Ridge to Valley – a Holistic Watershed Perspective

This excellent little 20-minute video does a great job of covering the basics of watershed management and landscape rehydration. You won’t hear the words ‘permaculture’ or ‘swales’ once, but it’s clear that both are in use here, to great effect. If we can get these simple but profound concepts driven into social consciousness, and applied broadscale, we would see that investment in labour pay dividends, as many of our increasingly expensive natural disasters and resource limitations would simply disappear, as we reinstate nature’s own moderating capabilities.

Our environment is progressively getting degraded because of overexploitation of natural resources. In a degraded landscape with little or no tree cover, and subsequently little soil cover, rainwater is not able to percolate into the ground. We lose rich top soil with this running water, which flows away into the streams. It is a vicious cycle — no top soil, no vegetation, increased run off of water and further erosion of top soil. Holistic watershed development is the answer to break this vicious cycle.

This video film explains the importance of the ‘Ridge to Valley’ approach. It explains the various area treatments in non-arable waste land, cultivable land and also speaks about drainage line treatments. This video film highlights the technical and social components and the reasons why watershed work should start from the ridge and progress downwards towards the valley. — YouTube
