A participatory and response-oriented nutrition causal analysis

(see more on the Link NCA web site)

The Link NCA is a mixed method to identify the most relevant factors leading to under-nutrition in a local context for improving Nutrition Security programming.

Why doing an NCA? «The Link NCA method was created with the objective of helping define response strategies for tacking under-nutrition. It is addressed to operational organisations, to authorities or governments, in charge of developing intervention policies. A Link NCA study is recommended for contexts that are not in crisis situations but where the problem of under-nutrition is widely established and where there exist high levels and different kinds of under-nutrition. It is especially advised for contexts where continuous attempts to fight this problem have been made but with little success.» (J. Morel, Nutrition Security Senior Advisor, ACF).

What is the Linik NCA? The Link NCA is a mixed method combining a strong and expert level qualitative component with a descriptive quantitative component to answer the following research questions:

  1. What is the prevalence and severity of wasting and/or stunting in the study population ?
  2. What is the prevalence of key risk factors for under-nutrition among the population ?
  3. What are the causal “pathways of under-nutrition” ?
  4. How have the prevalence and causes of stunting and/or wasting in this population changed over time?
  5. Which causal pathways are likely to explain most cases of under-nutrition?
  6. What recommendations can be made for improving nutrition security programming?

The Link NCA is studying local population, typically at a scale of a district or a livelihood zone.
