Abstract
The concept of adaptive capacity has received significant attention within social-ecological and environmental change research. Within both the resilience and vulnerability literatures specifically, adaptive capacity has emerged as a fundamental concept for assessing the ability of social-ecological systems to adapt to environmental change. Although methods and indicators used to evaluate adaptive capacity are broad, the focus of existing scholarship has predominately been at the individual- and household- levels. However, the capacities necessary for humans to adapt to global environmental change are often a function of individual and societal characteristics, as well as cumulative and emergent capacities across communities and jurisdictions. In this paper, we apply a systematic literature review and co-citation analysis to investigate empirical research on adaptive capacity that focus on societal levels beyond the household. Our review demonstrates that assessments of adaptive capacity at higher societal levels are increasing in frequency, yet vary widely in approach, framing, and results; analyses focus on adaptive capacity at many different levels (e.g. community, municipality, global region), geographic locations, and cover multiple types of disturbances and their impacts across sectors. We also found that there are considerable challenges with regard to the ‘fit’ between data collected and analytical methods used in adequately capturing the cross-scale and cross-level determinants of adaptive capacity. Current approaches to assessing adaptive capacity at societal levels beyond the household tend to simply aggregate individual- or household-level data, which we argue oversimplifies and ignores the inherent interactions within and across societal levels of decision-making that shape the capacity of humans to adapt to environmental change across multiple scales. In order for future adaptive capacity research to be more practice-oriented and effectively guide policy, there is a need to develop indicators and assessments that are matched with the levels of potential policy applications.
Climate variability and the responses of crop yields to agricultural drought in the East Wollega Zone, Oromia National Regional State, Ethiopia
Authors: Fayera Tasfaye 
Published: April 2022

AbstractSmallholder farmers in Ethiopia have been facing severe climate related hazards; droughts and floods that negatively affect their livelihoods. This study was aimed to assess climate variability and the responses of crop yields to climate induced agricultural drought. Time-series crop yields (1993-2018) and climate data (1989 to 2019) was obtained from Central Statistical Agency and NASA’s portal respectively. The changes in temperature and precipitation were analyzed using Mann Kendall trend test. The agricultural drought index was analyzed using R-software. The correlation between the selected yield crops and drought indices were evaluated using Pearson correlation coefficient. Determinants on climate change adaptation strategies were assessed using a multinomial logit model. The trends of seasonal and annual minimum temperatures and spring maximum temperature results were significantly warmed up (P <0.05).However, both seasonal and annual rainfall was slightly decreased. Moderate to severe agricultural drought intensities happened 7 times and one very wet year occurred during three decades. As the result, about 0.70% of the total land area was affected by moderate drought while about 30.73% of the land area was affected by moderate wet soil moisture and 68.57% of the rest others were observed as harmless land areas. The Person’s correlation coefficients showed that crop yields due to the drought interruption were 93.9, 92.4, and 92.5% for maize, wheat, and finger millet, respectively. Determinants depicted that sex, family size, extension, and education were significantly affected soil and water conservation practice and tree planting at (P <0.05). Therefore, the efforts of local government and stakeholders should be superior to build the capacity of farmers to use appropriate agricultural technologies and supply drought & wet tolerant crop varieties; improve research and development programs.

Abstract
Climate change is indicated to result in drought on agricultural land. In addition, increasing dryness can also cause changes in soil acidity, and these conditions can affect the growth and content of secondary metabolites of plants. Parijoto (Medinilla veruccosa) has health benefits, including lowering blood glucose levels, inhibiting the growth of cancer cells, and is traditionally believed to increase fertility during pregnancy. GA3 and PGPRs (Plant Growth Promoting Rhizobacteria) as elicitors are expected to induce and increase the production of phytoalexins and secondary metabolites. This study aimed to obtain the interaction between GA3 and PGPRs to increase the growth and antioxidant content of parijoto in acid soil. The study used a completely randomized design with two factors (GA3 25 ppm; 50 ppm; 75 ppm/plant and PGPR 2.5 g; 5.0 g; 7.5 g/l). In this study, Rowo Pening peat soil media after being given dolomite increased its pH with very high CEC, high Nitrogen, low P, and K. The results showed that the GA3 and PGPRs had no significant effect on growth. There was a positive correlation between plant height, number of leaves, and root volume. The concentration of GA3 75 ppm and PGPRs 2.5 g/l gave higher antioxidant content than other treatments.

