Integrated Management of Salt Affected Soils in Agriculture is a
concise guide to evaluating and addressing soil issues related to
saline content. Methods focused, the book combines agricultural and
soil-based insights to efficiently remediate salt-affected soil.
Environmental stress conditions such as salinity have a devastating
impact on plant growth and yield, causing considerable loss to
agricultural production worldwide. Soil salinity control prevents
soil degradation by salinization and reclaim already saline soils.
This book will help develop the proper management procedures, to
solve problems of crop production on salt-affected soils.

The critically acclaimed serialized review journal for over 50
years, Advances in Geophysics is a highly respected publication in
the field of geophysics. Since 1952, each volume has been eagerly
awaited, frequently consulted, and praised by researchers and
reviewers alike. Now in its 56th volume, it contains much material
still relevant today--truly an essential publication for
researchers in all fields of geophysics.
Shale Gas and Fracking: The Science Behind the Controversy explains
the relevant geological principles before examining the
peer-reviewed evidence and presenting it through a simple and
compelling illustrated narrative. Each chapter focuses on a
particular controversy, such contamination of well water with gas
from fracking, and follows a similar format: starting with the
principles; then detailing peer-reviewed case studies for
earthquakes, radioactivity, and climate change; and concluding with
a judgment of the general risks involved. Shale Gas and Fracking:
The Science Behind the Controversy provides readers with the
unbiased information they need to make informed decisions on the
controversial issue of fracking.
This book focuses on understanding the shoreline dynamics,
nearshore processes and sediment transport around Rameswaram Island
and the cities of Dhanushkodi and Arichamunai. Rameswaram Island is
located between the Gulf of Mannar on the south and Palk Bay on the
north, between the southern tip of India and Sri Lanka, and is
unique in terms of physical, chemical and biological processes. The
Gulf of Mannar is established as a marine biodiversity conservation
area by its richness of variety and variability of marine species
such as corals, finfish, shellfish and other fishes. The island is
predominantly influenced by four seasons: northeast monsoon,
post-monsoon, summer and southwest monsoon; and the
sedimentological and hydrodynamic conditions significantly change
seasonally, resulting in the island's responding in a different
manner with each season. It also explains the physical forces and
their impacts around these areas. Rameswaram Island has existed
naturally for a long period of time even under the influence of
different water masses of the Gulf of Mannar and Palk Bay.
Understanding the regional natural phenomena is the only solution
to carry out the best management practices to develop coastal
constructions and modifications.

Worldwide demand for sand and gravel is increasing daily, as the
need for these materials continues to rise, for example in the
construction sector, in land filling and for transportation sector
based infrastructural projects. This results in over-extraction of
sand from channel beds, and hampers the natural renewal of
sediment, geological setup and morphological processes of the
riverine system. In India, illegal sand mining (of alluvial
channels) and gravel mining (of perennial channels) are two
anthropogenic issues that negatively affect the sustainable
drainage system. Along the Kangsabati River in India, the
consequences of sand mining are very serious. The construction of
Mukutmonipur Dam (1958) on the river causes huge sediment
deposition along the middle and downstream areas, these same areas
are also intensely mined for sand (instream and on the flood
plain). Geospatial models are applied in order to better understand
the state and the resilience of stream hydraulics, morphological
and river ecosystem variables during pre-mining and post-mining
stages, using micro-level datasets of the Kangsabati River. The
book also includes practicable measures to minimize the
environmental consequences of instream mining in respect to optimum
sand mining. It discusses the threshold limits of each variable in
stream hydraulics, morphological and river ecological regime, and
also discusses the most affected variables. Consequently, all
outputs will be very useful for students, researchers,
academicians, decision makers and practitioners and will facilitate
applying these techniques to create models for other river basins.
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 on Kenya s natural
environment and resources. It provides a sound scientific
introduction to this country s physical and socioeconomic setting
and its evolution through time and will appeal to a broad audience
of students in Kenya and abroad as well as those working in the
development and humanitarian sectors and to international donors
looking for a scientific compendium on Kenya s environment. Its
structure and references allow the reader to deepen his or her
knowledge of every theme touched on in the book.
Combines different aspects of physical geography, water and soil
resources and their management strategiesWritten by a blend of
international and national experts Includes specific case

Interest in the environment has never been greater and yet most of
us have little knowledge of the 4 billion years of history that
formed it. This book explains the principles of geology, geography
and geomorphology, and shows how a basic understanding of
geological timescales, plate tectonics and landforms can help you
'read' the great outdoors. This is a highly illustrated book with a
very accessible text that beautifully illuminates the landscape
around us.
