Sustainable Urban Drainage Practices and Their Effects on Aquifer Recharge
Authors: Gichuhi Getrude , Gitahi Stephen 
Published: May 2021

AbstractBetween 1994 and 2006, an 18% increase of freshwater flow into the earth’s ocean was recorded, as well as extreme weather events such as prolonged drought and intense floods. Following this period was an era of increased evaporation from oceans and seas, which heightened global warming in Africa. This chapter proposes the use of man-made aquifers recharge processes as methods of draining water into the soil before the runoff water reaches water bodies. Source control involves controlling the volume of water entering drainage systems or rivers by cutting off runoff water through storing for reuse or evapotranspiration as seen in green roofs. Pre-treatment is the use of trenches to filter and remove contaminants from water before getting to water bodies. Retention systems on the other hand is controlling the rate at which water is discharged to waterways by providing water storage areas such as ponds, water retention areas, etc., while Infiltration Systems are areas that allow natural soaking of stormwater runoff to the ground naturally recharging the water table. The proposed methods will see replenishing of the water table, a great leap in the efforts of curbing global warming. This practice can easily be adopted by both individuals and government as we build more and more buildings creating a balance between the need for human settlement and the natural way of water replenishing itself. The methods do not introduce extra costs to an already existing budget. In some cases, the methods help to reduce the costs of projects especially in urban areas. Africa which hosts many of the growing countries sees and will continue to experience surges in urbanization. For such, these methods presented in this topic will be, if implemented, a best method to solve the urban drainage problems before this even occurs.
Smart Climate Resilient and Efficient Integrated Waste to Clean Energy System in a Developing Country: Industry 4.0
Authors: Matheri Anthony Njuguna , Mohamed Belaid , Ngila Jane Catherine 
Published: May 2021

AbstractClimate change impacts a natural and human system on the entire globe. Climate-related extreme weather such as drought, floods, and heat waves alters the ecosystems that society depends on. Climate, land, energy, and water systems (CLEWS) are a critical aspect of high importance on resource availability, distribution, and interconnection. The nexus provides a set of guidelines to South Africa that aims on creating a level playing field for all sectors while achieving the aims of the SDGs that are cross-sectoral and multilevel approaches to climate change. The nexus expressed three domains that included resources, governance, and security. It integrated a smart climate resilient with inclusion of the governance and involvement of the stakeholders. Recognition of spatial and sector interdependencies should inform policies, investment and institutional for enhancing nexus security and climate change towards making transition green carbon deals. The nexus offers an integrated approach that analyzes the trade-offs and synergies between the different sectors in order to maximize the efficiency of using the resources that adapt institutional and optimum policy arrangements. Economic transformation and creation of employment through green economy is one of the COP26 green deal agendas in curbing the carbon emissions (green house emission, industrial processes, fuel combustion, and fugitive emissions) as mitigation to climate change, which is cost-effective and economically efficient. The future climate change policy in the developing countries is likely to be both promoted by climate technology transfer and public-private cooperation (cross-sector partnership) through the technology mechanism of the nexus and inclusion of the gender.
Climate-Induced Food Crisis in Africa: Integrating Policy and Adaptation
Authors: Chiawo David O. , Otiende Verrah A. 
Published: May 2021

AbstractClimate change threatens development and economic growth in Africa. It increases risks for individuals and governments with unprecedented negative impacts on agriculture. Specifically, climate change presents a major threat to food security in Africa for the long term due to the low adaptive capacity to deal with successive climate shocks. There is a need for greater awareness of the trends of food crisis patterns and adaptive initiatives. The objective of this chapter was to analyze the trends of the food crisis in Africa within the past 10 years and adaptive initiatives. Quantitative data analyzed for food security indicators were obtained from the United Nations Food and Agriculture Organization (FAO) and World Development Indicators (WDI) available at the Environment and Climate Change data portal. Policy and adaptation measures related to climate change were reviewed in 26 countries in Africa, with the view to highlight their integrative nature in enhancing food security. High prevalence of undernourishment was observed in six countries, all in sub-Saharan Africa (SSA) including Chad, Liberia, Central African Republic, The Democratic Republic of the Congo, Zambia, and Zimbabwe. Countries with a high land acreage under cereal production recorded reduced undernourishment. Niger demonstrated effective adaptation for food security by registering the highest crop production index in extreme climate variability. However, Kenya appears to be the most predisposed by registering both high climate variability and below average crop production index. It is observed that diversification and technology adoption are key strategies applied across the countries for adaptation. However, the uptake of technology by smallholder farmers is still low across many countries in SSA.
Triple Helix as a Strategic Tool to Fast-Track Climate Change Adaptation in Rural Kenya: Case Study of Marsabit County

