Mr. Ba-Jammal has had a truly pioneering influence on environmental protection in Yemen - a country which faces acute challenges from water scarcity to desertification. During his time as Minister and then Prime Minister, he established Yemen's Ministry of Water and Environment and Environment Protection Authority, solicited national and international funding for environmental conservation and sustainable water management, and implemented a series of groundbreaking environmental policies in Yemen and its region.

Mr. Ba-Jammal also orchestrated conservation efforts for the Socotra archipelago, a site of global importance for biodiversity. The Socotra conservation fund came into being under his patronage, and the archipelago was listed as a UNESCO Man and Biosphere reserve in 2003.

Among other achievements, Mr. Ba-Jammal also supported the declaration of several marine and land protected areas in Yemen and established a state agency for the development of Yemeni islands with a focus on marine resources conservation. Along with Mr. Ba-Jammal's work on Yemen's water sector, all these projects serve as key examples of environmental awareness in a region where water and conservation issues are of vital importance - increasingly so in a climate-constrained world.
