Do Climatic shocks matter for Food Security in Developing Countries?

This paper analyzes the effects of climatic shocks on food security, using panel data from 77 developing countries. The study applies econometric methods to examine the impact of rainfall volatility on the percentage of undernourished population and per capita food production index.

  1. Do Climatic shocks matter for Food Security in Developing Countries? KINDA S Romuald & BADOLO Felix

  2. Outline • Objective & Motivation • Literature Review • Determinants of food security • Effects of Climate Change on Food Security • Empirical analysis • Conclusion

  3. Objective The paper aims: • To analyze the effects of climatic shocks on food security (Percentage of total undernourished population, Per capita food production Index) • We use aggregated panel data over 1960-2008 for 77 developing countries • We apply modern econometric methods : Fixed Effects

  4. Motivations • Regain and importance of the climate change debate (Copenhagues (2009)) • Authors apply microeconomic studies on Climate change and agriculture • Originality: macroeconomic study ( 77 developing countries), econometric method (Fixed effect)

  5. Literature review (1) • Determinants of food security • Definition of food security (FAO (2001) • Microeconomic Causes -Low rate of agricultural production (FAO, 2004) -Low access to food supply -infrastructures and local markets -environment health • Macroeconomic Causes -Economic performance (Pritchett & Summers,1996 Wiesmann, 2006)

  6. Literature review (2) -Population growth (Birdsall & Sinding (2001), Merrick (2002)) -Trade policy (Merrick (2002) -Political institutions (Sen (1999), Sen (2000); Wiesmann (2006)) • Effects of Climate Change on Food Security • Effect on food availability (Schmidhuber and Tubiello (2007), Porter and Semenov(2005), Wheeler et al.(2000), IPCC (2007c)) • Effect on food stability (FAO (2008), IPCC ( 2001))

  7. Literature review (3) • Effect on food utilization (Taub and al. (2008), McMichael and al. (2006) Canfalonieri and al. (2007) • Effect on food accessibility (Du Toit and Ziervogel (2004), Thomsen and Metz (1998))

  8. Empirical analysis (1) Analyze effects of climatic shocks on food security Estimation method With X : { income per capita, inflation, rainfall, population growth}, error term, time effect and country fix- effects. variable of food security:

  9. Empirical analysis (2) - Proportion of undernourished population -Index of per capita food production Heterogeneity: African countries Estimation strategy : Fixed Effects (FE)

  10. Empirical analysis (3) Sources -World Development Indicators (2011): proportion of undernourished people, index of per capita food production, income per capita, inflation, population, cultivated lands -Guillaumont P and Simonet C (2011): rainfall volatility, rainfall, positive and negative rainfall shocks

  11. Empirical analysis (4) Rainfall volatility increases food insecurity in DC: • It has a positive effect on percent total undernourished pop. • It has a negative effect on Food production Level of rainfall has no effect on food insecurity (food production, the percentage of total undernourished population) Results are robust with control variables

  12. Empirical analysis (5) (economic development, Demographic expansion, inflation and cultivated lands ) • The effects of rainfall shocks on food security are different for African countries?

  13. Empirical analysis (6) Results suggest that African countries are more vulnerable to rainfall instability than other regions The effect of rainfall inst on food insec (percent tot undernourished population, food prod) is higher in Sub Sahara countries than in other regions.

  14. Conclusion (1) • Weanalyze the effect of climaticshocks on Food security • Period:1960-2008 , 77 developing countries • Rainfallinstability (negativerainfallshocks) increasesfoodinsecurity in DC • The effectishigher in Sub Sahara countries ( 30 countries) than DC • The level of rainfall has not effect

  15. Conclusion (2) • Policies recommendation: • One of them is the diversification of African economies that are less reliant on agriculture. • These countries should adopt agricultural techniques that optimize water use through increased and improved irrigation systems and crop development.
