A gap analysis modeling framework to prioritize collecting for ex situ conservation of crop landraces by Ramírez Villegas, Julián Armando, Khoury, Colin K., Achicanoy Estrella, Harold Armando, Mendez Alzate, Andres Camilo, Sosa, Chrystian C., Debouck, Daniel G., Kehel, Zakaria, Guarino, Luigi

“…The degree of representation of crop landrace diversity in ex situ conservation is poorly understood, partly due to a lack of methods that can negotiate both the anthropogenic and environmental determinants of their geographic distributions. Here we describe a novel spatial modeling and ex situ conservation gap analysis modeling framework for crop landraces, using common bean (Phaseolus vulgaris L.) as a case study. …”

Model Comparison and Quantification of Nitrous Oxide Emission and Mitigation Potential from Maize and Wheat Fields at a Global Scale by Tesfaye, Kindie, Takele, Robel, Sapkota, Tek Bahadur, Khatri-Chhetri, Arun, Solomon, Dawit, Stirling, Clare, Albanito, Fabrizio

“…N2O emission from four models (CCAFS-MOT, IPCC Tier-I, IPCC Tier-II and Tropical N2O) using a standard gridded dataset from global maize and wheat fields were compared and their performance evaluated using measured N2O emission data points (777 globally distributed datapoints). The models were used to quantify spatially disaggregated N2O emission and mitigation potential from maize and wheat fields globally and the values were compared. …”

Assessment of water allocations using remote sensing and GIS modeling for Indus Basin, Pakistan by Cheema, Muhammad Jehanzeb Masud, Bakhsh, Allah, Mahmood, Talha, Liaqat, Muhammad Usman

“…Three years were selected for the study and two representative canal commands (Lower Chenab and Muzaffargarh Canal) were selected for detailed analysis and ground truthing. Spatially distributed maps of land use, crop water use, groundwater use and quality, soil and water salinity, and crop yields at a pixel resolution of 250 m (6.25 ha) were prepared and then verified by field surveys. …”

Remote training on updating ENACTS datasets with MALI-METEO by Faniriantsoa, Rija, List, Geneva

“…However, in many places, stations are sparse, declining in number, and unevenly distributed. By integrating observations with grided satellite data, ENACTS overcomes issues of data scarcity and poor quality, and introduces quality-assessed, spatially and temporally complete data services into national meteorological agencies. …”

Reducing uncertainty in nitrogen budgets for African livestock systems by Rufino, Mariana C., Brandt, P., Herrero, Mario, Butterbach-Bahl, Klaus

“…Livestock densities are usually modelled because of the lack of observational spatial data. Even though feed availability and quality varies across seasons, most studies use constant livestock excretion rates, and excreta are usually assumed to be uniformly distributed onto the land. …”

Incorporating scale dependence in disease burden estimates: The case of human African trypanosomiasis in Uganda by Hackett, F., Berrang-Ford, Lea, Fèvre, Eric M., Simarro, P.P.

“…However, most DALY estimates have been calculated as national totals. We mapped spatial variation in the burden of human African trypanosomiasis (HAT) in Uganda for the years 2000–2009. …”
