Financial Liberalization and the Agrarian Sector: India and Kenya Compared
No full textThe agrarian sector in many developing countries has been going through a phase of slowdown, at times aggravating to a crisis, which has called for serious research and introspection into the policies and policy regimes that underlie their development trajectories. This paper looks at one set of important policies, namely the policies of financial liberalisation and traces its linkages with the agrarian sector. It uses the context of two developing economies, India and Kenya that were married to the idea of development banking in the 1950s and 1960s but have liberalized the economy since then, to understand the impact of financial liberalization on the agrarian sector.Financial sector, directed credit, financial liberalization, India, Kenya, agriculture, marketing.
Strengthening Rural Decentralisation: A Study on the Role of International Organisations
No full textThe term ‘decentralisation’ has generally been used to refer to a variety of institutional reforms. It has sometimes been considered as a change in the organisational framework in which political, social and economic decisions are made and implemented. It is also understood as a mechanism to transfer responsibility and authority. In recent years, decentralisation has received singular attention all over the world. It has been considered as one of the most important elements in development strategy. It is a global and regional phenomenon, and most countries have attempted to implement it as a tool for development, as a political philosophy, and as a mechanism for sharing responsibility at different levels.
Since 1980s, developing countries have increasingly adopted decentralised form of governance. Decentralisation means the transfer of authority and responsibility from central to intermediate and local governments. Although the democratic decentralisation in terms of Panchayati Raj Institutions (village councils) was a post-Independence phenomenon, there has been a legacy and tradition of village panchayats since time immemorial in India. The 73rd and 74th Amendment Act, 1993 of the Constitution of India has made the Panchayat an institution of self-government. As per the constitution, Panchayats shall prepare plan for economic development and social justice at their level. The District Planning Committee shall integrate the plan so prepared with the plans prepared by the local bodies at district level. The success and failure of the Panchayats would depend on planning and implementation. It also depends on maximum people’s participation at every stage of planning process, from proposal to implementation. People’s participation in local-level development has been exercised through the formulation of the Panchayat-level development plan, project coordination at intermediate and district levels of the Panchayats.
The Panchayati Raj Institutions (PRIs) in West Bengal are very strong bodies, which function as real institutions of self-governance. In West Bengal, the planning process of grass-root level has some stages from proposal to implementation. After introduction of 3-tier Panchayat system in 1978, the Government of West Bengal brought about need-based reforms in the system from time to time from the very beginning. Encouraged by the State Government’s strong commitment to rural decentralisation, Department for International Development (DFID), Government of UK came forward to support the ongoing rural decentralisation initiatives and upscale the bottom-up planning process. In the present study, an attempt has been made to understand the role of DFID for strengthening decentralisation in rural Bengal
Concentration in Knowledge Output: A case of Economics Journals
No full textThis paper assesses the degree of author concentration in seven economics journals, which were published in India during 1990-2002. To measure the degree of author concentration, Lotka's Law was used. Moreover, we also make an exploratory analysis of the geographic, economics subfield and institutional concentration in 704 economics journals. An important finding of this paper is that specialized journals in the sample report the highest degree of author concentration. This result is quite similar to the findings by Cox and Chung (1991). Furthermore, there are several instances showing that the journals lean towards certain norms; this may affect the flow of innovative ideas into economics. We conclude that a knowledge activity, involving the high degree of concentration and a biased publication process, may affect the flow of new ideas into the discipline.Concentration, Lotka's Law

No full textConsequences of Covid–19 and Role of Gram Panchayats in Tackling the Pandemic Situation
No full textAfter the outbreak of Covid–19 in India, the government of India at the central level promoted several measures to tackle the pandemic situation in the country. While implementing broad socio-economic development programmes and promoting awareness and other support, Delhi also realised the importance of local governance at the grassroots level and suggested that state governments take measures as required at the state and local levels. Considering the specific issues raised at the local level, the state governments appointed their local governance institutions, gram panchayats and municipalities to lead implementation and sensitisation processes. The result was excellent. This article attempts to discuss the consequences of the Covid–19 pandemic and the role of gram panchayats in tackling the pandemic situation, especially in West Bengal

Implementation of field crop practices potentially enables farmers to achieve that desired increase in crop production estimated to be a 60% increase compared to current condition. The CERES-Rice model in DSSAT was used for this study in order to provide the water stress impact on crop production, and best management strategies to improve the rice yield, followed by the calibration and validation with collected field experimental data. Ten-years (2006-2015) of field experimental data were collected from the CIMMYT (International Maize and Wheat Improvement Centre)-BISA (Borlaug Institute for South Asia), Pusa, Bihar, India, research farm for calibration and validation of the CERES-Rice model. Predicted change in climate has significant impact on rice production in Bihar, and thus, will affect food security issues in India and other developing countries. Since rice is the primary food for the majority of Indian people, the focus of this study was to predict the changes in the (a) rice yield and phenological growth, and (b) irrigation water requirement for current yield level as well as 60% increase in rice yield by 2050s (2050-2059) as affected by climate change in the state of Bihar.
