Low  emissions  agriculture:  Suppor3ng  agricultural  development  that  GHG  emissions    or  sequesters  carbon.      

What  it  does  -­‐  Es3mate  GHG  emissions  for  different  land  use  systems  according  to  management  types;  

-­‐  Rank  the  most  effec3ve  mi3ga3on  op3ons;  -­‐  Es3mate  the  mi3ga3on  poten3al  of  different  op3ons.  

 What  it  does  not  do    

-­‐  Es3mate  life  cycle  assessment  of  GHG  emissions;  -­‐  Scale  emissions  up  to  total  area,  total  livestock;  -­‐  Es3mate  GHG  emissions  in  different  microclimates;  -­‐  ….

-­‐  Tool  to  help  providing  advice  for  policy  makers    

-­‐  Accommodates  regional  differences  

     

GHG  emissions:  main  input  variables  are  flexible  

•  Region,  climate,  soil  characteris;cs    •  Ecosystem:  upland  (34  crops  +  other),  rice,  grassland  

•  Current  management  prac;ces:  user  can  choose  which  prac3ces  they  are  using  (e.g.  fer3liser  applica3on  rate,  3llage  prac3ces).
