Generating plausible crop distribution and performance maps for Sub-Saharan Africa using a spatially disaggregated data fusion and optimization approach por You, Liangzhi, Wood, Stanley, Wood-Sichra, Ulrike

“…Apart from the empirical challenge of applying the approach across many countries, the application includes three significant model improvements, namely (1) the ability to cope with production data sources that provided different degrees of spatial disaggregation for different crops within a single country; (2) the inclusion of a digital map of irrigation intensity as a new input layer; and (3) increased disaggregation of rainfed production systems. …”

The temperature-dependent duration of development and parasitism of three cereal aphid parasitoids, aphidius ervi, a-rhopalosiphi, and praon volucre por Sigsgaard, Lene

“…A physiological model described temperature‐dependent development over the full temperature range, whereas a linear model was fitted for data above 8 °C and used to estimate the lower temperature thresholds and day‐degrees (° D) required for development. The thresholds for A. ervi were 2.2 °C for egg‐mummy development and 6.6 °C for mummy‐adult development, those for A. rhopalosiphi were 4.5 °C and 7.2 °C, and those for P. volucre were 3.8 °C and 5.5 °C. …”

Varietal Interventions and Their Significance in Rice-Based Cropping Systems of Drought-Prone Ecologies in Odisha por Nayak, Swati, Nath, Anirban, Hossain, S.K. Mosharaf, Singh, Varsa, Mohapatra, Subhasmita

“…Out of the last 41 episodes of natural calamities that hit the state in the last 50 years, 19 of these were severe droughts. This is aggravated by the fact that the state is dependent mostly on rainfed systems and only 38% of the cultivated area has coverage or access to some degree of irrigation. …”
