10. Forestry

 Forestry:

Definition:

    The forestry profession includes the science and practice of establishing, managing, using, and conserving forests, trees, and related resources sustainably to fulfill desired goals, needs, and values.

Ancient history:

At least 750,000 years ago, Homo erectus was thought to have used wood for fire. The Kalambo Falls site in Tanzania contains the earliest indication of the use of timber for building, which dates to about 60,000 years ago. Scattered trees along riverbanks were used just like they are today: for fuel, construction, and handles for tools. These early structured towns were situated along streams that flowed across the dry regions of India, Pakistan, Egypt, and Mesopotamia. The Hebrew Bible's authors frequently discuss the use of wood. Images of the wooden plow and other wooden instruments being used to prepare the soil for sowing can be seen in Egyptian tombs. Wooden boats were constructed by carpenters and shipbuilders as early as 2700 BCE.

The Romans were very interested in trees and brought tree seedlings from all over the Mediterranean and Germany, creating groves that were similar to those in Carthage, Lebanon, and other places. When the Roman Empire fell, conservation efforts in the Mediterranean region came to an end, and unrestricted sheep and goat grazing, fires, and cutting, which led to the devastation of the forests, returned. In turn, this led to significant soil erosion, the silting of streams and harbors, and the transformation of the forest into the maquis, a scrubby brush cover.

The modern development in the field of Forestry:

Formal education in forestry began about 1825 when private forestry schools were established. These were the outgrowth of the old master schools such as Cotta Master School, which developed into the forestry college at Tharandt—one of the leading forestry schools in Germany. The National School of Forestry was established in Nancy, France, in 1825.

German foresters had such a strong reputation in the 19th century that they were employed throughout the majority of continental European nations. Early American foresters received their education in European institutions, including the famed conservationist Gifford Pinchot. The philosophy of responsible control, however, had to struggle against timber traders looking for rapid riches. In China, although woods originally covered over 30% of the country's area, decades of overlogging, overgrazing, and fires have brought this proportion to a low of only about 7%. China has made significant efforts to improve land usage, including the building of reservoirs and a massive program of forest planting that expanded wooded areas to 20% by 2015.

Occurrence and distribution:

Closed forests of broad-leaved and coniferous species and open forests or savannas encompass around 4,000,000,000 hectares or about one-third of the world's total land area. Because different tree species have different traits, local factors largely affect the type and distribution of forests around the world. There is an odd alliance of trees and other vegetation that is best suited to compete with other plants for that site for each combination of temperature, rainfall, and soil. With forest along streams and scatted single trees or tiny groves, the open forest is typically a tropical grassland that has been disturbed by fire. Closed thorn forests frequently surround savannahs.

In particular, in heavily populated areas, trees outside of areas designated as forestland, such as those in windbreaks, along rights-of-way, or around farm fields, are valuable resources. For instance, farmers in Rwanda maintain woodlots and pastures with trees on about 20% of the country's farmland. The aggregate area of the nation's natural forests, state plantations, and municipal plantations is greater than these dispersed tree areas. Over 90% of the farms in Kenya's Kakamega District have scattered trees that are kept trimmed for fuelwood and animal fodder. Even in France, where wood for fuel is not commonly used, trees outside of forests cover over 883,000 hectares.

Importance of Forestry:

1. It is bringing back forests:

Forests used to be cut down and left untended. Currently, 1.7 billion seedlings are planted worldwide on average each year. This translates to six saplings being planted for each tree that is harvested.

2. Maintain water quality:

Watersheds are managed carefully by foresters. These are the places where we get our drinking water, as well as riparian zones, which are the lands that border lakes, rivers, and streams. Foresters in these places place a high priority on protecting the purity of the water. Forests contribute to the natural processes that clean water so that it is safe for us to drink. These processes involve the trees, soil, and microorganisms. The soils that are essential for water retention, filtration, and quality are protected and nurtured by forest cover.

3. Remove air pollution:

A mature tree can take in roughly 13 pounds of carbon dioxide annually. This indicates that a forest removes 1.47 tonnes of carbon dioxide for every tonne of wood it produces.

4. Helps wildlife:

Different methods are used by foresters to help wildlife. For instance, thinning and harvesting foster the development of numerous food sources.

5. Good for soil maintenance:

For the growth and management of forests, forestry professionals and managers of natural resources rely on soils. The ability of foresters to understand soil qualities, match species with soils, and prescribe practices that not only promote forest growth but also increase and protect soil productivity and minimize soil erosion are all essential to successfully growing forests and producing forest products.
