Spatial Frameworks For Robust Estimation Of Yield Gaps, Juan I. Rattalino Edreira, José F. Andrade, Kenneth G. Cassman, Martin K. Ittersum, Marloes P. Van Loon, Patricio Grassini Sep 2021

Spatial Frameworks For Robust Estimation Of Yield Gaps, Juan I. Rattalino Edreira, José F. Andrade, Kenneth G. Cassman, Martin K. Ittersum, Marloes P. Van Loon, Patricio Grassini

Department of Agronomy and Horticulture: Faculty Publications

Food security interventions and policies need reliable estimates of crop production and the scope to enhance production on existing cropland. Here we assess the performance of two widely used ‘top-down’ gridded frameworks (Global Agro-ecological Zones and Agricultural Model Intercomparison and Improvement Project) versus an alternative ‘bottom-up’ approach (Global Yield Gap Atlas). The Global Yield Gap Atlas estimates extra production potential locally for a number of sites representing major breadbaskets and then upscales the results to larger spatial scales. We find that estimates from top-down frameworks are alarmingly unlikely, with estimated potential production being lower than current farm production at some …

Effects Of Different Extraction Solvents On The Extractive Removal And Properties Of Oil Palm Empty-Fruit Bunch Cellulosic Nanofibers, Achmad Solikhin, Yusuf Sudo Hadi, Muh Yusram Massijaya, Siti Nikmatin Sep 2021

Effects Of Different Extraction Solvents On The Extractive Removal And Properties Of Oil Palm Empty-Fruit Bunch Cellulosic Nanofibers, Achmad Solikhin, Yusuf Sudo Hadi, Muh Yusram Massijaya, Siti Nikmatin

Makara Journal of Science

In this study, the effect of different extraction solvents on the isolation and properties of cellulosic nanofibers (CNFs) were investigated. The unextracted and different solvent-extracted CNFs formed horn-like features and irregularly aggregated nanofibers after oven drying. Scanning electron microscopy at 10000× magnification revealed the smooth external surfaces of all extracted CNFs; this finding is attributed to the limited deposition of amorphous lignocellulosic components on the fibers. All resultant CNF solutions revealed aggregation, with a particle size distribution and zeta average of 21.39–513.00 nm and 162.26–342.13 nm, respectively. Extraction with different solvents and chemical treatment yielded CNF solutions with good transparency. …

Allowing Consumers To Choose Quantities In Choice Experiments Impacts Consumer Choice, Rationality, And Willingness-To-Pay Estimates, Elliott James Dennis Sep 2021

Allowing Consumers To Choose Quantities In Choice Experiments Impacts Consumer Choice, Rationality, And Willingness-To-Pay Estimates, Elliott James Dennis

Cornhusker Economics

Choice experiments are frequently used by industry and academic researchers to examine existing and hypothetical products. These experiments generally fix the quantity purchased and allow product attributes to vary. New choice experiments have explored allowing quantity to be a flexible choice attribute. In a recently published paper, we explored the potential differences and similarities between these two choice experiment frameworks. To illustrate these comparisons and any relative improvements by using a quantity choice framework, we used a between-subject design that assessed U.S. meat preferences.
