An empirical investigation into the uptake, motivations and constraints and the factors affecting farmers' renewable energy investment intentions

Mbzibain, Aurelian January 2012 (has links)
The rate of adoption of renewable energy (RE) production and associated enterprises onfarms in the UK has been lower than expected suggesting that the UK government’s energy, agricultural and climate change objectives may not be achieved. The aim of this research is to investigate why this is the case by assessing the uptake, motivations, constraints and the factors affecting farmers’ RE investment intentions. Building on extant research literature (institutional theory, social cognition theory, theory of planned behaviour and the resource based view) a novel comprehensive and multidimensional model of entrepreneurial intentions was developed and tested using principal component, path and multivariate regression analysis techniques. Data were collected to test the model through a sample of 2000 farmers in the West Midlands Region of the UK. Of the 393 farmers who responded, 14% adopted RE enterprises, with half of adopters reporting slight to significant improvements in farm business performance in 2009. Solar panels were the most popular of the RE technologies available to farmers, compared to biomass related technologies. The study found that the most influential personal level factors contributing to the adoption of RE and associated technologies were cognitive such as the level of education. Of current 338 non-adopters, 66% might decide to invest in RE technologies over the next five years. For these potential adopters, the study shows that the type of tenure, educational attainment and the type of farm business diversification activity in which a farmer is engaged are the most significant personal and farm business situational factors which influence farmers’ RE investment intentions though contrary to expectation current non-adopters assessed the policy support framework more favourably than current adopters. The explanation of this seems to be connected with timing, in that two very positive and encouraging signals in relation to ii Feed in Tariffs (2010) and the Renewable Heat Incentive (2011) were underway or near introduction before this research took place. The study provides the first empirical evidence of the effects of the multidimensional measures of the country’s institutional profile on farmers’ RE investment intentions. Secondly, it clarifies the distinct role played by national formal and informal institutions on farmers’ investment intentions showing that informal institutions and not formal regulatory factors have a direct effect on farmers’ intentions to invest in RE enterprises. Thirdly, the investigation reveals that social acceptability of entrepreneurship in the RE sector is negatively related to investment intentions and moderates the efficacy of formal government policies in influencing entrepreneurial behaviour in the RE sector. The study concludes that any study that relies only on one type of institution will be making significant prediction mistakes. This study provides further support for cognitive based process models of intentions by showing strong significant positive effects of perceived self-efficacy and perceived desirability of RE enterprises on investment intentions. In fact, the study shows that farmers’ attitudes towards RE explain the highest amount of variance in investment intentions over and above the combined effect of external resource and institutional factors. The study illustrates that perceived self-efficacy and perceived desirability of RE enterprises mediate the effect of the rich set of exogenous variables investigated in this study on investment intentions and argues that policy makers need to focus on improving the regulatory, cognitive and normative institutional environments as a way to improve attitudes towards RE and consequently their intentions to invest in these enterprises.

The Geographic Adaptive Potential of Freight Transportation and Production System in the Context of Fuel and Emission Constraints

