Assessing rice production sustainability performance indicators and their gaps in twelve sub-Saharan African countries

The benchmarking and monitoring of rice production performance indicators are essential for improving rice production self-sufficiency, increasing profitability, reducing labor requirements, optimizing fertilizer inputs, engaging youths in rice production, and increasing the overall sustainability of smallholder rice production systems in countries in sub-Saharan Africa (SSA). In this paper, we quantified five sustainability performance indicators (grain yield, net profit, labor productivity, and nitrogen (N) and phosphorus (P) use efficiencies) to benchmark rice production systems in SSA. Data were collected between 2013–2014 from 2907 farmers from two rice production systems (irrigated and rainfed lowlands) across five agroecological zones (arid, semiarid, humid, subhumid and highlands) in 12 countries (Benin, Cameroon, Cote d’Ivoire, Ghana, Madagascar, Mali, Niger, Nigeria, Senegal, Sierra Leone, Tanzania and Togo). The exploitable gap for each indicator (the difference between the mean of 10 % highest-yielding farms and the mean-yielding farms) was calculated across the countries, the two production systems and agroecological zones. The mean yield varied widely between 2.5 to 5.6 t ha−1 and 0.6 to 2.3 t ha−1 in irrigated and rainfed lowlands, respectively, with an average yield of 4.1 and 1.4 t ha−1, respectively. Across the country-production system combinations, there were yield gaps of 29–69 %, profit gaps of 10–89 %, and labor productivity gaps reaching 71 %. Yield, profit, and labor productivity were positively correlated. They were also positively correlated with N and P fertilizer application rate, but not with N and P use efficiencies. Only between 34–44 % of farmers had desirable ranges in N- or P-use efficiencies in the two production systems. All sites for rainfed lowlands were characterized by low-yield and large gaps in yield, profit, and labor productivity, whereas irrigated lowlands in some countries (Madagascar, Mali, and Togo) have similar characteristics as rainfed ones. We conclude that there is an urgent need to disseminate precision nutrient management practices for optimizing nutrient use efficiency and enhancing rice performance indicators especially in rainfed lowlands as well as low-yielding irrigated lowlands. Furthermore, we propose recommendations for specific categories (i.e. farmer, rice production system, agroecological zone and country) to close performance indicator gaps and to allow the production at scale to achieve rice self-sufficiency in SSA

Accessing health services in India: Experiences of seasonal migrants returning to Nepal.

Background: Migration to India is a common livelihood strategy for poor people in remote Western Nepal. To date, little research has explored the degree and nature of healthcare access among Nepali migrant workers in India. This study explores the experiences of returnee Nepali migrants with regard to accessing healthcare and the perspectives of stakeholders in the government, support organizations, and health providers working with migrant workers in India. Methods: Six focus group discussions (FGDs) and 12 in-depth interviews with returnee migrants were conducted by trained moderators in six districts in Western Nepal in late 2017. A further 12 stakeholders working in the health and education sector were also interviewed. With the consent of the participants, FGDs and interviews were audio-recorded. They were then transcribed and translated into English and the data were analysed thematically. Results: The interviewed returnee migrants worked in 15 of India’s 29 states, most as daily-wage labourers. Most were from among the lowest castes so called-Dalits. Most migrants had had difficulty accessing healthcare services in India. The major barriers to access were the lack of insurance, low wages, not having an Indian identification card tied to individual biometrics so called: Aadhaar card. Other barriers were unsupportive employers, discrimination at healthcare facilities and limited information about the locations of healthcare services. Conclusions: Nepali migrants experience difficulties in accessing healthcare in India. Partnerships between the Nepali and Indian governments, migrant support organizations and relevant stakeholders such as healthcare providers, government agencies and employers should be strengthened so that this vulnerable population can access the healthcare they are entitled to

Microbial biotransformation of beclomethasone dipropionate by Aspergillus niger

In the present research, the steroidal anti-asthmatic drug beclomethasone dipropionate was subjected to microbial biotransformation by Aspergillus niger. Beclomethasone dipropionate was transformed into various metabolites first time from microbial transformation. New drug metabolites produced can act as new potential drug molecules and can replace the old drugs in terms of safety, efficacy, and least resistance. They were purified by preparative thin layer chromatography technique, and their structures were elucidated using modern spectroscopic techniques, such as 13C NMR, 1H NMR, HMQC, HMQC, COSY, and NOESY, and mass spectrometry, such as EI-MS. Four metabolites were purified: (i) beclomethasone 17-monopropionate, (ii) beclomethasone 21-monopropionate, (iii) beclomethasone, and (iv) 9beta,11beta-epoxy-17,21-dihydroxy-16beta-methylpregna-1,4-diene-3,20-dione 21-propionate
