Organic agriculture has the potential to provide improved livelihood opportunities, increased income and social benefits for resource-poor small-scale farmers. It has thus become a popular strategy ...for economic development and poverty reduction in many areas of the global south. However, there has been limited empirical research regarding the actual benefits of certified organic production, particularly when organic is combined with fair trade certification, and for small-scale farmers who are not engaged in coffee or banana production. Further research is needed to demonstrate experiences of farmers under diverse socioeconomic conditions, organizational contexts and degrees of market access. To address these gaps, two surveys of certified organic and fair trade tea producers in China and Sri Lanka were undertaken to investigate the contributions of organic crops to the household economy. In both cases, organic production required lower investment in terms of external inputs but a higher input of farmers’ labor. The price premium received by farmers for the organic tea compensated for the extra labor input and lower yield, resulting in a net profit. However, given the relatively small plots of tea gardens of each household, organic production could not fully provide for the households’ livelihood. Non-farm income dominated the total income of the households across the study cases, despite the earnings from organic farming. In both sites, market-oriented organic tea projects have created more options for paid work locally, which benefits women of reproductive age. Social benefits of organic farming were also reported. Pursuing fair trade certification on top of organic production facilitated farmer organizing, training and community development. Organic agriculture and fair trade certification offer important prospects to improve the livelihoods of small-scale farmers in other, less favored areas of Asia. These forms of certified production could provide economic and social benefits in instances where farm income is the main source of household income.
Growing global trade with organic products has increased the demand for environmental impact assessments during both production and transport. Environmental hotspots of organic soybeans produced in ...China and imported to Denmark were identified in a case study using a life cycle assessment approach. Furthermore, environmental impacts of organic and conventional soybeans at farm gate were compared in the case study. The total global warming potential (GWP) per ton organic soybeans imported to Denmark revealed that 51% came from transportation and 35% from the farm level. Comparing organic and conventional soybean at farm gate showed that GWP, non-renewable energy use, acidification and eutrophication was lower per ton organic soybeans, whereas land use was slightly higher.
This book provides a timely analysis and assessment of the potential of organic agriculture (OA) for rural development and the improvement of livelihoods. It focuses on smallholders in developing ...countries and in countries of economic transition, but there is also coverage of and comparisons with developed countries. It covers market-oriented approaches and challenges for OA as part of high value chains and as an agro-ecologically based development for improving food security. It demonstrates the often unrecognised roles that organic farming can play in climate change, food security and sovereignty, carbon sequestration, cost internalisations, ecosystems services, human health and the restoration of degraded landscapes. The chapters specifically provide readers with:
an overview of the state of research on OA from socio-economic, environmental and agro-ecological perspectives
an analysis of the current and potential role of OA in improving livelihoods of farmers, in sustainable value chain development, and in implementation of agro-ecological methods
proposed strategies for exploiting and improving the potential of OA and overcoming the constraints for further development
a review of the strengths and weaknesses of OA in a sustainable development context
The potential contribution of organic farming to the public goods, ‘Nature and Biodiversity’, ‘Environment’, ‘Energy and Climate’, ‘Human Health and Welfare’ and ‘Animal Health and Welfare’ in ...Denmark is guided and partly secured by the principles and specific requirements of the EU Organic Regulation. However, other factors, such as the production type, farm size, geographical location and—not the least—the management of the farm, also influence the contribution. Using the ban on synthetic pesticides and restricted use of antibiotics, including the requirements to compensate for and prevent such uses in organic farming, as examples, the positive and negative contributions of organic farming in relation to selected public goods were analysed. The contributions of organic farming to Nature and Biodiversity and Human and Animal Health and Welfare are mainly positive compared to conventional farming for all farm types, whilst the effects on Environment and Energy and Climate are mixed; i.e. some effects are positive and others are negative. The analysis revealed a need for further documentation and revision of the organic principles and specific organic requirements—in particular in relation to the public goods Energy and Climate, which at present are not addressed in the EU Organic Regulation. Moreover, some organic farming requirements and practices cause dilemmas; e.g. more space per animal and outdoor access improves Animal Health and Welfare but at the same time has negative effects on Environment, Energy Consumption and Climate Change. These dilemmas should be solved before OA may be fully attractive as an integrated policy measure supporting jointly several public goods objectives.
