Many factors will shape global food security over the next few decades, including changes in rates of human population growth, income growth and distribution, dietary preferences, disease incidence, increased demand for land and water resources for other uses (i.e. bioenergy production, carbon sequestration and urban development) and rates of improvement in agricultural productivity. This latter factor, which we define here simply as crop yield (i.e. metric tons of grain production per hectare of land), is a particular emphasis of the plant science community, as researchers and farmers seek to sustain the impressive historical gains associated with improved genetics and agronomic management of major food crops. Much of what is known about the process of technological innovation in agriculture has yet to be captured in the discussions of climate change adaptation. The development of technological solutions to minimise risks of current climate can lead to two possible outcomes: increase in agricultural productivity and insights about adaptation to future climate change. Research efforts about the role of technological change, driven by climatic constraints, are pivotal in making any assertion about the likely adaptation of agriculture to climate change.
