SEIPS Interview: Make solar power, not tobacco

March 18th, 2018|

by Janet Pelley / Originally posted by Ecological society of America

Tobacco farmers could make more money if they replaced their crops with solar panel arrays, concludes a new study (Land Use Policy 2018; doi.org/10.1016/j.landusepol.2018.01.010).
