Ultimately, the process leads to the inability of the individual to acquire sufficient food to sustain life.”* #### Walker, 1989 --- # Declaring a famine ### *“There is still a major controversy over whether the Ethiopia crisis of 1999-2000 should be labeled a 'famine' or not, in light of the emotive and political connotations of the word. In the author’s view - given the number of people affected, the damage to livelihoods and human development, and the loss of human life - there is no question about whether Ethiopia 1999-2000 was a famine. But the continued controversy over this issue points to the need for a broadly accepted operational definition of famine.”* #### Maxwell, 2005 --- # Declaring a famine * Highly politicised label * When is a ‘famine’ declared and who decides? * Incentives or disincentives to declare * What are the information needs and how reliable are information sources? --- # Food availability decline (FAD) * Supply theory of famine * Shortage of food * Assessed through estimation of * Food production (+) * Imports (+) * Exports (-) * Wastage (-) * grain needed for sowing (-) * residual stocks (+) --- # Causes of FAD * Drought or floods * Diseases of plants or animals * Declines in soil productivity * Conflict * Government policies (e.g. cash cropping) * Regulations on land use * Trade regulations * Alternative use of agricultural production (e.g. Food as fuel) --- # Food entitlement decline (FED) * Demand theory of famine * Failure to demand even when supply sufficient * Types of entitlements (entitlement set): * Ownership * Exchange * Non-market * Relationship between non-food and food prices * Famine may result form a change in the price of key items in the entitlement set --- # Market failures * Imperfect system of distribution * Infrastructure * Transport (ownership, repair, alternative uses) * Physical fragmentation * Transaction costs & risks (physical isolation, imperfect information) * Speculation and hoarding * Collusion of merchants to artificially limit supply in order to increase costs and profits --- # Modern famines * Complex combinations of many factors including FAD and FED and market failures * Conflicts and/or sanctions * Pandemic (?) --- class: inverse, center, middle # Interventions: what works and what have we achieved? --- background-color: #FFFFFF .center[![](https://globalnutritionreport.org/media/images/Fig-1.3.width-1200.png)] --- background-color: #FFFFFF .center[![](https://globalnutritionreport.org/media/images/Fig-1.5a.width-1200.png)] --- class: inverse, center, middle # Development interventions in relation to nutrition outcomes --- background-color: #FFFFFF background-image: url(https://scalingupnutrition.org/wp-content/uploads/2017/02/Framework-of-Actions.jpg) background-size: 95% ??? * Impact of development interventions is a mixed bag * Complexity and fluidity of the on-the-ground situation often not matched by the modality and implementation of the interventions * Scaling up of interventions to reach greatest coverage continue to be a problem even in non-crisis/famine situations and fails terribly in crisis situations * Continuing tension between development and humanitarian interventions; between sustainable response or emergency response --- background-color: #FFFFFF # Food systems approach .pull-left[ Encompass the entire range of actors and their interlinked value-adding activities involved in the production, aggregation, processing, distribution, consumption and disposal of food products that originate from agriculture, forestry or fisheries, and parts of the broader economic, societal and natural environments in which they are embedded. ] .pull-right[ .center[![](https://nutritionconnect.org/sites/default/files/inline-images/FAO%20and%20INRAE%202020%20diagram.png)] ] --- class: inverse, center, middle # Questions? --- class: inverse, center, middle # Thank you!
