In an agrarian economy like Ghana, the need to understand climate change is as paramount as finding solutions to address the challenges of climate change. While a large body of literature has focused on exploring the impact of climate change, very few studies in Ghana have attempted to expand our knowledge on the extent of climate change across ecological zones in Ghana. This study used Ghana Meteorological Agency's climate data from 1989 to 2015, to assess the characteristics and trends of rainfall and temperature across the six ecological zones in Ghana. With the aid of descriptive statistics, Mann-Kendall test, linear regression, analysis of variance and post-hoc comparison using Tukey HSD test, the study found increasing trend of temperature and decreasing rainfall across ecological zones and provided policy recommendations essential to offset the adverse impact of climate change particularly on agriculture.

This study adopted mixed methods design and employed questionnaire and interview to investigate climate trends and smallholder farmers' perception of climate change as well as the relationship between climate data and farmers' perception, and the determinants of perception in Adansi North District of Ghana. The study randomly and purposively selected 378 respondents and 41 key informants, respectively. Descriptive, inferential, trend and thematic analysis were employed. Results showed that the majority of smallholder farmers have observed increase in intensity (96.8%) and duration (94.7%) of temperature, and delay onset (82.8%) and early cessation (89.2%) of rainfall as well as increase in wind intensity (79.4%). Climate data also revealed rising trends of rainfall, wind speed and temperature. Nevertheless, there was no significant relationship between farmers' perception and climate data. Information from family and friends and government, particularly local institutions and extension service significantly influence farmers' perception. In addition, television and radio were significant predictors of farmers' perception. The study recommends intensification of climate education, mass awareness and capacity development programmes.

This study investigates smallholder farmers’ perceived impact of climate variability on subsistence agriculture. The study further explores household food security from access perspective and the factors that influence food accessibility in the rural Adansi North District of Ghana. The study randomly selected 378 smallholder farm households while 41 key informants were purposively selected. Questionnaire survey and semi-structured interview were employed to collect primary data. Descriptive and inferential analysis were computed for quantitative data while qualitative data was analyzed thematically. Results show that climate variability greatly affects subsistence agriculture, as a result of the reduction in agriculture yields, thereby leading to household food insecurity. It also emerged that the majority of households (58%) experienced food anxiety while 62% were unable to access their preferred quantity and quality food. Household food security is significantly influenced by gender, household size, years of farming experience, access to forest and adaptation. The implications of the study have been teased out alongside the recommendations.

This study examined smallholder farmers' adaptation strategies in managing fall armyworm (Spodoptera frugiperda) in rural Ghana. Using mixed methods, 378 smallholder farmers were randomly selected and surveyed, while 41 key informants were interviewed. The majority of smallholder farmers (83.1%) had experienced fall armyworm invasion with widespread and rapid invasion particularly in maize, which often led to a considerable reduction in crop yields. Pesticides (88%) and washing detergent solution (44%) applications were the common pest management practices. Male farmers were more positive in applying pesticides than female farmers. Integrated pest management practices and education among farmer should be improved.
