Senegal's environmental issues are varied. According to the CIA world factbook pressing problems exist with: diminishing wildlife populations which are threatened by poaching, deforestation, overgrazing, soil erosion, desertification, and overfishing.[1]
Climate change

Climate change in Senegal will have wide reaching impacts on many aspects of life in Senegal. Climate change will cause an increase in average temperatures over west Africa by between 1.5 and 4 °C (3 °F and 7 °F) by mid-century, relative to 1986–2005.[2] Projections of rainfall indicate an overall decrease in rainfall and an increase in intense mega-storm events over the Sahel.[3][4] The sea level is expected to rise faster in West Africa than the global average.[5][6] Although Senegal is currently not a major contributor to global greenhouse gas emissions, it is one of the countries most vulnerable to climate change.[7][8]
Extreme drought is impacting agriculture, and causing food and job insecurity. More than 70% of the population is employed in the agricultural sector. Sea level rise and resulting coastal erosion is expected to cause damage to coastal infrastructure and displace a large percentage of the population living in coastal areas. Climate change also has the potential to increase land degradation that will likely increase desertification in eastern Senegal, leading to an expansion of the Sahara.[9]
Climate change adaptation policies and plans are important to help Senegal prepare and adapt. In 2006, Senegal submitted its National Adaptation Programme of Action (NAPA) to the United Nations Framework Convention on Climate Change.[10] The NAPA identifies water resources, agriculture, and coastal zones as the country's most vulnerable sectors.[11] In 2015, Senegal released its Intended Nationally Determined Contributions (INDC's) that indicated climate change would be treated as a national priority.[11]Deforestation and land degradation
[edit]Like other parts of West Africa and the developing world, social forces and policies are leading to deforestation and ecosystem degradation, leading to effects like Desertification and social erosion. Charcoal production,[12] alongside pressure to expand agriculture in Senegal to meet the quadrupling of population has led to increased loss of forest.[13]
In 2006, Senegal still had 45.1% —or about 8,673,000 hectares—of forest with 18.4% — or roughly 1,598,000 hectares — classified as primary forest.[14] In 2007 Senegal was losing 350,000 hectares of forest per year through slash-and-burn for farming because of its rapidly growing population.[13] Variability of rainfall compounded with issues like climate change, lead About 13% of the land - holding about 22% of the population - are now considered degraded.[15] Senegal had a 2018 Forest Landscape Integrity Index mean score of 7.11/10, ranking it 56th globally out of 172 countries.[16]
In 2016, the government warned that the Casamance forest cover would have vanished by 2018, if illegal logging continued.[17]
Mitigation
[edit]Since 1970s Senegal has lost 25% of its mangrove forests.[18] Recent efforts have been led by the organization Oceanium to replant the mangroves.[18]
The national Forest Service designed in the early 2000s was designed to democratize and decentralize forest management.[19] However, subsequent analysis by academics found that inequalities favor commercial interests and exploitation by economic forces.[20]
Overfishing
[edit]West African communities face pressure from both overfishing by local fleets as well as Asian and European fleets harvesting from fisheries in West Africa as other fisheries become overfished or collapse.[21] For example fleets in 2017 Saint-Louis, Senegal have seen a large decline in harvest, causing ripple effects on nutrition and food supply in the country, where 75% of animal protein comes from fish.[21]

Where does a four-fold increase in a country's population over half a century make itself felt most acutely? Concerning Senegal, the answer to this might well be: in the forests. At the time of independence in 1960, the West African country was home to three million people. By 1976, the figure had increased to seven million, while in July 2006 it stood at some 11.9 million. This quadrupling of the population in 47 years has led to an increase in the amount of land under cultivation, rising demand for firewood and charcoal, and accelerated urbanisation. The result: Senegal loses about 350,000 hectares of its forests annually to fires that are frequently started to clear land for farming, and more than 80,000 hectares for agricultural needs, according to the Centre for Environmental Preservation (Centre pour la sauvegarde de l'environnement, CSE).

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
