Climate change presents unprecedented challenges to ecosystems and human communities, necessitating innovative and eco-friendly solutions to bolster resilience. Deeply interconnected with nature-based solutions, indigenous knowledge establishes a synergistic link between traditional wisdom and sustainable environmental practices. Combining insights from generations of indigenous communities deeply rooted in their ecosystems with the regenerative capacities inherent in nature-based solutions, a holistic, effective strategy could emerge to address climate change impacts.The study focuses on an indigenous-nature-based solution for sand mitigation, where wind-transported sand occupies a substantial portion of the region. The arid climate and water policy changes upstream have led to the desiccation of wetlands and increased sandstorms, posing ecological and social challenges. Despite these …

Understanding the effects of windbreaks on aeolian sediment transport rates, and the size distribution of aeolian sediments transported through them, is important for designing windbreaks to optimize their wind erosion mitigation benefits. This field study determines the size distribution of aeolian sediments upwind (x = −100 m), within (x = 100 and 256 m) and downwind (x = 448 and 560 m) (where x is the distance from the first row of windbreak) of a multi‐row Tamarix windbreak as the basis for further investigation of the influence of vegetation on aeolian sediment characteristics. The volumetric percentage of grains around the peaks of 100 and 20–30 µm showed variability with distance and between the three measured events. We found that the vertical distribution of grain size parameters indicated that mean grain size (Mz) may decrease with height upwind of the windbreak, and inflections were observed in the …

This study assesses relationships between meteorological factors and air pollutants with ambient bacterial concentration. In the two main cities of Sistan, Zabol and Zahak, airborne bacteria concentration was monitored using the settle plate method inside and outside household environments during dusty days and nights in summer, autumn, and winter in 2022. As context for the study, it was determined that air quality index (AQI) values >100 on most sampling days in Zabol (51.9%) and Zahak (70.4%), with higher values in summer than autumn and winter. The lowest and highest bacterial concentrations in outdoor air were observed at AQI < 50 (good) and AQI > 300 (hazardous), respectively, in both cities. Bacterial concentration showed a decreasing trend from summer to winter, which coincided with a decreasing trend of air pollutant indices, wind speed, and temperature in addition to an increasing trend of …

Dry playa surfaces can be extremely vulnerable to disturbance which breaks their surface crusts resulting in increased aeolian sand and dust emissions. Trampling by livestock and motor vehicles is an important source of this disturbance. The Hamoun Lakes in the Sistan region of Iran are a major source area of dust storms which are causing damage to infrastructure and communities. This study performed portable wind tunnel tests of controlled surface disturbance by animals (cow, sheep) and motor vehicles (automobile, motorcycle) on a silty playa surface of Hamoun Saberi lake. The aim of this study was to assess the effect of different levels of trampling and disturbed surfaces by both vehicles and livestock on dust emission at wind speeds of 6 and 12 m s−1. A significant increase of sediment emission was found with increased number of passes of vehicles and livestock and the degree of surface disturbance …

Windcatcher is a climatic design element of buildings used for cooling in Sistan of Iran. Siatan has become a dust hotspot, and thus windcatcher should be designed with respect to dust storms for utilizing wind for cooling, on the one hand, and deal with harsh conditions (such as dust particles) on the other hand. In this paper, two identical spaces, consisting of two interconnected rooms (collectively four rooms namely R1, R2, R3, and R4), were examined to assess the dust movement and deposition in the buildings. Rooms R1 and R2 had two windcatchers facing the prevailing wind of the region, and R3 and R4 had windcatchers in the opposite direction of the prevailing wind. Air velocities in the rooms were measured in the centre and adjacent to the left and right sidewalls at heights of 10, 50, 80, 150, 180, and 200 cm. The dust deposition density was measured using 288 samplers which were placed on floors of …

Characterizing airflow and turbulence patterns around real vegetation is essential for predicting aeolian erosion. However, few studies have explored the airflow field around live plants. In this field study, airflow field and turbulence patterns were investigated around a single Tamarix tree. Wind speeds were monitored at 34 locations around the tree at the heights of z/h = 0.13 h, 0.5 h, 1.1 h, and 1.8 h (where h is the height of the tree) in a wind speed of 12.5 m s−1. The results showed that a half-ellipse deceleration zone formed downwind and full-ellipse acceleration zones on the sides of the tree. The largest turbulence intensity was observed at lower heights and in the leeside of the tree where wind speed was highest, and the smallest was found on the sides where wind speed accelerated. On the sides of the tree the structure of wind speed and turbulence profiles was similar and no significant differences (P < 0.001 …

