Experts see ag observations from space as helpful but with challenges (the fence post) 

The Fence Post published an article stating that observations of agriculture from space can help predict global food security problems and help farmers be more efficient, but there are still challenges in using the technology, particularly in addressing sustainability. Experts said that making observations of fields and crop production is much easier today than in the past because there are more satellites to make the observations. Senior research fellow Jawoo Koo said, “pre-warnings from satellite data can become inaccurate if, for example, rains come late in the season. Accurate data is vital for crop insurance programs.”
