Many projections of the impact of climate change on the crop, livestock and fishery production sectors of African agriculture are reported in the literature. However, they may be arguably too general to understand the magnitude of impact and to inform adaptation strategies and policy development efforts that are tailored to promoting climate-smart agriculture in the West African region alone. This paper was synthesized from several scholarly literature and aimed at providing up-to-date information on climate change impacts, adaptation strategies, policies and institutional mechanisms that each agriculture subsector had put in place in dealing with climate change and its related issues in West Africa. For each subsector (crop, fishery and livestock), the current status, climate change impacts, mitigation and adaption strategies have been analyzed. In addition, we reviewed recent policy initiatives in the region that foster the development and adoption of climate-smart agricultural options to improve resilience of farming systems and livelihoods of smallholder farmers to climate change risks. From community to national and regional levels, various strategies and policies are also being taken to guide actions and investment for climate-smart agriculture in West Africa.

The gender perspective of climate information use is not well studied although necessary for developing gender-responsive climate information services (CIS). This study determined how CIS use by men and women farmers may be influenced by their perceptions about climate change (CC), farm activities, and demography. The study was carried out at the Lawra-Jirapa Districts of the Upper West Region of Ghana where downscaled seasonal forecast information through mobile phone technologies (Esoko platform) had been disseminated to farmers since 2011. Data was collected from semi-structured questionnaire interviews involving 900 farmers (50.2% women and 49.8% men) and four 20-member focus group discussions. The study confirmed 85.2% (representing 767) farmers were aware of climate change and its implications for their agriculture and other livelihood activities. Men and women had similar perceptions about climate change, perceived by the majority as increased strong winds, higher temperatures, increased frequency of drought, increased rainfall variability and increased flooding. Among other factors, it was evident that use of CIS may be influenced by gender. Men were found to be particularly responsive in adopting CIS use for climate risk mitigation. This was attributed to their ability to easily access and use telephone devices compared with women. The study revealed that unlike women, men were able to access more financial resources and had control of household income which allowed them to purchase mobile phones. Women generally accessed their husbands’ mobile phones. Despite differences in access to CIS, the study showed both men and women found it beneficial for strategic farm decision-making such as when to begin land preparation, when to plant, and which crop to select. In addition, both men and women were found to face similar constrains (such as poor network connectivity and limited of training), to accessing and using CIS through the Esoko platform. The study recommends the need to explore different CIS dissemination channels and design CIS that meet gender-specific needs.

In the literature, a lot of information is available about climate change perceptions and impacts in sub-Saharan Africa. However, there is limited attention in the region to emerging initiatives, technologies and policies that are tailored to building the adaptive capacity of agricultural systems to climate change and variability. In this paper, we discuss the prospects for climate-smart agriculture technologies and enabling policies in dealing with climate change and variability at different sub-regional levels of sub-Saharan Africa to sustain farm productivity and livelihoods of agrarian communities. The review provides substantial information suggesting that without appropriate interventions, climate change and variability will affect agricultural yields, food security and add to the presently unaceptable levels of poverty in sub-Saharan Africa. Although some of them were already existing, the past decades have seen the development and promotion of climate-smart agriculture innovations such as the use of high yielding drought tolerant crop varieties, climate information services, agricultural insurance, agroforestry, water harvesting techniques, integrated soil fertility management practices, etc. In the context of climate change, this appears as a stepping up approach to sustainably improving farm productivity, rural livelihoods and adaptive capacity of farmers and production systems while contributing to mitigation. The development of regional, sub-regional and national climate change policies and plans targeted at mitigating climate change and improving adaptive capacity of the African people have also been developed to enable mainstreaming of climate-smart agriculture into agricultural development plans. Financial commitments from governments and development agencies will be crucial for improving large scale adoption of climate-smart agriculture.

In the context of climate change, climate variability has become a major issue in recent years in sub-Saharan countries. Climate information services (CIS) could be a vital resort for African producers to better manage climatic risks. This study aimed to identify CIS needs and analyze the most adapted dissemination channels while also determining factors that influence smallholder access. This was done with a gender lens where 1170 farmers (20% women) were surveyed from 11 regions in Senegal. Two probit regressions were performed. Results revealed that men and women have different needs for CIS, with 95% of women requesting information relating to the onset date of rainy season against 90% for men (p < 5%). Similarly, 46% of women prefer rural radios as a CIS broadcast channel compared to 39% of men (p < 5%). Also, the main factors influencing the access are ethnicity, area of residence, and farmers’ perceptions of the utility of CIS. Among women, the native status and the willingness to act against climate change affect the access to CIS. Thus, to facilitate access to CIS for relevant decision-making, it remains important to capacitate farmers and to consider the producers' organizations as platforms for CIS dissemination and trainings.

Climate information is recognized as a powerful tool to reduce the effect of climate risk and uncertainty on crop production and increase the resilience and the adaptive capacity of farmers in semi-arid zones. This paper estimates farmers’ willingness to pay (WTP) for climate information within cowpea and sesame value chains in Northern Burkina Faso. The study used the contingent valuation method for a monetary valuation of farmers’ preferences for climate information. Data were collected using a structured questionnaire from 170 farmers. The study found that 63% of respondents were willing to pay for climate information services (CIS) such as seasonal climate forecast (SCF), decadal climate information (10-DCI), daily climate information (1-DCI) and agro-advisories. The predicted value for the WTP was XOF 3496 for SCF, XOF 1066 for 10-DCI, XOF 1985 for 1-DCI and XOF 1628 for agro-advisories. The study also showed that several socioeconomic and motivation factors have greater influence on farmers’ WTP for CIS. These included the gender, age, education of the farm head and the awareness of farm head to climate information. The outcomes of this paper should support policy makers to better design an efficient mechanism for the dissemination of climate information to improve the adaptive capacity of farmers to climate risks in Burkina Faso.
