Innovative games and role-playing help West African farmers grapple with climate change

Building new climate knowledge to support the agricultural sector has been a key FCFA focus. Using novel research processes, such as the Plateau Game, FCFA is better able to understand how farmers in West Africa make agricultural and land management decisions, and how climate events influence their decision making. Another innovate approach used in Senegal’s agricultural sector was a participatory theatre forum. African and European FCFA researchers teamed up with a troupe of West African actors to put on a theatre production for a very specific audience: farmers, local and regional government representatives with an agricultural portfolio, and civil society.

Mapping the invisible atmospheric ‘rivers’ that bring East Africa’s rain

East Africa’s rainfall depends on water vapor moving through the lower atmosphere from the Indian Ocean into the continental interior as far away as the Congo River Basin. When the jet streams that drive this water flow more swiftly, this often results in drought conditions over countries like Tanzania and Kenya. This system’s influence may even stretch as far south as Mozambique.

How has Future Climate for Africa improved the understanding of climate change in Africa?

A new micro-site on FCFA’s impact and relevance aims to highlight and signpost the impact of FCFA through three key pillars. Pillar 1 focuses on how FCFA has delivered a step change in climate science through improved understanding of what drives Africa’s climate and how it will change. Pillar 2 outlines FCFA’s novel approaches to research and engagement with government decision-makers, communities and researchers. Pillar 3 highlights how this climate information was used to address real world problems and inform development plans.

Climate variability affects water-energy-food infrastructure performance in East Africa

March 15, 2021

The need to assess major infrastructure performance under a changing climate is widely recognized yet rarely practiced, particularly in rapidly growing African economies. Here, we consider high-stakes investments across the water, energy, and food sectors for two major river basins in a climate transition zone in Africa. We integrate detailed interpretation of observed and modeled climate-system behavior with hydrological modeling and decision-relevant performance metrics. For the Rufiji River in Tanzania, projected risks for the mid-21^st century are similar to those of the present day, but for the Lake Malawi-Shire River, future risk exceeds that experienced during the 20^th century. In both basins a repeat of an early-20^th century multi-year drought would challenge the viability of proposed infrastructure. A long view, which emphasizes past and future changes in variability, set within a broader context of climate-information interpretation and decision making, is crucial for screening the risk to infrastructure.

Convection permitting regional climate change simulations for understanding future climate and informing decision making in Africa

February 23, 2021

Pan-Africa convection-permitting regional climate model simulations have been performed to study the impact of high resolution and the explicit representation of atmospheric moist convection on the present and future climate of Africa. These unique simulations have allowed European and African climate scientists to understand the critical role that the representation of convection plays in the ability of a contemporary climate model to capture climate and climate change, including many impact relevant aspects such as rainfall variability and extremes. There are significant improvements in not only the small-scale characteristics of rainfall such as its intensity and diurnal cycle, but also in the large-scale circulation. Similarly effects of explicit convection affect not only projected changes in rainfall extremes, dry-spells and high winds, but also continental-scale circulation and regional rainfall accumulations. The physics underlying such differences are in many cases expected to be relevant to all models that use parameterized convection. In some cases physical understanding of small-scale change mean that we can provide regional decision makers with new scales of information across a range of sectors. We demonstrate the potential value of these simulations both as scientific tools to increase climate process understanding and, when used with other models, for direct user applications. We describe how these ground-breaking simulations have been achieved under the UK Government’s Future Climate for Africa Programme. We anticipate a growing number of such simulations, which we advocate should become a routine component of climate projection, and encourage international co-ordination of such computationally, and human-resource expensive simulations as effectively as possible.

Technical Brief: Climate change impacts – implications for policy and practice in Tanzania’s Rufiji River Basin

February 17, 2021

This brief synthesises the results of undertaking a climate risk analysis for the Rufiji River Basin, Tanzania. The basin supports extensive socio-economic and environmental services and is targeted for major development via hydropower infrastructure and investment through the Southern Agricultural Growth Corridor of Tanzania. The implications of climate risk for development objectives that cut across the water-energy-food-environment sectors are outlined and recommendations proposed to help achieve climate resilient sustainable development.

