7. A variety of logical frameworks are used to diagnose problems and guide interventionThe UNICEF framework The FAO FIVIMS framework
8. Each logical framework posits similarbut somewhat different relationshipsThe Massett (2011) framework, with 7 IFPRI-USAID pathways highlighted by Webb (2013) The Gillespie et al. (2012) framework
9. The causal framework of economics makes a specific predictionSource: W.A. Masters, “Economic Development, Government Policies and Food Consumption”, chapter 14 in Jayson Lusk, Jutta Roosen and Jason Shogren, eds., Oxford Handbook on the Economics of Food Consumption and Policy, 2011.If households are actively trading, then farm production could be separable from consumptionDiets and health then depend on income, prices,access and use, rather than justfarm production...
