The Impact

To assess the impact of commercial rice seed production on rice productivity and household income, a survey study was conducted in Gorkha, Lamjung and Tanahun districts of Nepal covering eight seed production groups. Analyses include probit regression and cost and returns from seed production. Results of the probit model showed that agricultural training, increase in household income, average age of household head, use of modern rice cultivars, household size, and involvement of women in agricultural decision making have significant positive effect on adoption of the modern rice seed production technology. Similarly, significant difference between non-adopters and adaptors was observed in relation to seed productivity. Study showed that yield of improved seed technologies are higher by 2 ton/ha than the traditional rice varieties and net income is around NRs 43,500 per hectare. Study also showed that the improved rice seed technologies, amount of seed applied, area planted, and fertilizer applied are highly significant variables affecting rice productivity.Journal of the Institute of Agriculture and Animal Science.

The Impact

Villagers’ participation in poverty alleviation programs has received considerable attention, especially with regard to the poor. However, not much is known about the welfare effect of villagers’ program participation. This paper analyzes the impact of villagers’ program participation on their incomes. We used household data from 529 villagers in China’s Whole Village Poverty Alleviation Program. We focused on two types of program participation—discussion and voting. Using the propensity score matching approach, we estimate the impact of rural households’ program participation on their income. The results show that the education and the political career of the household head determine program participation. Households participating in discussion and voting have a positive and significant effect on household income. Richer households benefit more from the program. However, the poor receive less benefits. We conclude that broadening villager’s participation can boost the effectiveness of China’s poverty alleviation program.

Abstract This paper investigates the impact of farm-nonfarm diversification (FND) on household income and food expenditure in urban Ghana using propensity score matching (PSM) technique to account for potential selection bias. We find diversified households to be statistically different from undiversified households in terms of household characteristics. Age, gender, educational attainment of the household head, household size, ownership of livestock and agricultural land, and receipt of miscellaneous and rent incomes are positive and significant determinants of FND in urban Ghana. In addition, we find that participation in both farm and nonfarm activities positively and significantly impacts household income and food expenditure. In the light of growing urbanization, with its implications for unemployment, poverty and food insecurity, we recommend diversification among urban households as a means of smoothing income and consumption.

Abstract Objectives The objective of this study is to elucidate the impact of income on short-term outcomes in a cerebellopontine angle (CPA) tumor resection population. Design This is a retrospective regression analysis. Setting This study was done at a single, multihospital, urban academic medical center. Participants Over 6 years (from June 7, 2013, to April 24, 2019), 277 consecutive CPA tumor cases were reviewed. Main Outcome Measures Outcomes studied included readmission, emergency department evaluation, unplanned return to surgery, return to surgery after index admission, and mortality. Univariate analysis was conducted among the entire population with significance set at a p-value <0.05. The population was divided into quartiles based on median household income and univariate analysis conducted between the lowest (quartile 1 [Q1]) and highest (quartile 4 [Q4]) socioeconomic quartiles, with significance set at a p-value <0.05. Stepwise regression was conducted to determine the correlations among study variables and to identify confounding factors. Results Regression analysis of 273 patients demonstrated decreased rates of unplanned reoperation (p = 0.015) and reoperation after index admission (p = 0.035) at 30 days with higher standardized income. Logistic regression between the lowest (Q1) and highest (Q4) socioeconomic quartiles demonstrated decreased unplanned reoperation (p = 0.045) and decreasing but not significant reoperation after index admission (p = 0.15) for Q4 patients. No significant difference was observed for other metrics of morbidity and mortality. Conclusion Higher socioeconomic status is associated with decreased risk of unplanned reoperation following CPA tumor resection.

ABSTRACTThis study examines farmers’ preferences for seed of new rice varieties (improved and NERICA) and their willingness to pay (WTP) for information embodied in the seed, in villages of Nigeria and Benin. Information might not generate rivalry among its users but excludability is certainly a characteristic of information and its delivery can generate incentives for private participation. Conjoint utility analysis is used to estimate the structure of farmers’ preferences for rice seed. Farmers prefer one variety based on the utility they obtain from its attributes, which depends on their own social and economic characteristics. Contingent methods are used to elicit preferences and rice seed price. The marginal values of attributes are estimated with an ordered probit regression. The WTP for seed-related information is derived from the utility model. The results have implications for the best way to finance extension services in the areas of intervention, particularly for new rice varieties.

Abstract Background Benzobicyclon (BBC) is a β-triketone herbicide (bTH) used in rice paddy fields. It has the advantages of high efficiency, low toxicity, high crop safety, and good environmental compatibility, and shows efficacy against paddy weeds resistant to other types of herbicides. However, as some important indica rice varieties are susceptible to BBC, BBC is currently only registered and applied in japonica rice cultivation areas. Results By analyzing haplotypes of the bTHs broad-spectrum resistance gene HIS1 and phenotypes for BBC in 493 major indica rice accessions in China, we identified a novel non-functional allelic variant of HIS1 in addition to the previously reported 28-bp deletion. Through detection with markers specific to the two non-functional mutations, it was clear that 25.4% of indica conventional varieties, 59.9% of fertility restorers, and 15.9% of sterile lines were susceptible to BBC. In addition, due to natural allelic variations of the HIS1 gene in the sterile and restorer lines, some two-line hybrid sterile lines were sensitive to bTHs, and the corresponding restorers were resistant. We showed the potential effectiveness of using bTHs to address the issue of two-line hybrid rice seed purity stemming from the self-crossing of sterile lines during hybrid rice seed production. Finally, allelic variations of the HIS1 gene may also play an important role in the mechanized seed production of hybrid rice. Conclusions Our findings offer guidance for the application of BBC in indica rice areas and provide a non-transgenic approach to address the seed purity issue of two-line hybrid rice.

