The mainstream climate change community has primarily concerned itself with mitigation and adaptation strategies, both of which require monitoring and prediction. These four inter-connected response actions (mitigation, adaptation, monitoring and prediction) constitute the main strategies for managing climate change. This paper aims to weigh in on policies and societal coordination for effective management of the earth’s climate with respect to these four elements in Africa because of its socioeconomic peculiarities.

The Delphi experts’ method backed by questionnaires was used to obtain relevant data for the study. The questionnaires were distributed to professionals dealing with issues related to climate change response and sustainability in various parts of the world, with a focus on Africa.

With respect to the strategies that are most needed for effective climate change actions in Africa, government’s policies, activities and decisions rank highest at 1.20 with a p-value of < 0.001, and financing is next at 0.93, mitigation is 0.83, prediction is 0.76 and adaptation is 0.68 (p = 0.048), at the 5 per cent cutoff. Also, for the most appropriate approaches to managing climate change across Africa, regional efforts are at least 8 times more effective than country-wide approaches, followed by continental efforts at 6.51 times, international cooperation at 3.99 times and inaction at 0.00 times.

The paper concludes that a holistic climate change management approach is important in Africa to contain the impacts of climate change in the continent.

This paper aims to provide an analysis of gender strategies in the planning, programmes towards the implementation of Africa’s Nationally Determined Contributions (NDCs). It involved the identification and disaggregation of climate risks on women key climate affected sectors (water, energy, agriculture, health, energy).

This involves review of vast scholarly and academic research, to establishment of linkages and interlinkages between the risks. A diagnostic analysis was done on the NDCs to understand the orientation of gender considerations in the NDCs of African countries, and then an assessment on emerging opportunities and empowerment of women to address climate change was carried out as an un-detachable component of gender considerations.

Poverty, cultural barriers and inequality, climatic risks such as floods, occurrence of infectious diseases and water scarcity create life threatening situations for women as well as their livelihood Analysis on the NDCs (and INDCs) of all African countries show that over 85% of actions reference gender. At the regional level West Africa has the highest gender actions in their NDCs (41%), East Africa 25%, Southern Africa 15%, Central Africa 8% and North Africa 6%. The coping responses of women, their knowledge about the environment and the environmental services they offer, provide great opportunities for them in the climate change scenario which is seldom spoken about. Empowerment of women by providing access to Information, education, training; sensitization on various facets of climate change; the risks, consequences, possible sustainable solutions (Adaptation and mitigation) and their basic rights especially with regards to land and ownership is necessary, and can help reduce the climatic risks they face.

The limitation of this study was time constraint as the research was done during my fellowship at the United Nations Economic Commission for Africa which was a short period in relation to the fact that the authors were assigned to other duties.

Though most African countries are making an effort towards gender integration in their NDCs, they need to carry out systematic gender analysis; collecting and using sex-disaggregated data; establishing gender-sensitive benchmarks and indicators; and developing practical tools to support increased attention to gender perspectives.

Climate change is a serious threat to humanity and views from mostly those affected indicates that there is still a big disconnect between the ambitious agendas set by various stakeholders involved (International organizations, governments and regional organizations), and the real grassroots initiatives, actions and programs being implemented in the ground. There is also inarguably increasing evidence that climate change is amplifying gender inequality, the vulnerability of women and children; consequently, a serious barrier to the achievement of the Paris Agreement, UN 2030 Sustainable development goals, the 2063 Africa Union Agenda.

Though there exist many research papers on climate and gender and also on NDCs, creating a link between gender risks and climate policies, strategies and programs gives the issue of gender and climate change “high importance”. An integrated approach on identifying the risks makes policies coherent.

The purpose of this paper is to review and document some of the climate change impacts which may burden the African continent, and to suggest policy options for adaptation.

The paper presents a comprehensive review of published papers on climate change impacts and adaptation.

It has been documented that by 2050, the world will have to limit emissions of all greenhouse gases to the equivalent of 400 GT of carbon in order to stand a 75 per cent chance of avoiding more than 2°C of warming. This is practically impossible because there are not enough resources and technology to achieve that target. Even if all of the emissions are stopped in next few years, it will take the next 40 years for the world to follow its current trend before full recovery. Thus, climate will continue to change, its impacts will continue to increase and Africa is placed as the most vulnerable continent. The only best solution is that the vulnerable population should be first in line for support to adapt to climate change impacts. In such instances adaptation policy should recognise and support a wide range of options for building resilient and sustainable livelihoods, enhancing opportunities available for adaptation, without ignoring the need to address the existing developmental challenges.