Understanding soil seed banks (SSBs) of Nitraria tangutorum nebkhas is critical for vegetation restoration and ecological management in desert–oasis ecotones. In this study, we conducted a survey in the field and a seed germination experiment in the laboratory to investigate the characteristics of SSB in different sizes and parts of nebkhas and to examine their relationship with aboveground vegetation. The results showed that there were 17 species of plants in six families in the SSB of Nitraria tangutorum nebkhas in a desert–oasis ecotone, dominated by Chenopodiaceae. The life forms were mainly annual herbs, accounting for 58.82%–71.43%. The number of species in the SSB were in the order of large nebkha > medium nebkha > small nebkha, and there was no significant difference in SSB density. However, SSB densities in different parts of each nebkha were in the order bottom > middle > top. The densities were significantly different and showed a decreasing trend as soil depth increased. Most of the plant seeds were distributed in the 0–5 cm soil layer. The similarity coefficient between the SSB of each nebkha and the aboveground vegetation was high. From the bottom to the top, the number of common species and similarity coefficient between the aboveground vegetation and the SSB decreased, and the number of species in the SSB was greater than that of the aboveground vegetation. Vegetation plays a decisive role in the initial development of a nebkha. When the nebkha develops to a certain extent, it reacts to the vegetation, thereby intensifying the differences in the composition of vegetation species in different parts of the nebkha …

Local plants are the most effective elements to control aeolian erosion but their effectiveness requires evaluation. A series of wind tunnel experiments were conducted to monitor the effectiveness of four single shrubs, Nitraria tangutorum, Haloxylon ammodendron, Calligonum mongolicum, and Hedysarum mongolicum, in reducing wind speed and sediment transport. Sediment flux was measured at x/h = 1 (h is the height of plant) and wind speeds were monitored at x/h = -2, −1, 1, 2, 3, and 5 in wind speeds of 6, 8, and 10 m s−1. An area of 1 m2 was scanned with and without plants to obtain bed microtopography change before and after wind application. The results showed that a sheltered zone of 5 h was observed downwind of the plants. N. tangutorum, H. ammodendron, C. mongolicum, and H. mongolicum decreased wind speed by 40%, 25%, 30%, and 40%, and blown sediment about 60%, 40%, 35%, and 30 …

Knowledge of the microclimate and wind regime of different land landscapes can be used to support natural resources development and agricultural productivity in desert areas. The aim of this study is to provide a theoretical basis and technical support for the management of Ulan Buh Desert Oasis and the comprehensive prevention and control of sandstorms from the surrounding desert in northern China. We examined the microclimate and wind regime of three landscapes—desert, desert–oasis ecotone and oasis, and discussed the factors underlying the observed variations. Similar patterns were found in annual temperature, annual relative humidity, and wind speed between the desert, desert–oasis, and the oasis. Compared with the desert and the desert–oasis ecotone, average annual temperature and wind speed in the oasis were lower by 2.56%–5.38% and 32.99%–37.05%, respectively. Average annual relative humidity in the oasis was higher than other areas by 1.31–2.57%. The desert, desert–oasis ecotone, and the oasis were dominated by westerly winds. Wind direction was relatively stable in the oasis and variable in the desert and desert–oasis ecotone. There was intermediate wind energy fields in the desert and the desert–oasis ecotone, and a low wind energy field in the oasis. In the desert–oasis ecotone, drift potential (DP), resultant drift potential (RDP) and resultant drift direction (RDD) were 231.87 VU, 97.21 VU, and 104.33°, respectively. In the desert, DP was 228.45 VU, RDP was 92.65 VU and RDD was 76.05°. In the oasis, the DP was 61.85 VU, RDP was 38.04 VU, and RDD was 92.97°. In the desert and the desert–oasis …

Desert ecosystems are vulnerable to climate change because of their fragile environment and poor self-regulation ability. Exploring the land–surface energy balance and the water/heat transfer processes of such regions for water resource management purposes is critical. The processes of surface water and heat transfer throughout the desert ecosystems and the effects of environmental factors on the energy distribution remain poorly studied. In this study, we used an eddy covariance system and surface meteorological data (2019–2021) to investigate the characteristics of the energy balance of Dengkou Desert ecosystem located in Inner Mongolia, northern China. Also, we evaluated the effects of different environmental factors on the energy distribution in this desert ecosystem. We found that the temporal patterns of both sensible heat flux (H) and latent heat flux (LE) with time are consistent with that of net radiation (R n ), and R n is dominated by H. The sum of the daily average soil heat flux during the observation period was positive, indicating that soil was a heat sink and that the atmosphere transfers heat to the soil. During the observation period, the energy distribution of H/R n fluctuated greatly, presenting a general U-shaped trend, while LE/R n presented an inverted V-shaped trend. The main factor affecting H was R n , followed by saturated vapor pressure, air temperature (T a ), and relative humidity. For LE, the main influencing factors were T a , and R n . The energy closure of the half-hour flux in the Inner Mongolian desert ecosystem during the observation period was 48%–68%, and the energy balance ratio was 0.54–0.74. The …

Dust storms are frequent in the Sistan region of south-eastern Iran and cause a wide range of problems, but few studies have assessed their negative impacts. This paper makes an assessment of the impacts and estimates the damage costs associated with dust storms on transportation systems—aviation, road and rail—over the period 2013–2020. Daily visibility data were used to obtain the number of dust-storm days, and information on the damage to each transportation sector was collected from the relevant local authorities. A strong relationship was observed between dust storms and the number of flight cancellations and car accidents and the amount of accumulated sediment on the roads, by month and year. The impacts were greatest during summer months (June–August) and in 2018, the year of highest dust storm frequency. The total estimated cost to the three transport systems was US$46.5 million over …

