International Agricultural Expert for Palm Trees, Coconut & Cotton


About 2022

Since long I have not updated my personal portal. Before I jump in to my present status, I would like to briefly give the past experiences.

After my tenure at King Saud University I moved to the YALA group as a consulting professor for Date Palm and introduced several agricultural practices to help in production and protection of date farms in vast areas of Al Qassim, Saudi Arabia. With Chairman’s support I have been able to introduce sniffer dogs for the early detection red palm weevil infestations in young date gardens. Good Agricultural Practices for date palm cultivation have been strengthened with introduction of several new items.

Worked as a member of high-level Red Palm Weevil Control committee of Food and Agriculture Organization of United Nations (FAO of UN) attended several meetings in Cairo and Rome and was instrumental in the publication of a valuable book on RPW.

Another long-term assignment with FAO in 2017-18 took me to Riyadh where a team of expert from various branches of agriculture under my leadership prepared blue print for the effective and efficient management of RPW in the Kingdom of Saudi Arabia. The Ministry of Environment, Agriculture and Water, Saudi Arabia conducted several interactive meetings in all provinces to understand the farmer issues especially date palm cultivation. Based on feedback received from farmers and agriculture officials, documents were developed for the management of RPW in a sustainable manner. I was also involved with the Public Investment Fund as a consultant in developing a new project related to agriculture. I assume the work is in progress.