The genetic coefficients were developed for the rice variety, Rajendra Mahsuri (predominantly used by more than 90% rice farmers in Bihar), and used for validation of the model. The normalized root means square error (RMSEn) and d-index values were obtained to be 2.73% and 0.62, respectively, for prediction of yield with a model performance efficiency of 75%. The crop model simulation for water stress during vegetative and maturity phase showed to decrease in rice yield by 24% and 33%, respectively, from measured data. However, the water stress during reproductive stage showed the highest reduction in the yield by 43%. Considering the management strategies, where farmers do not need to invest a large amount of resources to increase the rice production, some factors were assessed by sensitivity analysis of the CERES-Rice model. The optimum transplanting date was found to be during the month of June to achieve the highest yield of Rajendra Mahsuri rice. Incorporation of crop residue up to 2500 kg/ha would increase the yield by 22%, compared to the management practices where no residue is applied in the field. Additionally, row spacing of 20 cm increased rice yield by 16-18%, compared to the yield obtained at spacing of 5 cm, and for maximum yield, optimum planting depth was found to be 2 to 4 cm. Keeping a ponding depth of 4-6 cm during crop duration would aid in maximizing the rice yield by 10-15%.
To study the climate change impact on rice yield and water requirement, four GCMs were used for all four climate change scenarios (RCP 2.6, RCP 4.5, RCP 6.0 and RCP 8.5). The projected changes in climatic variables showed the change in future climate during 2020-2059 from baseline period (1980-2004). A Taylor diagram was constructed to analyze the relationship between the historical observed and simulated climate data; Mann-Kendall trend test for climate data of each GCM revealed the trend in climate from 2020-2059 for the climate change scenarios (RCP 2.6, RCP 4.5, RCP 6.0 and RCP 8.5). Further, in order to increase the rice production by 60% during the 2050s, the irrigation requirement for all four climate change scenarios was computed based on the percentage of yield productivity from irrigation water. The results showed that the precipitation amount increased from 2020 to 2059, and hence, the irrigation requirement was predicted not to be as much higher as one would expect for a 60% increase in crop yield. Yield increase by the year of 2059 also partly accounted by an increase in CO2 concentration as predicted by all climate change scenarios. We investigated several strategies, such as conservation agriculture (direct-seeded rice with residue application) and reduction of post-harvest loss, to reduce the water requirement to produce 60% more rice by 2059. Moreover, if we combine both conservation agriculture and removal of 30% of postharvest losses, the irrigation requirement would be reduced by 26% (45 to 19%), 20% (44 to 24%), 21% (43 to 22%), 22% (39 to 17%), and 20% (41 to 21%) with current, RCP 2.6, RCP 4.5, RCP 6.0 and RCP 8.5 conditions, respectively.
The assessment on rice production with default value of CO2 concentration (400 ppm) during 2020-2059 demonstrated a decrease in rice yield and phenological days, but increase in water demand. The increase in water demand was found due to reduction in CO2 concentration, which increases the water use efficiency. Larger the differences between default and changed CO2 concentration (as predicted by the climate change scenarios), larger were the deviations between all the outputs. During 2050s, the maximum reduction in yield was 23% with RCP 8.5 and the lowest reduction of 15% was observed with RCP 2.6. Similarly, water demand increased due to decrease in CO2 concentration. The maximum decrease in phenological days was estimated to be 14 days with worst-case scenario (RCP 8.5).
Since most farmers in the state of Bihar only produce Rajendra Mahsuri rice variety, this information can help in planning for maximizing production of this rice variety and decreasing water requirement strategies in the state of Bihar, India and similar other locations, where water availability would be severely impacted by climate change.Submission published under a 24 month embargo labeled 'Closed Access', the embargo will last until 2021-05-01The student, Ranjeet Kumar Jha, accepted the attached license on 2019-04-15 at 15:42.The student, Ranjeet Kumar Jha, submitted this Dissertation for approval on 2019-04-15 at 15:43.This Dissertation was approved for publication on 2019-04-17 at 11:50.DSpace SAF Submission Ingestion Package generated from Vireo submission #13638 on 2019-08-22 at 16:21:29Made available in DSpace on 2019-08-23T20:47:25Z (GMT).
