THE SMALL EARTH NEPAL

Together We Stand for Sustainable Lifestyles

Our Research

SEN works in multidisciplinary research projects particularly focusing to environmental change sectors. Our research interest are in climate change, hydrology, agriculture and livestock sectors and making the climate, weather and water information available to the end users for adjusting lifestyles according to the changing climatic conditions. We have a team of researchers as staff and fellow scientists from multidisciplinary sectors such as climate science, hydrology, vulnerability assessment, climate modeling, snow and glacier modeling, agronomy, livestock services and livelihood. Our working beauty is to engage graduate students from universities across Nepal in our research projects along with their academic advisors.

 

Some of the research projects we have been carrying out in Nepal and the Himalayan regions are as below:

Runoff Scenario and Water Based Adaptation Strategies in South Asia

The project aims to understand the climate and changing climate of the region with particular focus on water resources and its consequences to people and society. Observed hydro-meteorological data and IPCC climate scenarios will be used for runoff simulation and development of future water scenarios using distributed/physical-based hydrological models. Snow statistics will be calculated from MODIS daily product using MODIS (Moderate Resolution Imaging Spectro-radiometer) Snow Tool and MRT (MODIS Re-projection Tool). Community based adaptation strategies will be developed based on the model outcomes, which will facilitate the countries for informed decision making process.

An Assessment of Economic Loss due to the 2013 Flood of Mahakali River in relation to Climate Change

The primary goal of this proposed research is to come up with an outcome or a model that provides a tangible input to the national policy formulation in the process of mainstreaming climate change risk management in development. The second goal is to add more information to the existing wealth of knowledge regarding economic aspect of the losses due to water-induced disasters, also considering the climate change impact.

Adaptation for Climate Change by Livestock Smallholders in Gandaki River Basin in Nepal Himalaya

Major objective of the project is to analyze local and regional climate change and focus on the frequency of hydro-meteorological extremes over the past few decades to gauge the impact of climate change on smallholders’ livestock health and productivity. This project will downscale climate variability over the GRB to much higher resolution (1-10 km) than has been done until now. The results of this analysis will provide a better understanding of how climate change is impacting the economies and ecosystems that are essential to the livelihood of livestock keepers in Nepal.

Building Climate Resilience in Farming Systems in Sloping Lands of South Asia

The project will build on successful farming models reported from other Asian countries, e.g. Conservation Farming Villages (CFVs; Cruz et al. 2014), and address this key policy question and support informed-decision making, by providing the much needed scientifically validated information on resource degradation and environmental sustainability, best practice FS for higher level resilience, and well-being of farming communities in sloping lands, while ensuring food and nutrition security of farm households and at national and regional levels. The main objective of the research project is to assess resilience and characterization of diverse FS in hilly areas SA based on their adaptation capacities, with special emphasis on food and nutrition security.

Developing Climate Inclusive Potential Loss and Damage Assessment Methodology for Flood Hazards

Flood events have been more intense and frequent in most of the Asian countries in the recent decades creating hardship to ecosystems and livelihoods. Therefore, estimation of loss and damage due to impending flood event is of an utmost importance to take proactive measures to minimize flood disaster risks through climate smart Disaster Risk Reduction (DRR) and Climate Change Adaptation (CCA) interventions.

A Hydro-microbiological approach for water security in Kathmandu Valley

This project includes comprehensive aspects of water including development of water security maps of core areas of Katmandu valley and its peripheral areas, which have limited energy and water resources. Divided into five components, the projects plans to study the qualitative, quantitative, microbial, health and social aspect of both groundwater and surface water of the valley.

Assessing the economic impact of climate change on agriculture, water resources and food security and adaptation measures using seasonal and medium range of forecast

Climate change is a growing food security concern for countries in the Ganges-Brahmaputra Meghna (GBM) basin; it is expected to have a direct impact on crop yield as a result of changes in temperature, precipitation, and carbon dioxide (CO2) concentration. Research is needed to identify the scale and distribution of the potential impacts and possible adaptation strategies to support policy development. This paper presents the results of a hydrological simulation of the components of water balance in the GBM basin in the 2050s under different climate scenarios. The impact on the yield of major crops in two representative districts in Bangladesh and Nepal was assessed using the Decision Support System for Agro-technology Transfer (DSSAT) tool with projections for future seasonal water availability, temperature, and CO2 concentration. The results indicate that the predominance of the monsoon season in water availability will increase by the 2050s, that there will be more frequent flood events of higher magnitude, and that groundwater recharge will increase. The change in surface water availability will be more pronounced during the pre-monsoon season in Nachole, Bangladesh and during the dry season in Rasuwa, Nepal. In Nachole, yield of monsoon season rice is projected to increase and of dry season rice to decrease; maize yield in Rasuwa, Nepal is projected to decrease. Three adaptation options were tested for reducing yield loss and addressing water stress issues. The results are discussed with a view to suggesting agricultural adaptation options and supporting formulation of water resources policy.
