7 pages, Agricultural extension is the medium through which external agricultural technologies have been transferred to and transplanted in Africa to improve agricultural performance. Over a period of close to a century, different agricultural extension models have been proposed but their structure and content has virtually been the same: top-down, linear, non-participatory transfer of technology with no feedback loops for reverse diffusion. This presumably explains the poor performance of Africa’s agriculture and the scale of food security challenges facing the continent. In this review paper, we trace the history of agricultural extension and examine various agricultural extension delivery models to identify their major strengths and weaknesses, using Ghana and Burkina Faso as case studies. We then review the most recent literature in the field about the philosophy, scope, content, delivery, and outcomes of agricultural extension. The conclusion that agricultural extension has consistently remained out of sync with the needs and aspirations of stallholder farmers was reached. Smallholder farmers are now calling for new agricultural extension delivery models that are truly farmer-led, indigenous knowledge-based, context-specific, culturally-relevant and environmentally-sustainable to guarantee efficient farming systems into the future.
15 pages, The purpose of this study was to assess the effectiveness of extension services on capacity building of smallholder livestock farmers in Midvaal Local Municipality, Gauteng Province, South Africa. A simple random sample technique was used to select the participants, so that individual farmers in the study population could have an equal chance of being selected in the study. A structured questionnaire was used to collect data from 148 smallholder livestock farmers. The data gathered from participants was coded and captured in Microsoft Excel. Descriptive statistics such as frequency counts, mean, percentages, standard deviation, ranking order, and inferential statistics such as binary logistic regression were used to analyse the data. Results showed that technical farm visits (M = 3.3, SD = ±1.36) and informal training (M = 3.2, SD = ±1.31) were effective extension methods. Furthermore, they showed that extension services were less effective at enabling farmers to penetrate formal markets (M = 2,0 SD = ±1.06) and access finance (M = 1.9, SD = ±1.01). The binary logistic regression model revealed that gender and farming status were the main variables that significantly (P<0.05) influenced smallholder livestock farmers’ access to extension services. It was concluded that extension services in the study area were playing a major role in the capacity building of smallholder livestock farmers.
15 pages, Cover crops—crops grown primarily to protect and improve soil—are widely considered to be an important component of sustainable agricultural systems because their use can provide multiple ecosystem services without compromising yields over time. Specialty crops—fruits, vegetables, and horticultural crops—are increasingly important to US agriculture and food security and uniquely vulnerable to climate-related problems that cover crops can help to address. Yet far less research has been conducted on cover crop use by farmers who grow mainly specialty crops, compared to the much larger body of research on farmers who principally grow row crops like corn (Zea mays) and soybeans (Glycine max). In this study, we draw on survey data from a stratified, random sample of 881 specialty crop growers in Michigan and Ohio to accomplish two main goals. First, we seek to characterize cover crop use among this important group of farmers, focusing on types of cover crop used and use of multiple types. Second, we examine the relationship between cover crop use on vegetable and fruit farms and key social and economic factors, with particular attention to farmers’ environmental values, adherence to organic principles, and sources of information. According to survey results, cover cropping is more likely when farmers (1) manage certified organic (p < 0.01) or organic-in-practice (p < 0.05) farms; (2) report being influenced by private crop consultants (p < 0.01); (3) attach high importance to agri-environmental goals (p < 0.01); and (4) grow vegetable crops instead of or in addition to fruit crops (p < 0.001). No relationship was found to exist between cover cropping and farmers’ concerns about climate-related risks, education level, or perceived self-efficacy. We conclude by suggesting that the importance of structural factors to farmers’ decisions about cover crops should not be underestimated. Promoting and strengthening the market for organic food may be the most direct pathway toward increasing the number of farmers who use cover crops. Historically important entities in agricultural networks, including cooperative extension and conservation nongovernmental organizations, might enhance their impact on cover crop use by forming new partnerships with private crop consultants.
20 pages., Given the multi-benefits, enset cultivation has been continuously underutilized in Ethiopia. We assess best practices, processing technologies, environmental maintenance, multi-benefits of enset and its potency in hunger reduction in Ethiopia by reviewing evidence on good farm practices, improved technologies, sustainability, hunger reduction, inputs cost, and yields advantage of enset. The review results identify those best practices that optimize enset yield, technologies that facilitate extension services, processing and food qualities of enset. Moreover, we find that enset is a first-rated climate-smart crop, superior hunger solution because of its apparent capability to endure long periods (more than 5 years) of drought, highest yield, energy food supply, and costs advantages. In contrast, its long-period maturity, cultural perceptions, and little development policy attention given to enset limit its expansion. Therefore, exploring and creating universal access mechanism of early maturing and high-yielding varieties, processing technologies and mobile-based advices, involving best practices of enset in regular agricultural extension services, changing social perceptions optimize enset yield and production thereby it contributes environmental sustainability and cuts hunger challenges.
