“…However, underlying mechanism of occurrence of the disease is comparable to spring cholera outbreaks in delta. As noted by Collins et al (2006), majority of cholera in Mozambique is initiated along the coasts and then propagated inlands through secondary means. Here the objective was to apply the proposed methodology on Mozambique cholera data and to show applicability of SWM over a different endemic region.…”

“…Here the objective was to apply the proposed methodology on Mozambique cholera data and to show applicability of SWM over a different endemic region. The analysis on hydroclimatic controls on Mozambique cholera is presented elsewhere (Collins et al 2006; Jutla et al 2010). A seasonal peak in the coastal region of Maputo occurs in the months of December-January-February or winter season (Jutla et al 2010).…”

The ability to predict an occurrence of cholera, a water-related disease, offers a significant public health advantage. Satellite based estimates of chlorophyll, a surrogate for plankton abundance, have been linked to cholera incidence. However, cholera bacteria can survive under a variety of coastal ecological conditions, thus constraining the predictive ability of the chlorophyll, since it provides only an estimate of greenness of seawater. Here, a new remote sensing based index is proposed: Satellite Water Marker (SWM), which estimates condition of coastal water, based on observed variability in the difference between blue (412 nm) and green (555 nm) wavelengths that can be related to seasonal cholera incidence. The index is bounded between physically separable wavelengths for relatively clear (blue) and turbid (green) water. Using SWM, prediction of cholera with reasonable accuracy, with at least two month in advance, can potentially be achieved in the endemic coastal regions.

“…The research tools and engagement processes varied depending on the identified demand for risk reduction for survivability and well-being. An infectious disease risk reduction project in Mozambique and Bangladesh involving tens of thousands of people caught up in epidemics progressed through integrating community driven infectious disease risk monitoring alongside adapted community and government led responses (Collins et al 2006;Williams et al 2010). A further example was borne out by a community driven natural resources risk mitigation and development project in the upper Zambezi region of Zimbabwe.…”

Consolidation of disaster and development studies as an integrated field of action research that influences policy has proved to be fundamental to global disaster risk reduction, sustainable development, climate change, and humanitarian agreements. However, challenges in achieving targets, such as those of the Sendai Framework for Disaster Risk Reduction 2015-2030 and the Sustainable Development Goals, requires further advances of the disaster and development paradigm underpinning these aspirations. This article presents perspectives that grew primarily from local action research, particularly research carried out with marginalized and highly at-risk groups of people in Southern Africa and South Asia. Analytical fronts from these findings emphasize disaster and development risk assessment opportunities that consolidate earlier ideas and extend understanding of disaster and development-related risk intervention options. These acknowledge severe shortcomings in disaster risk reduction progress while including greater use of hope as an active ingredient. This process of paradigm exploration remains fundamental to achieving disaster risk reduction, sustainable development, and associated policy objectives. The analysis presented here reiterates earlier groundings in people-centric perspectives, emphasizing social relations and systems of meaning as essential active ingredients for challenging power structures, technology, education, and human behavior. The analysis proposes some consequent thematic fronts for increased investment. These include investing in early buildup of well-being before a disaster, better living with uncertainty, and overcoming the barriers to desired disaster and development outcomes. The article is intended to contribute to an ever-evolving paradigm of disaster and development risk that requires impetus from personal and collective values beyond calculations of disaster and development.

“…In our view, the deteriorating cholera situation is largely due to the pervasively poor socioeconomic development, which continues to fuel inequitable distribution and access to the social services that determine health outcomes such as water, sanitation, education, good housing, and healthcare on the continent. [26][27][28][29] A good example is the 2008/2009 cholera outbreak in Zimbabwe, which occurred within the context of a socioeconomic crisis in the country, resulting in the breakdown of the aging water and sanitation system of the country's capital Health Services Insights city of Harare. 30 This observation is corroborated by Talavera and Perez who demonstrated that cholera affects low-income countries more than countries with middle or high-income.…”

Seven years to the Global Taskforce on Cholera Control’s target of reducing cholera cases and deaths by 90% by 2030, Africa continues to experience a high incidence of the disease. In the last 20 years, more than 2.6 million cases and 60 000 deaths of the disease have been recorded, mostly in sub-Saharan Africa. Case Fatality Ratio remains consistently above the WHO-recommended 1% with a yearly average of 2.2%. Between 1 January 2022 and 16 July 2023, fourteen African countries reported 213 443 cases and 3951 deaths (CFR, 1.9%) of the disease. In this perspective article, based on available literature and the authors’ field experiences in Africa, we discuss the underlying reasons for the sustained transmission of the disease. We posit that in addition to the well-known risk factors for the disease, the chronic cholera situation in Africa is due to the poor socioeconomic development status, weak household and community resilience, low literacy levels, weak capacity of African countries to implement the 2005 International Health Regulation and the pervasively weak health system on the continent. Stemming this tide requires good leadership, partnership, political commitment, and equity in access to health services, water, and sanitation. Therefore, we recommend that African governments and stakeholders recognize and approach cholera prevention and control from the long-term development lens and leverage the current cholera emergency preparedness and response efforts on the continent to strengthen the affected countries’ health, water, and sanitation systems. We call on international organizations such as WHO and the Africa Centres for Diseases Control to support African governments in scaling up research and innovations aimed at better characterizing the epidemiology of cholera and developing evidence-based, context-specific, and innovative strategies for its prevention and control. These recommendations require long-term multisectoral and multidisciplinary approaches.
