Development scenario precipitation was calculated with base scenario dry season, to preserve comparability. Development scenario dry-season length was used in calculation of dry-season change. Savanna systems included here are south of the Rio Negro and main stem of the Amazon River, east of Manaus.
*Each of the three entries under Dry-season length is an average calculated over all pixels in that part of the ecosystem that grew drier.
