Tropical countries in global south like mine (Colombia) have huge social pressure on steep lands. They ought to be preserved in native forest, but people need to eat, so agroecology might emerge as solution. One way to make it acceptable for institutions is to argue this land use improves rives, in terms of lotic habitats, morphodynamics (less sedimentation) and water quality for intakes. Is it reasonable? suggestions? examples?. Thanks!
Important issues. The impact of agriculture on the condition of rivers, including the quality and purity of water in rivers is high. The fertilizers flowing into the rivers cause the change of the biological ecosystem in rivers. The mountain rivers in some countries are among the only ones not yet heavily polluted.

Necessity is the mother of all inventions and I must say that this is one of the adaptive approaches suggested. Most common drivers of deforestation is not people’s need but the market greed, if we reduce your consumption to minimum it would be wonderful. This is often not the case and hence deforestation has emerged as one of worst blot on mankind. Agro forestry, legume intercropping and planting high value crops could reduce some of these evils. However increased use of pesticide, agrochemicals, fertilizers and erosion may pose threats. Public participation and making them part of conservation and also involving them in decision making could do wonders. At the same time I feel that human population growth should be reduced. Remember the old saying by Malthus “Our food resources grow arithmetically but our population is increasing geometrically”
If the problem is to convince the politics that destructing the soil cover will bring erosion, juste cite Platon in Critias, and everyone will understand that erosion and its cause was known since the very ancient time.
