Climate change and migration are major concerns in the MENA region, yet the empirical evidence on the impact of climate change and extreme weather events on migration remains limited. Information is broadly lacking on how households in vulnerable areas perceive changes in the climate, how they are affected by extreme weather events, whether they benefit from community and government programs to help them cope with and adapt to a changing climate, and how these conditions influence the decision of household members to migrate, either temporarily or permanently. This introductory chapter summarizes briefly the main results of the study which relied on existing data as well as focus groups and new household surveys collected in 2011 in Algeria, Egypt, Morocco, Syria, and Yemen. The results suggest that households do perceive important changes in the climate, and that many households are being affected by extreme weather events resulting in losses in income, crops, and livestock. The coping and adaptation strategies used by households to deal with weather shocks are diverse, but also limited, with most households not able to recover from the negative impact of weather shocks. The ability of community level responses and government programs to support households is also very limited. Finally, while climate change is not today the main driver of migration flows, it does appear to contribute substantially to these flows, so that worsening climatic conditions are likely to exacerbate future migration flows.
To respond to the increasing need to feed the world's population as well as an ever greater demand for a balanced and healthy diet there is a continuing need to produce improved new cultivars or varieties of plants, particularly crop plants. The strategies used to produce these are increasingly based on our knowledge of relevant science, particularly genetics, but involves a multidisciplinary understanding that optimizes the approaches taken.

Where There is No Vetis more than just a book on first aid for animals. It aims to help people keep their animals healthy. It covers a wide range of topics that affect the health of livestock, from diarrhea to rinderpest, from helpful traditional remedies to the uses of modern medicines and vaccines. It includes advice on the care, feeding and handling of animals. By describing the signs of disease to look for, it helps readers to work out what is wrong with an animal and then tells them what to do about it. Special emphasis is placed on preventing and controlling diseases and problems. The book covers routine treatments, assisting births and dealing with emergencies and simple operations. Not only does it help readers realize what they can do for their own animals, it also helps them recognize which problems need assistance from experienced vets or skilled workers.
The book deals with cattle, buffaloes, goats, sheep, pigs, horses, donkeys and camels. It also describes some important problems of dogs, rabbits and poultry.
The book is essential for anyone who keeps animals and for people who help advise or teach others who keep animals:
· The farmer who lives far from a vet. It explains in simple words and drawings what can be done to prevent, recognize, and treat many common sicknesses.
· The teacher in a rural school. The book gives guidelines for teaching other people about animal health and will be useful in the teaching of agricultural science.
· The NGO worker or agricultural extension worker who advises farmers on how to look after animals.
· The vet assistant or other skilled worker who advises others on how to look after their animals. The book explains which medicines or treatments are most useful for specific sicknesses and warns against any which are useless or dangerous.

Man's explosive intrusion into forest ecosystems has not only
affected the present character of our forests but in a more profoundly
disturbing way has also affected the evolution of our
future forests. Not only are the trees growing today different
from those of past decades, but we have often lost the resilient
capacity of this renewable resource to respond to the changing
demands of nature and man. When whole forests are lost, the
genes are lost, and replanting the land cannot recover the potential
of any extinct genes. Even during breeding, the genetic resource
may often be so reduced that future evolution is halted. Today,
forests are being more intensively exploited and the forester has
an obligation to safeguard the future of his resource. He can constructively
direct the evolution of forests toward increased productivity
within a genetic system that is capable of cumulative
improvement and of meeting the varying and uncertain demands
of the future.
Environmental preservation, resource conservation and assuring
of food quality for the ever growing population had been the
major challenges in agriculture during the last two decades.
Growing awareness among consumers for safe and healthy food
grown in tandem with nature has triggered the growth of another
food segment across the world. Organic farming was found to be
the most viable and effective option to address all these concerns
and to address the consumers need. Although modern organic
agriculture has its roots in consumers’ desire for safe and healthy
food and has emerged from western developed economies, of
late it has also caught the attention of sustainability promoters
and has been found to address all the global concerns. Organic
farming in its modern form is not only productive enough to
meet our growing demands but is also resource conserving and
continuously contributing to the improvement of soil health
and fertility. Ardent promoters of organic farming consider that
present day organic agriculture, which is a mix of traditional
wisdom and modern science and technology, can meet emerging
demands and become the means for complete development of
rural areas, especially in the developing countries like India
where large chunk of farmers are small, with limited resources
and with limited access to water, mainly through seasonal rains.

This book provides an overview of the rapidly-developing field of quantitative genetics and genomics, and their application to plant breeding. Chapters have been developed from a symposium held in Baton Rouge, Louisiana, in March 2001. Authors include international authorities from around the world. Contents include quantitative trait loci (QTL) mapping, genomics and marker-assisted selection; tissue culture and alien introgression for crop improvement; and advances in genotype by environment interaction/stability analysis.
The horticulture sector encompasses a wide range of crops namely fruit crops,
vegetables crops, potato and tuber crops, ornamental crops, medicinal and aromatic
crops, spices and plantation crops. New introductions like mushroom, bamboo and
bee keeping (for improving the crop productivity) further expanded the scope of
horticulture. While the first few Five Year Plans assigned priority to achieving self
sufficiency in food grain production, over the years, horticulture has emerged as an
indispensable part of agriculture, offering a wide range of choices to the farmers for
crop diversification. It also provides ample opportunities for sustaining large number
of agro-industries which generate substantial employment opportunities. The
horticulture sector contributes around 28% of the GDP from about 13.08% of the
area and 37 % of the total exports of agricultural commodities.
During the previous three Plan periods, focused attention was given to horticultural
research and development which placed India as the second largest producer of
fruits and vegetables, largest producer and consumer of cashew nut, tea spices, third
largest producer of coconut, forth largest producer and consumer of rubber and sixth
largest producer of coffee in the world. Today, as a result synergy between focused
research, technological and policy initiatives, high efficiency inputs, horticulture in
India, has become a sustainable and viable venture for the small and marginal
farmers. Besides, the sector has also started attracting entrepreneurs for taking up
horticulture as a commercial venture. Therefore, there is a great scope for the
horticulture industry to grow and flourish.
