The research methodology employed in this study aimed to comprehensively investigate the agricultural practices in Palau, with a focus on understanding the challenges and opportunities within the sector.The research design incorporated a mixed-methods approach, combining quantitative and qualitative data collection and analysis to achieve a holistic understanding of the complex agricultural landscape.
The study targeted a representative sample of farmers in Palau, employing a stratified random sampling technique.Stratification was based on geographical regions within the country to ensure a diverse representation of agricultural practices.The sample size, determined through power analysis, comprised 200 farmers, providing sufficient statistical power for the study.
A structured questionnaire was developed as the primary instrument for data collection.The questionnaire was designed to capture key variables related to agricultural practices, climate resilience, soil management, and socio-economic factors.To ensure content validity, the questionnaire underwent a thorough review by experts in agriculture, environmental science, and survey methodology.
Content validity was further strengthened through a pilot test conducted with 30 farmers not included in the main sample.Feedback from the pilot study facilitated refinement of question wording and clarity.Additionally, the questionnaire underwent a reliability analysis, achieving a Cronbach's alpha coefficient of 0.85, indicating high internal consistency.
Fieldwork was conducted over a three-month period, during which trained enumerators administered the structured questionnaire through face-to-face interviews with the selected farmers.The survey covered aspects such as crop choices, farming techniques, pest management, and adaptation strategies to climate change.
Quantitative data obtained from the questionnaire were analyzed using a variety of statistical methods.Descriptive statistics, including means and standard deviations, were computed to characterize the central tendencies and variabilities of key variables.To explore relationships, Pearson correlation coefficients were calculated for variables such as climate resilience, soil health, and crop yields.
For inferential analysis, t-tests were employed to compare means between different groups, such as traditional and modern farming practices.Analysis of Variance (ANOVA) was used to assess variations in crop yields across different geographical regions.Regression analysis was conducted to identify predictors of climate resilience and crop yields, with socio-economic and environmental variables considered as potential predictors.
Furthermore, to control for potential confounding factors, Analysis of Covariance (ANCOVA) was utilized.This allowed for a more nuanced examination of the relationships between independent variables and dependent outcomes while accounting for the influence of covariates.This comprehensive analytical approach aimed to uncover patterns and associations within the data, providing valuable insights into the factors influencing agricultural practices in Palau.The t-test results comparing traditional and modern farming practices reveal significant differences in crop yields (t = -2.45,p = 0.018).Traditional farming practices yielded an average of 23.10, while modern farming practices had a significantly higher average of 28.50.However, there were no statistically significant differences in climate resilience (t = 1.80, p = 0.076), soil health (t = -1.20,p = 0.232), and farm size (t = 1.60, p = 0.112) between the two farming approaches.These results suggest that while modern practices may lead to higher crop yields, there is no substantial evidence of differences in other measured variables.The correlation matrix provides insights into the relationships between key variables.A positive correlation exists between crop yields and climate resilience (r = 0.45, p < 0.01) and between crop yields and soil health (r = 0.32, p < 0.05), indicating that as one variable increases, the other tends to increase.However, there is a weak negative correlation between crop yields and farm size (r = -0.21,p < 0.05), suggesting that larger farms may experience slightly lower crop yields.Climate resilience shows a positive correlation with soil health (r = 0.28, p < 0.05), emphasizing the interconnected nature of environmental variables in agricultural contexts.The multiple regression analysis aims to identify predictors of crop yields.The intercept (15.20) represents the estimated crop yield when all predictor variables are zero.Climate resilience (β = 3.80, p = 0.002) and soil health (β = 2.50, p = 0.006) significantly and positively contribute to crop yields.A unit increase in climate resilience is associated with an increase of 3.80 in crop yields, and a unit increase in soil health is associated with an increase of 2.50 in crop yields.Conversely, farm size (β = -1.10,p = 0.031) has a negative impact on crop yields, indicating that larger farms tend to have slightly lower crop yields.The overall model was statistically significant (F = 9.62, p < 0.001), suggesting that the combination of these variables explains a significant portion of the variance in crop yields.The ANCOVA test explores the impact of climate resilience on crop yields, controlling for farm size.The intercept (18.50) represents the estimated crop yield when both climate resilience and farm size are zero.Climate resilience (β = 4.20, p < 0.001) remains a significant positive predictor of crop yields, even after accounting for farm size.A unit increase in climate resilience is associated with an increase of 4.20 in crop yields, holding farm size constant.Farm size (β = -0.90,p = 0.028) retains its negative impact on crop yields, indicating that larger farms tend to have slightly lower crop yields, independent of climate resilience.The overall model is statistically significant (F = 11.92,p < 0.001), suggesting that the combination of climate resilience and farm size explains a significant portion of the variance in crop yields.
