The Conservation Reserve Program reduced available cropland in the United States by 34 million acres under the first nine signup periods (1986–1990). Among these are ten million acres with wheat base and four million acres with corn base, which could potentially produce 288 million bushels of wheat and 340 million bushels of corn per year upon contract expiration. The impacts of expiring CRP contacts on the production and prices of wheat and corn in the United States are estimated. Based on past production practices and post-CRP land-use intentions of contract holders, 48.2% of base acres enrolled in CRP will return to production. Under this scenario, wheat prices will decline by more than 7% and corn prices by more than 2% by 2000, unless ARP levels, normal flex acres percent, or target prices are changed.

A variety of plant and animal resources (waste) can be used as biofuel. The use of biofuel is less profitable than fossil fuels, so many countries introduce special subsidies to encourage their consumption. However, to obtain these subsidies, it is necessary to prove that companies, in case of purchasing imported materials, buy them in countries that support the principles of the current climate agreement. Unlike the United States, which left the Paris climate agreement, Russia has ratified it. This means that European companies have a strong economic interest in purchasing biofuel from Russia, and not from the United States. And Russian timber companies are increased in their motivation for the efficient processing of waste of their main production into a popular export product — fuel pellets and briquettes. However, many timber producers are faced with the problem of choosing a particular type of fuel that is optimally produced in specific production conditions. Keywords: wood waste, biofuel, fuel pellet, fuel briquette.

Eucalypts are being considered for biofuel production in the Lower Coastal Plain of the United States. The evolution of eucalypts in Australia has equipped some species to be successful in plantations and has also influenced their potential as invasive species. More than 200 eucalypt species have been evaluated in many countries around the world. Generally eucalypts have proved to have limited invasive potential for a number of reasons, including their poor dispersal capabilities. Two regions with climates similar to the Lower Coastal Plain of the United States are identified in Argentina and China. Frosts, particularly sudden frosts, are an important limitation for eucalypts in these regions, so existing plantations are very limited. However, invasive eucalypts do not appear to be a major problem in other regions of either country. The use of carefully selected frost-tolerant species and the development of genetically modified eucalypts may now open up more frost-affected areas for eucalypt plantations. Some control actions may be necessary and research needs are outlined, but it is concluded that experience in other regions around the world suggests that eucalypts are likely to be a relatively low risk as invasive species in the Lower Coastal Plain.
