Its suitability for a wide range of crops has made agriculture one of the sub-region’s important economic sectors. It has also led to increased trade and investment linked to regional integration. More than two-thirds of the population of the countries comprising the Mekong Sub-region rely heavily on agriculture for their livelihoods (WWF Greater Mekong). These countries are Cambodia, the Lao People's Democratic Republic (Lao PDR), Myanmar, Thailand, and Vietnam. The People's Republic of China (Yunnan Province) is a part of this sub-region but for purposes of this forum is not included. The forum aimed to share research findings from SEARCA SFRT grantees across the Mekong Sub-Region, as well as develop research to address gaps, towards the promotion of ecological farming, adaptation to climate change, and improving rural livelihoods and food security. This forum covered Seed Fund for Research and Training (SFRT) research from 2013 to 2016 where 11 out of 15 studies of Vietnamese and Myanmar grantees are relevant to the above subject (none from Cambodia, Lao PDR, and Thailand for the period). The expected participants were selected local researchers from universities in Vietnam, particularly in the Mekong Delta, SFRT grantees and SEARCA Fellows/scholarship alumni from Cambodia, Lao PDR, Myanmar, Vietnam and Thailand. It also featured research conducted by the Research Center for Rural Development (RCRD) of An Giang University under the project component Agroecology Learning Alliance in South East Asia (ALiSEA).

Title of document: Presentations from the Laos Vegetable Forum 2017: Fostering a safe and sustainable vegetable sector Authors: Ministry/Government Agency/Organisation: CRS, KEI, NAFRI, ACIAR Year of publication: 2017 Geographic focus: Lao PDR Summary: In the Lao PDR, vegetable production provides around 80% of domestic demand, mostly produced by smallholder farmers. Throughout the country, there are large differences in consumption between provinces. Challenges to vegetable production include suboptimal yields, poor competitiveness, high postharvest losses, product that does not conform to quality and safety demands of consumers, limited technical capacity and difficulties in meeting market demand during some periods of the year. Additionally, the recent establishment of the ASEAN Economic Community has implications for cross-border trade regulations. Thus there are many opportunities for both producers and the private sector to benefit from improved connections and sustainability. The vegetable sector offers smallholder farmers an option to diversify their production systems and market opportunities, improve household nutrition and increase incomes for farmers and traders. Importantly, it also offers women a source of income, and can help improve household food security. As the sector develops, opportunities for market engagement, input supply and agro-processing will increase. These challenges and opportunities can be addressed in many different ways, and with a range of stakeholders. In Laos, there are public, private and development partners working to improve the productivity and profitability of the vegetable sector. Bringing these stakeholders together at a forum is a way to understand the current situation in Laos and create potential networks to foster sustainability in the sector. The Lao Vegetable Forum has been organized on 26th October, 2017 at the Crowne Plaza Hotel, Vientiane. The forum had several objectives, including to: - Highlight the latest research and development activities; - Forge networks between public, NGO and private sector professionals throughout the region working in this area for communication and collaboration; - Provide an opportunity to learn about developments in the region; and - Facilitate the exchange of ideas on sector development. In the first forum, the theme was ‘Fostering a safe and sustainable vegetable sector’. It started with an overview of the current status of the Lao Vegetable Sector. The main sessions focused on introducing different kinds of standards, and then options and examples of smallholder organisation and market arrangements. A final panel discussion was held to highlight the experiences of different kinds of stakeholders within the vegetable sector. Key themes that arised from the presentations and discussions will be synthesised and addressed in subsequent forums. Read More

Title of document: Better rice Initiative Asia Capacity Development for rice cultivation Authors: Henrik Beermann, Astari Widya Dharma Journal’s name if any: Ministry/Government Agency/Organisation: Deutsche Gesellschaft für Internationale Zusammenarbeit (GIZ) GmbH ; On behalf of The German Federal Ministry for Economic Cooperation and Development (BMZ) Year of publication: 2015 Geographic focus: ASIAN Main issues / topics addressed (for example: Capacity building strategy, technical processes of developing the CD strategies for sustainable rice cultivation,……) School of agroecology (if any): Web address to original document (if any): Summary: The German Food Partnership (GFP) aims at fostering the cooperation between private and public sector institutions. Its objective is to promote sustainable growth in agricultural production and improved access to nutrition within the food sector in emerging and developing countries. Public and private actors join forces in order to implement comprehensive projects and programs for sustainable business in these countries. The contribution towards food and nutrition security as well as economic development in rural areas is to be measured by increased agricultural productivity and income, improved availability of nutritious food, and food self-sufficiency. As one of the first concrete initiatives under the GFP umbrella, the Better Rice Initiative Asia (BRIA) is a joint project planned and implemented by private partners in collaboration with GIZ, and public organizations in the respective countries. BRIA aims at improving rice value chains (which include rice based nutrition components) in Southeast Asia (SEA), namely the four SEA countries Indonesia, the Philippines, Thailand, and Vietnam. BRIA’s focus is on strengthening the nutritional and economic situation of rice smallholders, and consumers. The purpose of this document is to provide an overview of the workshop and summarize the main lessons learned and recommendations for good practices of capacity development for sustainable rice cultivation in SEA.

