This project aimed to improve soil and irrigation water management to sustainably improve vegetable yields and household economies.

Lao PDR and Cambodia are developing countries with low agricultural productivity. Better management of soil and water resources could help smallholder farms to sustainably produce more vegetables. Socio-economic, livelihood experiences and expectations and organisational constraints affect how and whether smallholders adopt technology, while input supplies, finance, labour, information, and professional human capital are often inadequate.
