Climate Change, Livelihoods and Violent Conflict in Central Mali Maiga, Mahamadou The potential effect of climate change on violent conflict has remained one of the livelier debates across the world for several decades. Surprisingly, despite the large number of studies devoted to that, results remain so far inconclusive and even contradictory sometimes. Although there is no consensus yet, this may not be sufficient to conclude the absence of relationships. Instead, in this dissertation we suggest that the impacts of climate change on violent conflict are conditional on the sensitivity of livelihoods to climate change and the resulting conflict-sensitive coping practices developed at the individual level. Hence, our main objective is to explores how do climate change-induced deterioration of livelihoods and the resulting adaptation practices affect the likelihood of conflict in Central Mali. This is a region highly susceptible to climatic extreme shocks and mired in armed conflict for so long time. Specifically, we aim to: (i) evaluate the perceptions of local communities on climate change and its economic impacts on livelihoods in Central Mali; (ii) estimate the influence of livelihoods as affected by climate change on people’s support for violence; (iii) assess the effect of increase in farm size as exacerbated by climate change and related livelihoods loss on people intergroup relations. Primary data was collected on households for tackling these objectives. The data have been analyzed using different econometrical approaches. Hence, a Multinomial Probit and binary logit models were employed for the specific objective one. The second and third objectives were addressed using the Recursive Bivariate regression model. In summary, the results show that local communities in Central Mali do perceive the changes occurring in weather and their negative effects on livelihoods. As a consequence, people develop coping practices (which are very often conflict-sensitive) likely to disrupt their intergroup relations and further increasing the willingness of supporting the use of violence in times of crises. In line with these results, we believe that policies providing local communities affected by climate change with alternative livelihoods strategies would improve their resilience capacity. Moreover, engaging local communities in collectively-designed adaptation strategies could help to better manage the societal implications of environmental change on conflict. In addition, it is also essential to clearly define land ownership rights, as well as the boundaries of cropping and grazing areas and pastoral routes, in order to break the connection between climate change and conflict.

Urban green spaces and their contribution to the resilience of the big cities in West Africa: Case of Niamey, Niger Moussa, Yahaya Maazou In recent decades, cities in West Africa are becoming large due to the high population growth rate. This urbanization is accompanied by the transformation of the environmental and social conditions affecting the dwellers‟ livelihoods and well-being, thereby making them more vulnerable to climate change. Thus, this study attempts to investigate the contribution of urban green spaces to climate resilience in Niamey City as the case of the big West African cities. Specifically, it aims to: i) Analyze urban green spaces accessibility: the current state in Niamey city; ii) Analyze the determinants of the urban green spaces management practices in Niamey city; and iii) Assess the contribution of the urban green spaces to the climate resilience in Niamey city. For that, the qualitative and quantitative methods were applied to the primary and secondary data. The qualitative relies on semi-structured interviews, focus group discussions, and personal observations, while the quantitative relies on the primary data from the survey (390 respondents), geospatial data, and secondary data. For the first specific objective, the green index per capita, proximity to green spaces indicator, and qualitative indicators such as safety, comfort, attractiveness, and maintenance were used. For the second objective, the multinomial logistic model was used; and the partial proportional odds model for the last objective. The results showed that despite the urban green spaces are not currently in good condition with the accessibility of 6.04 m2 per capita, they contribute significantly to the respondents‟ climate resilience. Thus, the respondents close to the green spaces are more likely to be climate resilient. In addition, the respondents who perceive the regulating and cultural services are more likely to be climate resilient than those who perceive the provisioning services. This performance is attributed to the urban green space management practiced by the respondents, which is influenced significantly by shade as the benefits they get from urban green spaces. In light of the results, this study suggests promoting projects that aim to develop urban green areas across the city to make them more accessible to dwellers, thereby increasing their climate resilience.

