GARISSA, Kenya, 12 September 2011 – Dekha Mohamed Noor, 15, has not seen her family for more than a month. At the end of July, after schools closed for the August holidays, they sent her to live with a relative in Garissa, a bustling commercial hub 165 km west of her home village, Modogashe. The drought in north-eastern Kenya and much of the Horn of Africa had decimated their livestock, throwing the family into a desperate scramble for survival.
