Evidence and Gap Map


Welcome to the IMMANA Evidence and Gap Map (EGM), which summarises research innovation in tools, metrics and methods to understand food systems and agriculture-nutrition linkages in the last ten years.  

Rationale for an Evidence and Gap Map

Agriculture, food systems and nutrition pathways are recognised for their importance in health outcomes (human and planetary), but these relationships are complex, dynamic and hard to measure.  To address this challenge there has been a necessary proliferation of new tools, metrics and methods in the last decade through renewed interest and funding at this multidisciplinary nexus. Projects such as: Sustainable and Healthy Food Systems (SHEFs), INDDEX, Global Dietary Database (GDD), CGIAR Research Program on Agriculture for Nutrition & Health (A4NH), and IMMANA are examples of these efforts. 
However, in order to guide further research, future investments and policy decision-making it is important to understand which tools, methods and metrics exist and to what extent they have been developed and tested. To address this we used an Evidence and Gap Map synthesis methodology. This approach is similar to both systematic and scoping reviews, with a systematic search strategy that is designed to be comprehensive, but not necessarily exhaustive. An Evidence and Gap Map functions to highlight evidence that exists and that doesn’t exist, usually against a conceptual framework. It's major output is an interactive framework map that can be filtered by various categories, sub-divided and tabulated by users. It provides both macro and micro information on a topic but does not meta-analyse or provide effect estimates.
A detailed methodological protocol that explains the process of creating the EGM is available at https://onlinelibrary.wiley.com/doi/full/10.1002/cl2.1035.  

Explore the map and data portal

There are two primary resources associated with the Evidence and Gap Map. As this is the beta version of the Gap Map and the first public use of this resource, it is designed to be a living and evolving tool so we welcome any feedback, ideas and comments. 

1. The map 

An interactive framework map that allows users to navigate through the results of this synthesis exercise, to visually highlight and explore evidence that exists and that does not exist. 

2. Data portal

A portal allowing users to explore the data independently from the map by choosing various codes.

Webinars and training videos

In the coming weeks we we will be uploading a training video on how to use the map and data portal. There will also be a live webinar taking place in mid-November (date TBC) in which users can interact, ask questions and learn how to navigate and interpret the information. In the meantime, Thalia Sparling's presentation of preliminary Evidence and Gap Map results at ANH2019 in India can be viewed below:
