Abstract

Tla lahko zelo poenostavljeno razumemo kot preperel in spremenjen površinski sloj Zemljine skorje. Je zmes zdrobljenih kamnin in organskih snov in omogoča pridelavo (hrane, krme industrijskih, energetskih, zdravilnih in drugih rastlin), filtrira vodo, transformira hranila ter nevtralizira in razgrajuje onesnaževala. Degradirana tla imajo poslabšano sposobnost sekvestracije ogljikovega dioksida, zato prihaja do večjih izpustov CO2 v ozračje. V degradiranih tleh je močno zmanjšana tudi biotska raznovrstnost. Tla lahko neposredno povežemo z več globalnimi varnostnimi izzivi, saj so ključni člen pri zagotavljanju prehranske, vodne in energetske varnosti. Ker so tla dom največjega števila različnih organizmov so izjemnega pomena pri varstvu biotske raznovrstnosti. Vplivajo na klimatske spremembe in pogostost nekaterih naravnih nesreč (plazovi, suše, poplave). So zelo pomemben dejavnik zagotavljanja in ohranjanja zdravja ljudi in živali, saj sta od tal odvisni količina in kakovost hrane. Tla so lahko vir patogenov in drugih zdravju škodljivih snovi. So tudi osnova za izdelavo nekaterih zdravil in drugih koristnih aktivnih snovi, ki se uporabljajo tudi v kozmetični industriji . So eden izmed dejavnikov, ki lahko potencira nevarnost oboroženih konfliktov in vpliva na migracijske tokove na nacionalni in mednarodni ravni. Z vidika varnosti lahko pojem »Varnost tal« opredelimo s pomočjo petih dimenzij. To so sposobnost, trenutno stanje, vrednost, povezljivost in zakonsko varstvo.

Secondary title:	Soil, Soil Security and Global Security Challenges
Secondary abstract:	Simplified soil could be defined as degraded and modified surface layer of the Earth's crust, comprised of a mixture of crushed rocks and organic matter. It is enabling production of food, forage as well as industrial, energetic, medicinal and other plants. Soils are filtering water, transforming nutrients, and neutralising and degrading pollutants. The soil, once degraded, cannot sequester carbon dioxide in the same extent as before, thus generating higher releases of CO2 into the atmosphere. Moreover, biodiversity of degraded soilis severely deteriorated. Soils can be directly linked to several global security challenges as they are crucial for ensuring food, water and energy security. Since soils are home to largest number of living organisms they are of paramount importance in protecting global biodiversity. Soil status can affect climate change and frequency of some natural disasters (avalanches, droughts, floods). They are enabling and maintaining human and animal health, since food quality (linked to nutrient deficiencies) is highly dependent on soil status. Moreover soils are the origin of many medicines and cosmetic products but are also source of pathogens and other harmful substances. Soils are a factor that can intensify the risk of armed conflict and influence migrations on national and international level. From security point of view “Soil Security” could be defined with five dimensions: Capability, Condition, Capital, Conectivity and Codification.
