The International Network of Soil Information Institutions (INSII) is composed by nationally mandated institutions and GSP partners developing the Global Soil Information System (GLOSIS).

These institutions are also active members of the Regional Soil Partnerships. INSII members are the main implementing institutions of the Pillar 4 Implementation plan. These institutions have the technical ability to develop and share selected national soil information and data. All institutions, whether sub-national or national, regional or global, can join the INSII network for collecting and distributing information on the status of the soil resource.
