I just finished a fascinating book on scarcity. It's called Scarcity:Why Having Too Little Means So Much. A review of the book is linked here.
http://www.theguardian.com/books/2013/sep/07/scarcity-sendhil-mullainath... The book examines scarcity in all forms. Scarcity of food, love and time. There are a lot of important lessons for people who work in programs that aim to improve the lives in resource poor communities. It discusses how when people's "bandwidth" is taxed by the challenges of their lives due to poverty and hungry it can make it especially difficult for them to access services that are available to them (eating better, remembering to get their child vaccinated, taking medications regularly etc) and how our programs can take this into consideration.
Has anyone else come across this book. Did you find it useful in the work that you do?
