Environmentalsustainability wemean meetingcurrent humanneeds withoutundermining thecapacity of theenvironment toprovide for thoseneeds over the longterm.
SOCIO- BIO- PHYSICALProblem exists in the ECONOMICenvironment. Causecreated by human andbio physicalconditions. If physicalconditions are notfavorable means theresources has beenused injudiously and if ECOSYSTEMfavorable meanspeople are uneducated.It is true. No one will agree to use resources on eco-friendly basis.
•Change in landcover•Pollution•Invasive alienspecies•Over appropriationor inappropriateexploitation ofnatural resources•Climate change
• Get Safe water 1in 5lakhs.•One billion live in Dryland.•1.2 billion live in Rs 50per day• Poor families oftenlack the resourcesrequired.• Limited access tocredit• Poor people relyextensively on naturalresources. However overextraction of resourcesdisrupt the environment
• Food security is integrallylinked to environmentalsustainability.• > 2 billion poor people relydirectly on agriculture forsubsistence .• The ecosystem services arecritical for productionincludes freshwater for cropirrigation, maintenance ofsoil fertility , provision ofcrop genetic diversity; croppollinators, pest control andclimate regulation. These form ofenvironmental degradationdecrease food availability,sometimes irreversibly,complicating efforts to fighthunger.
Environmentaldegradation adverselyaffects human healththrough exposure tobacteria, parasites anddisease vectors, chemicalagents (such as heavymetals, pesticides in water,food, air and soils), andphysical and safetyhazards (such as fire,radiation and naturaldisasters) Many of thediseases, such as malaria,dengue and encephalitisare on the rise because ofhuman disruption ofnatural ecosystems.
• Fertility is highest in thepoorest countries andamong the poorest people inpoor and middle incomesocieties.• Many developing countriesare experiencing significantrural to urban migration.• These demographic shiftshave key implications forresource use.• Increased food demand canencourage agriculturalintensification & humanpressures on ecosystems andenvironment will grow.
• It drive environmentalchange in at least siximportant ways –•Increases consumptionand production &intensifies resourceexploitation.• changes in land cover,its use and generateswaste.• environmentallydamaging subsidies•increased internationaltrade and financial flowsshift consumption• exogenous shift inconsumer preferences
• Environmentalsustainability requiresdramatic changes in theways societies and citizensmanage their biodiversity,wastes and byproducts ofproduction andconsumption process, andconsumption patterns.• Also requires addressingthe direct and indirectdrivers, the underlyingcauses of environmentalproblems.
Train, recruit and retain environment experts Secure sufficient funding for environmental institutions. Reform government institutions and improve interagency coordination Improve governance and gender equality. Account for the cost of environmental degradation in national accounts. Introduce payment systems for ecosystem services and tax reform. Phase out environment damaging subsidies. Improve national and international regulatory framework. Establish mechanisms for science and technology advices. Train decision makers for environmental management. Provide public access to information. Improve extension, training and services. Science and technology must be at the center of any strategy for environmental sustainability.Universities and other institutions of higher learning should applythemselves directly to sustainability goals.
• Increase use of sustainable agriculture techniques topreserve natural assets.• Increase real income of informal forest sector of atleast 200percent by 2020.• Protection and restoration of ecologically viablerepresentative areas of all major forest, shrub land andpasture vegetation types and their biodiversity.• Slowing fresh water degradation requires reducingdemand, especially in cropping systems; controllingpollution; and protecting aquatic environments.• Action should be taken to reduce exposure to toxicchemicals and child mortality caused by indoor air pollutionand water born diseases.
