Part of the significance of these primary landscape components is understanding how water moves in relationship to land shape [topography]. Water is the basis of all life on earth, and the limiting factor in most agricultural production. Managing water effectively is crucial for future-proof resilient food systems.
What you notice if you get a map out is that the valleys are a small percentage of any landscape, while ridges make up the majority of the landscape. In Yeoman’s work, He observed how valleys tend to have adequate water and that ridges tend to dry out, rendering them unproductive.

The speech by Patrick Moore PhD, GLOBAL WARMING POLICY FOUNDATION OCTOBER 30, 2015 is presented as a counter to the non-scientific dogma regarding reducing CO2 levels. Delivered by Patrick Moore, formerly President of Greenpeace Int’l, to the Institution of Mechanical Engineers in London. He is a vocal critic of faulty science that supports climate-change caused by humans. Since he was a legend in the eco-movement, his current assessment is credible and authoritative.
Should We Celebrate Carbon Dioxide?
My Lords and Ladies, Ladies and Gentlemen. Thank you for the opportunity to set out my views on climate change. As I have stated publicly on many occasions, there is no definitive scientific proof, through real-world observation, that carbon dioxide is responsible for any of the slight warming of the global climate that has occurred during the past 300 years, since the peak of the Little Ice Age. If there were such a proof through testing and replication it would have been written down for all to see.
The contention that human emissions are now the dominant influence on climate is simply a hypothesis, rather than a universally accepted scientific theory. It is therefore correct, indeed verging on compulsory in the scientific tradition, to be sceptical of those who express certainty that “the science is settled” and “the debate is over”.
But there is certainty beyond any doubt that CO2 is the building block for all life on Earth and that without its presence in the global atmosphere at a sufficient concentration this would be a dead planet.

Proponents of clean energy will soon have a new source to add to their existing array of solar, wind, and hydropower: osmotic power. Or more specifically, energy generated by a natural phenomenon occurring when fresh water comes into contact with seawater through a membrane.
Researchers at EPFL's Laboratory of Nanoscale Biology have developed an osmotic power generation system that delivers never-before-seen yields. Their innovation lies in a three atoms thick membrane used to separate the two fluids. The results of their research have been published in Nature.
