Extreme food insecurity: famine episodic crises, chronic hunger & malnourishment. Globally, 8 m deaths/year from lack of food & nutrition (24,000/day) 5. 8 m children die/year from hunger related-causes (16,000/day) ~ 1/3 of kids <5 moderately to severely underweight (fao hunger report, 2008) Sths: warm, dry sinking air control the location of the world"s deserts (~30o n&s) = controls on world climate & ecosystem distribution. Itcz, sths: don"t go straight across due to shape of continents & ocean effect. Itcz, sths: don"t go straight across due to ocean effect & shape of continents. Warm up & cool down to greater depths. Sahara extends very far b/c of isolation from ocean moisture sources. 15/10/2013 one of the most extremely seasonal parts of the planet. High moisture demand of plants relative to what is available. + soils can only hold a little water over time. = plants must adapt to extreme variations in rainfall.
