Pastoralist Survey Method (PSM)
Aim: to design, test and validate a new method for assessing the nutrition condition in pastoralist populations
Rationale: • Vulnerability of pastoralists to shocks• Lack of suitable survey method
Progress: Method designed & peer reviewed in 2007 First field test in Mali in 2008 Second test in Ethiopia in March 2010 Third test in Chad in May 2011
Funding: ACF and donors in each country Scientific partners: Anne Marie Mayer, Mark Myatt, Paul
Baxter – independent consultants

size
Sample size depends on• Prevalence estimate
(15%)• Precision (3%)• Average PSU size (15)
Sample size = 43 PSUs
Systematic sample of PSUs based on Social Organising Factor (e.g. water points) PSU: Primary Sampling
Units

PSM quantitative phase
Identify all eligible children (6-59 months)
Measure MUAC & oedema
Collect other data

Listening Posts – surveillance system
Aim: to design, test and validate a new method for Surveillance system which will be replicable and sustainable and which collects basic data on food prices, terms of trade and nutritional status
Rationale: • 2008 Food price crisis impact on nut status unknown• Absence or inadequate methods to link food insecurity and
economic status to malnutrition Progress:
Method designed & peer reviewed in 2009 ACF field test in Burkina Faso in 2010-2011 (ongoing) SC UK field test in Zimbabwe in 2010-2011 (ongoing) Soon a third test in Liberia in 2011 by ACF
Funding: ACF, SC UK and donors in each country Scientific partners: Mark Myatt – independent consultant

Listening Posts project>> HUnger Monitoring System (HUMS)
Livelihoods zones mapping with sentinel sites selected Small cohort of children 6-24 mo with renewed
inclusions Frequency: quarterly data collection Data on
• Staple food prices, • Terms of trade • Anthropometry• Food diversity and food frequency• Contextual information
And possibly secondary data on: • Feeding centre admissions • Changes in the minimum cost of a healthy diet • Food access • Coping strategies

HUMS dissemination
Presentation of the concept at WFP meeting, June 2009
Presentation at a meeting hosted by Institute of Medicine ‘Mitigating the Nutritional Impacts of the Global Food Price Crisis’ in Washington in July 2009
Article in a peer reviewed journal on the 3 experiences - 2012
Sharing of survey guideline & toolbox via a website?
Uptake by stakeholders in existing national surveillance systems

ACF Main sources of data
SMART SURVEYS:• Nut. Surv. DB: with around 1000 surveys from the 90’s
until now• Children Surv. DB: with around 370 000 children from
25 countries (from around 400 cluster surveys 2001-2010)
THERAPEUTIC PROGRAMMES: • Therapeutic Prog. DB: with around 73 000 SAM children
treated in 9 countries by ACF from 2005 until now.• Monthly report data: collected monthly with
beneficiaries information (data not centralized).

Improving data collection and use
How to estimate incidence of acute malnutrition to better tailor nutrition programmes size & resources?• Partnership with Health and Nutrition Tracking Service
(HNTS) project (C. Prudhon et al.) How to improve validity of nut surveys conducted
by NGOs? • SMART project: partnership with Centre for Disease
Control & Prevention (CDC) How to improve causal analysis of acute
malnutrition to better address it? • Nutritional Causal Analysis (NCA) applied research
project: partnership with Tufts University
How to transmit Knowledge to field teams !!
