Sustainability: meaning and measurement with application to agriculture

Sustainability refers to having the ability to meet present needs without impacting on future generations to meet their needs. It incorporates social, economic and environmental aspects, and as a measure of sustainability, a range of sustainability indicators at the economy, regional, and individual level, have been suggested. However, given the complex and multidisciplinary nature of the concept, an interdisciplinary approach is necessary. Sustainability is not something that is easily measurable, and the aim of this paper is to present a conceptual framework for quantifying sustainability on the basis of social economic efficiency. According to neoclassical economic theory, economic activity will only be sustained by the private sector as long as it is profitable. However, private economic decisions do not always ensure long-term sustainability of environmental resources or production. The approach suggested here is to derive a measure of social economic efficiency as a measure of sustainability. For dairy farmers, increased productivity has been emphasized, while recognizing the need to reduce greenhouse emissions, pests and disease, nutrient run-off into the environment and degradation of the soil structure. By incorporating environmental and economic impacts, a fuller measure of efficiency, social economic efficiency, and sustainability of the farming practice can be developed.

Opportunities for reclaimed water use in Australian agriculture

This paper provides an overview of how Australia exploits its water resources with a focus on reclaimed water. Arguments are brought up for the high value horticultural sector (vegetables, fruits and grapes) being a competitive customer for reclaimed water. Factors to consider when assessing the suitability for reclaimed water use in horticulture either for substitution of existing water resources or expansion of production are discussed.

Effective farmer groups for defining best practices for sustainable agriculture

Practitioners and farmers are practical people. They are likely to be more comfortable with a process that develops monitoring tools and benchmarks for natural resource management than a process of group development and social capital formation. Yet the two are intrinsically linked. Policy makers and extension workers need to understand the link, and how to use a knowledge of social processes when designing the more concrete process of developing and implementing best practice monitoring and benchmarking with groups.

This paper reflects on the experience of establishing and working with farmer groups as they go through a process of identifying environmental issues, setting and monitoring environmental benchmarks and identifying and implementing sustainable farming practices to meet the benchmarks.

Learning in agriculture : building social capital in island communities

Social capital helps communities respond positively to change. Research in agricultural businesses and into managing change through learning in communities has highlighted the importance of relationships between people and the formal and informal infrastructure of communities to the quality of outcomes experienced by communities, businesses and individuals. Communities can be geographic communities - the data drawn on in this paper are from an island community, for example or communities-of-common-purpose, such as agricultural organisations. This paper reviews research into managing change through learning and social capital, presents a model of the simultaneous building and use of social capital and explores the ways in which learning as part of an agricultural community can be used to bring benefits to geographic communities such as islands. The model presented in this paper stems from studies of the informal learning process that builds resilient communities. It conceptualises the way in which social capital is used and built in interactions between individuals. There are two stages to the model. The first stage depicts social capital at the micro level of one-on-one interactions where it is built and used. The second stage of the model is about the interrelationship of micro-level social capital processes with the community and societal-level social capital resources.

Reforms in the Bangladesh agriculture input sector : room for complacency?

Market-based reforms implemented in the agricultural input management system are often claimed to be one of the success stories in Bangladesh. Based on the findings of 154 surveys and 16 in-depth interviews with the stakeholders during 2003-2004, the paper found that although there have been some notable achievements, the reforms have not achieved their expected outcomes and more importantly, in cases where they have been achieved, their sustainability is in question. The paper discusses the underlying reasons for the success and the problems of the reforms and also offers some policy recommendations to resolve the gap between the expected and the achieved outcomes. In the context of increasing donor pressure for adopting market-based reforms, the findings are likely to have important implications for both the donors and other countries in South Asia.

Working with farmers for better agriculture in Timor Leste

Agricultural production in Tirnor Leste is of vital importance, both for the majority of the population who rely primarily on agricultural production for their livelihoods, but also in the broader development agenda of this new nation. The post independence lack of public agricultural extension and the destruction of much the resource base led to the current situation whereby the NGO sector is the primary provider of advice, extension and access to resources for agricultural production. The very recent move to invest once more in public agricultural extension services provides a timely point to assess the role, approach, issues and opportunities faced by NGOs. This research is based on discussions with a number of NGO personnel, both local, national and international and raises a number of questions regarding how the wide variety of organisations engage with communities, their objectives, inputs, coverage, and impacts. The discussion is framed by an analysis of the changing practices in agricultural extension and the associated role of NGOs, and questions how best the agricultural sector rnight move forward in providing appropriate support to the farmers of Timor Leste..

