Field Exchange - Issue 36

Four of the six field articles in this issue of Field Exchange endeavour to demonstrate some form of intervention impact. The programmes are all very different; nutrition supplementation of HIV positive individuals in Zambia, community based nutrition programming in Bangladesh, a voucher scheme for fresh fruit and vegetables in a Dadaab refugee camp in Kenya and a joint cash and food programme in drought affected Swaziland. The programmes are either novel, i.e. the voucher scheme in Dadaab, are pilots contributing to a growing body of evidence, i.e. Zambia and Swaziland, or follow an approach for which there is a weak evidence base, i.e. the community-based nutrition programme in Bangladesh. All programmes therefore have a need to generate robust evidence of impact.
