The results of the analysis show that 26.7% of the respondents were women. 73.3% were men. In this regard (p = 0.705), no significant differences were observed between communities. Cocoa farming is increasingly a male rather than a female activity. This is an indication that the traditional role of women in the cultivation of food crops for family consumption is changing. In their study of farmers' perceptions and practices of natural resource management in the face of climate change in Ntui, Chimi et al. (2022) observed this trend. Given the profitability of cocoa farming, women may be seeking to initiate and implement projects. Moreover, these results are consistent with those of [38], [39], [40], [41], [42], who found a strong male dominance in agricultural production. The average age of the farmers ranged from 32.7 to 47 years. The statistical test indicates that there is no significant difference in the average age between the villages (F = 0.47, p = 0.711). This means that the respondents are middle-aged. They are still fit enough to participate in agricultural production activities. In terms of household size, the mean values ranged from 2.9 to 6.9. The statistical test confirms that there is no significant difference in household size between villages (F = 1.28, p = 0.291). In terms of farming experience, the mean values for the number of years of farming experience ranged from 10 years to 20.6 years. The statistical test suggests that there is no significant difference in the length of farming experience between villages (F = 0.61, p = 0.611). The average size of the useful agricultural area varies from 2.4 to 4.5 hectares. The statistical test showed no significant difference in the values of the useful agricultural area between the different villages (F = 0.76, p = 0.521). This means that farmers in Mbangassina have been involved in agricultural production activities for a long time and operate on a small scale in the locality. Therefore, their extensive experience will help them to better understand climate change. Finally, the average annual income ranges from FCFA 2,834,000.0 to FCFA 9,089,533.3. The statistical test confirms that there is no significant difference in annual income between villages (F = 0.22, p = 0.881).
Mbangassina is located in the heart of Cameroon's Centre Region. It is much more than a geographical point. It is a microcosm of resilience. Here, farmers, families, and individuals are confronting the effects of climate change. Small-scale farmers, often unrecognized, work the land. They tend to the crops that sustain their families and communities. Their daily lives are affected by climate variability. From erratic rainfall to rising temperatures. Agriculture is the main activity that is widely practiced in the localities of Mbangassina, an essential characteristic of the rural areas of Cameroon, as highlighted by the National Institute of Statistics (NIS) in its report entitled "Annuaire Statistique du Cameroun, édition 2015". In terms of respondents' knowledge, 97.2% of the farmers in the survey indicated that they had been aware of changes in temperature and rainfall over the past 30 years. However, the dependent variable "perception of climate change" is significantly positively correlated with age (β = 0.021; p = 0.043) and annual income (β = 0.079; p = 0.046). In contrast, the number of years of farming experience (β = -0.044; p = 0.045) has a significantly negative correlation. These results are in line with those of [43], who found similar results in his work on perceptions, local knowledge, and adaptation strategies developed by producers in two communities in northern Benin. The majority of smallholder farmers in the Mbangassina ecological zone of transition from forest to savannah feel that the climate has changed in the last 10 to 30 years. Respondents reported late arrival of rains, rains in the middle of the dry season, irregular rains, and intense and prolonged droughts as climate changes. These findings suggest that the smallholder farmers are familiar with the climate of their region and are aware of the climate change that is underway. Numerous studies worldwide and in Africa have reached similar conclusions [18], [44], [45], [46], [47], [48]. Similarly, farmers in the Dodoma region of Tanzania were found to be generally well-informed about climate change by [49], and [50]. However, about whether or not climate change was occurring, some smallholder farmers remained undecided. Several factors could explain this diversity in perceptions among smallholder farmers in the Mbangassina subdivision.
