Purpose This paper aims to examine elderly smallholder farmers’ perceptions of and adaptation to climate variability and change in the Offinso Municipality, Ghana. Design/methodology/approach This paper used quantitative and qualitative methods. Quantitative data were analyzed with frequencies and chi-square tests, whereas qualitative data were thematically analyzed. Findings The results showed that elderly smallholder farmers’ knowledge of climate variability and climate change were based on their sex, level of formal education and experience in farming. Elderly smallholder farmers adopted both on-farm and off-farm strategies to cope with climate change and variability. The vulnerability of elderly smallholder farmers to climate change calls for social protection mechanisms such as a pension scheme that guarantees access to monthly cash transfers. Such a scheme will ease constraints to livelihood and ensure improved well-being. Originality/value Elderly smallholder farmers have remained invisible in discourses on perceptions and adaptation to climate change despite the surge in number of this category of farmers. This paper therefore represents an attempt to highlight the experiences of elderly smallholder farmers with climate variability and change.

Climate variability and change has caused instability in production and decline in productivity exacerbating food insecurity particularly in Latin America, Africa including Ethiopia and some parts of Asia. The magnitude and frequency of extreme climatic events is projected to increase. The effects of these climatic changes will become even more pronounced among small scale farmers whose farming activities are weather dependent and vulnerable to climate change, and already affected by environmental degradation and socio-economic risks. Effective adaptation to climate change among small scale farmers is therefore of critical importance, and is dependent on adoption of climate smart practices. However, studies have shown low adoption of climate smart farming practices among small scale farmers world over, in East Hararghe Zone and Kurfa Chele District. This study therefore examined factors influencing adoption of climate smart practices among farmers Kurfa Chele District, East Hararghe Zone, evaluated their existing knowledge, attitude and practice of these practices, assessed their perception of climate change, examined the extent of climate information dissemination, and the resultant impact on uptake of these practices. The research adopted a survey research design, where both quantitative and qualitative research strategies were used. Data was gathered through Focus Group Discussions, questionnaires, key informant interviews, observations and desk review. Both simple random and purposive sampling was used to sample 420 small scale farmers and technical officers of the agriculture sector respectively. Data was analysed using both quantitative and qualitative techniques. To test the statistical significance of the findings and relationships between the variables, chi-square test was used.

Climate change implies changes in the frequency and magnitude of flood events. The influence of climate variability on flooding was evaluated by an analysis of sedimentary (palaeofloods) and documentary archives. A 500-year palaeoflood record at Montlleó River (657 km2 in catchment area), eastern Spain, revealed up to 31 palaeofloods with a range of discharges of 20–950 m3 s−1, and with at least five floods exceeding 740–950 m3 s−1. This information contrasts with the available gauged flood registers (since year 1971) with an annual maximum daily discharge of 129 m3 s−1. Our palaeoflood dataset indicates flood cluster episodes at (1) 1570–1620, (2) 1775–1795, (3) 1850–1890, and (4) 1920–1969. Flood rich periods 1 and 3 corresponded to cooler than usual (about 0.3 °C and 0.2 °C) climate oscillations, whereas 2 and 4 were characterised by higher inter-annual climatic variability (floods and droughts). This high inter-annual rainfall variability increased over the last 150 years, leading to a reduction of annual maximum flow. Flood quantiles (>50 years) calculated from palaeoflood+gauged data showed 30%–40% higher peak discharges than those using only instrumental records, whereas when increasing the catchment area (1500 km2) the discharge estimation variance decreased to ~15%. The results reflect the higher sensitivity of small catchments to changes on flood magnitude and frequency due to climate variability whereas a larger catchment buffers the response due to the limited extent of convective storms. Our findings show that extended flood records provide robust knowledge about hazardous flooding that can assist in the prioritization of low-regret actions for flood-risk adaptation to climate change.

Nepalese people have experienced climate variability for a long time and the mitigation and adaptation responses they have made to reduce the effect of climate variability are not new phenomena for Nepal. However, mainstreaming climate change issues into sectoral policies from the government can be seen as recent activities in Nepal. Nepal has contributed negligible amount of emissions of Greenhouse Gases (GHGs) of global greenhouse gas, it is the fourth most vulnerable country in the world. In this context, this paper aims to review climate change adaptation policies in terms of sectoral integration. This paper has adopted text-mining method for information retrieval and knowledge mining and followed step-by-step approach to undertake review of policies. It concludes that National Adaptation Programme of Action (NAPA) in 2010 can be a milestone in sectoral adaptation of climate change issue largely because it has provided the national framework for sectoral adaptation to climate change. However, NAPA ignores the importance of structural and institutional reforms needed for mainstreaming climate change adaptation into sectoral agencies. Climate change Policy, 2011, Local Adaptation Plan of Action (LAPA) 2011, Constitution of Nepal, 2015, Local Government Operation Act (LGOA) 2017, Disaster Risk Reduction and Management Act, 2017 and National REDD+ Strategy, 2018 are other prominent legislative and policy frameworks that have significant contribution in sectoral integration of climate change adaptation issues. However, lack of climate change act in order to implement fully these policies into practice for its implementation can be a major obstacle to achieve the goal. In this context, strong legislative foundation with effective institutional mechanism among different sectors will be very crucial to capture the spirit of new Federal Constitution of Nepal.

As growing attention is paid to climate change adaptation as an actual policy issue, the significant meaning of climate variability in adaptation decisions is beginning to be recognized. By using a real option framework for adaptation in agricultural production, we shed light on how climate change and climate variability affect individuals' (farmers') investment decisions with regard to adaptation (switching from rainfed to irrigated farming). The option value delays adaptation easily for several decades with a realistic set of parameter levels, implying a critical role of risk sharing in promoting adaptation. When variability-influenced adaptation involves the use of an open-access resource (groundwater), uncoordinated farmers may adapt too early or too late depending on the level of their risk aversion. Private adaptation should be supported or discouraged accordingly if coordination is infeasible or farmers are not convinced about the possibilities of collective resource management in the long run.
