Natural Resource Exploitation

Ethnic minorities in the Northern Mountainous Region not only use the application of scientific-technological advances but also experiences of the community to enhance production efficiency and environmental protection. Local knowledge (TTDP) of ethnic minorities is useful for environmental protection and natural resource exploitation & use. These are environmental & weather knowledge; farming experiences on sloping and forestry land; knowledge about environmental protection and natural resource exploitation & use especially how to protect precious resources by specific rules/regulations of customary law. In the context of declining natural resources, TTDP is eroded, captured, or illegally exploited. There should be measures in order to preserve and promote TTDP as well as raise the awareness of the community about its important role.

Summary. Introduction: Location of weather surveillance radars near settlements, in residential areas and on airport premises makes it important to ensure safe levels of electromagnetic fields (EMF) when operating these radio transmitters. EMF maximum permissible levels for weather radars developed in the 1980s are outdated. Our objective was to analyze modern weather surveillance radars to develop proposals for improvement of radar-generated radiofrequency field monitoring. Materials and methods: We studied trends in meteorological radiolocation and technical characteristics of modern weather radars for atmospheric sensing and weather alerts, analyzed regulations for EMF measurements and hygienic assessment, and measured radiofrequency fields produced by weather radar antennas in open areas and at workplaces of operators. Results: We established that modern types of weather radars used in upper-air sensing systems and storm warning networks differ significantly in terms of technical characteristics and operating modes from previous generations. Developed in the 1980s, current hygienic standards for human exposures to radiofrequency fields from weather radar antennas are obsolete. Conclusions: It is essential to develop an up-to-date regulatory and method document specifying estimation and instrumental monitoring of EMF levels generated by weather radars and measuring instruments for monitoring of pulse-modulated electromagnetic radiation.
