Abstract: Biodiversity conservation in current era of increasing global climate change and rapid land degradation is a major challenge globally. Agroforestry is an important land use system addressing biodiversity conservation and enhancing social and environmental goals. However, there is scarcity of empirical evidence on contributions of agroforestry for conservation of biodiversity and reduction of CO2 emission. This paper aimed to provide empirical information on the role of agroforestry for conservation of flora and fauna biodiversity and climate change mitigation and adaptation. The result revealed agroforestry has contributed huge role in conservation of fauna and flora diversity and mitigation of CO2 than open cereal based agriculture. Trees in agroforestry are the important component in conservation and mitigation of climate change effects. Binding CO2 through biomass and soil, reducing other causes for CO2 emission such as deforestation and microclimate modification are major climate change mitigation actions. Provision of numerous other ecosystem services to people and their agroecosystem such as provisioning services (shelter, food, fodder, etc.), regulating services (pest and diseases control, modification of microclimate, reducing wind effect, etc.) and supporting services (nutrient cycling) help them build the resilience towards changing climate effects. Hence, responsible bodies must consider the huge potential of agroforestry in their conservation and climate change mitigation and adaption strategy.

Abstract: The cadmium is one of the metallic element traces very toxic for vegetables, animals and human. Its presence in the soil is aggravated by the various cultural practices. This study is to test the effect of cadmium on the physiological parameters and its accumulation in two varieties of bread wheat (Triticum aestivum L). The relative growth of seedlings, the rate of chlorophyll a and b, the proline, soluble sugars and rate of accumulation of Cadmium are measured under four concentrations of Cd staggered from 0 to 150mg/l and tested on the varieties Arz and Hiddab. Results show an important reduction of the relative growth of the seedlings of both varieties but in a different way. A disturbance of the various physiological processes is observed a decrease of the photosynthesis gradually with the increase of the dose in cadmium on the chlorophyll a and b compared with the control, increase of the rates of the proline, the soluble sugars and the rate of cadmium in seedlings following the increase in concentration of the metal study. The Arz variety is more accumulating than Hiddab. The presence of the cadmium in the environment causes a physiological disturbance of the processes and affects dramatically the production of the biomass.