Title of document: Dynamics of Soil Carbon, Nitrogen and Soil Respiration in Famer’s Field with Conservation Agriculture, Siem Reap, Cambodia Authors: Don Immanuel A. Edralin, Gilbert C. Sigua and Manuel R. Reyes Journal’s name if any: International Journal of Plant & Soil Science Ministry/Government Agency/Organisation: North Carolina Agricultural and Technical State University, Greensboro, NC, USA; United States Department of Agriculture, Agricultural Research Service, Coastal Plains Soil, Water, and Plant Research Center, Florence, SC, USA. Year of publication: 2016 Geographic focus: National level Main issues / topics addressed (for example: No tillage; conventional tillage; soil organic carbon; soil quality index; cover crops.…) School of agroecology (if any): Web address to original document (if any): Summary: The years of intensive tillage in many countries, including Cambodia have caused significant decline in agriculture’s natural resources that could threaten the future of agricultural production and sustainability worldwide. Long-term tillage system and site-specific crop management can affect changes in soil properties and processes, so there is a critical need for a better and comprehensive process-level understanding of differential effects of tillage systems and crop management on the direction and magnitude of changes in soil carbon storage and other soil properties. A study was conducted in farmer’s field to evaluate the effect of conservation agriculture (CA) and conventional tillage (CT) on soil carbon, nitrogen and soil respiration in three villages of Siem Reap, Cambodia. Soil organic carbon (p≤0.01), soil total nitrogen (p≤0.01) and soil respiration (p≤0.10) for at least in two villages were significantly affected by tillage management. The soil quality was improved in villages with CA compared with villages with CT by increasing soil organic carbon (10.2 to 13.3 Mg ha-1) and soil nitrogen (0.87 to 1.11 Mg ha-1) because of much higher soil moisture (15.7±8.6 to 20.0±11.9%) retained in CA and with reduced soil temperature (30.4±2.0 to 32.4±2.3°C) during the dry period. Additionally, field soil respiration was higher in CA (55.9±4.8 kg CO2-C ha-1 day-1) than in CT (36.2±13.5 kg CO2-C ha-1 day-1), which indicates more microbial activity and increased mineralization of soil organic carbon for nutrient release. The soil’s functions of supporting plant growth and sink of carbon and recycler of nutrients was likely improved in agroecosystem with CA than in system with CT. Our results have suggested that CA may have had enhanced soils’ carbon and nitrogen contents, nutrient supplying capacity and microclimate for soil microorganisms in three villages with vegetable production.

