The Impact

Dust storms are frequent in Australia and can have a large impact on the soil resource, the economy and people. There have been few economic studies of the impact of wind erosion worldwide and only one in Australia before this study. While wind erosion impacts on the soil resource at the point of the erosion, the level of economic impact rises as the population and associated infrastructure affected by dust increases. This study estimates the impact on the economy of the state of New South Wales of a single large dust storm called Red Dawn that passed over the eastern coast of Australia on 23 September 2009. Estimates for rural and urban areas are presented with both on- and off-site costs evaluated. The estimated cost is A$299 million (with a range of A$293–A$313 million) with most of the cost being associated with household cleaning and associated activities. The dust storm also impacted on many cities on the coast of the state of Queensland, but their costs are not included in this study. This study demonstrates some, but not all, of the major economic costs associated with wind erosion in Australia. Given the annual average cost of dust storms it is suggested that A$9 million per year would be a conservative estimate of the level of investment required in rural areas for dust mitigation strategies, based on improved land management that could be justified to achieve a positive impact on soil condition and reduce economic losses in rural towns and the more populous coastal cities.

The description of the typical structure of agricultural landscapes of Ukraine and the most common degradation processes are given. Water and wind erosion are considered as one of the largest contributors to soil degradation in Ukraine, accompanied by declining soil fertility, moisture loss to surface runoff, air and surface water pollution, and degradation of small rivers. The sown areas of main crops for 1990–2020 are analysed per administrative oblast according to the State Statistical Service of Ukraine. A global long-term satellite remote sensing land surface temperature dataset (NOAA AVHRR) was used to analyse the dynamics of the average sum of effective temperatures for the vegetation season in 1982–2019. Sentinel-5P satellite data was used to analyse the spread and exposure of a large-scale dust storm in Polissya region in April 2020. As a result of climate change and economic factors, the area under corn and sunflower has been significantly increased. Due to the increased frequency of stormy rains and strong wind under climate change, the conditions for intensification of water and wind erosion in agricultural landscapes has been created. The local manifestation of wind erosion is typical for Polissya, mainly on overdried peat bogs and cohesive-sandy soils. But in the spring of 2020 a large-scale dust storm was observed for the first time on the territory of Ukrainian and Belarusian Polissya on the area of about 3.5 million hectares.The growing risk of soil erosion due to the climate change and current agricultural practices requires the improvement not only of the state land management system, but also the agri-environmental monitoring system, scientific methodical and information-advisory support of regional governments, landowners and land users. In order to implement state policy and coordinate the work on the rational use and protection of soils, combating their desertification and degradation, as well as adaptation of land use systems to climate change, it is proposed to establish the governing body «Monitoring, land management and soil protection» on the basis of existing specialized units of central and regional governments in the Ministry of Agrarian Policy and Food of Ukraine.

Climatic Elements

The dust storms and their recurrence are common phenomena in Iraq because it suffers from the exploitation of mankind to the natural environment and to the deterioration of vegetation and soil which responsible to the exposure of the soil to wind erosion leading to dust phenomena. Rain is one of the most influential climatic elements in reducing and minimizing the impact of dust storms. The amount of rainfall in Iraq is relatively small, where most of the year is not rainy. This in turn increases the dryness of the soil and increases the formation of dust storms. In this research data of (visibility, wind speed and direction and total rain amount) from the Iraqi Meteorological Organization and Seismology were analyzed for nine stations spread across the country (Mosul, Kirkuk, Haditha, Baghdad, Rutba, Nukhayb, Najaf, Amara and Nasiriya) for the period from 2001 - 2017 to compare annually severe dust storms with rainy seasons. Drought seasons were also determined using the percent of normal rainfall (PN) method. It was found that there was an inverse relationship between rainfall and severe dust storms, (according to Pearson’s correlation coefficient) where it was noticed that the highest amount of rainfall was in Mosul station with a total of 5231.6mm during the study period with only 6 severe dust storms during the same period. In other hand the lowest amount of rainfall was in Nukhayb station 1304.6mm during the study period with 62 severe dust storms.

Asian Dust Storms

A coupled modeling system has been developed to describe the mineral dust cycle in the atmosphere. It is composed of MM5, ECIP, WE (wind erosion model) and CMAQ. A strong dust storm of North China in 2002 is simulated by this system. The modeled results show good consistent with observations and pre-existing researches in aspects of dust emission flux in source regions, distributions , vertical profiles and time variation of dust aerosol. Therefore, it can be used for further study on Asian dust storms. Furthermore, this system can be developed for further studies of the impact of dust aerosols on air quality.
