“…However, this adaptation in the choice of varieties planted and in management is likely also to contribute to generally lower yields. A study by Olesen et al (2011) seems to support this argument, showing that in Finland, a small yield increase has occurred during the last 10−20 yr that is partly linked to increasing temperatures, which has allowed earlier sowing and a prolonged growing season (Rötter et al 2013, Peltonen-Sainio & Jauhiainen 2014, Palosuo et al 2015. On the other hand, the wheat yields in Greece have been declining, which is likely also linked to the increase in temperatures.…”

“…The stagnating wheat (and barley) yields across European regions (as depicted in Fig. 3) have been found to be co-determined by the warming climate (Brisson et al 2010) and/or by changes in management, especially in the changes to fertilization application due to environmental regulations (Finger 2010, Palosuo et al 2015. Gömann et al (2015) reported that wheat crops have been extended to less favorable sites during the last decades in Germany.…”

Europe is, after Asia, the second largest producer of wheat in the world, and provides the largest share of barley. Wheat (and to a similar extent, barley) production in Europe increased by more than 6-fold during the 20th century. During the first half of the 20th century, this was driven by expanding the harvested area. This was followed, from the mid-20th century, by a massive increase in productivity that in many regions has stalled since 2000. However, it remains unclear what role climatic factors have played in these changes. Understanding the net impact of climatic trends over the past century would also aid in our understanding of the potential impact of future climate changes and in assessments of the potential for adaptation across Europe. In this study, we compiled information from several sources on winter wheat and spring barley yields and climatological data from 12 countries/regions covering the period from 1901−2012. The studied area includes the majority of climatic regions in which wheat and barley are grown (from central Italy to Finland). We hypothesized that changes in climatic conditions have led to measurable shifts in climate−yield relationships over the past 112 yr, and that presently grown wheat and barley show a more pronounced response to adverse weather conditions compared to crops from the early 20 th century. The results confirm that climate−yield relationships have changed significantly over the period studied, and that in some regions, different predictors have had a greater effect on yields in recent times (between 1991 and 2012) than in previous decades. It is likely that changes in the climate−yield relationship at the local level might be more pronounced than those across the relatively large regions used in this study, as the latter represents aggregations of yields from various agroclimatic and pedoclimatic conditions that may show opposing trends.

“…Our understanding on climate impacts and adaptations of crop growth and productivity can be accelerated by analyzing historical experiences over the past few decades (Tao et al, 2012a,b;Palosuo et al, 2015). Along this line, recently, an increasing number of studies have investigated climate impacts on crop yields in a range of regions of the world using statistical models and long-term historical datasets of crop and climate (e.g., You et al, 2009;Reidsma et al, 2009;Welch et al, 2010;Lobell et al, 2011a;Tao et al, 2012b;Ray et al, 2015).…”

“…Historical crop trial data, with accurate records of phenology, yield, weather, as well as cultivars and management practices, allow one to study how weather affects crop yield in a setting in which known agronomic management practices are taken based on actual weather (Welch et al, 2010;Lobell et al, 2011b;Tao et al, 2012a;Palosuo et al, 2015). Such diagnostic studies are more robust in understanding impact and adaptation mechanisms, improving crop models, and consequently have important implications for predicting the impact of future climate change on agricultural production (Welch et al, 2010;Lobell et al, 2011b;Tao et al, 2012a).…”

