The Status of Land Degradation Induced by Soil Erosion and Management Options in Duna District, Hadiya Zone, Central Ethiopia

Land resource degradation is a significant environmental issue that adversely impacts economic development and the livelihoods of farming communities. Therefore, the study aimed to explore land degradation by soil erosion and its management options in study area. To evaluate the causes and status of land degradation and for explore management practices against land degradation in the research area. To meet the established objectives, relevant data was gathered from samples area which was chosen using a stratified sampling method based on their agro-ecological conditions. The study's findings show that the livelihoods of all sampled household heads rely on mixed farming activities, with 90.3% of respondents engaged in both crop production and livestock rearing. The study indicates that crop and livestock productivity among household heads has been declining over time due to land degradation. In addition to land degradation, land shortage and limited access to farm inputs are significant challenges for crop production, leading to the expansion of farmland into grazing areas to compensate for crop losses caused by land degradation. The extent of land degradation in the study area continues to increase over time, as indicated by findings from the four selected kebeles are highly degraded; High population pressure, the area's topography, and frequent changes in farming and land use are the primary factors exacerbating land degradation in the study area, leading to a decline in the quality of farmland productivity. In response to the impacts of land degradation on their livelihoods, the community has implemented various strategies. Common approaches in the study area include cultivating cereal crops, engaging in daily labor, practicing handcrafts, planting perennial crops like buckthorn for sale, participating in irrigation activities, and clearing vegetation and forests to expand farmland.

Review of Slum Management Policies in Urban Areas

Urban slum areas in Indonesia began to feel very disruptive to city mechanisms and dynamics in the late 70s, so the government launched Village Improvement programs such as the Moh Slum Improvement Program. Husni Thamrin in Jakarta, Dewi Sartika Village Improvement Program in Bandung, and other village improvements carried out in big cities in Indonesia. While these programs have not been able to solve existing problems, city dynamics are running so fast, especially after reform. The development of cities with very high population pressure is beyond the government's ability to control them. On the other hand, the need for employment and business is very large due to the financial crisis and the phenomenon of job cuts (PHK), because many companies are going bankrupt. This problem must be borne by the city ecosystem which has many limitations. People in every city, because they are pressured by the necessities of life, can do business in urban areas wherever they think there is a chance to live. In this situation, the growth of slum areas in urban areas not only occurs in residential areas, but also occurs in business areas and along road routes which are still possible to use as places of business and residence. Of course, this cannot be tolerated, and the government needs to respond through appropriate policies now and in the future, considering that slum areas are now evenly distributed to all cities in Indonesia and not only in big cities.

Enhancing Chinese Pension Funds Development through ESG Investment Perspectives

In current China, where the pension funds system is facing enormous pressure, this article will explore the positive impact of incorporating ESG investments into the Chinese pension funds system on its future development. Through research on the current situation of China's pension system, it is found that there are problems such as uneven regional distribution, unbalanced development of the three pillars, high population pressure and funding gap, high investment return requirements, and limited investment channels. By studying the feasible experiences of top ESG investment companies and leading countries in development, it is concluded that ESG investment contributes to improving the return on investment and stability of pension funds, and can alleviate the existing problems in China's pension funds. Finally, it is summarized that the feasible experience of combining ESG investment with China's pension funds is to take the lead in policies first, combined with strict supervision, and pay attention to talent cultivation.

Application of Game Theory in Solving Urban Water Challenges in Ibadan-North Local Government Area, Oyo State, Nigeria

The significance of water in human life cannot be ignored, but in most of the developing countries; availability, provision and access to good water source to the citizens has post major challenges. The nature of water scarcity has been majorly attributed to seasonal factor and high population pressure. This study therefore aimed at developing a practical approach and mechanism to solving water challenges in urban areas in Nigeria by means of game theory. The findings revealed that majority of respondents lack access to portable or drinkable water from water agency and that regular water supply sources have been traced to be borehole or well which was provided by citizens in the community at a cost. Applying the game theory approach, the outcome of the game indicates that the equilibrium value for the two players (the water agency and the residents) is N2,000 for 1,000 liters of water supply monthly. However, the payoff can be maiximised by every player (monetary values for the water agency and satisfactory water consumption for the residents). It is therefore importance that water agency should improve in the quality of their work in providing adequate water supply to the community to reduce or eradicate ailment arises from non availability of quality water.

