Biodiversity and ecosystems

Biodiversity and ecosystems, encompassing the vast variety of life on Earth and the natural systems they inhabit, are fundamental to the Sustainable Development Goals (SDGs). Their importance is acknowledged explicitly in several SDGs due to their critical role in maintaining environmental balance and supporting human life and well-being.

SDG 14 (Life Below Water) and SDG 15 (Life on Land) are directly focused on the conservation and sustainable use of aquatic and terrestrial ecosystems, respectively. These goals recognize the intrinsic value of biodiversity and the vital services ecosystems provide, such as habitat for wildlife, carbon sequestration, and soil formation. The preservation and restoration of ecosystems like forests, wetlands, and coral reefs are essential for maintaining biodiversity, which in turn supports ecological resilience and the sustenance of human life.

The role of biodiversity and ecosystems in achieving SDG 2 (Zero Hunger) is significant. The variety of life forms, including plants, animals, and microorganisms, underpins agricultural productivity. Pollinators, soil organisms, and genetic diversity of crops are all crucial for food production and agricultural resilience. Ecosystems support agriculture not just in terms of crop yield but also in sustaining the natural resources like soil and water, upon which agriculture depends.

Similarly, SDG 6 (Clean Water and Sanitation) is closely tied to the health of ecosystems. Natural habitats such as forests and wetlands play a key role in filtering and purifying water, maintaining the water cycle, and regulating water flow. This natural filtration process is vital for providing clean drinking water and supporting sanitation systems.

Biodiversity and ecosystems are also crucial for SDG 3 (Good Health and Well-being). Natural environments regulate diseases by supporting a balance among species that, in turn, can control pest and disease outbreaks. Additionally, a vast number of medical discoveries, including medicines and treatments, have their origins in biological resources, underscoring the potential of biodiversity in contributing to human health and well-being.

Moreover, biodiversity and ecosystems play a significant role in addressing climate change, linking to SDG 13 (Climate Action). Ecosystems such as forests and oceans are major carbon sinks, absorbing and storing carbon dioxide from the atmosphere. Protecting and restoring these ecosystems are vital strategies for climate change mitigation. Additionally, healthy ecosystems provide crucial services for climate change adaptation, such as protecting against extreme weather events and helping communities adjust to changing environmental conditions.

However, achieving these goals requires addressing threats to biodiversity and ecosystems, such as habitat destruction, pollution, overfishing, and invasive species. It also involves balancing the needs of human development with environmental conservation, ensuring sustainable use of natural resources.

Biodiversity and ecosystems are integral to achieving multiple SDGs. Their conservation and sustainable use not only benefit the environment but are essential for food security, water purity, human health, and combating climate change. The protection and restoration of biodiversity and ecosystems are therefore crucial steps towards sustainable development and ensuring the well-being of current and future generations.

Conservation of biodiversity and ecosystem services in natural environments requires careful management choices. However, common methods of evaluating the impact of conservation interventions can have contextual shortcomings. Here, we make a call for counterfactual thinking—asking the question “what would have happened in the absence of an intervention?”—with the support of rigorous evaluation approaches and more thoughtful consideration of human dimensions and behavior.
The no-tillage system combining winter cover crops and crop rotation may increase the efficiency use of soil P and phosphate fertilizer. The objective of this study was to evaluate the effect of three decades of different soil management systems and winter cover crops on the fractions of P in a clayey Oxisol of Paraná State, Brazil. The bi-factorial experiment with three replicates was established in 1986. The main plots consisted of seven winter cover crops. In the subplots, two tillage systems were used: no-tillage and conventional tillage.

Soils host the vast majority of life on Earth including microorganisms and animals, and supporting all terrestrial vegetation. While soil organisms are pivotal for ecosystem functioning, the assemblages of different biota from a taxonomic and functional perspective, as well as how these different organisms interact, remains poorly known. We provide a brief overview of the taxonomic and functional diversity of all major groups of soil biota across different scales and organism sizes, ranging from viruses to prokaryotes and eukaryotes.

Background: Synthetic biology is an emerging multidisciplinary area of research with the potential to deliver various novel agrifood applications. Its long-term adoption and commercialisation will depend on the extent to which the public accept synthetic biology and its different applications. Scope and approach: A mapping review of existing research on public perceptions of, and attitudes towards, synthetic biology and its applications to agriculture and food production was conducted.

Manual chamber-based measurements of CO2 (and H2O) fluxes are important for understanding ecosystem carbon metabolism. Small opaque chambers can be used to measure leaf, stem and soil respiration. Larger transparent chambers can be used to measure net ecosystem exchange of CO2, and small jars often serve this purpose for laboratory incubations of soil and plant material. We developed an Android application (app), called Flux Puppy, to facilitate chamber-based flux measurements in the field and laboratory.

This microplastics special issue compiled by Trends in Analytical Chemistry supports many of the SDGs, namely SDGs 3 (good health and well-being), 9.5 (enhance scientific research), 12 (responsible consumption and production), 14 (life below water) and 15 (life on land).

For seventy years, mass plastic production and waste mismanagement have resulted in huge pollution of the environment, including the marine environment. The first mention of seafood contaminated by microplastics was recorded in the seventies, and to date numerous studies have been carried out on shellfish, fish and crustaceans. Based on an ad hoc corpus, the current review aims to report on the numerous practices and methodologies described so far.

To fight against the biodiversity loss and to take advantage of ecosystem services that nature can offer, urban planners integrate green spaces in urban projects. However to assess green spaces, attention is generally paid to local biodiversity (i.e. “in situ”)which concerns the plot on which buildings are constructed. The biodiversity impacted outside the construction site (i.e. “ex situ”)which concerns the extraction of materials, transportation and waste, is rarely associated to the project assessment.
