The government of Nova Scotia announced an ambitious plan earlier this month to protect 245,000 hectares of forest and park land, establishing the Canadian province as a conservation leader in one of the world’s most heavily forested nations. Roughly 14 percent of all land in Nova Scotia will now be legally protected from development, making it the province with the second-highest percentage of land devoted to protected areas in Canada, after British Columbia.
This news is significant for conservationists and for the vast number of Canadians who depend on these forests for clean air, water, and a bounty of other resources. It also illustrates a powerful truth: precise, science-based maps are an essential component of good forest management and planning.
Over the past few days, WRI has been tracking the location of forest and land fires on Sumatra, an island in western Indonesia. In this update, WRI examines the historical trends of forest fires in Sumatra. Read our previous analysis.
Fires continue to burn in Indonesia, spreading haze and suffering across the country and into Malaysia and Singapore. New research from the World Resources Institute reveals troubling trends about the blazes:
The current fires are not beyond the normal historic range for fires in the region, but that may change as the fires continue to burn heavily.
The recent fires are part of a longstanding, endemic crisis of forest fires and land clearing in Indonesia, and bold action is needed to prevent the crisis from escalating.
In this new analysis, WRI examines the historical trends of forest fires in Sumatra. Rapid analysis from WRI finds that the current forest fires observed in the Riau Province fit into a larger pattern of widespread forest and land fires. However, June 2013 is on track to be one of the worst months on record since 2001. Evaluation of recent wind patterns explains why the fires’ impact was felt so acutely in Singapore.
WRI explored these trends using two key data sets:
Historic fire alerts from NASA’s Active Fire Data, which shows fire alerts for the period of January 1, 2001 until the present.
Information on air dispersion to Singapore derived from NOAA’s HYSPLIT model, which takes into account meteorological data and can be used to estimate the most likely path that air traveled to reach a particular location at a given time.

Hari Jumat yang lalu, World Resources Institute (WRI) mempublikasikan data detil terkait lokasi peringatan titik api di Sumatera yang telah menyebabkan kabut asap yang sangat mengganggu dan berpotensi beracun di wilayah Indonesia, Singapura, dan Malaysia. Pemerintah ketiga negara, perusahaan-perusahaan, maupun media semua berlomba untuk mencari data untuk memahami penyebab dan lokasi sebaran titik api, serta memutuskan siapa yang seharusnya bertanggung jawab.
Selama beberapa hari terakhir ini, WRI telah melacak lokasi sebaran kebakaran hutan dan lahan yang terjadi di Sumatera, sebuah pulau di bagian barat Indonesia. Dalam perkembangan terbaru ini, WRI menganalisis tren historis kebakaran hutan yang terjadi di Sumatera. Baca analisa sebelumnya.
Analisis terbaru dari WRI menunjukkan adanya perkembangan sebaran peringatan titik api di Sumatera dari waktu ke waktu serta kaitannya dengan konsesi perusahaan. Dua data penting dalam analisis ini antara lain:

Penduduk di,Singapura, sebagian dari Indonesia dan Malaysia sedang mengalami kabut asap yang menganggu aktivitas sehari-hari akibat kebakaran hutan. Tingkat kualitas udara di Singapura telah jatuh ke tingkat terburuk yang pernah tercatat di pulau tersebut sedangkan bandara di Indonesia dan beberapa sekolah di Malaysia harus ditutup. Hampir semua kebakaran yang terjadi baru-baru ini (12-20 Juni) berasal dari titik api di Sumatera.
Media massa banyak memuat debat sengit mengenai lokasi, sebab, dan sifat kebakaran. Saat ini WRI telah menyusun beberapa data awal yang menunjukkan beberapa pola menarik. Data awal menunjukkan kebakaran yang terjadi relatif sedikit di kawasan lindung dan konsesi penebangan. Lebih dari setengah dari peringatan titik api yang ditemukan terjadi pada hutan tanaman industri dan perkebunan kelapa sawit. Meskipun membakar hutan bagi perusahaan di Indonesia merupakan perbuatan ilegal, perusahaan di masa lalu telah diketahui menggunakan api untuk pembukaan lahan. Hal ini akan menjadi penting untuk mengumpulkan informasi lebih lanjut mengenai lokasi kebakaran dan penyebabnya. Informasi ini dapat memberi implikasi penting bagi perusahaan-perusahaan dan badan pemerintah yang terlibat.

