One of the objectives of smart village is the efficient use of regional resources by local people to improve economic, social and environment conditions. Small-scale dairy farm (SDFs) exist in every village of India, contributing significantly to local economy and welfare of few families. The purpose of this work is to develop a mechanism to make SDF not only efficient but effective in operations.

A systems thinking approach is used to identify the variables influencing a SDF and develop a general framework – RAMHI (resources, alternate revenue, manpower, herd and infrastructure) comprising endogenous and exogenous variables. A representative SDF as a case study was chosen to implement RAMHI and assess its implementation feasibility and economic benefits.

Implementation of RAMHI gradually improves the economic benefits of a SDF. The key performing indicators like average milk produced/day; milk revenue/fodder cost; number of successful artificial insemination (AI) of herd/number of AI of herd; milking cow/dry cow; and milking cow/total cow, increased substantially in two successive years.

The literature reported and discussed individual variables influencing functioning of SDF while there are few conceptual frameworks proposed, comprising not more than three variables. This paper not only presents a comprehensive generalized framework – RAMHI, which comprises five variables like resources, alternate revenue, manpower, herd and infrastructure but also explains the implementation strategy and its benefits using a case study.

At a meeting of the Council of the Royal Borough of Kensington on June 5th Councillor A. J. RICE‐OXLEY, M.D., Chairman of the Public Health Committee, brought up a report as follows:—

A novel cost-effective bio-digester was explored to convert biological waste into useful clean energy. The bioreactor was aimed to anaerobically digest locally sourced cow dung and chicken droppings.

The design consideration is a batch horizontal 267 L digester made from cast iron with centrally positioned four-impeller shaft to enhance mixing. The system operated with a retention time of 63 days and a substrate (cow dung and poultry waste) ratio of 1:2 and water substrate ratio of 1:0.5 in the gasholder system. The purification, compression and performance evaluation of the generated biogas were also conducted.

The total volume of gas produced for each substrate compositions designed over 14 days ranges between 49.34 and 52.91 mL/day. The optimal value of 52.45 ml using cow dung and poultry waste (w/w) 20:80 was obtained. The average ambient temperatures during the study were within the mesophilic range of 20-40°C. The pH values were stable and always in the optimal range of 6.5-8.0. The reductions in moisture content, ash content, total solids and volatile solids were from 80.50-0.20 per cent, 39.60-14 per cent, 18.50-5.90 per cent and 11.60-4.90 per cent, respectively.

The developed digester is cost-effective and would help minimize solid waste disposal. The estimated methane contents of the gas from cow dung and chicken waste after scrubbing were found to be 71.95 per cent and could be harnessed in solving the energy crisis in the developing nations.

Town Clerk's Office, Town Hall, Bethnal Green, E. 18th November, 1916. To the Chairman and Members of the Public Health Committee. Mr. Chairman and Gentlemen, At a recent meeting of the Public Health Committee, the Chief Sanitary Inspector reported upon legal proceedings which had been unsuccessful owing to the case of “Hunt v. Richardson” decided by a King's Bench Divisional Court of five Judges on the 2nd June, 1916, and I then reported upon the legal aspect of the case.

The purpose of this paper is to assess the exposure of cooks in rural India (55 households) to the indoor air pollution levels emitted from burning of different fuels, i.e. cow dung, wood, liquefied petroleum gas (LPG) and propane natural gas(PNG) kerosene for cooking purposes.

Indoor air quality was monitored during cooking hours in 55 rural households to estimate the emissions of PM10, PM2.5, CO, NO₂, VOCs and polyaromatic hydrocarbons (PAHs). While, PM10 and PM2.5 were monitored using personal dust samplers on quartz filter paper, CO and VOCs were monitored using on line monitors. The PM10 and PM2.5 mass collected on filter papers was processed to analyse the presence of PAHs using GC.

Results revealed that cow dung is the most polluting fuel with maximum emissions of PM10, PM 2.5, VOCs, CO, NO₂ and Benzene followed by wood and kerosene. Interestingly kerosene combustion emits the highest amount of PAHs. Emissions for all the fuels show the presence of carcinogenic PAHs which could be a serious health concern. The composition of LPG/PNG leads to reductions of pollutants because of better combustion process. LPG which is largely propane and butane, and PNG which is 90 per cent methane prove to be healthier fuels. Based on the results, the authors suggest that technological intervention is required to replace the traditional stoves with improved fuel efficient stoves.

The prevailing weather condition and design of the kitchen in these rural houses severely affect the concentration of pollutants in the kitchen as winter season combined with inadequate ventilation leads to reduced dispersion and accumulation of air pollutants in small kitchens.

The present study provides a detailed analysis of impact of widely‐used cooking practices in India. Even today, countries such as India rely on biomass for cooking practices exposing the cooks to high level of carcinogenic pollutants. Further, women and girls are the most threatened group as they are the primary cooks in these rural Indian settings. Based on the results, the authors suggest that technological as well as policy intervention is required to replace the traditional stoves with improved fuel efficient stoves.

The question of the best commercial method of retailing milk requires to be dealt with from the various standpoints of the different classes of milk vendors.

