The very structure of scientific research mitigates against developing products to help the environment,the poor,and the hungry

Conclusions From the arguments I have presented, I hope it is clear that the distinction between basic and applied research is tenuous. Certain areas of research and methods may be favoured over others because of intrinsic biases, which are predictive of the type of application possible. Believing in the neutrality of pure knowledge is like wearing blinders: scientists need not be too concerned about the way in which the knowledge they generate is used. In my own case, this belief led to my participation in a system of agriculture to which I do not subscribe. Scientists should be willing to take responsibility for how they function in the system as a whole. Given the social structure of science, it is difficult for basic researchers to see their connections with the larger issues, much less to control them. Perhaps new ways of constructing knowledge-generating societies will be necessary in order to encourage individual responsibility.     

Mulesing and Animal Ethics

People for the Ethical Treatment of Animals (PETA) called for a ban on mulesing in the Australian sheep industry in 2004. Mulesing is a surgical procedure that removes wool-bearing skin from the tail and breech area of sheep in order to prevent flystrike (cutaneous myiasis). Flystrike occurs when flies lay their eggs in soiled areas of wool on the sheep and can be fatal for the sheep host. PETA claimed that mulesing subjects sheep to unnecessary pain and suffering and took action against the Australian wool industry that resulted in a number of international clothing retailers choosing not to use Australian wool. Although the Australian sheep industry agreed to phase out mulesing in 2010, there is some uncertainty as to whether this deadline will be achieved. The changing social ethic towards animal welfare suggests that the way the Australian sheep industry manages the phase out of mulesing in 2010 is vital to its future survival and success. It is likely that if mulesing does not cease in 2010 there will be a negative market reaction to Australian wool and the risk of legislation to ban mulesing. To avoid losing control of its animal welfare strategy, the Australian sheep industry should ensure that mulesing is phased out in 2010 and endorse the animal welfare ethic underpinning this change. The industry should also educate farmers and other industry stakeholders in how the changing social ethic for animal welfare can create new market opportunities for wool.     

Issues Associated with Research on Sheep Parasite Control in New Zealand – a Descriptive Ethic

In common with much of theEnglish-speaking world, New Zealandersgenerally oppose the use of animalexperimentation where there is no demonstrableand immediate benefit for human, animal, orenvironmental health. Intrusive experiments onsheep internal and external parasites publishedbetween 1996 and 2000 are reviewed, anddiscussed in relation to these publicsensibilities. A total of 16 publishedexperiments on sheep parasites involvedsurgical manipulations or other intrusiveprocedures. Some of these experiments had noshort-term application, or the only applicationwas in increasing animal production. Otherscould have been modified at some extra expenseso that they were less intrusive. Still otherswere duplications of previous work. All thesemanipulations would be unacceptable accordingto the orthodox morality of the general public.Breeding programs, rotation of grazing,``low-tech' vaccination, and in vitromodels of sheep can provide insights intopreventing parasite infestation withoutintrusive experiments. Such research protocolsshould take priority over existing programs.The results also confirm earlier reports thatanimal ethics committees are not fulfillingtheir mandated objective of acting as watchdogsfor the public. Possible changes in New Zealandanimal welfare legislation and itsinterpretation by Animal Ethics Committees arediscussed.     

Strengthening Agricultural Research in Africa

Training programmes that involve agricultural researchers with farmers and extension field-workers have helped national agricultural research systems in sub-Saharan Africa to improve their communication with farmers. The International Institute of Tropical Agriculture (IITA) has worked with national crop research institutes and agricultural extension agencies in building communication links with farmers. In a continent where population growth still outstrips food production increases, feedback from farmers on performance of high-yielding crop varieties and on new farming techniques is essential in boosting food production.     