People in Indonesia, Singapore, and parts of Malaysia are currently suffering from debilitating levels of haze resulting from forest fires. Air quality levels in Singapore have deteriorated to the worst levels ever recorded on the island, while local airports in Indonesia and some schools in Malaysia have had to close. Almost all of the recent fires (June 12-20) have occurred in Sumatra, an island in western Indonesia.
While there’s been heated debate on the location, cause, and nature of the fires, WRI has compiled some initial data that reveals that there are some patterns. Relatively few fires have occurred in protected areas and selective logging concessions. Furthermore, half of the fires are burning on timber and oil palm plantations. Although it is illegal for companies in Indonesia to start forest or land fires, several companies have used fires for land clearing in the past. It will be important to gather more detailed information about the exact location of the fires and their causes, which could have important implications for the companies and government agencies involved.
A Look Inside the Forest Fire Data
WRI gathered information from NASA’s Active Fire Data, which uses satellite data to pinpoint the location of fires in near real time, together with the Indonesian Ministry of Forestry’s concession maps for oil palm, logging concessions, and timber plantation licenses. We counted the number of NASA fire alerts in each concession in Indonesia and tabulated the results.

We know less about one of world's most pressing challenges today than we did 10 years ago. It's no secret that water - or the lack thereof - will be one of the defining issues of the 21st century. And yet, the United Nations World Water Report, in 2009, stated that when it comes to water, "less is known with each passing decade."
The World Economic Forum recently named the water supply crises as one of the top risks facing the planet - edging out issues like terrorism and systemic financial failure. Water risks permeate almost every aspect of global society. We got a taste last year with crops scorched by drought, shipping lanes threatened and energy plants shut down by low water levels, and coastlines devastated by flooding. Exacerbated by climate change and population growth, such crises will become more common and costly. Yet, the world largely lacks the data we need to monitor, understand, and respond to these water challenges. We are flying blind when it comes to global water issues.
Today marks the 20th anniversary of the first World Water Day, an international celebration designed to draw attention to the importance of freshwater resources. However, for a large and growing proportion of the world’s population, every day is a World Water Day. Difficult, complex water challenges including drought, groundwater depletion, pollution, and clean drinking water availability are growing in urgency and seriousness all around the world. Some even argue that we should boycott World Water Day – that our water problems are too serious to try and confine to a single day.
Although it’s true that we must keep water in mind during the other 364 days of the year, World Water Day can be useful. It helps raise awareness and serves as an annual reminder of the water problems we must collectively solve. Plus, picking a single theme – this year’s is cooperation – helps break down a very complex topic into more accessible, comprehensible pieces.
In keeping with the theme of helping make complex issues more approachable and understandable, WRI is marking this year’s World Water Day by launching the first in a new series of videos we’re calling “What’s the Big Idea?” These brief videos will feature WRI staff members explaining some of the complex, global challenges we are working to understand and solve. Our first “What’s the Big Idea?” video explains the concept of water risk and the array of challenges it poses. We also highlight a potential solution: WRI’s Aqueduct mapping tool, which helps companies, investors, governments, and others better understand and manage their water risks.

This piece explores how advances in technology can curb illegal logging, written in honor of the first International Day of Forests. It originally appeared on The Guardian's Sustainable Business Blog.
Our future is inextricably linked to forests. The social and economic benefits they provide are essential to realizing a sustainable century. A key litmus test of our commitment to this future is our response to a growing, global threat: illegal logging and the criminal timber trade.
Forests are a vital source of biodiversity and livelihoods. More than 1.6 billion people depend on forests for their livelihoods, including 60 million indigenous people who are wholly dependent on forests. They are also natural carbon storage systems and key allies in combating climate change. They are vast, nature-based water utilities assisting in the storage and release of freshwater to lakes and river networks.
While deforestation is slowing in some places – most notably Brazil – it still remains far too high. The loss of forests is responsible for up to 17 percent of all human-made greenhouse gas emissions, 50 percent more than that from ships, aviation and land transport combined.
In January, Brian Richter, director of freshwater strategies at The Nature Conservancy, spelled out four water resolutions through a thought-provoking series of blog posts. One of those resolutions was to better understand and communicate the differences between water use and water consumption. This is a particularly important issue, as there has been a lot of discussion lately about water scarcity, water stress, and the risks associated with them.
So what do ”water use” and “water consumption” mean?
“Water use” describes the total amount of water withdrawn from its source to be used. Measures of water usage help evaluate the level of demand from industrial, agricultural, and domestic users. For example, a manufacturing plant might require 10,000 gallons of freshwater a day for cooling, running, or cleaning its equipment. Even if the plant returns 95 percent of that water to the watershed, the plant needs all 10,000 gallons to operate.
“Water consumption” is the portion of water use that is not returned to the original water source after being withdrawn. Consumption occurs when water is lost into the atmosphere through evaporation or incorporated into a product or plant (such as a corn stalk) and is no longer available for reuse. Water consumption is particularly relevant when analyzing water scarcity and the impact of human activities on water availability. For example, irrigated agriculture accounts for 70 percent of water use worldwide and almost 50 percent of that is lost, either evaporated into the atmosphere or transpired through plant leaves.
