Abstract:

This paper reviews options for the design and analysis of on-farm experiments. It covers both older approaches that have been popular since the Green Revolution, and more recent developments made possible by the availability of online monitoring systems as used in precision farming. The roles of randomisation as well as of geostatistical methods of analysis for these kinds of experiments are critically discussed. Two case studies are provided for illustration.

Abstract:

SUMMARYSmallholder farmers in Malawi are faced with the challenge of managing complex and dynamic farming systems while also adapting to change within volatile agroecological conditions. Moreover, management decisions are influenced by a combination of local knowledge, expert recommendations and on-farm experimentation. Although many smallholder farmers actively experiment with new crops and technologies, little is known about the prevalence of experimentation or the types of experiments farmers conduct. This study examined the decision-making processes of experimenting farmers to explore the drivers of on-farm experimentation. Using a mixed-methods design that incorporated field observations, survey data and in-depth interviews, we identified numerous examples of experiments with new crops, varieties and techniques that had been executed either independently or through participation in an agricultural development project. Results of quantitative and qualitative analysis reveal that smallholder farmers in Malawi across a range of socioeconomic characteristics are inclined to experiment, and gender roles in agricultural experimentation vary widely. While experimental methods differ between farmers, there are commonalities in the drivers of experimentation, including adapting to climate change, improving soil health, improving nutrition and generating income. Smallholders have a great capacity for experimentation, and their knowledge, experience, preferences and priorities – if properly understood and incorporated – could ultimately benefit both future agricultural development projects and their participants.

Abstract:

The aims and design features of historic long-term experiments are discussed and modern perceptions are presented of long-term studies to address sustainability and research impact in farming communities. A research strategy is proposed combining on-station and on-farm research whose results influence dynamically the directions of the component studies. Guidelines are given for choosing well-controlled designs, appropriate data and sampling procedures and for maintaining quality control in data collection and indicator formation over anticipated lengthy periods of time.

Abstract:

An investigation on integrating horti-pastoral systems into prevalent farming systems in central India was undertaken by the team of scientists in Bundelkhand region of India. The preference of fruit species was done through matrix ranking by the farmers and experiments conducted at their fields. The study indicated that majority of farmers following mixed farming, growing crops and rearing farm animals for their livelihood. The maize, groundnut, sesame, black gram, sorghum and pearl millet were found mostly grown in kharif season and wheat, gram, lentil in rabi. However, the mono cropping is still in practice in the area. The acute shortage of quality green fodder has been noticed during summer. The fresh stalk and stover of maize, sorghum and pearl millet in kharif, straw of wheat, gram and green fodder of Egyptian clover was found main source of fodder in winter. The survival of animals managed by the farmers but their production level was much below to their potential. Mostly the farmers have large families as well as animals, small holdings and comparatively better literacy. The farmers did not utilize the land earlier for any purpose, now utilizing and producing quality fodder. The production from fruits expected in succeeding years will contribute additional source of income in the years to come and improvements of degraded lands.

Full text

Abstract:

Transforming the Brute addresses the ethical acceptability of creating painless animals for usage in biomedical experimentation. In recent decades the possibility of creating genetically decerebrate animals or AMLs for human ends has been discussed in scientific, academic, and corporate communities. While the ability to create animals that cannot feel, experience, and are more plant than animal remains science fiction, biomedicine may now be able to eliminate or significantly reduce the capacity to feel pain and nociception through genetic engineering. With this new technology comes the opportunity to vastly increase the welfare of animals used in biomedical experimentation, yet this possibility has largely been ignored by the scientific and academic community. This work seeks to reveal the moral necessity of creating painless animals for usage in biomedical experimentation for animal welfare ends. Intrinsic objections relating to animal integrity, rights, companionship, the alteration of telos, humility and virtue are considered. The benefit of eliminating nociceptive pain in experimental animals is addressed, and differences are examined between biomedical experimentation and other usage of animals for human ends which makes the proposed creation of painless animals ethically unique. Finally, an argument is presented for the moral necessity of replacing normal animals with painless animals in biomedical experimentation with consideration given to genetically decerebrate animals.