Published: May 2021

AbstractThe lack of affordable, clean, and reliable energy in Africa’s rural areas forces people to resort to poor quality energy source, which is detrimental to the people’s health and prevents the economic development of communities. Moreover, access to safe water and food security are concerns closely linked to health issues and children malnourishment. Recent climate change due to global warming has worsened the already critical situation.Electricity is well known to be an enabler of development as it allows the use of modern devices thus enabling the development of not only income-generating activities but also water pumping and food processing and conservation that can promote socioeconomic growth. However, all of this is difficult to achieve due to the lack of investors, local skills, awareness by the community, and often also government regulations.All the above mentioned barriers to the uptake of electricity in rural Kenya could be solved by the coordinated effort of government, private sector, and academia, also referred to as Triple Helix, in which each entity may partially take the other’s role. This chapter discretizes the above and shows how a specific county (Marsabit) has benefited from this triple intervention. Existing government policies and actions and programs led by nongovernmental organizations (NGOs) and international agencies are reviewed, highlighting the current interconnection and gaps in promoting integrated actions toward climate change adaptation and energy access.
Panel Analysis of the Relationship Between Weather Variability and Sectoral Output in Kenya
Authors: Mulama Olga Nekesa , Kariuki Caroline Wanjiru 
Published: May 2021

AbstractClimate change and economic growth are closely connected. Climate change has the potential to reduce economic growth in developing countries due to their limited ability to respond to the negative impacts of a changing climate. A better understanding of weather variability can enhance climate change policies, which would help to support economic growth in these countries. As such, this research sought to examine if there is a long-run relationship between sectoral output and weather variables (temperature and rainfall) and to analyze the effect of weather variability on sectoral output using a panel of 13 sectors in Kenya.A Pedroni cointegration test was carried out to find out if there exists a long-run relationship among the variables and thereafter, a fully modified ordinary least squares regression was conducted to establish the effect of weather variability on sectoral output. The results indicate that there is a long-run relationship between temperature and sectoral output. Moreover, temperature has a larger effect on sectoral output compared to rainfall. With the evidence gathered from this research, it can be concluded that weather variability has an economic effect on sectoral output in Kenya. Given this, the Kenyan government needs to take a keen interest in understanding the effect of weather variability on the economy and in the broader picture, take steps to mitigate climate change.
Climate Change Adaptation in Southern Africa: Universalistic Science or Indigenous Knowledge or Hybrid
Authors: Mutambisi Tafadzwa , Chanza Nelson , Matamanda Abraham R. , Ncube Roseline , Chirisa Innocent 
Published: May 2021

AbstractThe aims of this chapter are to seek answer, through a document review, case studies, and thematic content analysis, to which direction Southern Africa should take in the face of climate change and to suggest a framework for adaptations by communities experiencing climatic events. Acknowledging that the fundamental set of ideas provided by indigenous knowledge (IK) works best at a small scale, the chapter argues for the need to seriously value IK-based response practices in the knowledge hybridization agenda. The worsening vulnerability potentiated by the increasing magnitude and severity of climate change impacts is a reminder that local-based indigenous response practices in Africa need to be complemented. Adaptation to climate change calls for real and surreal measures all being applied in combination. Across Africa, these measures have, at times, included the preservation of forest resources which increased carbon sinking and enhanced community resilience against climate change. Universalistic and orthodox sciences have punctuated and amplified these efforts by speaking of such initiatives as mitigation and adaptation through programs, e.g., Reducing Emissions from Deforestation and Forest Degradation (REDD+) and ecosystem-based adaptation (EbA). The merits of the two approaches have resulted in increasing call among scholars for the merging of these programs with IK. However, it remains to be fully understood how such a hybrid approach could be operationalized without treating the latter as an inferior element in climate science discourses.
Climate Change Adaptation Mechanism for Sustainable Development Goal 1 in Nigeria: Legal Imperative
Authors: Orie Erimma Gloria 
Published: May 2021

AbstractDespite international efforts on poverty reduction in the last decade, poverty is rampant in many countries including Nigeria. Poverty remains a principal challenge for development in twenty-first century and a threat to achievement of Sustainable Development Goal (SDG) 1, which is a global attempt, among others, to end poverty by 2030. Meanwhile, 13 out of the 15 countries where extreme poverty is rising are in Africa. According to the World Poverty Clock, Nigeria, by 2018, had the largest extreme poverty population of 86.9 million, thus making the people vulnerable to malnutrition, armed conflict, migration, and other socioeconomic and environmental shocks. Whereas these impacts are exacerbated by climate change (CC), unfortunately, Nigeria’s adaptation efforts are inadequate due to certain impediments. The chapter finds that Nigeria lacks the CC law to properly regulate institutional and policy interventions to impacts of CC. It argues that although adaptation as opposed to mitigation is interim, yet integrating adaptation measures into Sustainable Development (SD) framework and poverty reduction strategies is a potent means of addressing CC impacts on the poor and achieve SDG1 target. The chapter therefore recommends the establishment of CC law in Nigeria that incorporates adaptation measures in poverty reduction strategies and mainstreaming of CC issues.

