Between heavy rain and sea level rise

This manual is a product of the Climate Resilient Agriculture Investigation and Innovation project (CRAIIP). It presents the Climate Field Lab approach and provides tools for climate change adaptation by smallholder farmers in two rural regions in Indonesia. The Climate Field Lab adheres to transdisciplinary adaptation co-research through a science-practice partnership on agroecological farming. Co-research implies that farmers are local experts in cooperating actively with nature and its weather variability. Alas, the impacts of climate change aggravate farming through the increased frequency and magnitude of climate-related extremes. As a consequence, farmers are faced with the continuous need to build their adaptive capacities through co-creation of knowledge in a dialogue with their communities, with scientists and with climate change experts. Between 2016 and 2019, the Indonesian-German CRAIIP team consisting of co-research farmers, two farmers’ organisations/NGOs, as well as scientists of three universities, applied various cocreation tools for building the adaptive capacity in Climate Field Labs in two regions. An estimated 100 smallholder farmers, women and men, from West and Central Java and South Sulawesi took part in the solution-oriented research. This manual is directed towards scholars, students, trainers and development experts. It offers a set of instruments that aim at broadening their spectrum for approaches, methods and tools of participatory adaptation co-research, directed towards their own research and development work. All tools presented in this handbook were tested in farmerled research processes, which included demonstrations on stress-resilient rice varieties, improved agro-ecological soil fertility strategies in rice, and the organic cultivation of local chilli pepper varieties. The manual starts with the climate change situation in Indonesia (part 2). The concept for cocreation of knowledge in the Climate Field Lab is explained in part 3. Part 4 presents the 18 tools used in the Climate Field Lab illustrated by examples, useful materials and numerous practical tips applicable for own adaptation co-research. Part 5 includes the annexes, provides an overview of all information and training materials, as well as including scientific articles produced throughout the course of the project CRAIIP. The CRAIIP partners wish to get in touch with other science-practice networks to help to build climate resilience of smallholder farmers through co-creation of knowledge, agro-ecological approaches and to advocate and spread the use of adaptation co-research as a research method

The Role of Indigenous Vegetables to Improve Food and Nutrition Security: Experiences From the Project HORTINLEA in Kenya (2014–2018)

Many warning signs indicate that the food security goals formulated in 2015 will not be achieved. This situation is particularly true for the African continent. After substantial progress up to 2015, the situation has hardly improved or has worsened in many respects. In addition to the rapid population growth, the increasingly frequent long dry periods or sometimes erratic rainfall have contributed to this. In addition, current production systems have dysfunctional side effects due to increasing yield optimization and specialization. Thus, besides the associated resource degradation, it also leads to a monotonous food supply and the emergence of vitamin and mineral deficiencies (hidden hunger). A meaningful way to diversify the food supply is to cultivate and market previously underutilized species. However, they are characterized by not being known and traded globally and usually having only local importance. Accordingly, they have been widely ignored in research. Increasingly, however, there is a growing realization worldwide that these plants can make an essential contribution to food and nutrition security, especially for poorer segments of the population. Moreover, they are adapted to local conditions and are often produced with less resource input. This article aims to show how these species can be better utilized to provide nutritious food through sustainable production, using the example of African indigenous vegetables. In doing so, the impact of emerging social and ecological changes in Kenya will be considered. This source is an interdisciplinary collaborative research project, Horticultural Innovation and Learning for Improved Nutrition and Livelihood in East Africa (HORTINLEA), which was carried out in Kenya from 2014 to 2018. Many different disciplines were involved in the German-African cooperation project. The results will be brought together in this article with the help of a food-sensitive value chain approach, and the experiences gained from this project will be reflected.Peer Reviewe

Understanding adaptive capacity of smallholder African indigenous vegetable farmers to climate change in Kenya

Understanding the adaptive capacity (AC) of farmers is crucial to planning effective adaptation. Action to promote farmers’ AC is required because climate change (CC) is resulting in unpredictable alterations in weather patterns. Based on the sustainable livelihoods framework (SLF), this study explored how access to natural, physical, financial, social and human capitals enhances the AC. Quantitative data from 269 African indigenous vegetable (AIV) farmers in three selected agro-climatic zones in Kenya were analysed. Four indicators in each capital were selected based on previous studies and judgments collected from an expert online ranking survey (n = 35). The Kruskal-Wallis H test and an independent sample t-test were used to test the independence of AC scores and access to the different resources. The findings showed that the majority of farmers (53%) had a moderate AC, while fewer (32%) and (15%) had low or high AC levels respectively. Disparities in adaptive capacity scores were recorded between respondents in terms of their age, marital status and location. Farmers had high access to social capital but low access to financial, natural and human capitals. Female farmers showed lower capacities in the areas of financial, human and natural resources, while their male counterparts had low access to some human and social capitals. Resilient interventions that target individuals with low adaptive capacities are required. © 2020 The Author

