“…Savanna vegetation is responsive to both short-term fluctuations in rainfall and long-term climatic patterns (Goward & Prince, 1995;Scanlon et al, 2002). However, rainfall generally decreased in the region over the past 50 years (Noufé et al, 2015;Sagna et al, 2021), and we did not detect any significant trend in rainfall in the study area between 1981 and 2021 (see time series analysis of monthly precipitation in Supplementary Information). Vegetation shifts driven by increased rainfall are therefore unlikely.…”

Tropical savannas are globally extensive and ecologically invaluable ecosystems. As most ecosystems however, they are subject to serious anthropogenic stress. Defaunation, and especially the loss of large mammals, is pervasive in tropical savannas and known to trigger wide‐ranging ecological effects, from vegetation changes to the loss of ecosystem function. Despite what is currently known about the terrestrial consequences of defaunation, and the potential cross‐ecosystem influence of large mammals, virtually no research has investigated associated effects on small adjacent water bodies. This research gap persists because (1) tropical savannas have been historically neglected, (2) the ecological value of small water bodies (e.g. ponds) is only recently being recognized, and (3) empirical baseline data are often lacking. In this paper, we compared a rare pre‐change dataset with newly collected data on 213 freshwater assemblages, to investigate community structure and composition before and after a major defaunation event. Our research focused on a diverse species assemblage of amphibian larvae (i.e. tadpoles) in temporary savanna ponds. We found that pond vegetation cover increased from 16.0% to 45.6% post‐defaunation, that is, a near three‐fold increase. Such habitat changes seemed to have benefitted those species that use vegetation during reproduction (e.g. the leaf‐folding Afrixalus spp.), while others have declined. Interestingly, we found a strong correlation between tadpole community shifts and other freshwater organisms, which indicates that habitat changes have affected a wide variety of aquatic organisms. Given that organisms inhabiting temporary aquatic habitats often have complex life histories with terrestrial adult life stages, we propose that the terrestrial effects of defaunation have indirectly led to distinct aquatic communities, in addition to direct habitat effects. These results shed new light on the potential role of large‐bodied mammals in shaping adjacent ecosystems, and raise important questions concerning the functioning of temporary aquatic systems in the Anthropocene.

“…Several pieces of literature describe the ways farmers perceive climate change, including those of Amjath-Babu et al (2017) in South Asia and South America, [20] in Benin [21] in Central Rift Valley of Ethiopia, Nwaobiala & Nottidge [22] in the Abia State of Nigeria, Mngumi [23]in Mwanga district in northern Tanzania, Toukal Assoumana et al (2016) [24] in Niger, Asayehegn et al [25]. In Kenya, Atube et al, (2021) [26] in Uganda, and Noufé et al [27] in Comoe River basin in Ivory Coast. These studies collectively indicate that farmers have observed notable shifts and alterations in climate and weather patterns.…”

This paper examines agriculturists’ perception and adaptation to climate change in Jaman South Municipality of Ghana, utilizing a mixed research approach. The study engaged 150 farmers from five farming communities, alongside 10 local agricultural extension officers. Data were collected through questionnaires and structured interviews administered via face-to-face interactions. The data underwent analysis involving calculations of frequencies, percentages, means, standard deviations, and utilization of the probit regression model. Respondents identified significant changes in rainfall patterns, including shortened planting seasons, reduced rainfall amounts, extreme dry spells, heavy rainfall, erratic patterns, and shifts in onset and cessation. Temperature changes were also reported, with increased daytime and nighttime temperatures. These changes were perceived to have adversely affected crop production in the study area. To this effect, farmers have employed diverse adaptation strategies, such as crop diversification, cover cropping, mulching, crop rotation, composting and use of organic fertilizers, adjusting planting time, land rotation, and use of drought-tolerant crop varieties to tackle these climatic changes. Age, level of education, engagement with extension services, and farmers' experience in farming emerged as the most influential factors for predicting the selection of strategies to adapt to climate change. This study contributes insights to policymakers and practitioners striving to bolster adaptive capacity in the face of climate change.

“…Le climat constitue un facteur qui régit la production agricole et sa variabilité interannuelle conditionne les systèmes socioéconomiques et environnementaux liés à la disponibilité des ressources en eau (Djamanb et al, 2016 ;Faye, 2017). Ces irrégularités pluviométriques ont pour corollaire la variabilité des dates de démarrage, de fin et de durée des saisons pluvieuses, associées à une plus grande occurrence des déficits hydriques (Noufé et al, 2015). Les pluies représentent l'élément climatique fondamental qui conditionne les différentes activités agricoles, car les fluctuations climatiques entraînent une modification des systèmes culturaux, engendrent un déficit de la balance commerciale, ébranlent le système économique et tout le tissu social (Djohy et al, 2015).…”

La production maraîchère est potentiellement affectée par les effets de la variabilité des paramètres climatiques en Afrique de l’ouest. C’est pourquoi, la présente étude s’est proposée d’analyser l’impact de la variabilité climatique sur les rendements de la tomate et du piment dans les communes de Djougou et de Tanguiéta. Elle s’est appuyé sur une analyse des tendances pluviométriques et thermométriques de 1971 à 2020 de la zone d’étude et les test statistique de Pettitt (1979) et de corrélation de Spearman. L’évolution annuelle de la pluviométrie moyenne sur la période 1971-2020, a montré une tendance à la hausse dans la zone d’étude. Les années déficitaires représentent 52% dans la commune de Djougou et 48% dans la commune de Tanguiéta. Au cours de la période d’étude, la température de la zone d’étude a connu une hausse de 0,39 °C. L’application des tests de stationnarité aux données pluviométriques a permis de déterminer des années de ruptures à Djougou en 1992 et à Tanguiéta à 1989 au seuil de significativité de 95% synonyme de changements des conditions pluviométriques. Les corrélations établies entre les rendements et les séries pluviométriques ont montré qu’il n’existe pas de relations explicites entre ces deux variables. Vegetable production is potentially affected by the effects of climate variability in West Africa. This is why, this study proposed to analyze the impact of climate variability on tomatoes and pepper yields in the municipalities of Djougou and Tanguiéta. It has based on an analysis of rainfall and temperature trends from 1971 to 2020 of the region and the statistical tests of Pettitt (1979) and Spearman correlation. The annual evolution of average rainfall over the period 1971-2020 shows an upward trend in the study area. Deficit years represent 52% for Djougou municipality and 48% for Tanguiéta municipality. During the study period, the temperature of the study area increased by 0.39 °C. The application of stationarity tests to rainfall data indicated the break in series in 1992 for Djougou municipality and 1989 for Tanguiéta municipality at the 95% significance threshold synonymous with changes in rainfall conditions. The correlations established between yields and rainfall have shown that there is no explicit relationship between these two variables.