Intercropping Options for Sustainable Minor Millet Production: A Review

High population pressure, climate change, stagnant crop productivity, changing food habit and declining natural resources compelled us to go for climate resilient resource conservation technologies to bring sustainability in our crop production. Crop diversification by replacing high input requiring cereals with “nutri- cereals” minor millets in our crop rotations and by following intercropping of minor millets with pulses or oilseeds may be economically profitable, environmentally safe and socially acceptable approach to ensure food and nutritional security of the burgeoning population. This is high time to include millets in our daily diets but millet availability in sufficient amount is big issue. Millets are crops of rainfed and dryland resource poor areas and moreover under the threat of global warming and changed climatic scenario sole planting of millets generally gives less economic returns. So, there is an urgent need for incorporation of the pulses/oilseeds as intercrop in millets production system to enhance the production to feed the increasing population on sustained basis besides restoring the soil nutritional status and to overcome the environmental stress. But performance of intercropping system depends on proper selections of suitable intercrop, appropriate row ratio combination and proper input management. Very limited research work has been conducted on intercropping in millets so far but noteworthy information was recorded by the researchers, which has been reviewed through a sincere effort here to give critical view about intercropping in minor millets for agricultural sustainability to the farmers, researchers and consumers.

Multi-hazard susceptibility model based on high spatial resolution data-a case study of Sali settlement (Dugi otok, Croatia).

The world has been facing an increase in various natural hazards. The coastal regions are recognized as one of the most vulnerable due to high population pressure and climate change intensity. Mediterranean countries have one of the most burnable ecosystems in the world, one of the most exposed to pluvial floods, and have the highest erosion rates within the EU. Therefore, the aim of this study was to develop the first multihazard susceptibility model in Croatia for the Sali settlement (island of Dugi otok). The creation of a multi-hazard susceptibility model (MHSM) combined the application of geospatial technology (GST) with a local perception survey. The methodology consisted of two main steps: (1) creating individual hazard susceptibility models (soil erosion, wildfires, pluvial floods), and (2) overall hazard susceptibility modeling. Multicriterial GIS analyses and the Analytical Hierarchy Process were used to create individual hazard models. Criteria used (32) to create models are derived from very-high-resolution (VHR) models. Two versions of MHSM are created: 1) all criteria with equal weighting coefficients and 2) weight coefficients determined based on public perception. According to MHSM 1, most of the research (58%) area is moderately susceptible to multiple hazards. Highly and very highly susceptible areas are 27% of the drainage basin and are mostly located near roads and houses. MHSM 2 reveals similar results to MHSM 1. The public perceives that the research area is the most susceptible to wildfires. The wildfire ignition risk is ranked as moderate (3.00) with a standard deviation of 1.16. Pluvial flood risk is ranked low (2.78), with a standard deviation of 1.15. The risk of soil is most inferior (2.24) with a standard deviation of 0.91. The the most significant difference between public perception and the GIS-MCDA model of hazard susceptibility is related to soil erosion. However, the accuracy of the soil erosion model was confirmed by ROC curves based on recent traces of soil erosion in the research area. The proposed methodological framework of multi-hazard susceptibility modeling can be applied, with minor modifications, to other Mediterranean countries.

Assessment of potential soil degradation on various land uses in Keduang Watershed

Keduang watershed is a catchment area in the Wonogiri and Karanganyar districts, contributing 38.33% of sedimentation to the Gajah Mungkur Reservoir. High value population pressure is present on agricultural land in the Keduang watershed, triggering increasingly serious land degradation. Degradation in the upstream sub-watershed has a strong effect on the downstream areas. Impacts of land degradation include a decrease in land productivity and farmers’ income, as well as the occurrence of critical land. Assessment of the potential soil degradation is important as an early indicator to determine the distribution of areas that have potential soil degradation for physical, chemical, and biological soil. This research was conducted in the Keduang watershed with the land use type consisting of paddy field, wood, moor, and plantation that overlayed through land use, rainfall, slope, and soil type map. The method used in this research is guided qualification. The result showed that the Keduang watershed has a soil degradation class from low to high. The medium class dominated the potential for soil degradation in Keduang watershed with the highest potential for degradation refers to moor with a slope of >40%, rainfall of 1908 mm/year, and Inceptisols soil type.

