Food Biodiversity Challenges From a Global Perspective Last Updated on 2014-07-25 14:03:15 Food collection or gathering has been an important part of human endeavors towards establishing civilization across the long history of human evolution. Humans have demonstrated their ingenuity in identifying and locating new and novel food sources located in their immediate surrounding and during their migration across the planet. Humans have become more successful than other species because of their better foraging abilities and coordinated group work in identifying and locating novel food sources over time. This trial and error approach has enabled humans over time to identify suitable food sources from their local environments. Over time, humans have identified more species that are edible or could be made edible using primitive to modern day recipes and cooking techniques. These long years of trial and errors have generated a wide range of food sources for... More »
Vermicompost Last Updated on 2014-06-19 16:05:40 Vermicomposting, which is composting using worms, can be a faster alternative for organic waste treatment, with the added advantage of better quality fertilizer with nutrients in the slow-release form. Vermicomposting also adds valuable soil microbes into compost and digestive fluids of worms can also be beneficial. Vermicomposting is the breakdown of organic material that, in contrast to microbial composting, involves the joint action of different species of earthworms (not all earthworms are composting worms) and microorganisms and does not involve a thermophilic (i.e., high heat) stage. Because the matrix contains many different organisms, this can be considered as an anthropogenic ecosystem. As the agents of turning, fragmentation and aeration, the worms consume organic wastes such as food waste, animal wastes and sewage sludge to produce a soil conditioner. Vermicomposting may... More »
Biomass Crop Assistance Program (BCAP): Status and Issues Last Updated on 2014-06-11 15:55:19 Summary The Food, Conservation, and Energy Act of 2008 (P.L. 110-246, 2008 Farm Bill) created the Biomass Crop Assistance Program (BCAP). The two main purposes of BCAP are: (1) to support the establishment and production of eligible crops for conversion to bioenergy in selected areas: and (2) to assist agricultural and forest land owners and operators with collection, harvest, storage, and transportation of eligible material for use in a biomass conversion facility. BCAP is intended to assist with the bioenergy industry’s hurdle of continuous biomass availability. The U.S. Department of Agriculture’s (USDA) Farm Service Agency (FSA) implemented one portion of BCAP—the Collection, Harvest, Storage, and Transportation (CHST) matching payment program—on June 11, 2009, through a Notice of Funds Availability in the Federal Register. The partial implementation... More »
Wheat Last Updated on 2014-05-21 15:51:12 Wheat is any of a number of species of the genus Triticum within the grass family of Poaceae. Wheat is an important grain food crop supplying the second highest caloric intake for humans, closely behind rice. Wheat is used to produce flour for bread, pasta, couscous and other foods. However, wheat generally consumes large amounts of nitrate and other fertilizers, so that the outcome of widespread wheat farming is often associated with extensive water pollution impacts, expecially related to nitrate laden runoff. Wheat is one of the earliest cultivated crops, and has a clear association with the emergence of sedentary agriculture around twelve millennia ago. Products Made From Wheat: 1.  Crossaint; 2.  Wheat Flour; 3. Noodles; 4. Wheat Dalia; 5.  Sewai; 6.  Refined Wheat Flour; 7.  Common Brown Bread; 8. ... More »
Chesapeake Bay oyster depletion Last Updated on 2013-10-05 01:13:04 Chesapeake Bay oyster depletion has occurred significantly in the period 1960 to 2010. This depletion is caused by a number of factors, including water quality, disease and over harvesting. The native oyster to the Chesapeake Bay and all Atlantic Coast regions is the American or Eastern Oyster Crassostrea virginica. The Bay's ecological conditions are ideal for  oysters, and the oyster fishery was at one time the Bay's most commercially viable enterprises. However, in the last fifty years the oyster population has been devastated. Maryland once had roughly 200,000 acres of oyster reefs; in 2010 it has about 36,000 such reefs. In pre-colonial times, oysters filtered the entirety of the Chesapeake Bay in approximately 3.3 days; by 1988 this time had increased to 325 days. The oyster harvest's gross value has decreased 88% from 1982 to 2007. Today there are fewer... More »
