Return on Investment Case Study // Accelerating Solar Water Pump Sales in Kenya

This Return on Investment case study by Winrock International shows an increase in gross profits of up to 186% within one to two crop seasons after purchase of a solar water pump (SWP) for smallholder farmers in Kenya. Between August 2015 and December 2016 Winrock demonstrated SWPs to more than 16,000 of such smallholder farmers and found that despite strong demand, the lack of smallholder credit options for solar irrigation is a key obstacle preventing SWP sales from increasing rapidly; financial institutions and SWP retailers need technical assistance to facilitate smallholder access to credit.

For this reason, planning is needed that transcends different sectors, such as that sought by governments at the national and local levels.

Le Barrage de Fomi // Potentiel pour Un Projet d’Intérêt Commun

Par Luca Ferrini & Lucia Benavides. Cet article explique comment le projet de barrage de Fomi, qui a récemment regagné le monumentum, marque une grande opportunité d'intégrer l'approche Nexus dans le processus de planification comme un outil d'aide à la décision.