Drivers of sustainable intensification in Kenyan rural and peri-urban vegetable production

Sustainable intensification promotes environmentally sound and productive agriculture. However, use of sustainable intensification practices (SIPs) is low in many sub-Sharan African countries. This study examined the adoption of SIPs in Kenyan rural and peri-urban vegetable production to understand the scale of and underlying factors in the use of SIPs. A multistage sampling technique was employed to randomly select 685 rural and peri-urban vegetable farm households. Household data was then collected and anaylsed for four practices namely improved irrigation, integrated soil fertility, organic manure and crop diversification using a pre-tested structured questionnaire. A multivariate probit model was run to model simultaneous interdependent adoption decisions. Adoption of organic manure and African indigenous vegetables (AIV) diversification was high in both rural and peri-urban areas. However, adoption of improved irrigation systems and integrated soil fertility management was low, and even significantly lower in rural areas than in peri-urban areas (p < 0.041). Similarly, adoption intensity of SIPs was lower in rural areas than in peri-urban areas. Furthermore, the findings also show complementarities and substitutabilities between SIPs. Market integration, the farm location and household income were the major factors heavily influencing the adoption of most SIPs. Policies and programmes that seek to build household financial capital base and integrate farm households into effective and efficient vegetable markets need to be formulated and implemented in order to enhance adoption of SIPs in AIV production

Farmers’ perspectives: Impact of climate change on African indigenous vegetable production in Kenya

Purpose - Understanding farmers’ perceptions of how the climate is changing is vital to anticipating its impacts. Farmers are known to take appropriate steps to adapt only when they perceive change to be taking place. This study aims to analyse how African indigenous vegetable (AIV) farmers perceive climate change in three different agro-climatic zones (ACZs) in Kenya, identify the main differences in historical seasonal and annual rainfall and temperature trends between the zones, discuss differences in farmers’ perceptions and historical trends and analyse the impact of these perceived changes and trends on yields, weeds, pests and disease infestation of AIVs. Design/methodology/approach - Data collection was undertaken in focus group discussions (FGD) (N = 211) and during interviews with individual farmers (N = 269). The Mann–Kendall test and regression were applied for trend analysis of time series data (1980-2014). Analysis of variance and least significant difference were used to test for differences in mean rainfall data, while a chi-square test examined the association between farmer perceptions and ACZs. Coefficient of variation expressed as a percentage was used to show variability in mean annual and seasonal rainfall between the zones. Findings - Farmers perceived that higher temperatures, decreased rainfall, late onset and early retreat of rain, erratic rainfall patterns and frequent dry spells were increasing the incidences of droughts and floods. The chi-square results showed a significant relationship between some of these perceptions and ACZs. Meteorological data provided some evidence to support farmers’ perceptions of changing rainfall. No trend was detected in mean annual rainfall, but a significant increase was recorded in the semi-humid zone. A decreasing maximum temperature was noted in the semi-humid zone, but otherwise, an overall increase was detected. There were highly significant differences in mean annual rainfall between the zones. Farmers perceived reduced yields and changes in pest infestation and diseases in some AIVs to be prevalent in the dry season. This study’s findings provide a basis for local and timely institutional changes, which could certainly help in reducing the adverse effects of climate change. Originality/value - This is an original research paper and the historical trends, farmers’ perceptions and effects of climate change on AIV production documented in this paper may also be representative of other ACZs in Kenya

Growing and Eating Food during the COVID-19 Pandemic:Farmers’ Perspectives on Local Food System Resilience to Shocks in Southern Africa and Indonesia

The COVID-19 outbreak forced governments to make decisions that had adverse effects on local food systems and supply chains. As a result, many small-scale food producers faced difficulties growing, harvesting, and selling their goods. This participatory research examines local small-scale farmers’ challenges as farmers but also as consumers and their coping strategies during the month of April and one week in June 2020. The study was initiated and conceptualized in collaboration with small-scale farmer members of an existing research network in selected urban and rural areas in South Africa, Mozambique, Zimbabwe, and Indonesia. Participants co-designed the research, collected and uploaded data through digital survey tools, and contributed to data analysis and interpretation. A common observation across regions is that the measures imposed in response to COVID-19 highlighted and partly exacerbated existing socio-economic inequalities among food system actors. Strict lockdowns in Cape Town, South Africa, and Masvingo, Zimbabwe, significantly restricted the production capacity of small-scale farmers in the informal economy and created more foodinsecurityforthem. InMaputo,Mozambique,andTorajaandJava,Indonesia,localfoodsystems continued to operate and were even strengthened by higher social capital and adaptive capacities