Asuncion, Janice Sy January 2014 (has links)
Freight transportation is an integral element of various supply chains and has a complex and dynamical interrelationship with human economic activities. Modern logistical strategies paved way to the current supply chain organisation and logistics network design resulting in a more global economy and huge economies of scale. Recent trends of volatility of oil price have major implications in the movement of commodities across the supply chains. Likewise, climate change issues have presented urgent challenges in reducing carbon emissions for the transport and logistics sector. Pressure on the sector comes from both governments and consumers alike, demanding future sustainability as well as corporate environmental and social responsibility. The original contribution of this research is to investigate the system-wide dynamics of freight transportation and production in the context of supply chains. A theoretical framework called the ‘Geographic Adaptive Potential’ or GAP is built to understand how constraints in energy and emissions affect the production and distribution of commodities. The changes in the supply chain were investigated in four different components, namely a) the potential to shift to less energy and emissions intensive modes for long-haul freight, b) logistical strategies in the last leg of the chain or urban freight and c) local production and distribution, and d) the accessibility of potential customers to the markets. The design of the GAP components is in correspondence with the links of the supply chain. The analyses yielded an evaluation of the adaptive capacity of the freight transport and production system. For long-haul freight, a GIS-based model was created called the ‘New Zealand Intermodal Freight Network’ or NZIFN. It is an optimisation tool integrating the road, rail and shipping network of New Zealand and calculates that minimum time, operating costs, energy and emissions routes between 2 given locations. The case studies of Auckland to Wellington and Auckland to Christchurch distributions of non-perishable products established that even a marginal increase of rail and coastal shipping share produced around 10% reduction in both freight energy and greenhouse gas emissions. In the study of the last leg of the supply chain, the truck trip generation rates of different food stores were investigated. The strongest factors influencing the trip rates to a store are its size and product variation, the latter being a new parameter introduced in the dissertation. It is defined as the total number of brands for 6 chosen commodities commonly found in the stores. The trip rates together with the truck type and distance travelled were used to compute the freight energy usage of the stores. Results revealed that supermarkets consume the most energy for their delivery operations but relative to its physical size, they are more energy efficient than smaller stores. This is due to the utilisation of advanced logistical strategies such as freight consolidation and the effective use of distribution centres. The localised production chapter was explored in the context of Farmers’ markets and their difference with the conventional supermarket distribution system. Using a freight transport energy audit, the energy intensities of both systems were compared. The findings showed that Farmers’ markets were more energy-intensive than supermarkets owing to the low volumes of goods delivered to the market and the lack of freight consolidation effort in the system. The study on the active mode access of potential customers to both Farmers’ markets and supermarkets captured the interplay between freight and personal transport and is the final component of GAP. The results of the ArcGIS based model called ‘Active Mode Access’ or AMA demonstrated that both Farmers’ markets and supermarkets have the same level of accessibility for walking or biking customers. However, the calculations also showed that almost 87% of New Zealanders have no AMA to stores and are at risk for fuel price increase. Finally, the key result of this dissertation is the assessment that there is actually limited adaptive capacity of the freight transport and production system. This is due to network infrastructure and geographical constraints as well as commodity type and mode compatibility and other operational concerns. Due to these limitations, the GAP model assessed that reduction in energy and allowable emissions will ultimately reduce the amount of commodities moved in the system.

Women, work and marriage: A restudy of the Nigerian Kofyar.

Stone, Margaret Priscilla. January 1988 (has links)
Most scholars of female farmers of sub-Saharan Africa have come to agree that the transition from subsistence to market agriculture has hurt women's independent agricultural enterprises and incomes. Research conducted among a group of farmers known as the Kofyar of central Nigeria provides a case study which runs counter to this general consensus. Kofyar women have not suffered a loss of economic or social independence with the introduction of cash-cropping but have in fact embraced the new opportunities of the markets to produce crops for sale independently of their households. The Kofyar farming system as a whole is outlined, and the system of independent production is described within this context. The recent history of the Kofyar is sketched including, most importantly, their migration into an agricultural frontier, the adoption of yams as the primary cash crop, and the evolution of a complex set of mechanisms for mobilizing labor. The role of women in the cooperative labor network and in household labor is described and women's important contributions to all types of labor are linked to their access to labor for their own independent production. One of the basic arguments is that Kofyar women are prospering relative to other African women because their labor has been so crucial to the agriculture of the Kofyar both before and since the introduction of cash-cropping. The other basic argument for Kofyar women's relative success is that they are successfully exploiting the flexibility inherent in their farming system to maximize their own production. The use of intensive techniques such as intercropping and taking advantage of the flexibility in the timing of certain agricultural tasks on their major crops of groundnuts and yams are examples of this strategy. Women have, in other words, evolved a system of independent production which fits around rather than competes directly with male/household farming. The dissertation goes on to place women's independent farming within the broader social system by analyzing differences between women in marriage and childbearing statuses and histories. Regular differences in magnitude of independent production are found between women with contrasting social characteristics (e.g. age, marital status, divorce history, numbers of children). The portrait of the most prosperous woman is sketched. Kofyar women's activities are seen as an essential part of Kofyar development. The system in general has become more prosperous and women as important contributors to that prosperity are also benefiting as individuals from these changes.