Origins of agriculture at Kuk Swamp in the highlands of New Guinea

Multidisciplinary investigations at Kuk Swamp in the Highlands of Papua New Guinea show that agriculture arose independently in New Guinea by at least 6950 to 6440 calibrated years before the present (cal yr B.P.). Plant exploitation and some cultivation occurred on the wetland margin at 10,220 to 9910 cal yr B.P. (phase 1), mounding cultivation began by 6950 to 6440 cal yr B.P. (phase 2), and ditched cultivation began by 4350 to 3980 cal yr B.P. (phase 3). Clearance of lower montane rainforests began in the early Holocene, with modification to grassland at 6950 to 6440 cal yr B.P. Taro (Colocasia esculenta) was utilized in the early Holocene, and bananas (Musa spp.) were intensively cultivated by at least 6950 to 6440 cal yr B.P.

Sui Generis protection for plant varieties and traditional knowledge in biodiversity and agriculture : the international framework and national approaches in the Philippines and India

The so-called ‘biotechnology clause’ of Article 27.3(b) of the WTO-TRIPS Agreement requires from member states protection for plant varieties either via the patent system or via an ‘effective sui generis system’ or by a combination of the two. Many developing countries prefer forms of sui generis protection, which allow them to include exceptions and protection measures for traditional agricultural practices and the traditional knowledge of farmers and local communities. However, ‘traditional knowledge’ remains a vaguely defined term. Its extension to biodiversity has brought a diffusion of the previously clearer link between protected subject matter, intellectual property and potential beneficiaries. The Philippine legislation attempts a ‘bottom-up’ approach focusing on the holistic perceptions of indigenous communities, whereas national economic interests thus far receive priority in India’s more centralist approach. Administrative decentralisation, recognition of customary rights, disclosure requirements, registers of landraces and geographical indications are discussed as additional measures, but their implementation is equally challenging. The article concludes that many of the concepts remain contested and that governments have to balance the new commercial incentives with the biodiversity considerations that led to their introduction, so that the system can be made sufficiently attractive for both knowledge holders and potential users of the knowledge.

Integrating agriculture and food policy to achieve sustainable peri-urban fruit and vegetable production in Victoria, Australia

Efforts to increase fruit and vegetable consump­tion are a significant aspect of national approaches to preventive health. However, policy frameworks for increasing fruit and vegetable consumption rarely take an integrated food-systems approach that includes a focus on production. In this policy analysis and commentary we examine fruit and vegetable production in peri-urban areas of Melbourne in Victoria, Australia, and highlight the significance of emerging environmental and eco­nomic pressures on fruit and vegetable production. This examination will be of interest to other locations around the world also experiencing pressure on their peri-urban agriculture. These pressures suggest that the availability and afforda­bility of fruit and vegetable supplies cannot be taken for granted, and that future initiatives to increase fruit and vegetable consumption should include a focus on sustainable production. Threats to production that include environmental pressures, together with the loss and cost of peri-urban agri­cultural land and a cost-price squeeze due to rising input costs and low farm-gate prices, act in combi­nation to threaten the viability of the Victorian fruit and vegetable industries. We pro­pose that policy initiatives to increase fruit and vegetable consumption should include measures to address the pressures facing production, and that the most effective policy responses are likely to be integrated approaches that aim to increase fruit and vegetable availability and affordability through innovative solutions to problems of production and distribu­tion. Some brief examples of potential integrated policy solutions are identified to illu­strate the possibilities and stimulate discussion.

Biotechnology in U.S. agriculture: Trade consequences for dairy products

The emergence of synthetic bovine Somatotropin (bST) is one of the most widely discussed advances in biotechnology. Its potential impacts on milk production around the world could be significant. However, the exact economic impacts of bST in any one region depends on a number of factors, some of which are still highly controversial.

This article sets out to estimate the economic impacts of the adoption of bST in the United States, the single largest milk producer in the Western world. A quarterly econometric model of the U.S. dairy sector is used to forecast the total production, consumption, and excess supply of milk to 1995. The preliminary results indicate that under the assumption of a gradual rate of adoption and a 15 percent milk production response, the United States could be exporting as much milk as New Zealand by 1995. Should the production response rate or the adoption rate be higher, the United States could indeed become a major competitor in the world dairy market by 1995.

Although such a development could adversely impact on other dairy exporters, such as New Zealand, the precise economic impacts on world prices and trade would depend crucially on the position that other major dairy producers, especially the EC, adopt with respect to the use of bST.
