It is natural that we have to reafforest first any area which will carry hard woods, even those at the present moment carrying soft wood.
Aid should be used to reafforest denuded land, find water in drought areas and improve subsistence agriculture, not to provide more power stations for capital cities.
The world to-day cannot expect to get woodlands of this kind reafforested by natural regeneration at anything like the speed at which they are being devastated.
If we can breed and produce novel crops which will grow in saline or drought conditions to a great extent, that will do much to stabilise desert and help reafforest.
There are, of course, still people who prefer to see what they call picturesque woodlands, and complain when woods are cut down and reafforested on proper forestry lines.
We reafforested on a very limited scale.
