This book focuses on the issues of soil erosion and sediment dynamics in the Siwalik Hills of Nepal Himalaya.

Study of different kinds of plants, soil and climate and the quantitative analysis of vegetation structure and composition at the three VDCs of Siwalik hills of Ilam was undertaken. A total of 137 flowering plants and 9 pteridophytes belonging to 27 families of trees, 31 families of shrubs, 27 families of herbs and 7 families of ferns are reported. The tree diversity value was highest (2.235) from matured forests of Danabari (Sector II) and the least (2.021) from the regenerating forest of Chulachuli (Sector II). However, the species evenness was highest in sector III for shrub (0.183) and herb (0.128). The tree trunk volume was maximum (413623.13 m2ha-1) in case of matured forest at Danabari (Sector II). Shorea robusta, Terminalia alata and Semecarpus anacardium were the most dominant species in the entire study area. Sector I had the highest shrub and herb density of 1600 pl. ha-1 for Desmodium confertum and 4285.7 pl. ha-1 for Ageratum hustonianum respectively. Sector II has northern aspect and due to more precipitation record has rendered the land remain wet. The tree species of Semecarpus anacardium, Schima wallichi, some species of orchids along with various leguminous plants were recorded. The south facing sectors I and II were drier with more records of degraded land. The similarity index of tree species found in sectors I and II was recorded high (36.36). Soil present in sector III was found to be more acidic (pH 5.6). Organic matter and nitrogen content was higher in sectors II than that of sector I and III. Highest percolation capacity was found in the soil of sector I. Organic matter was positively correlated with nitrogen at the 0.05 level. As a whole, the vegetation was much more encouraging ecologically than expected from a distant observation.

“Applied Morphometry and Watershed Management” book is designed to introduce the recent developments related to applied morphometric studies of drainage basins. Applications of drainage basin morphometric analysis cover several topics of research such as: 1) Prioritization of sub-watersheds for soil and water conservation; 2) Surface water harvesting; 3) Assessment of groundwater potential and predicting of groundwater movement; 4) Geo-hazard assessment (i.e., soil erosion and sediment yield modeling, landslide susceptibility mapping; flashflood hazard and flood management; 5) The impact of Quaternary tectonics on structure and drainage network distortions.

"Upholding the high standard of quality set by the previous edition, this two-volume second edition offers a vast array of recent peer-reviewed articles. It showcases research and practices with added sections on ISTIC-World Soil Information, root growth and agricultural management, nitrate leaching management, podzols, paramos soils, water repellant soils, rare earth elements, and more. With hundreds of entries covering tillage, irrigation, erosion control, ground water, and soil degradation, the book offers quick access to all branches of soil science, from mineralology and physics, to soil management, restoration, and global warming."--Publisher's website.

This book offers a systematic investigation of the ecological and environmental issues related to the land cover changes in Nepal by researchers from both China and Nepal. It discusses the eco-environmental issues faced by Nepal, particularly in the hills and mountain regions. It also sheds light on the global concerns regarding the eco-environment issues of mountains, and analyzes the various causes and potential consequences of eco-environmental degradation in Nepal. The book is of particular interest to students, researchers, experts, and decision-makers wanting to gain a general overview of land cover in Nepal and its dynamics, environment and natural resources, as well as mountain hazards.

This book deals with the state of the art and policy issues for the sustainable management of the eco-system of Himalayan countries, and focuses on the mechanisms and technologies, acceptable to the communities of the region. It contains enhanced research accounts and essays from eminent environmentalists of the region who have vast experience and knowledge behind them.
