Purpose. The purpose of the article – to assess the technical efficiency of climate adaptation practices on cassava production in two different agro-ecological zones within the study area to know where the climate adaptation practices are more productive. To achieve the main objective of the study, the specific objectives were stated as follows: (a) describe relevant socio-economic characteristics of cassava farmers in southwestern region of Nigeria; (b) assess the influence of the used climate change adaptation strategies on technical efficiency of cassava production in both agro-ecological zones. Methodology / approach. The study was carried out in Ekiti, Osun and Oyo State in the southwestern region of Nigeria, where two different agro-ecological zones (AEZ) (rain forest and guinea savannah) were chosen for the study. The study used multi-stage sampling procedures, with well-structured questionnaire, to select 150 cassava producers from each AEZ, making a total of 300 cassava producers for the study. Data analysis was done using descriptive statistics and stochastic frontier production function. Results. From the study, it was revealed that cassava farmers in the study area were relatively young, fairly educated, mostly married, well experienced, adequately aware of climate change, but operated on a small scale. The result on the influence of climate adaptation strategies on technical efficiency of cassava production in both rain forest and savannah AEZs within the study area revealed that technical inefficiency existed in cassava production as confirmed by the gamma values of 0.687 and 0.639 in rain forest and savannah respectively Originality / scientific novelty. The study has really revealed diverse climate adaptation options available to cassava farmers in order to sustain its production as a means of employment to the unemployed, food consumption and contribution to the national gross domestic product. Studies comparing climate adaptation practices on the technical efficiency of cassava production in different agro-ecological zones in southwestern part of Nigeria are relatively scarce considering the mixture of socio-economic and climate variables to assess technical efficiency of cassava production. Practical value / implications. The study has succeeded in identifying key factors that will enables policy makers to formulate a sustained policy framework that would encourage the use of multiple climate adaptation practices by the cassava farmers. To ensure sustainability of cassava production, it is therefore recommended that farmers should use different adaptation strategies to climate change e.g crop diversification, multiple planting dates, land fragmentation, use of improved varieties and off farm income activities that would bring increase in their scale of operation as most of the cassava farmers in the study areas cultivated less than 2 hectares of land for cassava production.

This study examined farmers’ level of use of climate change adaptation strategies across selected agro-ecological zones in Nigeria. Edo and Ondo States were selected for the study with three major agro-ecological zones. A multi-stage sampling procedure was used. The correlation analysis revealed a significant relationship between year of education and level of use of adaptation strategies (r = 0.15, P = 0.02). The result of Analysis of Variance (ANOVA) revealed that significant differences existed in most of the adaptation strategies employed except planting different varieties (F = 1.672, P = 0.190), intercropping (F = 0.646, P = 0.525), crop rotation (F = 2.436, P = 0.090) and migration to different sites (F = 0.661, P = 0.517). The study recommended that the issue of climate change should not be taken lightly by all stakeholders as its effect differs among various agro-ecological zones.

The study examined the viability of climate adaptation strategies of cassava-based farmers in Southern Nigeria. A total of 300 cassava-based farmers were randomly selected. Primary data were obtained through administration of questionnaire, interview schedule and Focus Group Discussion (FGD). Data were analysed using descriptive statistics which involved the use of percentages, mean and frequency distributions as well as OLS multiple regression model. The specific objectives include: to describe the socio-economic characteristics of the farmers, identify the climate change adaptation practices employed, ascertain the viability of the climate change adaptation practices and to determine the factors influencing the use of climate change adaptation strategies by the cassava-based farmers in the study area. Results show that majority of the cassava-based farmers were females, married, had a mean age of 46 years, 19 years farming experience, household size of 8 persons, and mean farm size of 1.23 hectares. Results further showed that the cassava farmers adopted various of adaptation strategies such as mixed cropping 24.3%, crop rotation 16.3%, change in planting date 36.6%, use of improved varieties 63.2%, minimum tillage 37%, early and late planting 35.3% and 13.5% respectively. These practices facilitated the adaptation to climate change by the farmers. However, farming experience, farm size, education, access to extension  services, credits and farm income influenced the viability of the climatic adaptation strategies of the cassava-based farmers in the area. Farmers are advised to take good advantage of seminars, workshops, symposiums, and conferences on climate change and its implications on agricultural production.