Despite many studies describing wind speed and sediment flux profiles in various situations, wind tunnel observations in the presence of live vegetation are infrequent and rarely combined with field measurements. To investigate the structure of wind speed and sediment flux profiles in morphologically different vegetation and various plant densities, wind velocity and sediment flux profiles were obtained over a multi-row windbreak in an arid environment and over unplanted surfaces and canopies of two types of plants in a wind tunnel. Although the two plant types in the wind tunnel have different morphology, the profiles of wind velocity and sediment flux showed structures similar to those for other plant types reported in previous studies which indicates that profile structures are likely common for homogeneous canopies even with different plant morphology and in various wind velocities. The horizontal profiles of …

Sand and dust storms (SDS) are a natural phenomenon dominantly originating in arid and semi-arid regions. The vastness and changing distribution of the SDS hotspots, their inaccessibility, and financial limitations are the greatest challenges to projects combating SDS. To boost project success, a prioritized site-selection method which incorporates the physical and human variables interacting with SDS is applied in this paper. This ensures that potential economic and health impacts of SDS on human populations are also included. Six variables were selected for analysis: within-region sand and dust hotspots, changing distribution of the hotspots, residential areas, vegetation cover, soil texture, and the maximum drought-inundation of the Hamoun wetland. SDS hotspot sites for possible stabilization were identified and prioritized using the multi criteria evaluation (MCE) method. Such prioritization assists the …

Although the effectiveness of windbreaks in reducing wind speed and sediment transport is highly dependent on the efficiency of individual elements, few field studies have evaluated the effectiveness of single plants typical of arid areas such as Tamarix. A series field experiments were conducted in the Niatak area of Sistan to assess the effectiveness of a single Tamarix tree in reducing wind speed and sediment flux. Wind speed was measured on five occasions at 32 positions around the tree and at heights of z/h = 0.13, 0.5, 1.1, and 2 (where h is the height of the tree). Sediment flux was measured over three dust storm events at 15 positions and at heights of z/h = 0.13, 0.5, 1.1, and 1.8. The results showed a reduction of wind speed and sediment flux of 80–90% at x/h = 1, decreasing to about 5–8% at x/h = 12. There was an acceleration of about 12–20% in wind speed and about 25–35% in sediment flux around …

Dust storms cause a wide range of impacts on environment, economy and human health in the Sistan region of southeastern Iran. This paper investigates long-term variability of dust activity over 23 years (1997–2019) using the Dust Storm Index (DSI) and the frequency of dust-storm days (DSD, visibility <1000 m) and assesses the associated importance of various terrestrial and climatic drivers. A dust storm corridor was identified, based on the prevailing wind direction at Zabol, including parts of the Hamoun lakes and surrounding desert in order to study the effects of vegetation cover and lake water levels on dust activity. The results show maximum intensity of dust storms occurred at 10:30 a.m. and in the summer, consistent with the highest wind speeds – associated with the regionally important Levar wind – and highest air temperatures and lowest precipitation and relative humidity.

Windbreaks are barriers that are widely used to reduce wind speed and aeolian erosion. Most windbreak studies have been done in wind tunnels and generally used rigid objects rather than live plants and most of these studies report on the modification of the flow field and not on the effectiveness at reducing sediment transport. A series of experiments were conducted to monitor the effectiveness of a fourteen-rows Tamarix windbreak in the field and in particular to measure the reduction in sediment erosion and transport. Over the course of six dust storm events, with mean wind speed ranging from 9.4 to 18.2 ms− 1, sediment flux and wind speed were measured at seven heights (z/h= 0.05, 0.1, 0.2, 0.4, 0.8, 1.4 and 1.8 where h is the mean height of the windbreak) at five locations upwind (x=− 100 m), within (x= 100 and 256 m) and downwind (x= 448 and 560 m) of the windbreak.

The Sistan region in southeastern Iran is one of the country's main dust storm areas. To reduce the frequency and intensity of dust storms using efficient windbreaks is critical. In a field study the sheltering effect of a multiple-row windbreak (14 rows of Tamarix aphylla) in the Niatak area was evaluated by obtaining the vertical and horizontal values of R c (x, z)(wind reduction coefficient) upwind (x=− 100), within (x= 100 and 256) and downwind (x= 448 and 560) of the windbreak. A slight deflection in the vertical profiles of the sheltering effect at a height of z/h= 0.2–0.8, a significant increase in the R c (x, z) values was observed within the windbreak that demonstrated the roughness influence of vegetation. The sheltering effect increased within the windbreak consistent with the increasing aerodynamic roughness length (z 0). The greatest R c (x, z) values was observed at the beginning of windbreak (x= 100), where the …
