Just a small but not insignificant point of clarification here regarding the XPrize ‘feeding the Next Billion’ opening statement (see above): “Food production is projected to grow 70% by 2050…”
This ‘estimate’ comes from a report by the United Nations Food & Agriculture Organization (note: I reported on this back more than 5 years ago on the science/environment blog (planetsave.com). The original news item came from the journal Science (apologies; I am still trying to locate the source blog article).
In point of fact, the report did NOT say that food production was ‘projected to grow’ by 70%…rather, the report stated that global food production NEEDED to grow by 70% by 2050 in order to feed the projected 9+ billion people on earth (by 2050). This estimate was also presented in the context (in my blog article, and in the FAO report) of 25% of the world’s arable land (i.e., the soil) being “degraded” (unsuitable for crops)…thus presenting a serious challenge to growing this additional quantity of food (world wide).
This is an important distinction, and, certainly underscores the need for an XPrize Challenge on this important/vital issue.
