PROTOCOL: Evidence and gap map protocol: Understanding pathways between agriculture and nutrition: An evidence and gap map of tools, metrics and methods developed and applied in the last 10 years

The problem, condition or issueThe global food price crises of 2007-2008 and 2010-2011 drew attention to the need for addressing the underlying determinants of malnutrition in low-and middle-income countries (LMICs; Brinkman, de Pee, Sanogo, Subran, & Bloem, 2010;Webb, 2010).Specifically, as the primary source of food and income in LMICs, agriculture received renewed focus.Making agriculture work for nutrition-nutrition-sensitive agriculture-has climbed the international development agenda (Ruel, Alderman, & Maternal and Child Nutrition Study Group, 2013).More recently, given the sharp increase in diet-related chronic diseases underpinned by overweight and obesity in LMICs and the threats of climate change to diets, attention has expanded to leverage food systems to optimize nutrition, health and environmental outcomes (Johnston, Fanzo, & Cogill, 2014).Donors, researchers and implementers mobilized research agendas to invest in understanding how to strengthen agriculture and food systems to realize nutrition outcomes sustainably.Progress in this field in the last decade included three key developments:• Development of conceptual frameworks to aid the investigation of agriculture-food system and nutrition linkages, highlighting multiple direct and indirect complex pathways (Global Panel, 2015;