19 pages, The adoption of digital technologies is expected to impact the social sustainability of agriculture, in particular in the case of small and mid-sized family farms in Western Europe. Goal of this research was to assess these impacts, however widely accepted impact assessment schemes of social sustainability are missing. Against this background, a qualitative, two-stage Delphi survey was conducted in order to identify relevant impact categories of the adoption of digital technologies in family-operated small-scale farms of South-West Germany. The participating experts stated, for example, that the adoption of digital technologies on the farm could mean that new business models can be based on the use of digital technologies. However, they also stated that digital technology could overburden farmers, which could hinder digitization in this sector as a whole. Data protection and data security were also issues ranked highly important by the participants in the Delphi Process.
12pgs, COVID 19 has exacerbated and underscored structural inequalities and endemic vulnerabilities in food, economic, and social systems, compounding concerns about environmental sustainability and racial and economic justice. Convergent crises have amplified a growing chorus of voices and movements calling for new thinking and new practices to adapt to these shifts, mitigate their impact, and address their root causes through far reaching changes in social and economic life and values, including breaking with the free market paradigm. In the face of a historic choice between transition or multiple systems collapse that deepen injustice and threaten planetary survival, I make the case for expanding on liberatory tendencies in Extension programs to build capacities for response-ability to transition toward more just and sustainable futures.
24 pgs, Increasing interest in farmers’ local soil knowledge (LSK) and soil management practice as a way to promote sustainable agriculture and soil conservation needs a reliable means to connect to it. This study sought to examine if Visual Soil Assessment (VSA) and farmer workshops were suitable means to engage, communicate and preserve farmers’ LSK in two mountainous communes of Central Vietnam. Twenty-four farmers with reasonable or comprehensive LSK from previously studied communes were selected for the efficacy of VSA and farmer workshops for integrating LSK into a well-accepted soil assessment tool (VSA). In field sites chosen by the farmers, VSA was independently executed by both farmers and scientists at the same time. Close congruence of VSA scores between the two groups highlighted that farmers could competently undertake VSA. Farmers’ VSA score was compared with their perception of field’s soil quality. For the majority of farmers’ perception of soil quality was consistent to their VSA score (62.5%), while the remainder perceived their soil quality was lower than their VSA score. For most farmers their assessment of soil quality using VSA valued their LSK, and the two measures were well aligned. Soil colour and presence or vulnerability to erosion were common soil characteristics mentioned by farmers and affected the final VSA score. Farmers’ participation in VSA and workshops strengthen farmers’ confidence in their LSK and provided guidance on the impact of their soil management on soil improvement and conservation.
16pgs, Humanity's growing appetites for food and energy are placing unprecedented yield targets on our lands. Chasing those ever-expanding land intensification targets gave rise to monocultures and sharpened the divide between food and energy production groups. Here, we argue that this does not have to be a zero-sum game if food and energy can be co-generated in the same land. Co-generation can lead to sustainable intensification but requires a paradigm shift in the way we manage our resources, particularly light. Using an extended model of plant photosynthesis and transpiration, we demonstrate how plants react to different incident light spectra and show that manipulating light could be effective for boosting land and water efficiencies, thus potentially improving soil health. This knowledge can possibly unlock the real potential of promising modern agricultural technologies that target optimization of light allocations such as agrivoltaics. This study suggests that the blue part of the light spectrum is less efficient in terms of carbon assimilation and water use and could be more effectively used to produce solar energy, while the red part could efficiently produce biomass. A sensitivity analysis to the most important crop and environmental variables (irradiance, air temperature, humidity, and CO2 concentration) shows that plant response to different light treatments is sensitive to environmental boundary conditions and is species-specific. Therefore, further research is necessary to assess which crops and climates are more suitable to optimize the proposed food-water-energy nexus.
11 pages, The world population is increasing in a disquieting rate while the quantity of food to gratify this snowballing human population is an annoyance to agrarian scientists and policymakers around the globe. Today's population is snatching natural resources from the future which can endanger the future generation's right to have nutritious food and clean air. The causes for this challenge can be enumerated and listed out, but singled out as lack of and/or poor implementation of novel approaches and practices for sustainable agriculture. Some of the novel approaches are but not limited to climate smart agriculture (CSA), organic farming, biodynamic agriculture, sustainable intensification and regenerative agriculture; and novel practices as integrated farming system (IFS), precision agriculture, integrated nutrient management (INM) and integrated pest management (IPM). The adoption of these approaches and practices has been proven to safeguard agricultural sustainability.
7pgs, Agricultural subsidies are an important factor for influencing food production and therefore
part of a food system that is seen as neither healthy nor sustainable. Here we analyse options
for reforming agricultural subsidies in line with health and climate-change objectives on one
side, and economic objectives on the other. Using an integrated modelling framework
including economic, environmental, and health assessments, we find that on a global scale
several reform options could lead to reductions in greenhouse gas emissions and improvements in population health without reductions in economic welfare. Those include a repurposing of up to half of agricultural subsidies to support the production of foods with beneficial
health and environmental characteristics, including fruits, vegetables, and other horticultural
products, and combining such repurposing with a more equal distribution of subsidy payments globally. The findings suggest that reforming agricultural subsidy schemes based on
health and climate-change objectives can be economically feasible and contribute to transitions towards healthy and sustainable food systems
