The Role of Anaerobic Digestion in Achieving Soil Conservation and Sustainable Agriculture for Sustainable Development in the UK

The subjection of soils to degradation directly and indirectly from rising world food demand and resultant intensified agricultural production, population growth, and climate change, demand that soils are better protected. The role of AD in addressing this challenge is examined using a pragmatic research paradigm and the questions: How can we raise awareness of AD in the UK? What factors motivate and hinder farmers towards adopting improved technology and sustainable agricultural practises? What is the perception of farmers about soils? To what extent does sustainable agriculture incorporate soil conservation in theory and practice? What role can legislation and policies play in AD adoption in the UK? The research was in two phases; qualitative and quantitative. The qualitative phase involved interviews with 21 AD stakeholder in the UK using electronic mail. The stakeholders who were divided into groups according to their expertise, were interviewed to explore their views on the areas of focus in the UK strategy and action plan regarding raising awareness of the technology, soil conservation, sustainable agriculture and sustainable development. Thematic analysis of interview data was carried out using MAXQDA 11 statistical software. The quantitative phase involved an online survey of 283 UK farmers aided by Yellow Pages directory for UK, Natural England directory, Twitter and electronic mail. Using SPSS 22.0 statistical software, the Chi square test was used to check for relationships between the variables measured at 95% confidence level (p<.05). Relationship strength was measured by means of Cramer’s V and Phi values. Answers to the 1st research question showed that: aligning AD with sustainable development goals, community AD and localism, small AD plants, provision of an available market for AD products, building UK skills and diversifying biogas use from AD are positive options for raising awareness of AD. Response to 2nd research question revealed: significant relationships between interests in agricultural technology and gender, level of education, and farm size; between knowledge of what AD is and gender, level of education and farm size; between interest in AD and age; between willingness to invest in AD if it improved soil properties and farm ownership; and between organic farming practice and age, farm type and farm size. Responding to the third research question, farmers’ describe soils in abstract, scientific, physical attribute and functional terms; awareness of soil benefits other than crop production was significantly related to age, and farm ownership; educational level was significantly related to familiarity with soil conservation, and opinion on whether soil should be protected like other natural resources. Findings regarding the 4th and 5th research questions showed: limited understanding of soil matters as a key challenge that has restricted the priority given to soil conservation, while level of education, knowledge of soil conservation and sustainable development and understanding of sustainable agriculture were also identified as influencing factors; digestate from AD is the main benefit viewed to contribute to soil conservation; finance, policy and legislation, low awareness and understanding, lack of feedstock and market, land use conflict and inefficiency of AD plants were identified as barriers to AD in the UK; promoting AD, providing finance, minimizing bureaucracy and simplification of AD systems are options for promoting AD adoption. This thesis also documents the implications of these findings for knowledge, policy and practice, and based on these recommendations are made, some of which are: better engagement of farmers in policy development for AD and soil management; use of small AD plants, demonstration, networking and training for AD adoption; promote soil conservation in theory and practice; and provision of enhanced support for owners, potential investors and farmers through incentives, simplified planning approval process, and available market for AD product

Raising awareness of anaerobic digestion in the UK - Views of key stakeholders

This is the open access PDF version of an article published in Journal of Environmental and Ecology© 2014.Meeting rising energy demand and sustainable development goals at the same time is a major challenge for policy makers in the 21st century. The situation is further stressed by a rising world population, climate change, natural disasters and food security concerns. Renewable energy technologies such as anaerobic digestion (AD) proffer one solution for policy makers to overcome some of the challenges to sustainable development. The technology has been widely adopted in some parts of Europe (e.g. Germany, Denmark, Austria and Sweden), the United States and also parts of Asia and Africa. However in the United Kingdom (UK), the technology is under-developed, as was recognised in its anaerobic digestion strategy and action plan of 2011. This study focused on identifying options for raising awareness of AD technology in the UK. 21 key stakeholders divided into groups according to their expertise, were interviewed to explore their views on the areas of focus in the UK strategy and action plan regarding raising awareness of the technology. The results revealed that aligning AD with sustainable development goals, community AD and localism, small AD plants, provision of an available market for AD products, building UK skills and diversifying biogas use from AD are positive options for raising awareness of AD in the UK. Challenges to these options and possible solutions to the challenges were also identified and discussed

The role of anaerobic digestion in achieving soil conservation and sustainable agricultural development in the UK.

Anaerobic digestion represents one form of renewable energy technology but has many wider benefits. This paper reviews the processes involved in anaerobic digestion, the type of systems in place and the use of digestate to improve soil quality. A case is made for the technology in the UK in the context of soil conservation and sustainable agricultural production. Its broader contribution to sustainable development in the United Kingdom is also considered. Low levels of awareness of the benefits of anaerobic digestion, poor access to funds, inadequate incentives, an unfavourable legislative and policy framework for the technology, limited application of digestate for agricultural purposes and the need for further research on digestate use are identified as key factors hindering uptake of the technology. Anaerobic digestion is presented as a technology that can support soil conservation and sustainable agricultural development while also generating both energy and income, enhancing waste and nutrient recycling and promoting environmental protection

Farmers’ perception of soil: Implications for soil conservation and sustainable agriculture in the UK

This document is the Accepted Manuscript version of a published work that appeared in final form in Global Journal of Agricultural Research. To access the final edited and published work see http://www.eajournals.org/journals/global-journal-of-agricultural-research-gjar/We identify UK farmers' perception of soil, awareness of soil in terms of how they describe it, their awareness of its benefits other than for crop production,their familiarity with soil conservation and their opinions on soil protection and the value of organic fertilizers. Data were collected with the aid of social media using both Twitter and electronic mail to deistribute a survey link to farmers,UK yellow pages, Natural England directory and Twitter were used to search for farms. Data were analysed using SPSS and Wordle. Results showed that farmers' describe soils in abstract, scientific, physical attribute and functional terms. Awareness of soil benefits other than crop production was significantly related to age, and farm ownership. Educational level was significantly related to familiarity with soil conservation and opinion on whether soil should be protected like other natural resources. The implications of these results for soil conservation and sustainable agriculture are discussed and used as the basis for policy recommendations

Farmers’ Interest in Agricultural Technology and Organic Farming: Implications for AD Adoption and Sustainable Agriculture in the UK

We identify the factors that attract UK farmers towards a given technology, their interest in agricultural technology and their practice of organic farming. The implications of this on the adoption of anaerobic digestion (AD) in the UK and sustainable agriculture are also discussed. Farmers were contacted by means of online survey, aided by yellow pages directory, Natural England directory, Twitter and electronic mail. A total of 283 farmers participated in the survey. The Chi square test was used to check for relationships between the variables measured at 95% confidence level (p<.05). Relationship strength was measured by means of Cramer’s V and Phi values. The results showed several significant relationships among variables, including relationship between interests in agricultural technology and gender, level of education, and farm size; between knowledge of what AD is and gender, level of education and farm size; between interest in AD and age; between willingness to invest in AD if it improved soil properties and farm ownership; and between organic farming practice and age, farm type and farm size. Results also showed a significant presence of female farmers, young farmers (< 30 years old), high level of education among UK farmers, and low level of organic farming practice. Areas for future research and recommendations based on the results are presented in the conclusion