Our understanding of climate impacts and adaptations on crop growth and productivity can be accelerated by analyzing historical data over the past few decades. We used crop trial and climate data from 1981 to 2009 at 34 national agro-meteorological stations in the Huang-Huai-Hai Plain (HHHP) of China to investigate the impacts of climate factors during different growth stages on the growth and yields of winter wheat, accounting for the adaptations such as shifts in sowing dates, cultivars, and agronomic management. Maximum (T max) and minimum temperature (T min) during the growth period of winter wheat increased significantly, by 0.4 and 0.6 • C/decade, respectively, from 1981 to 2009, while solar radiation decreased significantly by 0.2 MJ/m 2 /day and precipitation did not change significantly. The trends in climate shifted wheat phenology significantly at 21 stations and affected wheat yields significantly at five stations. The impacts of T max and T min differed in different growth stages of winter wheat. Across the stations, during 1981-2009, wheat yields increased on average by 14.5% with increasing trends in T min over the whole growth period, which reduced frost damage, however, decreased by 3.0% with the decreasing trends in solar radiation. Trends in T max and precipitation had comparatively smaller impacts on wheat yields. From 1981 to 2009, climate trends were associated with a ≤ 30% (or ≤1.0% per year) wheat yield increase at 23 stations in eastern and southern parts of HHHP; however with a ≤ 30% (or ≤1.0% per year) reduction at 11 other stations, mainly in western part of HHHP. We also found that wheat reproductive growth duration increased due to shifts in cultivars and flowering date, and the duration was significantly and positively correlated with wheat yield. This study highlights the different impacts of T max and T min in different growth stages of winter wheat, as well as the importance of management (e.g. shift of sowing date) and cultivars shift in adapting to climate change in the major wheat production region.

“…This can be accomplished by reducing the gaps between farmers' actual crop yields and such yields that would be possible if optimal management were adopted, the so-called 'yield gap' (Yg, Van Ittersum et al, 2013). Assessment of the scope for narrowing these gaps relies on a robust reference database on yield gaps and their underlying causes (Van Bussel et al, 2015;Palosuo et al, 2015). Over the last two decades a number of different methods for yield gap analysis have been developed (see, e.g.…”

It has been established that agriculture is the backbone of Cameroon's economy, where 80% of the labor force is engaged in the agricultural sector and provides 22.3% of gross domestic product and 30% of its export revenues. The investigated branch forms the commodity supply of agricultural products both on the domestic and foreign markets, the following types of products: cocoa, coffee, cotton, bananas, palm oil, tobacco, tea, pineapple, corn, millet, sorghum, yams, potatoes, beans and rice. It has been determined that the livestock sector has been developed throughout the country and plays an especially important role in the northern region of the country. It has been proved that the main goal of the country's agricultural development is to ensure food security, whose achievement is strongly influenced by globalization of climate change. For the country under study, the country's orientation towards a "product concept" is characteristic, in which the main objective is to ensure the physical and economic availability of agricultural food. The strategic priorities in the country's agricultural development, which include the mobilization of local resources for intensive production taking into account environmental requirements, are highlighted. It is substantiated that today specialized regions have been formed in relation to the production of certain types of products, which allowed to increase the productivity of agricultural crops. It is noted that there are differences in indicators of productivity of agricultural production in farms and research stations, which proves the existence of unused reserves for improving production efficiency. The characteristic features of development of agricultural production of the country are systematized: low level of technical support; a manifestation of the tendency to increase the land of farms; the prevalence of small commodity producers; low income farmers; predominance of informal economic relations; use of manual labor; complicated access to loan financing sources; low level of involvement of commodity producers in value added chains. It is proved that under conditions of intensification of investment activity in the country's agriculture and realization of the foreseen measures of the strategic national plan, conditions and preconditions for effective development, modernization of production infrastructure, access of farmers to sources of financing and other components of sustainable development will be formed. It is highlighted that one of the conditions for the sustainable development of agriculture in the country is the intensification of agricultural production, which will promote ecological and social sustainability. Important instruments for its achievement are technological innovations in the direction of introducing new or improved agro technology of cultivation and modern management practices, new breeds of farm animals and poultry, integrated practices for improving soil fertility and widespread replacement of manual labor. Innovative solutions need to be coordinated with the specifics of the production process, and in terms of environmental and water and energy intensity. Key words: agriculture, food safety, farmer, innovation, investment attractiveness.
