Is it feasible to build a REL following an accuracy oriented approach?

Firstly,  �the  best  starting  point  for  creating  REL/RLs  is  the  use  of historical  data.  Adjustments  could  then  be  made  for  national circumstances  if  justified.  Deforestation  is  highly  complex  ‐ drivers vary significantly by region and are subject to a range of unpredictable variables. Degradation is even more complex. Therefore it is extremely difficult  to  accurately  predict  long‐term  future  deforestation  and degradation rates.� *

Secondly, to establish REL/RLs assumptions are necessary, taking into consideration the need for conservative approaches.
