  2. Effect of Climate Variables on Yield and Yield Variability of Rice in Different Agro-ecological Regions of Nepal: A Panel Data Analysis, JOSHI, Niraj Prakash PIYA, Luni, JOSHI, Niraj Prakash PIYA, Luni, Conference on Agriculture and Climate Change, 2017/03/27, Without Invitation, English, Elsevier, Melia Sitges, Sitges, Climate change is expected to impact food security in Nepal through its adverse impact on agriculture, which is predominantly subsistence. Considering the importance of rice in food habit of Nepali, thereby food security, this paper makes an empirical analysis of climate variables’ impact on yield and yield variability of rice in different regions of Nepal. The data of climate variables on monthly basis, namely minimum temperature, maximum temperature and precipitation from 1978 to 2013 were obtained from Department of Hydrology and Meteorology. Multiple regression analysis method, considering the five nearest meteorological stations, is adopted to estimate missing data. Empirical Bayesian Kriging technique was employed to interpolate the climate data using ArcGIS10.4.1 for 15 regions, which were divided based on existing agro-ecological and administrative division. The data on rice production attributes such as production, area and yield was compiled from different volumes of ‘Statistical Information on Nepalese Agriculture’. The panel data on climate variables; and rice production attributes were prepared for data analysis. The impact was assessed using a stochastic production function approach suggested by Just & Pope (1978) for panel data. Increased rice yield and area has contributed in increased production. However, rice yield in some regions is dwindling. Climate trends have significant influence on rice yield and yield variance in various magnitude and direction in different regions. Empirical evidences show the adverse effect of increasing temperature on rice yield in Tarai. Measures to cope with the increasing temperature is important in entire Tarai. Similarly, given the limited irrigation coverage, rainfall is still significant determinant of rice yield. However, its higher interannual variability has adversely affected rice yield. Regulation of water through development of proper infrastructures would help to adapt the higher interannual variability of rainfall, which is expected to become more intense due to anticipated change in climate.

  4. Prospect of organic agriculture in achieving food security in Least Developed Countries, JOSHI, Niraj Prakash PIYA, Luni MAHARJAN, Keshav Lall, JOSHI, Niraj Prakash PIYA, Luni MAHARJAN, Keshav Lall, 2nd Annual International Conference on Poverty and Sustainable Development, 2015/12/15, Without Invitation, English, The International Institute of Knowledge Management, Colombo, Sri Lanka, Hotel Galadari, Colombo, Sri Lanka, This paper aims to analyze prospects of Organic agriculture (OA) in achieving food security goal of Least Developed Countries (LDCs). FAOSTAT data on food balance and literature are the main source of data. Yield ratios of crops show higher yield from OA compared to conventional agriculture in LDCs. Food supply is growing at higher rate in LDCs than Northern America between 1961 and 2011. However, growth rate in nutrient supply in LDCs is meager. Hence, current food supply in the region is not able to supply the standard nutrient requirement. Cereal is the single most important food items contributing to nutrient supply in LDCs indicating lack of nutrient diversity. Under such context OA would increase food supply of all food categories. Consequently, LDCs can achieve the standard nutrient requirement and help in dealing with persistent undernourishment in LDCs. However, concerted effort is necessary for wider acceptability of OA in LDCs. Besides, the possible challenges brought by wider adoption of OA such as increased demand for organic inputs should not be overlooked while formulating policy to expand OA in LDCs
