China National Engineering Research Center for Agro-Ecological Big Data Analysis & Application Desert Locust monitoring and forecasting February 2020 Desert Locust invasion in Africa and Asia Overview Integrated with multi-source Earth Content Observation data, e.g. meteorological data, Overview 1 Migration path and prediction of Desert field data, and remote sensing data (such as Locust in Africa and Asia 1 GF series in China, MODIS and Landsat series Contact us 4 in US, Sentinel series in EU), and tracked. self-developed models and algorithms for Desert Locust monitoring and forecasting, the Migration path and research team constructed the ‘Vegetation prediction of Desert pests and diseases monitoring and forecasting Locust in Africa and Asia Figure1 shows the migration path of the Desert system’, which could regularly release Locust from Year 2018 to 2020. Due to the thematical maps and reports on Desert Locust. influence of Northeast Monsoon and the barrier The Desert Locust has ravaged the Horn of Qinghai-Tibetan Plateau, it has a lower of Africa and Southwest Asia, posing serious probability of the Desert Locust in the threats on agricultural production and food Indo-Pakistan border invading China at present. security of the inflicted regions. The Food and However, if the locust in Pakistan and India Agriculture Organization of the United nations cannot be controlled effectively, and even （FAO）has issued a worldwide Desert Locust disasters erupt, then when the Southwest warning, calling for joint efforts from multiple Monsoon is extremely strong, it may has a countries in prevention and control of the pest higher probability for the locust moving from to ensure food security and regional stability. India to Myanmar via Bangladesh, and higher The migration path of the Desert Locust and risk to invading China's Yunnan and Tibet in make a detailed analysis on the possibility of May to June 2020, according to the analysis. the Desert Locust invasion of China has been 1 Page 2 Figure 1 Migration path of Desert Locust (Year 2018 – 2020) The time series remote sensing monitoring Region, Indo-Pakistan border—southwestern results are shown in Figure2. From October to Baluchistan, shown in Figure3. December 2019, the locust swarms at the At present, a large number of locusts on Indo-Pakistan border began to breed in three the Indo-Pakistan border have spawned on the generations and migrated to spring breeding ground and are about to enter the next round of areas of southern Iran and northern Oman via spring breeding. In addition, desert locusts on Baluchistan. From January to February 2020, the southeast coast of Iran continue to breed locust swarms existed in northwest Pakistan, and invade Pakistan. The scientists warn that, if Nara, Tharparkar, and Cholistan. Some of them the desert locusts in Pakistan are not effectively moved north of Bahawalpur, and some had the controlled in the adult stage in May 2020, the trend of migration to southwest Pakistan and locust plague will continue to outbreak, which southern Iran due to climate impact. may cause a severe blow to Pakistan’s Before May 2020, affected by the agricultural production. In addition, although the Northeast Monsoon, there are three potential Indian locust plague has been controlled to a migration paths of locusts along the certain extent, affected by the southwest Indo-Pakistan border, which are Indo-Pakistan monsoon from May to June, locusts on the border—Bahawalpur—Khyber Pakhtunkhwa, Indo-Pakistan border may migrate from Indo-Pakistan border—Quetta and southern Pakistan to India, continue to invade Nepal, 2 Page 3 Bangladesh, Myanmar, and may a higher risk pests in China, it will bring serious threats to to invade Yunnan and Tibet of China. China’s food security. The scientists suggested Considering China's biodiversity, climate the government to carry out large-scale locust and other conditions are conducive to further disaster monitoring and early warning, while breeding and migration of locusts, coupled with boosting global cooperation on Desert Locust the local Migratory Locust, one of the main prevention to help ensure global food security.