The brief is for practitioners and technical policy-makers with a detailed interest in understanding development processes and the impacts of climate change in the Rufiji River Basin. The approach is relevant for other large river basins undergoing rapid development.

Climate services in Africa: Re-imagining an inclusive, robust and sustainable service

February 12, 2021

Africa is one of the most vulnerable continents to climate change because of its heightened sensitivity to climate variability and inadequate institutional adaptive capacity. Notwithstanding these challenges, Africa, and its inhabitants, have been confronting the vagaries of climate for centuries, including severe droughts and floods. Given this context, this paper provides a commentary on the efforts to ensure and enable climate services on the continent as well as a critical, reflexive assessment of activities in this varied landscape. A special focus on the institutional frameworks and the underlying knowledge systems that support and interface with climate services will be examined. A central question underpinning the paper is: to what extent is the expanding landscape of climate services being endogenously driven in Africa? Finally, some recommendations for future efforts to enhance effective institutions and knowledge brokering and facilitate better climate services in Africa are suggested.

In-situ fluorescence spectroscopy indicates total bacterial abundance and dissolved organic carbon

February 11, 2021

We explore in-situ fluorescence spectroscopy as an instantaneous indicator of total bacterial abundance and faecal contamination in drinking water. Eighty-four samples were collected outside of the recharge season from groundwater-derived water sources in Dakar, Senegal. Samples were analysed for tryptophan-like (TLF) and humic-like (HLF) fluorescence in-situ, total bacterial cells by flow cytometry, and potential indicators of faecal contamination such as thermotolerant coliforms (TTCs), nitrate, and in a subset of 22 samples, dissolved organic carbon (DOC). Significant single-predictor linear regression models demonstrated that total bacterial cells were the most effective predictor of TLF, followed by on-site sanitation density; TTCs were not a significant predictor. An optimum multiple-predictor model of TLF incorporated total bacterial cells, nitrate, nitrite, on-site sanitation density, and sulphate (r² 0.68). HLF was similarly related to the same parameters as TLF, with total bacterial cells being the best correlated (ρ_s 0.64). In the subset of 22 sources, DOC clustered with TLF, HLF, and total bacterial cells, and a linear regression model demonstrated HLF was the best predictor of DOC (r² 0.84). The intergranular nature of the aquifer, timing of the study, and/or non-uniqueness of the signal to TTCs can explain the significant associations between TLF/HLF and indicators of faecal contamination such as on-site sanitation density and nutrients but not TTCs. The bacterial population that relates to TLF/HLF is likely to be a subsurface community that develops in-situ based on the availability of organic matter originating from faecal sources. In-situ fluorescence spectroscopy instantly indicates a drinking water source is impacted by faecal contamination but it remains unclear how that relates specifically to microbial risk in this setting.

Tryptophan-like and humic-like fluorophores are extracellular in groundwater: implications as real-time faecal indicators

February 11, 2021

Fluorescent natural organic matter at tryptophan-like (TLF) and humic-like fluorescence (HLF) peaks is associated with the presence and enumeration of faecal indicator bacteria in groundwater. We hypothesise, however, that it is predominantly extracellular material that fluoresces at these wavelengths, not bacterial cells. We quantified total (unfiltered) and extracellular (filtered at < 0.22 µm) TLF and HLF in 140 groundwater sources across a range of urban population densities in Kenya, Malawi, Senegal, and Uganda. Where changes in fluorescence occurred following filtration they were correlated with potential controlling variables. A significant reduction in TLF following filtration (ΔTLF) was observed across the entire dataset, although the majority of the signal remained and thus considered extracellular (median 96.9%). ΔTLF was only significant in more urbanised study areas where TLF was greatest. Beneath Dakar, Senegal, ΔTLF was significantly correlated to total bacterial cells (ρ_s 0.51). No significant change in HLF following filtration across all data indicates these fluorophores are extracellular. Our results suggest that TLF and HLF are more mobile than faecal indicator bacteria and larger pathogens in groundwater, as the predominantly extracellular fluorophores are less prone to straining. Consequently, TLF/HLF are more precautionary indicators of microbial risks than faecal indicator bacteria in groundwater-derived drinking water.
