Abstract and Figures

Under global warming and climate change (CC), the vulnerable piece of land is India’s Eastern-Himalayan-Region (EHR), where millions’ livelihood activities are at risk. Quantifying the degree of CC-induced vulnerability over the highly climate-sensitive mountain zone is challenging due to data inadequacy. This paper attempted to assess the CC perception of kiwifruit growers under EHR and the impact of CC on its cultivation. Perceived and scientific data were used for accurate decision-support information. The climatic variables of two locations were analyzed for trend using Mann–Kendall’s test. Results suggested that the rainfall trend was found non-significant for both locations, but there was a negative trend during winter for Pasighat and during all seasons for Itanagar. Maximum temperature exhibited an increasing trend for annual, and minimum temperature showed an increasing trend across seasons for the Pasighat region. For the Itanagar region, the maximum temperature was found to have a significantly increasing trend in all seasons, while the minimum temperature showed an increasing trend during winter and annual seasons. Morning relative humidity showed an increasing trend for annual data for Pasighat, while annual evening relative humidity was significantly increased for Itanagar. The study shows that the indigenous farming communities were following shifting cultivation and diversifying their traditional agriculture to kiwifruit cultivation as an adaptation strategy. The community had a clear perception of CC trends and an inadequate perception of the impact on agriculture, therefore, engaging indigenous communities and other stakeholders to postulate a comprehensive adaptation and mitigation strategy for CC.

Abstract
Under global warming and climate change (CC), the vulnerable piece of land is India’s Eastern-Himalayan-Region (EHR),
where millions’ livelihood activities are at risk. Quantifying the degree of CC-induced vulnerability over the highly cli-
mate-sensitive mountain zone is challenging due to data inadequacy. This paper attempted to assess the CC perception of
kiwifruit growers under EHR and the impact of CC on its cultivation. Perceived and scientific data were used for accurate
decision-support information. The climatic variables of two locations were analyzed for trend using Mann–Kendall’s test.
Results suggested that the rainfall trend was found non-significant for both locations, but there was a negative trend during
winter for Pasighat and during all seasons for Itanagar. Maximum temperature exhibited an increasing trend for annual,
and minimum temperature showed an increasing trend across seasons for the Pasighat region. For the Itanagar region, the
maximum temperature was found to have a significantly increasing trend in all seasons, while the minimum temperature
showed an increasing trend during winter and annual seasons. Morning relative humidity showed an increasing trend for
annual data for Pasighat, while annual evening relative humidity was significantly increased for Itanagar. The study shows
that the indigenous farming communities were following shifting cultivation and diversifying their traditional agriculture
to kiwifruit cultivation as an adaptation strategy. The community had a clear perception of CC trends and an inadequate
perception of the impact on agriculture, therefore, engaging indigenous communities and other stakeholders to postulate a
comprehensive adaptation and mitigation strategy for CC.
1 Introduction
The great Himalayan Mountain protects the entire northern
and northeastern part of India. The Himalayan Mountain
regulates the climatic condition, agro-ecological situa-
tion, culture and livelihood of India and other countries.
It is extended to about 595,000 km2 from Afghanistan to
Myanmar (Anonymous 2023a, b and NitiAayog 2018).The
Himalayan region is divided into the Western, Central, and
Eastern Himalayan regions (EHR). The EHR is a meeting
point of five countries: India, Nepal, Bhutan, China, and
Myanmar. It is extended from eastern Nepal, the Darjeeling
district of West Bengal, the entire North-eastern Region
of India, and Bhutan, Tibet Autonomous region to Yun-
nan in China and Northern Myanmar (NitiAayog. 2018).
Excluding the Polar Regions, the Himalayas have the larg-
est glacier cover and are termed the third pole (Vohra 1996;
Dyurgerov 2001; Qiu 2008; Scheel etal. 2011). About 17%
of the greater Himalayas are encapsulated by glaciers,
ice, and snow (Dyurgerov and Meier 2005; IPCC 2007).
The ten largest rivers in Asia originated from Himalayan
glaciers. The Indian Himalayan Region (IHR) is home to
nearly 50 million Indians. IHR is characterized by diverse
environmental, socio-economical, cultural, and political
systems (NitiAayog 2022). However, the environmental