Abstract Climate change negatively impacts rice productivity in different parts of Africa. As a matter of necessity, farmers must respond to changing the climate by choosing adaptation strategies that increase their productivities. Incidentally, studies that documented the impact of climate change adaptation actions of farmers on rice productivity are few. This study therefore analyzed the impact of climate change adaptation decisions of farmers on the profitability of rice production using cross-sectional data gathered from 240 rice farmers selected from Ebonyi State, an important rice-producing State in Nigeria, Africa's most populous country. Using descriptive statistics, multivariate probit regression, instrumental variable regression and endogenous treatment effect model, the study revealed that the common adaptation actions of rice farmers involved adoption of minimum tillage, bond and drainage, fertilizer, crop diversification, livelihood diversification, improved rice varieties, pesticide, nursery, and adjusting planting and harvesting dates. The study found several significant interactions between the choice of climate change adaptation actions and socio-economic, farm, institutional and location characteristics of rice farmers. The result further revealed that multiple adaptation decisions of farmers significantly increased returns to scale and profit of rice production. The study concludes that adaptation decisions are effective in increasing the profitability and returns to scale of rice production in the area and other regions with similar geographical, meteorological and socio-economic contexts.

The Impact

Higher-yielding rice varieties adapted to the upland conditions of Yunnan were developed and disseminated during the late 1990s. Using cross-sectional farm-level data of 448 households collected from five prefectures in Southern Yunnan, this paper carries out an econometric analysis of the determinants of variations in the adoption of improved varieties among households and assesses the impact of adoption on rice income and total household income. The two major determinants of adoption were found to be the government programs for extension of improved upland rice varieties and for terracing of sloping fields. The presence of government programs for extension and for terracing contributed to increased adoption of improved varieties. Household-specific factors such as land and labor endowments were less important as these variables had a statistically insignificant impact on adoption. The adoption of improved rice varieties increased both rice income and the average household income. About half of the household income difference observed between the full adopters and non-adopters of improved rice varieties with comparable household characteristics can be attributed directly to the adoption. The results imply that increased investments in promoting improved rice varieties and terracing will generate additional income growth in the uplands of Yunnan.

PurposeThe purpose of this paper is to estimate the impact of credit rationing on the amount of capital allocated to inputs used by rice farmers in the Mekong River Delta (MRD).Design/methodology/approachBased on the literature review, the authors propose nine hypotheses on the determinants of access of rice farmers to credit and four hypotheses on the impact of credit rationing on the amount of capital allocated to inputs used by rice farmers in the MRD. Data were collected from 1,168 farmer households randomly selected out of 10 provinces (city) in the MRD.FindingsStep 1 of propensity score matching (PSM) with probit regression shows that land value, income, education, gender of household head and geographical distance to the nearest credit institution affect the degree of credit rationing facing rice farmers. Step 2 of PSM estimator identifies that the amount of capital allocated to inputs such as fertilizer and hired labour increases when credit rationing decreases while that allocated to seed and pesticide is not influenced by credit rationing because rice farmers use these inputs adamantly regardless of effectiveness.Originality/valueThis paper sheds light on the impact of credit rationing on the amount of capital allocated to inputs used by rice farmers, which is largely different from the main focus of the extant literature just on the determinants of credit rationing facing farmers in general and rice farmers in particular.

Abstract Background Benzobicyclon (BBC) is a β-triketone herbicide (bTH) used in rice paddy fields. It has the advantages of high efficiency, low toxicity, high crop safety, and good environmental compatibility, and shows efficacy against paddy weeds resistant to other types of herbicides. However, because BBC is not safe for some important indica rice varieties, it is currently only registered and applied in japonica rice areas. Results In this study, by analyzing haplotypes of the bTHs broad-spectrum resistance gene HIS1 and phenotypes for BBC in 493 major indica rice accessions in China, we identified a novel non-functional allelic variant of HIS1 besides the previously reported 28-bp deletion. Through detection with markers specific to the two non-functional mutations, it was clear that 25.4% of indica conventional varieties, 59.9% of restorers and 15.9% of sterile lines were susceptible to BBC. In addition, due to natural allelic variations of the HIS1 gene in sterile and restorer lines, some two-line hybrid sterile lines were sensitive to bTHs, and the corresponding restorers were resistant. We showed the potential of effectively using bTHs to solve the problem of two-line hybrid rice seed purity due to self-crossing of sterile lines during hybrid rice seed production. Finally, allelic variations of the HIS1 gene may also play an important role in the mechanized seed production of hybrid rice. Conclusions Our findings provide guidance for the application of BBC in indica rice areas, and provide a non-transgenic approach to solve the problem of seed purity of two-line hybrid rice.

The Impact

This study assessed the impact of smallholders’ collaborative groupings on farm household income and their decision to adapt management strategies to mitigate the effects of climate change within their farming areas. A sample of 225 households’ farms from the participating 15 LGAs in Ondo State were randomly selected. However, only 200 questionnaires were properly filled and returned. The study deployed both descriptive and inferential statistics (t-test and regression models) to achieve its objectives. The study found that only 20% of the households have strategies to ensure a smooth succession of the management in the family farm. The results of the probit regression analysis showed that the membership of collaborative groupings significantly and positively influenced the per capita household farm income and households’ decision to adapt management strategies to mitigate the effects of climate change. In addition, findings from the study also empirically validated that farmers who adapted to the climate earned a higher farm income than non-adapters. On the strength of these findings, the study recommends that more farmers should be encouraged to form collaborative groupings where they can also share in the numerous benefits of being in such a network, including the access to more information on adaptation to climate change.
