Zinātnisko rakstu krājumā iekļauti VIII starptautiskās zinātniski praktiskās konferences “Vide. Tehnoloģija. Resursi” raksti. Rakstu tematika saistīta ar vides kvalitāti, tās kontroli un nodrošināšanu, piesārņojuma novēršanas tehnoloģijām, tīrāku ražošanu, ilgtspējīgo lauksaimniecību, dabas resursiem, degradēto teritoriju atjaunošanu, vides izglītību un ilgtspējīgo attīstību. Tiek pētītas atjaunojamās enerģētikas problēmas. Rakstu krājumā pārstāvēti referāti, kas ir saistīti ar datorzinātnes, matemātikas, mehānikas un mehatronikas pielietošanu vides zinātnes un citu nozaru problēmu risināšanā. Proceedings include papers presented at the 8th International Conference “Environment. Technology. Resources.” The themes of the papers are – the environmental quality, control and providing, pollution prevention technologies, cleaner production, sustainable agriculture, natural resources, remediation of degraded territories, environmental education and sustainable development. The problems of renewable energy are analysed. A separate section of the conference includes papers on applications of computer science, mathematics, mechanics and mechatronics for solution of environmental and other problems.
