Global climate change poses a significant threat to sustainable development. This is evident through rising temperatures and resulting phenomena such as glacier melting, extreme weather events, and agriculture challenges. This impact extends across ecological, social, and economic systems worldwide. Agriculture, in particular, faces significant risks, with traditional crop production becoming increasingly untenable. This study, based on fieldwork in Tajikistan, conducted by Fairtrade NAPP, on one hand traces the current agriculture practices in Tajikistan that contributes to the greenhouse gas emission. On the other, it attempts to estimate GHG emission through these agricultural practices and compares the different methods for greenhouse gas emission. It relies on quantitative method and an online tool, Cool Farm Tool to estimate the emissions of Green House Gas in agriculture practices of crops like cotton, apricots and vegetables. In connection to this, the study identifies the causes of greenhouse gas emissions and the carbon sinks, and thereby draws attention to the sustainable agricultural practices.
