Over the past decade, our understanding of plant adaptation to environmental
stress, including both constitutive and inducible determinants, has grown con-
siderably. This book focuses on stress caused by the inanimate components of
the environment associated with climatic, edaphic and physiographic factors
that substantially limit plant growth and survival. Categorically these are abiotic
stresses, which include drought, salinity, non-optimal temperatures and poor
In 1992, the first United Nations Conference on Sustainable
Development, popularly known as the Rio Earth Summit, was convened
in Rio de Janeiro, Brazil to address the state of the environment and
sustainable development. The Earth Summit yielded several important
agreements including “Agenda 21”, a plan of action adopted by over
178 governments to address human impacts on the environment at
local, national and global levels, and key treaties on climate change,
desertification and biodiversity.
In this significant year for the environment and sustainable
development, the world leaders will once again meet at the
United Nations Conference on Sustainable Development
20 years after the historic Earth Summit in Rio de Janeiro,
Dubbed Rio+20, one of the main themes of this Summit is ‘a
green economy in the context of sustainable development
and poverty eradication’.
Embodying this concept, the World Environment Day logo
reflects the Green Economy through several elements
that are included in the image.
The built environment embraces a wide range of concepts, from the design and integrity of housing, to
land-use and urban planning. A high quality environment is essential for children to achieve optimal health and
development. Building and land-use policies, including the quality and design of a child’s physical environment,
can cause or prevent illness, disability and injury, and degrade or preserve natural resources.
Abiotic stresses are serious threats to agriculture and the environment which have been exa‐
cerbated in the current century by global warming and industrialization. According to FAO
statistics, more than 800 million hectares of land throughout the world are currently salt-af‐
fected, including both saline and sodic soils equating to more than 6% of the world’s total
land area. Continuing salinization of arable land is expected to have overwhelming global
impact, resulting in a 30% loss of agricultural land over the next 25 years and up to 50% loss
Understand the role of solar photons as an energy source for chemical reactions in the environment. • Describe, in general, the dynamics of excited states in producing products and photo-sensitized reactants. • Understand the major abiotic chemical reaction pathways in the environment.
The Council Directive 85/337/EEC of 27 June 1985 on the assessment of the effects of certain public
and private projects on the environment
, as amended, known as the "EIA" (environmental impact
assessment) Directive, requires that an environmental assessment to be carried out by the competent
national authority for certain projects which are likely to have significant effects on the environment
by virtue, inter alia, of their nature, size or location, before development consent is given. The projects
may be proposed by a public or private person.
While most consumers still base their travel decisions largely on price, value for money,
service and availability, more and more people are taking environmental factors into
The railway community is therefore working hard to provide customers with comprehensive
information on climate change, air pollution and the ‘external costs’ of transport.
New internet-based tools, such as EcoPassenger and EcoTransIT (see Figure 6), are
making a range of data available to customers.
We believe that it is interesting to study the system and software architecture of
environments which integrate the evolving ideas of computational grids, distributed objects,
web services, peer-to-peer networks and message oriented middleware. Such peer-to-peer (P2P)
Grids should seamlessly integrate users to themselves and to resources which are also linked
to each other. We can abstract such environments as a distributed system of “clients” which
consist either of “users” or “resources” or proxies thereto.
The Abiotic Environment
The development and reproduction of insects are greatly inﬂuenced by a variety of abiotic factors. These factors may exert their effects on insects either directly or indirectly (through their effects on other organisms) and in the short- or long-term.
Carbon offsets are an innovative tool for allowing companies and individuals to reduce
greenhouse gas emissions beyond what they can easily achieve on their own. In the past
two years, interest in carbon offsets has grown dramatically as companies and concerned
consumers have sought ways to help mitigate climate change. However, the global
market for voluntary carbon offsets is currently unregulated, which has led to growing
concerns about whether buyers are really getting what they are paying for.
THE ECOSYSTEM LEVEL OF ORGANIZATION INTEGRATES species interactions and community structure with their responses to, and effects on, the abiotic environment. Interactions among organisms are the mechanisms governing energy and nutrient ﬂuxes through ecosystems.
Notwithstanding these developments in the area of governance, a recent Summit of the Organ Troika5 on Politics, Defense and Security of the South Africa Development Corporation (SADC) held at the end of March 2011 in Zambia, noted that the implementation of the GPA has been slow. The Summit was not satisfied with the polarization of the political environment characterized by the resurgence of violence, arrests and intimidation in the country.
The basic physics of sound propagation are simple, but the interaction of
sound pressure waves with complex shapes and multi-layer constructions with
openings, as you find in buildings, is more challenging. Controlling noise, both
from the internal and external environment and from the internal mechanical
and electrical services in buildings, is essential to create environments that
promote aural communication and comfortable working conditions.
While the ECB’s policy response has, to a signiﬁ cant extent, sheltered the non-ﬁ nancial private
sector from the sovereign debt crisis, and has avoided major disruptions in the ﬁ nancing of the
economy, the ﬁ nancing environment of both banks and the non-ﬁ nancial private sector of countries
affected by the sovereign debt crisis remains challenging.
The purpose of Pollution Probe’s Mercury Primer is to provide
an overview of the presence and effects of mercury in the
environment and its impacts on human health. The primer iden-
tifies where mercury is being used and released, the risks asso-
ciated with exposure to mercury, and ways to help prevent
mercury pollution. The primer also describes what governments,
businesses and individuals are doing to eliminate the use of
mercury and prevent its release to the environment.
Pollution Probe has done extensive work on mercury in the envi-
ronment for nearly a decade.
The International Institute for Sustainable Development contributes
to sustainable development by advancing policy recommendations
on international trade and investment, economic policy, climate
change and energy, measurement and assessment, and sustainable
natural resources management. Through the Internet, we report on
international negotiations and share knowledge gained through
collaborative projects with global partners, resulting in more rigorous
research, capacity building in developing countries and better
dialogue between North and South.
Addressing the options for domestic sustainable agriculture policies in developing countries, it is
generally observed that the world’s agriculture trade system is progressively moving towards an
open-market system, a process which is desirable from both a trade as well as a sustainable
development point of view.
The Internet’s rapid and profound entry into our lives quite understandably makes
people wonder how, both individually and collectively, we have been affected by it.
When major shifts in technology use occur, utopian and dystopian views of their
impact on society often abound, reflecting their disruptiveness and people’s concerns.
Given its complex uses, the Internet, both as a technology and as an environment,
has had both beneficial and deleterious effects. Above all, though, it has had
