The Impact

AbstractGlobal climate change has become the most significant challenge of modern times, confronting the lives and security of vulnerable societies around the world. The anticipated impact of climatic variability will be severe on local communities, particularly those residing near high-risk prone zones such as coastal areas and mountain regions. The indigenous knowledge and locally-held beliefs act as a refuge, which also prompt and prohibit the responsiveness towards climatic instabilities. Subsequently, ensuring food and nutritional security is the primary task of strategy makers. Hence, comprehensive knowledge of the indigenous traditional food habits and cultural values, beliefs, and gendered norms need to be explored on a priority basis to address the adverse impact of environmental changes, emphasizing the urgency of the Himalayan societies. Despite that, the integration of indigenous knowledge is not on the priority list of the researcher. Thus, this article reviews the existing literature on customary food habits to analyze the bidirectional association between climate change and the dietary practice of the indigenous communities for adaptation policy. PRISMA Statement technique is used for a systematic review of Scopus and Web of Science databases identified 24 related studies from 14 countries, with a specific focus on the Himalayan region, which resulted into four themes viz. impact of climatic variability of indigenous societies, the impact of climate change on community’s customary food beliefs, the impact of climate change on gender defined norms, climate change adaption strategies. The findings show that the current literature has failed to include the socio-ecological beliefs of traditional communities associated with dietary habits. Thus, the focus should be given to integrate the locally held beliefs of customary societies for the successful adoption of climate change adaptation and food security programs.

The Impact

Indian Western Himalaya has a rich plant diversity/ bio-resources due to the large variations in the altitude (300 to 6000 ms) and climatic conditions from tropical, temperate to alpine. The paper sheds light on the issues and challenges of climate change in the Western Himalaya; its impact on the plant diversity (wild plants, crops, fruits); loss of plant diversity and livelihood of the local communities; impact on the phenology of plant species; possible mitigation strategies to combat the impact of climate change. The Western Himalayan region has a rich diversity of plant diversity or bio resources. These bio resources (wild plants, crops, fruits) have been used by the local communities in the form of traditional medicines and foods from pre-historic periods or since the settlement of human communities in this region. These communities used these bio-resources as a source of income by their cultivation and selling in the markets. They are also involved in the traditional agriculture and horticulture practices and for that dependent on the climatic conditions (rate of precipitation, temperature, humidity) throughout the year. Hence stable environment conditions a pre requisite for better production and productivity. But in the last 100 years an increased in the temperature on earth brought large variation in the climate of Himalayan region too. The extreme climatic conditions will make Himalayan ecosystem more fragile, less productive and more prone towards disasters or natural calamities. Long term planning is required to understand the impact of climate change in the Western Himalaya along with some new strategies to mitigate its impact.

The Impact

<p>Southeast Asia’s electricity supply largely depends on the hydropower resources of the Mekong, Chao Phraya, Irrawaddy, and Salween River Basins. Uncertain precipitation patterns, rising temperature, and other climate-driven changes are exposing these resources to unprecedented risks, prompting decision makers to re-evaluate existing reservoir management strategies through climate change risk assessments. These assessments are important in shaping the operators’ response to hydro-climatic variability and are necessary to ensure energy security in the region. In this study, we developed high-resolution, semi-distributed hydrological models to examine the potential changes of hydropower availability under projected future climate scenarios in the four largest river basins in South East Asia. Specifically, we relied on a novel variant of the Variable Infiltration Capacity (VIC) model that integrates reservoir operations into the routing scheme, warranting a more accurate representation of cascade reservoir systems. Climate change impacts were derived from the outputs of five Global Circulation Models (GCMs) forced by two Shared Socioeconomic Pathways (SSPs 2.6 and 8.5) emission scenarios in the Coupled Model Intercomparison Project Phase 6 (CMIP6). We find that hydropower generation would be altered significantly in all scenarios in terms of temporal variability and magnitude due to the changes in duration and magnitude of the summer monsoon. Our findings further stress the importance of exploring how the impact of climate change on hydropower availability propagates through water-energy systems and call for adaptive reservoir operation strategies.</p>

