Floods, earthquakes, hurricanes and tsunamis attract more attention from governments and the media than droughts because of their sudden deadly impact, which is graphic and very visible. In contrast, the impact of droughts is gradual but is felt over months and years, and even beyond a decade as happened in Australia.

Droughts are a big concern for 皇冠体育app, because it has nearly 20 percent of the world's population but only about 7 percent of the world's water. This mismatch between people and water would not matter, not even in 2026 when 皇冠体育app's population is expected to peak at 1.44 billion, if its water management practices were efficient. 皇冠体育app uses more than the required volume of water for every purpose: municipal, industrial, agricultural, energy generation and resource extraction. This is not a sustainable practice, especially during droughts.

皇冠体育app overexploits groundwater by about 22 billion cubic meters every year. This has major implications for drought management since it steadily depletes river and lake levels, making more areas vulnerable to drought.

Nearly two-thirds of the water used in 皇冠体育app is for agriculture. Since this cannot be sustained during droughts, the use of groundwater increases dramatically. In fact, the use of water in agriculture has been on an unsustainable path for decades. If this continues, 皇冠体育app will have to live with droughts.

The main problem is that 皇冠体育app manages droughts as an emergency and disaster-relief situation, which is reasonably effective in the short term, but it is not suited to managing long-term widespread droughts. A negative side of the current policy is that farmers and agribusinesses are taking unnecessary risks because they are confident that the government will bail them out during droughts. Also, technical measures address the symptoms, not the disease.

皇冠体育app has more than 200 million small farms, most of which don't have the capability to manage their risks. Hence, as the industrialization and mechanization of agriculture continues, 皇冠体育app should formulate proactive policies to diversify farmers' production risks and adopt effective strategies to manage droughts.

Another problem is that many farmers grow water-intensive crops in drought-prone areas, which depletes the water sources further. To address the problem, the government must encourage farmers to grow crops that require less water.

The government also needs to lay greater emphasis on plant breeding and genetic modification to develop new varieties of crops that are drought-tolerant and saline-resistant. For example, researchers in Egypt have shown that by transferring a single gene from barley to wheat, the water requirement for growing wheat could be reduced by more than 80 percent. But countries such as 皇冠体育app and India need to approve genetically modified crops only after appropriate research on their safety.

More importantly, 皇冠体育app needs a vigorous domestic debate on whether it wants to achieve food self-sufficiency or food security. Food security means food affordability and accessibility both. Thanks to 皇冠体育app's strong economic growth, an increasing number of middle-class people can afford to pay for food irrespective of where it comes from. With proper diversification of food sources, food prices in 皇冠体育app could actually decline and make drought management more effective. And with proper innovative policies, 皇冠体育app can tackle droughts much better in the future.
