“…For each agro-ecological zone, data from one point (weather station) were used to represent the entire agro-ecological zone. Our temperature data came from the global gridded dataset (Climate Research Unit (CRU) Time-Series Atmosphere 2020, 11,190 4 of 18 (TS) v4.03) provided by the Climate Research Unit (CRU) at the University of East Anglia, United Kingdom [24]. Given the low spatial and temporal coverage of meteorological stations in Africa, the CRU dataset provides alternative data for climate analysis and has been used in previous studies focused on Nigeria, Africa, and global climate models [25][26][27][28].…”

An in-depth understanding of the impact of vulnerability on livelihoods and food security is important in deploying effective adaptation actions. The Nigerian agricultural sector is dominated by rainfed and non-homogenous smallholder farming systems. A number of climate change risk studies have emerged in the last decade. However, little attention has been given to vulnerability assessments and the operationalization of vulnerability. To highlight this shortcoming, this study systematically reviewed climate-change-focused vulnerability assessments in the agricultural sector by evaluating (1) variation in climate variables in Nigeria over time;(2) the state of climate change vulnerability assessment in Nigerian agriculture; (3) the theoretical foundations, operationalization approaches, and frameworks of vulnerability assessments in Nigeria; (4) the methods currently used in vulnerability assessments; and (5) lessons learned from the vulnerability studies. We used a linear trend of climatic data spanning over a period of 56 years obtained from the Nigerian Meteorological Agency and the Climate Research Unit of the University of East Anglia, United Kingdom, along with a systematic review of literature to achieve the objectives. The analysis indicates a significant and positive correlation between temperature and time in all major agro-ecological zones. For precipitation, we found a non-significant correlation between precipitation in the Sahel, Sudan, and Guinea Savanna zones with time, while the other zones recorded positive but significant associations between precipitation and time. The systematic review findings indicate no clear progress in publications focused specifically on vulnerability assessments in the Nigerian agricultural sector. There has been progress recently in applying frameworks and methods. However, there are important issues that require addressing in vulnerability assessments, including low consideration for indigenous knowledge and experience, unclear operationalization of vulnerability, non-standardization of vulnerability measures, and inadequacy of current assessments supporting decision making.

“…Hahn et al (2009), observed that the field of climate vulnerability assessment has emerged to address the need to quantify how such communities will adapt to changing environmental conditions. Research on vulnerability assessment of systems to climate variability and change has emerged in studies and in scientific reports contributing to scientific knowledge in the area (Jakpa 2015, Dumenu and Obeng 2016, Nyamwanza et al 2017. CCA falls under the IPCC definition of vulnerability, which is the degree to which a system is susceptible to, or unable to cope with, adverse effects of climate (IPCC 2007).…”

The impacts of changing climate on agriculture have consequences on livelihoods and food security. Smallholder farmers, who have heterogeneous farming systems and limited resources, compounded with multiple risks, are greatly affected. There has been limited research showing how vulnerability assessments have evolved in the smallholder agricultural sector of Africa overtime. This study systematically reviewed recent publications on vulnerability studies, especially among smallholder agricultural systems, to provide an overview of current developments in theory and practice of vulnerability in Africa over the last decade. The findings indicate an increase in vulnerability assessments undertaken across Sub Saharan Africa. Despite progress made in the application of enhanced conceptual frameworks and methods, at least four important gaps exist in the assessment process namely, inadequate engagement of local perspectives and knowledge, lack of clarity in the operationalisation of vulnerability, lack of comprehensiveness of measurement criteria employed and relevance of assessment in decision support. Notwithstanding these challenges, there exist opportunities to geographically improve assessments across Africa. In order to produce knowledge to traverse projected changes in climate systems for agricultural economies and to ensure sustainable smallholder livelihoods, we suggest that future research efforts should be oriented towards providing more information to enlighten science, policy and practice for informed decision-making and evidenced based policies. This requires evaluation of adaptation capacity as a critical aspect of vulnerability assessment to provide guidance and inform effective decision-making on allocation of scarce resources (prioritization); understand trade-offs management and implementation to build understanding among stakeholders that guide possible pathways to reduce vulnerability.

Develop medium‐ to long‐term climate information services to enhance comprehensive climate risk management in Africa

Increasing climate change risks in Africa, emerging from global warming and their interaction with non‐climate risks such as market, have increased the need for comprehensive Climate Risk Management (CRM) that considers both climatic and non‐climatic risks and enables actions that address the underlying drivers of vulnerability to these risks. However, comprehensive CRM requires holistic Climate Information Services (CIS), that is, CIS that balances between components focused on provision of short‐ and long‐term climate information for both local and non‐local decision makers. In this article, we ask: to what extent is CIS in Africa holistic? We review recent and ongoing CIS interventions in Africa to determine whether a balance of components between short‐ and long‐term CIS for local and non‐local decision makers is achieved for holistic CIS. We find a focus on provision of short‐term, that is, Sub‐Seasonal‐to‐Seasonal (S2S) CIS for local and non‐local decision makers, with limited focus on medium‐ to long‐term (MLT) CIS, particularly MLT CIS for local decision makers which represents the biggest gap to achieving holistic CIS in Africa. We present a supported case that ensuring holistic CIS in Africa will require a portfolio‐based approach to CIS development, particularly focusing on MLT CIS for local decision makers. We further highlight the need for integration of this MLT CIS for local decision makers into existing CIS. Achieving this will require: (a) experimentation and innovation with different CIS formats, products and timeframes to enable learning and flexibility to achieve desired goals; (b) capacity development of producers and consumers of climate information to ensure that they have the skills and expertise to understand and generate, and articulate needs and consume MLT CIS respectively; and (c) coordinated allocation of financial resources to ensure that all components of the holistic CIS are advanced.
