Groundwater is Africa's most precious natural resource, providing reliable water supplies for many people. Further development of groundwater resources is fundamental to increasing access to safe water across the continent to meet coverage targets and reduce poverty. There is also an increasing interest in the use of groundwater for irrigated agriculture as the climate becomes more variable. Sustainable development of the resource is not a trivial task and depends crucially on an understanding of the hydrogeology and people with the skills to make informed decisions on how groundwater can best be developed and managed in a sustainable fashion. Despite these obvious needs, however, little attention has been paid to the systematic gathering of information about groundwater resources in the past few decades, with the result that data are patchy, knowledge is limited and investment is poorly targeted.This book was written to start to bridge the knowledge gap. The 29 chapters are written by a combination of practitioners and researchers mainly from within Africa using experience from recent and ongoing projects. The chapters highlight the complexity and variety of issues surrounding the development and management of groundwater resources across Africa, and provide a snapshot of groundwater research and application in the early 21st century. Chapters range from strategic discussions of the role of groundwater in development and poverty reduction, to case studies on techniques used to develop groundwater, and modelling methods for managing groundwater systems.

Wetlands are too often perceived as standalone elements and are poorly integrated into river basin management. The Ramsar Convention recognizes the critical linkage between wetlands, water and river basin management; the governments that are party to the Convention have committed to conserving their wetlands within a framework of Integrated Water Resources Management (IWRM). The “Critical Path” approach and related guidance have been adopted by Contracting Parties of the Ramsar Convention in order to effectively integrate wetland conservation and management into river basin management planning and decision-making. However, despite international acceptance of the approach, it is not widely implemented. This paper provides one of the first case study based assessments of the Critical Path approach. The analysis of two contrasting Ramsar sites is presented in order to better understand the barriers to implementation in different development contexts. These are the Lobau wetland in Austria, where management institutions and regulatory frameworks are highly developed; and the Inner Niger Delta in Mali, where the capacity to implement IWRM is less evolved. A planning approach is proposed which involves structured and transparent methods for assessing ecosystem services and institutional capacity, and is suitable as a tool for identifying, prioritizing and negotiating trade-offs in ecosystem services and improving livelihoods. Based on the analysis, two main barriers to implementation are identified; mismatch between local and national or basin level priorities, and a lack of recognition of the ecosystem services provided by wetlands.

One of the main challenges of hydrological modeling is the poor spatiotemporal coverage of in situ discharge databases which have steadily been declining over the past few decades. It has been demonstrated that water heights over rivers from satellite altimetry can sensibly be used to deal with the growing lack of in situ discharge data. However, the altimetric discharge is often estimated from a single virtual station suffering from coarse temporal resolution, sometimes with data outages, poor modeling and inconsistent sampling. In this study, we propose a method to estimate daily river discharge using altimetric time series of an entire river basin including its tributaries. Here, we implement a linear dynamic model to (1) provide a scheme for data assimilation of multiple altimetric discharge along a river; (2) estimate daily discharge; (3) deal with data outages, and (4) smooth the estimated discharge. The model consists of a stochastic process model that benefits from the cyclostationary behavior of discharge. Our process model comprises the covariance and cross-covariance information of river discharge at different gauges. Combined with altimetric discharge time series, we solve the linear dynamic system using the Kalman filter and smoother providing unbiased discharge with minimum variance. We evaluate our method over the Niger basin, where we generate altimetric discharge using water level time series derived from missions ENVISAT, SARAL/AltiKa, and Jason-2. Validation against in situ discharge shows that our method provides daily river discharge with an average correlation of 0.95, relative RMS error of 12%, relative bias of 10% and NSE coefficient of 0.7. Using a modified NSE-metric, that assesses the non-cyclostationary behavior, we show that our estimated discharge outperforms available legacy mean daily discharge.

Climate change and its impacts on agriculture have been widely discussed at national and global levels. An important aspect of the discussion has been adaptation/mitigation approaches. Consequently, several strategies have been suggested as measures to ensure agriculture remains productively profitable. However, food security especially in critical times, such as the lockdown during the COVID-19 pandemic proved to be a challenge even for regions naturally endowed for agriculture. The study evaluated research recommended strategies, and further examined the innovativeness of the strategies in fostering sustainable agricultural innovation system (AIS) in the Niger Delta. The study relied on both secondary and primary data; analysed 129 previous studies and gathered responses from 282 extension agents. The study introduces a method for assessing the innovativeness of strategies by calculating their rated values on five traits. Findings revealed the issues and implications of adopting most recommended strategies and the place of most strategies in fostering AIS. The study highlights the possible reasons why farmers fail to adopt most strategies as suggested by studies on climate change in the region. Based on the findings, recommendations were made on the way forward. The study adds to the scanty discussion of climate change and AIS at regional levels, particularly in the climate change prone and oil rich Niger Delta region. The study offers a novel approach for scoring innovations in agriculture.