Abstract
Climate change requires the agricultural sector to be more precise in water management. Rainfed lands and irrigated lands with no year-round water supply require an efficient way of using water in the dry season. One of the efforts to utilize irrigation efficiently is to develop subsurface seepage irrigation techniques using pottery. This study aims to determine the composition of the pottery material, the ratio of sand, silt and clay which is optimal for the growth of chilli plants. The experiment was carried out with plots arranged in a nested design with a treatment of five pottery materials with different compositions of clay, soil and sand, and tested on entisol and alfisol soils. The results showed that the pottery irrigation with a combination of pottery material composition on two types of soil affected the weight of chilli fruit. Pottery with a composition of 70% clay and 30% sand is the most effective pottery for chilli and yields on surface growth irrigation.

Abstract
Purple Cone Flower (Echinacea purpurea) is one of the introduced medicinal plants originating from America which has its native habitat growing in subtropical countries with optimal growth conditions of low temperature and full sun exposure. Problems that occur in climate change between subtropics and tropics, especially in Indonesia will have an impact on the less than optimal growth and development of plants so that it will reduce the production and quality of ekinase yields. One way to improve ekinase can suitable in Indonesia (especially in the lowlands) is by adding biochar as a soil enhancer and hormones. The aims to study the interaction between the addition of biochar and the level of hormone dose on the growth rate of ekinase. The research method used a Split-Plot Completely Randomized Block Design. The results show the interaction between the type of biochar and hormone dose. The best results were shown in the treatment of giving husk charcoal and 6 ml/L hormones of 27.67 cm for plant height and 89.67 cm2 for leaf area. The formation of the highest number of leaves was 26 in the treatment of husk charcoal and hormone 2 ml/L. The best results were wood charcoal and hormone treatment 6 ml/L of 0.1467 for the rate of photosynthesis and 0.02937 for the rate of transpiration. Treatment with a dose of 6 ml/L hormone can optimize the growth rate of ekinase.

Published: April 2022

Abstract
Farmers are synonymous with poverty because of the great uncertainty about the impact and magnitude of climate variability. Adaptation efforts, in principle, minimize vulnerability to impacts caused by climate variability. This study aims to see the level of adaptation of farmers and the factors that influence it. A randomly selected 100 rainfed farmers survey was conducted in Seluma Regency, Bengkulu, from June to September 2020. The analysis used to measure the level of adaptation was to compare the number of adaptations adopted by farmers with the total adaptation used in this study and to analyze the factors that affect the level of adaptation using multiple regression models. The results showed that rainfed farmers have a low of adaptation to climate variability. Most farmers make adjustments to planting time, replace climate-resistant varieties, and take advantage of government assistance as a form of adaptation to climate variability. The level of adaptation of rainfed farmers to climate variability is influenced by experience, income, and farmer group membership.