The Role of Rumination and Reduced Concreteness in the Maintenance of Posttraumatic Stress Disorder and Depression Following Trauma

Rumination has been linked to posttraumatic stress disorder (PTSD) and depression following trauma. A cross-sectional (N = 101) and a prospective longitudinal study (N = 147) of road traffic accident survivors assessed rumination, PTSD and depression with self-report measures and structured interviews. We tested the hypotheses that (1) rumination predicts the maintenance of PTSD and depression and (2) reduced concreteness of ruminative thinking may be a maintaining factor. Rumination significantly predicted PTSD and depression at 6 months over and above what could be predicted from initial symptom levels. In contrast to the second hypothesis, reduced concreteness in an iterative rumination task was not significantly correlated with self-reported rumination frequency, and did not consistently correlate with symptom severity measures. However, multiple regression analyses showed that the combination of reduced concreteness and self-reported frequency of rumination predicted subsequent PTSD better than rumination frequency alone. The results support the view that rumination is an important maintaining factor of trauma-related emotional disorders

Smallholder Farmers’ Challenges of Coping with COVID-19 Containments: Insights from two food regions in Indonesia

The COVID-19 pandemic has forced governments around the world to impose containment measures to prevent the rapid spread of the corona virus. The Indonesian government implemented “large-scale social restrictions,” which have impacted farming and farmers’ food security. Farmers are both producers and consumers of food and, therefore, have been facing new challenges due to transport restrictions, price spikes for inputs, price drops for their produce, or conditions which aggravated cooperation, such as social distancing. This study aims at analysing the challenges of the containments from a smallholder farmer perspective and examining farmers’ coping potential. A digital survey with 323 farmers has been designed as comparative observational research in Toraja, South Sulawesi, and selected regions of Java. The Bonferroni Multiple Comparison Test was used to test for significance regarding socioeconomic factors and space. A logistic regression model extracted determinants for crisis coping. Results reveal, that female farmers worry more about COVID-19 outbreak compared to men at a significant level. In contrast, male farmers, particularly in Java, are more concerned about social restrictions due to limited mobility. Food price spikes were reported in both regions, with sharp increases for fish, fruits, and vegetables in Java, for staples in Toraja, and for meat and sugar in both regions. Food groups, that trade through agents and brokers or are transported longer distances were affected most due to their complex and long supply chains that were disrupted during the restrictions. In Java, farmers face multiple shocks, of which climate change was reported even more often than the pandemic related shocks. Not being able to help each other on the farm due to social distancing is a significant concern of farmers in Toraja. As a result of food market disturbances, farmers began to grow and eat more vegetables and fruits. In conclusion, food security for farmers slightly decreased due to affordability, and market disruptions already point to long-term income losses. The study team recommends to promote smallholders’ healthy food production, value addition and direct end-consumer linkages to build back better their livelihoods post- COVID-19.Peer Reviewe

Improving the Climate Resilience of Rice Farming in Flood-Prone Areas through Azolla Biofertilizer and Saline-Tolerant Varieties

Rice farming in coastal areas is often victim to flooding as a result of climate change. Low-cost adaptation strategies are required to increase resilience and rice productivity in these flood-prone coastal areas. In this study, enriched Azolla extract (EAE) liquid biofertilizers, combined with selected stress-tolerant rice varieties, were tested in farmers’ fields in Pangandaran, West Java from June to October 2020. This study aimed to investigate the effectiveness of EAE in increasing the yield of different rice varieties. The research was arranged as a split-plot design with five replications. The main plot was the EAE application (T1 = 3 ton ha−1 compost and T2 = 3 ton ha−1 compost + 10 L ha−1 of EAE), and the sub-plots were stress-tolerant rice varieties (V1 = Inpari 43, V2 = Mawar, V3 = Inpari 30, V4 = Inpara 03, V5 = Mendawak). The application of EAE of 10 L ha−1 significantly affected the rice grain yield, which was 37.06% higher than that of the control plot. The average grain yield of the five varieties under EAE treatment (5.51 ton ha−1) was greater than the grain yield of local farmers’ fields (3.78−4.97 ton ha−1). Inpari 43 had the highest grain yield with 5.90 ton ha−1, but the yield was not significantly different from the Mendawak variety (4.90 ton ha−1). This result suggests that EAE and selected stress-tolerant rice varieties (Inpari 43 or Mendawak) are an effective adaptation strategy to increase rice farms’ resilience and productivity in coastal areas prone to flooding.Peer Reviewe