This paper relies on secondary source of information.

The paper is a valuable input towards the preparation of adaptation policy in developing countries.

This paper relied on review of secondary data (published articles) thus providing critical findings from a number of field studies.

The purpose of this paper is to synthesise lessons from research on adaptation to demonstrate that African countries can explore the opportunities and challenges inherent in climate variability and change.

The paper is a review work which synthesises lessons from relevant journal articles and other related documents. The literature was retrieved from Google and Google Scholar using search terms such as climate change, climate change and mitigation, climate change and mitigation in Africa, climate change adaptation and mitigation in Africa, climate change vulnerability, climate change impacts, among others. Various combinations of the search terms were also deployed. The journals were subjected to critical review and key lessons synthesised from them and reflections on their future implications in relation to climate risks and vulnerability presented.

Key lessons were synthesised and reflections on their future implications in relation to climate risks and vulnerability were presented. The evidence seems to suggest that countries in Africa recognise that it is time for them to take action on the impacts of climate change. The key lessons which emerge, going forward, are that climate change adaptation should be mainstreamed into development plans of nations. All efforts should be geared towards sustaining livelihoods of people. Key stakeholders also have a role to play in adaptation. The paper has indicated that although a lot has happened, there are areas that require strengthening and that should be the focus and priority of change and policy makers for the future.

The paper is a synthesis and reflection of existing literature and it is possible that some of the dynamics may have changed since the paper was published.

The dynamics of climate change adaptation is understood. The approaches to adaptation are also explored. Areas worth prioritising in the discourse of adaptation studies have also been indicated.

The syntheses provided are the reflections of the author. The views of the researcher provide insights and understanding into the current adaptation debate.

The purpose of this study is to examine the biophysical and socioeconomic impacts of climate change on maize production and food security in sub-Saharan Africa (SSA) using adapted improved maize varieties and well-calibrated and validated bioeconomic models.

Using the past climate (1950-2000) as a baseline, the study estimated the biophysical impacts of climate change in 2050 (2040-2069) and 2080 (2070-2099) under the A1B emission scenario and three nitrogen levels, and the socioeconomic impacts in 2050.

Climate change will affect maize yields across SSA in 2050 and 2080, and the extent of the impact at a given period will vary considerably between input levels, regions and maize mega environments (MMEs). Greater relative yield reductions may occur under medium and high-input intensification than under low intensification, in Western and Southern Africa than in Eastern and Central Africa and in lowland and dry mid-altitude than in highland and wet mid-altitude MMEs. Climate change may worsen food insecurity in SSA in 2050 through its negative impact on maize consumption and reduction in daily calorie intake. However, international trade has the potential to offset some of the negative impacts.

The study calibrated and applied bioeconomic models to estimate the biophysical and socioeconomic impact of climate change on maize production at fine resolution. The results could be used as a baseline to evaluate measures that will be applied to adapt maize to the future climate in SSA.

It is globally accepted that climate change is presently the greatest threat to the sustainability of human livelihood and biodiversity. Most farmers in the study area are highly aware of climate change and its consequences on the farming system; however, mitigation strategies are clearly lacking. Among the mitigation, mechanism to reduce the threat is achieved by increasing the amount of carbon sinks and reducing greenhouse gas emission through the adoption of agroforestry practices. The purpose of this study is to determine if awareness on climate change leads to the adoption of agroforestry practices, and to examine the determinants.

A total number of 117 questionnaires were administered to the farmers in the district using stratified random sampling technique. Data were captured and analysed using STATA and XLSTAT software. Descriptive statistics and Heckprobit sample selection model were used to determine the objectives of the study.

The result established that climate change awareness does not lead to the adoption of agroforestry in the study area in which information source and member’s association were statistically significant at (p < 0.1) and (p < 0.05), respectively, and determine the adoption of agroforestry practices, while farming experience (p < 0.1), age (p < 0.05), extension visit (p < 0.05) and education (p < 0.1), were the determining factors that influence the awareness of climate change in the study area.

Regular number of extensions visit, information and training on agroforestry should be provided to the farmers in the study area.

Farmers’ association should be strengthened among the rural farmers.

The causal effect or relationship of climate change awareness on mitigation through the practice of agroforestry in South Africa, especially in the study area, has not been measured. This research set a pace in the area of climate change awareness leading to mitigation strategies through the use of agroforestry practices as an option to be used in the rural farming area of South Africa.

