Farmers’ attitudes about farming and the environment: A survey of conventional and organic farmers

Farmers have been characterized as people whose ties to the land have given them a deep awareness of natural cycles, appreciation for natural beauty and sense of responsibility as stewards. At the same time, their relationship to the land has been characterized as more utilitarian than that of others who are less directly dependent on its bounty. This paper explores this tension by comparing the attitudes and beliefs of a group of conventional farmers to those of a group of organic farmers. It was found that while both groups reject the idea that a farmer’s role is to conquer nature, organic farmers were significantly more supportive of the notion that humans should live in harmony with nature. Organic farmers also reported a greater awareness of and appreciation for nature in their relationship with the land. Both groups view independence as a main benefit of farming and a lack of financial reward as its main drawback. Overall, conventional farmers report more stress in their lives although they also view themselves in a caretaker role for the land more than do the organic farmers. In contrast, organic farmers report more satisfaction with their lives, a greater concern for living ethically, and a stronger perception of community. Finally, both groups are willing to have their rights limited (organic farmers somewhat more so) but they do not trust the government to do so.     

Nitrogen turnover on organic and conventional mixed farms

Separate focus on crop fertilization or feeding practices inadequately describes nitrogen (N) loss from mixed dairy farms because of (1) interaction between animal and crop production and between the production system and the manager, and (2) uncertainties of herd N production and crop N utilization. Therefore a systems approach was used to study N turnover and N efficiency on 16 conventional and 14 organic private Danish farms with mixed animal (dairy) and crop production. There were significant differences in N surplus at the farm level (242 kg. N/ha. vs. 124 kg. N/ha. on conventional and organic dairy farms respectively) with a correlation between stocking rate and N surplus. N efficiency was calculated as the output of N in animal products divided by the net N import in fodder, manure and fertilizer. N turnover in herd and individual crops calculated on selected farms showed differences in organic and conventional crop N utilization. This is explained via a discussion of the rationality behind the current way of planning the optimum fertilizer application in conventional agriculture. The concept of marginal N efficiency is insufficient for correcting problems of N loss from dairy farms. Substantial reductions in N loss from conventional mixed dairy farms is probably unlikely without lower production intensity. The concept of mean farm unit N efficiency might be a way to describe the relation between production and N loss to facilitate regulation. This concept is linked to differing goals of agricultural development—i.e. intensification and separation vs. extensification and integration. It is discussed how studies in private farms—using organic farms as selected critical cases—can demonstrate possibilities for balancing production and environmental concern.

Governing sustainability: examining audits and compliance in a third-party-certified organic shrimp farming project in rural Indonesia

Drawing on a case study of an organic shrimp project in Indonesia, this paper provides a preliminary assessment of the use of third-party certification (TPC) to make shrimp aquaculture more environmentally sustainable in a rural setting in Indonesia. Specifically, I examine three processes of TPC: (1) the development of standards, (2) the communication of standards, and (3) the enforcement of standards. My research indicates that TPC is based on technoscientific norms and values and Western ideas of rationality. Thus, implementing TPC in rural settings in the global South may pose additional difficulties, resulting from cultural and structural differences. Consequently, TPC may not be able to be successfully implemented everywhere in the world, especially in the rural South, in its current form.

Influence of alternative and conventional farming practices on subsurface drainage and water quality