Konflikten bakom vildsvinsproblematiken ur ett "Crop-raiding"-perspektiv  : med fokus på svenska lantbrukare

Törnqvist Igelström, Cecilia January 2014 (has links)
Vildsvinstammen har ökat snabbt i södra och centrala Sverige sedan några individer rymde ifrån fångenskap på 1970-talet. Vildsvin har aptit för jordbruksgrödor vilket resulterar i en konkurrens om dessa grödor mellan arterna människan och vildsvin i en s.k. interspecifik konkurrens. Detta utgör i sin tur en konflikt mellan jordbrukare och vildsvin. Denna konflikt verkar även förvärras av jägares förvaltningsmetoder som, enligt lantbrukare, innefattar ett bristande jakttryck och utfodring i för stor skala. Mina resultat kunde visa en konflikt mellan jägare och lantbrukare som även verkar förvärras på organisationsnivå, d.v.s. Jägareförbundet respektive Lantbrukarnas riksförbund (LRF). Vildsvin anses som oönskade av flera respondenter och samtliga tycker att jakt är viktigt. Det finns olika sätt att öka lantbrukares toleransnivå för vildsvin i lantbruk vilket i sin tur kan minska konflikten mellan lantbrukare och vildsvin. Icke-dödliga förvaltningsmetoder bör vara anpassade för vildsvinens fysiska förutsättningar för att minska skador på lantbruk. Dödliga förvaltningsmetoder som jakt bör innefatta en snabb död för vildsvinet, vilket kräver god kommunikation mellan jägare samt tränade hundar i syfte att leta reda på det skjutna vildsvinet ifall det första skottet inte var dödligt. / Wild boar population has increased rapidly in the south and central parts of Sweden since some individuals escaped from captivity in the 1970s. Wild boars have an appetite for agricultural crops resulting in a competition for these crops between the species man and wild boar, in a so-called interspecific competition. This in turn represents a conflict between farmers and wild boar. Management practices by hunters seem to enlarge the conflict, according to farmers there is a lack of hunting pressure and too much feeding. My results could show a conflict between hunters and farmers, which seems to worsen at an organizational level, Association of Hunters and the Federation of Farmers. Wild boar is considered as undesirable by several respondents and all of them agree that hunting is important. There are various ways to increase farmers' tolerance for wild boar in agriculture, which in turn can reduce the conflict between farmers and wild boar. To have an effect, nonlethal control should be appropriate for the physical conditions of wild boar. Lethal control should include a quick death for the wild boar, which requires good communication between hunters and trained dogs in order to locate the shot wild boar in case the first shot was not fatal.

