Overgrazing over cultivation and deforestation

Sheikh, I. Northern mountains of Pakistan are the major source of water for Tarbela and Mangla dams. The economy of Pakistan is almost entirely dependent on agriculture. Instead of finding the beautiful park in her memories, she found only a barren stretch of land. The total geographical area of Pakistan is Deforestation occurs in many ways.

overgrazing and deforestation differ

Deforestation occurs for a variety of reasons regarding need for space or a need for resources from the trees. Normally, rights of use of Common land in England and Wales were, and still are, closely regulated, and available only to "commoners".

Overgrazing over cultivation and deforestation

However, the trees on our planet are being depleted at a very fast rate. The earlier projects, however, lacked community participation perspectives and imperatives. Importantly, land degradation is referring generally to the reduction or loss of the biological or economic productivity and complexity of land, whereas desertification is specifically referring to the degradation of drylands. Population for the Countries of the World. Intense summer rainfalls along with melting of snow in high mountains contribute to the soil erosion hazards. Inoue, M. There is an ever increasing number of births which translate to increased population levels in the world. In an investigation on salt-tolerant shrubs, Atriplex species displayed greater potential in highly saline soils Irshad et al. The inappropriate use of drylands, such as overgrazing, deforestation or inappropriate irrigation is mostly driven by demographic, economic and social-political factors. Honna, S. As protective plant cover disappears, floods become more frequent and more severe. This is when animals feed on vegetation and cause serious damage to our ecosystem Hogan. Grazing management, with sustainable agriculture and agroecology practices, is the foundation of grassland-based livestock production since it affects both animal and plant health and productivity. They are important for the climate of the Earth, as they act as filters of carbon dioxide. The country suffers particularly from overgrazing of pasture land, a major cause of human-induced desertification.

Salt-affected soils of Pakistan. Soil erosion in the water shed areas of rivers increases the sedimentation load, which ultimately reduces the storage capacity of dams.

The productivity of range lands is hampered by heavy livestock pressure. Another potential buffer is to plant warm-season perennial grasses such as switchgrasswhich do not grow early in the season. This leads to the erosion and oxidation of fertile soil.