Climate change, a pressing global concern, poses significant challenges to agricultural systems worldwide. Among the myriad impacts of climate change, the cultivation of kiwifruit trees (Actinidia spp.) faces multifaceted challenges. In this review, we delve into the intricate effects of climate change on kiwifruit production, which span phenological shifts, distributional changes, physiological responses, and ecological interactions. Understanding these complexities is crucial for devising effective adaptation and mitigation strategies to safeguard kiwifruit production amidst climate variability. This review scrutinizes the influence of rising global temperatures, altered precipitation patterns, and a heightened frequency of extreme weather events on the regions where kiwifruits are cultivated. Additionally, it delves into the ramifications of changing climatic conditions on kiwifruit tree physiology, phenology, and susceptibility to pests and diseases. The economic and social repercussions of climate change on kiwifruit production, including yield losses, livelihood impacts, and market dynamics, are thoroughly examined. In response to these challenges, this review proposes tailored adaptation and mitigation strategies for kiwifruit cultivation. This includes breeding climate-resilient kiwifruit cultivars of the Actinidia species that could withstand drought and high temperatures. Additional measures would involve implementing sustainable farming practices like irrigation, mulching, rain shelters, and shade management, as well as conserving soil and water resources. Through an examination of the literature, this review showcases the existing innovative approaches for climate change adaptation in kiwifruit farming. It concludes with recommendations for future research directions aimed at promoting the sustainability and resilience of fruit production, particularly in the context of kiwifruit cultivation, amid a changing climate.

Kiwifruit is a perennial vine originating from China where it has been grown for centuries. In the United States, green kiwifruit (Actinidia deliciosa) is primarily produced commercially in California. They are fuzzy, green fleshed and well known in the marketplace. Kiwifruit plants require low to moderate soil pH, adequate winter chilling and adequate precipitation to guarantee plant development and good fructification. Actinidia chinesis or golden kiwifruit are smooth skinned, feature golden flesh and are a more recent introduction into the global market. Kiwifruit crops have attributes that favor production in east Texas, including low pest problems, current long market window for the fruit, strong consumer acceptance and a growing marketplace. There are few kiwifruit study plots in Texas that will determine its adaptation in the region for commercial potential. In February 2021, Texas experienced a historic freezing event. Vines at evaluation plots were exposed to very low freezing temperatures, which could permanently damage the plants. This study covered the assessment of kiwifruit at five locations after freeze events from November 2020 to March 2021. The study indicated that the kiwifruit varieties experienced different responses to the freeze effect on plants. Green kiwifruit cultivars were more susceptible to the February freeze, thereby presenting more damage on plants than gold cultivars. Also, the use of trunk protection in Hayward cultivar did not reduce/prevent plant damage. Another study, ‘Bruno’ rootstock had a different proportion of plant injury among study sites: Crockett, Nacogdoches, and Simonton (TX). A chilling hours map for east Texas counties was created using weather data from the past ten years. The map can be used as an auxiliary tool when deciding on cultivars according to their chill hour requirements. The suitability map to grow kiwifruit in the east exhibited a great portion of eastern Texas being optimal areas to grow kiwifruit. The suitability map is an additional resource to use in decision-making to grow the crop when in conjunction with other agricultural management.

CONTEXT: Global and national agricultural development policies normally tend to focus more on enhancing farm productivity through technological changes than on better use of existing technologies. The role of improving technical efficiency in greenhouse gas (GHG) emissions reduction from crop production is the least explored area in the agricultural sector. But improving technical efficiency is necessary in the context of the limited availability of existing natural resources (particularly land and water) and the need for GHG emission reduction from the agriculture sector. Technical efficiency gains in the production process are linked with the amount of input used nd the cost of production that determines both economic and environmental gains from the better use of existing technologies. OBJECTIVE: To assess a relationship between technical efficiency and GHG emissions and test the hypothesis that improving technical efficiency reduces GHG emissions from crop production. METHODS: This study used input-output data collected from 10,689 rice farms and 5220 wheat farms across India to estimate technical efficiency, global warming potential, and emission intensity (GHG emissions per unit of crop production) under the existing crop production practices. The GHG emissions from rice and wheat production were estimated using the CCAFS Mitigation Options Tool (CCAFS-MOT) and the technical efficiency of production was estimated through a stochastic production frontier analysis. RESULTS AND CONCLUSIONS: Results suggest that improving technical efficiency in crop production can reduce emission intensity but not necessarily total emissions. Moreover, our analysis does not support smallholders tend to be technically less efficient and the emissions per unit of food produced by smallholders can be relatively high. A large proportion of smallholders have high technical efficiency, less total GHG emissions, and low emissions intensity. This study indicates the levels of technical efficiency and GHG emission are largely influenced by farming typology, i.e. choice and use of existing technologies and management practices in crop cultivation. SIGNIFICANCE: This study will help to promote existing improved technologies targeting GHG emissions reduction from the agriculture production systems.

