As the last quarter of 2015 begins, production data show that total red meat and poultry production, aggregated over the first three quarters of 2015, increased by less than 1 percent over the same period of 2014. In the first three quarters of 2015, beef production is about 3 percent below production in the same period last year. Cattle prices so far in 2015 have averaged almost 3 percent above prices in the same period of 2014. Production effects of disease outbreaks link the pork and poultry sectors, but in divergent directions: the pork sector continues to recover from the effects of porcine epidemic diarrhea (PEDv) outbreaks last year, with total production in the first three quarters of 2015 almost 8 percent ahead of the same period in 2014. The poultry sector is recovering from Highly Pathogenic Avian Influenza (HPAI), the effects of which has fallen so far on the turkey sector (2 percent lower production) and the egg sector (5 percent lower production). Turkey prices have averaged almost 6 percent above the same period last year; average egg prices are almost 36 percent above the same period of 2014. Broiler production is up in 2015 by 4 percent.

Agricultural systems are uniquely complex systems, given that agricultural systems are parts of natural and ecological systems. Those aspects bring in a substantial degree of uncertainty in system operation. Also, impact factors, such as weather factors, are critical in agricultural systems but these factors are uncontrollable in system management. Modern agriculture has been evolving through precision agriculture beginning in the late 1980s and biotechnological innovations in the early 2000s. Precision agriculture implements site-specific crop production management by integrating agricultural mechanization and information technology in geographic information system (GIS), global navigation satellite system (GNSS), and remote sensing. Now, precision agriculture is set to evolve into smart agriculture with advanced systematization, informatization, intelligence and automation. From precision agriculture to smart agriculture, there is a substantial amount of specific control and communication problems that have been investigated and will continue to be studied. In this book, the core ideas and methods from control problems in agricultural production systems are extracted, and a system view of agricultural production is formulated for the analysis and design of management strategies to control and optimize agricultural production systems while exploiting the intrinsic feedback information-exchanging mechanisms. On this basis, the theoretical framework of agricultural cybernetics is established to predict and control the behavior of agricultural production systems through control theory.
