Agriculture in the 21st century will need considerable modification
to remain both productive and sustainable. Greater production is
needed to meet the needs of our still-growing populations and to
combat hunger and poverty. Declines in soil health and the
pollution of water sources are making many of our production
systems less tenable. These adverse trends are exacerbated more and
more by the impacts of climate change. There are, fortunately,
alternative methods available for agricultural practice that can
countervail these constraints. Biological Approaches to
Regenerative Soil Systems brings together the work of both
researchers and practitioners to map out better approaches to
contemporary agriculture that draw upon both old and new knowledge.
It presents the science that underlies more biologically-driven
strategies as well as contemporary innovative experiences in
diverse parts of the world. Both accepted research and these varied
experiences encourage confidence that these approaches, not relying
primarily on the introduction of new varieties and on exogenous
inputs, can succeed. This book updates and revises a preceding
volume Biological Approaches to Sustainable Soil Systems published
by CRC Press in 2006. So much has been learned and done on this
subject in the past decade and a half that a second edition was
warranted. For instance, since the previous volume was published,
knowledge has mushroomed about plant-soil microbiomes, which are a
frequent focus in this book. Because sustainability is a broad term
and an end-state, the editors preferred to assemble expertise
regarding regenerative agriculture, which is concerned with the
means for achieving sustainability. The concept of regenerative
soil systems, entities that are more complex and multi-faceted than
‘soil’ alone, incorporates a concern with having also more
resilient agricultural systems, ones that are better able to cope
with the multiple stresses of climate change which are foreseen for
the decades ahead. The book’s chapters representing a wide range
of disciplines were contributed by 84 scientists and practitioners
from 20 countries. Although they come from persons with in-depth
knowledge of their respective fields, the chapters are written to
be accessible to readers not trained in the specialized subjects.
Taken together, the chapters provide students, researchers,
practitioners, planners, and policy makers with a comprehensive
understanding of both the science and the steps needed to
regenerate and sustain soil systems around the world for the
long-term benefit of humankind and the environment.
Addressing a topic of major importance to the maintenance of world
food supplies, this reference identifies knowledge gaps, defines
priorities, and formulates recommendations for the improvement of
the rice-wheat farming system. The book reveals new systems of rice
intensification and management and illustrates the application of
no-till and conservation farming to the rice-wheat system. With
contributions from 65 international experts, and case studies from
India, Nepal, Pakistan, and Bangladesh, Sustainable Agriculture and
the International Rice-Wheat System focuses on seeding equipment
and residue management, weed control, water and nutrient
efficiency, and integrated pest management.
Can developing countries meet the food requirements of their
growing populations without jeopardizing a natural resource base
that is already under great stress? Can increases in food
production achieved in the past two decades be sustained in the
next two decades? Can developing countries achieve freedom from
hunger and malnutrition for their entire populations? How can food
security be reconciled with environment quality in an
industrializing society? Leading authorities, from soil scientists
to economists, address these critical questions in Food Security
and Environmental Quality in the Developing World. With a focus on
India, this book reviews the state of natural resources, fertilizer
and energy needs, and the potential importance of biotechnology as
they affect all developing countries. It then addresses issues
pertaining to water quality, agricultural chemicals, and pesticide
residues on food. Part Three examines water harvesting,
post-harvest food losses, storage and processing of animal
products, and sustainability and inequality issues. The next
sections deal with poverty alleviation, microfinance, gender
equity, policy issues, and the role of the public sector. Finally,
the book considers emerging issues and priorities. Developing
countries have achieved an impressive increase in total food
production over the past two decades, but at a high cost to
environmental quality. As the populations of these countries
continue to grow, soil degradation, pollution and contamination of
natural waters, deteriorating air quality, and growing dependence
on expensive and diminishing fossil fuels become increasing
concerns. Food Security and Environmental Quality in the Developing
World takes on the crucial challenge of enhancing agricultural
production while reversing the alarming trends in soil and
environmental degradation.
"In this timely publication, Dr Rott has sourced contributions from
scientists working on cane throughout the tropics...Richly
referenced, this is both an informed and informative book that is
well written. It will appeal to both researchers and cane growers."
International Sugar Journal/Agribusiness intelligence Sugarcane is
the source of over three quarters of the world's sugar, and is
grown widely in the tropics and sub-tropics. Despite rising demand,
average yields have not increased significantly, partly because of
continued vulnerability to pests and diseases. In addition,
cultivation has been seen as damaging biodiversity and soil health
with a negative effect on both yields and the environment. This
volume summarises the wealth of research addressing these
challenges. Volume 1 reviews cultivation techniques and
sustainability issues. Part 1 summarises current best practice in
sugarcane cultivation across the value chain, from planting through
to post-harvest operations. Part 2 looks at ways of measuring the
environmental impact of sugarcane cultivation as well as ways of
supporting smallholders. With its distinguished editor and
international team of expert authors, this will be a standard
reference for sugarcane scientists, growers, government and
non-governmental agencies responsible for supporting and monitoring
the impact of sugarcane cultivation. It is accompanied by a
companion volume reviewing breeding, pest and disease management.
In order to feed their burgeoning populations, developing nations
will need to double cereal production by the year 2050. This
increase will have to come from existing land, as little potential
exists for bringing new land under cultivation -- a daunting
prospect when one realizes that increased use and significantly
higher concentrations of carbon dioxide have led to a severe
depletion of the carbon pool in the world's soils. This is
especially telling in developing countries where tropical climates
further compromise the soil's ability to recover. In Climate Change
and Global Food Security, bestselling editor Rattan Lal heads up a
team of the world's top soil scientists and ecologists to document
the history of this impending agricultural crisis and explore
possible solutions. Throughout this timely text, the authors
address six complex themes: 1. The impact of projected climate
change on soil quality, water resources, temperature regime, and
growing season duration on net primary productivity of different
biomes 2. Soil carbon dynamics under changing climate 3. The impact
of changes in carbon dioxide and ecological environments on
agronomic yields and food production in different regions of the
world 4. World food demands and supply during the 21st century 5.
Policy and economic issues related to carbon trading and enhancing
agricultural production 6. Research and development priorities for
enhancing soil carbon pool and food security This hard-hitting text
is essential reading for anyone involved with soil and crop
sciences as well as policy makers and change agents who need to
come to the forefront of this issue armed with the latest
information and viable solutions.
Traditionally, indigenous irrigation in many countries of Asia,
Africa, and Latin America has been managed quite well by water
users, who design, build, operate, and maintain often
sophisticated, but usually small-scale, systems. More recently, in
connection with large-scale development programs and
government-managed schemes, the planned introduct

The world's food supply needs to rise significantly, yet both
arable and water supplies per capita are decreasing. Not only are
modern agricultural methods beyond the reach of those suffering the
greatest food insecurity but they are also ecologically damaging,
relying upon fossil energy and chemical inputs. This volume offers
a collection of innovative and diverse approaches to agricultural
development. Documented in 12 case studies, these approaches are
reliant upon greater knowledge, skill and labour input, rather than
larger capital expenditure. They are shown to increase yield
substantially, sometimes doubling or tripling output. This volume
presents the concepts and operational means for reorienting
agricultural efforts towards these more environmentally friendly
and socially desirable approaches in the developed as well as
developing world.