There is an increased understanding that the challenges of producing enough food and biomass while preserving soil, water and biodiversity necessary for ecosystem services can not be solved by ...prevalent types of conventional agriculture and that agro-ecological approaches and ecological intensification is fundamental for our future food production. FAO has stated that “Ecosystem services sustain agricultural productivity and resilience” and advocates production intensification through ecosystem management. Terminologies such as agro-ecology and ecological/ eco-functional/sustainable intensification are being proposed for agricultural development, which builds on higher input of knowledge, observation skills and management and improved use of agro-ecological methods. Contrary, increased global demand for food, and non-food biomass has increased the pressure for intensifying land use and increasing crop yields based on conventional inputs, while still aiming at reducing environmental impact. There is a battle of discourse between these approaches in competition for – among others – research and development funding. The examples of improved local food security from introducing agro-ecological and low external input agriculture practices among smallholder farmers are many. However, upscaling remains a challenge and the ability of such eco-functional intensification to feed the increased urban populations in emerging economies remains an open question. A broader view of what is organic and conventional farming is necessary and the use of new understandings from ecology and molecular biology will be needed to create and profit from synergies between preserving and building on eco-systems services and providing increased food and biomass.
In the quest for sustainable intensification of crop production, we discuss the option of extending the root depth of crops to increase the volume of soil exploited by their root systems. We discuss ...the evidence that deeper rooting can be obtained by appropriate choice of crop species, by plant breeding, or crop management and its potential contributions to production and sustainable development goals. Many studies highlight the potentials of deeper rooting, but we evaluate its contributions to sustainable intensification of crop production, the causes of the limited research into deep rooting of crops, and the research priorities to fill the knowledge gaps.
Recent studies have documented highly significant differences among current and potential crops, as well as genotypic differences, in the ability for deep rooting.Results have shown significant effects of deep roots on deep soil water and nutrient uptake.Technological improvements of nondestructive methods, such as rhizotron and image analysis based root observations, soil water sensors, and isotope tracers for uptake studies, allow combined and dynamic studies of root development and function.The quest for sustainable intensification of crop production promotes the interest in understanding and exploiting the potential contribution by deeper soil layers. Deep layers may contribute to resource supply for crop growth, reducing losses to the environment and deep C sequestration to mitigate climate change.
Organic agriculture can sustain rural development and ease poverty. However, whether it could be a viable pathway to improve the livelihoods of small-scale farmers in the context of urbanisation and ...demographic change has been less studied. To understand this, household surveys were conducted in 2007 and 2014 in Wanzai, Jiangxi Province China, where organic farming started in 2000. The results show that organic farming did contribute to higher farm incomes for small-scale farmers (<1ha land) compared to those practicing conventional agriculture, regardless of whether the profitability is measured on a per land unit or per household basis. The annual farmers household net income increased from 2007 to 2014, however, the farm income of small-scale farmers only makes up a minor part of total household income and its percentage becomes less and less over time. For medium-scale organic farmers (>1ha land), the proportion of income from farming was higher (56% in 2007 and 77% in 2014), leading to average farm incomes of USD16,108 in 2014. Among organic farmers, cooperatives members performed better economically than those not in cooperatives. Organic agriculture can ensure stable and sustainable alternative livelihoods, especially in a situation where available land offers opportunities for scaling up.
•Organic farming could provide higher farm income to small-scale farmers (<1 ha land) compared to conventional agriculture.•Organic agriculture impact for livelihood improvement depends on their available total organic arable land.•The farm income for organic medium sized farmers (>1 ha land) was 2 times more of the national average household income.•Organic agriculture could be an alternative livelihood strategy from the socio-economic perspective.•Farmers in cooperatives performed better in economic terms than those not in cooperatives.
