Market studies in Ghana have revealed a potential for composted or cocomposted fecal matter as nutrient source inputs for agricultural production. To increase the marketability of such products, high nutrient value and easier handling/transporting options are among the significant factors which drive demand. Pelletization is seen as a potentially interesting option to address these challenges. To preserve form stability of the pellet products, the addition of a binding material during the pelletization process is crucial. In Ghana, water, beeswax, clay, and cassava starch have been identified as locally available binding materials. A comparative assessment of these materials as a premier binder suitable for pelletization was performed based on predefined criteria. Quantitative criteria considered included the total amounts available, the seasonal variation during the year and cost. Qualitative criteria such as handling and storage conditions, ease of use during pelletization, and the binding ability were also evaluated. Based on this assessment, clay and cassava-based starch were selected as the most promising binding agents. Currently, clay is abundant in Ghana and this may suggest a guarantee for consistent and stable supply over coming years. However, from the perspective of cassava-based starch, this situation depicts limited production of starch and competition on the local markets.

Satellites have generated extensive data of remote sensing reflectance spectra (Rrs( )) covering diverse water classes or types across global waters. Spectral classification of satellite Rrs( ) data allows for the distinguishing and grouping of waters with characteristic bio-optical/biogeochemical features that may influence the productivity of a given water body. This study reports new satellite water class products (Level-2 and Level-3) from the Visible Infrared Imaging Radiometer Suite (VIIRS). We developed and implemented a hyperspectral scheme that accounts for the Rrs( ) spectral shapes and globally resolves oceanic, coastal, and inland waters into 23 water classes. We characterized the light absorption and scattering coefficients, chlorophyll-a concentration, diffuse attenuation coefficient, and suspended particulate matter for individual water classes. It is shown that the water classes are separable by their distinct bio-optical and biogeochemical properties. Furthermore, validation result suggests that the VIIRS water class products are accurate globally. Finally, we examined the spatial and temporal variability of the water classes in case studies for a demonstration of applications. The water class data in open oceans reveal that the subtropical ocean gyres have experienced dramatic expansion over the last decade. In addition, the water class data appear to be a valuable (and qualitative) indicator for water quality in coastal and inland waters with compelling evidence. We stress that this new satellite product is an excellent addition to the aquatic science database, despite the need for continuous improvement toward perfection.
