Environmental issues in Sri Lanka
forest covers sri lanka greatly reduced legal well illegal forest clearing.due deforestation sri lanka size land covered natural forests decreased .partly caused british colonialism increased amount tea coffee rubber plantations.natural forest cover decreased .sri lankas area covered forests number includes forest plantations.drivers recent forest degradation increase population road construction timber production agricultural development forest cleaning private businessmen.
Environmental issues in Sri Lanka
even though conservation areas management partly insufficient.extensive deforestation leads rise average surface temperature.deforestation also responsible increase greenhouse gas emissions trees remove co air.clear cutting areas co returns air thereby increases atmospheric carbon concentration.the government sri lanka adopted target increase size land covered forests .order achieve government intends reforest degraded forests increase urban forests improve forest plantations.sri lanka forest landscape integrity index mean score .
Environmental issues in Sri Lanka
ranking th globally countries.mangrove degradation sri lankas mangrove forests small trees grow coastal water decreased since .size mangrove ecosystems reduced implementation agriculture aquaculture systems like fisheries.shrimp aquaculture projects one biggest threats.shrimp business growing fast high demand high profits.
Environmental issues in Sri Lanka
one negative impacts shrimp farms mangroves destroyed farms built.mangroves however important people living close coast.reason mangroves offer products used cooking building houses fodder well fish food items.also offer protection floods pollutants.moreover mangroves important ecosystems host animals like fish crab shrimp.in government sri lanka reached agreement private companies nongovernmental organizations researchers members affected communities.agreement protects mangrove forests sri lanka law.
Environmental issues in Sri Lanka
moreover agreed launch mangrove reforestation activities create alternative sources income locals.coral reef destruction coral reefs threatened human activities destructive fishing methods coralmining pollution unsustainable management practices.extensive aquaculture biggest threat coral reefs.shrimp farms especially destructive coral reefs.coral reefs important coastal population.provide food protect coast popular destination tourists therefore important peoples income.
Environmental issues in Sri Lanka
sri lankans live along coast population growing greater negative consequences coral reefs.soil degradation parts dry zone well wet zone damaged soil degradation.soil erosion sri lanka times bigger would without human influence.negative impacts agriculture well peoples livelihood.soil degradation mainly caused unsustainable agricultural practices high intensity rainfall indirectly caused population growth results increased consumption.tree plantation tea rubber plantation cause low rates soil erosion.
Environmental issues in Sri Lanka
higher rates soil erosion caused crops harvested annually like potatoes vegetables tobacco.soil degradation dry zone leads desertification.loss soil also big problem near watersheds lot hydro power plants built watersheds.air pollution air pollution problem sri lankas cities mostly caused vehicles.number motor vehicles almost tripled also led increase traffic jams.
Environmental issues in Sri Lanka
use old vehicles poor quality gas intensify negative consequences.major air pollutants sri lanka oxides carbon oxides nitrogen oxides sulfur particulates inorganic compounds hydrocarbons secondary pollutant photochemical smog.pollutants negative impact peoples health cause respiratory illnesses asthma even death.dust falls also issue areas high traffic density.besides outdoor pollution indoor pollution also concern.pollutants listed even worse impacts inside motor vehicles buildings.air pollution inside buildings severe problem firewood used cooking.
Environmental issues in Sri Lanka
households burned firewood cooking sets free many fine particles cause respiratory illnesses cancer.water pollution domestic activities industry agriculture cause water pollution sri lanka.rivers lakes affected pollutants.pollutants end lakes sewage vegetable waste waste hospitals.pollution lakes sri lanka leads algal blooms reduces oxygen content negative consequences fish populations.kelani river especially polluted flows industrial areas.
Environmental issues in Sri Lanka
industrial waste often discharged river treated untreated.moreover dumps located close rivers negative influences water quality.large amounts pesticides used agricultural sector also get water rivers lakes.groundwater surface water also polluted heavy use fertilizer pesticides storm runoffs.coastal marine waters threatened pesticides fertilizer industrial waste runoffs waste dumps.
Environmental issues in Sri Lanka
rivers flow sea deteriorate sea water.oil spills chemicals nonbiodegradable waste plastic also decrease quality sri lankas seawater.microplastic pollution resulted drastic reduction fish stocks.in households sri lanka got water pipes.even water come pipe local suppliers monitored efficiently.part population get clean drinking water.
Environmental issues in Sri Lanka
waste management sri lanka faces managerial problems waste collection waste disposal.a study revealed household waste management percentage access waste collection even smaller rural areas .increased waste generation caused high population growth industrialization urbanization increased consumption.provinces local authorities overstrained large amounts.collected waste often brought open dumps treated.moreover dumps located environmentally sensitive locations close residential areas.problems caused lack governmental regulations public commitment also lack technical knowledge low financial resources little suitable space waste disposal sites.
Environmental issues in Sri Lanka
effects poor waste management waste laying streets waterways swamps.results influence aesthetic landscape decrease biodiversity cause health problems negative impacts sri lankas tourist industry.study shows areas without waste collection majority people dump waste going landfill backyard.plastics paper often burned also disposed backyard.moreover green waste burned household southern provinces access waste collection.sri lankas government aims address problems implementing waste sorting systems households improved waste collection municipalities cities composting systems systematic treatment hazardous waste industry clinics.
Environmental issues in Sri Lanka
overfishing sri lanka experiencing declines fish populations due overfishing.climate change vulnerability sri lankas geographic location makes vulnerable climate change impacts.expected impacts increase temperature frequent extreme weather events like floods cyclones well sea level rise.sea level rise especially critical sri lankas coastal regions.impacts negatively influence agriculture fisheries tourism peoples livelihood environment.
Environmental issues in Sri Lanka
impacts agriculture fisheries turn influence food security exports crops fishes.negative consequences environment include biodiversity loss ecosystem degradation water cycle disturbances.sri lanka set goals intended nationally determined contributions indc implement climate change mitigation adaptation strategies order prevent severe climate change impacts.government already implemented regulations guidelines like national climate change policy sri lanka climate change vulnerability profiles technology action plans climate change adaption mitigation .moreover steps taking reduce possible impacts climate change sri lanka.steps include limited building resilient infrastructure actions ensure human health food security climate change impacts like floods cyclones protection environment tourism sector.
