Climate change is a recent challenge on crop production and productivity in the world. The objective of this paper is to review the major effects of climate change on the production and productivity of wheat in the high lands of Ethiopia. Effects of climate change on wheat would be mainly through changes in [CO2], temperature, rainfall, length of growing period, actual growth rate and increased evapo-transpiration, which may lead to reduce yield or complete crop failure. Moreover, flower fertilization and grain set are highly sensitive to heat stress during mid-anthesis. In C3 crops like wheat, the elevated CO2 level is expected to increase productivity as a result of higher CO2 diffusion through stomata leading to a higher photosynthesis rate. But, elevated [CO2] may have negative effects on the grain-quality of wheat in terms of protein, lipids, number of mitochondria and nitrogen contents. Unlike CO2, elevated temperature affects crop production negatively by increasing rate of respiration; hastening plant growth and development; increasing photorespiration of wheat, reducing photosynthetic efficiency due to O2 interrupts the photosynthetic path way instead of CO2, increasing rate of water loss by increasing evapo-transpiration and decreasing nutrient use-efficiency through increased rate of decomposition and mineralization. As a result, wheat area is forecast to be displaced by other crop types. In order to tackle this issue, major mitigation and adaptation measures for example promoting area closures and conservation agriculture-based (CA), agroforestry practices, efficient use of energy sources, etc. should be practiced and given special attention by the communities as well as the government to solve the effects of climate change on wheat production and productivity in the country.

As pointed out by Assessment Report 4 of IPCC, global climate change will increase the magnitude and frequency of water-related disasters such as flooding, surge and drought. In addition to this the social changes such as population problems in Japan will aggravate the vulnerability to the disasters. Two concepts to cope with the water-related disasters triggered by climate change are adaptation and mitigation. Though abatement of GHG gas emissions has been eagerly argued, Japan should be more concerned with and take the initiative both for mitigation and adaptation. As adaptation measures for water-related disasters, 3 measures are proposed in this paper; building disaster-awareness societies, building physical/social structures, and adaptation R&D. In addition to them, it is necessary to bring reconstruction of the national land into medium- and long term views as paradigm shift. In this paper, the following recommendations are proposed for the adaptation: the Japanese government should be aware of the importance of adaptation and strongly promote adaptation to mitigate water-related disasters, and the government should also cooperate in establishing adaptation in sustaining development of Asian monsoon areas and development programs.

Although Africa’s contribution to the world’s greenhouse gas emission is the smallest compared to other continents, yet they tend to be affected most by the variability in Climate. Malawi is not an exception to this climate change, as they are not just faced with rising temperatures and variable rainfall patterns, but with reoccurring droughts and severe flooding. Agriculture has been noted to contribute significantly to not only climate change but also has significant impacts on global warming through its greenhouse gas emissions. Nevertheless, not all farming systems impact negatively on climate change. Conservation Agriculture is a farming system that encourages no or minimum soil disturbance, maintenance of a permanent soil cover, and diversification of crop species. These three interlinked principles combined with good agricultural practices promote biodiversity and normal biotic processes, both on and under the ground surface, thereby increasing the productivity and nutrient use efficiency of water, into a more resilient farming system which will help sustain and improve agricultural production. This review looks at Conservation Agriculture practices in the Machinga Agricultural Development Division of Malawi and its role in climate change mitigation and adaptation. This paper shows that Conservation Agriculture has played an active role in the adaptation and mitigation of climate change effect by reducing atmospheric greenhouse gas emissions but suggested there is a need for the government to formulate a CA framework that is founded on the three interlinked principles and not just based on soil and water conservation principles which are currently being advocated and practised.

AbstractThis study investigated the perceived effects of climate change on crop production and household livelihoods of smallholder farmers in Mopani and Vhembe district, South Africa. Data was collected through a questionnaire administered to 150 smallholder farmers. The questionnaires were complemented by 8 focus group discussions and secondary data. Multinomial logit regression model was used to analyse the factors influencing smallholder farmers’ choice of climate change adaptation strategies. The study findings revealed that subsistence farmers perceived prolonged droughts (56.4%) as the main shock stressing crop production. Droughts often lead to low crop yield and high crop failure (73.3%). In response to the prevailing climatic conditions different gender adopted different strategies, 41% of female farmers adapted by changing planting dates, while male farmers employed crop variety and diversification (35%) and mixed cropping (15%). The smallholder farmers were vulnerable with limited adaptive capacity to withstand climate change due to compromised social, human, physical, natural and financial assets. The results showed that smallholder farmers tend to adapt better when they have access to extension officers (P<0.01). Therefore, it is important for the government to strengthen the relationship between smallholder farmers and extension officers for better climate change adaptation.

