Purpose The purpose of this paper is to investigate the relationship between gender and social capital in adapting to climate variability in the arid and semi-arid regions in Turkana in Kenya. Design/methodology/approach This paper undertook literature review of secondary data sources, conducted focus group discussions (FGDs) and key informant interviews (KIIs). The statistical package for the social sciences (SPSS) was used to analyze data for the quantitative part of the paper. Findings Vulnerability is influenced by age, gender, education and disability. Elderly women are considered to be the most vulnerable to climate variability and change because they are the poorest in the community, followed by elderly men, the disabled, female-headed households, married women, men and, finally, the youth. Less than 30 per cent of women and men in both Katilu and Loima are able to read and write. The cross-tabulation results show that there is a statistical significant relationship between gender, age and education level and climate change vulnerability. This implies that gender, age and education level have a significant effect on climate change vulnerability. Research limitations/implications The research coverage was limited to only two regions in Turkana because of time and economic constraints. Practical implications The lack of attention to gender in the climate change literature has time and again resulted in an oversimplification of women’s and men's experience of climate risks. Improved development assistance, investments and enhanced targeting of the truly vulnerable within pastoral societies demand an acceptance of underdevelopment in arid and semi-arid regions in Kenya because of historical imbalances in investment; the recognition that vulnerability of pastoralists is neither uniform nor universal and the need to consider differences like age, gender and education. Policy-makers should understand that pastoralists in the past have used indigenous knowledge to cope with and adapt to climate change. The current-recurrent and intensity droughts require investment in modern technology, equipping pastoralists with relevant information and skills to make them resilient to climate change and implementing existing and relevant policies for northern Kenya. Social implications This paper draws from several other efforts to show the critical relationships between gender, social capital and climate change. They are tracking adaptation and measuring development framework; ending drought emergencies common programme framework; and feminist evaluation approach. Originality/value This paper is important in identifying the link between gender, social capital and adaptation to climate change.

Objetivou-se avaliar neste trabalho a influência da variabilidade climática sobre a pluviometria local e, consequentemente sobre a produção agrícola, sobretudo das culturas de milho, feijão e mandioca, responsáveis pelas maiores atuações na renda dos agricultores familiares de Aiuaba (CE). Os resultados das Análises de Ondeletas apontaram ciclos de 5-6 anos (ENOS) para ocorrência de anos chuvosos, consequência da associação de diferentes escalas temporais, enquanto que em anos secos foram observados ciclos entre 4 e 6 anos (ENOS), mostrando que a escala de ENOS influencia em toda série de precipitação. Na falta de associação com as demais escalas temporais ocorreram anos secos. Correlações entre precipitação e todas as variáveis de produção apresentaram-se altas e com significância estatística, manifestando menores correlações apenas entre precipitação e área planta e colhida para a cultura da mandioca, únicas variáveis sem significância estatística. O presente estudo mostrou que as informações geradas para o município são proveitosas para os diversos setores como agrícola e socioeconômico. Notou-se também que a variabilidade climática tem efeitos substanciais na produção da agricultura familiar local.   A B S T R A C T In semi-arid regions such as the county of Aiuaba (CE) the agricultural productivity is more likely to be influenced by edaphoclimatic factors, what beyond of the importance of the producer’s technological level, also influence directly in agriculture. The objective this work was to evaluate the influence of climate variability on the local rainfall and consequently on agricultural production, especially of maize, beans and cassava, account for the greatest performances in the income of farmers of Aiuaba (CE). To reach these objectives were used statistical methods as Correlation and Analysis of Wavelet. The results of the Wavelet analysis pointed cycles of 5-6 years (ENSO) for the occurrence of rainy years, a consequence of several different temporal scales, while in dry years were observed cycles between 4 and 6 years (ENSO), showing that the ENSO scale influence on all series of rainfall. In the absence of association with other timescales occurred dry years. Correlations between rainfall and all production variables were high and with statistical significance, showing only small correlations between rainfall and plant and harvested area for cassava, only variables not statistically significant. This study showed that the information generated for the city are useful for various industries like agriculture and socioeconomic. It was also noted that climate variability has significant effects on the production of local family farmers. Keywords: Climate variability, Family farming, Correlation, Wavelets, ENSO.

Hater resource managers in semi-arid regions are faced with some unique problems. The wide variations in precipitation and stream flows in semi-arid regions increase man's dependence on the ground water resource for an ample and reliable supply of water. Proper management of the ground water resource is absolutely essential to the economic well being of semi-arid regions. Historians have discovered the remains of vanished advanced civilizations based on irrigated agriculture which were ignorant of the importance of proper ground water resource management. In the United States a great deal of effort is presently being expended in the study and control of toxic discharges to the ground water resource. What many public policy makers fail to understand is that the potential loss to society resulting from the mineralization of the ground water resource is potentially much greater than the loss caused by toxic wastes discharges, particularly in developing countries. Appropriations for ground water resource management studies in developed countries such as the United States are presently much less than those for toxic wastes management and should be increased. It is the reponsibility of the water resource professional to emphasize to public policy makers the importance of ground water resource management. Applications of ground water resource management models in the semi-arid Central Valley of California are presented. The results demonstrate the need for proper ground water resource management practices in semi-arid regions and the use of ground water management models as a valuable tool for the water resource manager.