MANAGING GROUND WATER QUALITY IN RELATION TO AGRICULTURAL ACTiVITIES1

ABSTRACT: Ground water quality is an environmental issue of national concern. Agricultural activities, because they involve large land areas, often are cited as a major contributor of ground water contaminants. It appears that some degree of ground water contamination from agricultural land use is inevitable, especially where precipitation exceeds evapotranspiration. For this reason, and because agriculture differs significantly from point sources of pollution, farmers, policymakers, and scientists need alternative management strategies by which to protect ground water. Mathematical models coupled to geographic information systems to form expert systems can be important management tools for both policymakers and agricultural producers. An expert system can provide farmers, researchers, and environmental managers with information by which to better manage agricultural production systems to minimize ground water contamination. Significant research is necessary to perfect such a system, necessitating interim ground water management strategies that include not only a strong research program, but educational and public policy components as well.     

Is trade liberalisation bad for the environment? A review of the economic evidence

The continued growth in world trade and investment flows has led to a renewed interest among researchers and policy makers in the potential impact that trade liberalisation policy may have on the environment. The aim of this paper is to provide a balanced and accessible summary of the findings of recent economic research on the impact of growth in international trade and investment on environmental quality.     

A project-based system for including farmers in the EU ETS

Farmers in the EU do not trade greenhouse gases under the Kyoto agreement. This is an empirical puzzle because agriculture is a significant contributor of greenhouse gases (GHG) in the EU and may harvest private net gains from trade. Furthermore, the US has strongly advocated land-use practices as 'the missing link' in past climate negotiations. We argue that farmers have relatively low marginal reduction costs and that consequences in terms of the effect on permit price and technology are overall positive in the EU Emission Trading System (ETS). Thus, we propose a project-based system for including the farming practices in the EU ETS that reduces the uncertainty from measuring emission reduction in this sector. The system encourages GHG reduction either by introducing a new and less polluting practice or by reducing the polluting activity. When doing so, farmers will receive GHG permits corresponding to the amount of reduction which can be stored for later use or sold in the EU ETS.     

Farmers’ Perceptions of Land Degradation and Their Investments in Land Management: A Case Study in the Central Rift Valley of Ethiopia

To combat land degradation in the Central Rift Valley (CRV) of Ethiopia, farmers are of crucial importance. If farmers perceive land degradation as a problem, the chance that they invest in land management measures will be enhanced. This study presents farmers’ perceptions of land degradation and their investments in land management, and to what extent the latter are influenced by these perceptions. Water erosion and fertility depletion are taken as main indicators of land degradation, and the results show that farmers perceive an increase in both indicators over the last decade. They are aware of it and consider it as a problem. Nevertheless, farmers’ investments to control water erosion and soil fertility depletion are very limited in the CRV. Results also show that farmers’ awareness of both water erosion and soil fertility decline as a problem is not significantly associated with their investments in land management. Hence, even farmers who perceive land degradation on their fields and are concerned about its increase over the last decade do not significantly invest more in water erosion and soil fertility control measures than farmers who do not perceive these phenomena. Further research is needed to assess which other factors might influence farmers’ investments in land management, especially factors related to socioeconomic characteristics of farm households and plot characteristics which were not addressed by this study.     

Natural zeolites

Zeolites, a suite of porous, fine-grained minerals commonly found in certain near-surface, sedimentary rocks, have special physical and chemical properties that could make them valuable to farmers in developing countries. Zeolites have been used to improve soil fertility; develop slow-release fertilizers; improve animal waste disposal; and improve animal health. To date most research on zeolite deposits and their various applications has been undertaken by the industrialized nations. Some zeolite deposits, however, also exist in developing countries and the likelihood of the existence of additional deposits in those countries is high. However, thorough assessment of the mineralogy, geology, and various agricultural uses is still needed. Strengthening developing countries' geological surveys in non-metallic mineral exploration and assessment will improve the likelihood that the use of zeolites will reach their full potential in developing country agriculture.     

