It gives a broader overview of what is to be expected in climate patterns, and such knowledge is important in formulating adaptation planning for crop ranges that are drought-resilient and in planning for suitable irrigation projects.
The approximate land area required per metric ton of crop ranges from 0.01 ha (sugarcane for Australia, Brazil, Chad, China, Egypt, India, Mexico, Sudan, and USA) to 4.38 ha (millet in Sudan) (Table 9).
The EFSA Panel argues that the "dose distance relationship, derived by Hofmann et al. [2] from regression on logarithmic scales, should have been based on their data from samplers placed at distances from the nearest maize crop ranging from 0.8 m to 4.4 km only.
Its crops range from bananas and pineapples to coffee, maize and livestock; some 40% of the country's food is produced here by 20% of its population.
Mr. Avedon's taxonomies of the human spirit, feats of high contrast and ingenious cropping, range from a civil rights era portrait of a black woman attending a debutante cotillion in New Orleans to an elegant image of the Hollywood starlet Mia Farrow, shot over her bare shoulder and highlighting her bony back.
N fertilizer savings across Europe [51], in rotations including leguminous crops, range around 277 kg ha−1 of CO2 per year (1 kg N = 3.15 kg CO2, [42].
Yield and soil water content simulated with the APSIM model were compared with measured wheat yield (range: 0.6 3.7 t ha−1), and measured soil water content in wheat and canola crops (range: 0.010 0.205 cm3 cm−3).

Large discrepancies exist in the literature on the area available globally for cultivation of bio-energy crops: projected areas for bio-energy crops range from 0.6 to 37 million km, that is, 0.4 28% of the earth's lands except Greenland and Antarctica (Table 1).
In the Andes, crops ranging from quinoa and amaranth to thousands of kinds of potato, flourish from sea level to the 15,000ft (4,570m) snowline.
