Public infrastructure in the context of "Public works"

Asset management is a systematic approach to the governance and realization of all value for which a group or entity is responsible. It may apply both to tangible assets (physical objects such as complex process or manufacturing plants, infrastructure, buildings or equipment) and to intangible assets (such as intellectual property, goodwill or financial assets). Asset management is a systematic process of developing, operating, maintaining, upgrading, and disposing of assets in the most cost-effective manner (including all costs, risks, and performance attributes).

Theory of asset management primarily deals with the periodic matter of improving, maintaining or in other circumstances assuring the economic and capital value of an asset over time. The term is commonly used in engineering, the business world, and public infrastructure sectors to ensure a coordinated approach to the optimization of costs, risks, service/performance, and sustainability. The term has traditionally been used in the financial sector to describe people and companies who manage investments on behalf of others. Those include, for example, investment managers who manage the assets of a pension fund.

Reichskommissariat (English: Realm Commissariat) is a German word for a type of administrative entity headed by a government official known as a Reichskommissar (English: Realm Commissioner). Although many offices existed, primarily throughout the Imperial German and Nazi periods in a number of fields (ranging from public infrastructure and spatial planning to ethnic cleansing), it is most commonly used to refer to the quasi-colonial administrative territorial entity established by Nazi Germany in several occupied countries during World War II. While officially located outside the German Reich in a legal sense, these entities were directly controlled by their supreme civil authorities (the Reichskommissars), who ruled their territories as German governors on behalf of and as representatives of Adolf Hitler.

The introduction of these territorial administrations served a number of purposes. Those established or planned to be established in Western and Northern Europe were in general envisioned as the transitional phases for the incorporation of Germanic countries outside pre-war Germany into an expanded Nazi state. Their eastern counterparts served primarily colonialist and imperialist purposes, as sources of Lebensraum for German settlement and the exploitation of natural resources.

The Raj of Sarawak, Kingdom of Sarawak or State of Sarawak, was a kingdom founded in 1841 in northwestern Borneo and was in a treaty of protection with the United Kingdom from 1888. It was formed from a series of land concessions acquired by the Englishman James Brooke from the Sultan of Brunei. Sarawak was recognised as a sovereign state by the United States in 1850, and by the United Kingdom in 1864. Since the formation of Malaysia on 16 September 1963, The Raj has been a constituent state of Malaysia as the state of Sarawak.

Following recognition, Brooke expanded the Raj's territory at the expense of Brunei. Several major rebellions occurred against his rule, causing him to be plagued by debt incurred in countering the rebellions, and the sluggish economic situation at the time. His nephew, Charles Brooke, succeeded James and normalised the situation by improving the economy, reducing government debt and establishing public infrastructure. In 1888, the Raj acquired protected state status from the British Government whilst avoiding cession.

Tree care is the application of arboricultural methods like pruning, trimming, and felling/thinning in built environments. Road verge, greenways, backyard and park woody vegetation are at the center of attention for the tree care industry. Landscape architecture and urban forestry also set high demands on professional tree care. High safety standards against the dangers of tree care have helped the industry evolve. Especially felling in space-limited environments poses significant risks: the vicinity of power or telephone lines, insufficient protective gear (against falling dead wood, chainsaw wounds, etc.) and narrow felling zones with endangered nearby buildings, parking cars, etc. The required equipment and experience usually transcends private means and is often considered too costly as a permanent part of the public infrastructure. In singular cases, traditional tools like handsaws may suffice, but large-scale tree care usually calls for heavy machinery like cranes, bucket trucks, harvesters, and woodchippers.

Road side trees are especially prone to abiotic stress by exhaust fumes, toxic road debris, soil compaction, and drought which makes them susceptible to fungal infections and various plant pests like the spotted lantern fly. When tree removal is not an option, because of road ecology considerations, the main challenge is to achieve road safety (visibility of road signs, blockage-free lanes, etc.) while maintaining tree health.
