Determinants of adoption of wet-and dry-season improved rice varieties in Cambodia were analyzed.... more Determinants of adoption of wet-and dry-season improved rice varieties in Cambodia were analyzed. Selection pattern and intensity of information sources, and barriers to adopt agricultural technologies by rice farmers were examined. Probit model was used to analyze household survey data, covering 24 provinces, 48 districts, 95 communes and 192 villages. The results show that farmers use a combination of information sources to meet their needs indicating that any single source does not satisfy all the farmers' information needs. The most used information sources were farm radio and television, followed by farm extension meetings/workshops. Frequent service providers for both male and female farmers were NGOs, local commune/village office and local extension service centers. The frequently-mentioned barriers to adopting new farm technologies are lack of technical knowledge/skills and technological incompatibility-farmers stated that technologies were not suitable to their farms. This may mean either that the technology is not climatically fit or it is labor-intensive, costly or not suitable to smallholder farmers. Other frequently mentioned barriers were unavailability of credit to invest in new technology and access to market information. Adopters and non-adopters were significantly different in educational levels, access to improved seeds, and contact with extension agents. The study highlights how the farmer's age, educational level, family size, and extension-related variables influenced the farmer's behavior in selecting wet-and dry-season rice varieties. Use of seed from their own harvest showed a negative effect on adoption, suggesting that access to seed from reliable sources will benefit the farmers by increasing production and income. Incorporating researchers' and extension officials' message in television and radio programs, and implementing educational learning programs may be the policy alternatives to enhance adoption and rice productivity in Cambodia.

However, much less studies have been devoted to the factors that influence nonfarm income diversification by farm household in developing countries. Using cross-sectional data and a probit model, this study attempts to determine the factors influencing nonfarm income diversification decisions by farm households in Central Nepal. The result reveals that household characteristics such as age, gender and education of the household head, and family size play a significant role in nonfarm work decisions. The households with larger farm size are less likely to participate in nonfarm work than their counterpart. Additionally, for those remains in the rural households, distance to road and market hinders the opportunities for nonfarm work. Finally, regional differences also exist in participating nonfarm activities among farm households. This study...

This study intended to analyze the market price cointegration of tomato and its effect on Nepalese farmers, using secondary monthly time series of wholesale price data (since 2000 to 2010) of the Government of Nepal. The results of error correction model (ECM) showed that the series were stationary, and Kathmandu market was well cointegrated with source markets (Chitwan and Morang). Meanwhile, the vector error correction model (VECM) revealed that price adjustment process was much faster in source markets especially in negative price shocks in response to Kathmandu market, which affected the farmers for speedy price adjustment that leads to be hurt and discouraged. The study recommend policies to establish alternative vegetable markets that reduce the price dependency of farmers on Kathmandu market, encourage traders in involving vegetable marketing, and enhance effective market information services.
Increasing agricultural production and reducing poverty through a modernized agricultural system ... more Increasing agricultural production and reducing poverty through a modernized agricultural system has been a priority of the government of Ghana. We analyzed the trends of major crop yields, cultivated area, and fertilizer input in two villages – Tongoli and Gbullung – of Tolon-Kumbung district in northern Ghana. Using longitudinal panel data from 67 households from 2004 to 2015, we performed statistical analyses such as percentage, average, frequency, and trend analysis, and used time fixed effect regression model to determine the relationship between the value of crop production and independent variables such as labor, input cost, area, income, and occupation. The results show that total cultivated area continues to decrease as family size and the number of farmers per compound decrease. The number of cultivated crops decreased, and the yield of major crops became unstable. However, the number of farmers aiming to increase production by using chemical fertilizer on maize and rice i...

The study aimed to measure and to analyze the production efficiency of smallholder vegetable farms in eastern hill, Nepal, using Nepal vegetable crops survey (2010) data of the Central Bureau of Statistics, Government of Nepal. The results of maximum likelihood estimates of Stochastic Frontier Analysis revealed that the mean technical efficiency score was 0.77, implied that 23 percent production could increase by simply improving vegetable farming practices. The production was contributed by land, labor, seed, compost, fertilizer, pesticide, farm capital, seed types, credit, technical support and sex of household head. Therefore, this study recommend policies on improvement of land, develop skillful labor, promote improve seed, encourage composting, easily access of fertilizer, pesticide and farm capitals, promoting women farmer, enh...

