At the same time, awareness about damage created by intensive use of inorganic fertilizers and pesticides, degraded soils and reduced biodiversity is leading more people to push for an alternative path towards achieving global food security. The twin phenomena of climate change and variability are further complicating the outlook, especially because they have a strong negative impact on the world’s arid and semi-arid lands. Experts at the United Nations long foresaw the threat posed by desertification and decided to focus the attention of the global community on it when the UN declared 2010 - 2020 the Decade for Deserts and the fight against Desertification (UNDDD).
