Polyploidy and hybridization for crop improvement, edited by A.S. Mason
SB106 I47 P59 2016, Parks Library Tier 1
Many of our current agricultural crops are natural or agricultural hybrids (between two or more species), or polyploids (containing more than one genome or set of chromosomes). These include potato, oats, cotton, oilseed rape, wheat, strawberries, kiwifruit, banana, seedless watermelon, triticale and many others. Polyploidy and hybridization can also be used for crop improvement: for example, to introgress disease resistance from wild species into crops, to produce seedless fruits for human consumption, or even to create entirely new crop types. Some crop genera have hundreds of years of interspecific hybridization and ploidy manipulation behind them, while in other genera use of these evolutionary processes for crop improvement is still at the theoretical stage. This book brings together stories and examples by expert researchers and breeders working in diverse crop genera, and details how polyploidy and hybridization processes have shaped our current crops, how these processes have been utilized for crop improvement in the past, and how polyploidy and interspecific hybridization can be used for crop improvement in the future.
Shared governance for sustainable working landscapes, by T.M. Gieseke
S494.5 S86 G54 2017, Parks Library Tier 1
Sustaining our agricultural landscapes is no longer just a technical, scientific or even political problem, but it has evolved into a socially complex, so-called wicked problem of conflicting social governance and economics. This creates an extreme economic obstacle where the value of ecosystem services remains low and diffuse and the transactions costs remain high and multiple.Using Uber-like business platform technology and a shared governance model, a symbiotic demand for environmental benefits is created. Enabling multi-sector transactions for environmental benefits, this platform innovation would remedy the “tragedy of the commons”; the economic nemesis to achieving landscape sustainability. In a nutshell, to sustain our agricultural landscapes a transdisciplinary approach supported by a shared governance model housed within a multi-sided platform in needed. This book introduces an assessment framework identifying governance actors, styles and ratios for socio-ecological systems. The assessment uses a new governance compass to identify the types of actors completing which tasks and identifies the styles of governance used to complete the tasks. It is aimed to anyone involved in sustainability science, agricultural policy planning, or integrated landscape design.
