Forestry and energy resources
Forestry and energy resources encompass the management and utilization of forest ecosystems for various purposes, primarily focusing on timber production and renewable energy. Historically, forestry practices began in ancient China and evolved significantly in Europe, particularly during the Middle Ages, with countries like Germany and Japan leading systematic forest management initiatives. In North America, the establishment of forestry schools and the influence of notable figures like Carl Schenck and Gifford Pinchot helped shape modern forestry practices.
As populations grew, the demand for wood as a primary energy source and construction material led to unsustainable practices such as clear-cutting, prompting a shift towards more responsible forest management and conservation efforts in the late 19th century. Today, modern forestry integrates advanced technologies like geographic information systems and remote sensing to monitor forest health and yields. The field emphasizes sustainable forestry, balancing commercial interests with environmental preservation.
Forests also play a vital role in global commerce, providing materials for a wide range of products beyond timber, including pharmaceuticals and household items. The ongoing debate between conservation and economic development continues to shape forestry policies worldwide, highlighting the complexities of resource management in diverse cultural and economic contexts.
Forestry and energy resources
Billions of people, industrialists, and the economies of many nations rely on forests, which covered approximately 31 percent of the world’s landmass in 2020. The practice of forestry can ensure that there will be sustainable forests to support all living things with timber and wood products, energy resources, animal ranges, wildlife habitats, recreational opportunities, water resources, oxygen, and climate control.
Background
Forestry, considered both a science and an art, has its origins in China, while the Western world formalized the practice of forestry during the Middle Ages. By the sixteenth century, Germany and Japan were leaders in developing systematic forest management, and German foresters established many of the earliest forestry schools in the eighteenth and nineteenth centuries. Royalty often promoted forest management through mapping, harvesting, and reforestation. An example of such early forestry practices was Great Britain’s Broad Arrow Policy of 1691, which required reservation for the navy of all trees on public lands with a diameter of 60 centimeters or greater. These trees were used in large part for building ship masts—one of the significant commercial enterprises that made use of forest products in the seventeenth century.
The German influence was felt in North America by 1898 when German Carl Schenck established one of the first American schools of forestry in North Carolina. The New York State College of Forestry was also established at Cornell University in the same year. Schenck, who initially came to the United States to replace Gifford Pinchot in managing the forests of the Biltmore Estate in Asheville, North Carolina, utilized many of the German forestry methods in his education program. Pinchot, who was trained in France, was appointed by President William McKinley as the head of what became known as the United States Forest Service.
The Beginnings of Forestry
Initially, forestry involved finding ways to cultivate trees and plant materials quickly because of the depletion of wood products caused by war but also necessitated by the spread of settlements throughout the world. People used wood not only for the construction of buildings and fences but also as the main source of energy. Thus, as the population increased, the demand for wood products increased. The settlers in the New World began shipping substantial amounts of logs and lumber to the Old World, where many forests had already been depleted, often as a result of practices such as clear-cutting—the cutting of all trees in a stand with little concern for underlying plants, soil, and water resources.
As the population in the United States spread in the eighteenth and nineteenth centuries from New England south through the Appalachian forests and west to the forests surrounding the Great Lakes, early settlers practiced little forest management or conservation. Most of the settlers believed there was an endless supply of trees; not until the second half of the nineteenth century did influential politicians and authors begin to advocate for forest management and conservation. However, the United States did little to manage its forests until after many trees had been clear-cut for commercial purposes, including building railroads, and soil had been degraded through erosion.
The scientific methods employed in early forestry involved managing and improving existing forests through cutting, pruning, and thinning of forests and controlling erosion, diseases, and pests. To foster forest continuity, loggers modified their previous “cut out and get out” approach to logging and also applied science in order to protect the soil, water, and young trees in areas where timber harvesting was taking place. Many of these early scientific methods are still practiced. In addition, during the nineteenth and twentieth centuries, many nations began to adopt laws and regulations to conserve forests, protect watersheds, and establish forest reserves. In many cases, these laws were a reaction to the commercial slash-and-burn practices of the past and the technologies being employed by the logging and paper industries.