Simultaneous adoption of integrated soil fertility management technologies in the Chinyanja Triangle,Southern Africa

Empirical scientific evidence indicates that there is still room for increasing food production by improving land productivity. This study aimed at identifying the key determinants that govern farmers’ decisions to adopt multiple components of integrated soil fertility management (ISFM) in a maize mixed cropping system of the Chinyanja Triangle, Southern Africa. Revealed preferences of ISFM components were collected from 320 randomly selected households and multivariate probit (MVP) model was used to analyse the simultaneous effects on adoption based on biophysical plot and household‐level socioeconomic attributes. The results show that farmers’ choices of a set of ISFM components are determined by a mix of factors that address the trade‐offs and synergies among them. Non‐farm income, moderate land quality perception, and education influence simultaneous technology adoption, while gender and crop loss increase the likelihood of farmers’ decisions to adopt independent options. Having other sources of income supports co‐adoption of inorganic fertilizer, residue incorporation, and crop rotation. Input/output market access, access to information, financial sources, and climate variability also play pivotal role in technology adoption. These results indicate that resource availability, learning costs, finances, and risk aversion need to be considered when designing and promoting ISFM technologies as a package.     

Ethical Considerations in Agro-biodiversity Research,Collecting, and Use

Humans have always played a crucial role in the evolutionary dynamics of agricultural biodiversity and thus there is a strong relationship between these resources and human cultures. These agricultural resources have long been treated as a global public good, and constitute the livelihoods of millions of predominantly poor people. At the same time, agricultural biodiversity is under serious threat in many parts of the world despite extensive conservation efforts. Ethical considerations regarding the collecting, research, and use of agricultural biodiversity are currently topics of great concern. For example, easy access to genetic resources for breeding purposes is important, but international agreements and legal frameworks are necessary to ensure adequate recognition of the contributions of local communities and traditional farmers in creating and nurturing these resources. Here, we assess ethical principles in the context of existing codes of conduct that are relevant for agro-biodiversity researchers. We aim to create awareness among scientists and policy makers who are concerned with agro-biodiversity research and its potential impact on local communities. We encourage a serious assessment of the ethical principles presented here and hope to facilitate an integration of these principles into the reader’s personal ethical framework. Key ethical principles considered here include the importance of obtaining prior informed consent, equity, and the inalienability of rights of local communities and farmers.     

Joint submissions,output related payments and environmental co-operatives: Can the Dutch experience innovate UK agri-environment policy?

This paper describes three relatively recent innovations in the Dutch agri-environment programme which have helped nature management to be contiguous with natural features allowing the landscape to be managed whole rather than piecemeal—and thus generate higher quality and greater scope in environmental management. The first two, joint submissions by neighbouring farmers and payments related to the level of environmental output delivered, are scheme innovations. The third, Environmental Co-operatives (EC)—clubs of neighbouring farmers that inter alia co-ordinate and help manage the scheme innovations—is an institutional innovation. None has an equivalent in the UK. Evidence from interviews with farmer and non-farmer members, policy makers, academics and other interested parties show the role EC play in overcoming some of the postulated problems of the two scheme innovations. Not all the problems have been overcome, and cost-benefit analyses have not been conducted, nevertheless there is sufficient evidence to suggest that these innovations have benefited all actors involved: farmers, the government, the environment and the rural economy. Analysis of UK agri-environment policy using actor network theory (ANT) suggests the UK government will need to show similar levels of trust in and commitment to the farming community before these innovations could be introduced in the UK.     

Virgil, Vigilance, and Voice: Agrifood Ethics in an Age of Globalization

Some 2000 years ago, Virgil wroteThe Georgics, a political tract on Romanagriculture in the form of a poem. Today, as aresult of rising global trade in food andagricultural products, growing economicconcentration, the merging of food andpharmacy, chronic obesity in the midst ofhunger, and new disease and pest vectors, weare in need of a new Georgics that addressesthe two key issues of our time: vigilance andvoice. On the one hand, vigilance must becentral to a new Georgics. Enforceablestandards for food safety, food quality,environmental protection, worker health andsafety, sanitary and phytosanitaryrequirements, animal welfare, and appellationsmust be addressed. On the other hand, a newGeorgics must increase the range of persons whohave voice in the democratic governance of anew global agrifood system. New organizationsand institutions will be needed to accomplishthis task.     

