Ruben specializes in water management and was once based at IRRI's Lao PDR Office.
Stationed at the IRRI office in Vientiane, Lao PDR, Ruben's work involved development of new techniques with national agricultural research and extension systems (NARES) partners in Asia to decrease water use in rice production and increase its water use efficiency. One such technique is what came to be known as alternate wetting and drying or AWD which is now widely promoted in a number of countries in Asia. Ruben was also the key IRRI scientist working with national partners in China and Thailand for the Closing Rice Yield Gaps in Asia (CORIGAP) Project under the Irrigated Rice Research Consortium.
Ruben also developed training and e-learning materials for the Rice Knowledge Banks of partner countries using the validated water saving technologies, and has worked closely with NARES partners to develop policy briefs for local national governments. He provided technical backstopping to NARES partners in extension programs to scale out water saving technologies to extension specialists nationally and to farmers at a district level.
