Agriculture is a cornerstone of the economy, providing livelihoods for a significant portion of population. However, climate change significantly affects people, their lifestyles, and the ecosystems posing a critical challenge to the global community, particularly the underprivileged in developing nations. Recognizing the indispensable role of agriculture and the challenges posed by a changing climate, this paper emphasizes the paramount need for proactive adaptation strategies. Central to these strategies is the pivotal concept of Climate-Smart Agriculture (CSA), a multifaceted approach that encompasses a range of practices, including agroforestry, conservation agriculture, and the adoption of climate-resilient crop varieties. Delving deeper, the paper navigates through the farmer's perceptions, unraveling their understanding of climate change, and the complex barriers like social barriers, institutional limitations, financial barriers, and limited awareness that impede effective adaptation, and illuminates the instrumental roles that governmental bodies and institutions, and extension agents play in shaping and fostering climate-resilient practices. Collaboration between local communities, governments, and non-governmental organizations is essential to ensure the successful implementation of sustainable adaptation strategies. Embracing sustainable and forward-thinking approaches, particularly CSA, including agroforestry, conservation agriculture, water management techniques, climate-resilient crop varieties, ICT, and climate-smart pest management, the agricultural sector gains the potential to bolster its resilience against climate-induced disruptions, ensuring consistent agricultural output that contributes significantly to broader food security initiatives.

Climate Smart Agriculture (CSA) is a global strategy for enhancing food productivity amidst climate change uncertainties in the 21st century. CSA improves farmers’ incomes, reduces greenhouse emissions, and farming systems become resilient to climate change. Despite the vital role that CSA plays in the development of the agricultural industry and the economy, the extent to which CSA is related to sustainable agriculture (SA) is not well documented. Is CSA the same as SA? If they are the same, do CSA practices impose mitigation requirements for developing countries like Uganda? Studies or research on CSA and SA unfortunately have certain shortcomings. Lack of this knowledge makes it difficult to plan investments and develop policies that will increase farmers’ resilience to climate change and variability to improve SA. This study is aimed at assessing how CSA links to SA and whether the two contribute to climate change mitigation requirements. It was found that CSA and SA are also related in a way that the latter leads to lowering greenhouse gas emissions hence mitigating climate change. CSA and SA share a common principal goal of achieving food security. It was concluded that developing countries are the worst affected by the negative impacts of climate change and don’t have the adaptive capacity to respond to climate change effects.

Basin-based water management strategy is one of the necessary instruments for the protection and sustainable use of water resources against climate change. In this paper, the monthly precipitation distributions of the 25 major basins in Türkiye were produced, and amounts and volumes were computed and analyzed. Only annual modeling and assessments of precipitation may hide months with precipitation shortages. Empirical Bayesian Kriging (EBK), Ordinary Kriging (OK), and Inverse Distance Weighting (IDW) were implemented in interpolation. EBK outperformed in all months and calculations were based on the EBK. The month with the highest precipitation potential in Türkiye is December (77.9 mm, 60.77 billion m3), and the month with the lowest precipitation potential is August (13.8 mm, 10.76 billion m3). In the basins, the monthly precipitation amounts range between 2.7 mm and 185.2 mm, and the volumes range between 0.02 billion m3 and 13.24 billion m3. The basins with the highest precipitation depth were determined as the East Black Sea, Antalya, Asi, and Ceyhan, and the lowest as the Small Menderes, Konya, and Tigris-Euphrates in different months. The monthly precipitation patterns and potentials of the basins vary widely. In May, June, July, August, and September, when water, particularly agricultural irrigation, is required the most, the 20 basins, except for the 5 located in Northern Türkiye precipitation shortage was determined.