Agricultural runoff contributes nutrients to nonpoint-source pollution of surface waters. This study was conducted to investigate the potential use of alternative farming practices to improve water quality. The study examined the effects of both alternative and conventional farming practices on subsurface drainage and nitrogen and phosphorus loss through subsurface drainage from glacial till soils (i.e., Calciaquolls, Endoaquolls, Eutrudepts, Hapludolls) in southwest Minnesota. Alternative farming practices included organic management practices, species biodiversity, and/or practices that include reduced inputs of synthetic fertilizer and pesticides. Conventional farming practices include corn-soybean (Zea mays L.-Glycine max L., respectively) rotations and their associated recommended fertilizer rates as well as pesticide usage. Precipitation was highly variable during the 3-yr study period including a below-average year (2003), an average year (2002), and an above-average year (2004). Results indicate that alternative farming practices reduced subsurface drainage discharge by 41% compared with conventional practices. Flow-weighted mean nitrate-nitrogen (nitrate N) concentrations during tile flow were 8.2 and 17.2 mg L(-1) under alternative and conventional farming practices, respectively. Alternative farming practices reduced nitrate N losses by between 59 and 62% in 2002 and 2004 compared with conventional practices. Ammonium-nitrogen (ammonium N), orthophosphorus, and total phosphorus losses in subsurface drainage were very low and did not pose a substantial risk of pollution. Results suggest that alternative farming practices have the potential to reduce agricultural impacts on water quality.     

Vulnerability of the South African farming sector to climate change and variability: An indicator approach

This paper analyses the vulnerability of South African agriculture to climate change and variability by developing a vulnerability index and comparing vulnerability indicators across the nine provinces of the country. Nineteen environmental and socio‐economic indicators are identified to reflect the three components of vulnerability: exposure, sensitivity, and adaptive capacity. The results of the study show that the regions most exposed to climate change and variability do not always overlap with those experiencing high sensitivity or low adaptive capacity. Furthermore, vulnerability to climate change and variability is intrinsically linked with social and economic development. The Western Cape and Gauteng provinces, which have high levels of infrastructure development, high literacy rates, and low shares of agriculture in total GDP, are relatively low on the vulnerability index. In contrast, the highly vulnerable regions of Limpopo, Kwazulu‐Natal and the Eastern Cape are characterised by densely populated rural areas, large numbers of small‐scale farmers, high dependency on rain‐fed agriculture and high land degradation. These large differences in the extent of vulnerability among provinces suggest that policymakers should develop region‐specific policies and address climate change at the local level.     

Potential energy production from organic waste and its environmental and economic impacts at a tertiary institution in Palestine

Municipal solid waste (MSW) is one of the most well-known biomass resources that can be utilized to produce renewable energy. Numerous countries are plagued by the proliferation of waste, particularly organic waste that can be utilized for energy recovery. Palestine suffers from inefficient solid waste management, and only recently have a few projects focused on bioenergy production been implemented. Throughout the years, the city of Tulkarm experiences power outages which cause a challenge to the Palestine Technical University-Kadoorie campus in Tulkarm. Thus, the possibility of energy recovery from the organic portion in Palestine Technical University-Kadoorie was evaluated. The analysis of an economic impact included discussions of a number of economic aspects, including Levelized cost of energy, internal rate of return, present worth, annual worth, and payback period. On the other hand, a carbon dioxide savings analysis and gas emission were evaluated. The outcomes of the energy optimization demonstrated that the suggested system could supply the institution with an average of roughly 7 MWh of electrical energy. According to the economic study, this project offers 0.25 million dollars in present value, 0.144 million dollars in annual value, a 13 percent internal rate of return, a payback period of 6 years, and a levelized cost of energy of 0.11 dollars for each kWh generated. Additionally, the environmental assessment revealed that this system might reduce CO₂ emissions by around 8,343,778 tons. For effective waste management, energy recovery, and emission reduction, it is advised to implement anaerobic digestion technology.     

