The Archive Appetizer: Climate services servicing nutrition

The Archive Appetizer is a short musing on a topic, distinct from our longer regular blogs and monthly Food Bytes posts. Let’s get started.

Since coming back to Columbia, some of our research has taken on a new focus of climate services. What exactly are climate services? I like this definition published by the Climate Service Journal (it seems like a legitimate source, in my opinion). They define climate services as:

“The transformation of climate-related data (from the past, present or future) - together with other relevant information - into customized products such as projections, forecasts, information, trends, economic analysis, assessments (including technology assessment), counselling on best practices development and evaluation of solutions and any other services in relation to climate that may be use for the society at large.”

How climate services are generated, translated, transferred and used.

Climate change and climate-related extreme events have multiple negative effects on global public health including food insecurity, infectious disease burden, malnutrition, and diet-related non-communicable diseases. Today, there is a growing recognition that public health and nutrition practitioners (PHNPs) need access to climate services to be better equipped and tackle more effectively the complex health challenges of climate disruption for the populations they serve. However, evidence suggests that local PHNPs rarely use climate services efficiently or effectively to prevent malnutrition and provide better health care to the populations in which they serve. This is a critical gap, as these PHNPs are responsible for designing and implementing health-nutrition program interventions when and where they are most needed.

We have started a project that is designed to address this gap directly. In this project, we posit that targeted climate services that focus more intentionally on improving nutrition and health programming have the potential to lead to even more significant improvements in health outcomes. Bringing together a transdisciplinary team of climate and public health, nutrition, and policy experts, the project will be conducted in Ethiopia and Indonesia, where multiple forms of malnutrition and infectious disease are endemic and where risks of climate stress are recognized and well documented.

Stay tuned….

Climate-resilient communities are nutrition-resilient communities

This piece was originally published as a commentary in Nature Climate Change.

Climate change and nutrition are closely interconnected. Climate variability, which includes year-on-year variations in climate and longer-term climate trends, can disrupt both health and food systems, leading to increased food insecurity, reduced access to quality diets, and worsened burdens of malnutrition, particularly for vulnerable populations, including women and children.

While the 2021 UN Food Systems Summit made some advancements in integrating climate change actions into food system transformations, nutrition, more specifically, is still not mainstreamed into the larger climate change agenda or global commitments made at the annual global COP meetings. At the same time, the field of nutrition has yet to fully consider climate-responsive adaptation strategies in its core policy and programming.

One first step towards more engagement between climate and nutrition communities is for climate scientists to provide climate information (such as weather and climate variability forecasts and projections) to health practitioners delivering nutrition interventions through the public health sector. By providing them with information that is easy to understand and use, practitioners will be better equipped to tackle the complex health challenges that come with climate disruptions for the populations they serve.

It is unclear how local nutrition practitioners use climate information in their day-to-day decision-making. Understanding this uncertainty is critical, as these practitioners are responsible for targeting health–nutrition program interventions where and when they are most needed, including reaching the most vulnerable populations in resource-constrained settings. Such climate information includes

(1) risk assessments for better targeting of actions,

(2) early warnings of extreme events, and

(3) long-term planning and preparedness to improve the design of short- and long-term adaptation strategies that target timely nutrition interventions throughout the health system.

Some examples of cost-effective interventions that aid the public health sector in adapting to climate variability and change include stockpiling supplements and therapeutic foods to treat acute malnutrition and prioritizing the management of infectious disease treatments that ultimately impact nutrition outcomes (that is, deworming medicines, materials, and oral rehydration salts). In addition, ministries of health can leverage climate information for planning and preparedness, such as strengthening capacity, resources, and infrastructure to assist communities in adapting better to near- and long-term events. Last, timely digital technology of early warning systems (that is, climate forecasting information) should be scaled up and reach communities disproportionately impacted by climate change. These technologies should complement the outreach of community health workers to ensure that households have fundamental services such as access to an environment that enables breastfeeding, clean drinking water, and safe, sufficient, and diverse foods.

Equipping public health nutrition practitioners with knowledge, confidence, and motivation to incorporate climate information into their daily work has multiple benefits. First, the climate science community can better respond to health system needs by co-generating and co-translating climate information that is understandable and actionable and ultimately supports climate adaptation and resilience. Second, better use of this climate information will ensure that health practitioners have the skills and abilities to construct public health nutrition programs that are more climate resilient. Last, with more targeted programs, nutritional needs can be better prioritized and served among communities coping with and adapting to a changing climate.
