A group of researchers and industry writers have constructed a narrative of technological triumph for Bt cotton in India, based on an empirical record of superior performance compared to conventional seed. Counterclaims of Bt cotton failure are attributed to mutually reinforcing interactions among non-governmental organisations which avoid rigorous comparisons. However, researchers and the biotechnology industry are also engaged in a similar authentication loop for generating, validating, and publicising such facts.
This article rebuts the argument that shortcomings in Bt cotton studies and divergence between yield gains and extent of adoption of Bt hybrids make it impossible to conclusively say anything about the impact of genetically modified seeds. Further, it points out that there have been numerous studies that have controlled for selection and cultivation bias, and concluded that Bt cotton has had statistically significant positive yield effects.
Genetically engineered (GE) foods apply new molecular technologies to Widely adopted in the United States, Brazil, and Argentina for the p corn, soybeans, and cotton, they are practically banned in Europe and tigh throughout the world. We have found that GE foods have significantly incr of corn, soybean, and cotton, and lowered their prices, thus improving food foods have already contributed to a reduction in the use of pesticides and
La investigación participativa ecológica forestal y agroforestal (IPEFA) se concibe y se practica de muy distintas maneras, definidas por voluntad de quienes investigan y/o por las circunstancias que enfrentan.
The Government of Pakistan has adopted a policy of providing agricultural extension services to promote agricultural production by disseminating appropriate knowledge and technologies to farmers. Consistent with this national policy, farmers in Balochistan have been provided with extension services by the provincial Department of Agriculture through their extension officials working with the District of Agricultural Extension Department.
This review paper is based on secondary information. It presents the external (policy, technical assistance, public institutions and the private sector) and internal (institutional structures, objectives/programmes) factors that impact on agriculture development in general in developing countries with special focus on Pakistan. The contents carry the literatures that deal with such factors, starting with discussion on the comprehensive analysis of the role of extension services accompanied by its pros and cons, as well as the meager agricultural services in developing countries.
This study is designed to assess the factors that affect smallholder rice farmer’s participation in market. In addition it also examines the effect of commercialization on the welfare of smallholder farmers. The method of Heckman two-stage model is used to obtain the desired objectives. Random sampling technique is used to collect data from 249 smallholder farmers.
In the past 15 years, Tanzania has made considerable progress in the fight against child undernutrition. This paper analyses in what respects an enabling environment for nutrition action in Tanzania has emerged. It critically investigates the nature of government political commitment and assesses the breadth and depth of a range of public policies, initiatives and actions within and across nutrition-specific and nutrition-sensitive sectors, and at the national, sub-national and community levels.
Given the increasing tension between food production and food demand in sub-Saharan Africa, as well as the poor development of the rice sector in Africa, the present paper examines the impact of agricultural extension on adoption of chemical fertilizers and their impact on rice productivity in Ghana. A parametric approach was employed to account for selectivity and endogeneity effects, which most impact studies fail to address. The empirical results reveal that agricultural extension service is endogenous in the chemical fertilizer adoption specification
In Vietnam, while glutinous rice farming represents a very small sub-sector of rice production, it plays an important role in the food and cultural security of farming households in many remote areas. This paper examined glutinous rice farming in households, as a food and for cultural security, and the extension services in areas producing glutinous rice. Data were collected from 400 local farmers based on interview schedules and statistical analysis using the percentage, arithmetic mean, and hypothesis testing with logistic regression
