Old Continents, New Trees

In the 1920s, when Ireland became independent, it was thought to have just 220,000 acres (90,000 hectares) of woods, covering about 1% of the land. Once-extensive forests had been shrinking for centuries…In 2017, though, almost 11% of Ireland is covered with forest, and an unknown additional amount by small woods and scattered trees. The government’s target is to cover 18% of the land area with forests by 2046. Ireland is behind schedule. Still, about 6,000 hectares of new forest ought to be planted this year, while almost none will be lost. It is part of a broad trend: the foresting of the West.

Trees are spreading in almost every European country. Because many of these forests are young, the quantity of wood in them is growing faster than their extent. Europe’s planted forests put on a little more than 1.1m cubic metres of wood per day. For comparison, the iron in the Eiffel Tower is about 930 cubic metres. Russia’s forests spread more slowly in percentage terms between 2005 and 2015, but, because Russia is so big, more than in the entire European Union in absolute terms. Forests now occupy a third of America’s land, having grown by 2% in the past decade. They are even expanding in Australia, following a long decline.

Deforestation in South America and Africa rightly gets most of conservationists’ attention. That loss is huge—equivalent to about 4.8m hectares a year, which far outweighs gains elsewhere. Yet the foresting of rich countries is still one of the world’s great land-use changes. It seems just as unstoppable as the deforestation of poorer places. It has plenty of critics, too.

The growth of forests is partly a result of changes to food markets. As the best farming areas have become more productive, and as rich countries have imported more of their food, marginal land has become unusable for ordinary agriculture…Forests are also growing because governments have favored them through laws and subsidies….Since the 1990s environmental considerations have weighed more heavily. Forests are increasingly valued as sponges for heavy rain, as wildlife habitats and as carbon sinks…

Planted forests are far from universally popular, though. Between June and October 2017, forest fires in Spain and Portugal killed more than 100 people and darkened Europe’s skies. The fires were partly blamed on the spread of non-native trees, especially eucalyptus. That Australian import, which was planted with support from the World Bank, among others, grows so quickly that trees can be harvested for pulp when less than ten years old. It also burns readily, scattering embers far afield. Portugal’s government has begun to restrict planting, in an effort to prevent the country from turning into what one green group calls “Eucalyptugal”.

The eucalyptus tree is a scapegoat for a bigger problem, argues Marc Castellnou, a fire analyst in Spain. The real trouble is that forests in Portugal and Spain have expanded quickly, with little thought for the consequences. Well-managed eucalyptus plantations are not the biggest danger—much worse are ill-managed ones with lots of underbrush and fallen wood, and the impromptu forests that grow on abandoned farms. The fires that get going in such forests jump to the treetops and burn so energetically that they cannot be stopped.

In Ireland, the criticisms are different. The country’s default tree is the sitka spruce, a fast-growing, damp-tolerant conifer from America’s Pacific Northwest. Spruce plantations are said to be devoid of life—vertical deserts of dark green. They are accused of wrecking rural communities and driving farmers off the land….

The first charge is false. Mark Wilson of the British Trust for Ornithology says that conifer plantations support more bird life per hectare than farmland, largely because they harbour more insects. Inevitably, some birds benefit more than others. The march of conifers across Britain and Ireland has increased the numbers of pine-loving birds such as siskins and crossbills. Conifers are also loved by crows—which is less obviously good, because crows raid the nests of rare birds such as curlews.

The second accusation, that trees push out other kinds of agriculture, is only partly true. Forestry subsidies and regulations have indeed distorted Ireland’s land market.

They Still Exist! Ancient Forests in Europe

The future of the the Bialowieza forest that straddles the frontier between Poland and Belarus pits competing visions of environmental stewardship and economic development, and of Poland’s path under the right-wing Law and Justice (PiS) party.

Last month the European Commission asked the European Court of Justice (ECJ) to fine Poland for ignoring an earlier order to halt logging in parts of the forest protected under EU law—in effect, nearly all of the 60,000 hectares of it that lie in Poland. In July 2017 UNESCO, the guardian of the planet’s human and natural wonders, urged the government to end logging or risk Bialowieza’s demotion from a world heritage site to one “in danger”, causing anger in Belarus, whose half of the forest would also be affected…[T] Bialowieza’s towering oaks, hornbeams and spruces, plus the European bison and other endangered species that roam beneath their canopies, offer a unique glimpse of the continent’s ecological past…

Today Poland’s forestry service insists that it, too, is being a responsible steward. The felling being condemned by Brussels was necessary, it argues, to prevent dead trunks from collapsing onto cyclists and walkers (the EU court decision exempts cutting on safety grounds, but argues that the Poles have gone much further)…

Many local residents shrug off such worries in any case. Those with ties to the long-declining lumber industry regard rotting wood as a wasted resource. The larger number engaged in tourism fret that rows of lifeless trunks put visitors off rather than lure them. “How many people will come to see dead trees?” huffs Jerzy Sirak, the mayor of Hajnowka, a town on the western edge of the forest…

Quite a few, reckons Wlodzimierz Cimoszewicz, who as prime minister in 1995-99 doubled the national park’s size to its current 10,500 hectares. Bialowieza’s value, he argues, lies in being a laboratory for natural processes, not a museum cabinet stacked with a preordained mix of species, much less a source of wood. Even with the recent uptick in revenues from logging, the forestry service spends a net 20m zlotys ($5.5m) a year on Bialowieza. Given low lumber prices, closing that deficit would require logging on a scale no one is willing to contemplate. Tourists, meanwhile, spend around 72m zlotys (20 million dollars) annually in the area, according to one study.

