The variability, intensity, and distribution of rainfall have drawn a lot interest globally especially in nations where rainfed agriculture is the norm. This article uses data from Rwanda Meteorology Agency for years 1981 to 2021 delineate analyze variability trends Kayonza District. time series were grouped using K-means clustering technique based on computed Euclidean distance, total within-cluster sum squares, elbow plot determine optimal number clusters. coefficient variation measures was employed while Sen’s slope Mann–Kendall (MK) test used, respectively, find changes magnitude. results indicated four near homogeneous zones named region one four. dry seasons higher compared rainy annual with 128–142% over southeastern part during June August (JJA) season, 16–48% observed most district both seasons. It further noted that areas central District significant increasing trend at significance level 95% above January February (JF), September December (SOND), basis, March May (MAM) JJA season exhibited no trend. findings this study are essential creating adequate mitigation strategies lessen climate change’s effects as well other socioeconomic sectors.

Abstract This study examines gender vulnerabilities and responsive strategies to climate change, comparing evidences from Kwara Nassarawa States in Nigeria. Changes parameters, gender-based perceptions of climate, as well response adaptation practices were assessed accordance with specific research objectives. A total 200 participants surveyed through a mixed method approach using 41 years data. Semi-structured questionnaires administered equally the two 52 in-depth interviews conducted within male female farmers that 40 above age purposive sampling method. Results State showed downward trend rainfall an upward both minimum maximum temperatures. The perceived change differently, observed changes variables: temperature precipitation, resulting extreme floods, drought, onset leading varying practices. concluded plays significant role adoption agricultural sector males often have more access resources decision-making power farming heads households. There is need for better gender-sensitive approaches planning implementation ensure men women equal opportunities benefit options agriculture.

Cross-cultural validity DSO is still being debated cultural norms significantly influence how individuals perceive themselves manage their emotions relationships. The aim this systematic review understand were experienced expressed by from Sub-Saharan Africa (SSA) exploring qualitative literature. Searches conducted on nine databases using search terms for countries, methods, symptoms, trauma exposure. Fifty studies included. Results confirmed presence three clusters. However, manifestation differed defined diagnostic criteria, highlighting importance considering factors process. Additionally, indicated that structural played significant roles shaping interpretation trauma-related distress context. Thus, we propose create implement module an add actual assessment tools account variations SSA population improve accuracy. In perspective, more emic research needed gain deeper understanding perceived, experienced, interpreted SSA.

Research and policy analyses of climate change adaptation in Africa are often centre to examine adjustments agricultural operations. This mainly bases on a misconception that rural households merely depend agriculture for their livelihoods. research aimed at positioning livelihood (farm non-farm activities) as the strategies better understand households' strategic options capacities, using two communities Northern highlands Ethiopia. The result showed have broader both farm combating adverse condition than previously reported. A strong positive association found between wealth indicators such size (0.08) productive assets (0.0917) with farm-level short maturing crop irrigation. Non-farm (such business activities wage employment) are, mainly, influenced by household demographic characteristics age head (0.01) adult (0.09). indicates there is no specific strategy panacea households. Rather, use mix meet particular agro-ecological settings (for strategies), infrastructure location community, which enable access market other services strategies). Thus, national level policies need be tailored address agro-ecology, local area socio-economic context communities. In this regard, different levels government non-governmental organizations should provide more measures extension services, loans, roads, transport, market, knowledge creation employment opportunities vicinity its surrounding towns.
