2. 1. Dry spell mitigation to upgrade semi-arid rainfed agriculture : Water harvesting and soil nutrient management for smallholder maize cultivation in Machakos, Kenya

   Author : Jennie Barron; Carl Folke; Theib Oweis; Stockholms universitet; []
   Keywords : ;

   Abstract : Improvements in on-farm water and soil fertility management through water harvesting may prove key to up-grade smallholder farming systems in dry sub-humid and semi-arid sub-Sahara Africa (SSA). The currently experienced yield levels are usually less than 1 t ha-1, i.e. READ MORE

4. 2. A bird's eye-view of smallholder productivity : Current measurement shortfalls, farmer perceptions and rationality on rainfed family farms in Ghana

   Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; Smallholder productivity; measurement shortfalls; maize yield levels; aerial photos; farmer attitudes; Ghana;

   Abstract : Smallholder farming, which is largely rainfed and relies on mostly rudimentary tools, predominates Ghana’s agricultural sector. The sector’s importance to the national economy is exemplified in not only the proportion of the active national labour force engaged in it but also in terms of its export earnings and service as a source of food for the vast majority of the population.
