The problem of the emergence of illegal dumps in rural areas is considered in the article on the example of the Tashkent region of the Republic of Uzbekistan. It was revealed that the sizes of illegal disposal fields vary from 1.0 to 18,895 m ² , there are dumps for building materials from construction sites, agricultural, household waste, as well...

... must be noted that despite the positive dynamics, these values are far behind the targets set in the Strategy of the Republic of Uzbekistan for the management of municipal solid waste for 2019-2028 (Table 1). Information on the ratio of the number of large official and illegal landfills is given in Table 2 (available data refer to 2017). It can be seen that the number of illegal dumps is 5 times higher than the number of official landfills. ...Similar publications
Among vegetable crops, carrot is one of the main agricultural products for domestic consumption and export in Uzbekistan. For this reason, great attention is paid to its cultivation as a main and repeated crop after grain. Today, in order to earn additional income from the land twice, carrots are planted in the main part of the grain-free areas of...
The article highlights the state and a brief analysis of the technology of soil preparation for cotton sowing in the Republic of Uzbekistan. A constructive scheme of a cotton seeder equipped with soil-loosening working bodies is given, designed for strip tillage of the soil in the zones of occurrence of cotton seeds with a given width and depth and...

... Organisation of processing plants requires appropriate regulatory documentation, financial investments, territories for construction. At present, Uzbekistan has neither regulatory support for solar panel recycling nor e-waste recycling facilities, which represent a real problem in the country [28,29]. Already now, without the involvement of solar energy, the volume of e-waste in Uzbekistan is quite significant. ...
This article is devoted to discussing the issue of solar panel waste in connection with the growing share of solar energy in the Republic of Uzbekistan. The main causes of solar panel failure are end of life, failures during normal operation, and weather-related emergencies. The climatic conditions of Uzbekistan were studied and it was found that in some regions of the country there are strong winds, which are a potential danger for solar panels. Calculations showed that the probability of destructive winds is 0.00045, which can lead to emergency destruction of panels (up to 1,224 tonnes of waste per lifetime). High air dustiness can cause increased water consumption for cleaning the panels (68 times the design flow rate) and consequently an increase in the volume of polluted wastewater. Thus, it is clear that the problem of waste associated with solar energy development has not yet been adequately addressed. In order to take timely action, it is necessary to develop appropriate regulatory documents for accounting and handling of solar energy waste.
... These losses are often associated with a lack of timely and convenient information for public authorities to make correct decisions. Land degradation and pollution are often caused by human activities, particularly illegal waste disposal [4], and the operation and use of road transport waste [5][6][7][8]. Soil salinisation is mainly caused by agricultural activity, which is strongly affected by salinisation. ...
This article examines the economic efficiency of land reclamation measures for desalinating saline land, using the example of a hypothetical farm in the Syrdarya province of Uzbekistan. The evaluation method employed is the calculation of discounted costs. The results indicate that the payback period for works on weakly and moderately saline lands is 4 years and 3 years, respectively, with a net discounted income of 143,678 for the hypothetical farm under analysis. It is established that desalinisation of highly saline lands is unprofitable and they should be excluded from agricultural turnover.
... Further, the low-middle-income cities/countries [43] ranking was performed against the collection efficiency parameter ( Figure 3). Tehran, Tashkent, and Beirut are found at the top rank with 100% waste collection efficiency [44][45][46][47]. Kyiv maintained the second rank with 90% waste collection efficiency [48]. ...
Solid Waste Management (SWM) is a technical subject which requires comprehensive planning, execution, and effective operational monitoring under cost-effective modes compatible with environmentally sound technologies. The policymakers made some enormous efforts for the sustainability of this sector as well as setting a benchmark for other municipalities and Waste Management Companies (WMCs) in the country. Provincial Government prioritizes its focus on SWM, i.e., waste collection, transportation, treatment, and final disposal. The waste management sector in Lahore has achieved sustainability in waste collection and haulage components by gaining experience from international outsourcing and, now, sharing its knowledge with other municipalities to strengthen the sector in the country. Lahore has emerged with the highest collection efficiency (84%) in SAARC countries and placed fifth in rank in comparison to 54 low–middle-income countries/cities worldwide. The sectorial interventions in Lahore reveal an aspiration for the sustainability of the SWM sector in Pakistan. However, there is an urgent need to focus and invest in waste-related infrastructure development, i.e., permanent/mobile transfer stations, semi-underground containers for commercial and planned areas, material recovery facilities (MRF), and landfill. Environmental and economic sustainability in this sector can be achieved through public–private partnership (PPP) modality in compost, anaerobic digestion, recycling, and refuse-derived fuel (RDF) as it is a more feasible option to strengthen the industry in the country.

Assessment of the current SWM sector in Lahore is performed against waste assessment indicators and Lahore has emerged as a clean city in South Asian countries concerning waste collection and haulage services and placed on a rank of fifth among middle–low-income countries. However, there is a need to strengthen this sector in line with emerging waste treatment trends in the region, i.e., waste-to-energy.
Illegal dumping is challenging for municipalities to keep track of and clean. There is limited research on the quantity of illegal dumpsites within cities. Through a manual image interpretation
technique, this study used aerial imagery to quantify all illegal dumpsites within Nelson Mandela Bay Metro, South Africa. All illegal dumps were marked out in 2015 and 2021 aeroplane aerial
imagery at 50 cm and 25 cm GSD, respectively. The total coverage of land surveyed was 1331 km2, with an urban area of 308 km2. The number of illegal dumpsites increased from 4969
to 7800 (57% increase) between 2015 and 2021. The study also showed the quantity of waste within dumps increased, dumps were spatially clustered and close to urban areas and roads. The
technique presented can easily be replicated in other cities to track and monitor illegal dumping.