Solid waste disposal site selection analysis using geospatial technology in Dessie city Ethiopia

Urban environments, especially metropolitan places like Dessie with a high population, result in an increased output of waste. Waste pickers have collected the solid waste from the main road and the immediate area for truck dumping in the river downstream to Kombolcha town, all of these waste materials were deposed, and open burned in the final destination. The best way to deal with this issue is to find a proper waste disposal location in the area as the aim of the paper. To be justified, although, a number of previous related studies have been conducted with their main focus on the physical parameter to identify landfill suitability sites. In this study, not only consider the physical parameters but, also socio-economic parameters were considered, and it is still crucial to generate site-specific information. As a result, by choosing acceptable waste disposal sites using geospatial technology, the study has been undertaken to address the issues of environmental deterioration and the spread of infectious illnesses that are caused by incorrect garbage dumping and open burning in the City. A mixed research design was employed for this research. Since all the data used were processed through the application of software and formulas to produce the result in the map and numerical values which needs a detailed narration. Land use, land cover, slope, drainage, places of worship, groundwater wells, schools, soil, urban core, and population were taken into consideration. These elements were examined in terms of their parametric compatibility. To create a study waste suitability map using geospatial technology, all of the parametric appropriateness was weighted in the overlay analysis according to their respective values, which were obtained from the analytical hierarchal process (AHP). The categories included unsuitable, less suitable, moderately suitable, suitable, and highly suitable. Approximately 71% of the research area was unsuitable for the disposal of solid waste, while the remaining 29% was suitable for the disposal of solid waste concerning drainage, the weighted suitability map shows unsuitable areas were 40.8%, less-suitable areas were 17.6%, moderately suitable areas were 10%, suitable areas were 13%, and highly suitable areas were 18.6%. Existing potentially appropriate and highly suited waste disposal sites were located away from built-up, urban centers, religious institutions, and schools where high population pressure to reduce the detrimental influence on the environment and human health. Therefore, the study results strongly suggested that the current waste treatment area should be avoided and planted in highly suitable and suitable areas.

The role of natural resources, clean energy and technology in mitigating carbon emissions in top populated countries

This study highlights the significance of natural resources, clean energy production, and technological advancement to control carbon emissions and to attain COP-26 targets in populous counties of the World. The empirical investigation is based on 30 years (1990–2019) of data analysis of 14 world’s highly populated countries. This study tries to investigate the aforementioned relationship by employing CS-ARDL econometric techniques that mitigate Cross-sectional Dependence and heterogeneity in slop parameters across panels. For this purpose, the study employed some additional independent variables such as economic growth. The empirical findings reveal the facts that high reliance on natural resources to earn more rent worsen the environmental quality. While, clean energy, and technological innovation brings economies toward a clean natural environment through carbon mitigation. The study suggests that the abundance of green natural resources, efficient use of natural resources may help to protect the natural environment even in those countries which are experiencing high population pressure. In addition, the study spot lights that clean energy production and improvement in technology are also helping to achieve the carbon neutrality targets of COP-26 in highly populated economies of the world.

New neighborhood, old habits? Delivery preferences of residents in new development areas and their assessment of alternative parcel logistics concepts: a case study of Berlin

Various alternative solutions for sustainable last-mile parcel deliveries have been piloted and partially put into operation in Europe in the past decade. However, these delivery concepts have mainly been considered in inner-city areas. There are a few examples of the application of these concepts in peripheral urban areas, where new housing is being built to accommodate high population pressure. However, it is unclear whether the delivery preferences of residents in new neighbourhoods differ from those of the population average. This research conducted a case study in the western outskirts of Berlin, examining two newly built neighbourhoods and one existing residential area. Results from three survey waves of residents (N = 645) show that conventional doorstep delivery is preferred by 80% of the respondents. Nonetheless, there is a high willingness to use alternative delivery options, and respondents see benefits in climate-friendly delivery methods. This research also examines the willingness to pay for alternative parcel logistics concepts, which seems to be too low at the moment (at around €1 per shipment) to compensate for the additional costs of an operational change. However, the results also show an increasing awareness of and preferences for new delivery concepts, thus providing practical implications for planners and logistics operators alike.

