Causes  of  Land  Degrada;on  -­‐  1  

Mining  ac:vi:es  

•   Mining  sites  are  abandoned  a=er  excava:on  work  is  complete  leaving  deep  scars  and  traces  of  over-­‐burdening.  

•   In  states  like  Jharkhand,  ChhaGsgarh,  Madhya  Pradesh  and  Orissa  deforesta:on  due  to  mining  have  caused  severe  land  degrada:on.

Causes  of  Land  Degrada;on  -­‐  2  • In  states  like  Gujarat,  Rajasthan,  Madhya  Pradesh  and  Maharashtra  overgrazing  is  one  of  the  main  reasons  for  land  degrada:on.  

•   In  the  states  of  Punjab,  Haryana,  western  UNar  Pradesh,  over  irriga:on  is  responsible  for  land  degrada:on  due  to  water  logging  leading  to  increase  in  salinity  and  alkalinity  in  the  soil.

Causes  of  Land  Degrada;on  -­‐3  

Mineral  processing            Industrial  effluents  

• The  mineral  processing  like  grinding  of  limestone  for  cement  industry  and  calcite  and  soapstone  for  ceramic  industry  generate  huge  quan:ty  of  dust  in  the  atmosphere.  It  retards  the  process  of  infiltra:on  of  water  into  the  soil  a=er  it  seNles  down  on  the  land.    

• In  recent  years,  industrial  effluents  as  waste  have  become  a  major  source  of  land  and  water  pollu:on  in  many  parts  of  the  country.

Conserva;on  of  Land  Resources  -­‐  1  

Afforesta:on          Shelter  belts  of  plants  

•   Afforesta:on  and  proper  management  of  grazing  can  help  to  some  extent.  

•   Plan:ng  of  shelter  belts  of  plants,

Conserva;on  of  Land  Resources    -­‐  2  

Controlling  overgrazing          Stabilising  sand  dunes  

• Control  on  overgrazing,    

 •   Stabilisa:on  of  sand  dunes  by  growing  thorny  bushes.

Conserva;on  of  Land  Resources  -­‐  3  

Management  of  waste  lands        Controlling  mining  ac:vi:es        Proper  disposal  

• Proper  management  of  waste  lands,    

 

•   Control  of  mining  ac:vi:es,    

•   Proper  discharge  and  disposal  of  industrial  effluents  and  wastes  a=er  treatment.
