In the wake of deepened situations of changing climate, a clear understanding of the perceived impacts and adaptation of climate variability and change on livelihoods of vegetable farmers in Western and Eastern Africa, which is not readily available, is critical for sustainable vegetable production in Africa. Development planning for climate change vulnerability and adaptation assessment was utilised in the study. Using multi-stage sampling procedure, 193 vegetable farmers in selected sites prominent for vegetable production from Uganda, Ghana and Nigeria were used. Data were analysed using descriptive statistics, analysis of variance and linear regression at α0.05. Awareness of climate variability and change was high among most respondents from the three countries, but highest among respondents from Uganda (78.3%). Awareness was highest for long dry spell ($$\bar{x}$$ x ¯  = 1.90) and drought ($$\bar{x}$$ x ¯  = 1.81) and lowest for harmful gas emissions ($$\bar{x}$$ x ¯  = 0.76). Changes in climate variability and trends were perceived to be highest in terms of flood volume/damage caused by flood to farmlands in Nigeria ($$\bar{x}$$ x ¯  = 3.85) and Uganda ($$\bar{x}$$ x ¯  = 5.0), but in terms of increased temperature for Ghana ($$\bar{x}$$ x ¯  = 4.93). Impact of climate-related changes on vegetable farming was high in Ghana (98.3%) and Nigeria (46.6%) but low in Uganda (5.0%). Awareness (β = 0.14), perception (β = 0.15) use of adaptation strategies (β = 0.10) and household size (β = − 0.19) predicted change in perceived impact of climate variability among vegetable farmers. Vegetable farmers in Nigeria, Ghana and Uganda are affected differently by climate variability. Farmers in these countries also have different priorities for adaptation strategies. Locality-specific climate adaptation strategies would help ease farmers burden due to climate change.

The changing climate has negatively impacted food systems by affecting rainfall patterns and leading to drought, flooding, and higher temperatures which reduce food production. This study examined the ability of communities to cope with food insecurity due to the changing climate in the Serere and Buyende districts, which are two different agro-ecological zones of Uganda. We administered 806 questionnaires to households, a sample size which was determined using Yamane’s formula, with the snowball sampling method used to select the households. The questionnaire sought information, including that regarding the respondents’ resources, the effects of climate change on households, and the coping mechanisms employed to reduce the impact of climate change on food security. The data collected was coded and analyzed using the statistical package for the social sciences (SPSS). Agriculture was found to be the main source of income for 42.4% of male adults and 41.2% of female adults in Serere. In Buyende, 39.9% of males and 33.7% of females rely on selling animal, poultry, and food crops. Aggregate results further showed that 58.3% of females and 42.2% of the males from both districts had suffered from the impacts of climate change, and that the effects were more evident between March and May, when communities experienced crop failure. The study further found that the percentage of households who had three meals a day was reduced from 59.7% to 43.6%, while the number of households with no major meals a day increased from 1.3% to 1.6%. We also found that 34.3% of households reported buying food during periods of crop failure or food scarcity. Moreover, despite reporting an understanding of several coping mechanisms, many households were limited in their ability to implement the coping mechanisms by their low incomes. This reinforced their reliance on affordable mechanisms, such as growing drought-resistant crops (32.7%), rearing drought-resistant livestock breeds (26.1%), and reducing the number of meals a day (14.5%), which are mechanisms that are insufficient for solving all the climate-related food insecurity challenges. We recommend that the government intervenes by revising policies which help farmers cope with the negative effects of climate change, promoting the sensitization of farmers to employing the coping mechanisms, and subsidizing agricultural inputs, such as resistant varieties of crops, for all to afford.

An assessment of the socio-economic implications of landslide occurrence in the Kigezi highlands of South Western Uganda was conducted. Landslide occurrence is on the increase and threatens community livelihoods in these highlands. Detailed field investigations were undertaken with the help of local communities between June 2018 and May 2020 to identify and map recent and visible landslide scars in Rukiga uplands of Kigezi highlands. In the course of field inventories, 85 visible landslide scars were identified and mapped using handheld GPS receivers to produce a landslide distribution map for the study area. A socio-economic analysis was conducted to establish the effects of landslide damage on people’s livelihoods as well as their existing coping and adaptation mechanisms. The assessment was administered through field observations and surveying, focus group discussions, key informants and household interviews as well as the use of Local Government Environmental Reports. The study established an increase in the spatial-temporal distribution of landslides over the Kigezi highlands in the past 40 years. The landslides have resulted in a reduction in the quality of land, loss of lives, destruction of transport infrastructures, settlements, farmlands, crops and other socio-economic infrastructures. Therefore, it is important to look for reliable and sustainable measures to prevent landslide hazards. Total landscape reforestation with deep-rooted trees can possibly reduce the landslide risk. It is also important to undertake policy implementation for preparedness and mitigation plans against landslides in this region and in the country at large. Proper soil and water conservation measures could help in enhancing soil strength against landslide hazards.

Weather and climate issues have become increasingly recognized among the global challenges especially in the era of climate change. Kampala city has faced a number of flooding events in the past that have led to serious damages in many low lying areas of the city. A study was conducted in one of the flood prone areas in Kampala city to understand the community perspectives on flood occurrence and weather forecasting in the area. The main objective was to understand community perceptions on flood occurrence as well as use of weather information for early warning. Data was collected from 400 respondents using a structured questionnaire as well as focused group discussions. Results from the survey revealed that 99.8% of the respondents reported rainfall intensities to have increased in the last 5 years and as a result, 96% of these respondents stated floods as the main climate risk in the area. The most common impacts of floods in the community included loss of property, lack of safe and clean water and disease outbreaks among others. In response to floods, the community identified use of raised tables or stands and use of stones in the compound as the main coping mechanisms employed in the community. In terms of weather alerts, only 22% of respondents reported receiving the weather alerts issued by the Uganda National Meteorological Authority (UNMA). Of those who receive the alerts, 91% hear the information mainly on television. Therefore, the study proposes strengthening of collaboration between UNMA and the local leaders through the Kampala Capital City Authority (KCCA) for provision of earlier weather forecasts that help reduce the negative flood impacts among communities.

Climate change affects both men and women which, in turn, shapes their varied and contrasting perceptions of climate variability and change. This paper examined the gendered perceptions of climate variability and change among local communities in Queen Elizabeth National Park in Uganda.The objectives are threefold: - identify climatic shocks faced by the local communities; examine the perceptions of men and women of climate variability and change; and to compare their perceptions with empirical meteorological data. This study employed both qualitative and quantitative methods, with data collected from 215 respondents using survey, interviews and focused group discussions. From the findings, indicators of climate variability and change included reduced flooding events, occurrence of human diseases, increasing crop pests and diseases, dry spells and intensity of rains. There was increasing significant temperatures while rainfall was declining. Both male and female significantly associated with increasing temperatures and reduced flooding events. While climatic shocks affected both males and females, the impact was more pronounced depending on distinct livelihood activities and roles and responsibilities undertaken. The study concluded that people’s perceptions of climate change should be taken on by the government and integrated in the national climate programs that support people’s livelihoods and survival mechanisms.
