    15. 15. Fire Monitoring Steppe and forest fires kill wildlife and also reduce the area of habitat available. Low humidity, a dry climate, and strong winds in the dry season make Mongolia one of the most fire-prone countries in Asia. 1996 1997

    19. 19. In Mongolia, that word is Zud –a combination of blizzard and bitter cold, preceded by drought. Heavy snow falls caused adverse grazing conditions for livestock SEVERE WINTER CONDITION The ground can become frozen so hard that animals cannot graze and water cannot be easily extracted. Pasture land is used for winter season

    31. 31. Onggi river basin The lenght is 437km, site is 175 square km The Ongi river starts f ro m Khangai Range then acrossed 3 kinds of areas which are Mountain & Wooded area, steering plain area, gobi desert area. Geographical location: 47°10 'N - 44°00'N 101°20'E - 105°00'E Mining
    32. 32. Approximally 60 thousand people and over one million livestock who one living around Ongi river one getting defective of drink water and pasture because of Ongi river and Ulaan lake’s evaporation. During Mongolia’ s transition to a free market, socio-economic factors such as poverty and profit-seeking mining exploitation of the environment have contributed to its deterioration, and consequently, the loss in regional biodiversity, land degradation and vulnerability.

    34. 34. Example: Mining activities Big scaled mining in Central part of Mongolia. Need land reclamation.
    35. 35. Example: Mining activities Hand level mining contributes to land degradation, Increased small to large-scale mining, as well as illicit activity resulting in exploitation of the country’s mineral resources.

    39. 39. Mongolian GER simply means &quot;home.&quot; GER used by nomads Nomads civilization It is made of a wooden framework covered by large pieces of felt. A decorative cloth covering laid over the felt. Ger districts are characterized by high unemployment and poverty rates and have little or no water, sewer, or waste collection facilities or services contributing to increasing land erosion, and air and water pollution

    41. 41. <ul><li>Poor mining legislation and lack of appropriate regulation of mineral production. </li></ul><ul><li>One of the most significant dangers of unsustainable development is land degradation due to expanding mining processes. </li></ul><ul><li>Limited research projects that focus on monitoring the environmental impacts of mining on land degradation and water contamination issues, and how these impacts are linked to human health . </li></ul>Discussion
    42. 42. Discussion and Conclusion Contribution to plan for the future by making more educated decisions in the ecological issues such as mining, firefighting, forestry and biodiversity Mongolia’s climate change seems to be caused by combination of both human impacts and naturally occurring environmental changes Necessary of modeling of socio-economic factors and land Cover/use change using Remote Sensing/GIS We conclude that environmental issues such as pasture grazing, drought desertification dust storm contribute to land degradation and it will be presumably continue to increase in the future.
