Abstract

Riparian zones are environments exceptionally rich in biodiversity but are also among the most threatened ecosystems. With the increase in population pressure, humans are currently causing major disruptions to these environments, which will increase further with climate change. As a result, image-based tools have become essential to characterize these sensitive areas on a large scale, with the aim of promoting biodiversity conservation policies. Copernicus data, available at European level, aim to meet these challenges. In this study, the potential of the Copernicus data was compared with two other very high resolution data sets to determine whether they can assess the ecological integrity of riparian zones using a landscape metric approach. The results showed that the Copernicus data react positively to the influence of an anthropogenic disturbance gradient. However, Copernicus data are not shown as accurate as very high resolution datasets, which can have consequences on the management of these environments. The influence of spatial scale on the structure of riparian vegetation was studied and showed that vegetation near the watercourse is the most affected. This work has also shown the relevance of using the landscape approach but has pointed out a limitation in that this approach has not taken into account the three-dimensional variables, which are essential to characterize riparian environments.

Abstract

Satisfying consumer needs through the production of healthy and nutritious agricultural products is a substantial challenge facing modern agriculture. However, agricultural production should be carried out with care for plant health, biological safety of products, and environmental safety while minimizing the risks to human health. Therefore, the implementation of agricultural practices while respecting these principles is very important for improving the quantity and quality of crops. Additionally, ecosystems have been altered as a result of human activities and climate change, resulting in the reduction of biodiversity and creation of new niches where pests can thrive. This is of particular importance in 2020, as the United Nations General Assembly declared this year as the International Year of Plant Health (IYPH), with “protecting plants, protecting life” as a leading subject.This Special Issue promotes the subject of plant health and emphasize the importance of preventing the spread of pests, including weeds, which cause substantial economic losses. Research articles cover topics related to the biology and harmfulness of weeds, particularly in connection with crop health, segetal weed communities and their biodiversity, and integrated methods of weed control. For this Special Issue, we welcome all types of articles, including original research, opinions, and reviews.
