The series of the ITPS soil letters aim to provide to the general public concise and clear information on one topic linked to the work and activities led by the Intergovernmental Technical Panel on Soils (ITPS). The ITPS was established at the first Plenary Assembly of the Global Soil Partnership held at FAO Headquarters in 2013.

The ITPS is composed of 27 top soil experts representing all the regions of the world. Its main function is to provide scientific and technical advice and guidance on global soil issues to the Global Soil Partnership primarily and to specific requests submitted by global or regional institutions. The ITPS advocates for addressing sustainable soil management in the different sustainable development agenda.
