Effect of nutrient management planning on crop yield, nitrate leaching and sediment loading in Thomas Brook watershed.

Government priorities on provincial Nutrient Management Planning (NMP) programs include improving the program effectiveness for environmental quality protection, and promoting more widespread adoption. Understanding the effect of NMP on both crop yield and key water-quality parameters in agricultural watersheds requires a comprehensive evaluation that takes into consideration important NMP attributes and location-specific farming conditions. This study applied the Soil and Water Assessment Tool (SWAT) to investigate the effects of crop and rotation sequence, tillage type, and nutrient N application rate on crop yield and the associated groundwater [Formula: see text] leaching and sediment loss.

Modeling sediment and nitrogen export from a rural watershed in eastern Canada using the soil and water assessment tool.

Watershed simulation models can be used to assess agricultural nonpoint-source pollution and for environmental planning and improvement projects. However, before application of any process-based watershed model, the model performance and reliability must be tested with measured data. The Soil and Water Assessment Tool version 2005 (SWAT2005) was used to model sediment and nitrogen loads from the Thomas Brook Watershed, which drains a 7.

What motivates farmers to participate in the Nova Scotia environmental farm plan program? Evidence and environmental policy implications.

Program stakeholders are interested in better understanding farmers' experience, and factors that affect farmer participation in the relatively new Environmental Farm Plan (EFP) program, implemented in several provinces in Canada. To increase relevance of the research findings to EFP program administrators and policy makers, the research methods emphasised determining whether relationships exist among program-related variables, and how such relationships affect farmers' decision choices and behaviour. Traditional farmer and farm attributes that have contrasting effects in agricultural innovation adoption and conservation management (namely age, and formal education completed), were not associated with EFP program participation.

From mandatory to voluntary testing: balancing human rights, religious and cultural values, and HIV/AIDS prevention in Ghana.

This paper examines efforts by some churches in Ghana to reduce the spread of HIV/AIDS. The analysis is based on focus group discussions with two groups of men and two groups of women, along with in-depth interviews with 13 pastors and marriage counsellors in the churches studied. In response to government and public criticisms about human rights violations, churches that previously imposed mandatory HIV testing on members planning to marry now have voluntary testing programmes.
