FEBLES-GONZALEZ, José Manuel et al. Myths, realities and uncertainties on the degradation of red ferralitic soils in Cuba. cultrop [online]. 2020, vol.41, n.3  Epub Sep 01, 2020. ISSN 1819-4087.

Currently there is a global debate on the degradation of soils, their magnitude and agro-environmental impact, on which, long-term experimentation provides qualitative and quantitative criteria regarding their capacity for restoration through rational use and management. In this context, research conducted over the past 30 years confirms that the existence of degradation processes in Red Ferralitic soils in Cuba has a multifactorial nature, dependent on geological - geomorphological conditions, extreme weather events and intensive anthropogenesis. Taking into account these aspects, the present work reviews 10 main visions, which have limited the full recognition of the specific modalities assumed by water erosion and erosive - karst in these regions, which reveal the need to adopt a policy so that its protection ceases to be a myth and becomes a National Security issue. Experience shows that the lack of harmonized methods of surveillance and information transfer is one of the causes that generates uncertainty about the state of its degradation.

Keywords : Uncertainty; degradation; karst region; Red Ferralitic soil.
