Laser-controlled land leveling (LLL) can help improve rice production's spatial and temporal management, leading to optimized water and crop management. This research resulted in sustainable performance indicators to illustrate that LLL is a sustainable technology for rice production. The assessment was conducted in Cambodia, the Philippines, Thailand, Vietnam, and India. Benefits of LLL include saving land use, water, and agronomic inputs, increasing yield, and decreasing postharvest losses resulting in saving energy of 3.0–6.9 GJ ha⁻¹ and decreasing emissions by 1151–1486 kg CO₂-eq ha⁻¹. Additionally, LLL application can obtain a net profit of USD 52–84 ha⁻¹ per rice production season in the countries studied. The result demonstrated that LLL is a sustainable technology as well as strongly supports sustainable rice production. The study would lead to better adoption of this technology through its evidence-based promotion.

激光控制的土地平整 (LLL) 可以帮助改善水稻生产的空间和时间管理，从而优化水和作物管理。这项研究产生了可持续的绩效指标，以说明 LLL 是一种可持续的水稻生产技术。评估在柬埔寨、菲律宾、泰国、越南和印度进行。LLL 的好处包括节省土地使用、水和农艺投入、增加产量和减少收获后损失，从而节省 3.0-6.9 GJ ha ^-1的能源并减少 1151-1486 kg CO ₂ -eq ha ^-1的排放。此外，LLL 申请可以获得 52-84 美元的净利润^-1研究国家的每个水稻生产季节。结果表明，LLL 是一种可持续技术，并强烈支持可持续水稻生产。该研究将通过基于证据的推广来更好地采用这项技术。