Abstract:

Abstract A project under the Farmer Innovation Programme (FIP) that aimed to adapt Conservation Agriculture (CA) among grain farmers in South Africa was implemented in a commercial farming area of the North West Province. The following on-farm, collaborative-managed trials produced key findings concerning: (i) plant population densities (high versus low) under CA; (ii) conventional crop systems versus CA crop systems; (iii) the testing and screening of cover crops; (iv) green fallow systems for soil restoration; and (v) livestock integration. Key results from these trials were that the yield of maize was significantly higher under high-density no-till (NT) systems compared to the normal NT systems. The yield of maize in local conventional systems was lower than the yield in NT systems tested on three farmer-managed trials. The screening trial assisted in testing and learning the suitability and the different attributes of a range of cover crops in that area. Cover crop mixtures used as a green fallow system with livestock showed that CA can facilitate the successful restoration of degraded soil.

Abstract:

Abstract While Effective Altruism helps influencers do good by supporting farmed animal causes, it has been woefully inadequate in guiding strategies within the farmed animal advocacy space. Moreover, Effective Altruist funding has generated troubling consequences. Focusing on short-term incremental improvements, advocates are taking their eyes off the prize: the end of factory farming. The farmed animal movement has more investments than ever going into corporate campaigns, but meaningful returns have been diminishing. While advocacy groups receive significant funding for incremental improvements, other promising strategies tied to a bolder vision for systemic change remain underfunded. We don’t need to accept the factory farm as an inevitable evil and content ourselves with making it “more humane.” Funders can do enormous good within their lifetimes, but only through a willingness to confront complex social challenges. The movement needs funders with fearlessness, an entrepreneurial spirit of experimentation, and the moral imagination to end industrial farming.

Abstract:

“The outstanding scientific discovery of the twentieth century is not television, or radio, but rather the complexity of the land organism,” wrote my father in Round River. As he was hinting, we can locate many of the parts, but how these fit together in the land organism was another matter. Finding the native plant species would be a good start. To reunite some of these came next. The work of our family was creative in its own right: figuring out what conditions these species needed, including by experimentation. Essential to that is appreciating how this landscape got its form—what processes have worked on it and with what results. This much helps us with our understanding of the setting and the soils—what I would call the lay of the land. In the work to restore old habitats and old vegetation types, it is really useful and interesting to know something of the land history, ancient and recent. As Mary Austin wrote, “To understand the fashion of any life, one must know the land it is lived in and the procession of the year.” The Shack experience involved both of these elements. When you live in an area, a natural question that arises is how the landscape got the way it is. What forces shaped it, and over what periods of time? In the Shack area, two different prominent ridges (about twenty-five feet in height) are oriented perpendicular to the Wisconsin River. One is the north-south ridge just west of the Shack—the Sand Hill/Clay Hill ridge. The other is the north-south ridge downstream from Gilbert’s farm; it is the ridge on which the Leopold Center is built. At the point where the river cuts the nose of that ridge (Barrows Bluff) are a great number of large boulders and clay. The Sand Hill site also has an enormous boulder on it. Both have sand on top near the river. I wondered how ridges like these formed in the first place. Then I read the report by Robert Dott and John Attig about the history of the glacial ice lobes in Wisconsin.

Full text

Abstract:

