International conventions acknowledge the right of refugees and of disabled people to access quality inclusive education. Both groups struggle to assert this right, particularly in the Global South, where educational access may be hindered by system constraints, resource limitations and negative attitudes. Our concern is the intersectional and compounding effect of being a disabled refugee in Sub-Saharan Africa. Disabled refugees have been invisible in policy and service provision, reliable data is very limited, and there has been little research into their experiences of educational inclusion and exclusion. This article makes the case for research to address this gap. Three country contexts (South Africa, Zimbabwe, and Uganda) are presented to illustrate the multilayered barriers and challenges to realizing the rights for disabled refugees in educational policy and practice. These three countries host refugees who have fled civil unrest and military conflict, economic collapse and natural disaster, and all have signed the United Nations Convention on the Rights of Persons with Disabilities. None has available and reliable data about the numbers of disabled refugees, and there is no published research about their access to education. Arguing for an inclusive and intersectional approach and for the importance of place and history, we illustrate the complexity of the challenge. This complexity demands conceptual resources that account for several iterative and mutually constituting factors that may enable or constrain access to education. These include legislation and policy, bureaucracy and resource capacity, schools and educational institutions, and community beliefs and attitudes. We conclude with a call for accurate data to inform policy and enable monitoring and evaluation. We advocate for the realization of the right to education for disabled refugee students and progress toward the realization of quality inclusive education for all.
The effect of salt (NaCl) on <em>Anopheles gambiae sensu lato</em> (s.l.) mosquito larval breeding was ascertained under laboratory conditions. No larval mortality occurred when the Cl– concentrations were between 0.017 ppt (0.03 ppt salinity) and 7.371 ppt (13.25 ppt salinity). However, 9%, 24%, 73.5%, 91.5% and 99.5% larval mortality occurred at 10.828 ppt (19.49 ppt salinity), 16.069 ppt (28.95 ppt salinity), 18.739 ppt (33.77 ppt salinity), 32.587 ppt (58.82 ppt salinity) and 47.326 ppt (85.37 ppt salinity) NaCl concentrations respectively. The lower NaCl concentrations resulting in LC50, (lethal concentration for 50% larval mortality), LC90 (lethal concentration for 90% larval mortality), LC95 (lethal concentration for 95% larval mortality), and LC99 (lethal concentration for 99% larval mortality) were 23.12 ppt (41.19 ppt salinity), 24.91 ppt (44.42 ppt salinity), 27.76 ppt (49.56 ppt salinity) and 33.87 ppt (60.568 ppt salinity) respectively. The upper NaCl concentration resulting in LC50, LC90, LC95 and LC99 were 32.89 ppt (58.83 ppt salinity), 37.21 ppt (66.63 ppt salinity), 44.79 ppt (80.32 ppt salinity) and 63.76 ppt (114.55 ppt salinity) respectively. In conclusion, the level of water salinity may indicate the presence or absence of<em> An. gambiae</em> s.l. mosquito larvae and this information can be used for disease control purposes.
The knock down and insecticidal effects of the plants Tagetes minuta, Lippia javanica, Lantana camara, Tagetes erecta and Eucalyptus grandis were evaluated against Anopheles arabiensis mosquitoes in thatched round huts in Mumurwi village. Leaves from these plants were smouldered in order to provide mosquito repellent smoke. Complete knock down was provided 40 minutes after mosquitoes were exposed to smoke of T. erecta, 60 minutes to smoke of T. minuta and E. grandis and 120 minutes to smoke of L. javanica. Complete knock down of mosquitoes could not be provided by L. camara within the 140-minute exposure period. The KT50 (time required to knock down 50% of the mosquitoes) values were 24.985 minutes (T. minuta), 34.473 minutes (T. erecta), 59.119 minutes (L. javanica), 59.828 minutes (L. camara) and 25.245 minutes (E. grandis). The KT90 (time required to knock down 90% of the mosquitoes) values were 48.060 minutes (T. minuta), 50.169 minutes (T. erecta), 178.341 minutes (L. javanica), 140.220 minutes (L. camara) and 47.998 minutes (E. grandis). Mortality rates 24h after exposure were 40% (T. minuta), 100% (T. erecta), 75% (L. javanica), 90% (L. camara) and 100% (E. grandis). In conclusion, smoke from the plants T. erecta, T. minuta and E. grandis had very fast knock down rates with T. erecta, L. camara and E. grandis killing over 90% of the An. arabiensis mosquitoes. Plant smoke is important in mosquito control.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
