Although Russia’s grain growing regions have experienced episodic droughts, the financial impact of climate change has to date been modest when measured in terms of value of production lost. As industrial agriculture continues to emit greenhouse gases, the impact of climate change will intensify, making Russia’s southern regions drier and hotter, and potentially forcing a structural shift in production northward, an event that will lead to lower yields and grain output. The sustainable sector in Russia’s agricultural system is not able to compensate for lower grain output in the south, nor is it able to feed the nation or ensure food security across the full spectrum of commodities that consumers expect. The prospect of Russia as a declining grain power impacts the dozens of nations that import Russian grain, most notably authoritarian regimes in the Middle East.

Sustainable buildings tend to maximize power and information rather than efficiency. The multidimensional concepts and tools provided by systems ecology and thermodynamics aid the understanding of building performance and sustainability as part of the global and complex thermodynamic phenomena in living systems—energy is not concentrated, but it flows, increasing the flow rate of useful energy. From such an extended macroscopic perspective, this paper addresses holistic eco-systemic criteria of building performance evaluation, focusing on emergy (spelled with an “m”) and information—the two critical indices of extensive and intensive analysis. Emergy aggregates the utmost and upstream energetic impacts, whereas information evaluates the structural pattern of the energy-flow distribution. These indices are theoretically correlated under the principles of ecological energy transformation and are often practically compatible. To clarify the definitions and appropriate scientific contexts of the new indices for environmental building studies, we review information theory, ecological theorems, and a few pioneering studies. Emergy and information have a great potential for advanced environmental building analysis, but building-scale implementation of emergy, information, and system principles remains a scientific challenge. The findings call for further research into the improvement of building-specific emergy/information data and reliable evidence of the analogy between building and open living systems.
