Pests and diseases cause significant losses of crops around the world and is a significant threat to food security. In China the migratory locust affects over 2 million hectares of agricultural land, while in Laos the yellow spined bamboo locust which is widespread across the 9 districts of Norther Laos and damaged over 5,000 hectares of crops in 2019. A new invasive pest, the Fall Army Worm is becoming prevalent in Southeast Asia and China. It has been found in 22 provinces in China and affected 35,000 hectares of maize in Laos. Experience from Africa shows it can cause almost total crop losses. Managing the damage from pests can be difficult due to lack of detailed information on where risks to crops are greatest, use of inappropriate or ineffective control measures, and build of resistance in pest populations to chemical pesticides. In addition overuse of chemical pesticides causes environmental damage in the form of loss of biodiversity and through chemical residues left in the environment, particularly in waterways. In this project we will use Earth observation and meteorological data to provide information that will help farmers and agricultural authorities manage pest risk more sustainably. Using Earth observation imagery we will prepare risk maps that identify habitats where locusts and fall armyworm are most likely to establish populations. Using satellite data on surface temperature we will develop and run models that predict i) the growth of insect populations and ii) the effectiveness of biological control methods. The models will provide information to help preparedness and to guide the timing of application of biopesticides. The project will build upon work already undertaken in North-East China and apply it in the Southern Chinese province of Hainan, and in Laos. We will provide risk base maps and information products that help chose the method and timing of interventions. We will work with agricultural management authorities in China and Laos, providing training in the use of the information.

害虫和疾病在世界范围内造成了巨大的农作物损失，对粮食安全构成了重大威胁。在中国，迁徙的蝗虫影响了200万公顷的农业土地，而在老挝，黄色的竹蝗虫在诺瑟尔老挝的9个地区广泛，2019年损害了5,000多公顷的农作物。一种新的入侵pest，秋天的军队在东南亚和中国逐渐普遍存在。它在中国的22个省发现了它，并影响了老挝的35,000公顷玉米。来自非洲的经验表明，这几乎会造成全部作物损失。由于缺乏关于农作物风险最大，使用不适当或无效的控制措施的详细信息以及在害虫种群中建立对化学农药的耐药性，因此很难管理害虫的损害。此外，过度使用化学农药会以生物多样性的丧失以及环境中留下的化学残留物的形式造成环境破坏，尤其是在水道中。在这个项目中，我们将使用地球观察和气象数据来提供信息，以帮助农民和农业当局更可持续地管理害虫风险。使用地球观察图像，我们将准备风险图，以识别蝗虫和堕落的军虫最有可能建立种群的栖息地。使用卫星数据在表面温度上，我们将开发和运行模型，以预测i）昆虫种群的生长； ii）生物控制方法的有效性。这些模型将提供信息，以帮助准备并指导生物农药的应用时间。该项目将基于已经在中国东北部从事的工作，并在中国南部海南省和老挝应用。我们将提供风险基本图和信息产品，以帮助选择干预措施的方法和时机。我们将与中国和老挝的农业管理当局合作，提供信息的使用培训。