Spatiotemporal Dynamic of Land Use/Land Cover Changes and Their Drivers in the Fincha' a-Neshe Sub-Basin, Southeastern Blue Nile Basin, Ethiopia

It is paramount to evaluate the spatiotemporal dynamics of land use and land cover (LULC) changes and their drivers. This is because it helps generate information on biodiversity, land productivity, ecology, and livelihoods for decision-making. Due to land degradation, deforestation, shifting cultivation, high population pressure, and the three national megaprojects (NMPs), the Fincha'a Neshe sub-basin (FNSB) LULC, changes may be unprecedented. This study aimed to investigate the spatiotemporal dynamics of LULC changes and their drivers using remote sensing (RS) data and geographic information systems (GIS). Landsat images 5, 7, and 8 were used for the discrete periods of 1986, 2000, and 2016, respectively. Field observations (Ground control points) and interviews were conducted with key participants to validate the data. Supervised classification with a maximum likelihood algorithm was used to classify the Landsat imagery. The results showed that the FNSB experienced substantial changes in LULC between 1986 and 2016, of which 13.8% (457.3 km2 ) were due to NMPs. The cropland cover has expanded by 694.4 km2 (57.81%) at a rate of 24.60 km2 year-1 at the expense of shrubland, forest, wetland, and grassland. In contrast, shrubland, forest, wetland, and grassland have declined at the rates of 16.8, 3.9, 3.4, and 1.7 km2 year-1 over the entire study period. Population growth and NMPs were the principal drivers of the changes in the LULC of the sub-basin. Thus, the LULC transformation rate observed in the sub-basin requires due attention and mitigation strategies, as it might seriously threaten the sustainability of natural resources and NMPs.

Climatic Impact of Cross-Timber Production and Ecosystem Services on Profit Efficiency

The Cross-Timbers is a forested region that stretches from southern Kansas to central Oklahoma and into Texas. As an essential transitional ecotone between the eastern forest and Great Plains grassland biomes, this region is crucial for maintaining biological diversity. Much of this land is not actively managed for the critical ecosystem services that benefit people living in the region. The Cross-Timbers face threats from natural and anthropogenic factors, including climate variability. The lack of proper forest management (prescribed fires and thinning’s) has resulted in a reduction of wildlife habitats and water availability, and an increased risk of wildfires surrounding human development. These losses in ecosystem services are concerning given the high population pressure, with over 17 million people projected to be directly dependent on these services by 2040. Therefore, analyzing the economic capacity of the region to efficiently use and provide natural resources is critical for improving economic wealth. Efficient forest management practices can result in increased forest productivity and profitability, leading to the development of markets for other non-timber benefits, such as carbon sequestration, hunting, biodiversity, water production, and recreational activities. These practices can position the Cross-Timbers forests as a feasible commodity for emerging natural resource markets. To assess the economic efficiency of the region's forests, we applied stochastic frontier analysis, which measures profit efficiency. Using data from the USDA Forest Inventory and Analysis program at the forest plot level between 2004-2019, we examined the impacts of forest management practices, natural disturbances, and climatic variables on profit efficiency. Our results indicate that the Cross-Timbers forests are economically inefficient in the provision of ecosystem services. Damage caused by abiotic factors reduces profit efficiency by 3.4%, while damage caused by biological factors increases profit efficiency by 23%. The productivity of the site also increases profit efficiency by 17%. Overall, forests in this region generate negative profits when providing ecosystem services. Kansas forests generate higher and more stable profits over time than those in Oklahoma and Texas, and managing softwoods shows to be a more economically attractive alternative than managing oaks, which show the largest variability in profits across the three states.

Urban Leopards of National Capital: Estimating Density and Occupancy of Leopard (Panthera pardus) in Asola Bhatti Wildlife Sanctuary, New Delhi, India

Studies, in recent past have revealed that obligate carnivores are adapting to human dominated landscapes. Leopards, amongst other large carnivores are highly adaptable and can survive in a range of environments. Although any sporadic sightings of leopards have occurred in New Delhi. However, any reliable population and occupancy estimation was lacking from the region, whereas understanding of population density estimation is important in providing local and regional level conservation and management of the species. Our study is conducted to better understand leopard status and population density estimation in Asola Bhatti Wildlife Sanctuary of New Delhi. During 588 camera trap nights, we detected 8 individual leopards. Based on spatial capture-recapture framework the leopard density inside the sanctuary was estimated at 4.5 ± 0.019 leopards/100km² despite very high anthropogenic pressure. Occupancy modelling based on Inverse Distance Weighted Interpolation showed species distribution across the sanctuary which was highest in the areas adjoining densely populated region of the city from where it was observed that large number of vehicle and people cross the sanctuary daily to for their work. The moderate leopard density in this small protected area with high human population pressure can be due to the absence of any other large carnivore, less competition with co-predators because of their low numbers (i.e., hyenas), high availability of prey base and inclusive protected area management. We encourage further research to explore the landscape connectivity between the neighboring suitable leopard habitats like Sariska Tiger Reserve in Rajasthan, via Aravalli hill range of South Haryana till Asola Bhatti Wildlife Sanctuary of New Delhi for understanding wildlife corridor connectivity in the Northern Aravalli Range at landscape level