Economics of an ecotourism operation in Belize

The economic inputs and outputs for the Possum Point Biological Station in Belize during 1990–1992 are described to illustrate some aspects of an ecotourism operation. Eight hundred fifty-four people in 59 groups visited Possum Point during the study period to tour rain forests, estuaries, and coral reefs. The economic input to Possum Point from these groups increased from $74,552 in 1990 to $166,268 in 1992. Outputs were for license fees, capital improvements, goods and services, labor, fossil fuels, and development of a historic sugar mill site. An annual donation was also made to a scholarship fund for local Belizean students. The net cash balance of income and outputs changed from negative (−$6678) in 1990 to positive (+$4811) in 1992, suggesting development of the economic operation. Possum Point meets the economic criteria for ecotourism by feeding back some tourist monies for community and environmental support, particularly donations for the sugar mill site and the scholarship fund. Most of the outputs from Possum Point (about 80%) were retained in the local economy through employment and purchases, which have a positive influence on the local community. We conclude that ecotourism operations, such as Possum Point, offer important sustainable development opportunities for Belize.

Fourier transform infrared and fluorescence spectral features of organic matter in conventional and organic dairy manure

Organic dairy production has exhibited potential for growth in the United States dairy sector. However, little information is available on whether there is any difference in manure composition and quality between organic (OD) and conventional (CD) dairy manure even though the composition and quality are important parameters with respect to availability, utilization, and cycling of manure nutrients and environmental impact evaluation. We comparatively characterized whole and water-extracted materials of 15 OD and seven CD dairy manure samples by Fourier transform infrared (FT-IR) and fluorescence spectroscopies. Fourier transform infrared features of manure organic matter varied mainly in the 1650 to 1550 cm range, reflecting the presence of different N compounds in these manure samples. Fluorescence data revealed five fluorophore components present in the water-extracted organic matter from the manures. We found no clearly distinct value ranges in whole and water-extractable organic matter between the two types of dairy manure with respect to C and N contents and FT-IR and fluorescence spectral features. However, based on the average values, we observed general pattern differences on the effect of organic farming on the manure composition: OD contained less soluble C and N compounds on dry weight basis but more hydrophobic aliphatic groups in whole manure. The soluble organic matter in OD samples contained more stable humic- and lignin-related components and less amino/protein N-related components based on their spectroscopic features. These differences might be attributed to more forage feedstuffs in organic dairy farming management and more protein additives in conventional dairy feedstuffs. Information from this work may be useful in aiding organic dairy farmers in making manure management decisions.

Discourses of on-farm wind energy generation in the UK farming press

As the owners of the majority of land in the U.K., farmers are well placed to contribute to renewable energy targets. Media coverage can both drive and reflect farmers’ views about renewable energy but has been largely unexplored to date. This article uses discourse analysis to examine the evolution of coverage of one form of renewable energy – on-farm wind – in the U.K. farming press from 1980 to 2013. We identified a diverse debate with five major discourses. On-farm wind turbines are alternatively represented as: profitable farm diversification opportunities; producers of clean energy; important for rural development and sources of conflict. Although press coverage predominantly encourages wind energy production, a further discourse advises farmers to ‘Proceed with Caution’. While emphasising images and values which have widespread affinity among U.K. farmers, the press have increasingly employed an economic frame, constructing wind energy generation as a farm diversification strategy. The most recent farming press coverage predominantly encourages an instrumental approach to wind energy, crowding out other (non-economic) rationales and marginalising local community concerns. This appears to reflect the financial orientation of recent policy support (particularly Feed-in Tariffs), and may have long-term costs in enabling sustainable energy production systems.

Environmental risk perception, environmental concern and propensity to participate in organic farming programmes

This paper aims to identify the factors underlying farmers' propensity to participate in organic farming programmes in a Romanian rural region that confronts non-point source pollution. For this, we employ structural equation modelling with latent variables using a specific data set collected through an agri-environmental farm survey in 2001. The model includes one 'behavioural intention' latent variable ('propensity to participate in organic farming programmes') and five 'attitude' and 'socio-economic' latent variables ('socio-demographic characteristics', 'economic characteristics', 'agri-environmental information access', 'environmental risk perception' and 'general environmental concern'). The results indicate that, overall, the model has an adequate fit to the data. All loadings are statistically significant, supporting the theoretical basis for assignment of indicators for each latent variable. The significance tests for the structural model parameters show 'environmental risk perception' as the strongest determinant of farmers' propensity to participate in organic farming programmes.     