Climate change anxiety is becoming recognized as a way in which climate change affects mental health. It is not only observed in populations that suffer the most from the direct impacts of climate change but also can be trigged by the mere thought and perception about such impacts. Although climate change is a global problem that is a cause for concern around the world, research on climate anxiety has only recently utilized validated measures, and it has mostly been conducted in Western and developed societies. In response to this research gap, we conducted a cross-national study of climate change anxiety using the Climate Change Anxiety Scale, with participants (N = 4000) from four of the top emitters in the world (China, India, Japan, and the U.S.) which vary in their climate change vulnerabilities and resilience. We demonstrated that the widely adopted measure of climate change anxiety exhibited configural and metric invariance in the four countries. Climate change anxiety was apparently higher in the Chinese and Indian populations than in the Japanese and American populations. There were some demographic correlates of climate change anxiety, but the pattern was not always consistent across the countries. Climate change anxiety was positively associated with engagement in climate action in all four countries, but apparently more so for sustainable diet and climate activism than resource conservation and support for climate policy. The effect was driven more robustly by the cognitive-emotional impairment dimension than the functional impairment dimension of climate change anxiety. Taken together, these observations suggest that the Climate Change Anxiety Scale can be used to assess climate change anxiety across countries, and that there are both similarities and variations across different societal contexts with respect to the experience of climate change anxiety. Future research must take these complexities into consideration.

Context: Millions of people living in the Eastern Gangetic Plains (EGP) of India engage in agriculture to support their livelihoods yet are income poor, and food and climate insecure. To address these challenges, policymakers and development programs invest in irrigation-led agricultural intensification. However, the evidence for agricultural intensification to lift farmers' incomes above the poverty line remains largely anecdotal. Objective: The main objective of this study is to use a large household survey (n = 15,572; rice: 8244, wheat: 7328; 2017/18) to assess the link between agricultural intensification and personal daily incomes from farming (FPDI) in the rice-wheat systems of the EGP - the dominant cropping system of the region. Methods: We use the Intensification Benefit Index (IBI), a measure that relates farm size and household size to FPDI, to assess how daily incomes from rice-wheat production change with irrigation-led intensification across the EGP. Results and conclusions: Relative to the international poverty line of 1.90 Purchasing Power Parity (PPP)day1andaccountingforvariationsinHHsizeintheanalysis,wefoundthatsmallfarmsizeslimitthepotentialforagriculturalintensificationfromirrigationtotransformthepovertystatusofhouseholdsinthebottomthreequartilesoftheIBI.TheestimatedmedianFPDIofhouseholdswithintensifiedsystemsinthebottomthreequartilesisonly0.51PPP day-1 and accounting for variations in HH size in the analysis, we found that small farm sizes limit the potential for agricultural intensification from irrigation to transform the poverty status of households in the bottom three quartiles of the IBI. The estimated median FPDI of households with intensified systems in the bottom three quartiles is only 0.51 PPP day-1 (a 0.15 PPPgain).ThemedianFPDIincreasesto2.10PPP gain). The median FPDI increases to 2.10 PPP day-1 for households in the upper quartile of the IBI distribution (a 0.30 PPP$ gain). Irrigation-led agricultural intensification of rice-wheat systems in the EGP may provide substantial benefits for resilience to climatic change and food security but achieving meaningful poverty reduction will require complementary investments. Significance: Transforming the poverty status of most smallholder farmers in the EGP requires diversified portfolios of rural on- and off-farm income-generating opportunities. While bolstering food- and climate security, agronomic intervention programs should consider smallholders' limited monetary incentives to invest in intensification. Irrigation-led agricultural intensification programs and policies should explicitly account for the heterogeneity in household resources, irrigation levels, and degree of dependence on agricultural income.

