The demands for food supply, socio-economic factors, environmental and technological revolution as well as political factors; many of which are spatially specific, have been identified as tools that shaped the characteristic trends in agricultural systems evolution. It is important to know that the performance of agriculture measured (before now) in terms of food, fiber and bio-energy production is now, to a large extent, measured on a range of other social and environmental outcomes, positive and negative. However, the emerging consensus of agricultural mechanization at meeting the needs of a growing and potentially more prosperous global population mainly from the existing stock of agricultural resources has gone a long way in saving the world's ecosystems that could have been irreparably damaged. These needs therefore necessitated a study of the historic events that led to agricultural evolution, revolution, and developments that transcends the old and the new worlds to the 18th century agricultural and industrial revolutions; the 19th century innovations in tools mechanization and power developments, the 20th century complex machines and equipment design and manufacturing among others, which this book gave an explicit account of from the pre-agricultural times (over 3million years ago) through the agricultural times (10,000 years ago) into the agro-based times (19th and 20th centuries) and the emerging sustainable technologies in agricultural mechanization of the 21st century, thereby incorporating future developments.

As long as agriculture underpins the survival of humanity, safety remains a relevant issue to life security in and around the farm community for system sustainability. An understanding of the issues and values of hazard and safety in machinery operations will aid in decision-making reinforced by principles and practice. The diversity and complexity of agricultural and related machinery have become an index for increased rate of accident and injury occurrence experienced during operations and maintenance. Therefore, the study of machinery hazards, hazard sources and points in machinery and subsequent safe practices will help to eliminate, eradicate or control such hazards and provide workers with the opportunity to operate machinery more safely and develop skills in improved material and machine handling, as well as facilitate effective utilization of signal communication techniques and the attainment of relevant knowledge in accident prevention in primary production processes. One fundamental and pertinent question one should ask therefore is 'how safe is your farm?' Response to this question is salient but essential for safe-farm machinery operation (SMO) and increased productivity and reduced downtime due to accident incidences and accident compensation claims. Such measures were presented in this book as you take a journey through it.

Sustainability of agricultural production system is becoming a major concern to agricultural research and policy makers in both developed and developing countries as it represents the last step in a long evolution of the protection of natural resources and the maintenance of environmental quality. Hence, sustainable agriculture is based on approaches that address farmers' marginal interests of reduced stress and comfort, reduced soil degradation, conservation of natural resources, and provision of adequate and dependable farm income in order to reduce poverty and associated problems. To this end, a more sustainable solution is imperative to solving these problems. This 6-part book furnish scientists and students with fundamental views on scientific developments, research outcome on sustainable solutions and also offers guidance on dissemination of sustainable agricultural techniques and feasible applications to Nigeria situation as a way of wriggling out of the ever expensive, soil and environmentally degrading conventional agricultural machines and inorganic production practices.

As long as we live within environments laden with hazards, it is our responsibility to make the environment favourable by locking hazards away. Many people world over died as a result of the consequences of avoidable occupational and environmental hazards that constitute part of our workplaces. It is our responsibility therefore to provide guide for workers' safety in our workplaces, make them have a change of attitude to ensure a safe work environment. One of the greatest assets to safe-living and safe machine operation is to follow safe work procedures in order to make our workplaces safe. This book x-rays the various workplaces and associated hazards as well as provides an insight to some measures of safety while operating within them. Remember, it is important to make rules about safety; however, it is more important to ensure safety by locking dangers away.
