Tracking 20 years of environmental change, UN report lays out challenges ahead
A United Nations report on environmental change has called for a concerted and rapid action that will ensure that human activities do not destroy the very environment that supports economies and sustains lives.
The report, Keeping Track of our Changing Environment: From Rio to Rio+20, compiles relevant statistical data on population, climate change, energy and food security among other key issues, to draw a picture of the current environmental landscape, spotlighting challenges ahead.
The report has been described as a timely reminder for world leaders of the areas that continue to need urgent attention such as the rapid build-up of greenhouse gases, the erosion of biodiversity and the use of natural resources, which increased by 40 per cent from 1992 to 2005, a much faster pace than population growth.
Other key issues highlighted by the report include ongoing forest loss in Africa, Latin America and the Caribbean, with a decrease of 300 million hectares of forest areas in the region since 1990, and the diminishing glaciers which have influenced the current rise in sea-levels, threatening the well-being of approximately one sixth of the world’s population.
The report also highlights areas where progress has been made and “underlines how, when the world decides to act it can dramatically alter the trajectory of hazardous trends that threaten human well-being – action to phase-out ozone-damaging chemicals being a spirited and powerful example.
It further notes that many environmental issues, which were only emerging in 1992, when the Earth Summit was held in Rio de Janeiro, are now part of mainstream policy-making in many countries due to consumer and civil society demands.
Some of these issues include the implementation of recycling practices, the commercialization of renewable energy, the rise in sales of organic products and eco-labelling, and the use of carbon trading as a way to regulate greenhouse gas emissions.
In addition, the report draws attention to the increase in the support for developing green economies, with more government investment in ways to effectively manage their resources and curb their carbon emissions as part of their broader economic development strategy.
The report is part of UNEP’s Global Environmental Outlook-5 (GEO-5) series, which assesses the state and trends of the global environment. The full GEO-5 report will be launched next May, one month ahead of Rio+20
