This study investigates implications of crop and income diversifications on consumption expenditure (welfare) of rice-producing households in Ghana. It further compares diversification by three rice production systems: two-season rain-fed, two-season irrigated and one-season rain-fed rice production.

Primary data were sourced from 225 rice farmers. Margalef index and three-stage least-squares were employed.

Majority of rice-farming households in Ghana diversify livelihoods. The extent of livelihood diversification differs among two-season rain-fed, two-season irrigated and one-season rain-fed rice-producing households. Credit, distance to district capitals, production purpose and number of farming seasons influence crop and income diversifications, and consumption expenditure of rice-producing households. While crop diversification reduces consumption expenditure, income diversification increases it. Crop and income diversifications positively influence each other. Consumption expenditure reduces crop diversification but increases income diversification.

Policy should be directed towards the promotion of more livelihood activities to boost rice farmers' welfare. There should be awareness creation and training programmes to enable rice farmers realize different economic activities within and outside the agricultural value chain.

Crop and income diversifications were measured as continuous response variables, unlike previous studies that used a binary response variable. The authors established a synergy among crop and income diversifications, and consumption expenditure (welfare). The authors further compared crop and income diversifications by three rice production systems: two-season rain-fed, two-season irrigated and one-season rain-fed rice production systems.

HERALDED by a leading article in The Times which appeared on the morning of its publication, the Report on the Public Libraries System of Great Britain by Mr. Lionel R. McColvin is now available. It will, without doubt, be the most carefully read current work in its own field, and its suggestions will be subjected to the closest scrutiny. Our correspondent in “Letters on Our Affairs” makes the first step in our pages in this direction, although, as he indicates, his views are merely preliminary. Last month we suggested that if such a report were issued by the Library Association, it should be made quite clear that it is the pronouncement of an individual and not an official document in the strict sense. Already, of course, as The Times leader seems to suggest, the distinction between Mr. McColvin's work and the views of the Library Association have been confused in the public mind. That was inevitable. But we understand that the Association at a later time will issue its own considered statement of what it thinks to be necessary and practicable in the re‐construction of the library service—if, indeed, it is reconstructed—to meet after‐war needs. On the whole, the book is quite readable and betrays very little of the hurry in which it must have been written: its facts seem to be sound and marshalled with considerable skill; its general outlook is generous. With much of it there will not only be agreement; there will be enthusiastic agreement. In so far as it is a proposed system for post‐war organization, it follows the lines already suggested by the Regional Systems created for Civil Defence, involving larger library areas administered from what Mr. McColvin believes to be the central town or other focus of each area. The counties as such disappear, the smaller towns and villages merge into the central town, and so we get in one way or another a cohesive, self‐sufficient and mutually supporting set of libraries in each area. It is around the choice of area and all its implications that discussion will rage and upon which it will be most difficult to obtain general consent. These units, however, while essential to Mr. McColvin's scheme, cannot be regarded other than as proposals to be discussed. Librarians will be quick to see that many of them will become branch librarians if the scheme matures, but in every one of the many schemes we have seen for post‐war re‐construction, larger units than the present ones are invariably implied, and this of necessity means the disappearance as chief officers of many now holding office. This is only one item in a whole series of discussable proposals. We hope that every one or our readers will study the Report and will bring to the common discussions that must be forthcoming a complete and, we hope, impartial understanding of what is involved.

MANY and sundry are the worries which fall to the lot of the librarian, and the matter of book‐repair is not the least among them. The very limited book‐fund at the disposal of most public library authorities makes it imperative on the part of the librarian to keep the books in his charge in circulation as long as possible, and to do this at a comparatively small cost, in spite of poor paper, poor binding, careless repairing, and unqualified assistants. This presents a problem which to some extent can be solved by the establishment of a small bindery or repairing department, under the control of an assistant who understands the technique of bookbinding.

The construction business is widely recognised for its inherent complexity and dynamic nature, which stems from the nature of the job involved. The industry is often regarded as one of the most challenging industries globally in terms of implementing environmental, health and safety (EHS) practices. However, in the absence of EHS, the construction industry cannot be considered sustainable. Therefore, this study aims to identify the trends, knowledge gaps and implications of EHS research to enhance construction activities and knowledge.

The study adopted a science mapping approach involving bibliometric and scientometric analysis of 407 construction EHS publications from the Scopus database with the VOSviewer software. The study is based on journal articles from the Scopus database without restriction to any time range.

The main focus of construction EHS research identified in the study includes sustainability-related studies, risk-related, environmental issues, EHS management, integrated management systems studies, health and safety related and EHS in the construction process. Some emerging areas also identified include productivity, design, culture, social sustainability and machine learning. The most influential and productive publication sources, countries/regions and EHS publications with the highest impact were also determined.

Documents published in the Scopus database were considered for analysis because of the wider coverage of the database. Journal articles written in English language represent the inclusion criteria, whereas other documents were excluded from the analysis. The study also limited the search to articles with the engineering subject area.

The research findings will enlighten stakeholders and practitioners on the focal knowledge areas in the EHS research domain, which are vital for enhancing EHS in the industry.

To the best of the authors’ knowledge, this review-based study is the first attempt to internationally conduct a science mapping on extant literature in the EHS research domain through bibliometric and scientometric assessments.
