ABSTRACT

Agricultural nutrients in the wrong places pose threats to water quality in the United States,  but  the  federal  government  has  little  control  over  the  issue.    States  do  have authority over nonpoint sources such as agricultural nutrient runoff, but what are they doing to address water quality threats?  This paper presents an overview of different approaches  states  are  utilizing  to  reduce  agricultural  nutrient  impacts  on  water.  Approaches fall into seven categories that range from statewide reduction strategies to nutrient  application  restrictions  and  external  partnerships.    Voluntary  incentives remain  a  priority,  but  a  slight  trend  toward  mandatory  requirements  exists.    The current  landscape  is  well-populated  with  a  diversity  of  state  actions,  but  funding, impact monitoring and coordination may prove critical to program and policy success.

ABSTRACT

A belief that the current natural resource management (NRM) delivery model in Australia is failing to provide tangible on ground outcomes within the farming sector is proving to be a catalyst for the examination of alternative delivery models. However, there exist workable examples contributing to on-farm NRM and production outcomes that provide value for money investment, with the flexibility to cater to local needs at a sub-regional level. These community-based models owe their success by being truly community driven and more closely linked to producers and local government than the regional NRMs are. The Tamar Valley has such a community driven model, which demonstrates another way for NRM program and project delivery into the farming sector.

ABSTRACT

In this paper we present a novel application of the difference-in-difference method to analyse the effect of regulation on agricultural land prices in the case of implementation of mandatory riparian buffer zones. The buffer zones are adjacent to streams and lakes and are designated as part of the Danish implantation of the EU Water Framework Directive. The buffer zone regulation existed from 2012 to 2015 when the regulation was suspended. Using a hedonic price model we do a difference-and-difference estimation of the development in regional farm land prices for farms with land subject to the buffer zone regulation compared to farms not subject to buffer zones. A number of model specifications are tested but no significant effect on land prices of the buffer zone regulation is identified. This is explained by the fact, that the regulation was based on a subsidy scheme offering flat rate compensation to farmers obliged to establish buffer zones. Thus, results suggest that due to the subsidies, farmers’ expectations for the future economic rent are unchanged and, thus, no significant effects on the land prices are identified.

ABSTRACT

The paper presents preliminary results form a real-life project in which five economic services are pursued through multifunctional land consolidation processes: Farm economics; Biodiversity; Clean water; Recreational opportunities; and Development of rural communities. The analysis is based on the first results from three Danish case studies where land consolidation is used to facilitate multifunctional land consolidation. We find that the multifunctional goals are generally aligned with agricultural economics goals and the optimal consolidation of land plots are not fundamentally differing between economic services with different goals. The fundamental benefit from this approach is local ownership to process and results due to the collective policy formulation. One more specific lesson learned is though, that access to recreational activities such as hunting and horseback riding, which is tied to the ownership of land, may indeed represent significant value to the landowner and this can highly influence the scale and scope of the consolidation.

ABSTRACT

Ohio residents have been calling for changes in agricultural practices since harmful algal blooms have disrupted recreational use of lakes and drinking water supplies in the Western Lake Erie Basin. These blooms are a result of phosphorus (P) loading into waterways from a number of sources, including agriculture fertilizer and manure use on fields. P loss only accounts for about 0.49 lb/A but equates to roughly 2 million pounds of P each year being dumped into the Basin. Regulations have been put in place to educate farmers on nutrient management and reduce nutrient losses. Three tools have been updated and developed to help farmers reduce P losses: 1.) Updated Tri-State Fertilizer Recommendations, 2.) Updated Ohio Phosphorus Risk Index tool, 3.) Field Application Resource Monitor. These tools address the source, rate and timing of nutrient applications. The cost of implementing these practices varies from farm to farm. Some farms may see no change to their budgets where other farms may see an increase in expenses.

ABSTRACT

Energy consumption is an important component in determining the sustainability of farming practices. Identification of dairy farming systems with efficient energy consumption at the same time as minimising greenhouse gas emissions is vital. In this context, it is relevant to assess the energy footprint of different dairy farming systems in order to identify a sustainable dairy system for the future of NZ dairy industry.

This research is based on comparative analysis of Pastoral (PDFs) and Barn (BDFs) dairy farming systems in Canterbury, New Zealand. A total of 50 dairy farms were investigated, using direct (fuel, electricity, labour) and indirect (fertilizer, feed supplements, machinery and equipment) energy inputs.

The results indicate that PDFs system have 9.5 percent lower energy footprint per hectare than BDFs, mainly due to their greater reliance on pasture based grazing feeding and less use of electricity, fuel and feed supplements. Of interest is that the BDFs use 39% less fertiliser energy but 80% higher feed supplement energy based on the inputs the farmers used. In terms of per kilogram milk solids produced, the PDFs shows 6 % lesser energy footprints compared to BDFs. This research suggests that energy consumption in PDFs in terms of both hectare and milk output is more efficient. However, when considering individual inputs of each system, the energy usage for fertilizer is much higher in PDFs.