This study acclaims the social entrepreneurship based on cow rearing experiential tourism in Himachal Pradesh. This study aims to illustrate the role of indigenous cows in the Indian society, especially in the Northern Mountain regions by taking Kangra district of Himachal Pradesh as an exemplar. This study highlights the relevance of experiential tourism that elucidates on the basis of cow tourism pertaining to health, mental and spiritual rejuvenation. Lastly, the paper is an attempt to integrate social entrepreneurship and cow tourism highlighting the relevance of experiential economy in empowering the local community.

The case study elucidates on the whence of Swadeshi Kamdhenu Gaushala (SKG), an initiative of Mr Rishi Dogra and Mr Rajesh Dogra, their immaculate micro-management and its benefits to the local community. It highlights how SKG is uplifting the socio-economic standards of the local villagers and providing a distinctive learning experience of indigenous knowledge to visitors. This study is qualitative in nature that uses narrative analysis of secondary data to recognise the importance of indigenous Indian cows, and case study analysis of interviews of SKG proprietors to understand the micro-management, production of organic products and community engagement in their social entrepreneurship.

The SKG is not only helping the local community in their livelihood but also creating value and positioning to the place on the tourist map. This study sheds some light on the importance of cow products in sectors such as agriculture, green energy and for human health and nutrition. The study also crystallizes the challenges faced by the cow rearers, at last the paper sorted out the benefits of cow tourism and how it can result in community empowerment and development.

The case study on SKG helps us in understanding the importance of social entrepreneurs in community empowerment and also the intervention of tourism in the sector that can bring new and different vertical to the tourism industry with experiential learning of the tourist, which results in knowledge sharing about the benefits of Indian cows and helps in creating and placing such destinations on tourist maps. This study attempts towards contributing to the existing knowledge, highlighting the benefits of social entrepreneurship and cow tourism for the society in general and local community in particular.

In a recent article upon the improper handling of meat, the Daily Mail observed that if the public realised the condition of much of the meat delivered to them there would be such an outcry that the Ministry of Health would be compelled to issue definite regulations governing the transport and sale of meat. London butchers are not the worst offenders. Many of them conform voluntarily to standards of hygiene that are far better than in many provincial towns where the public health authorities are lax; but even in London it is possible, in every district, to see revolting methods of dealing with meat. The great Central Meat Market at Smithfield is under the control of the Corporation of the City of London. There are definite orders that meat porters must wear white overalls and caps in addition to various sanitary regulations as to the transport of meat. Many men disobey them with impunity. Among incidents seen there by a representative of the Daily Mail were :—Porters with filthy tweed caps and still filthier sacking carrying carcases on their shoulders; carcases of mutton lying unprotected on a muddy pavement; a scavenger sweeping up dust and manure just beneath an open cart loaded with mutton; a boy with muddy boots and grimy clothes sitting on a heap of meat in another open‐end cart. If the orders of the Ministry cannot be enforced at Smithfield it is not surprising that they are utterly ignored in other places. More than half the butchers' shops seen in a long tour of London neglected the most elementary precautions against the contamination of meat from dust and dirt. The following are some typical examples:—Meat exposed in trays on the pavement, with a marble shop wall behind absolutely black with dirt and mud splashes ; a road‐sweeping machine spraying dirt on to joints exposed without any covering on a stall in the gutter outside a butcher's shop; refuse from a dust‐cart blowing on to meat in another open‐fronted shop; cooked meats exposed in an open window in one of the busiest streets in London. The Ministry of Health, in an explanatory memorandum, expressly excluded cooked meat from the operation of any regulations. Yet, as Medical Officers of Health point out, cooked meat, since it is eaten as bought, is a more dangerous carrier of infection than raw meat. The Ministry, it is understood, “ hope to be able to issue regulations dealing with the sale of cooked meat some time,” but cannot say when or promise an early date. The whole fault, for which the public have to pay the toll of disease due to dirty meat, is in the vagueness of the regulations made by the Ministry a year ago.

At a meeting of the Council of the Royal Borough of Kensington on the 9th May, Councillor R. DUDLEY BAXTER, Chairman of the Law and General Purposes Committee of the Council, brought up a Report as follows:—

A new approach in the field of renewable energy is- the microbial fuel cells (MFCs). It is a technique to produce bioelectricity from available organic waste. It is helpful to fulfill the lighting requirements of rural areas. The aim of our research work is to construct twocompartment system and to study various parameters like performance of the different combination of electrodes, optimization of pH and temperature. In this study, using bacteria as biocatalyst, the naturally found cow dung was used to generate an open circuit voltage of 0.84 ± 0.010 V and a current of 3.51 ± 0.620 mA. Optimization of various parameters shows that among different temperature range, 37°C temperature gives the highest voltage production of 0.84 ± 0.091 V and current of 3.08 ± 0.512 mA. In case of pH there are not any significant changes were found when pH range is changed. Although, pH 4.0 is found to be more efficient as it produces voltage of 0.90 ± 0.045 V and current of 4.85 ± 0.587 mA. Furthermore, three electrogenic bacterial strains were isolated and studied for their electrogenic properties individually and among them CDB-3 was found best in their performance.
