Climate change

Each year, the Food and Agriculture Organization of the United Nations (FAO) celebrates World Food Day on October 16th to commemorate is founding in 1945. World Food Day 2020 is calling for global solidarity to help all populations to recover from the crisis, and to make food systems more resilient and robust so they can withstand increasing volatility and climate shocks, deliver affordable and sustainable healthy diets for all, and decent livelihoods for food system workers. In support of this years theme - 'Grow, Nourish, Sustain. Together' - Elsevier presents a curated, open access collection of 40 journal articles and book chapters focussed on increasing food security and sustainability.

After water, concrete is the second most used material in the world. Using life cycle assessments, concrete has typically been found to be 80% of a residential building by weight. Cement production consumes large amounts of energy, motivating a search for sustainable alternatives. Rice husk ash produced in controlled combustion has been found to be a viable replacement for cement. Renewable and sustainable, rice husks have the potential to produce energy while yielding an ash product for use in concrete.
Ecology plays a central role in the management and conservation of ecosystems. However, as coral restoration emerges as an increasingly popular method of confronting the global decline of tropical coral reefs, an ecological basis to guide restoration remains under-developed. Here, we examine potential contributions that trophic ecology can make to reef restoration efforts. To do so, we conducted a comprehensive review of 519 peer-reviewed restoration studies from the past thirty years.
CeO2 shows unique catalytic properties by an acid–base bifunctionality as well as redox properties. The acid–base bifunctional properties of CeO2 have been applied to the non-reductive CO2 conversion with alcohols such as dimethyl carbonate (DMC) synthesis from CO2 and methanol. CeO2 shows very high selectivity to DMC; however, the yield of DMC is strongly limited by the equilibrium. The combination of the synthesis of organic carbonates from CO2 and corresponding alcohols with suitable H2O removal methods can enhance the yield of the organic carbonates beyond the equilibrium limitation.
Manufacturing challenges are anticipated to become worse in the coming decades owing to global material and energy constraints combined with environmental issues associated with conventional processes. Addressing these difficulties calls for a significant amount of research to be conducted to establish robust new technologies that are cost-effective and energy efficient, while at the same time minimizing environmental pollution.

Solar light-driven water splitting provides a promising way to store and use abundant solar energy in the form of gaseous hydrogen which is the cleanest chemical fuel for mankind; therefore this field has been attracting increasing attention over the past decades.
Climate change requires joint actions between government and local actors. Understanding the perception of people and communities is critical for designing climate change adaptation strategies. Those most affected by climate change are populations in coastal regions that face extreme weather events and sea-level increases. In this article, geospatial perception of climate change is identified, and the research parameters are quantified.
Tillage is the most common agricultural practice dating back to the origin of agriculture. In recent decades, no-tillage (NT) has been introduced to improve soil and water quality. However, changes in soil properties resulting from long-term NT can increase losses of dissolved phosphorus, nitrate and some classes of pesticides, and NT effect on nitrous oxide (N2O) emission remains controversial. Complementary management that enhances the overall environmental benefits of NT is therefore crucial.
Agriculture consumes huge amounts of water in China and is profoundly affected by climate change. This study projects the agricultural water use towards 2030 under the climate change mitigation target at the provincial level in China by linking a computable general equilibrium (CGE) model and a regression model. By solving the endogeneities amongst agricultural water use, output and climate factors, we explore how these variables affect water use and further predict future trends through soft-link with the IMED|CGE model.
This special issue explores the influence that insects and other invertebrates have on ecosystem services and the Sustainable Development Goals (SDGs), and makes a case for insect science to promote a sustainability science approach.
