This study applied the Livelihood Vulnerability Index to developing countries' agricultural and natural resourcedependent communities. The index is involved in a comparative analysis of the vulnerability of upstream and downstream communities in Banjar District, which is expected to bear some of the most severe impacts of climate change in South Kalimantan. The major components indices of the Livelihood Vulnerability Index (LVI), such as Socio-demographic profile, Livelihood strategies, Social network, Health, Food, Water, Natural disaster, and climate variability, were calculated based on survey data. The calculated results showed that those farmer households in the downstream areas feel greater exposure (exposure) and sensitivity due to climate variability (floods). Meanwhile, farmer households in the upstream area are more vulnerable in capacity. In addition to identifying susceptible persons and locations, the study gives appropriate knowledge, information, and practical recommendations to support adaptation decisions as predicted by the vulnerability.

“…In the central part of southern Terai, the average annual rainfall decreased at the rate of 10.21 mm/year between 1984 and 2014 (Dhakal et al, 2016). 65% of cultivation is rainfed, hence there are negative impacts on the Rice-Wheat Cropping system due to the spatial and temporal variation in precipitation pattern (Gahatraj et al, 2018). Water stagnated condition in rice prevents aerobic decomposition of soil organic matter (SOM).…”

Rice Wheat Cropping system is a major cropping system in Nepal representing one-fourth of the total cultivated land. 83% of the population are dependent on the system for income and employment. However, there are serious threats to sustainability of the Rice Wheat Cropping system in Nepal. The conventional practices are water, labor, and nutrient intensive. Puddling the soil for rice has degraded soil structure in the field and long turn-around period between rice and wheat has delayed wheat planting. Both have contributed to stagnant yield and therefore to low profitability of the Rice Wheat Cropping system. Various literatures related to conservation agriculture, its practices and its role in maintaining sustainable agriculture were studied and enough information were gathered for argument. Conservation agriculture practice mainly focuses on minimal soil disturbance, crop rotation and mulching. Conservation agriculture includes zero tillage, integrated nutrient management, alternate drying and wetting, bed planting and mulching, and crop rotation to diminish the threats to sustainability of Rice Wheat Cropping system. In Nepal, the extension work has been carried out as Climate Smart Agriculture which comes under Conservation Agriculture. However, less research and hesitation of farmers to adopt the technology have created hurdles in extension of conservation agriculture. Conservation Agriculture has proven itself to be the best cultivation practice to enhance productivity of any land without overexploiting the natural resources. Such technology is important to sustain our agriculture in future. Hence, CA is of utmost importance to sustain the livelihood of Nepalese farmers, which is, Rice-Wheat Cropping system of Nepal.

“…0.52 million ha of the area is affected by drought in Nepal (Tripathi et al, 2019). The spatial and temporal variation in precipitation pattern negatively impacts the rice-wheat cropping since 65% of cultivation is rainfed (Gahatraj et al, 2018). The conventional method of rice cultivation requires about 1500 mm of water after transplanting to complete its life cycle before which seedling raising and puddling requires 50 mm of water (Karkaliya et al, 2018).…”

Rice wheat cropping system has been widely adopted in Nepal since very long, but much less been studied about the sustainability aspects of this practice. South Asian countries-, as well as other rice-growing countries, have already experienced different ecological and environmental impacts of the long-term rice-wheat system. Also,climate change seems to inflict the rice-based farming system to a varied extent depending uponagroecological regions. In the meantime, the growth in yield of rice is plateauing to less than 1.5% although productivity is well below other South Asian countries. With the heightening consumption of agrochemicals and its subsequent impact on air, water and soil have to be taken into consideration. Rice-wheat system being heavy consumer of nutrient and waterraises question about the sustainable consumption of resources. The increasing dominance of hybrid varieties posses' threat of extinction of local landraces of rice. Apart from environmental and agronomic issues it also maybe affected by socio-economic issues of Nepalese farming families. Extensive studies are yet to be done, but practices like conservation agriculture and sustainable intensification practices are found to make system more resilient. The aim of this review is to discuss such issues associated with sustainability and propose some probable sustainability measures.