NGOs’ long-standing demand to place all of Bialowieza under full protection, as Belarus did with most of its part in 2012, faces opposition from local authorities that suspect eco-absolutism will curb growth. “We used to look to Poland as an example; now they look to us,” observes a Belarusian ecologist wryly.

PiS looks unmoved by environmental arguments. It dismisses protests by concerned scientists, NGOs and ordinary citizens—which range from signing open letters to chaining themselves to tree-harvesters—as political attacks by foreign and domestic opponents of its “Poland first” nationalism

The Good News: no forest loss for cocoa production

At the UN Climate Change Conference (COP23) in Bonn in November 2017 top cocoa-producing countries Côte d’Ivoire and Ghana with leading chocolate and cocoa companies have announced far-reaching Frameworks for Action to end deforestation and restore forest areas.  Central to the Frameworks is a commitment to no further conversion of any forest land for cocoa production.  The companies and governments pledged to eliminate illegal cocoa production in national parks, in line with stronger enforcement of national forest policies and development of alternative livelihoods for affected farmers. Côte d’Ivoire and Ghana combined produce nearly two-thirds of the world’s annual supply of cocoa, the main ingredient in chocolate and a range of other consumer products…

Up-to-date maps on forest cover and land-use, as well as socio-economic data on cocoa farmers and their communities will be developed and publicly shared by the governments. Chocolate and cocoa industry agree to put in place verifiable monitoring systems for traceability from farm to the first purchase point for their own purchases of cocoa, and will work with the governments of Côte d’Ivoire and Ghana to ensure an effective national framework for traceability for all traders in the supply chain.

The two governments and companies agree through the Frameworks to accelerate investment in long-term sustainable production of cocoa, with an emphasis on “growing more cocoa on less land,”. Key actions include provision of improved planting materials, training in good agricultural practices, and development and capacity-building of farmers’ organizations.  Sustainable livelihoods and income diversification for cocoa farmers will be accelerated through food crop diversification, agricultural inter-cropping, development of mixed agro-forestry systems, and other income generating activities designed to boost and diversify household income while protecting forests.

The governments and companies, which represent and estimated 80+ percent of global cocoa usage, commit to full and effective consultation and participation of cocoa farmers in the process…The governments and companies have committed to a comprehensive monitoring process, including a satellite-based monitoring system to track progress on the overall deforestation target, and annual publicly disclosed reporting on progress and outcomes related to the specific actions in each Framework.

Excerpts from Cocoa and Forests Initiative

Companies that have joined the initiative include; Cargill, General Mills, Godiva, Hershey, Mars, Mondelēz, and Nestlé.

Don’t Cut that Tree!

A revolutionary new approach to measuring changes in forest carbon density has helped scientists determine that the tropics now emit more carbon than they capture, countering their role as a net carbon “sink.”*

“These findings provide the world with a wakeup call on forests,” said scientist Alessandro Baccini, the report’s lead author….Forests are the only carbon capture and storage ‘technology’ we have in our grasp that is safe, proven, inexpensive, immediately available at scale, and capable of providing beneficial ripple effects—from regulating rainfall patterns to providing livelihoods to indigenous communities.”

Using 12 years (2003-2014) of satellite imagery, laser remote sensing technology and field measurements, Baccini and his team were able to capture losses in forest carbon from wholesale deforestation as well as from more difficult-to-measure fine-scale degradation and disturbance …from smallholder farmers removing individual trees for fuel wood. These losses can be relatively small in any one place, but added up across large areas they become considerable.

[T] he researchers discovered that tropics represent a net source of carbon to the atmosphere — about 425 teragrams of carbon annually – which is more than the annual emissions from all cars and trucks in the United States.

Supply Chains Live: combating deforestation

366 companies, worth $2.9 trillion, have committed to eliminating deforestation from their supply chains, according to the organization Supply Change. Groups such as the Tropical Forest Alliance 2020, the Consumer Goods Forum and Banking Environment Initiative aim to help them achieve these goals.  Around 70 percent of the world’s deforestation still occurs as a result of production of palm oil, soy, beef, cocoa and other agricultural commodities. These are complex supply chains.  A global company like Cargill, for example, sources tropical palm, soy and cocoa from almost 2,000 mills and silos, relying on hundreds of thousands of farmers. Also, many products are traded on spot markets, so supply chains can change on a daily basis. Such scale and complexity make it difficult for global corporations to trace individual suppliers and root out bad actors from supply chains.

