“…The results indicate that conservation increases water flow, and the value generated from additional water flow is enough to improve the livelihoods of the upstream communities. The land use determines the vegetation and the vegetation reduces water movement, intercepts the water, and returns a portion of it to the atmosphere through evapotranspiration (Hamilton, 1987).…”

International audienceAgainst a backdrop of environmental crisis, attributed to the impact of tourism and the practices of rural populations, Nepal has created protected areas with a view to preserving the Himalayan environment and promoting sustainable tourism in the regions concerned. Given the conflicts between conservation needs and development needs, local communities are now being given a bigger role in the governance of these protected areas. Yet the measures being taken simply accompany and guide well-established tourism dynamics that operate on a much greater scale. Trekking is thus a tourism system largely in the hands of the country's mountain communities and is an activity that has enabled these communities to improve their living conditions while at the same time limiting environmental impacts. In this sense it is very much in line with the principles of sustainable development.Le développement du trekking au Népal a suscité des inquiétudes qui ont abouti à la création d'aires protégées sur la foi d'un scénario de crise environnementale dont les touristes et les paysans étaient jugés responsables. Devant les conflits entre la conservation et les nécessités de développement des régions concernées, la gouvernance des aires protégées a évolué dans le sens d'une meilleure prise en compte des sociétés locales. Pour autant les mesures prises ne font qu'accompagner et diriger des dynamiques touristiques plus anciennes qui s'exercent à des échelles plus vastes. Le trekking constitue ainsi un système touristique très largement aux mains des sociétés montagnardes du pays qui a permis l'amélioration de leurs conditions de vie tout en limitant ses impacts environnementaux. En ce sens le trekking répond assez largement aux principes du développement durable

“…Mountain agriculture is already under stress as a result of population increase, industrialization and urbanization, competition over resource use, degradation of resources, and insufficient public spending on rural infrastructure and services (Easterling 1996;Darwin 1999). The impact of climate change and tremendous hydrological hazards (drought, river-line floods, flash floods, erosion, rain induced landslides, and so on) is likely to exacerbate these stresses even further (Kostrowicki 1983;Hamilton 1987;Scheling 1988;Tiwari 2000). The outlook for the coming decades is that agricul tural productivity needs to continue to increase and will require more water to meet the demands of grow ing populations (Rosenzweig and Parry 1994;Schlenker, Hanemann, and Fisher 2006).…”

Impacts of climate change and hydrological hazards on monsoon crop patterns in the Lesser Himalaya: A watershed based study

The Lesser Himalaya region is a densely populate d, nonglacial tract of the Himalaya. About 95 percent of the regional population depends on agriculture and forest resources but both have been declining rapidly in recent decades due to climate change and hydrological hazards. The main objective of this study was to assess the integrated impacts of climate change and hydrological hazards on monsoon crop patterns in the Lesser Himalaya through a geographic information system (GIS) database management system (DMS). The DMS comprises four GIS modules: climate informatics, land use informatics, hydro-informatics, and agro-informatics. The Dabka watershed in India's Uttarakhand State is part of the Kosi Basin in the Lesser Himalaya in District Nainital and was chosen as a case study. The climate of the study area, depending on elevation, falls into three climatic zones: subtropical, temperate, and moist temperate, which are favorable for mixed forest, pine forest, and oak forest respectively. The results of the climate-informatics analysis suggest that in recent decades all these climatic zones have shifted towards higher altitudes and the areas of oak and pine forests have decreased. Forest degradation has accelerated hydrological hazards (high runoff, flash floods, river-line floods, soil erosion, and landslides) in monsoon periods, which affected about 22 percent of the cultivated land annually in 2005-2010. Monsoon crop yields decreased by an annual average of 1.40 percent between 1985 and 2010 while the population of the study area increased by an average of 2 percent each year in the same period. The negative correlation between annual crop yields and population growth has led to increased food security risks.
