Background: Exponential growth in the world population coupled with increasing environmental damage underlines the need for more sustainable and environmentally-friendly approaches to agricultural practice. Many current approaches utilize chemical additives to accelerate crop growth. Newer more environmentally-friendly strategies include the use of transgenic plants and plant-growth promoting bacteria (PGPB). Unfortunately most PGPBs identified thus far fix little or no nitrogen.

Silviculture in an Uncertain World: Utilizing Multi-Aged Management Systems to Integrate Disturbance
Publication dateObjectiveSectorsAccording to this article, forest management faces an uncertain future with changing climates and disturbance regimes. Multi-aged forest management systems represent a promising approach for increasing resistance and resilience, thereby limiting major disruptions to timber production and other ecosystem services. Multi-aged stands inherently have greater resistance and resilience to disturbances because of the presence of several age classes and more potential pathways for post-disturbance management and recovery.

According to this article, a major challenge for foresters in the future will be issues related to global change. Global change expresses itself in a variety of ways, depending on regional vegetation and climate patterns, small-scale topographic differences, tree species, and stand development stages. Using silviculture as an example, the variety of steps linking global change--as a general concept--and actual management decisions are explored. The first task is to relate global change aspects to silviculturally relevant scales.
