Nyandarua County of Kenya has been for a long time, manifested itself as one of the major food baskets in the country. This is because of its high and sustainable output in crop farming i.e., maize, Irish potatoes, wheat, and other horticultural crops like vegetables and fruits. However, this scenario has recently changed because the usual high crop output has not been forthcoming due to recent changes in climatic patterns where rainfall has become very unreliable and temperatures very extreme. In an attempt to adapt to this climate variability and its associated negative impacts on crop farming, smallholder farmers have tried to apply the greenhouse farming technology for them to be able to maintain and or improve the various crop output amid the climatic changes. The study aims to examine and assess the socio-economic determinants and constraints associated with this attempt of adaptation strategy. Using the primary data of 300 respondents (Smallholder farmers) in the County, the study adopted a logistic regression analysis model to associate the demographic, socio-economic, and constraints encountered by the smallholder farmers with the adoption of the greenhouse farming technology. The study results indicate that this adaptation strategy was reported by 25 out the 300 smallholder farmers (5.83%). The study results further suggest that financial constraints (27%) and lack of information (22.3%) are the major constraints preventing smallholder farmers from effectively adopting this adaptation strategy. However, the probability results of logistic regression analysis (68%) indicate that if properly adopted, the method can provide a solution to the currently reduced food shortages and increase food security among the smallholder farmers of Nyandarua County of Kenya.

Abstract
Background: At the centre of smallholders’ adaptation is a need to understand their perceptions on key climatic
scenarios so as to glean helpful information for key decision-making processes. In Kenya at the moment, downstream
information regarding these circumstances remain scanty, with many smallholders being ‘on their own’, in spite of the
imminent threats from shifting precipitation patterns, rising temperatures, and intensifying droughts. At the sub-national
levels, potential impacts of these situations are likely to deepen due to extensive cases of land use transformations,
habitat degradation, plummeting water resources capacity and common inter-ethnic conflicts, among other negative
externalities. The study examined current climatic situations in Trans-Mara East sub-County, to the south-western part of
Kenya, as well as the smallholders’ perceptions about the situations, their adaptation levels and constraints thereof.
Results: Pearson correlation coefficient, indicated a weak positive association between smallholder’s perceptions and
either their age, marital status, level of education, or livelihood streams (r ≤ 0.1; p ≥ 0.05, for all), unlike their climatic
perceptions and farm sizes which showed a strong positive association (r = 0.430; p ≤ 0.01). Key desired adaptation
options, improving crop varieties, livestock feeding techniques and crop diversification, topped their options, with
destocking being least desired. Education levels (r = 0.229; p ≤ 0.05) and farm sizes (r = 0.534; p ≤ 0.01) had a positively
significant association with adaptive capacity, in addition to a significantly weak, association between their adaptive
capacity and both their individual’s marital status (r = 0.154; p ≥ 0.05) and diversity of livelihood streams (r = 0.034;
p ≥ 0.05). The analysis also showed a weak negative association between their adaptive capacity and age (r = − 0.026;
p ≥ 0.05). Amid the key constraints which emerged include high cost of farm inputs, limited access to credit and
market uncertainties, among others. Pearson correlation coefficient showed a significantly strong negative association
between smallholders’ constraints and both (r ≥ − 0.3; p ≤ 0.01) their level of education, and diversity of livelihood
streams. A significantly strong positive association (r = 0.280; p ≤ 0.01) was identified between smallholder’s age and
constraints, while marital status and farm sizes both (r ≤ − 0.01; p ≥ 0.05) revealed weak non-significant negative
association with the constraints.

Although military conflicts are common on the African continent, there is a paucity of data regarding bomb-blast injuries in this region and in Kenya in particular. This paper describes the pattern of maxillofacial injuries sustained after the August 1998 bomb blast that occurred in Nairobi, Kenya. A retrospective cross-sectional study was carried out using hospital-based records of 290 bomb-blast survivors admitted at the Kenyatta National Referral and Teaching Hospital in Nairobi. Using a self-designed form to record information about variables such as the sex and age of the survivors and type of location of soft- and hard-tissue injuries, it was found that of the 290 bomb-blast survivors, 78% had sustained one or more maxillofacial injuries. Soft-tissue injuries (cuts, lacerations or bruises) were the most common, constituting 61.3% of all injuries in the maxillofacial region; 27.6% had severe eye injuries, while 1.4% had fractures in the cranio-facial region. This paper concludes that the effective management of bomb-blast injuries as well as those caused by other types of disaster requires a multidisciplinary approach. The high percentage of maxillofacial injuries confirm that maxillofacial surgeons should form an integral part of this multidisciplinary team.
