Future Foods, Volume 3, June 2021
Food is essential to provide energy for human cellular metabolism, and is usually made from plants or animals. Beside plants and animals, other important food sources are made by microorganisms, typically products of fermentation (e.g bread, wine, beer, soy sauce, etc). Nowadays, because of the increasing environmental pollution, climate change and population growth, is becoming challenging to keep the food supply safe, nutritious and sustainable. Importantly, the development of the synthetic biology field enable the engineering of cells that can be used in food manufacturing.

As sea level rise drives saltwater farther inland, drinking water supplies of some coastal cities will be contaminated. This paper evaluates how climate change is shifting the location of ‘salt lines,’ the zone where coastal fresh water meets the ocean, and implications for drinking water management. It focuses on changes from climate, as opposed to water overuse or water quality mismanagement, and reviews recent literature along three dimensions. Firstly, the paper reviews regulations on salinity in drinking water.

Climate change has affected diverse spheres and its impact is being witnessed worldwide. Soil, the basis of human sustenance, is both directly and indirectly affected by climate change. Soil erosion, vegetation degradation and soil salinisation are becoming prevalent, causing a threat to future food security. Saline soils are found mainly in North and Central Asia, Africa and South America. Various factors such as excess irrigation and poor drainage, groundwater salinity, sea level rise and intrusion, irregular rainfall contribute to the process of soil salinisation.

Water is the fundamental natural resource that supports life, ecosystems and human society. Thus studying the water cycle is important for sustainable development. In the context of global climate change, a better understanding of the water cycle is needed. This study summarises current research and highlights future directions of water science from four perspectives: (i) the water cycle; (ii) hydrologic processes; (iii) coupled natural-social water systems; and (iv) integrated watershed management.

Droughts are significant drivers of land degradation, which in turn has adverse effects on resource-dependent rural populations and can potentially lead to livelihood losses and subsequent migration out of affected areas. Linkages between land degradation and migration are complex and not particularly well documented, as they occur within a larger context of multi-scale interactions of socio-economic, political, demographic, and environmental processes. Given these uncertainties, further research in this field is needed.
