Perceptions and Adaptations to Climate Change in Southern Mali

Main Determinants ◽

This study aims to determine the impact of climate change on market garden production in the extreme south of Mali through the perception and adaptation of market gardeners to climatic phenomena. The study used two models, namely the probit selection and Heckman results models and multinomial logistic regression, based on data collected from producers. A total of 194 producers were surveyed. The results of Heckman's probit model indicate that experience in agriculture and the educational level of the producers are the two main determinants of producers' perception and simultaneous adaptation to climate change. Among these variables agricultural experience is both positively and negatively correlated with perception.

Abstract The impact of climate change on agricultural productivity is difficult to assess. However, determining the possible effects of climate change is an absolute necessity for planning by decision-makers. The aim of the study was the evaluation of the CSM-CROPGRO-Sunflower model of DSSAT4.7 and the assessment of impact of climate change on sunflower yield under future climate projections. For this purpose, a 2-year sunflower field experiment was conducted under semi-arid conditions in the Konya province of Turkey. Rainfed and irrigated treatments were used for model analysis. For the assessment of impact of climate change, three global climate models and two representative concentration pathways, i.e. 4.5 and 8.5 were selected. The evaluation of the model showed that the model was able to simulate yield reasonably well, with normalized root mean square error of 1.3% for the irrigated treatment and 17.7% for the rainfed treatment, a d-index of 0.98 and a modelling efficiency of 0.93 for the overall model performance. For the climate change scenarios, the model predicted that yield will decrease in a range of 2.9–39.6% under rainfed conditions and will increase in a range of 7.4–38.5% under irrigated conditions. Results suggest that temperature increases due to climate change will cause a shortening of plant growth cycles. Projection results also confirmed that increasing temperatures due to climate change will cause an increase in sunflower water requirements in the future. Thus, the results reveal the necessity to apply adequate water management strategies for adaptation to climate change for sunflower production.

The climate of Sri Lanka has been fluctuating at an alarming rate during the recent past. These changes are reported to have pronounced impacts on the livelihoods of the people in the country. Water is central to the sustainable functioning of ecosystems and wellbeing of mankind. It is evident that pronounced variations in the climate will negatively impact the availability and the quality of water resources. The ecosystem-based adaptation (EbA) approach has proved to be an effective strategy to address the impact of climate change on water resources in many parts of the world. The key aim of this paper is to elaborate the wide range of benefits received through implementation of EbAs in field level, watershed scale, and urban and coastal environments in the context of Sri Lanka. In addition, this paper discusses the benefits of utilizing EbA solutions over grey infrastructure-based solutions to address the issues related to water management. The wide range of benefits received through implementation of EbAs can be broadly classified into three categories: water supply regulation, water quality regulation, and moderation of extreme events. This paper recommends the utilization of EbAs over grey infrastructure-based solutions in adaptation to climate change in the water management sector for the developing region due its cost effectiveness, ecofriendliness, and multiple benefits received on long-term scales. The findings of this study will unequivocally contribute to filling existing knowledge and research gaps in the context of EbAs to future climate change in Sri Lanka. The suggestions and opinions of this study can be taken into account by decision makers and water resources planning agencies for future planning of actions related to climate change adaptation in Sri Lanka.

Survey research was conducted in Nawalparasi (B.S.W) district to assess farmers’ perception on climate change and the impact of climate change in wheat production. The survey was conducted in four municipalities (rural municipality). A total of 83 respondents were involved in this study. The primary data were collected through survey questionnaire, direct observation, focus group discussion, whereas secondary data on wheat area, production and productivity from different sources were also collected. The majority of the respondents (90.4%) perceived about climate change while 9.4% respondents were not aware about climate change. Furthermore, out of the respondents mentioning changes in temperature, rainfall duration, rainfall amount, dew and winter monsoon around 95.2%, 91.9%, 92.4%, 94% and 90.3% of them opinionated that there were changes in wheat production because of these factors respectively. Moreover, t-test and probit model analysis showed that there was great impact of climate change in wheat production and impact is increasing yearly in Nawalparsi(B.S.W) district. So, Government and policymakers should focus on climate resilient adaptation strategies formulation for crop cultivation through intensive research and extension packages. Adoption of technology to reduce the impact of climate change should be encouraged to gain optimum wheat production.

Abstract The paper investigates the impact of climate change adaptation on food security in the Semi-Arid parts of Kenya. Our research used a sample of 440 households, and an endogenous Switching regression is estimated to account for the heterogeneity in the decision to adapt or not, and for unobservable characteristics of pastoralists. We examined how pastoralists’ decision to adapt, that is to implement a set of strategies; storage/purchase of fodder, change in water management, partial shift to other livelihoods, banking livestock assets and herd management. The results demonstrate that climate change adaptation increases food security among pastoralists significantly. Pastoralists who have not adapted are seven percentage points more likely to be food secure if they had adapted to climate change while adopters are 27 percentage points likely to be food insecure if they had not adapted. The paper recommends the strengthening of policies on adaptation to climate change in the Semi-Arid lands where pastoralism is the primary means of livelihood. Although pastoralists have information on the effect of climate change on their livestock, incomplete information on the mechanism of adaptation remains a hurdle. Consistent climate change monitoring, timely warning systems and communication of pertinent information to pastoralists is fundamental.

The purpose of this work is to review and analyze the main results of modern research on the impact of climate change on the agro-sphere of Ukraine. Results. Analysis of research has shown that the effects of climate change on the agro-sphere are already being felt today and will continue in the future. The observed climate changes in recent decades have already significantly affected the shift in the northern direction of all agro-climatic zones of Europe, including Ukraine. From the point of view of productivity of the agro-sphere of Ukraine, climate change will have both positive and negative consequences. The positives include: improving the conditions of formation and reducing the harvesting time of crop yields; the possibility of effective introduction of late varieties (hybrids), which require more thermal resources; improving the conditions for overwintering crops; increase the efficiency of fertilizer application. Model estimates of the impact of climate change on wheat yields in Ukraine mainly indicate the positive effects of global warming on yields in the medium term, but with an increase in the average annual temperature by 2 ° C above normal, grain yields are expected to decrease. The negative consequences of the impact of climate change on the agrosphere include: increased drought during the growing season; acceleration of humus decomposition in soils; deterioration of soil moisture in the southern regions; deterioration of grain quality and failure to ensure full vernalization of grain; increase in the number of pests, the spread of pathogens of plants and weeds due to favorable conditions for their overwintering; increase in wind and water erosion of the soil caused by an increase in droughts and extreme rainfall; increasing risks of freezing of winter crops due to lack of stable snow cover. Conclusions. Resource-saving agricultural technologies are of particular importance in the context of climate change. They include technologies such as no-till, strip-till, ridge-till, which make it possible to partially store and accumulate mulch on the soil surface, reduce the speed of the surface layer of air and contribute to better preservation of moisture accumulated during the autumn-winter period. And in determining the most effective ways and mechanisms to reduce weather risks for Ukrainian farmers, it is necessary to take into account the world practice of climate-smart technologies.