Global Forest Watch (GFW), a WRI-convened partnership that uses satellites and algorithms to track tree cover loss in near-real time, is one example. Any individual with a cell phone and internet connection can now check if an area of forest as small as a soccer penalty box was cleared anywhere in the world since 2001. GFW is already working with companies like Mars, Unilever, Cargill and Mondelēz in order to assess deforestation risks in an area of land the size of Mexico.

Other companies are also employing technological advances to track and reduce deforestation. Walmart, Carrefour and McDonalds have been working together with their main beef suppliers to map forests around farms in the Amazon in order to identify risks and implement and monitor changes. Banco do Brasil and Rabobank are mapping the locations of their clients with a mobile-based application in order to comply with local legal requirements and corporate commitments. And Trase, a web tool, publicizes companies’ soy-sourcing areas by analyzing enormous amounts of available datasets, exposing the deforestation risks in those supply chains…

[C]ompanies need to incorporate the issue into their core business strategies by monitoring deforestation consistently – the same way they would track stock markets.

With those challenges in mind, WRI and a partnership of major traders, retailers, food processors, financial institutions and NGOs are building the go-to global decision-support system for monitoring and managing land-related sustainability performance, with a focus on deforestation commitments. Early partners include Bunge, Cargill, Walmart, Carrefour, Mars, Mondelēz, the Inter-American Investment Corporation, the Nature Conservancy, Rainforest Alliance and more.  Using the platform, a company will be able to plot the location of thousands of mills, farms or municipalities; access alerts and dashboards to track issues such as tree cover loss and fires occurring in those areas; and then take action. Similarly, a bank will be able to map the evolution of deforestation risk across its whole portfolio. This is information that investors are increasingly demanding.

All for the Oil: forest fires

Indonesia forest fire. image from wikipedia

…In 2015 a dry spell caused by the El Niño weather pattern made Indonesia’s forest fires  especially severe. Smoke settled over Singapore for months and even reached Cambodia, Vietnam and the Philippines. At least 2m hectares of forest were burned. Dozens of people were killed and hundreds of thousands sickened. For much of October 2015 greenhouse gases released by those fires exceeded the emissions of the entire American economy. The losses over five months of fires amounted to around 2% of the country’s GDP…[The event has labeled  the 2015 Southeast Asian haze]

Between 2001 and 2014, Indonesia lost 18.5m hectares of tree cover—an area more than twice the size of Ireland. In 2014 Indonesia overtook Brazil to become the world’s biggest deforester.

One of the reasons for those forest fires is economic. The country produces well over half the world’s palm oil, a commodity used in cooking and cosmetics, as a food additive and as a biofuel. It accounts for around 4.5% of Indonesia’s GDP, and demand is still rising. To meet it, Indonesian farmers set fires to clear forest and make way for new plantations. Often these forests grow on peatlands, which store carbon from decayed organic matter; in tropical regions these hold up to ten times as much carbon as surface soil. Draining peatlands releases all of that carbon. The peat also becomes a fuel, so it is not just felled trees that are burning but the ground itself.

But politics also plays a part. … The president declared a moratorium on peatland-development licences and called for peat forests to be restored, even as his agriculture minister pointed out that burned peatland can be used for corn and soyabean planting….

Civil-society groups have had some success. At least 188 Indonesian palm-oil companies have made some sort of sustainability pledge, including five large multinational firms that in 2014 signed the Indonesian Palm Oil Pledge (IPOP), which commits them to avoiding deforestation and planting oil palms on peatland. Together those five firms account for 80% of Indonesia’s palm-oil exports.All the same, deforestation continues. Perversely, it may even have increased temporarily, as companies cleared as much land as they could before the agreement took effect. Besides, opaque supply chains allow companies to buy palm oil from suppliers not bound by IPOP.

How to Discover an Illegal Logger

Image from http://blog.globalforestwatch.org/2016/02/how-did-the-worlds-forests-change-last-week-new-alerts-show-us/?utm_campaign=glad%20alerts&utm_source=blog&utm_medium=caption&utm_content=gif

Tropical forests nearly the size of India are set to be destroyed by 2050 if current trends continue causing species loss, displacement and a major increase in climate-changing greenhouse gas emissions.  Prior to the launch of the Global Land Analysis and Discovery (GLAD) alerts, researchers would have to manually track images of logging in specific areas.

The new process, developed by scientists at the University of Maryland and Google, uses an algorithm to analyze weekly updates of satellite images and sends automatic notifications about new logging activity.”This is a game changer,” said Matt Finer from the Amazon Conservation Association, an environmental group.

His organization tracks illegal logging in Peru, sending images of deforestation to policymakers, environmentalists and government officials to try and protect the Amazon rainforest.  In the past, he would rely on tips from local people about encroachment by loggers, then look at older satellite images to try and corroborate the claims.

“With this new data we can focus on getting actionable information to policy makers,” Finer told the Thomson Reuters Foundation.  “We have seen how powerful these images can be,” he said, citing a case where his group brought pictures of illegal gold miners cutting down trees to the Peruvian government, who then removed the miners.
