In attempting to assess the health of the myriad global agro-ecological zones – those regions of the planet that translate into the daily kilocalories of human consumers, as well as critical biodiversity that enables our species, and all species, to survive – numerous, often contradictory data sets have all intersected on several hazy fronts that give little comfort to those seeking to forecast predictable resolution to many of the most pressing environmental crises.
The areas of uncertainty include: 1) reliable short-, mid-, and long-term demographic projections; 2) the escalating severity of climate change and hence, the degree of precipitation affecting every aspect of water resources, irrigation, soil moisture and subsequent cultivation practices, nutrient turnover rates, runoff, flooding, extreme weather events, humidity vital to the life of invertebrates, pollination and every biome; 3) the degree to which biodiversity is rapidly disappearing; 4) the capitalization factors that will either ameliorate or further disintegrate agricultural stability from region to region across the globe; 5) the additional component (stressor, or de-stressor) of genetically modified food and other organisms.