AbstractBiomass Burning (BB) aerosol has attracted considerable attention due to its detrimental effects on climate through its radiative properties. In Africa, fire patterns are anticorrelated with the southward-northward movement of the intertropical convergence zone (ITCZ). Each year between June and September, BB occurs in the southern hemisphere of Africa, and aerosols are carried westward by the African Easterly Jet (AEJ) and advected at an altitude of between 2 and 4 km. Observations made during a field campaign of Dynamics-Aerosol-Chemistry-Cloud Interactions in West Africa (DACCIWA) (Knippertz et al., Bull Am Meteorol Soc 96:1451–1460, 2015) during the West African Monsoon (WAM) of June–July 2016 have revealed large quantities of BB aerosols in the Planetary Boundary Layer (PBL) over southern West Africa (SWA).This chapter examines the effects of the long-range transport of BB aerosols on the climate over SWA by means of a modeling study, and proposes several adaptation and mitigation strategies for policy makers regarding this phenomenon. A high-resolution regional climate model, known as the Consortium for Small-scale Modelling – Aerosols and Reactive Traces (COSMO-ART) gases, was used to conduct two set of experiments, with and without BB emissions, to quantify their impacts on the SWA atmosphere. Results revealed a reduction in surface shortwave (SW) radiation of up to about 6.5 W m−2 and an 11% increase of Cloud Droplets Number Concentration (CDNC) over the SWA domain. Also, an increase of 12.45% in Particulate Matter (PM25) surface concentration was observed in Abidjan (9.75 μg m−3), Accra (10.7 μg m−3), Cotonou (10.7 μg m−3), and Lagos (8 μg m−3), while the carbon monoxide (CO) mixing ratio increased by 90 ppb in Abidjan and Accra due to BB. Moreover, BB aerosols were found to contribute to a 70% increase of organic carbon (OC) below 1 km in the PBL, followed by black carbon (BC) with 24.5%. This work highlights the contribution of the long-range transport of BB pollutants to pollution levels in SWA and their effects on the climate. It focuses on a case study of 3 days (5–7 July 2016). However, more research on a longer time period is necessary to inform decision making properly.This study emphasizes the need to implement a long-term air quality monitoring system in SWA as a method of climate change mitigation and adaptation.

Published: May 2021

AbstractClimate change impact on rainfall and temperature extreme indices in the Vea catchment was analyzed using observation and an ensemble mean of bias-corrected regional climate models datasets for Representative Concentration Pathway (RCP 4.5) scenario. Rainfall extreme indices such as annual total wet-day precipitation (PRCPTOT), extremely wet days (R99P), consecutive wet days (CWD), consecutive dry days (CDD), and temperature indices such as warmest day (TXx) and warmest night (TNx) from the Expert Team on Climate Change Detection Monitoring Indices (ETCCDMI) were computed for both the historical (1986–2016) and future (2020–2049) period using the RClimdex. The parametric ordinary least square (OLS) regression approach was used to detect trends in the time series of climate change and extreme indices. The results show an increase in mean annual temperature at the rate of 0.02 °C/year and a variability in rainfall at the catchment, under RCP 4.5 scenario. The warmest day and warmest night were projected to increase by 0.8 °C and 0.3 °C, respectively, in the future relative to the historical period. The intensity (e.g., R99p) and frequency (e.g., CDD) of extreme rainfall indices were projected to increase by 29 mm and 26 days, respectively, in the future. This is an indication of the vulnerability of the catchment to the risk of climate disasters (e.g., floods and drought). Adaptation strategies such as early warning systems, availability of climate information, and flood control measures are recommended to reduce the vulnerability of the people to the risk of the projected impact of climate extreme in the future.
ECMWF Subseasonal to Seasonal Precipitation Forecast for Use as a Climate Adaptation Tool Over Nigeria
Authors: Akeh Ugbah Paul , Woolnough Steve , Olaniyan Olumide A. 
Published: May 2021

