Heterogeneous impacts of climate change on crop yields across altitudes in Ethiopia

Impacts of climate change can differ from one region to another. We combine the household-level panel data with weather and climate data to examine the heterogeneity of the impacts of climate change on crop yields across different crops and agro-ecologies in Ethiopia. Our results show that climate change will induce an increase in coffee and teff yields by 31% and 8.3%, respectively, at high altitudes by the years 2041-2060 compared to 1988-2018, under a medium emissions scenario. Conversely, it will reduce coffee yield by 3% at low altitudes, and barley, maize, and wheat yield by 22.7%, 48%, and 10%, respectively, at high altitudes. These findings suggest that tailoring agricultural development programs and climate adaptation strategies to address location and crop-specific sensitivity to climate change may help to build resilience and improve the livelihood of smallholder farmers

Effectiveness of Climate Change Adaptation Strategies: Household-Level Evidence from Ethiopia

In response to climate change and variability, farmers use various adaptation strategies. This study examines theeffectiveness of those adaptation strategies in ensuring farmers’ food security in rural villages of Boricha fromsouthern Ethiopia. In addition to data obtained from meteorological stations, cross-sectional data is collectedinterviewing 208 farm households. Analyses show that there is climate change and variability in the area andhousehold adapt using various strategies. Two-Stage Least Square estimation results reveal that rainfall andtemperature variability have negative impact on household’s food security. Moreover, results confirmeffectiveness of climate adaptation strategies namely soil and water conservation, modern varieties and cropdiversification in mitigating climatic risks and ensuring household food security. Results also indicate thateducation, agricultural extension, access to market and credit are key factors enhancing adaptation decisions.Consequently, programs that augment households’ climate awareness and adaptation decision could helpreducing risks pertaining to climate.Keywords: Climate change and variability, adaptation strategies, household food security, Two-Stage LeastSquare, Boricha, Sidama, Ethiopi

Intra-household risk perceptions and climate change adaptation in sub-Saharan Africa

We examine the effects of spouses' climate risk perceptions (CRPs), defined by their beliefs about unfavourable climatic events and associated damages, on climate change adaptation (CCA) and the observed gender gap in adaptation. Our analysis uses the intra-household data collected by independent interviews with 1,274 female and male spouses in Kenya, Uganda and Senegal. By addressing the CRP endogeneity issue using the exogenous weather shocks during data collection months as instruments, we find that a higher CRP of both female and male spouses increases their probability of adopting CCA strategies. We also find that a higher CRP of female spouses reduces the adaptation gap by increasing their relative adoption of soil and water conservation practices. Our results highlight the importance of understanding gender-differentiated behavioural and economic factors to design effective climate policy interventions

Sustainable protected areas: Synergies between biodiversity conservation and socioeconomic development

1. Reconciling conservation and socioeconomic development goals is key to sustainability but remains a source of fierce debate. Protected areas (PAs) are believed to play an essential role in achieving these seemingly conflicting goals. Yet, there is limited evidence as to whether PAs are actually achieving the two goals simultaneously. 2. Here, we investigate when and to what extent synergies or trade‐offs between biodiversity conservation and local socioeconomic development occur. To explore these relationships, we collected data across a wide range of socioeconomic settings through face‐to‐face survey with PA managers from 114 African and European PAs using structured questionnaire. 3. We found synergies between biodiversity conservation and socioeconomic development for 62% of the PAs, albeit with significant differences between African (55%) and European PAs (75%). Moreover, the sustainability of PAs in conserving biodiversity was strongly correlated with the empowerment of the PA management and the involvement of local communities in PA planning and decision‐making processes. 4. Our results demonstrate that for PAs to promote synergies between biodiversity conservation and local socioeconomic development, and to enhance their long‐term sustainability, they should invest in the empowerment of their respective management and involvement of local communities in their planning and management activities

The Use of Swear Words by Junior High School Students 1 at Kotabaru Karawang West Java

Dalam setiap bahasa terdapat kata-kata yang dianggap tidak sopan untuk dikatakan kepada lawan bicara. Kata-kata tersebut mengacu kepada kata-kata yang mengandung makian dan sumpah serapah, serta memiliki konotasi kasar dan tabu untuk diucapkan dalam situasi formal. Dalam era globalisasi ini, banyak remaja khususnya remaja Sekolah menengah Pertama yang menggunakan umpatan dalam komunikasi mereka sehari-hari. Oleh karena itu, penulis tergugah untuk menganalisis fenomena penggunaan kata umpatan oleh siswa SMPN 1 di wilayah Kotabaru Karawang. Tujuan dari penelitian ini adalah untuk menunjukkan dan menganalisis penggunaan kata umpatan yang digunakan oleh siswa SMP mengacu kepada teori Sosiolinguistik yang dikemukakan oleh Janet Holmes. Kata-kata umpatan yang diproduksi oleh siswa merupakan penelitian yang bersifat deskriptif dengan pendekatan kualitatif. Penulis mengambil data dengan teknik purposive sampling sehingga penulis mendapat data sebanyak 25 kata umpatan yang dalam pengumpulan datanya dibagi menjadi 2 tahap yaitu wawancara dan observasi. Penulis juga menggunakan teknik Simak Bebas Libat Cakap dan teknik catat ketika mengobservasi tuturan umpatan yang digunakan oleh siswa. Dalam mewawancarai siswa, penulis menggunakan teknik rekam untuk menjaga keaslian data. Dari hasil pengumpulan data, penulis mendapatkan 16 tuturan umpatan yang diperoleh dengan cara mewawancarai siswa dan 9 tuturan umpatan yang diperoleh dengan cara observasi di sekolah. Sebagian besar kata – kata umpatan dituturkan oleh siswa laki – laki. Namun ada beberapa tuturan umpatan yang diproduksi oleh siswa perempuan ketika mengumpat dengan teman sebayanya. Dari hasil observasi, penulis menemukan kata – kata umpatan yang digunakan siswa kepada temannya hanya pada latar informal. Walaupun ada seorang murid yang mengaku bahwa dirinya pernah mengumpat pada saat terdapat guru di dalam kelas, hal itu tidak lebih dari sekedar lelucon belaka. Secara garis besar, topik ketika siswa mengumpat kepada temannya hanya sebagai bahan lelucon. Meskipun ada beberapa tuturan umpatan yang mempunyai topik kemarahan, sebagian besar umpatan yang digunakan siswa mempunyai fungsi ekspresif