As the nineteenth century began, Pinchot philosophized that forests could be used wisely while also being preserved for the enjoyment of future generations. This multiple-use philosophy, that there can be a balance between economic and environmental factors to meet both present and future needs, is known as sustainable forestry. The debate, however, continues in modern forestry—should forests be preserved or managed for commercial timber production?
Modern Forestry Practices
Modern forestry not only employs the early scientific methods and management practices but also utilizes many new mechanized and science-based techniques. Today’s foresters use tools such as portable computers to maintain and organize forest inventory databases and to generate financial and harvest-yield models. Forest scientists link computer mapping technologies with satellite resources such as geographic information systems that allow remote sensing. Combining mapping and sensing data allows evaluation of forests, such as insect damage, forest erosion, and potential harvest yields throughout the globe. Global Positioning Systems are also important in pinpointing exact locations of forest resources that may have been identified through aerial photography or remote-sensing technologies.
Today’s forest management also involves specialization. Silviculture is the main specialty that concerns management of forests and their surroundings to establish healthy tree populations and plant materials for commercial harvesting. Silviculturalists develop forest management plans in order to ensure healthy and profitable yields, while recognizing that forests are in constant states of change, which is known as succession. In addition, genetic engineers are conducting global research to improve species that can withstand pests, diseases, and drought in specific geographic areas. Controlled or prescribed forest burning to reduce the amount of fuel available for fires, soil and watershed management to ensure that soils are adequate to support a forest and to prevent soil erosion, protection of forest ecosystems and enhancement, water quality management and pollution control, pest and disease control, and control by ensuring sufficient plant materials to create a sink for atmospheric carbon dioxide and oxygen restoration through photosynthesis are all prominent features of modern-day forestry practice and education.
The commercial enterprise of plantation forestry, much like single-crop farming, involves establishing monocultures or single varieties of trees and plant materials usually started from seeds or seedlings. Christmas tree farms and nurseries are examples of plantation forestry. Urban forestry is practiced in highly populated areas where urban living environments are enhanced through the creation of green spaces and the planting of shade tree species and other plant materials appropriate for a geographic location. Another specialty branch of forestry is tropical forestry, which takes place in equatorial forests and involves the harvesting of woods popular in furniture manufacturing, such as mahogany and teak.
Commerce vs. Preservation
Forests have substantial commercial value not only for wood and paper products such as plywood and as a renewable energy source but also for many manufactured products that are derived from trees and plant materials. Many of these manufactured products begin with a wood source that is turned into a useful product through the application of chemicals. These products include rayon, cellophane, adhesives, photo film, paints, household cleaners, baby food, ice cream, cosmetics, and food flavorings. Many pharmaceutical products also come from forest sources. Economics is important in forestry, and foresters must have an understanding of how to ensure that forest products will have sufficient quantity and quality to maintain a profitable business.
Global forestry initiatives have taken place for many years. The World Forestry Congress has met almost every six years since 1926, and the 2009 meeting in Buenos Aires, Argentina, concerned ways to achieve a balance between preserving tropical rain forests and allowing for development. The 2015 Congress, held in Durban, South Africa, investigated the role of forests in a sustainable future and climate change, while the 2022 meeting in Seoul, Republic of Korea, discussed a green future through forestry. At the 2022 meeting, the Food and Agriculture Organization of the United Nations released its 2022 State of the Forests Report. Moreover, since the 1980s, many international entities, including the United Nations, the World Bank, and the European Forest Institute, have begun to formulate and implement global conservation-oriented forestry strategies and initiatives.
However, not all world leaders agree that conservation is the best policy, as national development varies globally from hunter-gatherer societies to industrialized nations that place an emphasis on the commercial value of forest products. Many developing nations believe in the maximum use of their forests to fuel their development in the same manner that industrialized nations overused their forests to enhance their economies. Although overuse of forests and lack of forest management in one area of the globe will impact other areas, the many international agencies trying to resolve the global forestry debate between for economic development and are not likely to come to an easy resolution.
