Harehuwa Exclosure
Harehuwa is an exclosure located in the Dogu'a Tembien ''woreda'' of the Tigray Region in Ethiopia. The area has been protected since 1999 by the local community. Environmental characteristics * Average slope gradient: 55% * Aspect: the exclosure is oriented towards the west * Minimum altitude: 2180 metres * Maximum altitude: 2300 metres * Lithology: Adigrat Sandstone Management As a general rule, cattle ranging and wood harvesting are not allowed. The grasses are harvested once yearly and taken to the homesteads of the village to feed livestock. Physical soil and water conservation has been implemented to enhance infiltration, and vegetation growth. Benefits for the community Setting aside such areas fits with the long-term vision of the communities were ''hiza’iti'' lands are set aside for use by the future generations. It has also direct benefits for the community: * improved infiltration * improved ground water availability * honey production * climate ameliorator (tempe ...

Lantana
''Lantana'' () is a genus of about 150 species of perennial flowering plants in the verbena family, Verbenaceae. They are native to tropical regions of the Americas and Africa but exist as an introduced species in numerous areas, especially in the Australian-Pacific region, South and Northeastern part of India. The genus includes both herbaceous plants and shrubs growing to tall. Their common names are shrub verbenas or lantanas. The generic name originated in Late Latin, where it refers to the unrelated ''Viburnum lantana''. Lantana's aromatic flower clusters (called umbels) are a mix of red, orange, yellow, or blue and white florets. Other colors exist as new varieties are being selected. The flowers typically change color as they mature, resulting in inflorescences that are two- or three-colored. "Wild lantanas" are plants of the unrelated genus ''Abronia'', usually called "sand-verbenas". Ecology Some species are invasive, and are considered to be noxious weeds, such a ...

Carbon Finance
Carbon finance is a branch of environmental finance that covers financial tools such as carbon emission trading to reduce the impact of greenhouse gases (GHG) on the environment by giving carbon emissions a price. Financial risks and opportunities impact corporate balance sheets, and market-based instruments are capable of transferring environmental risk and achieving environmental objectives. Issues regarding climate change and GHG emissions must be addressed as part of strategic management decision-making. The general term is applied to investments in GHG emission reduction projects and the creation (origination) of financial instruments that are tradeable on the carbon market. History The market for the purchase of carbon has grown exponentially since its conception in 1996. The following is the estimated size of the worldwide carbon market according to the World Bank: Volume (millions metric tonnes, MtCO2) * 2005: 718 (330 in Main Allowances Markets & 388 in Project ...

Emissions Reduction
Air pollution is the contamination of air due to the presence of substances in the atmosphere that are harmful to the health of humans and other living beings, or cause damage to the climate or to materials. There are many different types of air pollutants, such as gases (including ammonia, carbon monoxide, sulfur dioxide, nitrous oxides, methane, carbon dioxide and chlorofluorocarbons), particulates (both organic and inorganic), and biological molecules. Air pollution can cause diseases, allergies, and even death to humans; it can also cause harm to other living organisms such as animals and food crops, and may damage the natural environment (for example, climate change, ozone depletion or habitat degradation) or built environment (for example, acid rain). Air pollution can be caused by both human activities and natural phenomena. Air pollution is a significant risk factor for a number of pollution-related diseases, including respiratory infections, heart disease, COPD ...

Greenhouse Gas Emissions
Greenhouse gas emissions from human activities strengthen the greenhouse effect, contributing to climate change. Most is carbon dioxide from burning fossil fuels: coal, oil, and natural gas. The largest emitters include coal in China and large oil and gas companies, many state-owned by OPEC and Russia. Human-caused emissions have increased atmospheric carbon dioxide by about 50% over pre-industrial levels. The growing levels of emissions have varied, but it was consistent among all greenhouse gases (GHG). Emissions in the 2010s averaged 56 billion tons a year, higher than ever before. Electricity generation and transport are major emitters; the largest single source, according to the United States Environmental Protection Agency, is transportation, accounting for 27% of all USA greenhouse gas emissions. Deforestation and other changes in land use also emit carbon dioxide and methane. The largest source of anthropogenic methane emissions is agriculture, closely followed by ...

Land Management
Land management is the process of managing the use and development (in both urban and rural settings, but it is mostly managed in Urban places.) of land resources. Land resources are used for a variety of purposes which may include organic agriculture, reforestation, water resource management and eco-tourism projects. Land management can have positive or negative effects on the terrestrial ecosystems. Land being over- or misused can degrade and reduce productivity and disrupt natural equilibriums.

Rhus
Sumac ( or ), also spelled sumach, is any of about 35 species of flowering plants in the genus ''Rhus'' and related genera in the cashew family (Anacardiaceae). Sumacs grow in subtropical and temperate regions throughout the world, including East Asia, Africa, and North America. Sumac is used as a spice, as a dye, and in medicine. Description Sumacs are dioecious shrubs and small trees in the family Anacardiaceae that can reach a height of . The leaves are usually pinnately compound, though some species have trifoliate or simple leaves. The flowers are in dense panicles or spikes long, each flower very small, greenish, creamy white or red, with five petals. The fruits are reddish, thin-fleshed drupes covered in varying levels of hairs at maturity and form dense clusters at branch tips, sometimes called sumac bobs. Sumacs propagate both by seed (spread by birds and other animals through their droppings), and by new shoots from rhizomes, forming large clonal colonies. Taxonomy ...

Euclea Racemosa
''Euclea racemosa'' (the sea guarrie or dune guarrie) is a small to medium-sized evergreen tree that is indigenous to the Indian Ocean coast of Africa from Egypt to South Africa, as well as in Comoros, Oman and Yemen. ''Euclea racemosa'' has leathery foliage that can be exceptionally even and dense - making it an ideal plant for hedges. A dioecious tree (male and female flowers on separate trees), it produces small white flowers, which are followed by red, purple and black fruits that attract birds. The berries are used locally to make "Guarrie vinegar". The name guarrie appears to derive from the local Khoe language, in which it is spelled gwarri.