AbstractFarmers in most parts of Africa and Asia still practice subsistence farming which relies minly on seasonal rainfall for Agricultural production. A timely and accurate prediction of the rainfall onset, cessation, expected rainfall amount, and its intra-seasonal variability is very likely to reduce losses and risk of extreme weather as well as maximize agricultural output to ensure food security.Based on this, a study was carried out to evaluate the performance of the European Centre for Medium-range Weather Forecast (ECMWF) numerical Weather Prediction Model and its Subseasonal to Seasonal (S2S) precipitation forecast to ascertain its usefulness as a climate change adaptation tool over Nigeria. Observed daily and monthly CHIRPS reanalysis precipitation amount and the ECMWF subseasonal weekly precipitation forecast data for the period 1995–2015 was used. The forecast and observed precipitation were analyzed from May to September while El Nino and La Nina years were identified using the Oceanic Nino Index. Skill of the forecast was determined from standard metrics: Bias, Root Mean Square Error (RMSE), and Anomaly Correlation Coefficient (ACC).The Bias, RMSE, and ACC scores reveal that the ECMWF model is capable of predicting precipitation over Southern Nigeria, with the best skill at one week lead time and poorest skills at lead time of 4 weeks. Results also show that the model is more reliable during El Nino years than La-Nina. However, some improvement in the model by ECMWF can give better results and make this tool a more dependable tool for disaster risk preparedness, reduction and prevention of possible damages and losses from extreme rainfall during the wet season, thus enhancing climate change adaptation.
The Multifaceted Glioblastoma: From Genomic Alterations to Metabolic Adaptations
Authors: Quinones Addison , Le Anne 
Published: May 2021

AbstractGlioblastoma multiforme (GBM) develops on glial cells and is the most common as well as the deadliest form of brain cancer. As in other cancers, distinct combinations of genetic alterations in GBM subtypes induce a diversity of metabolic phenotypes, which explains the variability of GBM sensitivity to current therapies targeting its reprogrammed metabolism. Therefore, it is becoming imperative for cancer researchers to account for the temporal and spatial heterogeneity within this cancer type before making generalized conclusions about a particular treatment’s efficacy. Standard therapies for GBM have shown little success as the disease is almost always lethal; however, researchers are making progress and learning how to combine therapeutic strategies most effectively. GBMs can be classified initially into two subsets consisting of primary and secondary GBMs, and this categorization stems from cancer development. GBM is the highest grade of gliomas, which includes glioma I (low proliferative potential), glioma II (low proliferative potential with some capacity for infiltration and recurrence), glioma III (evidence of malignancy), and glioma IV (GBM) (malignant with features of necrosis and microvascular proliferation). Secondary GBM develops from a low-grade glioma to an advanced-stage cancer, while primary GBM provides no signs of progression and is identified as an advanced-stage glioma from the onset. The differences in prognosis and histology correlated with each classification are generally negligible, but the demographics of individuals affected and the accompanying genetic/metabolic properties show distinct differentiation [3].
Introduction
Authors: Greiner Rasmus 
Published: May 2021

AbstractThis chapter introduces the term histosphere to refer to the “sphere” of a cinematically modeled, physically experienceable historical world. The prefix “histo-” denotes here not just (popular conceptions of) history, but also a particular bodily dimension. In the phenomenological space between audiovisual figurations and historical experience, a histosphere functions—in the manner of histology—as an innervated tissue that relays the potential semiotic meanings of the cinematically constructed past via physical-sensory stimuli. Against the general assumption that the constitutive feature of historical films is that they represent history, it is instead their audiovisual modeling and figuration of a historical world, which enables an immediate experience of history.
Immersion and Empathy
Authors: Greiner Rasmus 
Published: May 2021

AbstractThe aim of this chapter is to investigate histospheres as multi-immersive perceptual spaces that not only model a historical world but also profoundly influence our conceptions and interpretations of history. In this context, the first section examines the role of aesthetically modeled atmospheres and the moods they evoke. The second section builds on this examination by considering filmic space.Filmic atmospheresand spatial figurations of movement bring us physically and mentally closer to the action of the film. Another potent mechanism of perspectivation is film characters, and so the third section focuses onimaginative empathywith the characters who inhabit a film’s historical world. In combination with film experience as a mode ofembodied perception, this inner perspective provokes interpretations and evaluations that we can extend to the filmic depiction’s historical references.

AbstractIn this chapter we lay out the primary background of a financial opinion and the relation between opinions and financial instruments. Together, these constitute an overall picture of opinion-based market interaction. Following this discussion we propose several research issues. First, in Sect. 2.1, we discuss the components in a financial opinion one by one, as well as potential research directions; we also explain why we need to extract components and estimate their quality (or influence).
