IUSS Strategic Plan 2021-2030

The IUSS President's Committee has drafted the “IUSS STRATEGIC PLAN 2021-2030 - The IUSS towards its Centennial and beyond”. Comments from the IUSS Executive Committee and the IUSS Council were considered in the final version which was formally approved by the IUSS Council during its WCSS 2022. To advance the accomplishment of this Strategic Plan through a set of actions that allow the IUSS to fulfill its scientific aspirations, the IUSS also needs to develop an Implementation Plan, supported by some relevant policies guaranteeing IUSS governance. All IUSS officers and Full members are requested to contribute to the implementation of this Strategic Plan.

IUSS Notice of non-discrimination and DEI Policy

The International Union of Soil Sciences (IUSS) supports the Principle of Universality (freedom and responsibility) of Science: the free and responsible practice of science is fundamental to scientific advancement and human and environmental well-being. Such practice, in all its aspects, requires freedom of movement, association, expression and communication for scientists, as well as equitable access to data, information, and other resources for research. It requires responsibility at all levels to carry out and communicate scientific work with integrity, respect, fairness, trustworthiness, and transparency, recognising its benefits and possible harms.

In advocating the free and responsible practice of science, IUSS promotes equitable opportunities for access to science and its benefits, and opposes discrimination on the basis of race, color, ethnicity, national origin, sex (including sexual harassment and sexual violence), sexual orientation, gender identity, religion, age, ancestry, disability, genetic information, military status, or veteran status, in its programs and activities as required by applicable laws and regulations.

Should any acts of discrimination come to your attention, do not hesitate to contact the IUSS Secretariat at iuss@umweltbundesamt.at.

IUSS diversity, equity, and inclusive policy




This scientific book was developed by decision of the Board of Directors of the Bulgarian Soil Science Society. For  development  of this issue were involved  the best scientists  and students from ISSAPP "Nikola Poushkarov", Agricultural University - Plovdiv and University of Forestry-Sofia. This book is based on modern rules, criteria and diagnostics, FAO, European and world standards. The classifications were prepared and discussed at a scientific session held on November 14, 2018 with the scientific community of ISSAPP "N. Poushkarov" and other scientific and academic organizations. The book can be used in the curricula of university and secondary schools with agronomic, forestry, agricultural, economic, biological and environmental characteristics and in the development and use of various scientific, scientific-applied and technological projects at national and international level. The book will be useful for agricultural, forestry and conservation organizations to modernize projects and develop projects for management of agricultural, forest, unprotected  and protected areas, for projects and EIA abroad for ecology and use of the environment.

This book is an important investment in the future for the development of science and practice.

Bulgarian Soil Science Society (BSSS)  was founded in 1942 with the aim to acquaint the general public with soil science, with an emphasis on the importance of soil. This original mission of BSSS is more relevant than ever in the public debate for the conservation of soil resources. TheSociety also will organize various public events and activities related to the protection of our lands, recovery of contaminated soils and sustainable land management. The official BSSS webpage  will provide information about soils in Bulgaria and the problems associated with them.

Other main objectives of BSSS are to promote knowledge and innovative products of the soils science,  to support state policy and institution. For rational use and conservation of soil and land resources, to build up high international prestige of  Bulgarian soil science and scientific community. These objectives are implemented by conducting various creative, scientific and public initiatives - holding of national and international scientific and practical conferences, symposiums , scientific sessions and seminars, meetings with leading scientists, roundtables on important topics, printing and dissemination of scientific literature, publication of biographical essays by prominent scholars, training of young soil scientists.

BSSS is a member of the International Union of Soil Science (IUSS) , constantly maintaining fruitful relations and contacts with soil science organizations and leading scientists from many countries of the world such as EU countries, Russia, China, USA and neighboring  Balkans countries. More than 70 scientists and experts from various institutes and higher education institutions, non-government and government organizations are members and actively participate in ongoing initiatives .

 During 2015 - the International Year of  Soil, BSSS adopted a program to promote the importance of  soil. In May 2015 BSSS and ISSAP “N. Poushkarov” held conference dedicated to the International Year of Soils and the 140-th anniversary from the birth of Nikola Poushkarov - „SOIL AND AGROTECHNOLOGY IN A CHANGING WORLD“. This year a new scientific journal will be created – Bulgarian Journal of Soil Science.