The agricultural community/farmers are struggling to obtain higher rate of yield due to lack of poor knowledge about the soil and water nutrients and suitability of the organic crop for the soil. Most of the farmers use excessive chemical fertilizers in-order to increase productivity of their yield, without aware of side effects. The excess usage of chemical fertilizers by the farmers will have impact on the quality, fertility, and salinity of the soil. To overcome these issues and to promote Digital Agriculture concept we propose an IoT enabled sensor system for monitoring soil nutrient [NPK] and pH of irrigation water to reduce the manual laboratory method of testing and get the results via mobile application and to promote organic farming in the agricultural field. Smart organic farming based mobile application will further process these nutrients value to predict and suggests the suitable crop to grow and the usage of appropriate amount of fertilizer to maintain the soil fertility there by achieving optimum usage of chemical fertilizer because continuous and wrong usage of these chemical fertilizer have a harmful effect not only on soil but also on crops, we consume leading to unhealthy human life. The proposed mobile application also helps in establishing the connection between farmers and Agricultural Produce Market Committee (APMC) in order to avoid fragmentation of profit shares and attain Pricing uncertainty and marketing of the yields by avoiding the middle man. APMC is a state government body which ensures safeguard to the farmers from exploitation by large retailers and suggest the kind of crop to be grown with organic farming. India is well known to produce organic fertilizer which is produced by the waste of slaughterhouses, plant and animal residues, biological products and other natural resources. Thus, the proposed work helps the farmers in adopting stress-free organic farming practice by self-testing their field soil parameters for generating quick soil analysis reports and also helps in connecting with APMC to know the suitable crop for their agriculture land based on the soil and water analysis (SWA) report, dispensing the required amount of organic fertilizer to the soil based on soil and water nutrients analysis using IoT enabled sensor, funding/insurance to the crops in case of occurrence of unpredictable natural disaster in future and direct marketing facility without middle man and maintain sustainable agriculture. In the present era, the industry is at 5.0 levels but agricultural production is still at 2.0 levels. In this chapter a methodology for sustainable agriculture and increase the organic yield of the organic farming using the mobile and IoT technological approaches is presented. A former can obtain the advice and other information for growing the organic crop, organic certification, pricing for the organic yield, selling and other activities by using mobile application in his/her local language. By the proposed work with the ease of mobile application the farmers can perform self-test of their field parameters for generating quick soil and water analysis report, predicts and suggest the suitable organic crop, obtaining the suitable pricing by the APMC and organic certification and agreement to meet the sustainable agriculture. Further the soil fertility of the organic farm can be monitored using IoT enabled sensors which are remotely connected with the mobile application. The experimentation is performed at different agriculture fields with organic farming at six geographical separated villages at Bagalkot district of Karnataka state, India. The different agricultural lands with variety of soil samples is tested to measure the soil parameter such as moisture, temperature, humidity and NPK nutrient values. The pH value of the irrigation water is also determined including borewell, pond, rain, river water etc. available in the reservoirs and promising sustainability in the organic yield is obtained.

Abstract:

This paper aims to analyze the process of knowledge creation, more specifically the four modes of knowledge conversion, on agricultural producers or farmers in Brazil, using the theoretical model of Nonaka and Takeuchi (1997). The research is an exploratory-descriptive study of a qualitative nature. The study demonstrated that for new knowledge to be created in the rural properties researched, at least three conditions should be considered essential: when people and their emotions are associated with work activities; when the personal relationships contribute to the improvement of the rules, the management and the policies of the farm; and when the knowledge is associated with experimentation and external incentives. For the creation of new knowledge to occur, information and insights from different sources, mainly, from co-operative, are also necessary to start the process of change in mental model and for the learning of people, groups and organizations in agribusiness.

Rapid detection of food borne pathogens and non-pathogens in fresh produce using FT-IRS and raman spectroscopy. United States Department of Agriculture, October 2004. http://dx.doi.org/10.32747/2004.7587221.bard.

Full text

Abstract:

