“…Loads were found to have declined at most gauging stations at an average rate of −1.17% per year, but the downward trend was not linear nor continuous and in detail varied with catchment altitude, area, and fraction of cropland. Goharrokhi et al (2022) utilized records extending over more than 40 years to elucidate changes in sediment loads in large regulated rivers in the subarctic region of Canada and to contrast the effects of climate change and river diversions. An increase in sediment load of 155% in the Upper Nelson River between the periods 1979–1998 and 1999–2019 was found to reflect climate change which increased water discharge across the whole catchment, and an increase in sediment erosion downstream of Lake Winnipeg.…”

Walling wrote his first papers about suspended sediment in Devon river catchments as a young hydrologist more than 50 years ago in the early 1970s. In those days, some very senior scientists told him he was wasting his time, because soil erosion in Britain was not a problem, and British rivers were not muddy! A half a century, and more than 500 publications (the majority of which are devoted to fine sediment in river catchments) later, Des is regarded as one of the world's leading hydrologists who have focused on erosion and sediment yields and catchment sediment budgets. His prolific, distinguished and frequently highly-cited research contributions have been recognized by important awards including the IAHS/UNESCO/ WMO International Hydrology Prize, the American Geophysical Union Hydrologic Sciences Award, the Norman Hudson Memorial Award of the World Association of Soil and Water Conservation, the Chien Ning International Prize of the World Association for Sedimentation and Erosion Research and the Victoria Medal of the Royal Geographical Society. Des has advocated eloquently and powerfully that sediment studies have an important role within the discipline of hydrology, not only because of the implications for environmental protection and sustainable development, but also because fine sediment represents a key pathway for material transport at all scales ranging from the individual farmer's field to the global earth system. In order to underpin his work, Des established an intensive programme of field investigations through a network of long-term measuring sites in the local Exe basin, which operated for over 30 years. He also developed complementary high quality laboratory facilities in the Geography Department at the University of Exeter for studying sediment properties, including one of the best-equipped gamma spectrometry laboratories in the world. However, he was also keen to extend the canvas on which he worked beyond the local to the national and the international. Such activity has seen him conducting soil loss studies across several areas of Britain and investigating the delivery of sediment through larger river systems including the River Severn and the Yorkshire Ouse. He has also carried out much work overseas in North, East and Southern Africa,

“…The Indigenous community under study use riparian areas for planting due to their higher productivity and because they claim that the crops do not deteriorate as quickly as those in other cultivation areas. In fact, these areas have the greatest capacity for nutrient recovery due to the hydrosedimentological processes that occur in the river [59].…”

The identification and analysis of mythical images and ancestral practices that make up the ethnos of a community allow us to know its ways of existing in the cosmos. The objective of this paper is to analyze the ancestral experiences associated with the dynamics of socio-environmental management that the Emberá Indigenous reserve (Chocó, Colombia) carries out for the conservation of water and land. This study is qualitative and ideographic. We also adopted an ethnographic approach to provide a detailed description of water and land management practices, which correspond to their cultural patterns. Using Atlas Ti V.6.0 software, we identify and analyze these cultural patterns. The results show that the ecosystemic relationships offered by the Emberá worldview are part of a true connection with their spiritual world, which fosters respect for the natural elements and understanding of universal natural laws. These relationships are manifested through gifts and penance. The Emberá beliefs and religion are a possible methodology for the sustainable management of water and land and, consequently, of the basin where they live. The success of their ethnodevelopment depends significantly on the power figures of their culture: the Jaibana (their gods), the elders, and the Emberá woman as a cultural agent. The Emberá worldview is possibly a valid instrument to enable the sustainable development of modern communities.
