Using bio-manipulation to optimise nutrient management within intensive farm systems
… such as livestock slurry, on commercial farms represents one route through which the reliance of agricultural production on inorganic fertiliser use might be reduced. For economic, environmental and geopolitical reasons, decoupling future agricultural production from inorganic fertiliser …

Modelling New Zealand dairy farm systems to design greenhouse gas mitigation strategies
… for reducing GHG loads between 10–30% within systems of different production intensity in the main dairy farming regions of New Zealand: Waikato and Canterbury. Pastoral dairy farms, as found in New Zealand, are complex farming systems with many interdependent management variables and any …

Modeling Whole Farm Systems to Enhance Beginning Small Farmer Success in Southwest Virginia
The number of very small farms (<10 acres) is increasing and beginning farmers (in practice for <10 years) are more likely to run them. Very small farms are typically complex systems in which the farmer manages both production of a diverse array of crops and marketing of crops directly to consumers …

Environment, Economics, and Family Farm Systems: Farm Expansion and Adaptation on the Western Slopes of Andean Ecuador (Cultural Ecology)
This study assesses the popularity of multizonal farming on the western slopes of Andean Ecuador. It is based on 18 months of fieldwork in a multiethnic area of Bolivar Province known as Llullundongo, where the sale and expropriation of estates in the first part of this century allowed for farm …

Grazing management strategies of diverse pastures on irrigated dairy farm systems : A thesis submitted in partial fulfilment of the requirements for the Degree of Doctor of Philosophy at Lincoln University
… environmental impacts are sought for dairy farming systems. Two strategies to improve DM production and quality are grazing management and the choice of forage species mixture. While grazing management rules are well developed, particularly timing and intensity, for perennial ryegrass-white …

A farm-level model to evaluate the impacts of current energy policy options
This thesis attempts to show the value of farm-level studies as useful additions to aggregated, national or regional models that are used to analyse the effects of policy on an agricultural economy. A literature survey (Chapter 2) illustrates many applications of the aggregated approach to the …

Climate change impacts and adaptation: a New Zealand dairy system : A thesis submitted in partial fulfilment of the requirements for the Degree of Master Master of Agricultural Science at Lincoln University
Pasture-based farming systems, as in New Zealand, are susceptible to changes in the climate through feed supply variability. Future climate change will likely alter pasture growth patterns, posing opportunities and risks that farmers will have to respond to and adapt to remain profitable. Due to …

Energy harvesting of random wide-band vibrations with applications to an electro-magnetic rotational energy harvester
… energy. Many mechanical or electro-mechanical systems produce mechanical vibrations. The kinetic energy associated with these mechanical vibrations represents a potential source of energy for sensors and other electronics. In fact, as the energy requirements for electronics and wireless …

The economic and financial feasibility of food innovation centers
… and sale. These uses include indoor vertical farms, commercial shared-use kitchens for start-up food businesses, rooftop greenhouses, food halls with local, artisanal vendors, and food-related R&D space, among others. While literature exists on the demand for locally produced food, there is …

A Process-Based Nutrient Model for the Bedded Manure Pack of Confined Beef Systems
… A model was developed based on the Integrated Farm Systems Model (IFSM). The main process for water movement was considered evaporation. Ammonia emissions were simulated based on the urea degradation process in the urine, while nitrous oxide emissions were predicted as denitrification losses. …

Human-environment interactions in rural and agricultural communities: identifying opportunities for sustainability efforts using quantitative, qualitative, and GIS methods
… context in which members of agriculture and food systems must adapt to a changing climate to increase food production while simultaneously rethinking traditional approaches to agriculture to mitigate contributions to climate change. This makes the study of agricultural sustainability, and the …

The feasibility of a commercial-scale recirculating aquaculture system integrating sea urchins (Tripneustes gratilla) and seaweed (Ulva)
… The primary aim of this thesis is to create a farm-scale model to provide clear evidence of the biotechnical feasibility of a T. gratilla-Ulva IMTA system. To develop this model, literature gaps needed to be filled. These gaps became the auxiliary initial objectives, specifically; to determine …
