Pakistan is an agrarian nation that is among the most vulnerable countries to climatic variations. Around 20% of its GDP is produced by agriculture, and livestock-related production contributes more than half of this value. However, few empirical studies have been conducted to determine the vulnerability and knowledge of livestock herders, and particularly the smaller herders. Comprehending individual perceptions of and vulnerabilities to climate change (CC) will enable effective formulation of CC mitigation strategies. This study intended to explore individual perceptions of and vulnerabilities to CC based on a primary dataset of 405 small livestock herders from three agro-ecological zones of Punjab. The results showed that livestock herders’ perceptions about temperature and rainfall variations/patterns coincide with the meteorological information of the study locations. The vulnerability indicators show that Dera Ghazi Khan district is more vulnerable than the other two zones because of high exposure and sensitivity to CC, and lower adaptive capacity. However, all zones experience regular livelihood risks due to livestock diseases and deaths resulting from extreme climatic conditions, lower economic status, and constrained institutional and human resource capabilities, thus leading to increased vulnerability. The results indicate that low-cost local approaches are needed, such as provision of improved veterinary services, increased availability of basic equipment, small-scale infrastructure projects, and reinforcement of informal social safety nets. These measures would support cost-effective and sustainable decisions to enable subsistence livestock herders to adopt climate smart practices.

Abstract Species inhabiting broad altitudinal gradients are particularly exposed to the effects of global climate change (GCC). Those species reaching mountain tops are the most negatively affected. Here, using ecological niche models we estimated the climate change exposure of endemic amphibians of the most important extra-Andean mountain system of Argentina: the Sierras Pampeanas Centrales. Our results pinpoint that micro-endemic amphibians of this mountain system are heavily exposed to the effects of GCC, with important constraints of suitable climatic conditions for the six analyzed species. Among the most important findings, our models predict a high probability of a total disappearance of suitable climatic conditions for two of the species, currently restricted to mountain tops. This high exposure, in synergy with their very restricted ranges, and other important human induced threats (as fish invasion and emergent diseases), pose a serious threat to these endemic species, which can enter into the “extinction pathway” in a near future if no concrete conservation actions are taken. Our findings provide additional evidence of the great negative impact of GCC in high-altitude centers of endemism.

Climate change and its variability are posing the major challenges influencing the performance of agriculture including annual and perennial horticulture crops. Reduction in production of fruits is likely to be caused by short growing period, which will have negative impact on growth and development particularly due to terminal heat stress and decreased water availability. Hence, crop-based adaptation strategies are needed keeping in view the nature of crop, its sensitivity level and the agro-ecological region. The present investigation was conducted for major sub temperate fruit crops such as apricot, peach and plum in Himachal Pradesh. The investigation was carried out at different altitudinal gradients in fruit growing pockets of Solan district the state. The study was conducted to work out the relationship of weather parameters with phenological stages of major fruit crops and assessment of their vulnerability to climate change under selected altitudinal gradients. The average maximum and minimum temperature showed an increase since last thirty years at all major fruit growing areas, whereas, annual rainfall revealed an erratic trend. The fruit growing areas at 1000-1200 m amsl of Solan district obtained highest score (0.56) and were most vulnerable for stone fruit crops production while those at 1400-1600 m above mean sea level (amsl) were least vulnerable amongst the selected altitudes. To cope with climatic changes farmers have adopted various adaptation and mitigation strategies such as improved water conservation techniques, varietal shifts and crop diversification with other fruits like kiwi, pomegranate and vegetables in the region.

Impacts Of Climate Change

Confidence in the projected impacts of climate change on agricultural systems has increased substantially since the first Intergovernmental Panel on Climate Change (IPCC) reports. In Africa, much work has gone into downscaling global climate models to understand regional impacts, but there remains a dearth of local level understanding of impacts and communities’ capacity to adapt. It is well understood that Africa is vulnerable to climate change, not only because of its high exposure to climate change, but also because many African communities lack the capacity to respond or adapt to the impacts of climate change. Warming trends have already become evident across the continent, and it is likely that the continent’s 2000 mean annual temperature change will exceed +2°C by 2100. Added to this warming trend, changes in precipitation patterns are also of concern: Even if rainfall remains constant, due to increasing temperatures, existing water stress will be amplified, putting even more pressure on agricultural systems, especially in semiarid areas. In general, high temperatures and changes in rainfall patterns are likely to reduce cereal crop productivity, and new evidence is emerging that high-value perennial crops will also be negatively impacted by rising temperatures. Pressures from pests, weeds, and diseases are also expected to increase, with detrimental effects on crops and livestock. Much of African agriculture’s vulnerability to climate change lies in the fact that its agricultural systems remain largely rain-fed and underdeveloped, as the majority of Africa’s farmers are small-scale farmers with few financial resources, limited access to infrastructure, and disparate access to information. At the same time, as these systems are highly reliant on their environment, and farmers are dependent on farming for their livelihoods, their diversity, context specificity, and the existence of generations of traditional knowledge offer elements of resilience in the face of climate change. Overall, however, the combination of climatic and nonclimatic drivers and stressors will exacerbate the vulnerability of Africa’s agricultural systems to climate change, but the impacts will not be universally felt. Climate change will impact farmers and their agricultural systems in different ways, and adapting to these impacts will need to be context-specific. Current adaptation efforts on the continent are increasing across the continent, but it is expected that in the long term these will be insufficient in enabling communities to cope with the changes due to longer-term climate change. African famers are increasingly adopting a variety of conservation and agroecological practices such as agroforestry, contouring, terracing, mulching, and no-till. These practices have the twin benefits of lowering carbon emissions while adapting to climate change as well as broadening the sources of livelihoods for poor farmers, but there are constraints to their widespread adoption. These challenges vary from insecure land tenure to difficulties with knowledge-sharing. While African agriculture faces exposure to climate change as well as broader socioeconomic and political challenges, many of its diverse agricultural systems remain resilient. As the continent with the highest population growth rate, rapid urbanization trends, and rising GDP in many countries, Africa’s agricultural systems will need to become adaptive to more than just climate change as the uncertainties of the 21st century unfold.

