Yet there is no consensus in the literature with respect to the factors influencing the adoption as well as the welfare outcomes of adoption. The multinomial endogenous treatment effects model adopted in the present study analyses the factors influencing the adoption and the impact of adoption in a joint framework. Results suggest that household assets, irrigation, access to information etc.

The welfare impacts of SRI adoption revealed that all combinations of SRI individually and as a group plant management, water management and soil management had an impact on yield. However, the impact of SRI adoption on household income was quite mixed. Rice is a staple food for more than half of the world's population. World rice production nearly doubled since the s to the s, mainly due to the green revolution.

A major issue with the traditional system of paddy production, particularly green revolution technology is input intensive and was also continuing cash-rich farmers.

Increasing prices of agricultural inputs prevent poor farmers from completely adopting modern production technologies. Water demand by rice farmers was also continued increasing under such circumstances, any strategy that could produce higher rice yields with less water and less expenditure is the need of the day. Under such circumstances, the system of rice intensification SRI method was suitable and followed by the farmers. The system of rice intensification is a method for increasing the productivity of rice cultivation while at the same time reducing inputs, including seeds and fertilisers, and water requirements.

The present study was conducted in Ormanjhi block of Ranchi district, to study the socio-economic profile of paddy growers, perception and constraints confronted by paddy growers under SRI method of paddy cultivation. The study revealed that the major constraints in SRI production were the lack of awareness, scarcity of skilled labour, nursery management, and drudgery in cono-weeder uses.

The major perception regarding SRI method of paddy cultivation was low demand of water, higher yield, remuneration from the government, low seed requirement, low costs of input uses. The study also discusses the importance of SRI in achieving higher rice productivity and food security. As the second largest producer and consumer, India plays an important role in the global rice economy.

Food security in India has been traditionally defined as having a sufficient supply of rice at an affordable price. However, in recent years rice cultivation in India has suffered from several interrelated problems. Increased yields achieved during the green revolution period and with the help of input-intensive methods involving high water and fertiliser use are now showing signs of stagnation and concomitant environmental problems due to salinisation and waterlogging of fields. Water resources are also limited; as such, water for irrigation must contend with increasing industrial and urban needs.

As a result of all these factors, rice farmers have experienced a downturn in productivity growth.

Since increasing the area of rice cultivation is not feasible, the additional production has to be achieved using less land, less water and fewer additional inputs. The new intensification methods for rice cultivation known as the System of Rice Intensification SRI , which originated in Madagascar, offer a promising systemic approach to enhancing rice production at affordable costs by simultaneously reducing input requirements and causing less harm to the environment.

The SRI approach is expected to enhance yield and substantially reduce water and other input requirements by altering plant, soil, water and nutrient management practices.

Suchiradipta Bhattacharjee and Dr. In the small North East Indian state of Tripura, System of Rice Intensification SRI has grown to develop into an innovation system where various stakeholders have come together to make the state self-sufficient in rice production. The lessons learnt from the SRI innovation systems in Tripura, if applied to similar crops and contexts, would definitely prove to be a model for development and prosperity. The present study was conducted in Dharwad district of Karnataka, where in some parts are coming under paddy growing area and also as it comprises more rainfall with a maximum area under paddy cultivation.

Fifteen SRI method paddy crop growers from each village were randomly selected to constitute the total sample size of Structured interview schedule was used to collect the information through personal interview. Data was analyzed by using suitable statistical tools. The major findings of the study revealed that Paddy growers had medium I explore transformative social innovation in agriculture through a particular case of agroecological innovation, the System of Rice Intensification SRI in India.

India has a rich and vibrant tradition of social innovation wherein vulnerable communities have engaged in collective experimentation. This is often missed in official or formal accounts. Social innovations such as SRI can help recreate these possibilities for change from outside the mainstream due to newer opportunities that networks present in the twenty-first century. I show how local and international networks led by Civil Society Organizations have reinterpreted and reconstructed game-changing macro-trends in agriculture.

This has enabled the articulation and translation of an alternative paradigm for sustainable transitions within agriculture from outside formal research channels. These social innovations, however, encounter stiff opposition from established actors in agricultural research systems.

Newer heterogeneous networks, as witnessed in SRI, provide opportunities for researchers within hierarchical research systems to explore, experiment, and create newer norms of engagement with Civil Society Organizations and farmers.