Published: April 2022

Abstract
Drought occurs almost every dry season in Grobogan District, Central Java. Climate change has resulted in an atypical monthly rainfall distribution, which, along with limestone geology, has made water scarce in some months. One of the efforts to mitigate drought disasters is to revitalize water resources from existing springs. The research aims to develop a spring protection plan through a geological-spatial and participatory approach. The research location is in Kradenan Sub-District, Grogoban District, Central Java Province. The research method starts with identifying springs, delineation of springshed area, formulation of spring and springshed management, and discussion and socialization with stakeholders. The identification results show that the springs are classified as “umbul wadon” type with water discharge ranging from 0.9 to 4.8 l/minute, forming a radial pattern. The area of the springshed is 3,347.7 ha, with more than 70% of the land covered by teak forest plantations. The recommendations for spring conservation activities are organized into three zones: Zones I, II, and III, which differ in range radius, function, and proposed management. In each zone and type of land uses, the potential risk of pollution, prohibited activities, protection strategies and programs, and interested parties as program implementers have been formulated. Several official institutions can aid spring protection management. Together with water users and forest area managers, all institutions agreed to carry out activities to protect and conserve springs and springshed areas.

Abstract
Climate change is a major factor affecting hydrologic processes, water resources and agricultural productions in a catchment. This study aimed to evaluate the historical trends, future climate changes, characteristics of heat waves, dry and wet months in Bilate catchment, southern Ethiopia. The Mann-Kendal, Theil-Sen estimator were employed to analyse the trends and magnitude of trends of historical temperature and rainfall. Ensemble mean of regional climate models (RCMs) was employed for the future climate projections of this (2021-2050), mid (2051-2070), and end (2081-2100) centuries relative to baseline (1981-2010). Results revealed that the change in temperature under RCP4.5 and RCP8.5 showed an increase in the three future periods. Under the scenarios, the monthly maximum temperature is projected to increase in the range of 0.1 to 2.4 °C and 0.1 to 4.2 °C, respectively. Likewise, the minimum temperature is in the range of 0.1 to 1.9°C and 0.3 to 3.5 °C. Under the scenarios, seasonal rainfall is projected to increase in the range of 124 to 3,009.9 mm and 52.5 to 1111.0 mm; while decreases are from -19.4 to -1679.3 and -243.3 to -2,444.7 mm, respectively. Besides, dry months and heat waves are expected to increase. The combined effect of a reduction in rainfall, increase in heat waves and dry months will likely impact on the people whose livelihood depend on rain-fed subsistence agriculture in the catchment. Water and crop yield reduction are the major implications in this century. These findings raise awareness about the impacts of climate change in the community and regional authorities to endorse development policies.

Abstract
Climate change is a major concern for the environmental, social and economic sectors of our world. The purpose of the study was to examine climate variability and trends in East Wollega Zone, Western Ethiopia. Daily precipitation and temperature information for 37 years (1981-2017) were gathered from the Ethiopian National Meteorological Agency. Mann-Kendall trend test, Sen Slope, linear regression model, and coefficient of variation were used to analyze data. The result found that monthly, seasonal and annual rainfall observed an insignificant declining trend except for May, November, and spring and the change was only significant for August at a significance level of 0.05. Maximum and minimum temperature revealed upward warming trends on a monthly, seasonal and yearly basis. The outcome of the linear regression model indicated an insignificant relationship between monthly, seasonal, and annual rainfall and time at a confidence level of 0.05. A statistically significant relationship has been detected between annual maximum, minimum, and mean temperature and year at 0.05 significance level. With the exception of winter minimum temperature, the result found a statistically significant relationship for seasonal temperature. The variation of seasonal rainfall was moderate for summer (23%) and autumn (29%) while it was high for spring (33%) and winter (65%) and it was also moderate for annual (23%). In view of the fact that crop production is affected by rainfall and temperature variability, adaptation to its adverse effect is imperative. Cropping system decisions and adaptation plans in the area should better accommodate for fluctuations in rainfall and temperature.

