The proceedings book of the Global Symposium on Soil Erosion (GSER19) contains all papers presented both orally and in poster format during the symposium (15-17 May 2019, FAO HQ). The papers presented have provided sufficient scientific evidence to show that soil erosion is a global threat to food production systems, available land for future demand, rural livelihoods, human health and biodiversity, and that coordinated effective action needs to be fostered and accelerated to address this issue. Studies presented provided scientific evidence that soil erosion is accelerated by anthropogenic action. In the current context of population increase and climate change, urgent action is needed from governments to support farmers and land-users in the transition to sustainable production systems, and crucial action is needed at global level to raise awareness of the importance of healthy and productive soils, to ensure a sustainable future and the achievement of many of the SDGs targeting hunger, water quality, and life on land, amongst others.

Despite almost a century of research and extension efforts, soil erosion by water, wind and tillage continues to be the greatest threat to soil health and soil ecosystem services in many regions of the world. Our understanding of the physical processes of erosion and the controls on those processes has been firmly established. Nevertheless, some elements remain controversial. It is often these controversial questions that hamper efforts to implement sound erosion control measures in many areas of the world. This book, released in the framework of the Global Symposium on Soil Erosion (15-17 May 2019) reviews the state-of-the-art information related to all topics related to soil erosion.

This book provides guidelines for using a new approach of resampling the Cs-137 radionuclide tracer which is used to estimate soil erosion rates. The Cs-137 resampling approach will improve significantly the use of the Cs-137 method for assessment of soil erosion, because resampling the radionuclide repeatedly (at least two times, but more sampling campaigns are possible) allows to avoid several methodological difficulties associated with Cs-137 method, namely the problems with small-scale spatial heterogeneity, the question of representativeness of reference site, reference samples, and inappropriate time extent of evaluated period. All these methodological problems are very important for reliability and accuracy of erosion rates estimated by Cs-137 method. If using single sampling approach, the small-scale spatial heterogeneity can be overcome by high number of sampling points, but this is time and labour demanding solution increasing the expenses of the erosion research. The representativeness of reference site is evaluated usually on the basis of expert judgement and knowledge of land use history of studied area, but this approach is often uncertain because the expert judgement can be subjective and the data on land use history is often not sufficient. Further, in many areas an appropriate reference site is not available, what limits the territorial extent of using Cs-137 method. The resampling approach offers its second sampling to be done in a proximate vicinity of the same points sampled during the first sampling campaign. A great advantage is the possibility to decide how long time windows should be investigated. Choosing the time schedule of first and second sampling allows to shorten the time window and adjust it to the study objectives. This is a great improvement of the Cs-137 method, because the time period since the Cs-137 fallout is still growing and thus if using the single sampling approach the results refer to still longer and longer time window(since the Cs-137 fallout until the sampling time), and this period (recently ca 60 years assuming the maximum Cs-137 fallout in 1963) is too long to represent stable land use, because land uses are changing over the time and having the same land use over six decades is rather rare. The improvement of Cs-137 method achieved by resampling approach is significantly contributing to understanding the erosion dynamics and estimating its rates under changing environmental conditions (such as land uses, weather), and it will bring a significant benefit to soil conservation programmes, because Cs-137 method is indispensable for assessing the medium and long term soil erosion rates, and this information is among the basic inputs needed for planning and designing soil conservation measures.

The changing focus and approach of geomorphic research suggests that the time is opportune for a summary of the state of discipline. The number of peer-reviewed papers published in geomorphic journals has grown steadily for more than two decades and, more importantly, the diversity of authors with respect to geographic location and disciplinary background (geography, geology, ecology, civil engineering, computer science, geographic information science, and others) has expanded dramatically. As more good minds are drawn to geomorphology, and the breadth of the peer-reviewed literature grows, an effective summary of contemporary geomorphic knowledge becomes increasingly difficult. The fourteen volumes of this Treatise on Geomorphology will provide an important reference for users from undergraduate students looking for term paper topics, to graduate students starting a literature review for their thesis work, and professionals seeking a concise summary of a particular topic. Information on the historical development of diverse topics within geomorphology provides context for ongoing research; discussion of research strategies, equipment, and field methods, laboratory experiments, and numerical simulations reflect the multiple approaches to understanding Earth’s surfaces; and summaries of outstanding research questions highlight future challenges and suggest productive new avenues for research. Our future ability to adapt to geomorphic changes in the critical zone very much hinges upon how well landform scientists comprehend the dynamics of Earth’s diverse surfaces. This Treatise on Geomorphology provides a useful synthesis of the state of the discipline, as well as highlighting productive research directions, that Educators and students/researchers will find useful. Geomorphology has advanced greatly in the last 10 years to become a very interdisciplinary field. Undergraduate students looking for term paper topics, to graduate students starting a literature review for their thesis work, and professionals seeking a concise summary of a particular topic will find the answers they need in this broad reference work which has been designed and written to accommodate their diverse backgrounds and levels of understanding Editor-in-Chief, Prof. J. F. Shroder of the University of Nebraska at Omaha, is past president of the QG&G section of the Geological Society of America and present Trustee of the GSA Foundation, while being well respected in the geomorphology research community and having won numerous awards in the field. A host of noted international geomorphologists have contributed state-of-the-art chapters to the work. Readers can be guaranteed that every chapter in this extensive work has been critically reviewed for consistency and accuracy by the World expert Volume Editors and by the Editor-in-Chief himself No other reference work exists in the area of Geomorphology that offers the breadth and depth of information contained in this 14-volume masterpiece. From the foundations and history of geomorphology through to geomorphological innovations and computer modelling, and the past and future states of landform science, no "stone" has been left unturned!

Africa can achieve self sufficiency in food production through adoption of innovations in the agriculture sector. Numerous soil fertility and crop production technologies have been generated through research, however, wide adoption has been low. African farmers need better technologies, more sustainable practices, and fertilizers to improve and sustain their crop productivity and to prevent further degradation of agricultural lands. The agricultural sector also needs to be supported by functional institutions and policies that will be able to respond to emerging challenges of globalization and climate change.

Tillage agriculture has led to widespread soil and ecosystem degradation globally, and more particularly in the developing regions. This is especially so in Africa where traditional agricultural practices have become unsustainable due to severe exploitation of natural resources with negative impacts on the environment and food system. In addition, agricultural land use in Africa today faces major challenges including increased costs, climate change and a need to transform to more sustainable production intensification systems. Conservation Agriculture has emerged as a major alternative sustainable climate smart agriculture approach in Africa and has spread to many African countries in the past decade as more development and research, including in sustainable mechanization, has enabled its extension and uptake. It is key to transforming Africa's agriculture and food system given its ability to restore soil health, biodiversity and productivity of millions of smallholder farms as well as larger-scale farms. This book is aimed at all agricultural stakeholders in the public, private and civil sectors in Africa engaged in supporting the transformation of conventional tillage agriculture to Conservation Agriculture. The book will be of interest to: researchers, academics, students, development stakeholders, public and private sector investors and policy makers as well as institutional libraries across the world.
