- Impact of direct rice-sowing technology on rice producers' earnings: empirical evidence from Pakistan(Taylor & Francis, 2014) Ali, A.; Erenstein, O.; Rahut, D.B.Using the comprehensive data set collected from 238 rice producers during 2011, this study estimates the impact of direct seeding of rice-sowing technology on rice and wheat crop yields and farmers' earnings in Pakistan. The propensity score-matching approach was employed to correct for potential sample selection bias that may arise due to systematic differences between the adopters and non-adopters of the direct rice-sowing technology. The empirical results indicate that the adopters of the direct rice-sowing technology have higher rice and wheat crop yields as compared to non-adopters. The rice yields are high, in the range of 8–9 maunds per acre, while the wheat yields are higher, in the range of 2–3 maunds per acre, indicating that the direct rice-sowing technology also has a positive impact on the following wheat crop. Results show that the adopter households have a higher income compared to non-adopter households. Most importantly, the new technology is a water-saving technology and on average it requires four times less irrigation than the traditional rice transplanting method. With the direct rice-sowing technology, the demand for skilled labor was less compared to the traditional transplanting method. However, the new technology is associated with a weed control problem, which needs to be addressed in order to maximize the benefits from the new technology.
Publication - Assessing farmer use of climate change adaptation practices and impacts on food security and poverty in Pakistan(Elsevier, 2017) Ali, A.; Erenstein, O.Climate change is set to be particularly disruptive in poor agricultural communities. We assess the factors influencing farmers’ choice of climate change adaptation practices and associated impacts on household food security and poverty in Pakistan using comprehensive data from 950 farmers from its major provinces. A probit model was used to investigate the factors influencing the use of climate-change adaptation practices; the censored least absolute deviation (CLAD) was used to analyze the determinants of the number of adaptation practices used; and a propensity score matching (PSM) approach was employed to evaluate the impact of adaptation practices on food security and poverty levels. Adjustment in sowing time (22% households), use of drought tolerant varieties (15%) and shifting to new crops (25%) were the three major adaptation practices used by farmers in the study area. Results show that younger farmers and farmers with higher levels of education are more likely to use these adaptation practices, as do farmers that are wealthier, farm more land and have joint families. The number of adaptation practices used was found to be positively associated with education, male household heads, land size, household size, extension services, access to credit and wealth. Farmers adopting more adaptation practices had higher food security levels (8–13%) than those who did not, and experienced lower levels of poverty (3–6%). Climate change adaptation practices at farm level can thereby have significant development outcomes in addition to reducing exposure to weather risks.
Publication - Impact of zero tillage adoption on household welfare in Pakistan(Association of Agricultural Technology in Southeast Asia (AATSEA), 2013) Ali, A.; Erenstein, O.The current study was carried out to estimate the impact of zero tillage technology adoption on household welfare in Pakistan. For the study cross sectional data set was collected from 234 households in the rice-wheat area of Pakistani Punjab. The data was collected through stratified random sampling technique from 3 main districts of rice-wheat area namely Gujranwala, Sheikhupura and Hafizabad. The empirical analysis was carried out by employing the propensity score matching approach to correct for potential sample selection biased ness that may arise due to systematic differences between adopters and non adopters. The empirical result indicates that adoption of zero tillage technology has positive and significant impact on wheat yield and household income while non significant impact on rice yield. Most importantly the adoption of zero tillage technology can help to reduce poverty among rural households in the range of 8-10 percent.
Publication - Impact of agricultural extension services on technology adoption and crops yield: empirical evidence from Pakistan(Asian Economic and Social Society, 2013) Ali, A.; Rahut, D.B.The present study was carried out in the rice-wheat area of Pakistani Punjab. The data for the study was collected from three main districts of central Punjab Province i.e. Gujranwala, Sheikhupura and Hafizabad. In total 234 farmers were interviewed. The impact of agricultural extension services was estimated on adoption of new improved technologies and crop yields. The propensity score matching approach for impact evaluation was employed in the current study to correct for potential sample selection biasedness that may arise due to systematic differences between the farmers having benefited from agricultural extension services and not benefited from agricultural extension services. The empirical results indicate that agricultural extension services play a significant role in adoption of improved agricultural technologies like laser leveling, rice and wheat varieties. The farmers having benefitted from agricultural extension services were also getting higher rice and wheat yields. The results also indicates that mostly the large farmers are getting benefits from agricultural extension services and small scale farmers have less access to agricultural extension services.
