The biophysical properties of a crop are good indicator potential stress conditions. However, these visible cannot indicate areas exhibiting non-visible stress, e.g., early water or nutrient stress. In this research, maize including canopy height and Leaf Area Index (LAI), estimated using drone-based RGB images, were used to identify stressed in the farm. First, APSIM process-based model was si...

background and objectives: over the last decade, climate change has been one of the most challenging issues in the scientific papers. studying the impacts of climate change on crop productivity at regional scale will depend on the right estimate of future climate. this estimation is being implemented by climate models and most of them by general circulation models (gcms). this study aims at pre...

Extreme weather events cause considerable damage to the livelihoods of smallholder farmers globally. Whilst index insurance can help cope with financial consequences extreme weather, a major challenge for is basis risk, where payouts correlate poorly actual crop losses. We analyse what extent use simulation models and phenology monitoring reduce risk in insurance. Using biophysical process-base...

One of the main drivers deforestation in Zambia is expansion agricultural land for increasing production areas and shift cultivation due to poor crop management practices. Land was also echoed by farmers Northwestern province as they aim increase yield via expansion. It therefore important understand possible associated socio-ecological trade-offs extensification identify pathways improve ecosy...

El cambio climático (CC) afecta las condiciones meteorológicas actuales y repercute negativamente en el rendimiento de maíz, particularmente temporal. Para estimar los efectos del CC la productividad, se han utilizado modelos simulación crecimiento bajo diferentes escenarios climático. En este artículo hace una revisión sobre implementados globalmente, durante periodo 2006 a 2019; través, Scopu...

This study purposed to evaluate the impact of climate change on green gram yield, biomass and days maturity under baseline future scenarios in Kitui County, Kenya. A field experiment was conducted during March–April–May (MAM) October–November–December (OND) planting seasons 2018 2019 South Eastern Kenya University (SEKU) farm. Data soil physical chemical properties, daily data rainfall, maximum...

Information on soil erosion and related sedimentation processes are very important for natural resource management sustainable farming. Plenty of models available studying but only a few suitable dynamic assessments at the field-scale. To date, there no field-scale considering complex agricultural systems simulation erosion. We conducted review 51 different evaluated based their representation ...

Drought is an enduring abiotic constraint to stable and consistent maize productivity under climate change, especially for low rainfall regions with limited irrigation. One adaptation severe drought using drought-tolerant (DT) hybrids. Here, we characterize differences between conventional DT hybrids in terms of yield water-use efficiency conditions at a regional scale the Texas High Plains (TH...