I emphasize valuing and embedding diversity of practices and institutions at an early stage to enable systems to be more resilient and adaptable in sustainable transitions. The study has examined profitability, sources of productivity improvement and determinants of a new technology-Sustainable Sugarcane Initiative SSI —adoption in sugarcane cultivation in Tamil Nadu by collecting primary data from sugarcane farms during — Although the cost of cultivation has been found higher in SSI method vis-a-vis conventional method, the cost of production is lower due to 26 per cent more cane yield.

The cost and return analysis has indicated that sugarcane cultivation is more profitable under SSI method than under the conventional method. The decomposition analysis has shown that the inputs, viz. The major policy options suggested to improve production and profitability of sugarcane include a provision of drip irrigation with a subsidy, ensuring timely availability of critical inputs and imparting periodical training to farmers on SSI method such as fertigation, wide row spacing, etc.

To meet the rising demand for rice, the staple food in Assam, the production of rice has to be increased by many folds. Considering the shrinkage of agricultural lands, productivity increase is the only way out to increase the production. However, the acceptability of the method by the tradition rice growers of the state is a matter of concern. Further, the resource use status of SRI is yet to be studied systematically in Assam.

The present study on resource use in SRI has shown that the resources used in SRI need to be increased for enhanced rice production the state. Awaring the farmers about SRI and imparting proper training on SRI would certainly help the farmers to increase their rice production to make them rice secured.

System of Rice Intensification provides environmental and economic gains but at the expense of social sustainability — A multidisciplinary analysis in India Author s : Alfred Gathorne-Hardya, D. Narasimha Reddy, M. The System of Rice Intensification SRI is claimed to make rice more sustainable by increasing yields while reducing water demand. However, there remains a shortage of high quality data to test these assertions, and a major research gap exists concerning the wider social and economic implications of SRI techniques.

Using primary data we developed a model to simultaneously analyse social, economic and environmental sustainability greenhouse gas GHG emissions, ground water abstracted, energy use, costs, profit, gender, employment quality and employment quantity to compare SRI to conventional flooded-rice production systems control. Data was based on farmer-recall questionnaires in Andhra Pradesh, India. Analysis was per hectare and per kg of paddy.

However, the socio-economic benefits accrued to the farmer at the expense of landless labourers. Yet with no policy support it is unlikely that the private economic benefits of SRI will be shared to landless labourers. Internalising environmental externalities electricity and GHG impacted control farms more than SRI farms, including producing negative economic returns when electricity was charged at INR4.

Identifying and understanding the trade-offs associated with SRI is essential for policy management — while it is not possible to eliminate all trade-offs, identifying them allows for the mitigation of losers.

Green Revolution?

Meshram, N. Chobitkar and K. Rice is the staple food crop of India, providing 43 per cent of caloric requirement for more than 73 per cent of Indian population. The demand can only be met by maintaining the increase in productivity under decreasing trend of land availability and total factor productivity and has to meet the demands for sustainability and preservation of environment quality.

Assembly of the practices that culminated in SRI began in the s based on Fr. Keeping this in view the study was designed to find out the extent of adoption of recommended practices of SRI technology of paddy cultivation and relationship of the characteristics of paddy growers with their level of adoption. The study was conducted in Balaghat district of Madhya Pradesh during the year to Total respondents were selected on random basis. SRI technology promises the much needed boost to productivity in rice with better water use efficiency.

During the last decade, various agencies promoted this method of rice cultivation in Andhra Pradesh. However, the rate of adoption of SRI method by rice farmers is low.

Environmental Effects of Transgenic Plants: The Scope and Adequacy of Regulation.

The purpose of the study was to understand the needs of the farmers in terms of knowledge and skills which can help improve the adoption rate of the technology. The study indicated that framers have developed positive attitude towards SRI technology.

However, majority of the farmers feel that many of the operations of SRI method are labour intensive and time consuming. They felt the need for training agriculture labour in SRI techniques. Farmers expressed the need for season long contact and support of extension staff with information on irrigation technology and integrated crop management. Durga and D. For efficient use of water, there is a dire need to manage acute water scarcity in agriculture through the adoption of sustainable water management technologies.