A critical global policy question is how the environmental management interventions could be repurposed to meet the sustainable development goals and their target for food security, climate protection, and environmental sustainability. A common challenge facing food systems in developing countries is to improve agricultural productivity to ensure food security for all without increasing the emission of greenhouse gases (GHGs) from agriculture. Climate-smart agriculture (CSA) approaches help to reduce GHG emissions from agriculture and address the challenges of climate change (CC) and food insecurity. Yet, CSA lack understanding of the institutional arrangements and policy processes. This paper examines 38 aspects to assess the institutional and policy status for CC mitigation and adaptation and CSA in Nagaland, India. Furthermore, we use these aspects to develop a scale to measure the policy and institutional environment for mitigation and adaptation of CC and implementation of CSA. Nagaland is relatively in a better position in nine aspects, although it can improve. Methodologically, the scale developed in this paper and the identified factors can help study the institutional and policy status of a country, state, or region. We identify several implications for understanding CC and CSA institutions and policies for informing policy research and practice. HIGHLIGHTS This paper examines 38 different institutional and policy variables affecting the mitigation and adaptation of climate change (CC) strategies supporting the implementation of climate-smart agriculture (CSA).; Evidence-based strategies are identified for scaling up the CSA interventions in the Indian context.; The proposed scale is consistent to measure the institutional and policy status concerning CC mitigation and adaptation and implementation of CSA.;

CONTEXT Long-Term Field Experiments (LTEs) were implemented to study the long-term effects of different management practices, including tillage, fertilization and crop rotation under otherwise constant conditions. Climate change is expected to change these conditions, challenging interpretation of LTE data with regard to the distinction between climate change and management effects. OBJECTIVE The objective of the study was to quantify the expected, spatially differentiated changes of agroclimatic conditions for the German LTE sites as a precondition for modelling and LTE data interpretation. METHODS We developed a framework combining spatially distributed climate data and LTE metadata to identify the possible climatic changes at 247 LTE sites with experiments running for 20 years or more. The LTEs were classified using the following categories: fertilization, tillage, crop rotation, field crops or grassland, conventional or organic. We utilized climate variables (temperature, precipitation) and agroclimatic indicators (aridity, growing degree days, etc.) to compare a baseline (1971–2000) with future periods (2021−2100) under the IPCC's Shared Socio-economic Pathways (SSP). A comprehensive LTE risk assessment was conducted, based on changes in climate variables and agroclimatic indicators between baseline and future scenarios. RESULTS AND CONCLUSIONS Under the most extreme scenario (SSP585), 150 LTEs are expected to shift from humid and dry sub-humid to semi-arid conditions. Frost days in LTE areas are expected to decline by 81%, and the growing season to lengthen by up to 92%. The spatial differentiation of expected climate change also facilitates the identification of suitable sites for future agricultural practices and may inform the design of new LTEs. SIGNIFICANCE Our results may guide the interpretation of LTE data regarding the effect of climate change, facilitating future soil crop modelling studies with LTE data and providing information for planning new LTE sites to support future agricultural research and/or adapting management on existing LTE sites. The framework we developed can easily be transferred to LTE sites in agricultural regions worldwide to support LTE research on climate change impacts and adaptation.

The evidence linking nature and human wellbeing is compelling. Yet, there is a lack of understanding regarding which aspects of nature contribute to wellbeing and the role biodiversity plays specifically. This knowledge gap hampers our ability to understand and manage natural environments from an ecological perspective to improve human wellbeing. To investigate the impact of biodiversity on wellbeing in a range of contexts, there is a need for a psychometric scale. Here, we present BIO-WELL, a novel, reliable and validated self-reported wellbeing scale designed to investigate the biodiversity-health/wellbeing relationship. We describe the conceptual foundation, empirical development and psychometric evaluation of BIO-WELL. We detail five studies, involving 2962 participants, describing the steps taken in the scale's development: (1) a series of deliberative workshops to identify how people conceptualise biodiversity metrics and attributes, and the impact these have on wellbeing; (2) an in-depth qualitative analysis of biodiversity-focused stem questions and wellbeing response items, assessed through an expert panel, focus groups and cognitive interviewing techniques; (3) combined methods associated with classical test theory (e.g. factor analysis) and more modern measurement approaches drawn from item response theory to develop the scale; (4) a confirmatory factor analysis alongside classical test and item response theories to evaluate the scale; and (5) scale validation including discriminant/convergent, concurrent and predictive. The studies demonstrate that BIO-WELL is a valid and reliable scale with strong psychometric properties. We discuss ways it could be applied in research, policy and practice to further develop our conceptual and empirical understanding of the biodiversity-health relationship and assess the effectiveness of related interventions.

