Land Management
Land management is the process of managing the land use, use and development of land resources. Those resources are used for a variety of purposes for example agriculture, forestry, water resource management, Human settlement, human settlements and tourism. One aim of land management is to prevent or reverse land degradation. Another aim is to ensure water security by increasing soil moisture availability, decreasing surface runoff, and decreasing soil erosion.

Land Use
Land use is an umbrella term to describe what happens on a parcel of land. It concerns the benefits derived from using the land, and also the land management actions that humans carry out there. The following categories are used for land use: forest land, cropland ( agricultural land), grassland, wetlands, settlements and other lands. The way humans use land, and how land use is changing, has many impacts on the environment. Effects of land use choices and changes by humans include, for example, urban sprawl, soil erosion, soil degradation, land degradation and desertification. Land use and land management practices have a major impact on natural resources including water, soil, nutrients, plants and animals. ''Land use change'' is "the change from one land-use category to another". Land-use change, together with use of fossil fuels, are the major anthropogenic sources of carbon dioxide, a dominant greenhouse gas. Human activity is the most significant cause of land c ...

Human Needs
A need is a deficiency at a point of time and in a given context. Needs are distinguished from wants. In the case of a need, a deficiency causes a clear adverse outcome: a dysfunction or death. In other words, a need is something required for a safe, stable and healthy life (e.g. air, water, food, land, shelter) while a want is a desire, wish or aspiration. When needs or wants are backed by purchasing power, they have the potential to become economic demands. Basic needs such as air, water, food and protection from environmental dangers are necessary for an organism to live. In addition to basic needs, humans also have needs of a social or societal nature such as the human need for purpose, to socialize, to belong to a family or community or other group. Needs can be objective and physical, such as the need for food, or psychical and subjective, such as the need for self-esteem. Understanding both kinds of "unmet needs" is improved by considering the social context of their no ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Agricultural Land
Agricultural land is typically land ''devoted to'' agriculture, the systematic and controlled use of other organism, forms of lifeparticularly the rearing of livestock and production of cropsto produce food for humans. It is generally synonymous with both farmland or cropland, as well as pasture or rangeland. The United Nations Food and Agriculture Organization (FAO) and others following its definitions, however, also use ''agricultural land'' or as a term of art, where it means the collection of: * ''arable land'' (also known as ''cropland''): here redefined to refer to land producing crops requiring annual replanting or fallowland or pasture used for such crops within any five-year period * ''permanent cropland'': land producing crops which do not require annual replanting * ''permanent pastures'': natural or artificial grasslands and shrublands able to be used for grazing livestock This sense of "agricultural land" thus includes a great deal of land not devoted to agricultura ...

Forest Land
Forest cover is the amount of trees that covers a particular area of land. It may be measured as relative (in percent) or absolute (in square kilometres/square miles). Nearly a third of the world's land surface is covered with forest, with closed-canopy forest accounting for 4 - 5 billion hectares of land. Forests provide many ecosystem services that humans and animals cannot survive without, but anthropogenic actions and climate change are threatening global forest cover in potentially irreversible ways. Global patterns Forest cover by the numbers According to the FAO's Global Forest Resources Assessment 2020, the world has a total forest area of 4.06 billion hectares (10.0 billion acres), which is 31% of the total land area. More than one-third of the world's forest cover is primary forest: naturally regenerated forests with native species and no visible indication of human activity. More than half (54%) of the world's forests are found in only five countries (Brazil, Canada, ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Clearcutting
Clearcutting, clearfelling or clearcut logging is a forestry/logging practice in which most or all trees in an area are uniformly cut down. Along with Shelterwood cutting, shelterwood and Seed tree, seed tree harvests, it is used by foresters to create certain types of forest ecosystems and to promote select species that require an abundance of sunlight or grow in large, even-age stand level modelling, stands. Clearcutting is a forestry practice that mimics the stand initiation stage of forest succession after a natural disturbance such as Wildfire, stand replacing fire or Windthrow, wind-throw, and is successful for regeneration of fast growing, Douglas fir, sun tolerant tree species and wildlife species that readily regenerate in post-stand replacing sites. Logging companies and forest-worker unions in some countries support the practice for scientific, safety and economic reasons, while detractors consider it a form of deforestation that habitat destruction, destroys natural h ...

