with the rise of climate change and resource scarcity. It is addressed by the agronomists and experts in the field of agriculture in China that as climate changes arise, the daily mean temperatures for rice of all kinds – including that of early rice (produced from March to July), late rice (produced during June to October), and single rice crops (produced during May to October) - are impacted. Due to the challenge of climate change, it has been observed that the daily mean temperatures for rice production over recent years have increased in a range between 0.8 and 4.1 °C. Given this challenge and the rise of climate change, this has altered the planting times of rice production in China. Regarding this challenge, it has been noted that early rice crops and single-crop rice-wheat crops should be planted at a much earlier period than usual, with late rice wheat-crops planting delayed. Given this response, the “predicted net effect would be to prolong the grain-filling period and optimise rice yield”.

the overuse of pesticides also comes from farmers that have a “lack of pest management knowledge, limited accessibility to high-quality governmental agricultural extensions system, misleading information, and the absence of pest prediction and forecast”. Pesticides, in this context, play a role in enhancing crop productivity, ensuring food stability, and to reduce a farmer's loss of income due to pest diseases. Data analysts and researchers have statistically analysed that the “loss of pests and recovery of weed losses by pesticide application worldwide account for one third of the total grain output”. Given the continuous growth of the world population as well as the demand for food safety, the use of pesticides is a crucial element in order to ensure a vast food security stance.

found in Southern China, where the Yangtze River is predominantly situated. China's Yunnan-Guizhou highland consists of more than 10,000 rice landraces, and the three wild rice species (O. Rufipogon, O. Officinalis, and O. Mereriana) commonly exist and is identified as the site of the highest genetic diversity. Over time, these varieties evolved under environmental and cropping conditions into O. Sativa and the subspecies of japonica and indica consumed today. Additionally, as more rice phytoliths are detected in the sites of Hemudu, Diaotonghuan, Xianrendong, and Shangshan – all parts surrounding the Yangtze River, it is these regions that are locations of the geographical domestication origin of wild rice in China.

1169: 360: 1188:, as well as the erosion of the sustainable development of rice production agriculture. The aforementioned consequences serve as a challenge for the overuse of fertilisers where the actions that farmers have taken as a result of an attempt to tackle the challenge of climate change raises concerns on both the overuse of fertilisers and overuse of pesticides which lead to adverse effects on rice-wheat yields and the environment. The overuse of fertilisers and pesticides interchangeably are what the researchers and scientists in the agriculture field of rice production in China have recognised as "inefficient and excessive". 446:

impressions of rice grain in pottery drawn from more than one hundred sites along the 6300-kilometre Yangtze River.” The oldest sample collected comprised a median age of 11,000 years, found upon clustering in the middle of the Yangtze River in the provinces of Hubei and Hunan in central China. In comparison, samples collected from the upstream and downstream regions are ordinarily younger, ranging from 4000 to 10,000 years. Researchers uncovered this pattern, suggesting that rice cultivation originated in the middle of the Yangtze River and has since spread from there.

of the first crop, saving water consumption by taking advantage of the remaining water content from the first crop. From the latter, rice ratooning increases farmers’ profitability with sustainable efficiency and fewer reconstruction efforts on environmental damage and footprints than other rice planting methods. In addition, rice ratooning provides higher grain yield stemming from selecting cultivated high-yielding varieties and improving crop management over time. Hence, rice ratooning gradually became favourable and forms the majority of the rice production system across China.

1119: 1025: 1085:, fertilisation, and water resources also affect rice quality. This is because the methods used have variances in temperature and light resources during the final stage of rice growth. Moreover, researchers in the China National Rice Research Institute conducted studies in rice fields and have found that an increase in potassium fertiliser used to improve root growth, plant vigour, lodging prevention, and enhance crop resistance to pests could reduce the chalkiness and improves rice quality, but have adverse effects on human consumption. 1152:

across China, and demand for rice is predicted to increase by approximately 20% by 2030. Even so, because of rice yield stagnation that agronomists and scientists have observed during recent years, there have been limits in the capability to increase rice yields with the expectation that this is to continue into the near future. The challenge that has been causing this stagnation has been “attributed to reaching the biological yield ceiling for rice in which many studies have reported that climate change affects rice production”.

pesticides used “per unit area in China is 2.5 to 5 times higher than developed countries”. Inasmuch as the overuse of pesticides has provided benefits in terms of agricultural profitability, the overuse of pesticides can pose a number of risks and challenges to “human beings, animals, and the environment”. The risk and challenge of overuse of pesticides on the environment leads to the issue of sustainable land management that has arisen from the overuse of pesticides as the chemicals can “contaminate masses of soil, water,

October and November. All three crop types contribute about 34 percent to China's total rice output. Double-crop late rice, planted after the early crop is reaped, is harvested in October to November and adds about 25 percent to total rice production. Rice grown in the north is planted from April to June and harvested from September to October and it contributes about 7 percent to total production. As the climate becomes warmer, it becomes possible for rice cultivation to advance further north.

The convenience of direct seeding and mechanical transplanting method can be manifested in the rice planting area of the Jiangsu Province in China, which comprises 2.249 million hectares of land, encapsulating 55.9% of fields that use these methods interchangeably.

Moreover, the excessive use of chemical pesticides that kill both natural pest enemies and beneficial pests in rice-wheat crop production leads to the evolution of resistance to crop pests. In addition, the overuse of pesticides also contributes to the adverse effects that impair human health, in which humans are exposed to the pesticides and pesticide residues present in foods that contain rice and rice-grain related crops. 1197: 1217:, and other vegetation”. It has been identified by the agricultural researchers in China that each year, more than 10 million mu, that is, a measure used for land area in China, of crops are contaminated by the overuse of pesticides and residues. In addition, it is reiterated by these researchers that only 30% of applied pesticides are used up on rice and wheat crops, with the remaining 70% of pesticides used dispersed into the mass environment. 28: 1293: 317: 4021: 1467:, that is, the outer layer of the rice grain that is removed by polishing the rice in order for it to turn from brown rice to become white rice.