Title of document: Agroecology: A Global Paradigm to Challenge Mainstream Industrial Agriculture Authors: Hector Valenzuela Journal’s name if any: Ministry/Government Agency/Organisation: Department of Plant and Environmental Protection Sciences, University of Hawaii at Manoa, USA Year of publication: 2016 Geographic focus: Global level Main issues / topics addressed (for example: agroecology; agrobiodiversity; biodiversity; farming systems; organic farming; ecological farming; soil management, convention agriculture meet the basic sustainability criteria…) School of agroecology (if any): Web address to original document (if any): Summary: Considerable controversy continues to exist in scientific and policy circles about how to tackle issues of global hunger, malnutrition, and rural economic decline, as well as environmental issues, such as biodiversity loss and climate change adaptation. On the one hand, powerful vested interests, with close ties to government, media, and academic institutions, propose high-input technology-based solutions, speculative and neoliberal “market-based” solutions, and export-oriented agricultural models. On the other hand, an international scientific and grassroots Food Movement has emerged, calling for a redesign of the Global Food System in support of small-scale agroecological farming systems. A call to re-evaluate our current Food Systems was made in 2008 by the International Assessment of Agricultural Knowledge, Science and Technology for Development (IAASTD). Here, using the IAASTD study as a backdrop, we review the recent literature to outline key contentious points in the controversy between the need for high-input and “techno-based” versus agroecological farming models. A critical assessment is made of proposed strategies to protect soil resources, improve nutrient and energy cycles, protect agrobiodiversity, and promote social well-being in rural communities. With an increase in the number of affluent consumers (i.e., the middle class) in the developing world, and with the continued problem of extreme and chronic poverty with other larger sectors of society, Organic Farming and Agroecology models are put forward as a sound social, scientific, and rural development strategy.

Title of document: Habitat eradication and cropland intensification may reduce parasitoid diversity and natural pest control services in annual crop fields Authors: Deborah K. Letourneau, Sara G. Bothwell Allen, Robert R. Kula, Michael J. Sharkey, John O. Stireman III Journal’s name if any: Elementa Ministry/Government Agency/Organisation: Department of Environmental Studies, University of California, Santa Cruz, California, United States ; Systematic Entomology Laboratory, Beltsville Agricultural Research Center, Agricultural Research Service, U.S. Department of Agriculture, c/o National Museum of Natural History, Smithsonian Institution, Washington, District of Columbia, United States ; Department of Entomology, University of Kentucky, Lexington, Kentucky, United States ; Department of Biological Sciences, Wright State University, Dayton, Ohio, United State Year of publication: 2015 Geographic focus: Global level Main issues / topics addressed (for example: Organic vegetable, parasitoid richnes, Insect sampling, identification, and host range determinations, Habitat elimination around farms and parasitoid diversity……) School of agroecology (if any): Web address to original document (if any): Summary: California’s central coast differs from many agricultural areas in the U.S., which feature large tracts of monoculture production fields and relatively simple landscapes. Known as the nation’s salad bowl, and producing up to 90% of U.S. production of lettuces, broccoli and Brussels sprouts, this region is a mosaic of fresh vegetable fields, coastal meadow, chaparral shrubs, riparian and woodland habitat. We tested for relationships between the percent cover of crops, riparian and other natural landscape vegetation and the species richness of parasitic wasps and flies foraging in crops, such as broccoli, kale and cauliflower, and interpreted our results with respect to the decrease in natural habitat and increase in cropland cover prompted by a local microbial contamination event in 2006. Our key results are that: (1) as cropland cover in the landscape increased, fewer species of parasitoids were captured in the crop field, (2) parasitoid richness overall was positively associated with the amount of riparian and other natural vegetation in the surrounding 500m, (3) different groups of parasitoids were associated with unique types of natural vegetation, and (4) parasitism rates of sentinel cabbage aphid and cabbage looper pests were correlated with landscape vegetation features according to which parasitoids caused the mortality. Although individual species of parasitoids may thrive in landscapes that are predominantly short season crops, the robust associations found in this study across specialist and generalist parasitoids and different taxa (tachinid flies, ichneumon wasps, braconid wasps) shows that recent food safety practices targeting removal of natural vegetation around vegetable fields in an attempt to eliminate wildlife may harm natural enemy communities and reduce ecosystem services. We argue that enhancing biological diversity is a key goal for transforming agroecosystems for future productivity, sustainability and public health. Read More

