Strengthening climate resilience of rural communities by co-producing landscape-specific integrated farming systems in Cambodia

Climate change poses a major threat to the livelihoods of rural smallholder farmers in Cambodia. Adaptation measures through sustainable land management (SLM) and farming practices can help farmers to increase their resilience to climate change and secure their livelihoods. This paper presents a novel approach for promoting landscape-specific integrated farming systems (IFS) through multi-stakeholder engagement, knowledge-based decision-making and improved land use planning. It presents a stepwise participatory approach, applied under an IFAD-funded project, to define context-specific IFS models. Through co-production processes with multiple stakeholders, three landscape units and seven landscape-specific IFS models consisting of different SLM technologies were defined and demonstrated on 1,500 farms in two case study sites. The process included training and awareness raising to enhance local stakeholder engagement in developing integrated farm plans. This paper provides insights into how such a novel approach can be embedded in rural development projects to enhance smallholders’ resilience and livelihoods

Pathways from research to sustainable development: insights from ten research projects in sustainability and resilience

Drawing on collective experience from ten collaborative research projects focused on the Global South, we identify three major challenges that impede the translation of research on sustainability and resilience into better-informed choices by individuals and policy-makers that in turn can support transformation to a sustainable future. The three challenges comprise: (i) converting knowledge produced during research projects into successful knowledge application; (ii) scaling up knowledge in time when research projects are short-term and potential impacts are long-term; and (iii) scaling up knowledge across space, from local research sites to larger-scale or even global impact. Some potential pathways for funding agencies to overcome these challenges include providing targeted prolonged funding for dissemination and outreach, and facilitating collaboration and coordination across different sites, research teams, and partner organizations. By systematically documenting these challenges, we hope to pave the way for further innovations in the research cycle

Educational Trials to Quantify Agronomic Information in Interdisciplinary Fieldwork in Pursat Province, Cambodia

Improving agricultural research and education is highly recommended to control agricultural development and environmental sustainability in Cambodia. Agricultural research mostly focuses on interviews with farmers as a first measure in developing countries, but a lack of quantitative accuracy remains one of the major constraints. In this situation, we conducted educational activities for master’s degree students of the Royal University of Agriculture (RUA) to append agronomic information with popular equipment in interdisciplinary fieldwork in Pursat Province, Cambodia. For the popular equipment, an RGB camera, a reflectometer as well as pH and EC meters were selected. The agronomic information collected by the students supported the results obtained during the interviews. For example, the difference in fertilizer application between the irrigated and nonirrigated areas was confirmed by the soil ammonium concentration evaluated with a reflectometer; the difference in rice growth among water conditions was confirmed by the leaf area percentage evaluated with an RGB camera. Since the majority of the students lacked agricultural and statistical knowledge, the agronomic information quantified by popular equipment provided proper educational materials. The interdisciplinary fieldwork also indicated serious problems in the study area, such as low beneficial crop production and environmental sustainability. To overcome these problems, improving agricultural education is required to foster skillful agricultural professionals, and the quantification of agronomic information is an essential issue

Teaching Manual for for Bachelor’s and Master’s courses on Sustainable Development and Sustainable Land Management at the Royal University of Cambodia

Purpose of this teaching manual This teaching manual was developed to enable lecturers at the Royal University of Agriculture (RUA) and agriculture-focused higher education institutions in Cambodia to deliver a course on Sustainable Development and Sustainable Land Management for Bachelor’s and Master’s students. The structure of the course was jointly developed by the RUA and the Centre for Development and Environment (CDE) of the University of Bern, Switzerland, based on the requirements of the RUA. The teaching manual aims to provide lecturers with an increased understanding of Education for Sustainable Development (ESD) and skills to implement ESD at the university and other higher education institutions. The lectures will deliver the content of sustainable development and sustainable land management through ESD-oriented teaching. This will capacitate the lecturers to establish good quality tertiary education with a focus on ESD. Students will be well trained in sustainability issues with a view to contributing to sustainable development and to the sustainable use of natural resources in their country. The students will be able to address today’s challenges of food security, climate change, resource degradation, and poverty

