Defines which share of marginal land should be included (see options below) and whether suitable land under irrigated conditions ("irrigated"), under rainfed conditions ("rainfed") or suitability under rainfed conditions including currently irrigated land (rainfed_and_irrigated) should be used. Options combined via ":" The different marginal land options are:
"all_marginal": All marginal land (suitability index between 0-0.33) is included as suitable"q33_marginal": The bottom tertile (suitability index below 0.13) of the marginal land () area is excluded."q50_marginal": The bottom half (suitability index below 0.18) of the marginal land area is excluded."q66_marginal": The first and second tertile (suitability index below 0.23) of the marginal land area are excluded."q75_marginal": The first, second and third quartiles (suitability index below 0.25) of the marginal land are are excluded"no_marginal": Areas with a suitability index of 0.33 and lower are excluded.
