The national ecolabel of tourist accommodation establishments and rural tourism enterprises of Latvia – the ‘Green Certificate’ (hereinafter the ‘Green Certificate’) celebrated its 20th anniversary in 2019. Its creation in 1999 was initiated by the Latvian Rural Tourism Association ‘Baltic Country Holidays’, and it is currently one of the oldest European ecolabels still in operation. One of the most significant tourism and rural tourism resources in Latvia is the natural and cultural heritage, which is the basis for the development of rural tourism products. In this process, ecosystem services used in tourism products play a major role. One of the goals of the ‘Green Certificate’ is environment, nature and local society friendly and sustainable farming, which means both a careful use of natural resources and their inclusion in the tourism product development process. The aim of this study was to find out which ecosystem services were used and the ways they were used by rural tourism companies to create the nature protection, social and economic added value. According to the respondents, 1/3 of the revenue of the ‘Green Certificate’ companies is generated by the use of the ecosystem services. It is an argument for further research on the possibilities of the ecosystem services to be used more effectively in future in developing new rural tourism products.

In the 21st century, urban agriculture renews and diversifies approaches to the practice within the context of urban regeneration, climate change risks, and sustainable development and resource consumption balance problems. Influenced by the long historical evolution and intensification of various risks, food production in urban areas involves the widest multifunctionality to date. Therefore, the aim of this research is to identify the main functions of urban agriculture and to evaluate their significance in Latvia. The following tasks were set to achieve the aim: 1) to identify and classify functions of urban agriculture, 2) to analyse the performance and significance of functions in Latvia. Several methods were employed to perform tasks and achieve the aim: the monographic and descriptive methods for making a theoretical discussion; the analysis, synthesis and deduction methods for obtaining information, systematisation and classification of functions; a structured expert interview for rating and ranking functions and identifying interactions between them. The research identified 14 functions of urban agriculture, which were classified into 5 groups: political, economic, social, environmental and technological. The most significant functions of urban agriculture in Latvia are social (promotion of social cohesion and public health, education and maintaining traditions and values) and technological innovations. There are interactions between all functions, and support for urban sustainability, education, provision of ecosystem services and technological innovations have the strongest impact on other functions. Interactions of functions proved the multifunctionality of urban agriculture, which could be an important support tool to contributing to sustainable urban development.
