Greater recognition is being given to the need for building sustainable and resilient urban food ecosystems . In Figure 1 we have attempted to illustrate how key concepts of agroecology can stimulate the food systems thinking in a city-region food system context.As highlighted above, the focus on food systems in the discussion about agroecology demands …

A number of strategies to incentivize wildlife-friendly gardening activities already exist
UA systems may contribute to the reduction of impervious surfaces in urban landscapes, thus increasing the drainage and infiltration potential of precipitation.As mentioned in the Urban agricultural systems and biodiversity provision section, it is important to understand that not all biodiversity is necessarily “good” biodiversity, and there may be a number of disservices that come from …
Humulus and Cannabis are monotypic sister genera in the family Cannabaceae
The activities of several housekeeping genes were also tested. A relatively modest increase in levels of histone H2A and beta tubulin expression in glands compared to leaves was detected. The increase in expression levels of these latter two genes might reflect a combination of the heightened metabolic activity and the unique cellular structure of glandular trichomes. …

The linkage between water and food production was estimated in two different ways
This type of disjointed management leaves policy makers ill-equipped to provide resilient management strategies. Thus, the success of using the nexus concept to improve food, energy, and water systems will likely depend on how it incorporates issues surrounding resource governance , including how governance and the discourse of securitization become a way to legitimize political …

Container-based toilets separated urine and feces into different compartments
Several other plant-growth-promoting bacteria, including Bacillus siamensis, Bacillus megaterium, Bacillus subtilis, and Bacillus cereus, had relatively higher IAA yields at temperatures of 2–135 ◦C and pH 7–8. Three different bacteria isolated from therhizosphere of Stevia rebaudiana also exhibited greater production of IAA at a pH range of 6–9 and a temperature of 35 ◦C to …

Long established subsistence activities were abandoned in favor of menial wage labor
The survey results also indicate that the program contributed to the alumni’s efforts by providing skills, knowledge, and confidence as well as confirming and shaping values and career goals. Blending hands-on and classroom education on a wide variety of food systems topics, combined with the Apprenticeship’s residential structure, appears to play a major role in …
Root morphology and metabolism are affected by abiotic and biotic factors
On the following days however, when exchange sites at the lower part of the stem were assumingly saturated and the amount of radio-Sr in the feed declined due to solution topping and dilution, “wash out” of radio-Sr was demonstrated by negative rates at the lower stem detectors with positive rates at the upper parts indicating …

The RYMV open reading frame 2 was highly expressed in transgenic rice
Viral resistance using RNA homology-dependent silencing has been successfully engineered into many plant systems. Single or multiple viral-derived transgenes can be expressed in plants leading to RNA homology-dependent silencing and subsequent viral resistance. The use of this transgenic technology may be particularly effective in thwarting viral diseases where little or no genetic resistance has been …

Current manufacturing systems have already produced over 200 tools and parts in the ISS
However, recent growth strategies in this industry suggest that the private sector have leaned towards M&A-focused approaches4 rather than in-house research initiatives. The previous decade of the private sector was composed mainly of NewSpace companies developing end products and technologies for organic growth.The rise of space-focused investment funds and venture capital arms of traditional aerospace companies not …
