definitions wikipedia
Definitions (Wikipedia)
  • Food security refers to the availability of food & one's access to it. A household is considered food secure when its occupants do not live in hunger or fear of starvation.
  • Hunger is a feeling experienced when one has a desire to eat.
  • Malnutrition is the insufficient, excessive or imbalanced consumption of nutrients .
refugee situation
REFUGEE SITUATION
  • Food & nutritional security threatened
  • Malnutrition, disease & death
  • Refugees need partial/full food support (acute phase), +/- nutritional rehabilitation
objectives
OBJECTIVES
  • Objectives of food intervention programmes
    • Ensure adequate nutritional general food ration (GFR)
    • 2,100Kcal/person/day→ Prevent malnutrition/mortality
    • ↓ Prevalence/mortality from malnutrition
  • Role of health agencies: Rx of malnutrition/nutritional deficits
    • Selective feeding programmes
    • Monitor regularity & adequacy of food rations
    • May take charge of general food distribution
organization of food support world food program un high commissioner for refugees
Organization of Food SupportWorld Food Program & UN High Commissioner for Refugees
  • MOU (WFP & UNHCR) establishes responsibilities & coordination mechanisms for meeting food & nutritional needs of refugees
  • UNHCR food & nutritional coordinator - responsibility for coordination of all aspects of the program
  • Refugees (women) must be involved
  • Nutrition education
  • Aim of food programs:
    • Restoration & maintenance of sound nutritional status
    • Food ration that meets
      • Assessed requirements
      • Nutritionally balanced
      • Palatable & culturally acceptable
assessment of food nutritional situation part of initial health assessment
ASSESSMENT of Food & Nutritional Situation(part of Initial Health Assessment)
  • Phase I
    • Early, quick evaluation → severity of global picture
      • Need for rapid intervention
      • Facilitate planning necessary resources
      • Based on observation, interviews/discussions key informants
  • Phase II
    • Quantified data gathered on nutritional situation
    • Decides type & size of nutritional programs
    • Prevalence of malnutrition, food available/accessible, factors affecting nutritional status
    • Expensive, time consuming, not always feasible
assessme n t basic information
Assessment : Basic Information
  • Numbers & demographics
  • Current nutritional status
  • Milling possibilities
  • Food preferences
  • Family capacity to prepare, store, process food
  • Access to fuel, utensils, containers
  • Local food availability
    • Present/over time
    • Local food for purchase
    • Ease of access
  • Groups at risk
    • Who/ how many
  • Self reliance & coping strategies
assessment other important information
Assessment: Other Important Information
  • Health status & services
  • Environmental health risks
  • Community structure
  • Food distribution systems
  • Social-economic status
  • Logistics constraints
  • Security constraints
  • Availability of human resources
  • Storage capacity & quality
  • Delivery schedule of food & non food commodities
  • Other agencies activities & assistance provided:
    • Quantity, items, frequency
    • Selective feeding programs
food availability accessibility
Food availability & accessibility
  • Quantity/quality food (usually insufficient w/out distribution)
  • Initial data:
    • Food distribution already taking place
      • Food ration, frequency of distribution, distribution agency, target group
    • Assessment of local market
    • Food basket of individual households (by sample survey)
    • Food sources often diverse: food aid, shared w/ locals, food purchased/bartered for/ gathered
nutritional status of refugee population prevalence of acute malnutrition in u5 yrs age
Nutritional status of refugee population:prevalence of acute malnutrition in U5 yrs age
  • How to measure malnutrition
    • W/H index most reliable: reflects present situation, most sensitive to rapid change
    • Oedema→ severe malnutrition (Kwashiorkor)
    • MUAC: quick, high variability, rapid assessment tool
  • Implementation of nutritional survey
    • Sample of children 6mo-5yrs w/ W/H index
  • How to express malnutrition rates: Z scores
    • Global malnutrition: % children <-2 Z scores and/or oedema
    • Moderate malnutrition: % children < -2 Z scores > 3 Z scores
    • Severe malnutrition: % children < -3 Z scores and /or oedema
key nutritional indicators
Key Nutritional Indicators
  • U5Moderate Severe
    • W/H % of median value 70-79% < 70%
    • W/H in Z scores -3 to -2 Z < -3 Z (edema)
    • MUAC 115 - <125 mm < 115 mm (edema)

