Deforestation occurs around the world, though tropical rainforests are particularly targeted. Elle est aussi un facteur de fragmentation écopaysagère qui diminue la résilience écologique des forêts. Herpetofauna are sensitive to environmental changes and their population is decreasing worldwide due to land-use change, depredation by introduced species, infection by diseases, release of toxic material in environment, overharvesting, and effect of climate change (Jolley et al., 2010; Colino-Rabanal and Lizana, 2012; Rais et al., 2015). A worrying feature of these findings is that policies aimed at stimulating regional development may stimulate further deforestation.

The rising population has set an alarming situation for the modern climate situation. Causes of Deforestation: Direct Causes People have been deforesting the Earth for thousands of years, primarily to clear land for crops or livestock. To assess the restoration potential of conifer forests and reduce land degradation by Germplasm Movement Zones (GMZ), priority zones for restoration were compared with areas that po ssess most effective restoration efforts: survival rate of planted seedlings, number of nurseries (N), Germplasm Production Units (GPU) and Germplasm Banks (GB) with data from Conafor corresponding to the 2016-2018 period. Process: A competitive global economy drives the need for money in economically challenged tropical countries. Deforestation causes can either be direct or indirect. According to the variables used in the comparative analysis, eight GMZ (XII.4, XII.5, X.3, X.2, XII.1, V.3, XII.2, and XV.1) were identified as restoration potential zones because their priority areas could be totally reforested by using Pinus and Abies species. Water is one of the basic necessities of life on this planet Earth. The study also found that greater off-farm employment opportunities were associated with less forest clearing.
