Governments must tackle environmental degradation as it threatens region’s future
Many Asian cities will ring in the New Year with high levels of air pollution, which contributes to potentially life-shortening health problems, from heart disease to severe asthma. Seasonal cold weather impedes dispersal of pollutants in the air, and so tends to increase levels of carbon monoxide and particulates, including tiny particles that can find their way into human lungs.
Asia, given the contamination levels and large populations, is the epicenter of the global air pollution problem. City dwellers are breathing polluted air contaminated with particulates multiple times greater in concentration than the World Health Organization’s safe limit.
The air pollution problem is intimately linked to Asia’s larger crisis arising from its deteriorating natural environment. This degradation poses a potent threat to Asia’s future.
For example, one factor that has contributed to New Delhi’s dangerous air pollution levels is the disappearance of 31 hills in northwest India’s Aravalli range due to mining. India’s Supreme Court in October halted all further mining in the 690-kilometer-long range, which has lost its forest cover, resulting in summertime dust storms in the Indian capital and other cities in the region.
Similarly, the ever-increasing sand squalls that blanket Beijing are linked to misguided government policies that have inadvertently promoted desertification in China’s northwest, north and northeast (officially called the “three norths”). The Gobi Desert’s advance toward Beijing has been aided since the Mao Zedong era by subsidized natural resources to agriculture and industry, thus promoting inefficiency and waste.
In particular, state-fostered irrigated farming in the “three norths” has led to degradation or depletion of water, land and forest resources, decimating many aquatic, wildlife and plant species. The 5,830-kilometer Yellow River — the cradle of the Han civilization — was once known as China’s sorrow because of its recurrent flooding. But now it has become a source of sorrow for the opposite reason: With farms and industries siphoning off its waters, it is running dry.
Rapid expansion of intensive irrigation has helped turn China’s semiarid north into the country’s food bowl, although the south boasts fertile land and bounteous water. To sustain this environmentally damaging paradox, the elites, located in the north, have engineered huge water transfers from the south through the Great South-North Water Diversion Project, the world’s largest inter-river and inter-basin transfer program.
More broadly, economic and demographic expansion in Asia is increasingly damaging the environment, while promoting a scramble for limited supplies of commodities.
In per capita terms, Asia is the world’s most resource-poor continent. For example, Asia’s water availability is less than half of the global average of 5,829 cubic meters per person yearly. Thanks to increasing demand for tropical and other timbers, including teak, Asian countries have among the world’s highest deforestation rates. Asia is already the world’s largest importer of fossil fuels, including coal.
Asia’s overexploitation of its natural resources has created an environmental crisis that is contributing to regional climate change. For example, the Tibetan Plateau, which contains the world’s third largest store of ice after the two poles, is warming at almost three times the average global rate, largely because of Chinese policies that have led to intensive mining, giant dam projects, deforestation, elimination of grasslands, and introduction of Western-style agriculture.
Asia’s sharpening competition over commodities is also shaping resource geopolitics, including the construction of oil and gas pipelines. China is sourcing new hydrocarbon supplies from Central Asia and Russia via pipeline. But this option is not available to Asia’s other leading economies — Japan, India and South Korea — as they are not contiguous with suppliers in Central Asia, Iran or Russia.
Natural resources have long played a significant role in global strategic relations, including driving armed interventions and wars. At present, rising dependence on energy imports is being used by Asian powers to build greater naval capabilities, spurring new concerns about sea-lane safety and vulnerability to supply disruptions. One example is the growing tension in the South China Sea, a critical corridor linking the Pacific and Indian oceans.
Meanwhile, Asian challenges emerging from the close nexus between energy, water and food are underlining risks of unprecedented resource-related shocks. Asia is the biggest driver of increased global energy demand, while its food challenges are being compounded by rising incomes that are altering people’s diets, with a greater intake of animal-based proteins. For example, Chinese diets have changed so dramatically since the 1979 advent of economic modernization that China last year reportedly consumed twice as much pork, beef and poultry as the U.S.
Yesterday’s luxuries are becoming today’s necessities, putting greater demand on natural resources — from energy, food and water to metals and minerals — and thereby contributing to environmental degradation. Rising incomes are fueling consumption growth, which in turn is aggravating the environmental impacts.
Declining fertility rates, as in East Asia, are correlated with growing prosperity and greater consumption levels. Rising prosperity fuels resource demand. Changing diets are also an important driver of environmental degradation and resource stress. Humans have changed not only their diet but also the diet of the animals they raise for food: Livestock are often fed grain, not grass, their natural intake.
Because livestock require much more food, land, water and energy than plants, the spiraling Asian demand for meat harms ecosystems and fuels climate change. Meaty diets, in turn, are contributing to an obesity problem. Heavier citizens, with their greater demand on resources, carry a larger ecological footprint.
Simply put, the growing strains on environmental sustainability are tied to factors that extend far beyond population growth.
In fact, as more Asians prosper and seek the everyday comforts of modern life, environmental impacts are likely to be exacerbated in the coming years unless governments adopt a more comprehensive approach to the management of natural resources and to environmental protection. For example, the integration of energy, water and food in national policies is essential to advance synergies.
Asia cannot afford to let environmental issues fall by the wayside. While competition for resources will continue to shape Asia’s security dynamics, the fact is that Asian states cannot sustain their impressive economic growth without addressing their resource, environmental and security challenges in a cooperative framework, including by establishing norms and institutions and pursuing forward-looking policies. Energy, food and water resources must be managed jointly in policy terms.
The New Year should serve as a reminder for governments to adopt more sustainable practices and build healthier and more secure societies through participatory environmental management.
