Abstract
Land as an open system is susceptible to any change in the environment, which makes it necessary to use it in a sustainable way, ensuring its availability for future generations, not only in terms of existence but also in terms of quality and productivity. This is how the concept of Land Degradation Neutrality (LDN) was born in 2012.The present work is developed based on this new concept with the objective of adjusting/updating the method for determining LDN proposed by Orr et al, (2017) to karstic environments. Based on a 1990 baseline compared to the year 2019 in the San José polje, Cuba, plus the adjustments introduced to the method, it shows that the LDN in karstic regions depends mainly on two indicators: edaphic and geological-geomorphological. The edaphic indicators, in general, show a tendency to recovery: increase of forest use (+27%) and increase of SOC content (+7105 t ha−1), being the main cause of this rehabilitation, the economic crisis that Cuba is going through and not totally an agro-environmental awareness.On the other hand, it was determined that the greatest challenge for the progress of agriculture in the polje is due to the geological-geomorphological conditions resulting from the unidirectional and irreversible advance of karst morphogenesis; that with the increase of SOC as a result of the change of paradigm from conventional to organic agriculture can accelerate the dissolution of CaCO3.
