A UK-based development programme has shown that a wide range of urban and agricultural wastes can be recycled as fertilisers, to the exclusion of manufactured mineral fertilisers, to produce sustainable, high-yielding agriculture and increase bio-diversity and populations. The programme has shown how that technology can be used to develop sustainable worldwide agriculture and dramatically reduce irrigation requirements including in arid and desert soils. This, in turn, closes the loop on recycling potentially significant amounts of global Carbon dioxide by changing the hydrological cycle, and increasing the global soil Carbon sink and releasing Oxygen back to atmosphere.
