How robust is water quality determination with optical measurements for highly polluted agricultural waters? por Uwera, Honorine

“…Absorbance and excitation wavelength at 240-600 nm and emission wavelengths at 211-260 nm were used to measure SS and DOC in the water samples. …”

Urban Farming: Production comparison of Basil and Oak Leaf lettuce in two hydroponic growing systems : an industrial collaborated study in Sweden por Malik, Omer Hafeez

“…The use of chemicals and fertilizers to increase food production from the same land area is posing serious risks to human health and environment by increasing the emission of greenhouse gases. In this intricate scenario, indoor urban farming is gaining popularity because of many coupled advantages and benefits. …”

Low scores, high standards- a case study on Coop’s sustainability declaration por Malthed, Caroline, Wrenfelt, Tuva

“…Food production has the single biggest impact on global environmental changes, since 21-37% of the world's total greenhouse gas emissions comes from the agricultural systems. Sweden is highly dependent on imports for its food supply which makes it sensitive for external pressures and global events. …”

Smallholder farmers and biofuel por Moges, Kassaye Tekola

“…Globally biofuels have increasingly been considered as an alternative energy source that could help to reduce green house gas emissions for combating climate change. It is also believed that biofuels have a variety of other potential benefits such as promoting rural development and employment generation. …”

Assessing the importance of freshwater tributary systems for the recruitment of Eurasian Perch (Perca fluviatilis) in Baltic Sea Coastal Ecosystems por Wastie, Joe

“…Otoliths were removed from perch specimens and analysed for strontium (Sr) and calcium (Ca) ratios via particle induced x-ray emissions techniques (μPIXE). In order to determine birth origin of the coastal perch in the study areas, a freshwater baseline was established using other freshwater recruited coastal perch, as well as lake perch specimens. …”

Improving the existing farming systems toward a climate smart agriculture in Musanze district of Rwanda por Uzamukunda, Stephanie

“…Its implementation will help to reach food security, to adapt to climate change while trying to reduce greenhouse gas emission. For this reason, it requires governmental commitment towards farmers’ needs and involving them in decision making, but also to change from the only economic focus to the other aspects of sustainability: social and environment in order to have enjoyable life both for current and the future generations.…”