Drivers and barriers to water transfer in a New Zealand irrigation scheme

Policy makers, economists and water researchers have advocated water transfer and trade as a key potential response to worldwide water scarcity and/or efficiency problems. This paper examines aspects of an operational irrigation scheme in New Zealand that enables transfer of water between shareholders, arguing that the set-up and processes involved with the scheme can provide a wider context for analysis and consideration of social and cultural issues involved with resource allocation. Analysis of the key drivers and barriers for water reveal that while there is potential for real benefits from transferring water for farmers and the community, an examination of some of the processes used, and barriers to transfer reveals important lessons for planning and regulatory perspectives, including the importance of looking at the issues from a procedural and distributive justice viewpoint.     

The livestock revolution, food safety, and small-scale farmers: why they matter to us all

Global consumption, production, and trade of livestock products have increased rapidly in the last two decades and are expected to continue. At the same time, safety concerns regarding human and animal disease associated with livestock products are increasing. Efforts to increase public health safety standards aimed at legitimately reducing the risks of human and animal disease have focused internationally on standards to regulate the movement of livestock products. There is concern, though, that measures to regulate these standards internationally, such as the WTO SPS measures that in part aim to open international markets, may marginalize small-scale poor producers. The cycle of poverty they are trying to escape through livestock production may, in fact, widen, leading to increased global poverty, malnutrition, and disease. Developing and developed nations alike should be concerned with public and private efforts to address appropriate food safety policies to reduce the likelihood of this effect. Analysis of the impact on small-scale livestock farmers is needed, as well as solutions that consider joint public and private sector initiatives. Costly farm to table tracking systems are not an option, but locally orchestrated vertically integrated systems may have merit in reducing food safety risks and in providing small-scale farmers with increased access to markets, locally and internationally. Increased scientific and technical capacity, and training of WTO officials from developing nations is also needed.     

Towards a science of sustainable upland management in developing countries

Farmers attempting to subsist in tropical uplands often rely upon unsustainable resource use practices that lead to soil erosion, declining crop yields, and a loss of soil productivity capacity. Other uses of tropical uplands, including logging and conversion of forest to rangelands, have similar results. The undesirable effects of these actions are felt on-site, at the watershed level, and even nationally. Ecological cause-effect relationships are poorly understood, and few examples exist of the successful integration of ecological knowledge with upland development. It is hypothesized that recent results of ecological research could be applied to uplands management so that stable sustainable systems of human use may be established. A second hypothesis is that statistically reliable data can be obtained from experiments in upland situations, although natural variations of soils, weather, and vegetation are great. To test these hypotheses, research involving multinational collaboration among American and Southeast Asian scientists has begun. The objective of the work is to provide credible quantitative information to help policy and decision makers and resident farmers to plan and implement improved practices based on ecological principles.Some findings to date include:

Are farmers in England equipped to meet the knowledge challenge of sustainable soil management? An analysis of farmer and advisor views

Concern about the agricultural soil resource in England has led to the introduction of a range of measures, which potentially challenge farmers' knowledge about the soil and its management. Our understanding however of how well-equipped farmers are with regard to effectively carrying out more complex and knowledge intensive sustainable soil management practices is limited. Specifically, by drawing on the concept of scientific and tacit forms of knowledge, this paper examines the knowledge of soils held by farmers through analysis of data collected from semi-structured interviews with farmers and agricultural advisors and supplemented with data from an extensive postal questionnaire survey of advisors. The data indicate that, while farmers are technically well informed, they can often lack the in-depth scientific knowledge required to implement more complex practices such as using the nutrient value of manures. They also reveal that, while most farmers have good knowledge of their own soils, their tacit knowledge of soil management can be weak, notably in relation to cultivation. The paper concludes that although farmers' knowledge about soil and its sustainable management appears in general to be well developed there are some areas, which need to be significantly enhanced and as such require both a policy response and further research effort.     