Standardization of Protocols for Plant Growth Media and Seasons for Cuttings of Kusum [Schleichera oleosa (Lour.) Oken

Growing cuttings of Kusum (Schleichera oleosa), is a major hurdle for the Lac growers in India. This species is primarily known as the lac host tree for lac production besides other multiple uses. Due to high population pressure and market demand, the natural population and genetic diversity of this species is declining day-by-day. Maintaining the selected best germplasm through clonal propagation is the need of the hour. Mass multiplication through cuttings could only be the right choice of the grower if found successful. But, no successful cuttings of Kusum have been reported till date. Therefore, an experiment was carried out during 2018-21 following Completely Randomized Design (CRD) to standardize the plant growth media and the seasons for growing cuttings at the very initial stages of the experiment. The result revealed that the root, shoot and leaf growths in cuttings of Kusum are significantly influenced by the different plant growth media. The maximum rooting initiation (43.33±0.96%) was observed in the cuttings grown in media of Coco peat : FYM : Vermicompost (2:2:1). The maximum rooting (44.50±1.85 %) in the cuttings prepared from seedlings of less than 5 years old and 33.75 ± 1.49 % rooting in the cuttings prepared from 10-20 years old plantation, were recorded in the month of May. Based on the present investigation, it is concluded that the plant growing media having the composition of Coco peat : FYM : Vermicompost (2:2:1) is more appropriate and recommended for growing cuttings of Kusum. Moreover, the month of May is highly recommended for growing cuttings of Kusum for maximum success. Regarding selection of mother plant, it is advised to select the Kusum plant from the plantation aged less than five years old.

Combined impacts of future climate-driven vegetation changes and socioeconomic pressures on protected areas in Africa.

Africa's protected areas (PAs) are the last stronghold of the continent's unique biodiversity, but they appear increasingly threatened by climate change, substantial human population growth, and land-use change. Conservation planning is challenged by uncertainty about how strongly and where these drivers will interact over the next few decades. We investigated the combined future impacts of climate-driven vegetation changes inside African PAs and human population densities and land use in their surroundings for 2 scenarios until the end of the 21st century. We used the following 2 combinations of the shared socioeconomic pathways (SSPs) and representative greenhouse gas concentration pathways (RCPs): the "middle-of-the-road" scenario SSP2-RCP4.5 and the resource-intensive "fossil-fueled development" scenario SSP5-RCP8.5. Climate change impacts on tree cover and biome type (i.e., desert, grassland, savanna, and forest) were simulated with the adaptive dynamic global vegetation model (aDGVM). Under both scenarios, most PAs were adversely affected by at least 1 of the drivers, but the co-occurrence of drivers was largely region and scenario specific. The aDGVM projections suggest considerable climate-driven tree cover increases in PAs in today's grasslands and savannas. For PAs in West Africa, the analyses revealed climate-driven vegetation changes combined with hotspots of high future population and land-use pressure. Except for many PAs in North Africa, future decreases in population and land-use pressures were rare. At the continental scale, SSP5-RCP8.5 led to higher climate-driven changes in tree cover and higher land-use pressure, whereas SSP2-RCP4.5 was characterized by higher future population pressure. Both SSP-RCP scenarios implied increasing challenges for conserving Africa's biodiversity in PAs. Our findings underline the importance of developing and implementing region-specific conservation responses. Strong mitigation of future climate change and equitable development scenarios would reduce ecosystem impacts and sustain the effectiveness of conservation in Africa.

Microplastics in Marine Nearshore Surface Waters of Dar es Salaam and Zanzibar, East Africa.

