Natural disasters trend is increasing as well as their human and infrastructure effects; the two main causes are the hydrometeorological phenomenon like rainfall and human activities like poor land management, deforestation, overgrazing, urban expansion without planning. The economic losses were approximately of Col $25.000 millions (prices for year 2000).