Mitigation And Adaptation

Abstract Climate change is an unavoidable phenomenon of natural and anthropogenic origin against which mitigation and adaptation are required to reduce the magnitude of impact and vulnerability, to avoid risk in vegetable farming and to ensure sustainable livelihoods of the agricultural community. Genetic improvement of vegetable crops is an appropriate adaptation strategy to cope with climate change adversities. A combination study of genomics and phenomics provides a clear understanding of the environment's effect on the transformation of a genotype into phenotype. Grafting of a susceptible scion cultivar onto a resistant rootstock is another way of utilising plant biodiversity against climate change. Agronomic practices such as resource conservation technologies, mulching, organic farming, carbon sequestration by cropping systems and agroforestry provide a suite of possible strategies for addressing the impacts of climate change on vegetable production. Protected cultivation and post-harvest technology can be significant practices in facing the challenges of climate change. Weather forecasting models and growth simulation models can be used to predict the possible impact of climate change on vegetable crop production and they also help in framing necessary adaptation measures.

Abstract There are two general pathways towards climate change litigation in China: tort-based litigation to hold carbon emitters accountable in civil law, and administrative litigation against the government to demand better climate regulation. While the first pathway is gaining momentum among Chinese scholars, this article argues that legal barriers to applying tort-based rules to climate change should be fairly acknowledged. The article argues that China's legal framework for environmental impact assessment (EIA) provides more openness and flexibility for the resolution of climate change disputes. Therefore, EIA-based climate lawsuits, which challenge environmental authorities for not adequately taking climate change factors into account in decision-making processes, encounter relatively fewer legal barriers, require less radical legal or institutional reform, and have greater potential to maintain existing legal orders. The regulatory effects produced by EIA-based litigation suggest that the scholarship on climate change litigation in China should take such litigation seriously because it could influence both governments and emitters in undertaking more proactive efforts. This China-based study, with a special focus on judicial practice in the largest developing country, will shine a light on China's contribution to transnational climate litigation.

As users of forest products and guardians of traditional knowledge, women have always been involved in forestry. Nevertheless, their access to forest resources and benefits and participation in forest management is limited compared to mens despite the fact that trees are more important to women, who depend on them for their families food security, income generation and cooking fuel. This guide aims to facilitate the incorporation of a gender lens in climate change mitigation and adaptation operations in forests, with special attention to those framed in REDD. This guide addresses four themes value chains, environmental payment schemes, firewood and biodiversity that relate directly to 1) how climate change impacts affect women in the forest and 2) how mitigation and adaptation measures affect womens access to resources and benefits distribution.

Abstract Global climate change is one of the main threats facing humanity and the impacts on natural systems as well as humans are expected to be severe. People can take action against these threats through two approaches: mitigation and adaptation. However, mitigations and adaptations are contingent on the level of motivation and awareness, as well as socio-economic and environmental conditions. This study examined personal perception and motivation to mitigate and adapt to climate change among the university students in the capital city of Pakistan. We divided the respondents into social sciences, applied sciences and natural sciences, using logistic regression analysis. The results indicated that students who perceive severity, benefits from preparation, and have more information about climate change were 1.57, 4.98 and 1.63 times more likely to take mitigation and 1.47, 1.14 and 1.17 times more likely to take adaptation measures, respectively. Students who perceived self-efficacy, obstacles to protect from the negative consequences of climate change and who belonged to affluent families were more likely to take mitigation measures and less likely to take adaptation strategies. However, mitigation and adaptation were unaffected by age, gender and study discipline.

AbstractBrazil is the second largest forested country in the world with a high level of naturalness and biodiversity richness, playing a significant role in the adoption of mitigation and adaptation strategies to climate change. Although the Brazilian federal government is mainly responsible for the protection of natural ecosystems, the decentralization process, which demands competences of the states and municipalities, allowed the establishment of several agencies and institutions dealing with monitoring, assessment, and management of forest ecosystems through a complex and interrelated number of forest policies. Nevertheless, the deforestation rate, with a consequent loss of biodiversity and ecosystem services, represents critical challenges, attracting worldwide attention. The variety of mitigation and adaptation measures adopted over the years represents viable tools to face climate change and to promote climate-smart forestry in Brazil. Notwithstanding the positive effects achieved in the last decade, a better coordination and practical implementation of climate-smart forestry strategies is required to reach nationally and internationally agreed objectives.This chapter aims to depict the Brazilian forestry sector, highlighting the management strategies adopted overtime to counteract climate change.