Limited information exists on the occurrence of microplastics (MPs) in East African coastal waters. A 300μm manta net was used to collect surface water from 8 sites in the regions Dar es Salaam (DES) and Zanzibar (ZZ) during low and high tides. DES had a higher (p < 0.05) abundance of MPs than ZZ. Fragments and fibers were the dominant MP types at all sites. The number of fibers was significantly higher (p = 0.002) in DES than in ZZ. MPs were more prevalent during high tide in both DES and ZZ. The MPs within the 2-5mm size range were identified most often. White and blue MPs were the most common in study sites comprising 45% and 18% of the total MPs respectively. Three polymers polypropylene (PP) high-density polyethylene (HDPE) and low-density polyethylene (LDPE) were identified. The occurrence of MPs in nearshore waters of DES and ZZ is probably due to their proximity to industrial areas, poor solid waste management, and high population pressure.

Inferring Long-term Land-use Development Through On-site Botanical Analyses at Øvre Øksnevad, Southwestern Norway

ABSTRACT This study analysed pollen and plant macrofossils from mainly Bronze Age and Iron Age funerary, agricultural and settlement remains, to infer local plant exploitation and long-term land-use development at Øvre Øksnevad in southwestern Norway. The results showed that deciduous woodland covered the site prior to c. 2100 BC. After this, until c. 500 BC, the vegetation became dominated by grasses/herbs, while several phases of land clearance and cultivation were identified. The main human activity on the site was c. 600-300 BC, when a settlement was established and most of the 103 cairns registered at the site were constructed. Grazing on heathland was the main land-use from 300 BC, until another short-lived settlement was established c. AD 1-200, while regular burning of the heathland occurred from c. AD 1300. The relatively short-lived settlement at Øvre Øksnevad suggests it was marginal and only used during times of high population pressure, a conclusion which is supported by the botanical evidence. This study demonstrates how comprehensive sampling for botanical remains can contribute to the understanding of complex archaeological sites, including local land-use development and human-plant interactions.

Modeling of Cellular Automata Markov Chain for Predicting the Carrying Capacity of Ambon City

Ambon is a city with the highest economic and population growth in Maluku Province, which makes built-up land have high and rapid growth so that it can reduce the carrying capacity of the city's land. This can lead to an imbalance between population and available housing and may result in higher population pressure on available areas. Prediction of spatial modeling is needed as a preventive measure to prevent excessive land cover changes in the future. This study aims to analyze the carrying capacity of residential areas and spatial modeling of land cover changes in Ambon City in 2010, 2015, and 2020 using Cellular Automata Markov Chain (CAMC) and identify settlement patterns based on population density in 2031 in Ambon city. The results of the Cellular Automata Markov Chain (CAMC) analysis show that the residential area in 2031 has increased to 7,910.03 ha and the development of residential areas in 2031 in Ambon City is centered on Sirimau District.&#x0D;

SEVERITY OF CORN STUNT DISEASE ON MAIZE GENOTYPES IN THE MIDWEST OF THE BRAZILIAN STATE OF SANTA CATARINA

In an attempt to provide regionalized information about maize genotypes’ response to corn stunt disease complex, this study evaluated the corn stunt disease severity and productivity of conventional (7) and transgenic (11) maize genotypes under natural infestation of its insect vector, Dalbulus maidis (Hemiptera: Cicadellidae). The work was carried out in Campos Novos, SC, Brazil, during the 2020/2021 crop season. In a randomized block design, the genotypes were sowed in experimental plots of 14 m2 , with four replicates (plot) per genotype. At 90 days after sowing, the severity of corn stunt disease was analyzed using a visual symptoms scale, while the maize productivity was assessed at physiological maturation. There was variability for response to stunt disease in the genotypes and a negative correlation between severity and grain yield. Among the conventional genotypes, P3456, FS055, SCS154 Fortuna, SCS156 Colorado, and SCS155 Catarina had lower severity of corn stunt disease. For the transgenic genotypes, AS1757 PRO3 and P3551 PWU were more resistant, while B2418 VYHR, AG9025 PRO3, and P1225 VYHR had high corn stunt disease severity. The corn stunt severity varied from 1 (absence of symptoms) in P3551 PWU to 4.8 (more than 75% of leaves with symptoms) in P1225 VYHR, while the lowest and highest yields were obtained for BG7056 (1,253.7 kg.ha-1) and P3016 VYHR (9,794.6 kg.ha-1), respectively. The genotypes with low corn stunt disease severity are suitable options for sowing in the Midwest region of Santa Catarina, Brazil, in conditions of high population pressure of D. maidis.