This study investigated the key factors associated with improved maize varieties (IMVs) adoption and intensity of adoption by farm households in Central Nepal. A multistage random sampling technique was used to select a sample of 416 farm households and interviewed by using structured survey questionnaires. We used Cragg's double-hurdle model to analyze the data. The results showed that education appeared to be positively influencing the adoption decisions while age of the household head had the negative influence on adoption decision. Additionally, farm size and livestock asset showed significant positive effect on adoption of IMVs. After the adoption, varietal characteristics such as yield potential and pest/disease resistance significantly affected the adoption intensity. Developing mechanisms to help promote IMVs adoption and its intensity by varietal specific characteristics for example yield, pest/disease resistance, palatability and storability is therefore a reasonable policy instrument to increase the adoption rate and use intensity. However,a comprehensive package that includes effective extension services and efficient input distribution system is certainly a requirement for increasing production and ensuring food security in rural areas.

The objective of this study was to examine the rice yield distributions, estimate yield risks at country level, and compare risks between five countries namely Afghanistan, Bangladesh, Nepal, Sri Lanka, and Pakistan. Anderson Darling (AD) test was applied to test the goodness-of-fit for four distributions by using country level de-trended rice yields from 1961 to 2010. Results showed the Normal distribution was fitted well in Afghanistan and Sri Lanka, whereas the Weibull distribution in Bangladesh, Nepal, and Pakistan. The average yield risks at 85% of the expected yield were found 5.29, 4.27, 3.86, 1.55, and .15% in Afghanistan, Sri Lanka, Pakistan, Nepal, and Bangladesh, respectively. Wilcoxon signed rank test results of mean absolute percentage differences showed yield risk in Bangladesh was significantly lower than the rest four counties and t...

However, it is unclear how rural and smallholder farmers can best learn about, adopt, and benefit from technological advances. Extension services with multiple linkages to organizations and farmers have been identified as a positive factor in successful adoption of new technologies. Participatory action research was undertaken in Kaski district of Nepal focused on introducing new (for the local context) technologies for off-season vegetable. The project sought to demonstrate best practices in agricultural extension and showcase a demand-driven, participatory, and pluralistic model of agricultural extension. It was hypothesized that doing so would enhance the productivity, income, and food security of participating rural households. Two household surveys were conducted-a baseline survey in 2013 (before the project) and endline survey in 2015 (after the project)-to collect data and study the impact of the intervention, if any, on household wellbeing. The results show the participatory approaches used to be associated with enhanced productivity, income, and food security for participant households. The results show that the area under off-season vegetable production, marketed vegetable volume, and income increased significantly. It appears that vegetable production and income tripled while the area of land dedicated to off-season vegetable production doubled at the end of the project. The types of crops grown by participant households also significantly increased over the project period. Furthermore, participant farmers were found to organize into groups for knowledge sharing, adopting new technology, and increasing household income. The results suggest that phase-wise learning and scaling up approach used in the off-season vegetable production can be replicated to disseminate new technologies in other contexts to strengthen extension service delivery.

HARVEST program interventions focused on increasing incomes to influence nutrition outcomes. This was achieved through an approach that integrated activities from a range of sectors —agriculture, fisheries, forestry, nutrition and more —to help families in rural areas grow, p urchase, and prepare more nutritious foods. Cambodia HARVEST was rolled out in phases over the 5 1/2-year period, which ended in June 2016. Over that time, the project’s strategy evolved as activities were scaled up, but the overall approach remained guided by the principles of linking agriculture and nutrition to achieve some of the overarching development goals of reducing poverty and malnutrition.

Using cross-sectional farm-level data from 416 households, we first categorized households into two wealth groups – poorly endowed and well-endowed households – and then estimated Cragg's double-hurdle model for adoption and use intensity of IMVs for each group. The study found the presence of heterogeneous factors influencing adoption and intensity of adoption between poorly and well-endowed households, suggesting a need for wealth-group-specific policy interventions to increase adoption of IMVs and their subsequent impacts on food security. The results also indicated that the availability of seed in local retail outlets will benefit especially the poorly endowed farmers because distance to market showed a negative impact on adoption and intensity of adoption of IMVs. Therefore, government should establish a wide seed distribution network in rural areas, preferably by way of a public-private partnership (PPP), if the desired adoption rate and intensity of adoption are to be achieved. Linking farmers to markets by integrating farmers with potential buyers could help reduce transaction costs and make agriculture more profitable.
