Health impacts of climate-change related natural disasters on persons with disabilities in developing countries: A literature review
(Elsevier Masson SAS, 2024-09) Uddin, Taslim;; Tasnim, Anika;; Islam, Md Redwanul ;; Islam, Mohammad Tariqul;; Salek, A.K.M.;; Khan, Md Moniruzzaman;; Gosney, James;; Haque, M Atiqul
Background: Climate change is identified as the foremost health threat in the present era, resulting in a broad range of negative health impacts on individuals, families, and communities. Marginalized populations in developing countries are particularly affected. This literature review explored the health impacts of climate change-related natural disasters on persons with pre-existing physical and mental disabilities in developing countries. Methods: The Joanna Briggs Institute [JBI] evidence synthesis guideline was applied and results were reported following Preferred Reporting Items for Systematic Reviews and Meta-Analyses [PRISMA] guidelines. PubMed, PsycINFO, Scopus, and Embase databases were searched using terms related to ‘persons with disabilities’ (PWD), ‘climate change’, and “developing countries” and types of natural disasters considered to result from climate change. Selected articles were reviewed and thematic analysis was performed. Findings: Fourteen articles were included of which five generalized across multiple countries and nine profiled specific developing countries including Bangladesh, China, Haiti, India, Nepal, Philippines, South Africa, Tuvalu, and Uganda. Five key themes were identified: [i] impact on PWD physical health, [ii] impact on PWD mental health, [iii] resilience and coping strategies of PWD in disasters, [iv] PWD involvement in inclusive disaster planning, and [v] climate-change related natural disasters on PWD in developing countries as a human rights issue. Interpretation: This review underscores the lack of literature related to negative health impacts of climate change-related natural disasters on persons with pre-existing physical and mental disabilities in developing countries. Additional research is required to better understand these impacts as well as contributing social and economic factors and facilitative coping and resilience strategies in climate-related natural disasters. Addressing these gaps can inform development of effective, disability-inclusive disaster management practices which contribute to more equitable climate-change related health and rights-based outcomes for PWD in developing countries.
Sustainability of farmer organizations in Uganda: the role of organizational and institutional factors
(Springer International Publishing, 2024-09) Nangobi, Racheal;; Mshenga, Patience Mlongo;; Mugonola, Basil
Abstract In Uganda, despite government support, many farmer organizations are short-lived or exist solely to receive subsidies. Existing literature evaluates the sustainability of farming systems, technology impacts, and non-certified markets, yet a gap remains regarding the sustainability of farmer organizations. This study addresses this gap by determining a sustainability index and the effect of organizational and institutional factors on the sustainability of farmer organizations in central and northern Uganda. It highlights how regional disparities impact organizational sustainability. Using cross-sectional data from 272 farmer organizations across 12 randomly selected districts, a multilevel mixed-effects linear regression in Stata13 was employed. Results indicate that Ugandan farmer organizations have a low sustainability index of 36%, with central organizations slightly outperforming northern counterparts by 2%. Significant differences exist between northern and central organizations in terms of finances, resources, value addition, training, and leadership. Additionally, internal financial dependence, leadership committee size, farm management, and value addition training greatly enhance sustainability. Specifically, regional level variables contribute 21% to changes in the sustainability of farmer organizations in Uganda. To enhance sustainability, farmer organizations should engage in income-generating activities aligned with their economic, environmental, and social welfare objectives. The government should also intensify leadership, farm management, and value addition training.
Institutional arrangements and economic analysis of the management of livestock water infrastructure investments in agro-pastoral areas of Teso and Karamoja in Uganda
(Frontiers Media S.A, 2024-09) Aseete, Paul;; Ilukor, John;; Bagamba, Fredrick ;; Lwiza, Florence;; Walusimbi, Sadhat;; Ng’andwe, Pushina Kunda;; Oryokot, Joseph;; Ndamira, Barbara Magezi;; Sebudde, Rachel K.
