Wheat is considered to be a strategic crop for achieving food security. Wherefore, one of the current objectives today’s agriculture ensure consistent and sustainable yield this particular while mitigating its environmental footprint. However, along with genetic potential varieties, agricultural practices play key role in ensuring high stable wheat. Under changing climatic conditions, new eco-friendly were adopted wheat farming system recent decades. In review, large number peer-reviewed articles have been screened during last 15 years evaluate some environmentally friendly such as tillage system, biological protection, rotation, intercropping systems, integration resistant varieties yield. The present investigation unveiled that embracing methods holds engender yields, contingent upon normative strategy comprehensively addresses multiple factors. These include intrinsic attributes grown cultivars, plant nutritional parameters, soil agrochemical characteristics, specific conditions. Further in-depth investigations under field conditions are necessary help discernment appropriate techniques can efficaciously optimize different cultivated varieties.

Plant protection products (PPPs) are among the many drivers that lead to loss of biodiversity in agricultural landscapes and they a contributing factor global decline amphibians. The aim present study is estimate potential exposure amphibian population networks PPPs. Specifically, our goal describe spatial overlap with crops where PPPs potentially used. We terrestrial habitat suitability for eleven species using multi-scale distribution modelling approach. Using maps as basis estimating landscape resistance, we then calculate dispersal corridors between known breeding sites each species. Where available, use local genetic studies from literature validate select most appropriate resistance model By comparing locations suitable parcel-scale database on land-use, locate quantify hotspots PPP-exposure within core around species' along movement routes them. highlighting differences species, identify which particularly at risk gain insight into mechanisms habitats may influence these networks. Together, provide policy makers flexible tool can prioritize regions implementation locally adapted management strategies.