Frost events are of particular importance for plants. Its occurrence determines growing season. Early or late frost events may cause injuries and damage in plants which have not yet entered dormancy in fall/winter, and for plants in flowering period in winter/spring. Global average temperature increase has been accompanied by changes in extreme temperature events. Observations have shown that there has been a decreasing pattern in frequencies and intensities of frost events. In this sense, it is aimed in this study to analyse probabilities of frost occurrences within the latest 30-year climatic normal period, from the cold period of 1991-1992 to that of 2020-2021, at five locations (Aydın, Kuşadası, Nazilli, Söke ve Sultanhisar) in the province Aydın, western Türkiye. Six frost indices were selected, and three temperature thresholds to define frost were considered when daily minimum temperature (TMIN) being equal to or less than 0.0, -1.2 or -2.3°C.The selected frost indices are first fall frost (FFF), last spring frost (LSF), frost period (FP), number of frost days (NFD), dates of frost occurrences (DFO) and consecutive frost days (CFD). The results revealed that Nazilli and Sultanhisar are characterized by the highest probabilities of frost in terms of frequency, intensity and duration, along with the earliest occurrence of first fall frost and latest occurrences of last spring frost, and with longest duration of frost period. On the other hand, Kuşadası and Söke have opposite characteristics in comparison to Nazilli an Sultanhisar. Aydın lies in between them. The results are expected to provide information to schedule the agricultural activities, and to avoid detrimental impacts of frost events.

It is foreseen that there may be a water crisis in the next years due to global climate change, the need for food with the increasing population and the need for fresh water. Due to the scarcity of freshwater resources and the difficulty in access to quality water, water resources should be used in the most efficient way. Water conservation is of great importance in regions where water is scarce. The water harvesting method, which allows rainwater to be collected, stored and reused could be applied in various ways. In this study, water harvesting methods and techniques aiming to develop a strategy that will provide maximum benefit from rainwater in arid and semi-arid areas are discussed.

Nearly all of the apricot varieties grown in Malatya are dried apricots and the plantation areas in this region are expanding daily. Due to the impact of climate change, producers are growing apricots mostly under limited irrigation or even dry conditions. Therefore, it is essential to determine the drought resistance characteristics of the varieties commonly cultivated in this region. In this study, different irrigation levels of 100%, 75%, 50% and 25% of available water were applied to Hacıhalioğlu, Kabaaşı, Çataloğlu, Hasanbey and Soğancı apricot varieties. To evaluate the resistance of the varieties to drought stress and its relationship with physiological changes, chlorophyll a and b, carotenoids, total sugar, total starch and abscisic acid contents in the leaves were analyzed. A decrease in chlorophyll a and b, carotenoids, total starch values and an increase in total sugar and ABA values were determined due to the decrease in irrigation rates. In Kabaasi and Hasanbey varieties, which were observed as the most resistant to water shortage, chlorophyll a and b, carotenoids, total starch values were higher and total sugar content was lower at decreased irrigation levels. No difference was detected between varieties in ABA values. As a result of the observations in the drought resistance tests and physiological analyses, it was concluded that the most resistant varieties were Kabaasi and Hasanbey. Unfortunately, the most sensitive variety was the most widespread Hacihaliloglu. In addition, analyzing and evaluating the physiological changes occurring in apricot under drought stress will be useful in developing the most appropriate irrigation strategies for each variety and increasing water use efficiency. It may also be useful in cross-breeding studies to develop new drought-resistant varieties.

Sugar beet is one of the most economically important agricultural crops cultivated in many provinces of Turkey. Especially in recent years, there has been an increase in bacterial tuber rot due to factors related to climate change. In preliminary trials, soft rot disease by Pectobacterium caratovorum subsp. caratovorum (Pcc) and Pectobacterium betavasculorum (Pb) were detected predominantly in sugar beets in Central Anatolia. Today, some cultural measures and copper compounds are used against soft rot agents in sugar beet, but successful results cannot be obtained in preventing the disease. In this study, a total of 270 soil samples were taken from the rhizosphere of 10 different fields in 3 different periods in 3 different ecologically diverse districts (Çumra, Altınekin and Seydişehir) of Konya, one of the provinces with the highest amount of sugar beet production in Turkey. As a result of the isolations, a total of 3064 bacterial isolates were purified and 262 of them showed antibacterial activity against Pcc and Pb in vitro conditions. In addition, 15 antagonist bacteria with the highest inhibitory effect on the development of both pathogens were tested in greenhouse conditions, and according to the results obtained from here, 3 antagonists with the highest effect were tested in field conditions in the cultivation areas of 3 different districts named above. Biochemical, morphological and molecular diagnoses of antagonist bacteria with high efficacy were made. According to the results obtained, it has been concluded that rhizospheric bacteria with antagonistic effect have a success rate of 33-90% against Pcc and Pb pathogens, and that the biological products to be prepared in future studies can be used in ecological, climate friendly and within sustainable agricultural practices in sugar beet production areas.

