Reducing Food Scarcity: The Benefits Of Urban Farming, S.A. Claudell, Emilio Mejia

Journal of Nonprofit Innovation

Urban farming can enhance the lives of communities and help reduce food scarcity. This paper presents a conceptual prototype of an efficient urban farming community that can be scaled for a single apartment building or an entire community across all global geoeconomics regions, including densely populated cities and rural, developing towns and communities. When deployed in coordination with smart crop choices, local farm support, and efficient transportation then the result isn’t just sustainability, but also increasing fresh produce accessibility, optimizing nutritional value, eliminating the use of ‘forever chemicals’, reducing transportation costs, and fostering global environmental benefits.

Testing The Potential Of Novel Grain Crop Cultivation In Rural Malawi During The Dry Season Through Irrigation And Soil Modification, Jessica Truman

Undergraduate Honors Theses

This research project studied the germination and growth rates of oat and quinoa crops in Mtalimanja, Malawi. This project was part of a larger effort by General Mills and Brigham Young University researchers to increase the diversity and nutrient content of crops in impoverished countries worldwide. It was conducted from May to August 2017 during Malawi’s dry season. Tetraploid oats and quinoa, both modified to increase the protein content of harvested grains, were planted under three different soil conditions: unamended soil, soil mixed with composted chicken litter, and soil with surface-applied granular fertilizer. The research plots were watered daily except …

Production Of The Edible Mushroom (Agaricus Sp.) Under Laboratory Conditions For Their Multiplication In Different Culture Media, Mercedes Victoria Galeón Alcón

Theses and Dissertations

Edible mushroom production has two different stages: the vegetative stage and the fruiting stage. The vegetative phase is performed in a biotechnology laboratory and covers the technique for obtaining “spawns”, which parameters include the multiplication and reproduction of the mycelium. The fruiting phase begins with the appearance of edible mushrooms and includes everything that occurs outside the laboratory. In our country, production of edible mushrooms is limited and generally unknown. So, in this study, the vegetative phase was divided into two stages and conducted in the laboratory. Stage 1: We inoculated spores and implants of the edible mushroom species Agaricus …

Energy Value In Llamas (Lama Glama) Fed With Alfalfa Hay (Modicago Sativa) And Barley (Hordeum Vulgare) For Apparent Digestibility In Vivo In The National Camelid Germplasm Bank (Ceac), Edwin Gonzalo Ugarte Huanca

Theses and Dissertations

In this experiment, we used four male llamas that were three to four years of age from the Khara race. They were divided into two ad libitum feeding groups. The digestible energy (ED) was determined using samples that were sent to the laboratory. These samples were derived from a conventional in vivo assay using the method of total fecal collection in order to determine the difference between energy consumed and energy excreted. Metabolizable energy was calculated by deducting digestible energy, energy loss in the urine and energy loss in the gases (methane). Urinary energy was determined through the measurement of …

Agronomical Evaluation Of Six Species Of Forage Grass Tolerant To Salinity In The Tamborada Region, Bladimir Vargas Rojas

Theses and Dissertations

Six forage grass species from the United States were evaluated for salinity tolerance and growth performance. A randomized block design was used with six repetitions of five furrows each to maintain experimental consistency. The study was conducted in the Tamborada region of Cochabamba, Bolivia from December 2003 through June 2004. Results indicated that significant differences exist between species (Pr<0.01). The species Elymus cinereus and Agropyron elongatum demonstrated the best performance regarding plant height, achieving heights of 35.4 cm and 32.7 cm respectively. Festuca arundinacea and Agropyron elongatum obtained larger percent coverage than the other species with 79.59% and 76.53% respectively. These species also exceed the others in production of green forage (1500.00 kg/ha and 13985.80 kg/ha) as well as in production of dry matter (5000.70 kg/ha and 4862.85 kg/ha). They are recommended for production in the region of Tamborada, Cochabamba, Bolivia.

Development Of A Process Of Addition Of Tricalcium Phosphate From Burnt Phosphate Rock In Feed For Animal Nutrition, Luis Fernando Nogales Grágeda

Theses and Dissertations

This study took place in Bolivia with the purpose of using thermally treated Capinota phosphate rock as a phosphorous supplement in balanced feed diets. The objective was to produce a natural phosphate substance that would be more easily accessible to the local population than commercial feed supplements. An additional objective of this study was to increase the availability of the low-fluoride phosphorous. The biological assays indicated that the diet with the added burned phosphoric rock produced similar yields to those using a commercial feed supplement (dicalcium phosphate). This indicates that the locally manufactured product, by partial acidification, can compete with …

Evaluation Of Agronomic Performance Of Forage Grasses In Tiahuanaco, Justiniano Mamani Condori

Theses and Dissertations

Most families in the area of Tiahuanaco, Bolivia participate in livestock production, mainly cattle breeding. The primary feed sources for livestock in this area are native grasses, barley, and, to a smaller degree, oats. These grasses have low yield because of climate and soil conditions. This area does not have enough forage, especially during the dry season, and the animals are not regularly fed during the year. Consequently, animal production is low. This research was conducted during 2001 and 2002 at the Bolivian Catholic University campus, Farmer’s Academic Unit of Tiahuanaco, Ingavi Province, La Paz, Bolivia. Study site locations were …