Analysis of differences and commonalities in wildlife hunting across the Africa-Europe South-North gradient

Hunting and its impacts on wildlife are typically studied regionally, with a particular focus on the Global South. Hunting can, however, also undermine rewilding efforts or threaten wildlife in the Global North. Little is known about how hunting manifests under varying socioeconomic and ecological contexts across the Global South and North. Herein, we examined differences and commonalities in hunting characteristics across an exemplary Global South-North gradient approximated by the Human Development Index (HDI) using face-to-face interviews with 114 protected area (PA) managers in 25 African and European countries. Generally, we observed that hunting ranges from the illegal, economically motivated, and unsustainable hunting of herbivores in the South to the legal, socially and ecologically motivated hunting of ungulates within parks and the illegal hunting of mainly predators outside parks in the North. Commonalities across this Africa-Europe South-North gradient included increased conflict-related killings in human-dominated landscapes and decreased illegal hunting with beneficial community conditions, such as mutual trust resulting from community involvement in PA management. Nevertheless, local conditions cannot outweigh the strong effect of the HDI on unsustainable hunting. Our findings highlight regional challenges that require collaborative, integrative efforts in wildlife conservation across actors, while identified commonalities may outline universal mechanisms for achieving this goal.publishedVersio

Essays on heterogeneity and uncertainty in climate policy and development

This thesis consists of four papers focusing on the role of heterogeneity and uncertainty in the context of climate change policy and agricultural development. By using intra-household data, the first paper illustrates differences in spouses’ perception of climatic risks and its effect on household’s adoption of climate change adaptation in sub-Saharan Africa. In Kenya, female spouses’ perception of climatic risks increases the household’s likelihood of adopting climate adaptation strategies, whereas males’ perception has no statistically significant effects. The adoption of livestock-based strategies for climate change adaptation is positively associated with both female and male spouses’ perceptions of climatic risks in Uganda, whereas it has a negative relationship with females’ perception in Tanzania. Moreover, both male and female spouses’ perceptions of climatic risks have positive associations with households’ likelihood of adopting crop-based strategies for climate change adaptation in Uganda and Tanzania. The second paper assesses how the impacts of climate change vary across crops and across agro-ecosystems in Ethiopia using the household-level panel data. The empirical results show that climate change will induce an increase in coffee and teff yields at high altitudes while it will decrease coffee yield at low altitudes, and barley, maize, and wheat yield at high altitudes by the years 2041-2060. The third paper provides a systematic review of literature that uses a real-options approach for the analysis of investment in climate adaptation and mitigation actions. The review shows the need of future research incorporating climate uncertainty, risk preferences, and decisions-makers’ strategic interactions. The fourth paper models farmers’ opportunity to relocate coffee farms to higher altitudes in Ethiopia as climate adaptation strategy. The results illustrate how the uncertainty in net returns and high establishment costs may induce farmers to postpone their adaptation actions. The findings of papers presented in this thesis point to the need to take into account the differences in individual behaviours, vulnerabilities and uncertainties in designing climate and development policies

Investing in climate change adaptation and mitigation: A methodological review of real-options studies

Uncertain future payoffs and irreversible costs characterize investment in climate change adaptation and mitigation. Under these conditions, it is relevant to analyze investment decisions in a real options framework, as this approach takes into account the economic value associated with investment time flexibility. In this paper, we provide an overview of the literature adopting a real option approach to analyze investment in climate change adaptation and mitigation, and examine how the uncertain impacts of climate change on the condition of the human environment, risk preferences, and strategic interactions among decisions-makers have been modeled. We found that the complex nature of uncertainties associated with climate change is typically only partially taken into account and that the analysis is usually limited to decisions taken by individual risk neutral profit maximizers. Our findings call for further research to fill the identified gaps

What does community participation in nature protection mean? The case of tropical national parks in Africa

International audienceIn spite of significant investment, community-based conservation often suffers from a lack of appropriate design. In this study, drawing on 86 interviews around six national parks in tropical Africa, we analyse the perceptions of different stakeholders (e.g. governmental officials, non-governmental organization staff and researchers) regarding community participation. Our results mainly reveal the absence of a clear and shared definition of community participation. While 67% of the participants defined community participation as a community's support of nature protection (low empowerment) and/or as its participation in conservation implementation (medium empowerment), 28% mentioned that the community should also participate in decision-making (high empowerment). Our study shows that participants with no university degree, belonging to governmental organizations and/or employed as workers tend to propose a lower level of empowerment, while those educated to a postgraduate level, belonging to research institutes and/or employed as researchers propose higher degrees of empowerment. Our study mainly suggests that the different degrees of empowerment proposed by the stakeholders depend on their relation to the space of conservation and their daily connection to practical management as drivers of the inclusion or exclusion of local communities in conservation decision-making. To properly design and implement community-based conservation, conservation actors above all must share a common definition of the concept
