“…They recommended taking into account both the height and optical porosity. Kučera et al [27] concluded that the optical porosity best reflects the effect of one-row windbreaks. In the case of wider windbreaks, parameters for expressing the 3D structure should be developed.…”

Linear elements in the agricultural landscape, particularly windbreaks, reduce the wind speed and improve the microclimate in the protected zone. They offer many direct effects on agricultural production with maximum benefits of ecosystem biodiversity. Despite the indisputable advantages and favourable effects of permanent linear vegetation elements, their representation in the agricultural landscape is not as frequent as it used to be. Moreover, the formerly planted elements do not fulfil their original function due to the overgrowth and neglected maintenance. The optimum spatial and functional organisation of the newly proposed linear elements requires evaluation of the existing linear vegetation, its functional parameters and involvement in the landscape ecological network. Our report presents methods for the evaluation of the linear elements, both from the aspect of their internal structure and species composition (category A) and their involvement in the functional system (category B). The evaluation is based on seven established criteria and results in a point scoring system that reflects the characteristics of the reference criteria. In five selected localities, we tested the linear elements as individuals by the A method and their integrity by the B method of evaluation. In one locality only, the state of windbreaks was assessed as functional; at two localities, they were found as conditionally functional, and at two other localities, the state of the windbreaks was assessed as non-functional. An example of the evaluation of individual windbreaks (category A) is demonstrated in model localities in South Moravia, Czech Republic. The results of the evaluation of the model localities thus point out an unsatisfactory state of the linear elements in the region of South Moravia and the need to accord them increased care and to establish new plantations under professional supervision. Their building can be sped up by using the tools of land consolidation.

“…According to Kucera et al, [19] and Reháek et al [20] found that windbreaks could effectively protect against wind erosion, especially when agricultural plants do not cover the soil. Within the agricultural landscape, windbreaks and other linear constructions reduce wind speed and improve the microclimate within the sheltered zone.…”

Nowadays, climate variability and changes are among the main environmental challenge within the world. The negative implication of global climate change on the agricultural sector is unequivocal, as its consequences affect the livelihoods of particularly smallholder farmers within the tropics. Windbreaks agroforestry practices has been offered as a climate smart agriculture technologies or practices to reduce the global climate variability and climate change. It is one of the most important adaptation and mitigation strategies of climate change. This review paper focuses on the importance of windbreaks agroforestry practices in global climate change adaptation and mitigation, the role of windbreak technology at the farm and landscape levels, effects of windbreaks on reduction wind speed and soil protection, role of windbreaks to reduce the vulnerability of climate change. Windbreaks can improve the efficiency of ecological and ecosystem services provided by natural resource. If planned properly, nitrogen-fixing trees also can provide direct benefits for increasing the productivity of agricultural crops in an organic way and by resulting higher yields. They enhance animal health, feed efficiency, reduce smells, and increase producers' economic returns when utilized in livestock production systems. Windbreaks can help boost crop productivity, diversify goods, and lift farm revenue by improving soil quality and reducing erosion, improving water quality and reducing flooding damage, improving animal habitat and biodiversity, and lowering pest control inputs. Within the final section, the precise challenges to adapting windbreaks agroforestry practices and adoption mechanisms were reviewed. Windbreaks agroforestry systems may prove to be very useful component of agricultural adaptation as both an economically feasible adaptation strategy for smallholder farmers vulnerable to climate change as well as a profitable greenhouse gas mitigation opportunity.

“…Agroforestry systems can improve the soil health of arable systems, as the trees can increase soil organic matter and retain nutrients (Jose et al, 2009). Integrating trees in crop systems can also reduce soil erosion by increasing the permanence of vegetation cover (Jose et al, 2009) and windbreaks and shelterbelts can reduce windspeed (Bartus et al, 2017;Kučera et al, 2020). Trees on arable land can increase rainfall infiltration rates and soil water retention and reduce nitrate leaching (Siriri et al, 2013).…”

Agroforestry integrates woody vegetation with crop and/or livestock production to benefit from the ecological and economic interactions. The objective of this paper is to systematically determine the spatial distribution of agroforestry in the EU, and changes in the areas and types of agroforestry from 2009 to 2018. This was achieved using the Land Use/Cover Area Statistical (LUCAS) dataset. Agroforestry was categorised into silvopastoral, silvoarable, agrosilvopastoral, grazed permanent crops, intercropped permanent crops and kitchen gardens systems. In our categorisation of ‘agroforestry’, sites combing trees and shrubs with understorey grass or forage were required to show evidence of grazing. In 2018, the total area of agroforestry in the EU28 was 114,621 km2 equivalent to 6.4% of the utilised agricultural area (UAA), and a majority located in the Mediterranean bioregion. Silvopastoral was the most widespread system, representing 81% of the total agroforestry area (5% of UAA), with almost a third of that area present in Spain. An initial analysis of the LUCAS data suggested that the area of agroforestry increased from 2009 to 2012, before declining from 2012 to 2018. However our subsequent analysis suggests that the area of agroforestry in 2009 was underestimated due to a mis-categorisation of some grazing areas. After making corrections, we calculated that the area of agroforestry (using the above definitions) in the EU23 (a full-time sequence for the EU28 is unavailable) declined by 47% between 2009 and 2018. This decline is primarily due to a reduction in outdoor grazing, perhaps driven by reduced livestock numbers and/or permanent livestock housing. The only agroforestry system showing an increase was kitchen gardens (7%). The paper highlights the usefulness of the LUCAS dataset for studying the extent of agroforestry in Europe, but also potential limitations in terms of the consistency of the location of data points and the categorisation of grazing. The paper also argues that although the area of within-field agroforestry may be declining, the drive towards net zero greenhouse gas emissions may be re-establishing the link between increased tree cover and food production at a farm-level.
