A carbon sink is a natural or artificial process that "removes a greenhouse gas, an aerosol or a precursor of a greenhouse gas from the atmosphere". These sinks form an important part of the natural carbon cycle. An overarching term is carbon pool, which is all the places where carbon on Earth can be, i.e. the atmosphere, oceans, soil, plants, and so forth. A carbon sink is a type of carbon pool that has the capability to take up more carbon from the atmosphere than it releases.
Reforestation is the practice of restoring previously existing forests and woodlands that have been destroyed or damaged. The prior forest destruction might have happened through deforestation, clearcutting or wildfires. Two important purposes of reforestation programs are for harvesting of wood or for climate change mitigation purposes. Reforestation can also help with ecosystem restoration. One method for reforestation is to establish tree plantations, also called plantation forests. They cover about 131 million ha worldwide, which is 3 percent of the global forest area and 45 percent of the total area of planted forests.
Logging is the process of cutting, processing, and moving trees to a location for transport. It may include skidding, on-site processing, and loading of trees or logs onto trucks or skeleton cars. In forestry, the term logging is sometimes used narrowly to describe the logistics of moving wood from the stump to somewhere outside the forest, usually a sawmill or a lumber yard. In common usage, however, the term may cover a range of forestry or silviculture activities.
Land development is the alteration of landscape in any number of ways such as:
Afforestation is the establishment of a forest or stand of trees (forestation) in an area where there was no recent tree cover. In comparison, reforestation means re-establishing forest that have either been cut down or lost due to natural causes, such as fire, storm, etc. There are three types of afforestation: Natural regeneration, agroforestry and tree plantations. Afforestation has many benefits. In the context of climate change, afforestation can be helpful for climate change mitigation through the route of carbon sequestration. Afforestation can also improve the local climate through increased rainfall and by being a barrier against high winds. The additional trees can also prevent or reduce topsoil erosion, floods and landslides. Finally, additional trees can be a habitat for wildlife, and provide employment and wood products.
Carbon sequestration is the process of storing carbon in a carbon pool. It plays a crucial role in mitigating climate change by reducing the amount of carbon dioxide in the atmosphere. There are two main types of carbon sequestration: biologic and geologic. Biologic carbon sequestration is a naturally occurring process as part of the carbon cycle. Humans can enhance it through deliberate actions and use of technology. Carbon dioxide is naturally captured from the atmosphere through biological, chemical, and physical processes. These processes can be accelerated for example through changes in land use and agricultural practices, called carbon farming. Artificial processes have also been devised to produce similar effects. This approach is called carbon capture and storage. It involves using technology to capture and sequester (store) CO
2 that is produced from human activities underground or under the sea bed.
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, 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.
Deforestation in Nigeria refers to the extensive and rapid clearing of forests within the borders of Nigeria. This environmental issue has significant impacts on both local and global scales.
Carbon dioxide removal (CDR) is a process in which carbon dioxide is removed from the atmosphere by deliberate human activities and durably stored in geological, terrestrial, or ocean reservoirs, or in products. This process is also known as carbon removal, greenhouse gas removal or negative emissions. CDR is more and more often integrated into climate policy, as an element of climate change mitigation strategies. Achieving net zero emissions will require first and foremost deep and sustained cuts in emissions, and then—in addition—the use of CDR. In the future, CDR may be able to counterbalance emissions that are technically difficult to eliminate, such as some agricultural and industrial emissions.
Oluwa Forest Reserve is located in Ondo State, Nigeria and covers over 829 km2 (320 sq mi). It is part of the Omo, Shasha and Oluwa forest reserves, although it has become separated from the Omo and Shasha reserves. The three reserves contain some of the last remaining forest in the area. Although they are biologically unique, they are threatened by logging, hunting and agriculture. The natural vegetation of the area is tropical rainforest. However, the natural vegetation of the area except for the areas devoted to forest reserve has now been reduced to secondary regrowth forest and fallow regrowth at varying stages of development or replaced by perennial and annual crops.
Mangrove restoration is the regeneration of mangrove forest ecosystems in areas where they have previously existed. Restoration can be defined as "the process of assisting the recovery of an ecosystem that has been degraded, damaged, or destroyed." Mangroves can be found throughout coastal wetlands of tropical and subtropical environments. Mangroves provide essential ecosystem services such as water filtration, aquatic nurseries, medicinal materials, food, and lumber. Additionally, mangroves play a vital role in climate change mitigation through carbon sequestration and protection from coastal erosion, sea level rise, and storm surges. Mangrove habitat is declining due to human activities such as clearing land for industry and climate change. Mangrove restoration is critical as mangrove habitat continues to rapidly decline. Different methods have been used to restore mangrove habitat, such as looking at historical topography, or mass seed dispersal. Fostering the long-term success of mangrove restoration is attainable by involving local communities through stakeholder engagement.
