Hydroponic Lettuce Cultivation Using Organic Nutrient Solution from Aerobic Digested Aquacultural Sludge
2021
The aim of this study was to demonstrate how aquacultural sludge can be processed and utilized as an organic nutrient solution (ONS) for hydroponic lettuce production. By using a previous developed method, approximately 80% of the processed sludge was reclaimed as a clear, nutrient-rich solution. The performance of the recovered nutrient solution on lettuce growth was assessed in a nutrient film hydroponic system. The results were compared to the results obtained using a conventional nutrient solution (CNS). Yield, fresh weight, water consumption, and nutrient and heavy metal content in leaf tissue were measured. In spite of a 16% lower average fresh weight obtained in ONS compared to the w…
Matproduksjon, mattrygghet og miljø - innspill om kunnskapsbehov til gjennomføringen av det grønne skiftet - Uttalelse fra hovedkomiteen i Vitenskaps…
2022
Denne rapporten er utarbeidet av Vitenskapskomiteen for mat og miljø (VKM), en uavhengig, tverrfaglig komité som utarbeider kunnskapsgrunnlag for den norske mat- og miljøforvaltningen på områdene matproduksjon, mattrygghet og biologisk mangfold. De siste tiårene har FNs klimapanel, Det internasjonale naturpanelet, Det internasjonale ressurspanelet og flere andre paneler og organisasjoner levert rapporter som dokumenterer at befolkningsvekst og menneskelig aktivitet fører med seg store og økende utfordringer på miljø-, klima- og ressursområdet. Endringer innen disse områdene påvirker matproduksjon, matsikkerhet, mattrygghet, folkehelse og naturverdier i alle deler av verden (UNEP, 2021). Sam…
Illegal Chinese gold mining in Amansie West, Ghana - an assessement of its impact and implications
2014
Master thesis in development management - University of Agder 2014 The thesis’ objective is to assess the impact of Chinese illegal miners in the Amansie West District in Ghana. The illegal mining sector is seen as having several negative effects, environmentally as well as socially and economically. The influx of some 20-50 000 Chinese miners into Ghana is found to increase these impacts. The Chinese illegal miners operate largely on farmland, which is bought from locals for the sum equivalent of approximately 6.5 years of farming income. This leads to a loss of long-term income for the farmer as well as the degradation of large land areas, which in the case of Amansie West is here estimat…