Interpretation of results
  • Essential indicators
    • Global acute malnutrition rate : 5% common in Africa/Asia, 5-10% should act as warning, > 10% serious
    • Severe acute malnutrition rate
  • Bias in estimating severity
    • Very hi MR among most vulnerable: under estimates malnutrition
    • Timing & season of the year
  • Distribution of malnutrition in population
    • Age grp, date of arrival, ethnic grp, camp section, etc
    • Helps target programs
  • Three main contextual factors
    • Mortality figures
    • General food rations & food accessibility
    • Major outbreaks of disease
planning quantity of food
Planning quantity of food
  • Based on demographic information & prevalence of malnutrition from nutritional survey
  • If presumption of major nutritional emergency, assume:
    • U5: 15-20% of total pop
    • Pregnant: 1.5-3% of total pop
    • Lactating: 3-5% of total pop
    • 15-20% moderate malnutrition
    • 2-3% severe malnutrition

class ical emergency food interventions
Classical Emergency Food Interventions
  • General food distribution
    • Ensure adequate food rations for all
  • Selective feeding programs
    • Targeted Supplementary feeding programs (SFP)
      • Moderately malnourished U5, selected pregnant /nursing women, referrals from TFP, other malnourished people & medically referred
    • Blanket SFP
      • Children <3 or 5 yrs age, all pregnant/nursing women, other at risk groups
    • Therapeutic feeding programs (TFP)
      • <5yrs severely malnourished, idem other age grps
      • LBW infants
      • Unaccompanied minors/orphans <1yr age
      • Mothers of <1yr infants w/ breastfeeding failure
how to decide on the intervention
How to decide on the Intervention
  • General food ration available
    • 2,100Kcal/person/day for all refugees
  • Malnutrition rate
    • Indicates level of intervention required
  • Aggravating factors: requiring ↑ level intervention
    • CMR > 1/10,000 day, ↑ level malnutrition
    • Inadequate food ration < 2,100Kcal/person/day
    • Epidemics: measles, cholera, shigella , pertussis, etc
    • Severe cold & inadequate shelter, ↑ level activity/males
    • Unstable situation: new influx of refugees
    • Wastage (grinding, poor storage), losses, ↑ barter for non food items
  • Other considerations
    • Vulnerabilities of specific grps, logistical constraints, agencies capacity, security, food basket unfamiliar to refugees, local nutritional status, etc
responding to crisis simplified decision tool
Responding To CrisisSimplifiedDecision Tool

[1] Aggravating factors are: i) General food ration below the mean energy requirement (<2100 kcal/kg/person), ii) Crude Death Rate greater than 1/10 000/day and iii) Epidemic of measles or whooping cough.

[2] This may include therapeutic care integrated into primary health system (hospitals and health centres).

implementation of gfr distribution main factors for success
Implementation of GFR distributionMain Factors for success
  • Political willingness (donors)
  • Adequate planning & good logistical organization
  • Registration of refugees, ration cards (UNHCR)

  • Inadequate nutrient content of ration (long term programs)
  • Food diversion
    • By households in exchange for non food items/complementary food items: positive effects
    • By powerful grps → inequities in access: security problem, detrimental effects
  • Poor organization of distribution & logistical problems: ↓security
  • Lack of coordination among partners supplying all items regularly
  • Problems w/ food preparation
    • Lack cooking utensils/fuel
    • Lack of knowledge to prepare items distributed
alternative to general food distribution
Alternative to General Food Distribution
