This research aims at throwing light on applications of biological rapid assessment tools in the monitoring of environmental quality in Runde River catchment with intensive commercial sugarcane production. Burdened with drudgery in wet laboratory techniques, biological sensors (biosensors) and sensors can integrate catchment data from rapid assessment techniques to networks or Internet of Things (IoT). This research examines the techniques presented by biosensors and sensors and provides the checkboxes for sustained catchment monitoring. With available recent evidence from surveys it turns out the Runde River may not be polluted but this may reflect the time the survey was undertaken and suggestions made for routine checks

Drinking Water Sources

Most water supply programmes in Cambodia have focused on providing access to bacteriologically safe water, an approach which has led to an increasing reliance on ground water, especially in rural areas. However, there have been very few data collected on the chemical quality of the nation's drinking water sources, and few water supply programmes have the capacity to assess chemical quality. The study was designed to address this data gap by conducting a low-cost, rapid assessment of drinking water sources nationwide to determine whether there were any chemicals of concern in Cambodian water supply sources. Results of the assessment confirm that there are several parameters of health and aesthetic concern; dissolved arsenic is the most significant. Elevated arsenic levels (some exceeding 500 μg l-1) were detected in aquifers of moderate depth in several highly populated areas, confirming that further investigation of the occurrence of arsenic contamination in Cambodia is warranted. Other chemicals of health concern include nitrate, nitrite, fluoride and manganese. Additionally, many ground water sources are negatively impacted by parameters of aesthetic concern, such as iron, manganese, hardness and total dissolved solids. Elevated levels of these parameters have caused consumers to reject newly installed water supplies, often in favour of surface water sources that are bacteriologically unsafe.

Abstract Smith, C. J., Banks, A. C., and Papadopoulou, K.-N. 2007. Improving the quantitative estimation of trawling impacts from sidescan-sonar and underwater-video imagery. – ICES Journal of Marine Science, 64: 1692–1701. The techniques of sidescan sonar and towed, underwater-video sled were assessed as rapid-assessment methodologies for investigating trawl impacts on the substratum. Sidescan sonar is able to image a swathe of ∼200 m with a resolution of ∼20 cm at a speed of 2–3 knots, and marks of trawl doors could be observed. The towed video system imaged a swathe of 1–2 m with a resolution of 1–2 cm at a speed of ∼1 knot, and trawl-door marks, scrape marks, local bioturbation features, and fauna could be observed. Multiple tows using both methodologies were carried out in two areas in Heraklion Bay, Crete. One area, experimentally trawled, was 80–90 m deep and characterized by mixed, maerly sediments; the other was a commercial trawl lane ∼200 m deep characterized by silty-clay sediment. Descriptions of the types of trawling feature and impacts caused by trawling were made for both areas. Images were analysed from the commercial deeper trawling ground for area assessment. For sidescan-sonar records, direction of trawling and trawl-mark density by category were estimated at periodic intervals along the track. For video, categories for trawl-mark density and level of bioturbation were estimated, along with the density of the crinoid Leptometra phalangium. Using geo-referenced positioning for each data point, area maps were constructed for each of the parameters, and correlations were tested between the different datasets. The use of the assessment techniques (characteristics, data usage, mapping, complementarity) in relation to trawling-impact studies is discussed, as well as possibilities for the use of the resulting data for management.

The COVID-19 pandemic has had strong impact on the tourism market. As a result of the lockdown and the closing of borders, tourist traffic came to an abrupt halt. Agritourism is an important way of diversifying agriculture and rural areas. In addition, it is a part of the idea of sustainable and multifunctional agriculture. It makes it possible to use production resources in the countryside and constitutes an additional source of income for both farmers and the local community. The aim of the paper was to present the results of survey research concerning the tourist plans of the Polish people in the era of the COVID-19 pandemic, in particular plans to spend holidays on agritourism farms. The study confirmed that according to Polish respondents, holidays in the country, spent on agritourism farms, were a good choice in the era of the COVID-19 pandemic. The respondents expect agritourism providers to take specific actions, i.e., disinfect communal rooms, make hand sanitizers available, as well as limit the maximum number of people allowed on the farm and in open-access rooms, in order to ensure safety during their stay. The article constitutes a contribution to the evolving literature on the impact of the COVID-19 pandemic on the development of the tourism sector.

Ecologically Sustainable

Many of Australia's river systems have been seriously degraded by inappropriate management of regulated flows. Other systems are facing threats from future water resources developments. There is a lack of information available to aid in allocation of environmental flows to rivers in order that they are managed in an ecologically sustainable manner. The Environmental Flows Initiative (EFI) is a major Australia-wide R&D program into environmental flows, funded through the Natural Heritage Trust (NHT), and administered by Environment Australia (EA). The program aims to identify environmental values, undertake targeted research to identify risks to river systems and flow requirements to sustain environmental values, to trial flow management options, and to evaluate these trials. The NHT relies on matching funding provided by the State and Territory authorities, and supports integrative approaches with emphasis on works on-the-ground where possible. While the EFI will close significant knowledge gaps, other gaps remain. Some of these relate to development and validation of rapid assessment techniques, understanding the importance of flow variability and how to define it, manipulation of flows to control alien species, developing a system of prioritising rivers for environmental flows, and enhancing flows with other catchment, channel and floodplain rehabilitation measures.
