New Mapping Website Tracks Changes and Threats to Southern U.S. Forests

admin — Mon, 08 Mar 2010 16:48:56 +0000

SeeSouthernForests.org provides a new way to learn about, and protect, the forests of the southern United States.

Changes over a large area are often hard to see. This can be especially true when it comes to forests where incremental forest loss often goes unnoticed until it is too late. A new website and report by the World Resources Institute seek to change this and allow people to visualize the trends and drivers of change affecting southern forests.

Access to Information

One of our key priorities at EarthTrends is ensuring that the public have access to the type of information that can be used to understand trends, shape ideas and inform change.

Information is crucial to both development and good governance. Successful decision making can only occur if both leaders and the wider public have a complete picture of the key trends and issues impacting their nation and communities. This is particularly important when it comes to sustainably managing a country's natural resources.

However for many, particularly in low income countries, easy access is not always a given. Limited investment, poor infrastructure and the socio-economic landscape all contribute to significant segments of the population having inadequate access to information resources.

Population and Consumption

Richard Kahle — Fri, 13 Nov 2009 22:36:44 +0000

The air is full of carbon dioxide and other pollutants;
The ocean is emptying;
We have observed record setting harvests over the last few years, and yet chronic hunger persists and has recently been increasing;
The planet is experiencing the 6th great extinction;

All of these are the result of human activity.

This evidence illustrates that we have not responsibly managed, neither through governance nor technology, our environmental resources. In the absence of finding a sustainable relationship with our ecosystem, we might conclude that we have reached Earth's carrying capacity.

Sanitation: Access and Health

admin — Thu, 05 Nov 2009 16:12:41 +0000

Human waste may be a topic that people generally do not or prefer not to think about. However, its capture and disposal (often referred to in terms of sanitation) play a vital role in human health and development. The importance of sanitation as a basic human need has made it an international development priority and a key target in the United Nations Millennium Development Goals. Even though since 1990 the percent of the global population with access to improved sanitation has increased (see Figure 1.), lack of improved sanitation still threatens human health and development particularly in developing regions of the world.

Piracy and Governance in the Gulf of Aden

The number of piracy attacks reported this year have already far exceeded those of last year. According to the International Chamber of Commerce (ICC), as of September 23, 2009, 294 piratical incidents have been reported, with 97 occurring in the Gulf of Aden and 47 off of the remaining coasts of Somalia. Figure 1 shows the placements of pirate attacks within the Gulf of Aden from July to September, 2009.

Blog Action Day 2009: Climate Factoids

Samah Elsayed — Thu, 15 Oct 2009 23:49:32 +0000

Today is Blog Action Day, an annual event where bloggers worldwide combine their energies to highlight a specific issue. Over 10,000 sites from more than 150 countries, are participating in this years discussion on climate change.

As part of EarthTrends contribution we will be highlighting a few key climate change trends and statistics.

The 6th Extinction and Protected Areas

Richard Kahle — Fri, 02 Oct 2009 16:34:22 +0000

The 6th Extinction
A mass extinction is under way. Human activity, not natural phenomenon, is the difference between this extinction and the five previous big extinctions that have occurred in Earth's history. The current extinction is driven by habitat loss, overexploitation of species, invasive species and pollution. All of these, the result of humans.

The current extinction rate is between 1,000 and 10,000 times higher than the natural rate. (International Union for Conservation of Nature, IUCN) Current estimates put the extinction rate at roughly 30,000 species per year which is about three per hour. By the end of this century, about half of Earth's plant species could be gone. (Pitman and Jorgensen, 2002) For an assessment of global biodiversity, refer to the IUCN Red List.

The Recession and Short Term Trends In Energy Demand

Candy Schibli — Wed, 23 Sep 2009 13:47:56 +0000

The global economy and energy system are interdependent strands where changes in one will often cause fluctuations in the other. This relationship was highlighted by the recent economic crisis which saw cumulative effects in other spheres including world energy demand.

Information for the Virtual Water Discussion and Water Security

Candy Schibli — Fri, 14 Aug 2009 16:27:37 +0000

The World Water Council notes that the right to water "entitles everyone to sufficient, safe and acceptable, physically accessible and affordable water for personal and domestic" functions. Yet, the consumption and production of water for personal and domestic purposes depend mainly on the water and water transformation processes available for industry and agriculture. Indeed, water use in industry and agriculture has become so critical within and between countries that the term virtual water has been coined to distinguish it as a unique topic of discussion.

Energy Efficiency Measures and Global Climate Change Mitigation

Fletcher Kasmer — Thu, 30 Jul 2009 18:19:33 +0000

Two recent events held in Washington, D.C. highlighted the importance of efficiency measures to mitigate global climate change's (GCC) effects. At the Design X Tomorrow: The Future of Technology and Sustainability and McKinsey & Company's launch of Unlocking energy efficiency in the U.S. economy, the common message was simple: increasing the efficiency of energy consumption should be a major priority.