Climate change is expected to have significant impacts on hydrologic regimes and freshwater ecosystems, and yet few basins have adequate numerical models to guide the development of freshwater climate adaptation strategies. Such strategies can build on existing freshwater conservation activities, and incorporate predicted climate change impacts. We illustrate this concept with three case studies. In the Upper Klamath Basin of the western USA, a shift in land management practices would buffer this landscape from a declining snowpack. In the Murray–Darling Basin of south-eastern Australia, identifying the requirements of flood-dependent natural values would better inform the delivery of environmental water in response to reduced runoff and less water. In the Savannah Basin of the south-eastern USA, dam managers are considering technological and engineering upgrades in response to more severe floods and droughts, which would also improve the implementation of recommended environmental flows. Even though the three case studies are in different landscapes, they all contain significant freshwater biodiversity values. These values are threatened by water allocation problems that will be exacerbated by climate change, and yet all provide opportunities for the development of effective climate adaptation strategies.

AbstractEnvironmental health indicators are helpful for tracking and communicating complex health trends, informing science and policy decisions, and evaluating public health actions. When provided on a national scale, they can help inform the general public, policymakers, and public health professionals about important trends in exposures and how well public health systems are preventing those exposures from causing adverse health outcomes. There is a growing need to understand national trends in exposures and health outcomes associated with climate change and the effectiveness of climate adaptation strategies for health. To date, most indicators for health implications of climate change have been designed as independent, individual metrics. This approach fails to take into account how exposure-outcome pathways for climate-attributable health outcomes involve multiple, interconnected components. We propose reframing climate change and health indicators as a linked system of indicators, which can be described as follows: upstream climate drivers affect environmental states, which then determine human exposures, which ultimately lead to health outcomes; these climate-related risks are modified by population vulnerabilities and adaptation strategies. We apply this new conceptual framework to three illustrative climate-sensitive health outcomes and associated exposure-outcome pathways: pollen allergies and asthma, West Nile virus infection, and vibriosis.

Abstract Background: Climate change and variability has been significantly affecting the Ethiopian agricultural production and thereby smallholder farmers livelihoods. The level of vulnerability varied across agro-ecological zones (AEZs). Identification of difference in the level of vulnerability of a system is important in selecting appropriate and effective adaption options to climate change. Therefore, the aim of this study was to analyze the level of vulnerability of agricultural communities to climate change and variability at micro-scale level in five agro-ecological zones (AEZs) of south Wollo, north east highlands of Ethiopia. Data was collected from a representative of 502 sample households from five AEZs through multi stage random sampling methods. Focus group discussion and key informant interviews were also carried out to supplement and substantiate the quantitative data. The indicator based approach was used to empirically calculate vulnerability. Principal Component Analysis (PCA) was applied to give weight for indicators and generate index of vulnerability contributing factors. Results: The results showed that each of the vulnerability contributing factors (exposure, sensitivity and adaptive capacity) varied across the AEZs. M3, SM2 and SM3 are the most exposed AEZs but having a relatively better adaptive capacity whereas M1, M2 and M3 are the most sensitive AEZs with relatively low adaptive capacity to climate variability and change. Overall, SM2 is the most vulnerable AEZ which exhibited high sensitivity and low adaptive capacity followed by M1. Conclusions: The study explored sources and levels of vulnerability to each agro-ecology. Since the study is conducted at micro-scale level, it helps decision makers and development partners to have context-specific understanding of the impact of climate change and variability and design appropriate adaptation measures to address the specific situations.

Previous studies suggested that maize is set to become a cash crop while ensuring food security better than any other crop. However, climate change has become one of the key production constraints that are now hampering and threatening the sustainability of maize production systems. We conducted a study to better understand changes here defined as adaptations made by smallholder farmers to ensure food security and improve income through maize production in a climate change context. Our results show that maize farmers in northern Benin mainly rely on traditional seeds. Drought as abiotic stress is perceived by farmers in many agro-ecological zones as a disruptive factor for crop production, including maize. When drought is associated with pest damages, both the quantity (i.e. yield) and the quality (i.e. attributes) of products/harvests are negatively affected. The adverse effects of drought continue to reduce production in different agro-ecological zones of the country, because of the lack of widespread adoption of tolerant varieties. The study suggests actions towards the production of drought-tolerant maize seeds, a promotion of seed companies, the organization of actors and value chains. Apart from climate change, the promotion of value chains is also emerging as one of the important aspects to take into account to sustain maize production in Benin.
