Definition of the Subject

Atmospheric concentration of carbon dioxide (CO2) can be stabilized, if not reduced, by reducing anthropogenic emissions, sequestering emissions, or both. Emission reduction implies identifying and using no-carbon (C) or low-C energy sources such as alternatives to fossil fuel including wind, solar, hydro, geo-thermal, biofuels, etc. Reductions in gaseous emissions can also be achieved by enhancing the energy use efficiency. In agronomic systems, involving practices to raise crops and livestock, enhancing energy efficiency implies a range of practices which increase agricultural productivity per unit input of energy-based resources (i.e., fertilizers, pesticides, irrigation). Another strategy is elimination or reduction in frequency and intensity of tillage operations and converting plow-based tillage to no-till farming or conservation agriculture. Use of solar and wind energy for grain drying, water pumping, and heating buildings can also reduce...