Forest conservation is the practice of planning and maintaining forested areas for the benefit and sustainability of future generations. Forest conservation involves the upkeep of the natural resources within a forest that are beneficial for both humans and the ecosystem. Forests provide wildlife with a suitable habitat for living which allows the ecosystem to be biodiverse and benefit other natural processes. Forests also filter groundwater and prevent runoff keeping water safe for human consumption. There are many types of forests to consider and various techniques to preserve them. Of the types of forests in the United States, they each face specific threats. But, there are various techniques to implement that will protect and preserve them.
Deforestation is a primary contributor to climate change, and climate change affects the health of forests. Land use change, especially in the form of deforestation, is the second largest source of carbon dioxide emissions from human activities, after the burning of fossil fuels. Greenhouse gases are emitted from deforestation during the burning of forest biomass and decomposition of remaining plant material and soil carbon. Global models and national greenhouse gas inventories give similar results for deforestation emissions. As of 2019, deforestation is responsible for about 11% of global greenhouse gas emissions. Carbon emissions from tropical deforestation are accelerating.
The Buffelsdraai Community Reforestation Project was initiated in 2008 to alleviate climate change impacts associated with hosting elements of the 2010 FIFA World Cup in Durban. The proposed carbon offset was to be achieved through the planting of more than 500 000 indigenous trees within the buffer zone of the Buffelsdraai Landfill Site. Restoring the forest ecosystem was identified as a way of "absorbing event-related greenhouse gas emissions while enhancing the capacity of people and biodiversity to adapt to the inevitable effects of climate change".
Carbon farming is a set of agricultural methods that aim to store carbon in the soil, crop roots, wood and leaves. The technical term for this is carbon sequestration. The overall goal of carbon farming is to create a net loss of carbon from the atmosphere. This is done by increasing the rate at which carbon is sequestered into soil and plant material. One option is to increase the soil's organic matter content. This can also aid plant growth, improve soil water retention capacity and reduce fertilizer use. Sustainable forest management is another tool that is used in carbon farming. Carbon farming is one component of climate-smart agriculture. It is also one of the methods for carbon dioxide removal (CDR).
Proforestation is the practice of protecting existing natural forests to foster continuous growth, carbon accumulation, and structural complexity. It is recognized as an important forest based strategy for addressing the global crises in climate and biodiversity. Forest restoration can be a strategy for climate change mitigation. Proforestation complements other forest-based solutions like afforestation, reforestation and improved forest management.
Namatale Central Forest Reserve is a forest located in Mbale district, Uganda. It is a significant natural resource that plays a crucial role in the region's ecosystem and biodiversity conservation efforts.
Reforestation in Nigeria employs both natural and artificial methods. Reforestation involves the deliberate planting of trees and restoring forested areas that have been depleted or destroyed. It involves a planned restocking of the forest to ensure sustainable supply of timber and other forest products. Reforestation, in essence, involves replenishing forests to guarantee a consistent and sustainable supply of timber and various other forest resources. This objective can be accomplished through either natural regeneration techniques or artificial regeneration methods. Both of these approaches have been utilized in the reforestation efforts within Nigeria's forests. At the initiation of the reforestation program in Nigeria, the natural regeneration approach was chosen for two primary reasons. Firstly, it aimed to preserve the rainforest in its original state by allowing it to regenerate naturally from the existing seed bank in the soil. Secondly, and of significant importance, this method was selected due to budgetary constraints, as there were insufficient funds available to establish plantations through direct means.
Fruit production is a major driver of deforestation around the world. In tropical countries, forests are often cleared to plant fruit trees, such as bananas, pineapples, and mangos. This deforestation is having a number of negative environmental impacts, including biodiversity loss, ecosystem disruption, and land degradation.
Climate change effects on tropical regions includes changes in marine ecosystems, human livelihoods, biodiversity, degradation of tropical rainforests and effects the environmental stability in these areas. Climate change is characterized by alterations in temperature, precipitation patterns, and extreme weather events. Tropical areas, located between the Tropic of Cancer and the Tropic of Capricorn, are known for their warm temperatures, high biodiversity, and distinct ecosystems, including rainforests, coral reefs, and mangroves.
