Local seed systems and village-level determinants of millet crop diversity in marginal environments of India:

"In the subsistence-oriented, semi-arid production systems of Andhra Pradesh and Karnataka, India, the environment is marginal for crop growth and often there is no substitute for millet crops. Across communities, farmers grow thirteen different combinations of pearl millet, sorghum, finger millet, little millet, and foxtail millet varieties, but individual farmers grow an average of only two to three millet varieties per season. The notion of the seed system includes all channels through which farmers acquire genetic materials, outside or in interaction with the commercial seed industry. Data are compiled through household surveys and interviews with traders and dealers in village and district markets. Based on the concept of the seed lot, several characteristics of local seed markets are defined and measured by millet crop, including seed transfer rates for farmer-to-farmer transactions and seed replacement ratios. Most seed transactions appear to be based on money. Seed supply channels differ by improvement status of the genetic material. Econometric results indicate the significance of the seed replacement ratios and seed volumes traded in determining the levels of crop biodiversity managed by communities, in addition to the household, farm and other market-related factors identified by previous studies. These are interpreted as indicators of market strength." Authors' AbstractSeed systems, Crop diversity, Seed industry and trade, genetic variation,

Comparing farm and village-level determinants of millet diversity in marginal environments of India: the context of seed systems

"The purpose of the research paper is to characterize biological diversity related to millets in the semi-arid regions of India at various spatial scales of analysis (e.g., farm household versus community levels) and place that evidence in a broader seed systems (includes both formal and informal) context. An important finding of this research is that producer access to millet genetic resources is affected by the extent to which seed is traded via formal markets or through other social institutions, along with farm and household characteristics. Findings also underscore the need for an enhanced theoretical understanding of local seed markets in analyzing crop variety choices and the diversity of materials grown in less favored environments."

Supply of pigeonpea genetic resources in local markets of Eastern Kenya:

"Smallholder producers in marginal and semiarid areas of eastern Kenya have not benefited greatly from research investments made in improvement of crops grown in such environments (sorghum, millet, and legumes, including pigeonpea) either by the international community or the national agricultural research system because of poorly developed seed systems. However, informal and local market purchases are the major sources of seed for non-maize cereals and legumes. In the absence of any formalized seed system for dryland crops, more and more farmers rely on local markets to supply seed during normal and disaster periods. We determined the factors affecting the quantities of pigeonpea traded by vendors during the 2006 short-rains season using simple OLS estimation. We found that the participation of traders and farmers was higher and traded larger quantities of pigeonpea in weekly markets located in areas where seed-based intervention programs in place than in non-intervention areas. Also agro-ecologically, markets located in slightly wetter regions offered more varieties and handled higher sales compared with marketsheds in dry regions. Among the traders, the grain traders dominated through their sheer volume of sales, higher investment, and storage capacity in these markets though the distinction between seeds and grains was poor. Of the vendor characteristics, young, educated vendors traded higher quantities of pigeonpea during the planting season. The amount of time spent selling by different vendors in the village fairs also had a significant influence on the pigeonpea quantity traded. Certain market infrastructure variables such as distance to the local markets and the access to information sources (mobile phones) also significantly influenced the amount of pigeonpea sold among vendors in these markets. The existing pigeonpea value chain in local markets could be improved further, provided proper synergies exist between different actors in the system. This would enhance local crop diversity levels as well as improve access to quality plant materials for farming communities in the marginal environments of eastern Kenya." from authors' abstractLocal markets, village markets, Seed systems, Drylands, legumes,

ECONOMIC IMPACTS OF INTERNATIONAL AGRICULTURAL RESEARCH: CASE OF US-EGYPT-IRRI COLLABORATIVE PROJECT ON THE GENERATION OF NEW RICE TECHNOLOGIES

Agricultural research managers and scientists are under increasing pressure to demonstrate the efficient and socially-effective use of funds spent on agricultural R&D. These pressures stem from heightened expectations of transparency and accountability in the use of public funds, as well as from the growing demand for evidence of impact on target social groups and environmental services. Finally, advances in agricultural biotechnology research and the ensuing dialogue about the desirability of using biotechnology tools for increasing food production in developing countries have highlighted the need to assess the impacts of international agricultural research in the US, the developing countries, and the international agricultural research centers (IARCs). The US-Egypt ATUT project, funding involves collaborative research among plant breeders, molecular geneticists, and other agricultural scientists in the US, Egypt and IRRI. ATUT rice research accelerated the utilization of three methods for improving the speed and reliability of the screening and evaluation process for identifying salt resistant varieties: shuttle breeding, anther culture and marker-assisted selection. ATUT initiated the application of Marker Assisted Selection (MAS) technology for screening Egyptian rice germplasm. Other ATUT rice technologies in the pipeline have various levels of AATUTness in their research and development. Some of the varieties to be released starting 2003 such as short duration HYVs, will have benefitted less directly from ATUT funding and scientific collaboration. Others- such as hybrid rice varieties will have been very significantly shaped by ATUT. The DREAM model under IFPRI's Global and Regional Program on Agricultural Science and Technology Policy, is used to assess the potential economic benefit of technology outputs for rice, under a range of likely adoption, market and trade scenarios. The simulation model, based on economic surplus theory, uses data and parameters from interviews with scientists, policy makers on the impact and adoption of technology. For this study, ex-ante simulations of the most likely range of outcomes with and without the innovations from ATUT investments. Analyzing the impact of technical change (a simulation over a specified number of years) has provided year-by year estimates of changes in: prices, quantities produced, consumed and traded, levels of adoption, economic benefits to consumers, economic benefits to adopters or losses (non-adopters) to producers. For US and IRRI benefits: Enhanced germplasm pool, stock of knowledge and facilities, and better informed scientists. US scientists in California and Arkansas benefit More integrated into the international rice research community. Gross benefits are estimated for governorates, by producers and consumers, by saline and normal soils, for 1997 to 2017 (end of GoE's current strategic horizon) discounted to 1997 US$. Producers in normal soils derive higher benefits than those in saline soils, some governorates reap more of the producer benefits than others; rural consumers benefit more than urban consumers. Consumer benefits are also estimated for importers of Egyptian rice such as Turkey, Sudan and aggregated Arabian countries. Cost of rice R&D and technology transfer will be measured to derive the IRR and B/C ratios.Research and Development/Tech Change/Emerging Technologies,

