Climate-Smart Agriculture, Climate Risk Vulnerability, and Food Security in Côte d’Ivoire: Exploring the Role of Gender Soro, Tiemongo Esther This dissertation examines the interrelations between Climate-Smart Agriculture (CSA), climate vulnerability, and food security, with a particular focus on gender inequalities in Côte d’Ivoire. Employing econometric techniques and survey data, it analyses farmers’ perceptions of climate change, the determinants of CSA practice adoption, and the gender-differentiated effects on food security and vulnerability. Despite growing awareness of climate variability, CSA adoption remains low, with fewer than 20% of households in the Hambol region implementing the majority of the 35 identified practices. Agroforestry emerges as both a widely adopted and effective practice, contributing to food security while supporting climate adaptation and mitigation. However, a lack of awareness regarding CSA benefits remains a major barrier to its uptake. The gender analysis highlights notable disparities: improved seeds increase food security by 33.9% in female-headed households, whereas intercropping improves it by 47.3% in male-headed ones. Overall, CSA practices enhance food security by 41.3%, with respective gains of 29.7% for women and 45.7% for men. Through an endogenous change model, the research demonstrates that adopters experience a 4.84% reduction in vulnerability, compared to a 21% increase among non-adopters. Improved seeds and intercropping reduce vulnerability by 5.76% and 4.5%, respectively, while non-adoption results in increases of 7.54% and 24.74%. Socio-economic factors such as age, household size, and access to healthcare also reduce vulnerability, whereas climate shocks, including droughts and floods, exacerbate it. The combined adoption of CSA practices enhances resilience by diversifying income sources and strengthening adaptive capacities. Policy implications include strengthening meteorological services, providing targeted training, facilitating gender-sensitive credit access, and implementing land reforms to ensure equitable adoption.

Climate Change, Migration and Food in(Security) in West Africa Coastal Zones: A Case Study of Senegal Sow, Khodia This thesis aims to analyse the link between climate change, migration and food security in Senegal, particularly among fishing households. It focuses first on analysing the impact of climate change on the food security of Senegalese fishing households, then on analysing migration as a climate adaptation strategy to improve food security, and finally, it studies the interconnection between climate change, migration and food (in)security. This thesis used primary data collected from 570 Senegalese fishing households, as well as secondary data. The estimation techniques used were generalised least squares (GLS), Heckman and vector autoregression (SVAR). The results suggest that climate change has a negative impact on Senegalese fishing households by reducing their average daily income. The results also show that migration is a strategy used by Senegalese fishermen to adapt to climate change. Furthermore, there is a bidirectional relationship between migration, food security and climate change. It is recommended to promote seasonal migration, control catches, avoid overfishing and promote climate change adaptation strategies by creating other activities. Thus, the Senegalese government should orient its policy in this direction in order to revive the fishing sector and reduce illegal migration of fishermen.

Climate Change and Conflict in Sahel Sawadogo, Soumaïla This dissertation assesses the effect of climate change on conflict in the Sahel. The first chapter reviews the major types and drivers of community conflict in Burkina Faso, from 2015-2022, highlighting land use disputes and farmer-herder tensions. The study finds that climate change act as a threat multiplier of community conflict in Burkina Faso in particular land-use disputes and farmer-herder conflict. In addition, some socio-economic factors affect the occurrence of community conflicts. This result implies that policies should address the social, political and institutional weakness that allow environmental stress to escalate into conflict. The second chapter investigates the effect of climate change vulnerability on farmer-herder conflicts. For this purpose, we constructed household-level vulnerability index to climate change from our survey data. By employing mixed methods using quantitative analysis and qualitative data description, we find that quantitively vulnerability to climate change positively influences farmer-herder conflict. This finding is confirmed with qualitative data description since both farmer and herder reveal that the degree of their vulnerability explains the emergence of conflicts. Then, when elaborating policies that can reduce farmer-herder conflict regarding their vulnerability, effort should be focused on increasing farmer-herder resilience via-a-visa of climate change effect and mitigate climate change effect, promote tolerance for social diversity, and support stakeholders (who intervene in conflict management).The third chapter investigates empirically the role of migration as a mediator in the vulnerability to climate change and internal conflict nexus. By employing structural equation modelling, the study finds that vulnerability to climate change affects directly conflict and that 73.5% of the total effect operates through migration channel. This means that migration plays a partial role in the transmission of conflict in the Sahel. Since vulnerability to climate change affect directly conflict in Sahelians countries, police response should focus on reducing climate vulnerability through adaptation measures. Together, the dissertation contributes to the literature on climate security by offering empirical evidence from a vulnerable region and provides policy recommendations to address emerging climate security risks.

Climate risk and climate services perception, and the efficacy of adaptation and mitigation strategies in agriculture, The Gambia Ceesay, Sheriff Climate variability and extreme weather events present growing challenges to agricultural systems globally, particularly for smallholder farmers in The Gambia who depend on rain-fed farming. Rising temperatures and erratic weather patterns have worsened food insecurity, reduced harvests, and strained local adaptation efforts. This research aims to examine farmers' perceptions of climate risks, assess the factors influencing their access to and use of climate information, and evaluate the effectiveness of adaptation and mitigation strategies. The study was structured around three empirical essays based on data collected from 420 farm households across three agricultural regions in The Gambia in 2023. A combination of econometric and qualitative techniques including binary logistic regression, multinomial and multivariate probit models, and a perception index—was applied to analyse the data. Key findings reveal that age (35–55), access to markets, extension services, training on climate risks, and trust in media significantly enhance the use of climate information, which in turn is positively associated with adopting adaptation strategies. Results further show that land tenure, government support, and past weather shocks influence on-farm adaptation, while off-farm strategies are more common among middle-aged and female farmers. Gender disparities were evident, with women less likely to adopt formal adaptation measures. A perception index of 0.66 indicates a moderate level of confidence in the effectiveness of current adaptation and mitigation strategies, with farmers showing a strong preference for crop diversification and irrigation methods. The research underscores the importance of integrating farmers’ perceptions and local realities into national climate policies. Strengthening extension services, improving access to credit, and providing gender-sensitive support are critical for building resilient farming systems and advancing sustainable agricultural development in The Gambia.
