Rice Bowl
The breadbasket of a country or of a region is an area which, because of the richness of the soil and/or advantageous climate, produces large quantities of wheat or other grain. Rice bowl is a similar term used to refer to Southeast Asia; and California's Salinas Valley is sometimes referred to as America’s salad bowl. Such regions may be the subject of fierce political disputes, which may even escalate into full military conflicts. Breadbaskets have become important within the global food system by concentrating global food-production in a small number of countries and, in countries such as India, in small geographic regions. As climate change increases weather variability around the world, the likelihood of multiple breadbaskets failing at a time increases dramatically. The 2022 food crises has been in part facilitated by a series of failures in key breadbasket regions, and the 2022 Russian invasion of Ukraine has created significant potential disruption of the respectiv ...

Soil
Soil, also commonly referred to as earth or dirt, is a mixture of organic matter, minerals, gases, liquids, and organisms that together support life. Some scientific definitions distinguish ''dirt'' from ''soil'' by restricting the former term specifically to displaced soil. Soil consists of a solid phase of minerals and organic matter (the soil matrix), as well as a porous phase that holds gases (the soil atmosphere) and water (the soil solution). Accordingly, soil is a three-state system of solids, liquids, and gases. Soil is a product of several factors: the influence of climate, relief (elevation, orientation, and slope of terrain), organisms, and the soil's parent materials (original minerals) interacting over time. It continually undergoes development by way of numerous physical, chemical and biological processes, which include weathering with associated erosion. Given its complexity and strong internal connectedness, soil ecologists regard soil as an ecosystem. Most ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