Published: April 2022

Abstract
Climate change in Indonesia, including erratic rainfall intensity, extreme temperatures, El Nino and La Nina events, can cause farmers not to implement agricultural efforts optimally. Multiplier effect caused is the risk of decreased agricultural production and even crop failure that causes losses for farmers. The impact can broadly reduce farmers’ welfare, food security and increase poverty, for which most Indonesians livelihood as farmers. The negative consequences of climate change require efforts to minimize the impact and anticipate through adaptation strategies. These research aims are to analyze the impact of climate change on the agriculture sector and develop an adaptation strategy to address the impact of climate change on the agricultural sector. This method uses review literature related to the impact of climate change on agricultural products and adaptation strategies to climate change in the agricultural sector. The impact of climate change caused a decline in agricultural production and even crop failure. The main actors of climate change that affect the agricultural sector include rain patterns, extreme climate events (floods and droughts), and increased air temperatures. Recommendations for adaptation strategies are using superior plants, adjusting planting time and pattern, water management technology (rain harvesting and irrigation), and biotic environmental strategies.

Abstract
In general, there is a gap between people’s subjective and objective assessment of risk and resilience and objective resilience is larger than a subjective one. The aim of this paper is to analyze farmers’ perception of climate change comparing with objective data. We conducted the questionnaire survey in Khon Kaen Province in Northeast Thailand and clarified the farmers’ profile, agricultural management, and perception of climate change. In addition, comparing to questionnaire result and objective data, we discussed how much the actual farmers’ perception of climate change is different from the objective data. As a result, the farmers perceptions to the rainfall amount in 10 years and trend of objective data were not consistent. This gap suggests that farmers perceived changes in short-term rainfall as climate change rather than changes in long-term rainfall, and that farmers may perceive their production as decreasing due to the increased amount lost due to the expansion of paddy fields into unsuitable areas.

Published: April 2022

Abstract
The purpose of this article was to examine the influence of ownership structure, environmental performance, financial performance, and company size on carbon emissions reporting of high profile companies in Indonesia. Ownership structure was measured by foreign ownership, institutional ownership, and concentrated ownership, while environmental performance was measured by the Company Performance Rating Program in Environmental Management released by the Ministry of Environment (PROPER) and ISO 14001 certification. The disclosure of carbon emissions was assessed by an index drawn from the carbon disclosures project (CDP). High profiles companies were chosen as the sample since the companies create carbon emissions in their operation which contributes to global climate change. Utilizing 102 companies in 2019 as a sample, results of multivariate regression suggest that institutional ownership and size positively influence the level of carbon emission disclosure. These results indicate that larger companies and companies owned by an institution have a higher tendency to report carbon emissions either in the firm’s annual report or in the sustainability reporting. The findings motivated the listed companies in reporting their carbon emission which is voluntary in nature. Such findings may give an understanding to the capital market regulatory body in releasing regulations that encourage listed companies to report their carbon emission.
The effect of indigenous vegetations on the biological control of oil palm basal stem rot (BSR) disease caused by Ganoderma in peatlands

Abstract
Oil palm is an important plantation commodity in Indonesia. Oil palm cultivation in Indonesia is always associated with global warming because some of its plantation’s areas are on peatlands and its management not yet environmentally friendly. A serious problem of oil palm cultivation on peatlands is the basal stem rot disease caused by the Ganoderma fungi. There is no effective method to control this disease. Biological control is an alternative method that is environmentally friendly and is the focus of current development, however, in peatland, its development was limited by the lack of information about the influence of peat environmental factors. This study aims to determine the effect of indigenous vegetation on the biological control of Ganoderma on oil palm on peat soil. The research has been conducted by examining the effect of 4 species of peat indigenous plants on the effectiveness of Ganoderma biological control on peat soil in the experimental garden. The results showed that the presence of peat indigenous plants affected the effectiveness of Ganoderma control in oil palm on West Kalimantan peat soils. The single indigenous plant Nephrolepis biserrata was able to reduce the intensity of the disease. However, the use of mixed indigenous plants N. biserrata, Asystasia intrusa, Melastoma affine, and Stenochlaena palustris actually increased the intensity of the disease. These results indicate that the management of existing peat indigenous vegetations around oil palm plantations can help reduce the Ganoderma attacks on oil palm on peat soils.