This study seeks to identify the change points, tendencies, and trends in climatic parameters and to investigate their relationship with forest cover loss and carbon dioxide (CO2) emission in the Garo Hills region of Northeast India.This study is based on secondary data on Precipitation, Maximum Temperature, Minimum Temperature, Relative Humidity, Tree cover loss, and CO2 emission in Garo Hills from 1984 to 2019. Mann-Kendall's and Sen's slopes were employed to calculate the trend of monthly and seasonal climatic parameters, and Pettitt's test was used to estimate the breakpoints.We further attempted to identify the relationship between the variables under consideration using Pearson's correlation and regression analysis. The results indicate that precipitation levels were generally decreasing over the majority of months and seasons.The maximum temperature showed a marked increase, while the minimum temperature experienced a decrease in all seasons after 2008. From 1999 onwards, the relative humidity has been on the rise in all seasons except monsoon. Regression analysis reveals that the relative humidity and maximum temperature contributed negatively to precipitation. The maximum temperature was positively correlated with both forest cover loss (r = +0.58) and CO2 emission (r = +0.59), while the minimum temperature was negatively correlated with both (r = −0.59 and r = −0.59). This study will provide stakeholders with an understanding of how weather factors vary over time, how forest cover loss and CO2 emissions affect weather patterns in the region, and how to develop climate mitigation strategies.

CONTEXT Both long-term climate trend and interannual climate variability are projected to affect agricultural activities. Actually, major changes in climate patterns have already occurred, affecting crop yields and livestock productivity. OBJECTIVE This study aims to assess the effects of both interannual temperature and precipitation variability and long-term climate trend on the land productivity of Italian farms. Italy represents an interesting example, as the country is largely affected by the effects of climate change and climate variability, and its agricultural sector shows heterogeneous conditions, including climatic, topographical and socio-economic features. METHODS The methodological approach considers the effects on land productivity of a set of farm structural and economic characteristics and climate-related variables, by considering farm-level data. A dynamic panel model is estimated via System Generalized Method-of-Moments using a constant panel of 2051 farms observed over the period from 2008 to 2017. Data are extracted from the Italian Farm Accountancy Data Network. RESULTS AND CONCLUSIONS Results suggest that when coming to farm-level data and addressing the changes in the climate in both the long and the medium term, a negative impact is found on LP because of higher temperatures in the colder seasons and in spring, and because of larger spring cumulative rainfall. On the opposite, wetter summers seem to positively impact LP. As regards Mediterranean regions only a positive impact of larger spring cumulative rainfall is found. Besides, managerial and structural farms' characteristics seem to play a major role in influencing farm performance. SIGNIFICANCE This study represents a first attempt in the direction of estimating the impact of climate change on farms' land productivity, by using micro-data to prevent aggregation biases and controlling for both managerial and structural farms' characteristics.

Climate change significantly impacts agriculture. Building an informed and collaborative process among stakeholders remains vital in minimizing climate risks and building climate-adaptive and resilient agricultural systems in sub-Saharan Africa (SSA). However, stakeholders’ involvement and collaboration in agriculture decision-making are framed by institutional, power, and resource dynamics, often ignoring vulnerable stakeholders most susceptible to climate shocks. These collaborative dynamics are less studied in the climate adaptation literature, especially in the context of Ghana and SSA. This study promotes stakeholder engagement and collaboration in climate-adaptive and conservation agriculture (CA) by examining the influence of and relationship dynamics among key stakeholders in the northern region of Ghana (NRG). Drawing from the normative stakeholder theory and literature on climate adaptation intervention, we use multiple qualitative research methods (e.g. brainstorming, semi-structured interviews, and focus group sessions) to profile and explore stakeholders’ roles, interests, and collaboration in CA and adaptation interventions. Our findings suggest that collaborations in CA in these smallholder farming communities are often fragmented, providing few collaboration advantages to smallholder farmers. Where collaboration occurs, it is often characterized by redundancy or duplication of roles and functions performed by stakeholders, poor coordination among key government actors, or by conflictual relationships among non-governmental organizations (NGOs); relationships amongst stakeholders are often driven by conflicting interests and asymmetric power differentials. These findings suggest that measures to engage stakeholders must carefully consider aligning stakeholders’ interests and addressing power differentials, which are necessary to minimize conflicts in collaborative governance arrangements for adaptation and CA.