My daddy's farm

Peacock, Frances Louise January 1997 (has links)
My Daddy's Farm is a work of fiction about Clement J. Jones, a man, my great-grandfather, who committed suicide on November 19, 1924. In the early nineteen-twenties, this family man was a well respected, wealthy citizen of his county who--like one-third of his peers--had an active membership in the Indiana Ku Klux Klan. The story is narrated in part by a slightly sympathetic omniscient narrator, but mainly by Hazel Louise Jones, his daughter, who was in her teens when the Klan swept across Indiana in the nineteen-twenties; she was sixteen when her father committed suicide on November 19th, 1924.I have used three variations in this writing, based loosely on the style Gloria Naylor uses in Mama Day. These variations are characterized by the titles of their respective sections: "Our Spring," "Our Farm," "Our Family," and "Our Shame" are all narrated in first person, past tense, by Hazel Jones, Clement's sixteen year old daughter who is speaking as a representative of her family; "Clement J. Jones" and "Hazel Louise Jones" are written in third person, limited omniscient narration; and, "To Margaret," and "To Daddy" sections are present tense, with second person narration from Hazel Jones. Starting with "Our Shame," the story is punctuated by "Document" selections posted at the close of each chapter. These documents are nonfiction: they are news articles taken directly from the Indianapolis Star, the Williamsport Review-Republican, and the Williamsport Pioneer dated 1922, 1923, and 1924; and, they are papers taken out of the "United Klans of America" collection located in the Archives and Special Collections department of Bracken Library, Ball State University.Among sources listed on page 71 of this document, there are a few that were most helpful in providing details about the Indiana Klan: Anti Movements in America, edited by Gerald N. Grob, which reprints "Papers Read at the Meeting of Grand Dragons Knights of the Ku Klux Klan at their First Annual Meeting held at Asheville, North Carolina, July 1923"; and Women of the Klan, by Kathleen M. Blee. Exceptionally helpful was William Lutholtz's Grand Dragon, a well researched work of non-fiction about D.C. Stephenson's rise to power in the Indiana Klan and the development of the Indiana Klan.Three works of fiction especially provided creative direction for this thesis: Mama Day, by Gloria Naylor; Alias Grace, by Margaret Atwood; and, In the Lake of the Woods, by Tim OBrien. / Department of English

The family farm through a succession lens : towards understandings of contemporary practices and processes

Williams, Fiona Jayne January 2010 (has links)
This study examines change in the family farming sector through the lens of succession. It explores empirically the succession expectations and intentions of farmers and their children in a changing contextual landscape. The research is underpinned by two theoretical concepts: the ‘farm adjustment strategy’ facilitated the development of structural reference points in respect of the family farm business and household; and application of tenets of van der Ploeg’s (1994) ‘styles’ work enabled analysis of structural change in the farm business to be viewed through a qualitative succession lens. A ‘pragmatist’ mixed-methods approach comprised a farmer survey and next generation in-depth interviews. The analytical approach accommodated issues of temporality and facilitated the linkage and study of multiple components of change. It was found that immense variability exists in terms of how succession is managed in practice. The structural characteristics and capacity of the farm business clearly impact upon succession choices and positions, but intrinsic drivers also have a very significant bearing on succession and its potential outcome. The research revealed three broad outcomes of next generation succession intention, each forming the basis of a succession style: a desire and intention to succeed to the family farm, reflected in more traditional succession modes; an intention to leave the family farm, thus opting out of farming per se; and part-time succession, characterised by off-farm professional work, flexibility and a lifestyle preference that encompasses aspects of farming and non-farming worlds. The findings presented in this thesis suggest that, through succession, forms of farm management and operation are evolving. Family farming entities are adapting and becoming increasingly heterogeneous. Through a contemporary succession lens, the notion of the family farm now comprises an assortment of family-owned and family-managed businesses with an array of diversified business, amenity and farming interests.

Urban Farm

Mohammed, Anisa A. 01 January 2007 (has links)
According to Michael Pollan's article in Mother Jones Magazine, "The typical fruit or vegetable on an American's plate travels some 1,500 miles to get there, and is frequently better traveled and more worldly than its eater" (Pollan 38). The majority of citizens living in or near metropolitan centers rarely come in contact with produce pre-barcode; that is, produce still connected to the earth or not yet processed for mass distribution and consumption. This is especially the case in urban settings where land is at a premium and is valued more for residential and commercial purposes than for food production. In the case of U.S. cities, though we produce sufficiently to feed our population, the majority of produce consumed is grown outside of state lines if not entirely outside of the country. "In 2004, the U.S. exported nearly $20 million worth of lettuce - over 3/4 of it grown in California - to Mexico. The same year, it imported $20 million worth of Mexican lettuce" (Pollan 43). It is far more likely that urbanites seek references from their car mechanics and tailors than from producers of the food they consume. Locally grown and consumed food has several quality-of-life enhancing attributes, most importantly providing fresher, more nutritious produce with a known history, increased self-sufficiency with respect to food, and reduced environmental impact caused by reduced inter and intra-national transportation.
