Book Description
This book employs a suite of remotely sensed products and advanced technologies to provide the first comprehensive space-based sensing of Lake Victoria, the world’s second largest freshwater lake that supports a livelihood of more than 42 million people, modulates regional climate, but faces myriads of challenges. Proper understanding of the lake and changes in its physical dynamics (e.g., water level, shorelines and areal dynamics) resulting from the impacts of climate variation and climate change as well as anthropogenic (e.g., hydropower and irrigation) is important for its management as well as for strategic development before, during and after climate extremes (e.g., floods and droughts) in order to inform policy formulations, planning and mitigation measures. Owing to its sheer size, and lack of research resources commitment by regional governments that hamper its observations, however, it is a daunting task to undertake studies on Lake Victoria relying solely on in-situ “boots on the ground” measurements, which are sparse, missing in most cases, inconsistent or restricted by governmental red tapes. To unlock the potentials of Lake Victoria, this book argues for the removal of obsolete Nile treaties signed between Britain, Egypt and Sudan in the 1920s and 1950s, which prohibits its utilization by the upstream countries. The book is useful to those in water resources management and policy formulations, hydrologists, environmentalists, engineers and researchers. In a unique cross-disciplinary approach, the Book articulates the various climatic impacts and explanations from natural and anthropogenic origins, which affected Lake Victoria and its vicinity, including the drastic increase and depletion of water level in the Lake and dams, floods and droughts, water quality/security, crop health, food security, and economic implications. With no exception as in his many publications, Joseph L. Awange used data analysis methodologies including filtering, adjustment theory, and robust statistics, to quantify the hydrologic and other parameters, and their estimated uncertainties. The Book is recommended for readers from a diverse disciplines, including physical and social sciences, policy, law, engineering, and disaster management. Professor C.K. Shum, Ohio State University.

Book Description
This book is useful to those in water resources management and policy formulations, hydrologists, environmentalists, engineers and researchers. Exploiting advanced statistical techniques and the latest state-of-the-art multi-mission satellites, surface models and reanalysis products, this book provides the first comprehensive weighing of the changes in the Nile River Basin’s (NRB: ~ 3,400,000 km2 ) stored waters' compartments, surface, soil moisture and groundwater, and their association to climate variability/change and anthropogenic impacts on the one hand. On the other hand, it argues on the need for equitable use of the NRB’s waters by all 11 countries within its basin, and doing away with obsolete Nile treaties that were signed by Britain, Egypt and Sudan, which prohibit the use of the Nile by 8 upstream countries. With Ethiopia’s construction of Africa’s largest dam (GERD; Grand Ethiopian Renaissance Dam) along the Blue Nile, which is expected to take several years to fill, the Nile is back on the news. Combined with Uganda’s Nalubaale, Kiira and Bujagali dams on the White Nile, these human-induced impacts (i.e., damming), coupled with those of climate variability/change, are expected to exacerbate tension with the low stream countries (Egypt and Sudan) fearing the cut in theNile’s total volume. Furthermore, the Nile river, arguably the world’s longest river (6800 km), impacts on the livelihood of over 300 million people of 11 countries within its basin. This population is expected to double in the next twenty-five years, thereby putting extreme pressure on its water resources. An in-depth analysis of changes in the Nile’s stored waters, therefore, is essential to inform its management and sustainable equitable use. Owing to its sheer size, however, obtaining in-situ data from “boots on the ground” is practically impossible, paving way to the space-based weighing of the Nile River Basin using a suite of high spatio-temporal remotely sensed and reanalysis products, as well as those of hydrological models. “Arguably, the Nile River is the most unique river in the world. It spans extremes of rainfall from being measured by meters to being measured by centimeters, from the humid tropics to the driest of deserts. Yet, thirsty people live throughout this basin and therefore the demands on its water resources are uneven. Knowing the water amounts throughout the entire Nile Basin is a critical step for governments and international treaties to avoid the “Tragedy of the Commons”. Africa can embrace this future through the leadership of Prof. Awange and others like him who have devoted their careers to Africa’s waters” —Doug Alsdorf, Ph.D., Professor of Geophysics at the Ohio State University (USA).