Adoption of Stress Tolerant Maize for Africa Varieties and Resilience to Climate Change among Maize Farmers in Derived Savannah Zone, Nigeria Francis, Phillips Chimezie The decline in maize yield in Nigeria is largely attributed to droughts and floods. Farmers' ability to anticipate, prepare for, adapt to, and recover from the impacts of climate changes and extreme weather is crucial to mitigate the attendant economic losses This study examined the effect of adoption of the new Stress Tolerant Maize Varieties of Africa (STMA) on the resilience of smallholders maize farmers to climate change in the Derived Savanah zone of Nigeria. A multistage stratified random sampling procedure was used to select 520 maize farming households from 13 villages and data was elicited using a well-structured questionnaire. Descriptive statistics, Heckman Selection Model, Resilience Index Measurement and Analysis II (RIMA-II) and Endogenous Switching Regression Model (ESRM) were employed to analyse the data. Results reveal that majority of the maize farmers are in their productive age, cultivating an average of 3.94 ha of farmland, most of whom perceived the incidence of all the climate change indicators considered in the study. Results of the Heckman two-staged selection model show that the age of household head, farming experience, income sources, and location are significant variables influencing household food security of the maize farmers, while schooling years, household size, and market distance are significant in influencing the productivity of maize farmers in the study area. The first stage of the ESRM reveals that farmers’ awareness of both improved maize varieties and the STMA varieties, gender, and household size are positive and statistically significant in determining the adoption of STMA varieties. The second stage reveals that farming experience, income sources, and awareness of improved maize varieties are negative and statistically significant in explaining the variation in resilience to climate change among the farmers that adopted the STMA varieties, while schooling years, dependency ratio, off-farm income, income sources, market distance, extension access and awareness of improved maize variety are negative and statistically significant in explaining the variation in resilience to climate change among the non-adopters. Adoption of STMA varieties has a significant positive impact on resilience to climate change. Thus, awareness of STMA varieties and easy access to certified STMA seeds should be included in any agricultural development programmes and extension communication in Nigeria.

Climate Risk Management in Senegal: Climate Change Impact, Farmers' Vulnerability, and Risk Financing Mechanisms through Insurance for Rice Farmers Ndimblane, Mouhamadou Lamine Climatic risks, droughts and floods are increasing and appear to be a major threat to the agricultural economies of the Sahelian countries, particularly those of West Africa, given their heavy dependence on rainfed agriculture. To this end, climate change is likely to exacerbate the vulnerability of a large number of farmers already characterized by low means of substances and limited possibilities of choice to adapt to climate risks. Government funding resources being limited, the prioritization of national adaptation policies is therefore an important aspect of effectively meeting the needs of farming communities. This research work examines the impact of climate change on the rice sector in Senegal, the vulnerability of rice farmers and the means of financing climate risks. Autoregressive Distributed Lag Model (ARDL), index Method and Endogenous Switching Regression Model (ESRM) are used to assess the impact of climate change on rice sector GDP, rice farmers' vulnerability and impact of insurance on household income respectively. Using time series data for the period 1961-2020, the estimated results show that in the short term, an increase in precipitation and temperature of 1% increases GDP per capita by 0.54% and by 3. 52% respectively, ceteris paribus. The vulnerability assessment results carried out using an integrated approach combining climatic, socio-economic, socio-demographic and environmental variables show that out of 33 municipalities studied, two (2) are at a very high level of vulnerability of order 0.61 to 0.70, six (6) are in a state of high vulnerability of 0.53 and 0.60 and another six (6) are in a moderate situation (0.46 to 0.52), this which gives an idea of the order of priority of adaptation policies in the different localities considered. Moreover, the results revealed that agricultural insurance is a good financial instrument to deal with climate risks. The policy implications that emerge from this research suggest that communication about insurance and building the capacity of farm households through agricultural extension and advisory services facilitates understanding and encourages farm households to use insurance to climate risk management. The strengthening of human capital through education and training, the development of institutional capital through the development of basic social infrastructure, transport and credit institutions, as well as economic capital through the promotion of agricultural insurance and irrigation development, constitute fundamental policy measures to reduce vulnerability and improve resilience of the farming communities studied.