Mbangassina's seasons are characterized by short and long dry seasons, followed by short and long rainy seasons. However, these patterns are not as predictable as before. From generation to generation, the elders of Mbangassina have passed on their wisdom. They recognize subtle signs as indicators of weather changes, such as the call of a particular bird or the behavior of ants. The most noticeable climatic parameters have been temperature, rainfall, drought, and the beginning and end of the dry season over the past 10 to 30 years. Compared to other parameters such as relative humidity or barometric pressure, these observations are more obvious to respondents. These findings are similar to those of researchers in Benin [51], [52], Ntui in Cameroon [18], and Togo [53]. The only difference is that the beginning and end of the dry season were not recorded in their studies. It is important to note that despite global efforts to replenish the ozone layer, climate change continues to evolve. This is especially true in different localities. In agriculture, smallholder family farmers face an imprecise distribution of seasons. Previously, these seasons were well-defined. This uncertainty has a direct impact on their agricultural activities and creates anxiety among these farmers. Traditional varieties that are resistant to local conditions are struggling to thrive, despite their efforts to diversify their crops (plantains, cassava, peanuts) to protect themselves from climatic risks. As a result, crop yields are declining. Certain pests and diseases are on the rise, and new ones are emerging. Numerous studies around the world have found similar results. Faced with these challenges, farmers are often struggling. This may explain the low annual incomes of the farmers surveyed. In the hope that the rains will arrive on time, farmers adjust their planting schedules. Average temperatures fluctuate between 23°C and 25°C. Heat waves are a challenge for both people and crops. Management of water sources is essential, and shade trees are becoming a refuge. Finally, smallholder farmers are concerned about soil degradation due to erosion, deforestation, and intensive agriculture. Fortunately, in response to these challenges, innovative practices such as agroforestry and organic farming are gaining ground.
Significant changes in mean and maximum temperatures were observed in the analysis of climate trends. Thus, for precipitation, maximum, and mean temperatures, the hypothesis H1, indicating the existence of a trend, was accepted. On the other hand, hypothesis H0, which indicates the absence of a trend, was maintained for the minimum temperature. However, although the Mann-Kendell test confirmed H0 for minimum temperature, Sen's slope generally shows an increasing trend in temperatures (minimum, maximum, and mean) over the last 40 years in the Mbangassina transition zone. A warming climate over time is indicated by these positive slopes. R2 values are a measure of how well the linear regression lines fit the observed data. Higher R2 values are an indication of a better fit. However, it is important to note that linear regression is a simplified model. Other factors such as greenhouse gases, natural variability, and regional effects also contribute to temperature changes.
Between 1981 and 2022, Mbangassina recorded an average annual rainfall of 1,491.26 mm. The yearly rainfall fluctuates during this period. The R2 value (0.237) suggests that this linear model does not fit the data perfectly. The downward trend implies a decrease in annual rainfall over time. Some climate trends are influenced by complex factors such as climate variability, land use change, and regional influences. Precipitation patterns, for example, are the result of multiple interactions. These include seasonal variations, geographic factors, and climatic oscillations. It is through meteorological data that farmers perceive these climatic changes. Indeed, records show minimum and maximum temperatures increasing. Similarly, farmers' perceptions of rainfall trends are consistent with precipitation observations. However, these findings differ from some studies conducted in Tanzania. [54], [55], [56], [57], and [58] found that farmers in the semi-arid central region of Tanzania perceived climate change in terms of anomalies in total annual rainfall. These changes included increasing temperatures, extending the dry season, and changing rainfall intensity. Farmers were well informed about climate change in the Dodoma region of Tanzania. To adapt to these changes, they favored practices such as crop rotation, reduction of cultivated area, ridging, and crop rotation.
