The results obtained and their novelty: are concluded, first of all, in study disease populations, factors of the condition and territorial structures speciality with point of view economic and social geography. In dissertation is studied also theoretical and practical questions of medical geography, analysis and estimation nozogeographic situations different territory bring physician-geographical regionalization Uzbekistan.
Practical value: the main scientific-practical conclusions and recommendations of dissertation can be used in reform systems public health as well as in improvement territorial organizations of sphere of the medical servicing the population.
Degree of embed and economic effectivity: the mail recommendations and suggestions, resulting from research, have been used at the State Committee Departments of protection of Nature, Ministry of Health of the Republic of Uzbekistan, Institute of health and medical statistics under Ministry of Health of the Republic of Uzbekistan and at the educational process on the faculty of geography of NUUz.
Field of application: State Committee Departments of protection of Nature, Ministry of Health of the Republic of Uzbekistan, hokimiyats of regions, higher educational institutions and others.

Subjects of the research: irrigated and degraded parts of the geo-system of Syrdarya region.
Aim of the research: determination the changes in the main features of irrigated geo-system of the Hunger Steppe under the condition of decrease in the Syrdarya River runoff and the development of ecological methods for improving their fertility.
Methods of research: systematic-structural analysis, field research, field experiments, laboratory analysis, cartographic, agro-cosmic, working with educational aids and fund materials, exchange rates of water-salt and energy, geographic and geochemistry analysis, comparison.
The results achieved and their novelty: On the basis of artificial water shortage in Syrdarya basin, water and salt exchange processes in irrigated lands of Syrdarya region were studied; on the basis of natural and anthropogenic features the decreasing quantity of productivity of irrigated lands and harvest was estimated; Salinity of irrigated geo-systems of Syrdarya region, agrochemical and changes in water-physic features were defined; the features of water -salt turnover in the agrolandscapes and soil-ameliorative processes were studied depending on natural factors and anthropogenic impact of the operation modes of the large reservoirs; productivity of using fito-ameliorants in the improvement of ameliorative condition was determined in field experiments.
Practical value: dissertation results and scientific-methodical
recommendations can be implemented in the department of Agriculture and Water Management, land cadastre and nature protection departments, in the processes of basin irrigation systems and working out processes of improvement of ameliorative conditions of lands as well as in education processes.
Degree of embed and economic effectivity: the degree of the work was brought into extension in education process at Gulistan State University. The recommendations on the development of soil-ameliorative processes were given to the farmers of “Galaba” in Bayaut district.
Fieid of application: departments of the Ministry of Agriculture and Water Management, scientific-research institutes, educational institutions, departments of amelioration service and farms.

Subjects of the inquiry: the urban places ot the Bukhara region.
Aim of the inquiry: to analyze the developing position of the cities in desert condition of Bukhara region and elaborate their scientific and practical recommendations in the future.
Methods of inquiry: statistic, cartographic, historic, comparative-geographical, system-structure, also methods of the research and prognosis.
The results achieved and their novelty: the peculiarities of the natural desert condition has been influenced on regional organization and development of the cities, urban places and their systems has been analyzed, the effect of natural-geographic patterns on development of cities has been discussed, urban places and their systems have been analyzed, with the help of the Government’s program, which called “The year of village development and improvement”, the growth of the new towns and village-districts of Bukhara region has been talked over, environment of the capital investment and system of the infrastructure has been conferred, demographic and gco-ccologic condition has been learned, their developing problems and directions were grounded prospectively.
Practical value: the main results and conclusion of the research may be used to elaborate the regional program of complex social-economic development, in solution of the urban problems in desert condition, in controlling the state of urbanization and the method of approach and statistic materials will be used in process of the higher educational establishments.
Degree of embed and economic affectivity: the main conclusion and recommendations have been accepted to inculcate by Bukhara region and Gazli city, the educational department of BukhSU.
Sphere of usage: the Government of Bukhara region and cities, the higher educational establishments.

Climate change is reshaping human mobility across the planet. Climate-related hazards such as floods, storms, and wildfires have already become major drivers of global human mobility. Policy advancements in the field of climate migration are unprecedented and critical, as they have impacts not only on a global scale but also at regional, national, and sub-national levels. These policies are especially important for countries and populations most vulnerable to climate change, particularly the least developed countries, landlocked developing countries, and small island developing states.

The aim of research work is the identification and verification of destruction and degradation peculiarities, estimation of limits of reconstruction of anthropogenous gcosystems and development of recommendations for management of regimes of their functioning.
Scientific novelty of research work:
scientifically substantiated forecast of the dynamics change based on the isobaths of the gcosystems of the delta of Amu Darya and the dried part of the bottom of the Aral Sea up to 2030;
the features and types of salt accumulation in the soils of delta plains and the dried part of the bottom of the Aral Sea arc established;
indicators of hydrological and hydrochcmical processes arc revealed depending on the lithologic-gcomorphological structure of natural-meliorative complexes;
the method of mapping the danger of desertification is different from the known methods, taking into account the natural conditions of the local arid zones of the region, which allows determining the discharges, rates, area, number and criteria of the danger of internal and general desertification;
the method of determining the zones of expected desertification for the coming years is different from the known analogs, taking into account the role of local landscape-indicator processes operating in the zone of degradation and degradation of geosystems, as well as anthropogenic, technogenic and natural factors;
the method for creating forest plantations, which differs from the known methods in accelerating the drying of the dried bottom of the Aral Sea, was improved, by facilitating the natural replacement of local, focal, narrow-band, broadband, pasture, meliorative and fodder logging, allowing for the shortest possible time to cover the dried bottom of the sea and reduce to a minimum crisis situation in the region.
