Book Description
This book presents a compilation of the latest findings from reputed researchers around the globe, covering in detail climate change and its effects on sheep production. In the current global climate change scenario, information related to its impact on livestock agriculture is lacking. The negative impacts of climate change are already being felt by all livestock species. Further, the mitigation and amelioration strategies that are applicable for one species may not hold true for another. As such, concerted research efforts are needed to identify species-specific strategies for mitigation and adaptation. With that goal in mind, this book is the first of its kind to gather comprehensive information pertaining to the impact of climate change on various aspects of sheep production. It also sheds light on the role of sheep with regard to the global greenhouse gas pool. The book highlights the status quo of sheep production from climate change perspectives and projects the significance of adapting future sheep production to the challenges posed by climate change. It addresses in detail the various adaptations, methane mitigation and amelioration strategies needed to sustain sheep production in the future. In addition, the book presents development plans and policies that will allow the sheep industry to cope with current climate changes and strategies that will lessen future impacts. Bringing together essential information prepared by world-class researchers hailing from different agro-ecological zones, this book offers a unique resource for all researchers, teachers and students associated with sustaining the sheep production in the face of global change.

Book Description
Summary In Israel, more than half of the national sheep flock is kept by Bedouin in the Negev desert. Extensive production systems co-exist besides semi-intensive systems with varying economic success. There is a constant regional demand for sheep meat, but the local supply is not able to cover it. The wide gap between the performance potential of the commonly used and environmentally adapted local Awassi and improved sheep breeds suggests an increase in economic efficiency by intensification of breeding. The choice of a suitable breed for a specific system is seen as key factor for the farm success and requires the knowledge of the animals’ adaptation. Information on the performance of Bedouin sheep flocks under the given harsh production conditions are, however, missing. The purpose of the study was thus a characterization of current production systems, the assessment of the aggregated performance of the different Awassi lines kept in those systems and the impact of socio-economic and production factors on the efficiency of Bedouin sheep production. Also breeding objectives of Bedouin sheep farmers were investigated. The role of new breeding technologies in the ongoing process of intensification of sheep farming systems was analyzed and discussed. Data collection was step-wise with repeated field surveys from January 2007 till March 2009, lasting 6 months altogether. In a first diagnostic survey 30 Bedouin households in the Negev desert, located in two different climatic zones, arid and semi-arid, and keeping a minimum flock size of 50 animals, were visited. Households were grouped into 4 tribe groups according to location and ethnical background. In a second step, 21 households of the previous sample were visited again and grouped according to the breed composition of their flocks and by their use of hormonal synchronization and/or artificial insemination. Semi-structured interviews and participative observation yielded information about the socio-economic situation of the household, function of flocks, the livestock husbandry, sheep management and production. Sheep market surveys, key person interviews and secondary data were used for verification of data. Detailed information on sheep was obtained through on-farm performance recording run in 16 sheep farms, including a total of 2420 breeding ewes. Sheep of different Improved Awassi lines were present in those experimental flocks, including the Afec Awassi, carrying the Booroola gene (BB/B+), which has a major impact on prolificacy, and the Assaf breed. In a last step, 56 sheep farmers from different parts of the Negev were asked about their selection criteria for replacement. Trait preferences were derived by a consecutive ranking technique. The data analysis incorporated descriptive statistics, general linear models and non-parametric tests performed with SAS 9.1 and SAS 9.2 software. The diagnostic survey revealed that functions of sheep flocks differed significantly between tribes: in the semi-arid area with a main focus on generating income, and in tribes of the arid zone with a higher importance of subsistence related and social purposes. The primary purpose was meat production. The dual purpose of meat and milk was still found in 57% of the farms, yet only 13% of the farms were selling milk products. The missing market access was the main reason for a strong decline in the use of milk, wool and manure during the last decade. Lamb meat, providing the main output of all farms, ranged from 13 to 58 kg of marketable live weight per ewe and year (LME). Classified according to their LME, 30% of the investigated farms followed an extensive, 47% a semi-extensive and 23% a semi-intensive management. Significant differences in meat output were found for the factors tribe group, breed composition of flocks and selling age of lambs. The gross margin per ewe and year varied between -27 € and 54 € and the net benefit per flock and year (NB) between -7,020 € and 20,993 €. Both economic parameters were positively related to the meat output. Negative NB’s were realized by 43% of the farms, belonging foremost to traditional Bedouin tribes, oriented towards subsistence and living in remote areas. Only 27% of economically successful farms generated an income comparable to that of a part-time off-farm job. These farmers regularly used veterinary services to introduce improved breeds and modern breeding technology. Their good market access facilitated a strong market-oriented production, integrating lamb fattening, which had the highest impact on the production success. During the two years of research a severe drought occurred in the study region, causing a decline in LME, due to lower lambing rates and higher mortalities. To adapt to changing conditions, farms keeping the pure local Awassi breed reduced their flock sizes stronger than farms keeping also crossbreds. Consequently, the LME and the NB decreased stronger in flocks of pure local Awassi, compared to flocks with crossbreds. The decline in the NB was 14 times lower in flocks with use of hormonal synchronization and/or artificial insemination than in flocks with the local breed kept under traditional management. The lowest decline in the NB and the benefit cost ratio (BCR) were found in flocks with more than 50% crossbreds. Yet, a high variation in performance among flocks with different degrees of crossbreeding was detected. Data analysis of flocks with permanent performance recording revealed that prolificacy was significantly affected by breed, besides farm and parity. Afec Awassi (B+) ewes had a significantly (p

Book Description
Agriculture continues to be an important sector fuelling economic growth. Rapidly changing climate is already affecting the production of food and feed, industrial crops, livestock, and seafood. In developing countries like India, agriculture and allied sectors contribute significantly to the gross domestic product. Therefore, evolving strategies to sustain a stable growth of the farming sector is essential for feeding a growing population and poverty alleviation in the face of global climate change. It is crucial to carry out a comprehensive analysis of different aspects of climate change to effectively combat its negative impacts on food production systems and landscapes and reap its potential benefits in agricultural production. Research findings and recommendations on topics as diverse as climate change impacts, genetic enhancement of crops, options for adaptation to climate change, opportunities and challenges for sustainable food production systems have been compiled in this volume. Capacity building for climate resilient agriculture and agriculture policy and planning is equally important to face future challenges. This book makes a compelling effort to address these major issues arising from climate change from an Indian perspective. The important and often conflicting issues in climate change impacts, adaptations and mitigations strategies are brought in to focus and a critical summary of the state-of-art in climate smart agriculture is presented for teachers, researchers and policy makers engaged with climate change and agriculture in the tropical arid and semi-arid regions of Asia and Africa.

Book Description
The increasing world population is already causing intensive pressure on the most productive areas of the earth's surface. Hopes of improved living standards, if realised, will increase the pressure still further. The need to make better use of less productive areas thus becomes an urgent priority for human endeavour. In this respect, the arid and semi-arid regions of the world, occupying about 11,000 million acres or 4,500 million hectares, roughly one third of the tota11and surface, pose a constant challenge to man's technological skill. Though the possibilities of economic use of the real deserts are inherently limited, there remain vast areas with less extreme conditions where sustained research is capable of yielding substantial gains in pro ductivity. The problem is so large that it can be solved only by the coordinated efforts of workers in many countries and many disciplines. Forestry has a special part to play, not only for its potential value for wood production but still more for the beneficial effects of shelter from desiccating winds which so commonly accompany arid conditions. Mr. KA UL is to be congratulated on his initiative to pool the results of research on afforestation in arid zones in many parts of the world, and to present them in a single volume in the form of separate monographs.