Seed provision and dryland crops in the semiarid regions of Eastern Kenya:

"Over the last two decades, several seed-related programs have been initiated in eastern Kenya to improve farmers' access to quality seeds of dryland cereals and legumes. They are provided during two occasions, regular and emergency times. But very often, the formal supply mechanisms limit their role in provision of seeds other than maize. In the absence of any formalized systems of seed provision for other dryland crops, such as sorghum and pigeon pea, farmers have preferred local markets for their seed needs, especially during distress periods. Here we have examined the role of various seed-intervention programs in eastern Kenya, along with the strengths and weaknesses of each program. We have also underscored the importance of local markets and their actors in meeting the needs for non-maize and bean seeds in these marginal environments. For this purpose, detailed, informal interviews were conducted during October–December 2005 with all the stakeholders, namely public and private institutions and vendors in eight major local markets in eastern Kenya. The results of the study call for synergies between existing formal (private, public, and other development initiative) systems and informal (local market) seed systems to enhance crop yields and the diversity of dryland cereals and legumes through effective seed-supply interventions." from Author's AbstractSeed interventions, Local markets, Seed systems, Dry lands, Seed access, Eastern Kenya,

Collective action and marketing of underutilized plant species: The case of minor millets in Kolli Hills, Tamil Nadu, India

"Minor millets are examples of underutilized plant species, being locally important but rarely traded internationally with an unexploited economic potential. In the Kolli hills of Tamil Nadu, India, a genetically diverse pool of minor millet varieties are grown by the tribal farming communities to meet their subsistence food needs. Most of these minor crops were not traded outside the farming community. Despite a consumption preference among the farming communities for minor millets, in the recent past the acreage under minor millet crops have declined considerably due to the availability of substitute cash crops. As a response, the M.S. Swaminathan Research Foundation (MSSRF) based in Chennai has led targeted conservation cum commercialization intervention programs over the last 7-9 years in the Kolli Hills. In this paper we provide a first evaluation of the success of marketing development for minor millets in the Kolli Hills with a specific focus on collective action and group initiatives undertaken by the women and men self-help groups organized by the concerned non-governmental organization. We analyze the key collective actions that are taking place in the minor millet marketing chain through a series of field visits and focus group discussions with the stakeholders involved. We then compare the role of collective action in this new market with the case of marketing chains for cassava and organic pineapples, two cash crops with an expanding production in Kolli Hills. Our analysis shows the critical role of collective action and group initiative as a necessary but not sufficient condition for the successful commercialization of underutilized plant species for the benefit of the poor and the conservation of agrobiodiversity." authors' abstractCollective action, Underutilized species, Agricultural marketing, Agrobiodiversity, Markets, Small farmers,

Mycological Profile in Otomycosis Patients and their Drug Sensitivity: A Cross-sectional Study at Union Territory of Puducherry, India

Introduction: In clinical Otorhinolaryngology practice, otomycosis is a common problem to overcome caused by Aspergillus and Candida species. Although, we come across many difficulties to diagnose and treat otomycosis infections, many patients show drug resistance to antifungal agents with a high prevalence rate. Aim: To elucidate the pattern of mycological agents and susceptibility testing of fungal species in samples collected from patients with an ear infection at a tertiary hospital. Materials and Methods: The present hospital-based crosssectional study conducted in the Department of Microbiology and Department of Ear, Nose, and Throat (ENT) at Aarupadai Veedu Medical College and Hospital, Puducherry, India, from August 2018 to January 2020. A total of 126 samples were collected, transported and analysed for bacteriological and mycological analysis using direct inspection and culture techniques. By using the disc diffusion technique, the antifungal susceptibility testing was carried out to determine the sensitivity and resistance against ketoconazole, itraconazole, fluconazole, and amphotericin B. Data were analysed in terms of frequency using the Statistical Package for the Social Sciences (SPSS) software 25.0 version. Results: Out of 126 samples, fungal isolates were 92, out of which the most common fungal isolate was Aspergillus niger followed by A. flavus, Candida albicans (C. albicans), A. terreus, and A. fumigatus. Also, the major common bacterial isolates were Staphylococcus aureus followed by Pseudomonas, Proteus, Escherichia coli (E. coli), and Klebsiella spp. Prevalence in males (58.73%) was more as compared to the females (41.27%), and itching was the most common presenting symptom. Otomycosis in Chronic Suppurative Otitis Media (CSOM) mainly affected males (40%) and is common in middle-aged groups (20-35 years) of outdoor and indoor workers, housewives and farmers, particularly during the monsoon season. Antifungal susceptibility testing of A. flavus and A. niger isolates revealed high sensitivity to amphotericin B, itraconazole and ketoconazole drugs but low efficacy to fluconazole drugs. Conclusion: Otomycosis should be suspected clinically to prevent the unnecessary use of antibiotics. A high incidence of otomycosis has been encountered in many tropical countries. In present study, Aspergillus spp. and Candida spp. were the commonest fungal isolates in otomycosis. In our community, currently two drugs, amphotericin B and ketoconazole are the most frequently used for fungal infection. Properly identifying fungal agents and host factors involved in otomycosis can improve such patients’ outcome
