This paper presents the procedures used to develop a strategy to mitigate flooding in the Bayou Henderson watershed in Ascension Parish, Louisiana. The Bayou Henderson Watershed includes the town of Galvez, Louisiana, and has an area of approximately 3600 hectare. A little more than one-third of the watershed is developed, while the remainder is open or forested areas. The watershed includes agriculture/pastureland, residential, open space and some commercial areas. A map of the Bayou Henderson watershed showing the stream network and land use are provided in Figure 1 . The main stem of Bayou Henderson is approximately 10 kilometers in length. It flows southeast until it crosses Henderson Bayou Road. From there, Bayou Henderson flows northeast until it discharges into the Amite River. Bayou Henderson has several major tributaries which drain the urbanized areas in the western part of the watershed. The elevation of the Bayou Henderson channel ranges from about one meter below sea level near its confluence with the Amite River to approximately 6 meters above sea level at the upstream most reaches on the Marty Burratt drainage ditch. The entire Bayou Henderson watershed is located within the Mississippi River 500-year floodplain. In additional, a large area of the Bayou Henderson Watershed is affected by backwater from the Amite River and is included within the Amite River 100-year floodplain. Two types of flooding affect residences and businesses in Henderson Bayou. The first of these is local flooding, which results from heavy rainfall in the immediate drainage area of the Bayou and its tributaries. This type of flooding has worsened in recent years because of increased paved area and floodplain encroachment. The second type of flooding is known as backwater flooding or tailwater flooding. It is caused by flood flow and high water in the Amite River, which then restricts the discharge of Bayou Henderson. These two types of flooding are generally considered to be independent, meaning the underlying causes are not correlated. Therefore, local flooding and backwater flooding can occur individually or jointly from time to time.

The agriculture and horticulture sector in the Netherlands is one of the most productive in the world. Although the sector is one of the most advanced and intense agricultural production systems worldwide, it faces challenges, such as climate change and environmental and social unsustainability of industrial production. To overcome these challenges, alternative food production initiatives have emerged, especially in large cities such as Amsterdam. Some initiatives involve producing food in the urban environment, supported by new technologies and practices, so-called high-tech urban agriculture (HTUA). These initiatives make cultivation of plants inside and on top of buildings possible and increase green spaces in urban areas. The emerging agricultural technologies are creating new business environments that are shape d by technology developers (e.g., suppliers of horticultural light emitting diodes (LED) and control environment systems) and developers of alternative food production practices (e.g., HTUA start-ups). However, research shows that the uptake of these technological innovations in urban planning processes is problematic. Therefore, this research analyzes the barriers that local government planners and HTUA developers are facing in the embedding of HTUA in urban planning processes, using the city of Amsterdam as a case study. This study draws on actor-network theory (ANT) to analyze the interactions between planners, technologies, technology developers and developers of alternative food production practices. Several concepts of ANT are integrated into a multi-level perspective on sustainability transitions (MLP) to create a new theoretical framework that can explain how interactions between technologies and planning actors transform the incumbent social–technical regime. The configuration of interactions between social and material entities in technology development and adoption processes in Amsterdam is analyzed through the lens of this theoretical framework. The data in this study were gathered by tracing actors and their connections by using ethnographic research methods. In the course of the integration of new technologies into urban planning practices, gaps between technologies, technology developers, and planning actors have been identified. The results of this study show a lacking connection between planning actors and technology developers, although planning actors do interact with developers of alternative food production practices. These interactions are influenced by agency of artefacts such as visualizations of the future projects. The paper concludes that for the utilization of emerging technologies for sustainability transition of cities, the existing gap between technology developers and planning actors needs to be bridged through the integration of technology development visions in urban agendas and planning processes.

The article discusses the problems associated with the tourism industry and the hotel business during the pandemic. A study was carried out and relevant conclusions were presented on how the pandemic affected the hotel business in Europe and Russia. The authors examined and analyzed in detail the indicators of forecasts in the sphere of the Russian hotel business, particularly in the regions. The authors paid special attention to the study of open public spaces and conducted a detailed analysis, which made it possible to identify the opportunities for the development of the hotel business. In the article the main trends of a pandemic and post-pandemic are studied – the need to reinforce sanitary measures. The research focuses on identifying the features of the economic state of the regions during the pandemic. The authors developed and substantiated the areas that are relevant, useful and applicable for the hotel business; revealed the features of the process of restoration of the hotel business. Special attention is paid to the study of state support measures; the features of their further actualization for the development of the tourism industry are presented. The authors have proposed the ways to overcome the crisis, contributing to a slow, but accurate and safe recovery of the hotel business and an increase in demand.

The paper proposes a critical assessment of municipal solid waste gasification today, starting from basic aspects of the process (process types and steps, operating and performance parameters) and arriving to a comparative analysis of the reactors (fixed bed, fluidized bed, entrained bed, vertical shaft, moving grate furnace, rotary kiln, plasma reactor) as well as of the possible plant configurations (heat gasifier and power gasifier) and the environmental performances of the main commercially available gasifiers for municipal solid wastes. The analysis indicates that gasification is a technically viable option for the solid waste conversion, including residual waste from separate collection of municipal solid waste. It is able to meet existing emission limits and can have a remarkable effect on reduction of landfill disposal option.
