Climate Changes Many Things Including Malaria

Heavy rains, flooding and malaria A changing climate, even a warming climate, does not directly translate into greater malaria transmission.[i] Lafferty and Mordecai explain that we need a need “a greater appreciation for the economic and environmental factors driving infectious diseases,” as these have their own impact on transmission.[ii] Climate change effects occur in parallel to “changes such as land conversion, urbanization, species assemblages, host movement, and demography.” This wider ecological understanding is needed to “predict which diseases are most likely to emerge where, so that public health agencies can best direct limited disease control resources.” As the WHO framework for malaria elimination stresses, [iii] “Most countries have diverse transmission intensity, and factors such as ecology, immunity, vector behaviour, social factors and health system characteristics influence both the diversity of transmission and the effectiveness of tools, intervention packages and strategies in each locality.”8 The Framework goes further to encourage strategic planning and interventions appropriate for the diverse settings or strata within a country. What climate change implies is that the nature of malaria transmission in these strata will change as temperature, rainfall, humidity and human response change. Countries not only need to adapt malaria activities to existing strata, but also be alert to changes in transmission and thus changes needed in strategies. Increased or decreased vector control activities would be one example of changes that are needed in response to climate, vector habitat and transmission changes. “The receptivity of an area (to vector control interventions) is not static but is affected by determinants such as environmental and climate factors.” Case detection will become even more crucial as transmission drops and the success of elimination programs depends on identifying, tracing and responding to remaining cases promptly and accurately.

The rise of neglected tropical diseases in the "new Texas"

by Peter J. Hotez Within the last five years, the State of Texas has experienced either transmission or outbreaks of Ebola, chikungunya, West Nile, and Zika virus infections. Autochthonous transmission of neglected parasitic and bacterial diseases has also become increasingly reported

The eternal opportunity

The new Secretary of State for International Development has been quick off the mark with positive messages about aid.  And yesterday, she added her name to the role-call of pronouncements about the power of the current generation to eradicate poverty: Thanks to technology, we have opportunities that previous generations did not. We have the power to eradicate poverty. Penny Mordaunt, Secretary of State for International Development, 30 November 2017 This is, of course, not the first time we have told ourselves this. Here are some previous examples: This is the best story in the world today — these projections show us that we are the first generation in human history that can end extreme poverty … This new forecast of poverty falling into the single digits should give us new momentum and help us focus even more clearly on the most effective strategies to end extreme poverty

Is Improving Global Public Health Compatible with Saving the Climate? Exploring the Discourses…

Mari Grepstad and Berit Sofie Hembre The climate change discourse holds that burning of fossil fuels leads to climate change. Therefore, emissions must be reduced in order to avoid climate change. Further, it holds that climate change deteriorates global public health. Acting on climate change is thought to prevent negative health outcomes.

Re: ‘The environmental impact of obesity: longitudinal evidence from the United States’

This letter serves to affirm the stance and the evidence presented in the recent article by Squalli, entitled: “The environmental impact of obesity: longitudinal evidence from the United States”.1 The said paper adds weight to the notion that two of the greatest threats facing contemporary society are climate change and the rise in non-communicable diseases, including obesity.2 Further, this article highlights that individual behaviors and health outcomes can have global consequences.

Apply Now: $500,000 for Your Big Data Innovations in Agriculture

The rapid growth in processing power and global connectivity means we can now quickly collect, share and analyze enormous amounts of data to reveal new ways to reduce hunger and poverty and develop robust responses to climate change, disease, and land degradation challenges. The CGIAR Platform for Big Data in Agriculture seeks approaches that show the power of big data analytics and digital technologies to push the limits of the possible in research, transform how we do business, and drive impact in four broad challenge areas: Revealing Food Systems Monitoring Pests and Diseases Disrupting Impact Assessment Empowering Data-Driven Farming We are challenging partners, universities, and others to use our data to create incentivized pilot opportunities that scale. We’re looking for novel approaches that democratize these data-driven insights to inform local, national, regional, and global policies on agriculture and food security in real time; helping people – especially smallholder farmers – to lead happier and healthier lives. The Prize Five winning teams will receive $100,000 each to put their ideas into practice. Teams will have 12 months to implement small-scale proof of concept pilots to demonstrate viability

Research into Use: how can Climate Change Researchers have more Impact?

Following on the recent kerfuffle about ‘research impact’ (see original and follow up posts), I spent some time chatting to climate researchers in Cape Town about ‘research into use’ (RiU, basically the same thing). The researchers are part of ASSAR, a consortium (of which Oxfam is a member) working across Africa and India with a big focus (30% of its project weighting) on RiU. Feel …

Climate change and sugarcane expansion increase Hantavirus infection risk

by Paula Ribeiro Prist, María Uriarte, Katia Fernandes, Jean Paul Metzger Hantavirus Cardiopulmonary Syndrome (HCPS) is a disease caused by Hantavirus, which is highly virulent for humans. High temperatures and conversion of native vegetation to agriculture, particularly sugarcane cultivation can alter abundance of rodent generalist species that serve as the principal reservoir host for HCPS, but our understanding of the compound effects of land use and climate on HCPS incidence remains limited, particularly in tropical regions. Here we rely on a Bayesian model to fill this research gap and to predict the effects of sugarcane expansion and expected changes in temperature on Hantavirus infection risk in the state of São Paulo, Brazil

How will we know if the SDGs are having any impact?

As long time readers of the blog will know, I’ve been a Sustainable Development Goal (SDG) sceptic since long before they were even agreed. However, I’ve been hearing a fair amount about them recently – people telling me that governments North and South, companies and city administrations are using them to frame public commitments and planning and reporting against them. So maybe it’s time to …
