Introduction
currently, I am working on climate change adaptation helping my country fulfill the GCF requirements, stakeholder engagement, and building up and reviewing project concpet notes. Finished my Ph.D. 2021 with research on "Exploring the historical distribution of Dracaena cinnabari tree using ethnobotanical knowledge -Socotra Island, Yemen",. I have more than 25 years experience in natural resources management, biodiversity, community-based projects, and protected areas management.

Dracaena (Asparagaceae family) tree is famous for producing "dragon blood"—a bioactive red-colored resin. Despite its long history of use in traditional medicine, little knowledge exists on the genomic architecture, phylogenetic position, or evolution. Hence, in this study, we sequenced the whole chloroplast (cp) genomes of D. serrulata and D. cinn...
Background
In this study, we present and analyze toponyms referring to Socotra Island’s endemic dragon’s blood tree ( Dracaena cinnabari ) in four areas on the Socotra Archipelago UNESCO World Heritage site (Republic of Yemen). The motivation is the understanding of the past distribution of D. cinnabari trees which is an important part of conservat...

Various nontimber forest products (NTFPs) are produced from the forests and woodlands of Yemen. Dragon’s blood tree resin is one of the commercial NTFPs in Yemen and is produced by tapping Dracaena cinnabari trees, which are listed as vulnerable by the IUCN (International Union for Conservation of Nature) Red List. By applying a forest resource ass...
Dracaena cinnabari is a relict of the remote Socotra Island (Yemen) where it grows at higher altitudes with the frequent occurrence of fogs. D. cinnabari as the only representative of the dragon tree group creates woodlands and forests on the Socotra Island. It is not clear what mechanisms allow this relict arborescent monocot to survive harsh clim...
For the first time, in situ field measurements of sap flow were conducted in adult Dracaena cinnabari plant native to the arid tropical climate of Socotra Island. The heat field deformation (HFD) method was applied using both single and multi-point sensors to study azimuthal and radial sap flow variability in stem, roots and first-order branches ov...
The Socotra archipelago, Yemen, in the north-west Indian Ocean, has outstanding endemic biodiversity, and was listed as a World Heritage Site in 2008. Although inhabited for 6 millennia Socotra only began to open up to the outside world in 1990. With conservation interventions starting prior to major developments, and building on centuries-old low-...
This paper was prepared in response to the comments of the IUCN - World Heritage Site evaluation mission to Socotra island (November 2007). A common view on the importance and environmental impact of goats and other livestock in Socotra is presented by a team of ecologists, animal production scientists, and livestock herding practitioners with long...
