Potential suitable habitat of Buckwheat (Fagopyrum spp) under the climate change scenarios in Nepal
Dol Raj Luitel,Siwakoti Mohan,Mohan D. Joshi,Rangaswami Muniappan,Pramod K. Jha 한국작물학회 2021 Journal of crop science and biotechnology Vol.24 No.4
Buckwheat is minor crop of Nepal. Due to their multiple uses, short growing periods, high nutritional and medicinal values, wide adaptability has become popular not only to researcher but also for farmers and consumers globally. It grows in a wider range from low land Terai to higher mountains of Nepal. Maxent modelling was used to quantify the current suitable habitat and predicted future suitable area under diferent climate change scenarios, based on representative concentration pathways (RCP 4.5 and 8.5) in two diferent time periods (2050 and 2070 AD) using climatic predictive variables and species localities. The most suitable habitat area of cultivation, area loss, and gained for buckwheat were determined. The model showed that about 46% area of country is climatically suitable for buckwheat within the elevation range of 289–4441 m. Habitat suitability of buckwheat would shrink by 7.5% and 8.2% under RCPs 4.5 and by 7.6% and 8.3% under 8.5 RCPs in the year 2050 and 2070, respectively. The loss and gain area analysis also indicated that suitable area would be lost more than gained in both 2050 and 2070. These fndings are expected to support planning and policy framing for climatic resilience smart agriculture practice to meet the livelihood and food security problems in the mountains of Nepal. Due to medicinal value of buckwheat, its demands is increasing. The increasing demend of buckwheat would be fulflled by increasing production under climatically suitable area under climate change scenarios.

Background: Parthenium hysterophorus is a noxious invasive weed in tropical and subtropical regions of the world, including Nepal. Among 11 species of biological control agents released to control P. hysterophorus in Ausrtalia, winter rust Puccina abrupta var. partheniicola arrived fortuitously and has established in Kathmandu Valley, Nepal, nearly a decade back. However, the prevalence and effectiveness of this rust as a biological control agent in Kathmandu remain unknown. To address this knowledge gap, a roadside survey was done at an interval of 2 ± 0.25 km in Kathmandu Valley to assess the P. abrupta var. partheniicola incidence and its impacts on P. hysterophorus. Infested individuals of P. hysterophorus were further divided into four severity classes (very low, low, medium, and high), and rust incidence was calculated. The impact of the winter rust on the growth of P. hysterophorus was assessed by comparing biomass and seed output of infested and non-infested individuals. Results: Among 81 locations where P. hysterophorus was present in the Kathmandu Valley, winter rust infestation was observed at 98% locations. At some locations within Kathmandu Valley such as Tinkune, Kirtipur, Chabahil, Buddha Chowk, and Dhobighat, the impacts of the rust on P. hysterophorus were medium to high. Aboveground biomass and seed output of P. hysterophorus were reduced by 47% and 73%, respectively, due to winter rust infestation. The study indicates that winter rust incidence is widespread in Kathmandu Valley with very low to high levels of damages to P. hysterophorus depending on the localities. Conclusion: The rust has, therefore, a potential to reduce the growth performance of P. hysterophorus, and it can be used as a component of integrated management of P. hysterophorus by introducing to other suitable areas in Nepal.
