A news that shocked the whole country spread quickly on social media: "China's rice cultivation exacerbates the global greenhouse effect!" This shocking accusation from the Western media is like a bolt from the blue, leaving countless Chinese in confusion.
In the face of this sudden storm of public opinion, agricultural experts frowned and fell into deep thought.
Let's lift the veil on this controversy and delve into the intricate relationship between rice cultivation and climate change. In the process, we may be able to find a smart way to balance food security and environmental protection.
Standing on the edge of lush rice paddies, it's hard to imagine that this land of life has become the focus of environmental controversy. However, the relationship between rice cultivation and climate change is far more complex than we think.
According to the study "Speaking with Data: How Rice Farming Can Better Sequester Carbon and Reduce Emissions", rice production does produce greenhouse gases. When we step into the rice paddies, a microcosm of the chemical reaction is unfolding in the soil beneath our feet.
Organic matter in the soil is constantly decomposed by microorganisms, releasing greenhouse gases such as carbon dioxide, methane and nitrous oxide. This process is like nature's breathing, seemingly ordinary but has a profound impact on the global climate.
But that's only half the story. When the sun shines on the rice leaves, another wonderful process is quietly taking place. Through photosynthesis, rice is greedily absorbing carbon dioxide from the atmosphere, converting it into organic carbon, which is stored in stems and leaves.
This process is like nature's air purifier, silently cleaning the atmosphere for us.
An agricultural expert explained: "We need to look not only at the greenhouse gas emissions of rice production, but also at its carbon sequestration role. The true impact should be net carbon emissions, which is the difference between emissions and carbon sequestration.
This perspective gives us a more comprehensive understanding of rice cultivation. It is neither a mere environmental killer nor a perfect carbon sink. The truth is often hidden under the surface of controversy, which requires us to explore it with a scientific attitude.
In fact, greenhouse gas emissions from rice production are influenced by a variety of factors. Farming practices such as water management, straw treatment, and nitrogen fertilizer use all have a direct impact on the amount of greenhouse gases produced.
This means that by optimizing cultivation techniques, it is possible to reduce greenhouse gas emissions while maintaining food production.
On the other hand, the carbon sequestration capacity of rice cannot be ignored. During the growing season, rice absorbs a large amount of carbon dioxide through photosynthesis, which is partly converted into organic matter and stored in plants, and partly enters the soil through root exudates to increase soil organic matter content.
This process not only fixes carbon in the atmosphere, but also improves soil fertility, killing two birds with one stone.
Therefore, the impact of rice cultivation on the climate is a complex balancing act. We need to consider its greenhouse gas emissions and carbon sequestration in a holistic manner, and scientifically assess its net impact, rather than simply labelling it as an "environmental killer".
Only in this way can we find a sustainable development path that guarantees food security and protects the environment.
In the face of accusations from the Western media, Chinese agricultural scientists did not sit idly by. Instead, they have quietly launched a green revolution to reduce environmental impact while ensuring food security.
Step into China's rice paddies and you'll find a very different scene than usual. An elderly farmer explains with a smile: "We are now using intermittent irrigation, and instead of soaking the fields all day long.
"This new approach not only saves valuable water resources, but also reduces methane production. When we leaned over to observe the straw in the field, the farmer continued: "We no longer burn these straws, but return them to the field."
These innovative agricultural practices did not come out of nowhere, but were derived from an in-depth study of the "Accounting for Greenhouse Gas Emissions in China's Agricultural System in the Past 40 Years". Studies have shown that methane and nitrous oxide emissions can be significantly reduced by adjusting water management, straw returning and optimizing nitrogen fertilizer use.
These seemingly simple changes have opened up a new path for the sustainable development of rice cultivation in China.
But China's innovation doesn't stop there. When we mention "hybrid rice", the eyes of farmers sparkle with pride. "This is our 'super rice'!" He said excitedly.
The development of hybrid rice technology can be called a revolution in China's agriculture. Under the leadership of Academician Yuan Longping, the research team successfully developed three generations of hybrid rice, which not only greatly increased yield, but also indirectly reduced greenhouse gas emissions.
The significance of this technology goes far beyond increasing yields.
A staggering set of data is in front of us: the spread of hybrid rice technology can save about 1 arable land per year. 500 million mu is equivalent to reducing a large amount of land development demand.
At the same time, it also saves 30 billion cubic meters of water resources, reduces the use of chemical fertilizers by 10 million tons, and reduces the use of pesticides by 5 million tons. These reductions not only reduce production costs, but more importantly, reduce greenhouse gas emissions1. An astonishing result of 500 million tons.
These achievements make people sigh that China is not only trying to feed its own people, but also contributing to global climate change with concrete actions. By continuously innovating and optimizing cultivation techniques, China is exploring a sustainable path that ensures food security while reducing environmental impact.
