Technology for Dry Farming: How Do the Scientists, Students & Farmers View the Challenge?

Anil K. Gupta

An exploratory study of scientific goal setting in dry farming areas was pursued during 1985. The post-graduate students as well as scientists engaged in dry farming research from a North Indian agricultural university and its regional station were interviewed besides the scientists from All India Coordinated Research Project on Dryland Agriculture, Hyderabad. The farmers operating in the hinterland of the university as well as regional station were also contacted to contrast their perception with that of the scientists. Perception of scientists regarding indigenous technology developed by the farmers was studied to understand the match or mis-match existing between their perception vis-à-vis that of the farmers. The post-graduate research pursed in different universities during 1973 to 1983 in five disciplines viz., Agronomy, Genetics and Plant Breeding, Economics, Extension and Sociology was analyzed to understand the type of the skills which are being built up for facing the challenge of 21st century. The policy implications for making dry farming research more attractive for the post-graduate students and the concerned scientists have been given. The need for restructuring the approach to dry farming research management has been underlined. The contribution of ecological variables as distinct from economic variables in the choice of technology by the farmers have also been studied.

Role of Women in Risk Adjustment in Drought Prone Regions

Anil K. Gupta, Yugandhar Mandavkar, Amin Surekha, and Shah Rekha N

Households strategies for adjustment with risks is an understudied subject, in general but role of women in this regard has remained particularly neglected. Author had taken up a comprehensive study of Impoverishment in Drought Prone Regions in collaborations with Swiss Dev Corporation and NABARD during 1981 in a drought prone district (Ahmednagar) of Maharashtra. The purpose was to identify the policy options for rural credit for drought prone regions. Subsequently during 1985-86, some of the women member of the households were revisited to understand the changes if any in terms of repertoire of the risk adjustment strategies. The paper summarizes some of the ways in which rural women contribute towards risk adjustment with special reference to the problems of credit. This is a preliminary draft and a more comprehensive study will be separately brought out.

Optimal Consumption Plans with Uncertain Planning Periods

Lahiri Somdeb

In this paper we study the one sector optimal growth model with uncertain planning horizons. We prove the non-existence of steady states, and the dependence of optimal capital stock at time 't' on the conditional probability of a 't' period planning horizon given that the planning process does not terminate before time 't'. We illustrate our results using a consumption optimal growth model and Cobb-Douglas technology.

Priority Areas for Research in the Operations of Small Enterprises

Srivastava Uma Kant

Failure and sickness of small venture during project cycle has received very little attention by the developmental institutions, specialized research institutions and management specialists. Failure and sickness is caused due to problems in pre-operative and operative phases of a project. In operative phase, which broadly could be considered as project pre-planning and implementation phase, internal and external factors cause delay in project implementation. Delay in implementation often seriously jeopardizes the financial viability of the project right from the initial stage. Major problems in operative phase include faulty project formulation and implementation, non-availability of raw materials, poor financial management, training and retraining of manpower, marketing problems and technical problems associated with production. Survey research and case research are important methods of research in small ventures. Survey research is not only time consuming but also does not provide insight at micro-level into the reasons, which lead to failure and sickness in small ventures. Case researches of selected small enterprises from various regions of the country can be an extremely effective tool for generating the required understanding of small business. It is desirable that major specialized research institutes should take the lead in generating ideas and providing regional and state levels should pool the researches and share the funding with each other.

Considerations in Evolving a Comprehensive Leasing Policy for Inland Waterbodies for Fish Production

Srivastava Uma Kant

Inland fishery resources can be classified in terms of rivers, fresh water ponds, reservoirs and brackish water bodies (ponds for culture, term's farms for capture/filtration, lakes, swamps and estuaries). Some States have made an attempt to license the river stretches to the fishermen for a small fee but in view of the declining catches from the reverie resources, it is doubtful whether reverie fishermen in Gujarat can be made to pay anything. There is, however, a need for conservation of fish breeding and genetic resources in the reverie sector. The question of lease/royalty is important for the other three sub-systems of inland sector i.e. fresh water ponds, reservoirs and brackish water water-bodies. This paper is designed to highlight some of the critical elements in decision-making about the leasing of these water-bodies. The paper makes recommendations for the lease duration, rent and institutional support for each of the inland fishery sub-systems.

Marketing of Fresh Water Fishes in India

Srivastava Uma Kant

In this paper an attempt has been made to analyze the marketing pattern (use flows, physical flows, channel flows and fishermen's share in consumer rupee) of fresh water fishes and to summarize the key areas for action to improve the marketing system and farmer's share in consumer rupee. Before discussing the marketing pattern, demand-supply scenario, price behavior of fish vis-à-vis other commodities and role of inland fisheries in meeting the demand is presented. The most important concern for improving the fish marketing system is to give larger share of consumer's rupee to fisherman/fish farmers. As the same time availability of fish to consumers including those located in the hinterland, need to be assured at reasonable prices. Keeping these two major concerns in view, following areas of actions can be suggested for improving inland fish marketing system: (i) Market Regulations, Weights and Measurements, (ii) Strengthening of Transit-and-Terminal Markets and setting up of Retail Markets, (iii) Packing and Transportation, and (iv) Vertical Integration of Cooperative from Primary to Transit and Terminal Markets.

Scientific Perception of Farmers Innovations in Dry regions: Barriers to the Scientific Curiosity

Anil K. Gupta

Surprise is a necessary condition for making a discovery. If a phenomenon out there does not surprise us and thus is not noted by us, could it be because of the familiarity that we have with it. In that case, is perception of an innovation and function of individual theory of social change or activity. The question of local agricultural knowledge not being perceived by agricultural scientists was raised in a study on Matching Farmers' Concerns with Technologists' Objectives: A Study of Scientific Goal Setting in Dry Farming. Paper deals with two questions: (1) How do we classify local/indigenous knowledge and (2) why don't scientists pursue some of these practices further to draw science out of these or to build upon these.
