There is no doubt that today, perhaps more than ever before, humanity faces a myriad of complex and demanding challenges. These include natural resource depletion and environmental degradation, food and water insecurity, energy shortages, diminishing biodiversity, increasing losses from natural disasters, and climate change with its associated potentially devastating consequences, such as rising sea levels. These human-induced and natural impacts on the environment need to be well understood in order to develop informed policies, decisions, and remedial measures to mitigate current and future negative impacts. To achieve this, continuous monitoring and management of the environment to acquir...
Kenya is a thriving country in East Africa: its economy is largely based on the natural environment that frames the tourism sector, mainly through safaris and holidays on the coast. The natural environment also underpins the second largest industry: agriculture. Kenya's social, technological, and industrial developments are a reference for many neighboring countries. Kenya plays a leading role in Africa and attracts huge amounts of investments. Furthermore, the humanitarian community has made Nairobi its base for international headquarters and regional offices. This makes Kenya a possible model for development and investment in its widest sense. This book aims at updating the holistic view o...
This second edition includes updated chapters from the first edition as well as five additional new chapters (Light detection and ranging (LiDAR), CORONA historical de-classified products, Unmanned Aircraft Vehicles (UAVs), GNSS-reflectometry and GNSS applications to climate variability), shifting the main focus from monitoring and management to extreme hydro-climatic and food security challenges and exploiting big data. Since the publication of first edition, much has changed in terms of technology, and the demand for geospatial data has increased with the advent of the big data era. For instance, the use of laser scanning has advanced so much that it is unavoidable in most environmental mo...
This chapter begins with a synopsis of the basic concept of remote sensing with the various stages and interactions that characterize the entire remote sensing process described. A brief recapitulation of the status of stored water in Kenya is then presented. The monumental challenge facing many poor Kenyan households in accessing clean and safe water in sufficient quantities is reiterated. The chapter underscores the critical value of accurate and timely geospatial and hydro-meteorological datasets in supporting integrated water resources management. It is argued that the availability of techniques that deliver information on the changes in stored water at a more local scale is the first step towards realizing an efficient water society. Finally, two case studies that employ diverse remote sensing datasets to provide an evidence based explanation of the decline in stored water in Lakes Victoria and Naivasha are elucidated.
"This book provides relevant theoretical frameworks and empirical research findings in the area hydroinformatics to assist professionals to improve their understanding of the development and use of decision support tools to support decision making and integrated water management at different organizational levels and domains"--Provided by publisher.
Currently the writing on the subject is limited and comprises, for the most part, guidance documents and completed assessments.
Green Technologies: Concepts, Methodologies, Tools and Applications assembles the most up-to-date collection of research results and recent discoveries in environmental and green technology. This comprehensive anthology covers a wide range of topics, i
The versatile and available GNSS signals can detect the Earth’s surface environments as a new, highly precise, continuous, all-weather and near-real-time remote sensing tool. This book presents the theory and methods of GNSS remote sensing as well as its applications in the atmosphere, oceans, land and hydrology. Ground-based atmospheric sensing, space-borne atmospheric sensing, reflectometry, ocean remote sensing, hydrology sensing as well as cryosphere sensing with the GNSS will be discussed per chapter in the book.
Developed countries, especially in Europe, face a number of issue related to migration: social and economic disruptions caused by the declining demand for unskilled labour and resulting unemployment, a shortage of skilled labour in many professions, increasing international competition for highly qualified human capital, radical demographic changes, and the forthcoming expansion of the European Union, which will trigger further immigration into major European countries and create new market opportunities in Central and Eastern Europe. This suggests a need for a deeper knowledge of the causes and consequences of increased labour mobility. This is especially important when it is associated wit...