However, China's agricultural scientists did not stop there. They are well aware that there is still a long way to go in the face of the growing challenge of climate change. They are actively exploring more innovative technologies, such as developing new varieties that are resistant to drought and salt, researching more precise fertilization techniques, and using artificial intelligence to optimize rice planting management.
This green revolution is not only for the sake of the Western media's skepticism, but also for the sustainable future of China and all mankind. Through unremitting efforts and innovation, China is showing the world how to strike a balance between ensuring food security and protecting the environment.
This is not only China's contribution, but also provides valuable experience and wisdom for the global response to climate change.
As we expand our gaze from China to the whole of Asia, a broader picture emerges. India, Indonesia, Bangladesh, Viet Nam, Thailand...... These countries are also the world's most important producers and exporters of rice.
When we visit the rice fields of these countries, we are surprised to find that their rice cultivation methods are strikingly similar to those of China. The same green rice fields, the same flooded way of planting.
A farmer from Viet Nam told us: "We have been growing rice this way for generations, and this is the wisdom left by our ancestors.
Yet this similarity raises a troubling question: Why do the Western media only blame China's rice cultivation while turning a blind eye to the same practices in other countries? This selective criticism clearly lacks fairness and objectivity.
"The impact of rice cultivation on global climate change is a complex issue that needs to be confronted and addressed by all countries involved," an international agricultural expert said.
It was unfair to blame a single country and would not help solve the problem.
Such double standards are not only detrimental to the solution of the problem, but may also lead to misunderstandings and contradictions among the international community. At an agricultural conference in India, a local expert angrily said: "If rice cultivation is really so harmful, why is only China criticized?" All of our rice-producing countries should be treated fairly.
In fact, all of Asia's largest rice countries face a similar challenge: how to reduce environmental impact while maintaining food security. Many of them are also actively exploring greener cultivation methods.
For example, Thailand is promoting intermittent irrigation technology, while India is experimenting with direct rice technology to reduce greenhouse gas emissions.
These common challenges and efforts underscore the importance of international cooperation. What we need is fairness, objectivity and collaboration among countries.
Only by working together to share experience and technology can we truly address the challenge of global climate change while ensuring world food security.
In the face of this global problem, we should put aside our prejudices and work together to find solutions. After all, whether it is China, India or any other country's rice fields, they are the common breadbasket of mankind and our common home.
At this juncture, we are faced with an unprecedented challenge: how to effectively respond to climate change while ensuring food security. It is a complex and arduous task, but the eyes of Chinese agricultural experts shine with determination and hope.
"We must not give up or deny rice cultivation because of the accusations of the Western media." "Instead, we will continue to innovate and upgrade rice cultivation technology to improve production efficiency and quality, while striving to reduce environmental impact," said a senior agricultural scientist.
This is our responsibility and our opportunity.
The road ahead is challenging, but it also holds endless possibilities. We can expect that in the near future, more intelligent and environmentally friendly rice cultivation techniques will emerge.
Perhaps one day our rice fields will not only produce food, but also become the "green lungs" of the planet and make a greater contribution to the fight against climate change.
A young agricultural engineer is developing a new type of precision irrigation system. "The system automatically adjusts the amount of irrigation based on soil moisture and crop demand, which not only saves water but also reduces methane emissions," she enthuses.
Another team is studying how biochar technology can be used to improve soil carbon sequestration, which could open up a new way to reduce emissions in rice cultivation.
However, China alone will not be enough to address this global challenge. We call on the international community to work together to address the challenges posed by climate change.
An expert from the International Agricultural Organization said: "Climate change is a common threat for all humanity and requires all countries to share responsibility. Only by putting aside bias and strengthening cooperation can we find a balance between ensuring food security and protecting the environment.
Looking ahead, we look forward to seeing more international cooperation projects, such as joint research and development of drought-tolerant varieties, sharing water-saving technologies, and establishing a global agricultural greenhouse gas monitoring network.
These efforts will not only promote advances in agricultural technology, but also promote understanding and trust among countries.
In the face of the dual challenges of food security and environmental protection, what we need is not only technological innovation, but also a change in thinking. We must be more open and inclusive in our global approach to finding solutions.
Only in this way can we create a sustainable future for future generations that is both fed, clothed, and environmentally friendly.
When we gaze at the rice grains in the bowl again, we may have a different perception. These small white particles carry far more profound meanings than we can imagine.
They are not only the staple food of the Chinese, but also the common wealth of all mankind and a symbol of hope for the future.
In the face of the severe challenge of climate change, we need to continue to explore with a scientific and rational attitude, and contribute China's wisdom to global environmental protection while ensuring food security.
Let's work together to create a sustainable future where rice paddies become not only the breadbasket for humanity, but also a green shield for the planet.
In this great journey of human well-being, every grain of rice is our commitment to the future, and every rice field is our affectionate protection of the earth.
