Modelling the Spatio‐Temporal Effects of Water Level Control in an Agricultural Collector Ditch Network

Irrigation and Drainage, EarlyView.
ABSTRACT The study focused on modelling open channel flow in an agricultural ditch network. The objectives were (1) to set up a computational tool to explore the hydraulic impacts of water level control in a collector ditch network and (2) to test the effects of damming height and ditch flow resistance on the water level and its relation to field ...

Climate and political effects on agriculture: Empirical evidence from SSA

International Studies of Economics, EarlyView.
Abstract The most of Sub‐Saharan African (SSA) countries have been affected by climate change and food insecurity problems due to the reduction of production and productivity of cereal crops in the continent. The purpose of this research was to examine the short‐run and long‐run effects of climate change on agricultural productivity in 24 selected SSA ...

Evaluation of Minnesota Phosphorus Loss Index performance

Journal of Environmental Quality, EarlyView.
Abstract Supported by the National Phosphorus (P) Research Project led by Dr. Andrew Sharpley, Minnesota developed its statewide P‐Index, the Minnesota P Loss Index (MNPI), to manage critical source areas of agricultural P. The MNPI has remained unchanged since its last revision in 2006.

Evaluating the potential for snowmelt phosphorus losses from perennial forage crops

Journal of Environmental Quality, EarlyView.
Abstract In cold regions, there is concern that losses of P with snowmelt runoff following freeze and thaw of vegetation may be greater from perennial forages relative to annual crops. We evaluate the drivers of P losses with snowmelt runoff over a network of field‐scale small watersheds in Manitoba, Canada, following annual crops (59 site‐years ...

Enablers and barriers to rotavirus vaccine coverage in Assam, India- A qualitative study

Vaccine: X
Background: Estimates suggest that 78,000 children died due to rotavirus gastroenteritis annually between 2011 and 2013 in India. The north eastern state of Assam reported 38.4% pediatric diarrheal admissions testing positive for rotavirus.

Integrating livestock and cropping systems: Interseeding cereal rye into corn for grazing

Journal of Environmental Quality, EarlyView.
Abstract Interseeding annual forages into growing corn may be an alternative for both cover and grazing in temperate regions of the United States. A 4‐year experiment evaluated the effect of interseeding cereal rye (Secale cereale) into corn for grazing after harvest on corn grain, forage biomass yield and quality, soil health, and estimated spatial ...

Testing Wisconsin P index assessments across cropping systems

Journal of Environmental Quality, EarlyView.
Abstract Managing agricultural runoff phosphorus (P) often requires understanding management effects on both dissolved P (DP) and particulate (sediment‐bound) P (PP). The Wisconsin P index (WPI) allows producers to assess land management effects on runoff P by estimating annual P losses in mass per unit area.

Selecting performance indicators for farms and ranches engaged in collaborative agroecosystem research

Journal of Environmental Quality, EarlyView.
Abstract The pace of global change complicates the assessment of the outcomes of agricultural management, hindering decision‐making by producers, researchers, and consumers. The Long‐Term Agroecosystem Research Network (LTAR) is in a unique position to advance monitoring to inform decision‐making.
