"... land degradation has now become a major threat to the sustainability of
world food supply. This loss arises from soil erosion, salinization,
waterlogging, and urbanization with its associated highway and road
construction. Nutrient depletion, overcultivation, overgrazing,
acidification, and soil compaction contribute as well. Many of these
processes are caused or are aggravated by poor agricultural management
practices. Taken together or in various combinations, these factors decrease
the productivity of the soil and substantially reduce annual crop yields
(30-32), and, more important, will reduce crop productivity for the long term
(33)."

What they fail to address is the ability of "regenerative farming" to deal
with every one of the problems.