The study aimed to evaluate the utilization, management structures, costs, and benefits of livestock water infrastructure in the pastoral communities of the Teso and Karamoja sub-regions. Data were collected on various water infrastructures, including boreholes, valley dams, and valley tanks. The findings suggest that investing in water infrastructure is economically viable, although functionality and usage differ across regions. Water use associations (WUAs) and community volunteers predominantly managed the water infrastructure, with local governments providing oversight. In Teso, 45%–75% of water use associations were deemed functional, compared to a lower rate of 33%–40% in Karamoja. Generally, users of water infrastructure in Teso demonstrated a higher willingness to pay for various services compared to those in Karamoja. The study also found that, under the status quo, co-management and joint efforts between WUAs and volunteers could be more economically viable management structures for boreholes. Valley dams could be better managed by WUAs, while local governments, with community support, could effectively manage valley tanks. The major challenges in managing water facilities included free riding, failure to enforce regulations, the potential for ownership tragedy, inadequacies in managing technologies, and the effects of drought. The research and implications of these findings are further discussed in the study.
Assessment of Systematic Errors in Mapping Electricity Access Using Night-Time Lights: A Case Study of Rwanda and Kenya
(MDPI AG, 2024-10) Raji, Tunmise;; Taneja, Jay;; Williams, Nathaniel
Remotely sensed nighttime light data have become vital for electrification mapping in data-scarce regions. However, uncertainty persists regarding the veracity of these electrification maps. This study investigates how characteristics of electrified areas influence their detectability using nighttime lights. Utilizing a dataset comprising the locations, installation date, and electricity purchase history of thousands of electric meters and transformers from utilities in Rwanda and Kenya, we present a systematic error assessment of electrification maps produced with nighttime lights. Descriptive analysis is employed to offer empirical evidence that the likelihood of successfully identifying an electrified nighttime light pixel increases as characteristics including the time since electrification, the number of meters within a pixel, and the total annual electricity purchase of meters in a pixel increase. The performance of models trained on various temporal aggregations of nighttime light data (annual, quarterly, monthly, and daily) was compared, and it was determined that aggregation at the monthly level yielded the best results. Additionally, we investigate the transferability of electrification models across locations. Our findings reveal that models trained on data from Rwanda demonstrate strong transferability to Kenya, and vice versa, as indicated by balanced accuracies differing by less than 5% when additional data from the test location are included in the training set. Also, models developed with data from the centralized grid in East Africa were found to be useful for detecting areas electrified with off-grid systems in West Africa. This research provides valuable insight into the characterization of sources of nighttime lights and their utility for mapping electrification.
Spatio‑temporal variations in physicochemical water quality parameters of Lake Bunyonyi, Southwestern Uganda
(SN Applied Sciences, 2021) Alex, Saturday; Lyimo, Thomas J.; Machiwa, John; Siajali, Pamba
The current study was carried out to examine the spatial and temporal variations of physicochemical water quality parameters of Lake Bunyonyi. The observations were made on the surface water of Lake Bunyonyi for 1 year to determine the water quality. The basic 12 variables used to determine the quality of water were measured monthly at nine stations. Water temperature, dissolved oxygen (DO), turbidity, electric conductivity (EC), pH and Secchi depth (SD) were measured in the field, while parameters like total nitrogen (TN), total phosphorus (TP), nitrite-nitrogen (NO2-N), nitrate-nitrogen (NO3-N), soluble reactive phosphorus (SRP) were determined following APHA 2017 standard guidelines for physicochemical analysis. Taking into account standard guidelines for drinking water by the Uganda National Bureau of Standards (UNBS) and the World Health Organization (WHO), the water quality index (WQI) was used to determine the water quality. Temperature, DO, pH, turbidity and EC did not differ significantly among the study stations (p > 0.05) but showed significant temporal variations among the study months (p < 0.05). Likewise, TN, TP, NO2-N, NO3-N and SRP did not differ significantly among the study stations (p > 0.05) but showed significant temporal variations among the study months (p < 0.05). The WQI values ranged from 28.36 to 49 across and from 28.2 to 56.2 between study months with an overall mean value of 36.9. The measured water quality variables did not exceed the UNBS and WHO standards for drinking water in all months and at all stations. According to these values, the water quality of Lake Bunyonyi generally belongs to the ‘good’ class in terms of drinking water quality based on the WQI classification. The study findings are fundamentally important for policy makers in setting guidelines for effective lake management.
