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.

The past decade has witnessed a burst of study regarding antibiotic resistance in the environment, mainly in areas under anthropogenic influence. Therefore, impacts of the contaminant resistome, that is, those related to human activities, are now recognized. However, a key issue refers to the risk of transmission of resistance to humans, for which a quantitative model is urgently needed. This opinion paper makes an overview of some risk-determinant variables and raises questions regarding research needs.

Agricultural Systems (Second Edition), Agroecology and Rural Innovation for Development, 2017, Pages 33-72

This book chapter addresses goals 11, 15, 12 and 13 by examining the ecological principles that provide a foundation for resilient and sustainable agriculture that supports rural livelihoods.
Maize growing under plastic

Critics claim that maize can cause unwanted environmental impacts. But supporters of the crop are able to show how by use of cover crops it can be grown responsibly, reducing or eliminating, for example, nutrient leaching and soil erosion. In south-west England, a Wessex Water project is using cover crops to protect and improve drinking water quality by working with growers whose farms surround boreholes and reservoirs that supply water for human consumption. Steps like this can contribute to SDG 6 to ensure sustainable management of water and SDG 12 to ensure sustainable production.

Methods in Stream Ecology: Third Edition, Volume 1, 20 February 2017

This book chapter advances SDG 14 by providing an overview of the methods for monitoring stream temperature, characterization of thermal profiles, and modeling approaches to stream temperature prediction. The development of spatially explicit predictive models provides a framework for simulating natural and anthropogenic effects on thermal regimes, which is integral for the sustainable management of freshwater systems.

Methods in Stream Ecology: Third Edition, Volume 1, 20 February 2017

This book chapter advances SDG 14 by outlining the use of behavioral observations, gut content and fecal analyses, morphological measurements, and stable isotopes for drawing inferences about the trophic ecology of stream fishes. These methods allow insights at the level of individuals, populations, communities, and entire food webs. Using multiple methods in concert provides a rich perspective on how dietary differences among fish species affect stream ecology.
Natural World Heritage Sites (NWHS), via their formal designation through the United Nations, are globally recognized as containing some of the Earth's most valuable natural assets. Understanding changes in their ecological condition is essential for their ongoing preservation. Here we use two newly available globally consistent data sets that assess changes in human pressure (Human Footprint) and forest loss (Global Forest Watch) over time across the global network of terrestrial NWHS.

The rapid global conversion of biodiverse landscapes to intensively managed arable fields may decrease microbial diversity and threaten the long-term fertility of native soils. Previous laboratory and experimental studies provide conflicting results: some have recorded declines in overall microbial diversity and certain beneficial microorganisms under intensified cultivation while others report no change (or even increased) diversity. However, few studies have been carried out in actual agricultural fields.
This book chapter addresses goals 3, 12, and 15 by exploring the ability of African medicinal spices and vegetables to tackle malignant diseases.

Carbon dioxide is becoming a valuable raw material for chemical industry
It is a sign of the maturity of the green and biobased chemicals sector that major producers and technology providers are making moves to join the entrepreneurs and start-ups that have been driving the technology forward. This positive trend supports the advancing of SDG 9 Industry, Innovation and Infrastructure, and SDG 7 Affordable and Clean Energy.
