Abstract: Locust plagues are natural
disasters caused by the large-scale occurrence and migration of locusts. Locust
occurrence can be transnational and transcontinental; therefore, one of the
basic tasks for global locust control is to understand its large-scale spatial
and temporal characteristics. In this study, we extracted the temporal and
spatial information of locusts in the northern hemisphere from multiple
resources, including international English articles, historical documents, and
the ??Chinese Meteorological Records of the Third Millennium,?? and estimated
areas of locust occurrence over a period of time. The kernel density method was
used to obtain a dataset that included nine periods of locust disaster distribution
in the northern hemisphere: before 1000, 1000–1200, 1200–1300, 1300–1500,
1500–1700, 1700–1850, 1850–1900, 1900–1950, and 1950–2000. The data were in
Equal Earth projections, with a spatial resolution of 100 km. The dataset was archived
in .tif format and consisted of 18 data files with a size of 43.8 KB.

1 Introduction
A locust plague is
a disaster caused by locusts, insects of the order Orthoptera, family
Locustidae. Locusts are widely distributed??in tropical and temperate grasslands
and deserts worldwide. Under certain conditions, locust populations explode and
migrate widely, eating crops and grassland vegetation, causing severe economic
losses and famine. One of the main locust species that causes locust plagues in
China and around the world is the migratory locust (Locusta migratoria),
belonging to the subfamily Acridoidea (Oedipodinae)[1,2]. Another locust
species that frequently causes locust plagues is the desert locust (Schistocerca gregaria), which is found
mainly in Africa and throughout western Asia and extends to parts of southern
Asia[3,4]. In North America, locust plagues are mainly caused by the
Rocky Mountain locust (Melanoplus spretus)
and the high plains grasshopper (Dissosteira
longipennis) [5,6].
The locust plague is a worldwide disaster.
In early human history, locust plagues have been documented in Egypt, Hebrew,
ancient Greece, and China. The Exodus and Revelation chapters of the Bible classified locust plagues as a major disaster. In 2020, desert
locust plagues hit many parts of the world, from Africa to South Asia, with a
massive infestation in East Africa that devastated hundreds of thousands of
acres of farmland and reduced food production in India by 30%–50%. In 2003,
locust outbreaks in the western U.S. states of Nevada, Utah, and Idaho caused
large economic losses. Historically, locusts have caused one of the three major
agricultural disasters in China, along with droughts and floods. Since ancient
times, locust plagues in China have been widely documented, mostly in the
Hebei, Henan, and Shandong provinces[7]. From 1856 to 1858, locusts
plagued Guangdong, Jiangxi, Hunan, Tibet, and the north area of China. The Qing
Shilu records that ??the locusts covered the sky, blocking the windows and
piling up the doors, leaving no gaps in the rooms?? and that ??the locusts ate
all the seedlings, and large numbers of people died.??.
The occurrence of locust plagues is related
to many factors, such as locust characteristics, climate, and human activities.
Therefore, the prevention and control of locust plagues face significant
challenges. Understanding the spatial and temporal characteristics of locust
occurrence through its historical distribution is an important basic task for
analyzing the factors of locust occurrence. At present, although scholars in
China have done a lot of work on the historical dynamics of locust occurrence[7,8],
these studies are often limited to textual descriptions or time series only[9–11].
Concurrently, the literature and data from other countries are fragmented and
lack systematic organization. Moreover, locusts, as a global disaster, can
occur across countries and continents, and local data do not reflect the full
distribution characteristics. Therefore, a large-scale spatial and temporal
distribution dataset of locust occurrence is important and must be developed.
2 Metadata of the Dataset
A summary of the
full name, authors, geographic region, year, temporal resolution, spatial
resolution, dataset composition, data publication and sharing service, and data
sharing policy of the 100-km raster dataset of locust plagues for nine historical
periods in the northern hemisphere[12] is shown in Table 1.
3 Methods
3.1 Data Sources
Because this study
aimed to respond to the spatial distribution of locust occurrence in the northern
hemisphere, this dataset was developed by obtaining geographic information on
locust occurrence from domestic and foreign historical documents and then
mapping the spatial distribution in different time periods in the northern
hemisphere. The data sources were divided into domestic and foreign. China has
a wealth of historical documents with recorded locust plagues. In this study,
the locust data in the Chinese region were mainly extracted from the Chinese
Meteorological Records of the Third Millennium[14,15]. The foreign
data was mainly searched by Google Scholar, including relevant journal articles
and publications (Table 2). The English keywords used included locust plague,
locust outbreak, locust swarming, and locust disaster. More than 9,500 records
were collected both at home and abroad.
3.2 Locust Historical

distribution
of locust occurrence at different times over the millennium. The latitude and
longitude of locust occurrences were obtained by matching contemporary location
information with historical records. Locust occurrence is often regional and
migratory, and there are gaps in locust occurrence records worldwide. To
analyze the overall variation of locust occurrence areas over a long time
scale, this dataset estimated the locust occurrence areas according to the
kernel density range estimation method for a certain time period (e.g.,
1000–1200 A.D.). We then censored the locust occurrence areas with a resolution
of 100??100 km (Equal Earth projection). The time intervals were before 1000,
1000–1200, 1200–1300, 1300–1500, 1500–1700, 1700–1850, 1850–1900, 1900–1950,
and 1950–2000. Equal Earth and WGS-84 projections were used to build the
dataset.
4 Data Results and Validation
In
terms of the historical spatial distribution of locust occurrence, locusts in
the northern hemisphere were mainly concentrated in the mid-latitudes in the
last millennium, consistent with the suitable distribution area of locusts. In
terms of longitude, locust records were mainly concentrated in Europe, Africa,
and China (Figure 1, 2). In terms of time, locust records were mainly concentrated
between 1400 A.D. and 1900 A.D. (Figure 2). The locust plague records in China
were the most complete in the last millennium, especially in the Ming and Qing
dynasties.

locust plagues in latitude, longitude, and time

in the northern hemisphere over the past millennium (Equal Earth projection)
5 Conclusion
The
historical records of locust occurrence and distribution may be more closely
related to the state of national social development and the history of written
records. Specifically, locust occurrences in Europe and the United States
rarely became plagues after 1990 and in China after 1950, and records decreased
significantly, whereas, Africa, the United States, and South Asia had more
records only after 1700. Data from Central Asia may have been less recorded
because of the lack of written records or geographic reasons. Overall,
historically, China has been the most affected in terms of locust occurrence,
which is consistent with its status as a historically large agricultural
country. Similarly, locust plagues were more severe in North America during the
locust agricultural development period. Notably, locust infestations in China
and North America have been controlled extremely effectively owing to
scientific and rational control measures.
