- Resilient food and nutrition security for Yemen through agricultural interventions and capacity building in the small ruminant dairy and agriculture sector (SURE-RESULTS): Final ReportAuthor(s): Rekik, Mourad (International Center for Agricultural Research in the Dry Areas (ICARDA), 2026-06-10)Date: 2026-06-10Type: Internal ReportStatus: Timeless limited accessThe Resilient Food and Nutrition Security for Yemen through Agricultural Interventions and Capacity Building in the Small Ruminant Dairy and Agriculture Sector (SURE-RESULTS) project was implemented by ICARDA across Abyan, Aden, Lahj, and Taiz governorates to strengthen food security, agricultural resilience, and livelihoods through interventions focused on the small ruminant dairy value chain and climate-smart agriculture.
- Technology validation report for controlling RPW.Author(s): Nejatian, Arash; ElShafie, HamadttuDate: 2026-08-06Type: Internal ReportStatus: Open accessRed Palm Weevil (Rhynchophorus ferrugineus, RPW) remains one of the most destructive pests of date palm production systems, particularly in arid and semi-arid regions where date palm is economically, culturally, and strategically important. The pest is difficult to control because its most damaging stages occur inside the palm trunk, where larvae feed internally and infestation symptoms often become visible only after significant damage has occurred. As a result, conventional control approaches based only on visual inspection or reactive treatment are often too late, costly, and insufficient. Effective RPW management therefore requires a technology-based, integrated, and preventive control strategy. No single technology can fully address the RPW challenge. Prevention, early detection, targeted treatment, sanitation, and removal of severely infested palms must be combined into a coordinated management package. This report assesses available and emerging technologies for RPW control and classifies them according to their function, technology readiness, deployment feasibility, and validation potential. The report builds on the technology profiling and prioritization work conducted for RPW infestation solutions. The source material identified and assessed technologies across the RPW control value chain, including prevention, detection, treatment, and revival/removal. The technologies were also classified by technology family, including digital, biotechnology, and material-based solutions. The prioritization spreadsheet further evaluates technologies according to effectiveness, environmental impact, infrastructure readiness, talent readiness, and financial feasibility, with separate sheets for TRL 1–6 and TRL 7–9 technologies. The purpose of this report is to translate the available technology profiling information into a practical technology assessment and validation framework. The report does not treat all technologies equally. That would be a bad decision-making approach. Instead, it separates technologies that are ready for field deployment from those that require controlled validation, pilot testing, or continued research. This distinction is critical for designing realistic RPW control programs, especially under UAE or GCC test-bed conditions.
- Delivering rust resistant wheat to farmers: A step towards increased food securityAuthor(s): Joshi, Arun Kumar; Azab Moustafa, Moustafa; Mosaad, M.

P.; Payne, Thomas; Braun, Hans-Joachim (The Borlaug Global Rust Initiative (BGRI), 2010-06-20)Date: 2010-06-20Type: PresentationStatus: Open accessAn important step towards reducing the vulnerability of wheat in Africa and Asia, to the Ug99 race of the stem rust pathogen, is the substitution of current susceptible varieties with superior resistant varieties. In the 2008–09 cropping season, both seed multiplication and dissemination of Ug99 resistant varieties was initiated in Nepal, Bangladesh, Afghanistan, Pakistan, Egypt, Ethiopia, Iran and India. Ug99 resistant varieties must occupy about 5% of the area sown to wheat in each country to ensure sufficient seed to displace current popular varieties. Because of the underdeveloped seed industry and the small farm sizes in most of these countries, various strategies are being applied for rapid multiplication and dissemination of resistant varieties. Approaches being used for rapid multiplication and distribution include pre-release seed multiplication whilst candidate resistant lines are being tested in National Evaluation Trials and farmers’ participatory selection approaches. Resistant varieties were already released in Bangladesh, Afghanistan, Pakistan and Egypt, and more varieties are expected to be released in 2010 in these and other countries. Our results show that some new Ug99 resistant lines have yield superiority over dominant local varieties. Activities and progress in seed multiplication, using existing and new Ug99 resistant varieties, are discussed.
- Physico-chemical characteristics and clay mineralogical composition of selected soils in arid and semi arid region of IranAuthor(s): Mirkhani, Rayehe; Roozitalab, Mohammad; Khaleghpanah, Naser; Rezaei, Najmeh; Teimouri, Saadollah (Australian Clay Minerals Society (ACMS), 2010-09-20)Date: 2010-09-20Type: Conference PaperStatus: Open accessOral Presentation in Australian Clay Mineral Conference Brisbane August 2010 This research investigates the mineralogical composition of soils in the arid and semi-arid regions of Karaj and Eshtehard, Iran. Eight soil sites were analyzed, revealing that illite and chlorite are the dominant clay minerals, originating from the parent material. Palygorskite was found in higher amounts in saline-sodic soils, particularly those developed on marl formations.
- Improving wheat stripe rust resistance in Central Asia and the Caucasus (abstract)Author(s): Ziyaev, Zafar; Sharma, Ram; Nazari, Kumarse; Morgunov, Alexey Ivanovich; Amanov, Amir; Ziyadullaev, Zokhid; Alikulov, Safar (The Borlaug Global Rust Initiative (BGRI), 2010-06-20)Date: 2010-06-20Type: PresentationStatus: Open accessOral Presentation in BGRI 2010 Technical Workshop Russia 30-31 May 2010 Wheat is the most important cereal in Central Asia (Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan and Uzbekistan) and the Caucasus (Armenia, Azerbaijan and Georgia). Stripe rust, caused by Puccinia striiformis f. sp. tritici is considered the most important disease of wheat in Central Asia and the Caucasus (CAC). Although stripe rust has been present in the region for long time, it has become a serious constraint to wheat production in the past 10 years. This is reflected by the occurrence of four epidemics of stripe rust in the CAC region since 1999, the most recent in 2009. Several wheat varieties occupying substantial areas are either susceptible to stripe rust or possess a low level of resistance. Information on the stripe rust pathogen in terms of prevalent races and epidemiology is not readily available. Furthermore, there is an insufficient understanding of effective stripe rust resistance genes in the region, and little is known about the resistance genes present in the commercial varieties and advanced breeding lines. The deployment of resistant varieties is further complicated by putative changes in virulence in the pathogen population in different parts of the CAC. Many improved wheat lines received through international nurseries or other exchange programs have shown high levels of resistance to stripe rust, leaf rust and powdery mildew to local pathogen populations. It is anticipated that this germplasm will play an important role in developing stripe rust resistant wheat varieties either through direct adoption or using them as parents in breeding programs.
