Rapid change in climate is set to alter the delicate balance that exists between man and nature. The literature to this effect points out that the poorest countries and communities are likely to suffer the most because of their geographic locations, low income and low institutional capacity, as well as their greater reliance on climate-sensitive sectors like agriculture. Even if climate mitigations plans are implemented properly there will be some degree of warming due to inertia of emissions already released. As such, there is a strong consensus about the need of adaptation to changing climatic conditions. Adaptation to climate change is given increasing international attention as the confidence in climate change projections is getting higher. Developing countries have specific needs for adaptation due to high vulnerabilities, and they will in this way carry a great part of the global costs of climate change although the rising atmospheric greenhouse gas concentrations are mainly the responsibility of industrialized countries. Adaptation is believed to enhance the resilience against increasing climate variability. In this backdrop, the objective of the present paper is, therefore, to systematically and critically review the existing literature on the impacts of climate change and choice of adaptations across countries and draw insights for suggesting a comprehensive policy framework particularly for developing countries in this regard. The paper finds that the role of government and civil society is crucial for enabling efficient adaptation methods. Development policies and programs having synergy effect with climate change initiatives help adapt with the changing climate better. However, the availability of clean technology in developing countries will play the decisive role in controlling their growth rate of emission.

The willingness of farmers to pay for improved teff seed has positive effects on utilization of improved teff which increases agricultural production, productivity rural household income. However, the extent to which the willingness of teff producers to pay for improved teff seed was not studied in the study area. Hence, the primary goal of the study was to examine the willingness to pay for improved teff seed in Yilmana-Dinsa woreda, West Gojjam Zone. To collect quantitative and qualitative data, both primary and secondary sources were employed from 121 sampled respondents. The data were examined using expressive and inferential (t-test and chi-square test) statistics and econometric model (bivariate probit). The result showed that 79.3% of sampled farmers were willing to pay the seed and the value of mean willingness to pay from both double bounded dichotomous choice and open-ended questions was 26.89 and 32.67 birr per kilogram, respectively. The results of the bivariate probit model showed that sex, education level, extension contact, on-farm income, and credit have taken have a positive and significant effect, while off-farm income and initial starting bed have a negative and significant effect on the willingness of farmers to pay improved teff seed. Based on the findings government and other stakeholders need to focus on strengthening improved seed access through organized seed systems that comprehend all actors and promising cultivars through a well-established national extension and credit system to fill the current seed system gaps.

| Tea has a significant contribution to households’ cash income in the study area. However, decreasing productivity in the sector with price volatility led to a decline in output. Due to this fact, the studies were assessing the production trend with their bottlenecks, and identify the determinant of tea productivity and inefficiency through Cobb Douglas and stochastic frontier model. Data from a primary and secondary source of information were used from 135 tea out-growers. Based on the results, year 2017-018 has been used as production/base year. However, the productivity of tea in the 2020 production year is increased by 41.8% as the coverage of land for tea becomes increased by 53.6%. Lack of skill and knowledge (79.2%), lack of training and extension service 90.3%), low productivity (88.1%), the occurrence of pest and disease (80.7%), climate change (80.7%), weak market linkage (88.1%), monopoly market (69.2%, output price fluctuation (88.9%), and lack of centralized processing facilities (80.7%) were the key restraints on tea out-growers production and selling activity in the research area. The Cobb Douglas model indicated that labor force, fertilizer, land size, and improved seed all had an impact on tea productivity. While, technical inefficiency of tea production was determined by to level of education, the interaction of extension contact, distance to district market, harvesting time, training, and participation to off/non-farm income. So, improving the skill and knowledge of farmers through increasing extension service and training, on-time delivery of farm inputs, create market linkage, and improved tea nursery management were some of the suggestions made to alleviate the study areas’ tea production and marketing difficulties.

Climate change has adversely affected the livelihoods of people in Ethiopia since a large proportion of the population is heavily dependent on agriculture as their adaptive capacities are perceived to be below. Therefore, this study aimed to identify determinants of farmer adaptation strategies with their costs and benefits of each adaptation strategy. The data were collected from 155 farm households using a random sampling method through semistructured questionnaires. The result of the multivariate probit model revealed that the likelihood of farmers to adopt adjustment of planting date, changing crop varieties, intercropping, crop rotation, irrigation, and minimum tillage were 51.6%, 61.9%, 56.1%, 38.1%, 10.3%, and 27.1%, respectively. The joint likelihood of using all adaptation strategies was 4.2%, while their failure to adopt all the adaptation strategies was 9.8%. Among the given adaptation options, intercropping, adjusting planting dates, crop rotation, and changing crop varieties are economically viable climate adaptation strategies. Regarding the intensity of adaptation, 78% of sampled respondents were used more than one adaptation option, and their NPV and BCR were higher when they used at least one adaptation option. Farmers who did not adopt any adaptation options were able to receive the lowest income per unit production. The study recommends that households should use multiple combinations of adaptation practices rather than the use of a single adaptation option. Thus, the government and stakeholders must provide educational and extension service, training, and updated climate information to smallholder crop producers to use and select the best and combination of adaptation strategies.
