why does Telangana not receive more rainfall
Answers
Answer:
Because telangana is far from the sea
Telangana is a semi-arid zone and has a predominantly hot and dry climate. The areas covered by the Deccan Plateau are characterized by hot summers with relatively mild winters. Telangana has historically been prone to drought conditions especially in Rangareddy, Mahabubnagar and Nalgonda districts. Climate is projected to increase drought occurrence in the districts like Nalgonda and Mahabubnagar which would impact not only water resources but also have a cascading effect on other dependent sectors. Increased drought conditions can also severely affect agricultural and pastoral livelihoods and increase vulnerability and risks for farmers, and people depending on such livelihoods.
Major Climate Change issues for the State arise in the agriculture and forestry sectors and in relation to the droughts and heat waves. Agriculture is severely affected by variability in rainfall and temperature patterns. Besides these, other critical areas of concern are food security, increasing number of climate vulnerable habitats (like slums or village dwellings) and climate vulnerable infrastructure (like roads and bridges which may be washed away by floods).
Summers start in March, and peak in May with average high temperatures in the 42 °C (108 °F) range. The monsoon arrives in June and lasts until September with about 755 mm (29.7 inches) of precipitation. A dry, mild winter starts in late November and lasts until early February with little humidity and average temperatures in the 22–23 °C (72–73 °F) range.
Telangana State is geographically located in a semi-arid area and has predominantly hot and dry climate. Summer starts in March, and reaches peak in May with average high temperatures of 42°C (108°F) range. The monsoons enter into the State in June and lasts until September with about 700 mm of precipitation. A dry, mild winter starts in late November and lasts until early February with little humidity and average temperatures in the range of 22–23°C(72–73°F). The State is also prone to hailstorms in the month of April and May, occasionally. Rainfall
The average or normal rainfall of the State is about 905.3 mm and about 80% of annual rainfall is received from the south-west monsoons alone during (June to September). The rainfall in the State is erratic and uncertain and distribution of the rainfall is uneven in various mandals thus, making agriculture a proverbial gamble with the monsoons. During the period from 2004-05 to 2014-15, the annual actual rainfall received was lowest in 2004-05 with 614 mm, where as it was the highest in 2013-14 with 1212.2 mm as against normal rainfall of 905.3 mm in the State.
Irrigation is the artificial application of water to the land or soil. It is used to assist in growing of agricultural crops, maintenance of landscapes, and re-vegetation of disturbed soils in dry areas and during periods of inadequate rainfall. Irrigation is one of the most important critical inputs for enhancing the productivity that is required at different critical stages of plant growth. One cannot imagine agriculture without irrigation. Two important rivers of India, the Godavari and Krishna are flowing through the State and providing irrigation.
Major sources of irrigation in the state are canals, tanks, tube wells, dug wells etc., and irrigation is being done with the use of various techniques such as surface irrigation, localized irrigation, drip irrigation, sprinkler irrigation, sub-irrigation depending upon the availability of source, accessibility and others to increase the productivity of the crop grown.
Tanks are the main source of irrigation in Telangana for centuries. Over a period of time, due to lack of proper maintenance and siltation, most of these tanks have either shrunk or become defunct. Reduced availability of surface water has resulted in over stress on the available ground water resources. In the state, there are about 46,531 minor irrigation sources.
Telangana is centrally located in Deccan Plateau where lots of undulations, hillocks, rivers, rivulets, streams etc are found. Telangana area is blessed with ample rainfall of around 900 mm. These geographical conditions invariably led to the construction of water shed structures i.e tanks to catch hold rain water in monsoon season. Villages were established on the higher part of a stream / rivulet and an earthen bund was constructed across the stream to store water and agricultural activities were carried out downstream of tank.
