Remote Sensing Technique in Rice Weed Detection
Remote sensing technology aims to monitor and capture the earth’s information without making direct contact and destroying it. The utilization of the electromagnetic spectrum, ranging from visible to microwave for measuring the earth’s properties, is the main idea behind remote sensing technology. Machine learning (ML) and deep learning (DL) remote sensing techniques have successfully produced a high accuracy map for detecting weeds in crops using RS platforms. Therefore, this technology positively impacts weed management in many aspects, especially in terms of the economic perspective. The implementation of this technology into agricultural development could be extended further.

EU Road Transport Carbon Emissions
To accomplish the 1.5 °C and 2 °C climate change targets, the European Union (EU) has set up several policy initiatives. Within the EU, the carbon emissions of the road transport sector from the consumption of diesel and gasoline are constantly rising. (1) Background: due to road transport policies, diesel and gasoline use within the EU is increasing the amount of carbon in the atmosphere and adding to climate risks. (2) Methods: sustainability analysis used was based on the method recommended by the Intergovernmental Panel on Climate Change. (3) Results: to meet its road transport requirements, the EU produces an estimated 0.237–0.245 billion tonnes of carbon per year from its total consumption of diesel and gasoline. (4) Conclusion: if there is no significant reduction in diesel and gasoline carbon emissions, there is a real risk that the EU’s carbon budget commitment could lapse and that climate change targets will not be met. Sustainability analysis of energy consumption in road transport sector shows the optimum solution is the direct electrification of road transport.

The Honey Bee Apis mellifera
The honey bee Apis mellifera Linnaeus (1758) provides many benefits to humans and ecosystems. This species is an important pollinator in natural environments, which may help to preserve and restore the biodiversity of wild plants. On the other hand, pollination in agro-ecosystems by managed honey bee colonies may enhance crop yield and quality, meeting the increasing food demand. Beekeeping is also a high-valued and income-generating activity, which provides humans with honey as high-quality food as well as substances used as raw materials and in pharmaceuticals. In addition, the honey bee and its products are valuable bioindicators and bioaccumulators of environmental pollution: they provide valuable information on the impact of human activities, enabling the implementation of measures to mitigate risks to human and ecosystem health. The honey bee is also linked to many cultural ecosystem services and has a longstanding tradition in human culture, mysticism, and religion. Its popularity may be therefore used for educational purposes and to raise public awareness of important issues, such as the conservation of pollinator habitats and biodiversity.

Flower Strips
Wildflower strips, a semi-natural manmade habitat comprising mixtures of native herbaceous species, can be sown on arable field margins to provide multiple ecological, agricultural and conservation benefits. The main aim of creating flower strips is to enrich the fauna of farmland with the species that are beneficial in terms of the agricultural economy: animals that limit the population density of pests (e.g., parasitic insects, including parasitoids, predatory insects and spiders and birds) and pollinators (insects that feed on pollen or nectar), including those with economic significance. For this reason, flower strips should be included in agri-environmental programs to enhance sustainable plant production and the biodiversity of pollinators on farmland or natural aphid enemies. Flower strips are thus increasingly frequently promoted in environmental programmes, and financial support is being implemented as an additional business incentive.

List of Cities by Sunshine Duration
The following is a list of cities by sunshine duration. Sunshine duration is a climatological indicator, measuring duration of sunshine in given period (usually, a day or a year) for a given location on Earth, typically expressed as an averaged value over several years. It is a general indicator of cloudiness of a location, and thus differs from insolation, which measures the total energy delivered by sunlight over a given period. Sunshine duration is usually expressed in hours per year, or in (average) hours per day. The first measure indicates the general sunniness of a location compared with other places, while the latter allows for comparison of sunshine in various seasons in the same location. Another often-used measure is percentage ratio of recorded bright sunshine duration and daylight duration in the observed period. An important use of sunshine duration data is to characterize the climate of sites, especially of health resorts. This also takes into account the psychological effect of strong solar light on human well-being. It is often used to promote tourist destinations.

Bank Stabilization Structures of Yangtze-River
Bank Stabilization Structures of Yangtze-River are ecological revetment structures that have been carried out in the Yangtze River with a focus on preventing bed-shape evolution, river-width adjustment, and lateral channel migration, which are woody planting and combined applications of planting and artificial structures. The most widely used in the middle and lower reaches of the Yangtze River are steel wire mesh gabions bank stabilization and chain-type bricks bank stabilization.

Nomenclature for Hydrogeological Instability Risks
The nomenclature for hydrogeological instability risks includes four main risks, which are distinguished according to the risk causes : 1) hydrogeological risk, that is slowly caused by natural factors (e.g. collapse landslides in a calcareous cliff in uninhabited areas and erosion along a marly-calcareous slope) in environments where human activities are minimal, i.e. woods, forests and mountain pastures; 2) hydraulic-pedological farming risk, that implies the occurrence of landslides in every winter and is caused by incorrect crop selection, not suitable for the soil and climate parameters (e.g. on a hilly slope with a clay vertisol type with a landslide having different fronts, when the arable land is cultivated with a cereal-legume crop rotation), or the presence of springs with missing drainage in clay soils with a high gradient;3) hydraulic-infrastructural risk, that is caused by the building up of infrastructures not suitable for the surrounding environment, as they change the downflow of shallow water; 4) hydraulic-infrastructural-pedological-management risk, that is caused by crop operations not suitable for soil and crop parameters, where the selected cultivated plant species are suitable for the environment and field improvements change water downflow (e.g. in soils along hilly calcarenite slopes cultivated with olive orchards, where up-down soil tillage causes shallow water erosion).

The Belt and Road Initiative
The Belt and Road Initiative (BRI), proposed by Chinese President Xi Jinping in 2013, is an international initiative with vital implications for the economy, society, culture, and the environment. Consisting of the "Silk Road Economic Belt" and the "21st Century Maritime Silk Road", the BRI was inherited and developed from the ancient Silk Road that played an essential role in connecting the West with the East on various socio-economic levels with its spirit of peace, friendship, inclusiveness, openness, and mutual benefit for many centuries.

Alpha-Emitting Radionuclides in Wild Mushrooms
Alpha-emitting radioisotopes are the most radiotoxic nuclides among all radionuclides. Especially medium- and long-living isotopes that enter the body, are hazardous metals of the greatest importance from the human life point of view. This review focuses on the most common natural and anthropogenic origin alpha-emitting radionuclides in wild mushrooms around the world. Mushrooms are considered as suitable bioindicators of environmental pollution with some metallic elements, for the reason they bioaccumulate a range of mineral ionic constituents including radioactive elements at different levels. Various species have different retain capacities of individual radionuclides. In turn, wild edible mushrooms are food products, mostly consumed regionally and also traded at an international scale. Mushrooms under pollution events situation might cause a risk to consumers due to exposure to highly radiotoxic decay particles produced by alpha emitters.