Abstract We present phenological data for two time periods (1985–1987 and 2014–2016) on major tree species (Shorea robusta, Pinus roxburghii, Myrica esculenta, Quercus leucotrichophora, Rhododendron arboreum, Quercus floribunda, and Machilus duthiei) occurring along an altitudinal gradient of 300–2,200 m asl of Himalayan forests (a data-deficient region identified by the IPCC, 2007), and show that bud break and leafing in trees has advanced at 0.20 days/year, which is associated with a significant (P < 0.001) increase in atmospheric temperature (0.038°C/year) over the years in the study area. Also, the leaf drop period has advanced correspondingly (0.40 days/year); hence, the length of season (LOS) did not increase in these trees. This finding is contrary to the report of increase in LOS due to climatic warming from temperate latitudes of the world and satellite-based studies in Himalayan region. Arguably, phenomena such as bud break and leafing may not be captured by remote sensing, which is critical for determining the impact of climate change on the forest vegetation of the eco-sensitive Himalayan region. We suggest that this phenological earliness may alter forest structure and functioning and associated ecosystem services of these forests in the long run. Study Implications: This study suggests that bud break and leafing in trees has advanced, an advancement that is associated with the significant increase in atmospheric temperature over the years in the study area. However, the leaf drop period has advanced correspondingly; hence, the length of season of trees in the study area did not increase. Nonetheless, the earliness in the leafing and leaf drop have potential implications on forest ecosystem structure and functioning, such as photosynthesis, carbon assimilation, increased asynchrony in plant-pollinators and animal interactions, reproduction success, and herbivory that require further detailed investigation. Warming may also advance seed maturation and desiccation of seeds that may disrupt the synchrony between monsoon and tree seed germination, forest regeneration, and ensuing ecosystem services. Generalizations on a regional scale on the impact of climate change on annual patterns of growth of forests that are based on remote-sensing studies could mask the impact of the premonsoon period, when bud break and leafing take place. These impacts may not be captured by remote sensing; impacts which, in this study, we have found to be critical.

The purpose of this work is to review and analyze the main results of modern research on the impact of climate change on the agro-sphere of Ukraine. Results. Analysis of research has shown that the effects of climate change on the agro-sphere are already being felt today and will continue in the future. The observed climate changes in recent decades have already significantly affected the shift in the northern direction of all agro-climatic zones of Europe, including Ukraine. From the point of view of productivity of the agro-sphere of Ukraine, climate change will have both positive and negative consequences. The positives include: improving the conditions of formation and reducing the harvesting time of crop yields; the possibility of effective introduction of late varieties (hybrids), which require more thermal resources; improving the conditions for overwintering crops; increase the efficiency of fertilizer application. Model estimates of the impact of climate change on wheat yields in Ukraine mainly indicate the positive effects of global warming on yields in the medium term, but with an increase in the average annual temperature by 2 ° C above normal, grain yields are expected to decrease. The negative consequences of the impact of climate change on the agrosphere include: increased drought during the growing season; acceleration of humus decomposition in soils; deterioration of soil moisture in the southern regions; deterioration of grain quality and failure to ensure full vernalization of grain; increase in the number of pests, the spread of pathogens of plants and weeds due to favorable conditions for their overwintering; increase in wind and water erosion of the soil caused by an increase in droughts and extreme rainfall; increasing risks of freezing of winter crops due to lack of stable snow cover. Conclusions. Resource-saving agricultural technologies are of particular importance in the context of climate change. They include technologies such as no-till, strip-till, ridge-till, which make it possible to partially store and accumulate mulch on the soil surface, reduce the speed of the surface layer of air and contribute to better preservation of moisture accumulated during the autumn-winter period. And in determining the most effective ways and mechanisms to reduce weather risks for Ukrainian farmers, it is necessary to take into account the world practice of climate-smart technologies.