Hafiz Muhammad Abrar Ilyas, an agricultural engineer and PhD research scholar at Lincoln University, New Zealand. My research interests are in dairy farming, especially in farm management systems and practices that lead to sustainability and environmental betterment. My PhD research focuses on evaluation of NZ Pastoral (PDFs) and Barn (BDFs) dairy farming systems in terms of energy footprint and greenhouse gas emissions. This research work has allowed me to dig deeply into different dairy farming systems of New Zealand to understand their energy consumption and efficiencies. The findings of this research will help in making environmental policies regarding NZ dairy farming systems and will also guide farmers to move towards sustainable farm practices. I am looking forward to working alongside farmers to help them optimize their farming systems and meeting environmental targets, while continuing to broaden my knowledge within the primary industries. I enjoy being part of the agricultural groups and has always loved the outdoors and spending time on farms.

ABSTRACT

Given the significance of maize within the overall food security strategies in Sub- Saharan Africa including South Africa, it is important to analyse the technical efficiency of the maize industry for the overall development of the economy.  This article analyzes the impact of labor productivity, import price of the world, research and development on technical efficiency of maize industry in South Africa using a Computable General Equilibrium model and South Africa Social Accounting Matrix. The result revealed that maize producers used less intermediate inputs, value-added drops, increased export and reduced import due to an increase in production. Despite the rise in maize output, the demand for labour reduced. This was due to the indirect effect than a direct effect of the maize sector technical efficiency improvements. The study recommends that the improvement of technical efficiency directly related to competitiveness and welfare, therefore, in spite of employment reducing effect, the

ABSTRACT

There are considerable challenges to be faced to earn a livelihood from the semi-arid land of Laikipia, Kenya. These include periodic droughts, lack of water resources, poor infrastructure, lack of political support and the need for cooperation with neighbours. Since Kenya became independent in 1963, there have been big changes in the management of these properties, the most notable being the introduction of tourism in the 1980s which has prospered owing to the large reservoir of wildlife which exists in the area and the formation of Conservancies to protect the latter. Much of the income of the ranches is now derived from upmarket tourist lodges and safaris. However, they are still major food producers especially of quality livestock and some crops. Particular reference is made to the combined Lewa/Borana Conservancy which consists of two privately owned conservancies which have removed the fences between them to establish the largest Conservancy in the Country with a rich population of wildlife. A large area of land within Lewa was owned by one of the author’s relatives until the 1980s and his personal experience of its development over the past half century is detailed in this presentation. Conclusions for a better future are drawn.

 ABSTRACT

Since 1995 populations of wallabies, predominantly Bennetts wallaby (Macropus rufogriseus), and to a lesser degree Tasmanian pademelon (Thylogale billardierii), have been abundant in King Island landscapes, impacting natural and agricultural environments. King Island lies between Tasmania and mainland Australia, encompassing 110 000 ha of predominantly flat landscapes, some plateau country, and a large extent of cleared pasture land with remnant bushland. The island boasts quality beef and dairy production, and pristine natural environments. To manage wallabies, and their browsing impacts on natural and agricultural environments in 2013 a Wallaby Management Coordinator was employed by the Tasmanian Government’s Department of Primary Industries, Parks, Water and Environment. Management encompasses wallaby-proof fencing, shooting, education and neighbour co-operation. Seven properties initially engaged in wallaby management. Today thirty-one properties engage in wallaby management, and eighty have Crop Protection Permits. In six years an average of 71 667 wallabies have been culled per year, and 240 kilometres of wallaby-proof fencing has been installed. Properties engaged in wallaby management are reaping the rewards, with one property reporting a 75% increase in production in three years of wallaby management. The future profitability of agricultural production relies on continual management of these species.

IS SHEEP DAIRYING A MORE SUSTAINABLE LAND-USE PARADIGM FOR NEW ZEALAND THAN COW DAIRYING?

Sue Trafford1, Guy Trafford1

ABSTRACT

New Zealand’s economy is dependent on cow dairying’s contribution of approx. $7.8 billion to total GDP. However, it faces ratcheting  pressure for more regulatory controls as the result of intense public scrutiny of its environmental footprint, predominantly relating to water supply and quality. Sheep dairying is being heralded as a potentially profitable export industry with a significantly lighter footprint while capitalising on the longstanding skills and infrastructural base of a historic, national sheep farming industry. Yet, there is limited definitive information available as to whether sheep dairying can/ does deliver its promise with regard to environmental and other benefits. This paper explores a range of literature/data that outlines the benefits of sheep comparative to cow dairying in the New Zealand context and compares findings to those of an ongoing, commercial research project (Charing Cross Sheep Dairy) established in 2011 in the Canterbury region. It also explores benefits to communities, and animal welfare.