Global climate change continues to leave irreversible effects worldwide. With the increase in the effects of climate change, especially in recent years, the amount of UV-B radiation reaching the earth's surface is also likely to increase. With increasing temperatures, the amount of precipitation in the world has decreased, and the drought has started to alarm. This study is tried to understand how plants can respond to these stresses using ash-leaf maple (Acer negundo L.) and sycamore maple (Acer pseudoplatanus L.) species. The effects of these stress factors on plant leaf morphology were investigated by applying certain intensities of drought (moderate [T2] and severe drought [T3]) and UV-B (8 kJ m-2 h-1 [T4] and 12 kJ m-2 h-1 [T5]) stresses on these two species with T1 (control) treatment. As a result, leaf width in A. pseudoplatanus species was at the lowest levels in individuals exposed to T3 and T9. In A. negundo species, leaflet length in T1, T2, T3, T4 T5, T6 (modarete+T4), T7 (modarete+T5), T8 (severe drought+T4), and T9 (severe drought+T5) treatment were 8.800, 8.704, 8.075, 8.792, 8.823, 8.516, 8.317, 7.993, and 8.605 cm, respectively. According to these values, it was observed that the leaflet length was the shortest in T8 (7.993 cm) treatment. On the other hand, the leaflet length in T9 was close to the T1 group. As a result, individuals exposed to T4 were more affected than T5 in applications applied to UV-B stress and T3. Therefore, the increase of UV-B radiation positively affects the plant's resistance to drought stress.

: Global climate change is a threat to Turkiye, especially in the agricultural sector. In recent years, the impact of climate change has been felt seriously in Çorum Province. The present study was carried out after it was observed that the average temperature in Çorum province, which was 10.8 °C in 1929-2019 period, rose up to 13.15 °C in 2020. The aim of the present study was to determine the factors that affect the climate change adaptation behavior of the farmers in Çorum, where 37% of the land is devoted to wheat production. A survey was conducted with 385 farmers in January and February, 2021. It was revealed that personal experience had a positive effect of 54% on adaptation behavior, 50% on risk perception and 81% on climate change beliefs. In addition, although belief in climate change had a 45% positive effect on risk perception, risk perception and beliefs had no significant effect on the adaptation behavior. As a result, raising the awareness of farmers about adaptation using agricultural extension services and personal experience teaching method before incurring economic loss is critical to reduce climate risks and to better adapt to climate change.

Global climate change is defined as a process that affects all living things and ecosystems globally and is claimed as the most critical problem of the current century. Turkey, which is shown as one of the most affected countries by this process, is among the “countries at risk.” It is stated that the temperature will increase throughout the country until 2100, and this increase may reach 6 ºC. In order to determine the possible effects of global climate change, it is necessary to predict how the climate structure and basic parameters may change. From this point of view, this study is aimed to determine the change of temperature and precipitation, climate types (according to De Martonne, Lang, and Emberger climate classification) which are the most critical climate parameters until 2050 and 2070 in Düzce, one of the important cities of our country. The current situation and possible changes in 2050 and 2070 have been compared using RCP 4.5 and RCP 8.5 scenarios. As a result of the study, the temperature, precipitation, and related climate types would change significantly throughout the province of Düzce, and this change will show itself as a significant temperature increase and change in precipitation regime. In addition, a shift in climate types towards continental climate types is predicted until 2070. In order to avoid the destructive effects of global climate change, it is recommended to take measures on a sectoral basis.
