“…In such regions, agrivoltaics could increase the resilience of communities against climate change impacts such as unpredictable precipitation patterns, increased drought events and extreme heat; this is due to the improved water use efficiency and reduced heat stress for crops grown under agrivoltaic systems 25,45,55,56 . Indeed, the two districts highlighted as most suitable for agrivoltaics for marginal farming -Bahi and Chamwino in Tanzania -are both semi-arid, drought prone, and expected to progressively suffer from heat and rainfall variability 57 . Implementing agrivoltaics in these locations could therefore be a vital adaptation strategy to combat the adverse effects of climate change.…”

Agrivoltaics address energy, food, and water security concomitantly, yet little research has addressed the opportunities and barriers for this technology in East Africa, a region facing substantial challenges across the water-energy-food nexus. Here, we identify possible use cases for the technology in five East African nations and determine the factors influencing delivery of potential benefits, before assessing the spatial suitability of the technology for two of the emergent use cases: agribusiness and marginal farming. Our findings show there is a moderate to high suitability for AV across both use cases, with a range of biophysical and social factors driving successful outputs; land tenure and solar radiation were the most important for determining suitability. Our analysis indicates where AVs would be best developed to improve access to, and resilience of, energy and food production in East Africa, and our methods could be applied to other locations to support agrivoltaics development internationally.

“…Similar findings have emerged from other semi-arid regions in Tanzania. For instance, trend analysis from the Dodoma station (Myeya 2021), covering the period from 1961 to 2013, revealed an upward yet statistically insignificant trend in temperature and rainfall, with a marginal increase of 0.3% in rainfall over 53 years. Similarly, predictions from Iyamuremye et al ( 2019) indicate a future rise in maximum rainfall in Dodoma.…”

This study investigates the impact of climate change on rainfall and temperature dynamics in Bahi and Mpwapwa Districts , Dodoma Region, Tanzania , over 41 years (1981–2021). The study used historical temperature and precipitation data from the Tanzania Meteorological Authority (TMA). The dataset was analyzed using linear regression and the Mann -Kendall trend test using MS Excel (2010) and SPSS V20. The results indicate slight increases in annual rainfall in Mpwapwa (3.717mm) and Bahi (2.743mm). However, mean decadal precipitation analysis reveals that Mpwapwa experienced a decrease in rainfall during the first three decades , followed by a significant increase in the most recent ten years . Conversely, the amount of rainfall in Bahi remained relatively consistent throughout, except for the last ten years, when there was an increase in precipitation compared to the earlier decade . However , the Mpwapwa district is observing an increase in the number of rainy days, whereas Bahi is experiencing a decrease. Additionally , both districts have encountered a notable rise in both minimum and maximum temperatures . These changes , particularly the increase in temperature and fluctuating rainfall , significantly impact agro-pastoral communities in these semi-arid regions . The study underscores the need for these communities to implement stronger adaptation strategies to mitigate the adverse effects of rising temperatures and changing rainfall patterns.

“…Mpwapwa is 120 km away from Dodoma City. The district is located between latitudes 6º 00ꞌꞌ and 7º 00ꞌꞌ S and longitudes 35º 45ꞌꞌ and 37º 00ꞌꞌ E. The district is reasonably arid with total rainfall of 753.5 mm and temperature range of 17ºC and 29ºC (Myeya, 2021). According to the 2012 National Census, the population of Mpwapwa District was 305,056 people (National Bureau of Statistics, 2013).…”

Woodlands are important sinks for the ever increasing levels of atmospheric carbon dioxide, which is directly linked to climate change. Baobab (Adansonia digitata L.) is among the vascular tree species with a long lifespan of 1250 years thus potential for carbon storage though inadequately studied. This study therefore aimed to account for aboveground biomass and carbon in an agroforestry of Mkanana village (with baobabs and sunflower) and Mangalisa forest reserve in Mpwawa District. The allometric model developed for baobabs in dry areas was used for estimation of biomass which was computed as 50% carbon. The mean aboveground biomass of baobabs of 6.952 ± 0.09546 tonnes/tree in Mangalisa forest reserve was higher than 5.538 ± 0.3064 tonnes/tree recorded in Mkanana agroforestry (Mann-Whitney U-Statistic = 94.000, U’ = 531.00, P ˂ 0.0001). On the other hand, the mean aboveground carbon of 3.476 ± 0.09546 tonnes/tree in Mangalisa forest reserve was significantly higher than 2.769 ± 0.1533 tonnes/tree recorded in Mkanana agroforestry (Mann-Whitney U-Statistic = 93.000, U’ = 532.00, P ˂ 0.0001). The results of this study positively contribute to vegetation carbon storage. Sustainable carbon storage in baobabs can be achieved by planting them in reserve areas rather than in agroforestry.
