It depends on geographical conditions, fertility of soil and Majorly Environmental issues for which our state Karnataka have good forests which is good thing and also we have less fertile lands compared to big barren states which u mentioned so its not equal to compare all States in same category for LA issues.. Ppl down South think more on environmental and health issues rather then going for development of infra by sparing environment.. Especially in Karnataka, Kerala, Tamil Nadu and some parts of Andhra Pradesh too.
