Forest fires : Disaster Management : Environment Geography

Image
  FOREST FIRES:   Vulnerability: 54.40% of forests in India are exposed to occasional fires North-Eastern India and Central India along with some patches in Western ghats, Uttarakhand etc. Causes: Natural :  Lightening  Volcanic eruptions Dry leaves litters Swaying of Bamboos Rolling stones Heat waves and high temperatures. Anthropogenic causes:  Shifting cultivation  Invasive species brought into forest as plantations, increasing vulnerability.        Eg Chir pine in Uttarakhand.  Deliberate fires  Camp fires and irresponsible tourism in forest Burning farm residues Forest Fire Management: Preventing Moisture retention measures – landscape management, artificial water sources inside forest.  Forest fire prone zone identification and mapping. Effective forest floor biomass management – controlled burning Firelines Weed management. Preparedness Vulnerability assessment Early Fire detection and response. Digitisation of fore...

Monsoon Climatic Type and Tropical Deciduous Forest Biome

Image
  CLIMATE : Monsoon Climate type BIOME : Tropical Deciduous forest Biome It is  generally found along the eastern margins of subtropical regions  Average annual range of temperature is between 32-40 degree Celsius with mean annual average temperature is 27 degree Celsius. Typically characterized by two phenomena Seasonal reversal of winds Fixed period of rainfall The monsoonal regions are given in the map below : They are a degraded form of tropical rainforest with two canopies of trees.  The forests are more open resulting in penetration of sunrise paving way for growth of grasses and shrubs. Average annual precipitation is between 100cm and 200cm.  The coastal areas receive more precipitation while  the interior areas are generally dry. The heavy rainfall in the region lead to excessive leaching away of the topsoil, resulting in formation of Latosols.  Climatic conditions of the region are highly influenced by the shifting of wind belts. Vegetat...