Managing fodder trees as a solution to human–livestock food conflicts and their contribution to income generation for smallholder farmers in southern Africa

Livestock production is an integral part of smallholder farming systems in southern Africa. While goats and sheep play some role in the smallholder farmer household economy, cattle are the predominant livestock species supplying draught power, milk, manure and meat. Production of cattle is based on range grazing. However, the nutritive value of the range is generally low depending on vegetation type and season. With the rapid increase in human population in southern Africa and the increasing need to produce staple food on a sustainable basis, smallholder farmers are increasingly encroaching onto lands formerly reserved for livestock grazing. Therefore, livestock subsisting on the range require supplementation. Conventional bought‐in supplements are expensive. Fodder trees and shrubs have been integrated within some farming systems of southern Africa as fodder banks with varying degrees of success. Work carried out in Tanzania, Malawi and Zimbabwe is reviewed to provide evidence on how the fodder tree technology has impacted on livestock production with special reference to smallholder dairy production, human food production and smallholder farmers’ income. For the wider adoption of the technology, a synopsis of the different scaling up pathways and approaches adopted by research and development agencies is presented.     

Sustainable rural development in Sokoto State, Nigeria

In Nigeria, as in most countries, institutional barriers to successful rural development exist and need to be addressed. In Sokoto State, a variable and unpredictable Sahelian climate in combination with conditions of high population growth, low levels of income, and environmental degradation, create and intensify institutional challenges. This study examines the sustainability of government initiatives regarding the provision of agricultural inputs, assistance and extension services to farmers, and the extent to which agency efforts are coordinated and integrated, particularly regarding water management. In some cases, rural development agencies demonstrated the capability to meet the needs of the people. Some farmers were satisfied with government assistance and in some areas the tube well programme was quite successful. Yet in Sokoto State many institutional barriers to sustainable rural development exist and need to be addressed. In general, implementation strategies and management procedures appeared narrowly focused and placed little emphasis on coordination and integration among rural development agencies. The result was often inappropriate overlap or oversights in activities .     

Trialling a web-based spatial information management tool with Land Managers in Victoria,Australia

A prototype web-based spatial information management tool (called eFarmer) was tested for its useability and usefulness by 46 Land Managers and 5 extension staff in Victoria, Australia. Participants had a range of enterprises (dairy, beef/sheep grazing, cropping, lifestyle land use), property sizes and computer ownership and expertise. A follow up study was conducted with 12 dairy farmers, where features regarding assessment of nutrient losses from paddocks (Farm Nutrient Loss Index, FNLI) were added to eFarmer. Over 27,000 maps (including 11,000 with aerial photography) were accessed by Land Managers during a 5-month trial period. Despite limited training and support, 1350 people are registered users, and approximately 700 have actively used the tool. Reasons for the success include providing improved access to spatial information, enabling measurement of farm features and creation of farm maps, providing a basis for decision-making about farm inputs, support for better farm and landscape scale action planning and production and Land Managers being able to seek management advice from the extension staff who facilitated eFarmer testing programs. For dairy farmers in the FNLI trial, awareness of off-site impacts increased and most changed management practices. Provision of on-going training and support will be at least as important as further development of the tool itself. Web-based spatial information tools have potential to improve the awareness of Land Managers about their environmental impacts and influence their decision-making. Access to spatial information has potential to reduce information asymmetry between Land Managers, extension staff and catchment planners in a constructive way. It will also change the role of extension staff away from being an expert with answers, to a facilitator enabling learning. Results have applicability in countries where there is a high level of farm computer ownership, relevant spatial information is available in GIS format, where governments are happy to make spatial information available to the public and there is pressure for increased environmental awareness and improved decision making by Land Managers.