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.

AbstractClimate change impacts on agriculture have been intensifying in the Northeastern United States. In order to encourage the adoption of climate change adaptation and mitigation practices by farmers, it is critical to understand their perspectives on the risks they face and actions they are taking. However, very few empirical studies have considered how farmers are interpreting and responding to climate impacts, risks and opportunities in the Northeast. This study investigates farmer views and decisions related to climate change using data from six farmer focus groups conducted across New York and Pennsylvania. The study examined how farmers perceived climate impacts on their farms, the practices they are willing to adopt, and how perceived risks and vulnerability affect farmers’ decision-making related to adaptation and mitigation strategies. Although farmers articulated concern regarding climate impacts, they also made clear that other business pressures, such as profitability, market conditions, labor availability or government regulations were often more critical issues that affected their decision-making. Decisions about adopting climate change adaptation and mitigation practices vary widely, and personal experience with extreme weather and changing seasons affected decision-making. The findings from this study provide improved understanding of farmers’ needs and priorities, which can help guide land-grant researchers, extension and policymakers in their efforts to develop and coordinate a comprehensive strategy to address climate change impacts on agriculture in the Northeast.

Drought risk analysis can help improve disaster management techniques, thereby reducing potential drought risk under the impacts of climate change. This study analyses observed and model-simulated spatial patterns of changes in drought risk in vulnerable eco-regions in China during 1988–2017 and 2020–2050 using an analytic hierarchy process (AHP) method. To perform a risk assessment and estimation of a drought disaster, three subsystems—namely hazard, vulnerability and exposure—are assessed in terms of the effects of climate change since the middle of the 21st century: (i) Hazards, represented by climate anomalies related to the drought process, such as changes in rainfall averages, temperature averages and evaporation averages; (ii) vulnerability, encompassing land use and mutual transposition between them; (iii) exposure, consisting of socioeconomic, demographic, and farming. The results demonstrated that high hazards continue to be located in the arid zone, high vulnerability levels occur in the Junggar Basin and Inner Mongolia Plateau, and high exposure levels occur Loess Plateau and southern coastal area. In this way, the results provide exhaustive measures for proactive drought risk management and mitigation strategies.

Abstract. Climate change is a global environmental threat to all economic sectors, particularly the agricultural sector. Pakistan is one of the negatively affected countries from climate change due to its high exposure to extreme events and low adaptive capacity. In Pakistan, farmers are the primary stakeholders in agriculture and are more at risk due to climate vulnerability. Based on farm household data of 450 households collected from three districts in three agro-ecological zones in Punjab province of Pakistan, this study examined how farmers perceive climate change and how they adapt their farming in response to perceived changes in climate. The results demonstrate that awareness to climate change persists in the area, and farm households make adjustments to adapt their agriculture in response to climatic change. Overall 58% of the farm households adapted their farming to climate change. Changing crop varieties, changing planting dates, plantation of trees and changing fertilizer were the main adaptation methods implemented by farm households in the study area. Results from the binary logistic model revealed that education, farm experience, household size, land area, tenancy status, ownership of tube-well, access to market information, information on weather forecasting and extension all influence the farmers' choice of adaptation measures. Results also indicate that adaptation to climate change is constrained by several factors such as lack of information; lack of money; resource constraint and shortage of irrigation water in the study area. Findings of the study suggest the need of greater investment in farmer education and improved institutional setup for climate change adaptation to improve farmers' wellbeing.

Several climate change related factors including temperature increases, changes in rainfall patterns and outbreak of pests and diseases negatively affect agricultural productivity and food security . Climate change effects significantly in crease production risk and rural vulnerability, particularly in regions that already suffer from chronic soil and water resource scarcity or high exposure to climatic extremes, such as droughts and flooding. The effects of climate change on agriculture may depend not only on changing climate conditions, but also on the agricultural sector’s ability to adapt through changes in technology and demand for food. Significant proportions of the growing populations in developing countries derive their livelihoods f rom agriculture and are, therefore, vulnerable to climate change effects . The task of eradicating extreme poverty and hunger by 2015, as per Millennium Development Goals , will require both regional and global research efforts and concrete actions among which biotechnology adoption plays a key role. Advances in biotechnology can lead to cutting -edge technologies in agriculture. However, sub -Saharan Africa faces an uphill task with regard to the adoption and use of agricultural biotechnology. The potential to improve the livelihoods of resource -poor farmers is a strong incentive to meet the challenge. This paper reviews research work on climate change in relation to increasing food insecurity situation in sub -Saharan Africa (SSA) , and the significance of plant biotechnology in reversing the disturbing food insecurity trends on the continent . To move plant biotechnology forward, the paper recommends that African countries institutionalize effective bio -safety regulatory frameworks, and commit resources to capacity building and provision of infrastructure for biotechnology development . Funding of Genetically Modified Organism ( GM O) related research into tropical and sub- tropical staple foods , suitable for the needs of small- scale farmers in SSA countries , is strongly recommended. There is also the need for researchers to engage in effective education and communication with the general public so as to enhance adoption of biotechnological products in Africa .