Harvesting
Harvesting is the process of collecting plants, animals, or fish (as well as fungi) as food, especially the process of gathering mature crops, and "the harvest" also refers to the collected crops. Reaping is the cutting of grain or pulses for harvest, typically using a scythe, sickle, or reaper. On smaller farms with minimal mechanization, harvesting is the most labor-intensive activity of the growing season. On large mechanized farms, harvesting uses farm machinery, such as the combine harvester. Automation has increased the efficiency of both the seeding and harvesting processes. Specialized harvesting equipment, using conveyor belts for gentle gripping and mass transport, replaces the manual task of removing each seedling by hand. The term "harvesting" in general usage may include immediate postharvest handling, including cleaning, sorting, packing, and cooling. The completion of harvesting marks the end of the growing season, or the growing cycle for a particular c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Weeding
Weed control is a type of pest control, which attempts to stop or reduce growth of weeds, especially noxious weeds, with the aim of reducing their competition with desired flora and fauna including domesticated plants and livestock, and in natural settings preventing non native species competing with native species. Weed control is important in agriculture. Methods include hand cultivation with hoes, powered cultivation with cultivators, smothering with mulch, lethal wilting with high heat, burning, and chemical control with herbicides (weed killers). Need for control Weeds compete with productive crops or pasture. They can be poisonous, distasteful, produce burrs, thorns, or otherwise interfere with the use and management of desirable plants by contaminating harvests or interfering with livestock. Weeds compete with crops for space, nutrients, water and light. Smaller, slower growing seedlings are more susceptible than those that are larger and more vigorous. Onions are ...

Fertilizer
A fertilizer or fertiliser is any material of natural or synthetic origin that is applied to soil or to plant tissues to supply plant nutrients. Fertilizers may be distinct from liming materials or other non-nutrient soil amendments. Many sources of fertilizer exist, both natural and industrially produced. For most modern agricultural practices, fertilization focuses on three main macro nutrients: nitrogen (N), phosphorus (P), and potassium (K) with occasional addition of supplements like rock flour for micronutrients. Farmers apply these fertilizers in a variety of ways: through dry or pelletized or liquid application processes, using large agricultural equipment, or hand-tool methods. Historically, fertilization came from natural or organic sources: compost, animal manure, human manure, harvested minerals, crop rotations, and byproducts of human-nature industries (e.g. fish processing waste, or bloodmeal from animal slaughter). However, starting in the 19th cen ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sowing
Sowing is the process of planting seeds. An area that has had seeds planted in it will be described as a sowed or sown area. Plants which are usually sown Among the major field crops, oats, wheat, and rye are sown, grasses and legumes are seeded and maize and soybeans are planted. In planting, wider rows (generally 75 cm (30 in) or more) are used, and the intent is to have precise; even spacing between individual seeds in the row, various mechanisms have been devised to count out individual seeds at exact intervals. Depth of sowing In sowing, little if any soil is placed over the seeds, as seeds can be generally sown into the soil by maintaining a planting depth of about 2-3 times the size of the seed. Sowing types and patterns For hand sowing, several sowing types exist; these include: * Flat sowing * Ridge sowing * Wide bed sowing Several patterns for sowing may be used together with these types; these include: * Rows that are indented at the even rows (so that the ...

IPCC Sixth Assessment Report
The Sixth Assessment Report (AR6) of the United Nations (UN) Intergovernmental Panel on Climate Change (IPCC) is the sixth in a series of reports which assess the available scientific information on climate change. Three Working Groups (WGI, II, and III) covered the following topics: The Physical Science Basis (WGI); Impacts, Adaptation and Vulnerability (WGII); Mitigation of Climate Change (WGIII). Of these, the first study was published in 2021, the second report February 2022, and the third in April 2022. The final synthesis report was finished in March 2023. It includes a summary for policymakers and was the basis for the 2023 United Nations Climate Change Conference (COP28) in Dubai. The first of the three working groups published its report on 9 August 2021, ''Climate Change 2021: The Physical Science Basis''.IPCC, 2021Climate Change 2021: The Physical Science Basis [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sustainable Forest Management
Forest management is a branch of forestry concerned with overall administrative, legal, economic, and social aspects, as well as scientific and technical aspects, such as silviculture, forest protection, and forest regulation. This includes management for timber, aesthetics, recreation, urban values, water, wildlife, inland and nearshore fisheries, wood products, plant genetic resources, and other forest resource values. Management objectives can be for conservation, utilisation, or a mixture of the two. Techniques include timber extraction, planting and replanting of different species, building and maintenance of roads and pathways through forests, and preventing fire. Many tools like remote sensing, GIS and photogrammetry modelling have been developed to improve forest inventory and management planning. Scientific research plays a crucial role in helping forest management. For example, climate modeling, biodiversity research, carbon sequestration research, GIS applicati ...
