Aim To identify priority areas for in situ conservation and collection of germplasm ex backup crop wild relative (CWR) diversity the Southern African Development Community (SADC) region as part an action plan use region's important CWR diversity. Location SADC region. Methods Diversity, gap climate change analyses at species ecogeographic levels were undertaken 113 regional taxa. Results hotspo...

s of papers 47 follow manner. Rules for Animal Feeding Operations have been recently enforced and will require adoption of appropriate Best Management Practices (BMP’s), which includes Nutrient Management Planning for all operations where animals are raised in confinement according to regulatory definition. Nutrient management is necessary for agricultural production systems to protect air, soi...

Background: The EU-project Flourish intends to establish an autonomously operating precision farming system based on the interaction between unmanned ground vehicles (UGVs) and unmanned aerial vehicles (UAVs). For effective mission planning and site-specific ground intervention by the UGV, the growth, mineral nutrition, weed, and health status of the crop field must be evaluated efficiently. In...

In agricultural harvesting processes, the infield logistics of transporting the crop from the harvesters' tanks to a street transporter at the field border with an unloading vehicle is challenging. The harvesters have to be unloaded while driving and in time to prevent the loss of expensive process time. The path planning for the unloading vehicle has to consider the unharvested area as a dynam...

We examine the impact of current and future climate on crop mixes over space in the US. We find using historical data that temperature and precipitation are among the causal factors for shits in crop production location and mixes, with some crops being more sensitive than others. In particular, we find that when temperature rises, cotton, rice, sorghum and winter wheat are more likely to be cho...

A simulation and optimization model was developed and applied to an irrigated area in Delta, Utah to optimize the economic benefit, simulate the water demand, and search the related crop area percentages with specified water supply and planted area constraints. The user interface model begins with the weather generation submodel, which produces daily weather data, which is based on long-term mo...

Estimation of specific crop and acreage plays a vital role in the field of crop planning, monitoring, crop condition, yield forecasting and acreage estimation. There have been several studies conducted to classify the crops at continental to the regional level, but still, work is needed to map small area covered by different crops using Remote Sensing technology. The main objective of the prese...

Satellite based earth observation (EO) platforms have proved capability to spatio-temporally monitor changes on the earth's surface. Long term satellite missions have provided huge repository of optical remote sensing datasets, and United States Geological Survey (USGS) Landsat program is one of the oldest sources of optical EO datasets. This historical and near real time EO archive is a rich s...