Three Coupled Model Intercomparison Project Phase 5 models involved in the G4 experiment of the Geoengineering Model Inter-comparison Project (GeoMIP) project were used to investigate the impact of stratospheric aerosol injection (SAI) on the mean surface air temperature and precipitation extremes in Africa.

This impact was examined under G4 and Representative Concentration Pathway (RCP) 4.5 scenarios on the total precipitation, the number of rainy days (RR1) and of days with heavy rainfall (R20 mm), the rainfall intensity (SDII), the maximum length of consecutive wet (CWD) and dry (CDD) days and on the maximum rainfall in five consecutive days (Rx5day) across four regions: Western Africa (WAF), Eastern Africa (EAF), Northern Africa and Southern Africa (SAF).

During the 50 years (2020–2069) of SAI, mean continental warming is −0.40°C lower in G4 than under RCP4.5. During the post-injection period (2070–2090), the temperature continues to increase, but at a lower rate (−0.19°C) than in RCP4.5. During SAI, annual rainfall in G4 is significantly greater than in RCP4.5 over the high latitudes (especially over SAF) and lower over the tropics. The termination of SAI leads to a significant increase of rainfall over Sahel and EAF and a decrease over SAF and Guinea Coast (WAF).

Compared to RCP4.5, SAI will contribute to reducing significantly regional warming but with a significant decrease of rainfall in the tropics where rainfed agriculture account for a large part of the economies. After the SAI period, the risk of drought over the extratropical regions (especially in SAF) will be mitigated, while the risk of floods will be exacerbated in the Central Sahel.

To meet the Paris Agreement, African countries will implement mitigation measures to contribute to keep the surface air temperature below 2°C. Geoengineering with SAI is suggested as an option to meet this challenge, but its implication on the African climate system needs a deep investigation in the aim to understand the impacts on temperature and precipitation extremes. To the best of the authors’ knowledge, this study is the first to investigate the potential impact of SAI using the G4 experiment of GeoMIP on temperature and precipitation extremes of the African continent.

This paper aims to investigate and review adaptation measures in the livestock sector from 21 African countries through literature survey and grounded theory approaches. The adaptation themes that emerged captured essence of measures and experience drawn from varied country submissions and contexts instituted to make the livestock sector climate compatible in as far as adaptation is concerned.

Literature survey approach was used on the impacts of climate change on livestock and a review of the submitted adaptation measures. The study used grounded theory approach to derive meaning from the retrieved information. The grounded theory was derived inductively through systematic collection and analysis of data pertaining to the submitted National Communications reports. The retrieved themes were then examined and interpreted to give meaning and draw conclusions through coding, conceptualizing, categorizing and theorizing.

Results identify eight adaptation themes: carrying capacity and policies; integrated pasture management; capacity building, extension, training, awareness and information sharing; livestock breeding, diversification and intensification; disease, vectors and parasites management; technology, innovation, research and development; alternative livelihood; and water supply. The findings show that African Governments have been implementing effective adaptation measures for food security through building a climate resilient livestock production system.

This study is one of the first to lead to recommendations that decision- and policymakers, private sectors, relevant stakeholders and government officials and scientists should play a key role in ensuring that adaptation measures reach farmers, herders at grassroots level. In addition, governments should create an enabling environment (policies) in climate change adaptation to improve food security. These recommendations might be helpful in many communities where adaptation to climate change is a pressing issue.

This paper aims to understand the impacts of climate changes on groundwater resources in the African continent in which groundwater components constitute one of the most indispensable resources for development.

Observed data are used for the first time to illustrate the manifested impacts of climate changes on the groundwater resources either directly or indirectly, this includes the comparison between isoheytal maps as well as water level data versus time.

The results of the analysis suggest that climate change is likely to impact groundwater resources, either directly, e.g. via changing precipitation patterns, or indirectly, e.g. through the interaction of changing precipitation patterns via changing land‐use practices and water demand. These changes may concern both groundwater quantity and quality. Climate change will affect groundwater recharge rates, i.e. the renewable groundwater resource, and groundwater levels. Any decrease in groundwater recharge will exacerbate the effect of sea‐level rise. In inland aquifers, a decrease in groundwater recharge can lead to saltwater intrusion of neighbouring saline aquifers, and increased evapotranspiration in semi‐arid and arid regions may lead to the salinisation of shallow aquifers.

In Africa, climate change and variability have the potential to impose additional pressures on water availability, water accessibility and water demands which will directly be impacted on eradicating poverty as a direct consequence of climate changes on sustainable development in Africa. A more refined understanding from specialists should be addressed to raise public and stakeholder awareness in this respect.