The impacts of degradation, deforestation and restoration on mangrove ecosystem carbon stocks across Cambodia

Mangrove forest conservation can help reduce global C emissions. Despite this benefit to climate change mitigation and adaptation, mangrove forests are being deforested or degraded at an alarming rate, though restoration efforts may offset these losses. The impacts of deforestation to C stocks are relatively intuitive and result in significant decreases in C stocks. It remains unclear how degradation from selective harvesting of trees affects C stocks or how effective restoration efforts are at restoring C stocks. Furthermore, total ecosystem C (TEC) stocks of pristine mangroves can significantly vary spatially. To address these issues, we conducted an intensive, national assessment of mangrove forests across Cambodia using a grid approach to: 1) examine how land use land cover (i.e., pristine, deforested, degraded, and restored forests) impacts TEC stocks, and 2) how TEC stocks vary spatially across the country. TEC stocks from deforested mangroves were always lower than pristine forests, resulting in an overall loss of 60% C (480 Mg C ha−1). However, TEC stocks from degraded and 25-year-old restored mangroves forests did not differ from pristine forests. Mean TEC in mangroves was 784.7 ± 30.1 Mg C ha−1, decreasing from 957.2 ± 32.8 Mg C ha−1 in the northern region to 628.9 ± 33.1 Mg C ha−1 in the central region to 386.2 ± 19.1 Mg C ha−1 in the southern region of Cambodia. Intensive sampling in mangroves across Cambodia verified impacts of deforestation reported elsewhere, revealed the lack of degradation impacts on TEC stocks, and demonstrated the effectiveness of restoration on TEC stocks after only 25 years. Our gridded sampling approach was able to capture spatial variability across Cambodia and provide a more realistic TEC stock information that can be used for national reporting or participation in C markets

Does Shade Impact Coffee Yield, Tree Trunk, and Soil Moisture on <i>Coffea canephora</i> Plantations in Mondulkiri, Cambodia?

Shade is a natural condition for coffee plants; however, unshaded plantations currently predominate in Asia. The benefits of shading increase as the environment becomes less favorable for coffee cultivation, e.g., because of climate change. It is necessary to determine the effects of shade on the yield of Coffea canephora and on the soil water availability. Therefore, three coffee plantations (of 3, 6, and 9 ha) in the province of Mondulkiri, Cambodia, were selected to evaluate the effect of shade on Coffea canephora yields, coffee bush trunk changes, and soil moisture. Our study shows that shade-grown coffee delivers the same yields as coffee that is grown without shading in terms of coffee bean weight or size (comparing average values and bean variability), the total weight of coffee fruits per coffee shrub and the total weight of 100 fruits (fresh and dry). Additionally, fruit ripeness was not influenced by shade in terms of variability nor in terms of a possible delay in ripening. There was no difference in the coffee stem diameter changes between shaded and sunny sites, although the soil moisture was shown to be higher throughout the shaded sites

Discussing the possibility of extending the European vision of solid waste management to the Asian countries of Vietnam, Cambodia and Thailand

Waste management is a pressing global issue, especially in developing countries such as those in Southeast Asia. The lack of legal framework, technical skills, the not easy systematic management of the informal sector as well as the availability of adequate treatment facilities are among the main reasons for improper waste management. The literature has also shown the need to increase the awareness of citizens in waste magament. To address these problems, the European Union-funded SWAP (Sustainable solid WAste management and Policies) project aims to build capacity in waste management in Cambodia, Vietnam and Thailand through a mechanism that involves strengthening local universities. The benefits would affect the university and the entire supply chain such as students, lecturers, public and private companies as well as administrations. As SWAP indirectly emphasises the European model in waste management, this contribution addresses the possibility of extending to these countries the European vision in terms of Municipal Solid Waste (MSW) management system, focusing on technical, legal and informal actions. A brief assessment under a technical and environmental point of view of different treatment strategies regarding the waste management in these countries is also presented