Book Description
This book will benefit users in food security, agriculture, water management, and environmental sectors. It provides the first comprehensive analysis of Greater Horn of Africa (GHA)’s food insecurity and hydroclimate using the state-of-the-art Gravity Recovery and Climate Experiment (GRACE) and its Follow-on (GRACE-FO)’s, centennial precipitation, hydrological models’ and reanalysis’ products. It is here opined that GHA is endowed with freshwater (surface and groundwater) being home to the world's second largest freshwater body (Lake Victoria) and the greatest continental water towers (Ethiopian Highlands) that if properly tapped in a sustainable way, will support its irrigated agriculture as well as pastoralism. First, however, the obsolete Nile treaties that hamper the use of Lake Victoria (White Nile) and Ethiopian Highland (Blue Nile) have to be unlocked. Moreover, GHA is bedevilled by poor governance and the ``donor-assistance” syndrome; and in 2020-2021 faced the so-called ``triple threats’’ of desert locust infestation, climate variability/change impacts and COVID-19 pandemic. Besides, climate extremes influence its meagre waters leading to perennial food insecurity. Coupled with frequent regional and local conflicts, high population growth rate, low crop yield, invasion of migratory pests, contagious human and livestock diseases (such as HIV/AIDs, COVID-19 & Rift Valley fever) and poverty, life for more than 310 million of its inhabitants simply becomes unbearable. Alarming also is the fact that drought-like humanitarian crises are increasing in GHA despite recent progress in its monitoring and prediction efforts. Notwithstanding these efforts, there remain challenges stemming from uncertainty in its prediction, and the inflexibility and limited buffering capacity of the recurrent impacted systems. To achieve greater food security, therefore, in addition to boosting GHA's agricultural output, UN Office for the Coordination of Humanitarian Affairs suggest that its “inhabitants must create more diverse and stable means of livelihood to insulate themselves and their households from external shocks”. This is a task that they acknowledge will not be easy as the path ahead is “strewn with obstacles namely; natural hazards and armed conflicts”. Understanding GHA’s food insecurity and its hydroclimate as presented in this book is a good starting point towards managing the impacts of the natural hazards on the one hand while understanding the impacts associated with extreme climate on GHA's available water and assessing the potential of its surface and groundwater to support its irrigated agriculture and pastoralism would be the first step towards “coping with drought” on the other hand. The book represents a significant effort by Prof Awange in trying to offer a comprehensive overview of the hydroclimate in the Greater Horn of Africa (GHA). Prof Eric F. Wood, NAE (USA); FRSC (Canada); Foreign member, ATSE (Australia).

Book Description
Global Navigation Satellite Systems (GNSS) are revolutionizing the world in a way their original developers never envisaged. From being military “war” tools, GNSS satellites are rapidly becoming “peace” tools that play a potentially critical role in enabling changing environmental phenomenon that do not permit direct measurements to be remotely observed via their all-weather, highly accurate and continuously updatable positional time series. This is evident, for example, in their use in emerging environmental monitoring methods that are considered in this book. These include: GPS-based radio telemetry, which is enhancing ecological and conservation monitoring by more accurately mapping animal movements, their behaviours, and their impact on the environment; GNSS-meteorology, which is contributing to weather and climate change studies; GNSS-remote sensing, which, for example, allows the rapid monitoring of changes in fresh water resources and cryosphere; Geosensor network techniques, which are earning a crucial role in disaster response management; Epidemiology, for improved efficiency in tracking and studying the spread of infectious diseases and climate change effects on vector-borne diseases; and Economics, to provide data for the econometric modelling of casual impact of policies. In Environmental Impact Assessments (EIA), Strategic Environmental Assessments (SEA), and Sustainability Assessments (SA), GNSS, together with other spaced-based remote sensing techniques, are emerging, not only as modern tools that connect the developers to the community, but also provide information that support Multi-Criteria Analysis (MCA) methods, which inform decision making and policy formulations. By bringing the two fields of geodesy (the parent of GNSS technology) and environmental studies (potential users of this technology), this book presents the concepts of GNSS in a simplified way that can, on the one hand, be understood and utilised by environmentalists, while on the other, outlines its potential applications to environmental monitoring and management for those engaged more with its technology, which hopefully will further energise the already innovative research that is being carried out. Lastly, this book is most relevant to all the professionals whose work is related to the environment such as hydrologists, meteorologists, epidemiologists, economist, and engineers, to name just a few. A comprehensive yet candid and compelling presentation of Global Navigation Satellite Systems and its application to environmental monitoring and a host of other socio-economic activities. This is an essential and new ground breaking reading for all professional practitioners and even academics seeking to study and become involved in using Global Navigation Satellite Systems in diverse fields ranging from environmental monitoring to economic activities such as monitoring weather and climate in order to design crop failure insurance.

Book Description
The African Seas include marginal basins of two major oceans, the Atlantic and the Indian, a miniature ocean, the Mediterranean Sea, and an infant ocean, the Red Sea. Understanding the wide spectrum of environmental features and processes of such a varied collection of marine and coastal regions requires that in situ observation systems be integrated and actually guided, by the application of orbital remote sensing techniques. This volume reviews the current potential of Earth Observations to help in the exploration of the marginal seas around Africa, by virtue of both passive and active techniques, working in several spectral ranges – i.e. measuring either reflected visible and near-infrared sunlight, as well as surface emissions in the thermal infrared and microwave spectral regions, or again the surface reflection of transmitted lidar or radar impulses of visible or microwave radiation. The in-depth evaluation of the advantages offered by each technique and spectral region and in particular by the development of advanced multi-technique systems, contributes to the assessment of the abundant natural resources that the Seas of Africa have to offer, of those in dear need of being – sustainably – exploited and of others that should be protected and maintained in their still pristine conditions.
