    Towards drought impact-based forecasting in a multi-hazard context
    (Elsevier, 2022-01-26) Boult, Victoria L.; Black, Emily; Abdillahi, Halima Saado; Bailey, Meghan; Harris, Clare; Kilavi, Mary; Kniveton, Dominic; MacLeod, David; Mwangi, Emmah; Otieno, George; Rees, Elizabeth; Rowhani, Pedram; Taylor, Olivia; Todd, Martin C.
    The lives and livelihoods of people around the world are increasingly threatened by climate related risks as climate change increases the frequency and severity of high-impact weather. In turn, the risk of multiple hazards occurring simultaneously grows and compound impacts become more likely. The World Meteorological Organization (WMO) proposed the use of multi-hazard impact-based forecasting (IbF) to better anticipate and reduce the impacts of concurrent hazards, but as yet, there are few operational examples in the humanitarian sector. Drought is particularly susceptible to multi-hazard influences. However, challenges encountered in the development of drought IbF systems – including poor understanding of compound impacts and specific hazard-focused mandates – raise important questions for the feasibility of multi-hazard IbF as envisioned by the WMO. With these challenges in mind, we propose an interim approach in which real-time assessment of dynamic vulnerability provides a context for drought-based IbF. The incorporation of dynamic vulnerability indicators account for the local effects of non-drought hazards, whilst the use of a drought-based system facilitates effective intervention. The proposed approach will improve our understanding of compound events, enhance adoption of IbF in the humanitarian sector, and better mitigate the impacts of concurrent hazards.

    Determinants of Household Willingness to Pay for Improved Water Supply: A Case Study of Baringo and Samburu Counties, Kenya
    (Researchgate, 2020-09) Kingori, Sarah; Abdillahi, Halima Saado
    Background: In Sub-Saharan Africa, the supply of affordable, accessible and safe drinking water particularly in rural areas lags behind global progress. Achieving the universal and equitable access objectives warrants an understanding of household behavior in relation to water services. Purpose of the study: The aim of the study was to investigate the factors that influence willingness to pay for improved water service provision in a rural context in Kenya. Methods: A total of 601 households in Baringo and Samburu Counties were randomly selected using probability proportional to size technique. The data was analyzed using descriptive statistics and logit regression. Results: The empirical result shows that demographic characteristics of household, water source, quality and quantity, children responsible for fetching water, water access challenges and frequency of diarrhea are significant variables that explain willingness to pay. Conclusion: The findings conclude with important policy recommendations; (i) demand-driven approaches in the design of water supply projects, (ii) enhanced water quality management, and (iii) awareness creation to achieve social and health benefits which can facilitate long-term access and sustainability.

    Use of earth observation products to enhance humanitarian disaster response: A Case Study of KRCS Response to West Pokot Mudslides in 2019
    (Researchgate, 2020-12-01) Osunga, Michael; Makena, Betty; Abdillahi, Halima Saado
    Kenya is mostly affected by mudslides and floods during two rainfall seasons, namely March-April-May (MAM) and October-November-December (OND). These landslides, floods and mudslides more often than not lead to loss of human lives, destruction of houses, displacement of people, livestock deaths, loss livelihoods among other impacts. This paper highlights the use of earth observation satellite imageries from the Airbus foundation for-disaster impact assessment during the 2019 OND rainfall season to support effective response. On the 23rd of November 2019 during the OND rainfall season, mudslides and floods occurred in West Pokot resulting in disruption of road accessibility, loss of human lives, loss of livelihoods, houses destruction and displacement of people. Due to continuation of rainfall, roads were cut-off and hence it was difficult to access the area to determine the damage and the number of households affected. Through the partnership with Airbus foundation, International Center for Humanitarian Affairs (ICHA) at Kenya Red Cross Society (KRCS) tasked the Pleiades satellite to acquire imageries of the affected areas five days after the mudslide event. A spot 6 imagery archive captured on the 15th of May 2019 (months before the mudslide event) was downloaded from the Airbus foundation archives. A comparison of these two imageries through change detection was done in order to extract mudslide and flooding hazard extents. A hazard exposure analysis was done in order to determine houses and roads affected by the mudslide and flood hazard. Results from exposure analysis revealed over 145 houses as being destroyed and over 2.1 kilometers of roads being cut-off. Further analysis was done to determine partially and completely destroyed houses. KRCS was able to use this information for post-disaster recovery interventions such as search and rescue as well as shelter initiation of re-construction houses that were completely damaged by floods and mudslides. This study has demonstrated the valuable use of satellite imageries from the Airbus Foundation to KRCS through provision of timely and accurate information on impacts of mudslides and floods in remote and inaccessible areas in a cost-effective manner and further support effective and efficient response and recovery. It is highly recommended for KRCS and other Red Cross and Red Crescent National Societies to use earth observation satellites for post-disaster assessment especially in remote areas that are inaccessible. This by far would improve their humanitarian capacity in conducting post-disaster assessments in a cost-effective and timely manner.