The objective of this study was to further analyze the factors that influence the perception of climate change by smallholder farmers in the sub-division of Mbangassina. By examining the goodness of fit coefficients of binary logistic regression, several indicators of model quality were identified. These indicators are about the respondents' adoption of adaptation measures. The results showed that the coefficient for the variable age was negative (-0.160). This indicates a negative relationship with the dependent variable. However, the associated p-value (0.110) is greater than 0.05. This means that this relationship is not statistically significant. For household size, the coefficient is positive (0.066). This indicates a positive relationship. The corresponding p-value (0.104) is also greater than 0.05. This means that this relationship is not statistically significant. Finally, farming experience has a negative coefficient (-0.076). This indicates a negative relationship. The corresponding p-value (0.045) is less than 0.05. This means that this relationship is statistically significant. These results could be an indication that the stakeholders may be vulnerable to future climate change despite the measures in place. However, the need for these indicators for better monitoring of changes in an environment should be in mind. Furthermore, the results of the analysis show that the agricultural area has a negative correlation with a coefficient of -0.123. This correlation is statistically significant as the p-value (0.038) is below the threshold of significance. This correlation is statistically significant. The corresponding p-value (0.038) is below the 0.05 threshold. In other words, decreasing agricultural land is associated with decreasing annual income. On the other hand, the coefficient for annual income is positive (0.202). This indicates a positive relationship. The corresponding p-value (0.037) is also less than 0.05, confirming the statistical significance of this relationship. This suggests that stakeholders may be vulnerable to future climate change despite the measures taken. In conclusion, these indicators can reveal vulnerabilities. However, their use remains essential for monitoring changes in the environment.
The vast majority of respondents felt that the transition zone between forest and savannah in Mbangassina illustrates the community's awareness of the role of agriculture in adapting to climate change. Community-based climate change awareness programs could be based on this area. Research [59] has shown that individuals adapt to the impacts of climate change based on their observations. The decision to implement adaptation measures was most likely motivated by observed changes in climate change indicators. In Africa, studies show that the majority of farmers are aware of changes in temperature and rainfall and are already implementing adaptation measures such as diversifying crops, migrating, selling livestock, and conserving soil [18], [60], [61], [62]. This growing literature on adaptation in Africa is shedding light on how and where adaptation is taking place, while also highlighting the risks of maladaptation associated with inappropriate responses [63], [64]. In addition, farmers perceive a decrease in rainfall, an increase in temperature, and other factors [27]. Adoption of water and soil conservation techniques, ownership of manure pits, irrigation, and varietal adaptation are among the main adaptation strategies. Therefore, to preserve agricultural biodiversity in the context of climate change, adaptation measures in the Mbangassina transition zone should be based on local knowledge.
We examined the associations and contrasts between certain socioeconomic and perceptual variables using binary logistic regression. The results indicate that the variables microfinance/bank client (Pr > Wald = 0,046; Pr > LR = 0,036), gender (Pr > Wald = 0,049; Pr > LR = 0,015), community member (Pr > Wald = 0,059; Pr > LR = 0,023) and residential status (Pr > Wald = 0,079; Pr > LR = 0,001) are statistically significant at different confidence levels. Their values Pr > Wald and/or Pr > LR are less than 0.05. This means that these variables have a significant effect on the dependent variable in the logistic regression model. The estimation of the model coefficients for the variable of perception of climate change shows that microfinance/bank client (β = -0.471; p = 0.046) and gender (β = -0.627; p = 0.049) have negative coefficients. This suggests: As these variables increase, the probability of a "yes" response decreases, according to the binary logistic regression results. On the other hand, the parameters of being a member of the community (β = 0.637; p = 0.049) and living situation (β = 3.137; p = 0.043) have positive coefficients. This indicates that as these variables increase, the likelihood of answering "yes" increases. The fact that the respondent selection criteria for some of these variables did not allow for dissenting responses could explain these results. In addition, climate change is undeniable and ubiquitous. Therefore, it is likely that all social classes are aware of it. These results are different from those obtained by [18], who found that variables such as level of education and age group have an impact on perceptions. However, they also found that the status of the residence (temporary, permanent, or seasonal) plays a role in these perceptions. Therefore, it is important to seek the opinions of people who are permanent residents when it comes to perceptions of climate change in a given environment. Similarly, [65] found that a high proportion of farmers in the Kyuso district of Kenya were aware of the impacts of climate change, which was influenced by age, gender, education, farming experience, and access to extension services, among other factors.