Title of document: Finding alternatives to swidden agriculture: does agroforestry improve livelihood options and reduce pressure on existing forest? Authors: Syed Ajijur Rahman . Jette Bredahl Jacobsen . John Robert Healey . James M. Roshetko . Terry Sunderland Journal’s name if any: Ministry/Government Agency/Organisation: Forest and Nature for Society (FONASO, initiated by the Erasmus Mundus programme of the European Commission to enhance and promote European higher education throughout the world) and Center for International Forestry Research (CIFOR). Bangor University, University of Copenhagen, and ICRAF Year of publication: 2016 Geographic focus: National Main issues / topics addressed (for example: Agroforestry, adoption Income, Social potential, Forest protection, Policy support ……) School of agroecology (if any): Web address to original document (if any): Summary: Swidden cultivation can contribute to deforestation and land degradation, which can subsequently result in a number of serious environmental problems. This paper examines the economic and social potential of agroforestry systems and the barriers to their widespread adoption, as a land use alternative to swidden cultivation, which may potentially help protect local forest. The Gunung Salak valley in West Java, Indonesia is presented as a case study. Based on farmers’ and experts’ assessment, costs and benefits have been estimated, which show that the two investigated agroforestry systems have higher net present value and benefit-cost ratio (B/C) than the two swidden cultivation systems. Tree ownership also creates more permanent rights to farmland and is prestigious in the community. Agroforestry products (fruit, vegetables etc.) have high monetary value and help strengthen social cohesion when shared with neighbors. However, farmers are reluctant to implement agroforestry. Stated reasons are related to both culture and capacity. Farmers practicing agroforestry are less involved in forest clearing and forest products collection than swidden farmers indicating that it may contribute positively to conservation of local forests. Increasing the adoption of agroforestry farming in the study area will require support to overcome capacity constraints. Read More

Title of document: Alder trees enhance crop productivity and soil microbial biomass in tea plantations Authors: P.E. Mortimer, H. Gui, J. Xu, C. Zhang, E. Barrios, K.D. Hyde, Journal’s name if any: Applied Soil Ecology Ministry/Government Agency/Organisation: Key Laboratory of Plant Biodiversity and Biogeography of East Asia (KLPB), Kunming Institute of Botany, Kunming, China; World Agroforestry Centre, East and Central Asia, Kunming, China; School of Science, Mae Fah Luang University, Chiang Rai, Thailand; Changning Forest Ownership Management Service Center, Baoshang, Yunnan, China; World Agroforestry Centre, Headquarters, Nairobi, Kenya Year of publication: 2015 Geographic focus: Global level Main issues / topics addressed (for example: Agrofoestry, Alnus nepalensis, Crop productivity, Soil bacterial, soil fungi and tea monoculture…) School of agroecology (if any): Web address to original document (if any): Summary: Monoculture farming systems lead to soils depleted of nutrients and diminished microbial functional diversity, disrupting processes crucial to maintaining soil health. The planting of trees in these monoculture systems is one way to improve soil nutrition and biodiversity. Therefore, the objective was how planting the N-fixing tree Alnus nepalensis (7 years old), into monoculture tea (camellia sinensis var, assamica) plantation (32 years old), influences the soil fungal and bacterial communities, and how this impacts on tea productivity. Soil samples (0-15, 15-30, 30-60 cm depths) were collected from plantations of monoculture tea and tea interplanted with A. Nepalensis trees. The samples were analyzed for basic soil properties and nutrients. Phospholipid fatty-acid analyses were conducted on the soil samples to determine the microbial functional groups and biomass of bacterial and fungal communities. Biomass of soil fungi and bacteria were 41% and 10% higher in the tea + A. nepalensis sites than in the tea monoculture sites, respectively. These higher levels were recorded despite there being no changes in the diversity of the soil fungi and bacteria, or the soil nutrition, between the different sites. Tea productivity increased between 52% and 72%, and is attributed to the increases in the soil community biomass. Ectomycorrhizal biomass, as well as Gram-positive, Gram-negative, and actinomycetes bacterial biomass, all increased ranging from 10% to 83%. These groups of organisms have been shown to contain plant growth promoting characteristics, contributing toward increased crop productivity. We provide clear evidence that A. nepalensis in tea plantations promotes the growth and development of the soil microbial communities and that this impacts on above ground productivity. This study highlights the benefits of introducing N-fixing tree species, such as A. nepalensis, into monoculture systems, and how this relates tosoil health and harvest yield. Applied Soil Ecology addresses the role of soil organisms and their interactions in relation to: agricultural productivity, nutrient cycling and other soil processes, the maintenance of soil structure and fertility, the impact of human activities and xenobiotics on soil ecosystems and bio (techno) logical control of soil-inhabiting pests, diseases and weeds.

