically developed for products directly linked to food security (such as cereals).