External cost internalisation of urban transport: a case study of Dublin

Transport users do not currently pay all costs associated with their transport activities and in particular do not pay the costs they impose on the environment. Case studies on Dublin, Amsterdam, Brussels and London have been conducted to evaluate how best to meet the requirement of the European Commission in its fair and efficient pricing aims in the transport sector, i.e. where transport users are made to pay all costs they impose. The paper presents the results of Do Nothing (DN) and Do Something (DS) scenarios for 2005 where in the latter case each transport user pays for all costs they impose including pollution, noise, accidents etc. The Dublin results, from an economics model used in the study, are examined in detail; the findings are compared with those of parallel studies conducted in the other cities to demonstrate the international relevance of this work. The comparison between the DN and DS scenarios indicates that taxes on all transport modes should be increased substantially, particularly in the morning and evening peak periods. As a result of the price increases, travel demand is reduced. A practical example where transport users could be made to pay for all their costs is road use pricing, i.e. charging individuals for the use of road space. The taxation levels suggested in the DS scenario have been used in a road use pricing trial in Dublin, the results of which were published in O'Mahony, Geraghty and Humphreys (Transportation 27, 269-283, 2000), to see if the reductions in the travel requirements of individuals proposed by the economics model are in fact true. The principles of the work presented in this paper are not only relevant to environmental impact management in the transport sector but can also be applied to other sectors.     

A New Modus Operandi for the Agricultural Economics Profession

Agricultural economics has, until the 1990s, enjoyeda reputation for relevance and usefulness to theagri-food industry and policy-makers. Thatreputation has been jeopardized by a growinginfatuation with models and quantification, and aconcomitant underemphasis placed on many complexproblems and issues of society. An illustrativeexample is explored, using agriculturalactivity-related damage to the natural resourcebase, environment and ecology. Agriculturaleconomists are urged to respond by broadening theirterms of reference and joining forces with otherdisciplines.

Soil arthropods (Coleoptera,Isopoda) in organic and conventional agroecosystems

The relationship between two soil arthropod communities (Coleoptera and Isopoda) in organic and conventional fields was investigated. Soil arthropods were sampled by pitfall traps, and fuzzy set theory and canonical correspondence analysis (CCA) were used for their classification. The study was conducted in: (1) two organic and two conventional vineyards, (2) two organic and two conventional olive groves, and (3) one organic rotation system that involved maize and one conventional maize field. The species composition (three main fuzzy groups) was affected by the crop species and not by the farming system. The CCA placed the rare and unique taxa of soil arthropods at the edges of the diagram and grouped most of them together in relation to soil organic matter and Ca. The same analysis grouped all olive groves and related them to soil organic matter, all vineyards and related them to soil P and, finally, all maize fields and related them to soil N.     

Environmental characteristics of urban-rural farming migrants in the Republic of Korea and their significance for rural sustainability

ABSTRACT

The number of households migrating to agricultural villages has sharply increased in the Republic of Korea (South Korea) since the late 1990s when the Asian economic crisis developed. This study investigates the environmental behaviour and the socio-economic characteristics of urban-rural migrant farming households and provides insights into their significance for rural sustainability in South Korea. The study is based on survey data collected in 2016 from a sample of 166 migrant farming households and 46 native farming households from the Namwon region in South Korea. The migrant farming households are divided into 29 return and 137 non-return farming households. It was found that most non-return migrants are organic farmers, and can be characterised as anti-urban, amenity-pursuing, green, and lifestyle migrants. It is no wonder that they have a strong intent to make their new home an environmentally, socially and economically sustainable place for their children. Thus, appropriate policy measures need to be designed in such a way to facilitate the synergy between the repopulation of rural areas by farming migrants, their uptake of organic farming, their active engagement in community rebuilding, and regional economic development.