Title of document: Assessment of Rice IPM Practice and Inputs Authors: Roy Bateman and Le Cao Luong Journal’s name if any: Ministry/Government Agency/Organisation: Farmers and Storekeepers in Dong Thap – A Province in the Mekong Delta Region of Viet Nam. Year of publication: 2015 Geographic focus: National level Main issues / topics addressed (for example: Action thresholds, Natural enemies and biological control agent, IPM strategy, crop protection product, spraying practice and application equipment…) School of agroecology (if any): Web address to original document (if any): Summary: 1. A greatly improved training infrastructure is needed on pesticide science as part of the integrated pest management (IPM) curriculum: for farmers, spray contractors, retailers and agricultural colleges. Key weaknesses include the apparent confusion, by both store-keepers and farmers, about mode of action (MoA) with mode of dose transfer: in which case the prospects for effective IRM are fairly bleak. Products with questionable AI mixtures are a registration issue that should be addressed. Farmer ‘cocktails’ and late-season applications are also a significant problem. A curriculum for responsible selection and use of crop protection products is given, covering important health-related and technical issues such as: MoA, resistance, resurgence, residues (the ‘three Rs’), the importance of pre-harvest intervals and rational application techniques. 2. Pesticide application: existing practices are unsafe and inefficient. Most (>99 %) farmers and contractors walk into their own spray, with virtually all farmers relying on PPE as their ‘first line of defence’. The design of spraying equipment contributes to very inefficient application. Engineering solutions might involve the introduction of tail-booms and specifying equipment capable of using international nozzles, which would both improve safety and save famers money: both for labour (work rate) and more efficient use of PPPs. Volume application rates in post-tillering rice average 400 L/ha, but it is technically feasible to reduce this substantially, with commensurate reduction of inputs: thus potentially making the work attractive to farmers and attainable within a medium-term project. In the longer term, adoption of international (e.g. FAO, ISO) standards and higher-level training and research are needed in this area. We suggest the formation a national (or regional) pesticide application unit, possibly in the form of a University-based lab, be set-up to address these issues. 3. Only a small minority of farmers in Đồng Tháp even claim province practice IPM (84% reported that they do not) and most farmers evidently are spraying unnecessarily. Most farmers spray their fields merely on incidence of pests, or preventatively. An especially common insect thus treated is the rice leaf-roller, Cnaphalocrocis medinalis, with a large number of products specifically registered for this ‘pest’. Similar levels of BPH were reported by farmers (92% in Winter-Spring, 84% in Summer-Autumn crop); rice blast is the principal disease and Echinochloa spp. are the most important weeds. We suggest that it time to seriously re-evaluate the role of action thresholds as part of a realistic IPM strategy for the main rice pests and introduce clear, simple guide-lines for farmers: agreed by major stake-holders and conforming to a code of practice. Maintaining awareness of natural enemies is needed – especially for younger farmers in the post-1990s IPM-FFS generation, who are influenced by intensive advertising on the TV and elsewhere. However, a substantial minority (46%) are aware of natural enemies (NE) in their fields and a few farmers know about a wide range of NE. More than 80% of farmers claimed to use ‘selective pesticides’ (the question refers to all categories). However, biopesticides (if fermentation products are excluded) enjoy on a tiny proportion of the market: slow action and storage issues were frequently alluded-to as constraints, but as above, we discuss the need for realistic guide-lines for use and better training.