Rapid detection of pathogens and hazardous elements in fresh fruits and vegetables after harvest requires the use of advanced sensor technology at each step in the farm-to-consumer or farm-to-processing sequence. Fourier-transform infrared (FTIR) spectroscopy and the complementary Raman spectroscopy, an advanced optical technique based on light scattering will be investigated for rapid and on-site assessment of produce safety. Paving the way toward the development of this innovative methodology, specific original objectives were to (1) identify and distinguish different serotypes of Escherichia coli, Listeria monocytogenes, Salmonella typhimurium, and Bacillus cereus by FTIR and Raman spectroscopy, (2) develop spectroscopic fingerprint patterns and detection methodology for fungi such as Aspergillus, Rhizopus, Fusarium, and Penicillium (3) to validate a universal spectroscopic procedure to detect foodborne pathogens and non-pathogens in food systems. The original objectives proposed were very ambitious hence modifications were necessary to fit with the funding. Elaborate experiments were conducted for sensitivity, additionally, testing a wide range of pathogens (more than selected list proposed) was also necessary to demonstrate the robustness of the instruments, most crucially, algorithms for differentiating a specific organism of interest in mixed cultures was conceptualized and validated, and finally neural network and chemometric models were tested on a variety of applications. Food systems tested were apple juice and buffer systems. Pathogens tested include Enterococcus faecium, Salmonella enteritidis, Salmonella typhimurium, Bacillus cereus, Yersinia enterocolitis, Shigella boydii, Staphylococus aureus, Serratiamarcescens, Pseudomonas vulgaris, Vibrio cholerae, Hafniaalvei, Enterobacter cloacae, Enterobacter aerogenes, E. coli (O103, O55, O121, O30 and O26), Aspergillus niger (NRRL 326) and Fusarium verticilliodes (NRRL 13586), Saccharomyces cerevisiae (ATCC 24859), Lactobacillus casei (ATCC 11443), Erwinia carotovora pv. carotovora and Clavibacter michiganense. Sensitivity of the FTIR detection was 103CFU/ml and a clear differentiation was obtained between the different organisms both at the species as well as at the strain level for the tested pathogens. A very crucial step in the direction of analyzing mixed cultures was taken. The vector based algorithm was able to identify a target pathogen of interest in a mixture of up to three organisms. Efforts will be made to extend this to 10-12 key pathogens. The experience gained was very helpful in laying the foundations for extracting the true fingerprint of a specific pathogen irrespective of the background substrate. This is very crucial especially when experimenting with solid samples as well as complex food matrices. Spectroscopic techniques, especially FTIR and Raman methods are being pursued by agencies such as DARPA and Department of Defense to combat homeland security. Through the BARD US-3296-02 feasibility grant, the foundations for detection, sample handling, and the needed algorithms and models were developed. Successive efforts will be made in transferring the methodology to fruit surfaces and to other complex food matrices which can be accomplished with creative sampling methods and experimentation. Even a marginal success in this direction will result in a very significant breakthrough because FTIR and Raman methods, in spite of their limitations are still one of most rapid and nondestructive methods available. Continued interest and efforts in improving the components as well as the refinement of the procedures is bound to result in a significant breakthrough in sensor technology for food safety and biosecurity.

Abstract:

This report explores the potential of Urban Agriculture (UA) to enhance food security, improve resource efficiency, and promote smart, resilient, and circular cities. The discussion is framed within the scope of the Horizon 2020 project ‘Sino-European Innovative Green and Smart Cities’ (SiEUGreen) which explored different pathways to turn waste into resources for growing food in cities through the combination of different technologies. These technologies were tested in five showcases: Campus Ås, in Ås, Norway; World Gardens and Brabrand Fællesgartneriet community gardens in Aarhus, Denmark; Turunçlu greenhouse in Atakya, Turkey; Sanyuan Farm, in Beijing, and Futiancangjun residential area in Changsha, China. The insights and knowledge gained with these showcases were the basis to discuss the barriers and drivers of UA in the transition to more sustainable and resilient circular cities, across five aspects (1) environmental, (2) technological, (3) economic, (4) social and cultural and (5) regulatory and institutional issues. The results suggest that city food provision and UA systems can be designed considering circular economy regenerative cycles, but it is important to promote local research that can highlight policy solutions to address context-related barriers and limitations. Among the main lessons learned across the different aspects, we highlight: - The need for more evidence-based research, clear monitoring tools and evaluation/assessment of the different UA typologies and their impact on the environment, society and economy; - The implementation of innovative technological developments that support and promote UA for reduce; reuse, recycle/recover resources require more experimentation, large-scale tests and validation both concerning their efficiency, positive environmental impacts, as well as economic viability; - The need for high investments, difficulties accessing financial support, underdeveloped business case for circular resource models, and limited recognition of the positive and indirect economic, environmental benefits of UA are among the main barriers that limit the uptake of agriculture in cities; - Despite the significant role UA can play in advancing a circular economy (e.g., by supporting sustainable local food systems, promoting community resilience and reducing waste), behaviour and cultural barriers were found to have a deep impact when fostering a closed-loop approach to UA, especially concerning overcoming prejudice against waste as a resource, - Local governance and public policy play a central role in framing and supporting UA (e.g., incentives, funding, regulatory frameworks) as a pathway that enables close loops in cities.
