Yam anthracnose is one of the most serious fungal diseases affecting white and water yam production. Screening of available landraces for new sources of durable resistance to the pathogen is a continuous process. In the present study, the pathogens causing anthracnose in Dioscorea alata and Dioscorea rotundata farms in Cross River State yam belt region were characterized. Diseased yam leaves with anthracnose symptoms collected from the farms were used in the isolation, purification and, identification of C. alatae strains using morphological, cultural, and molecular methods.

Earthworms (EWs) could be a viable indicator of soil biology and agri-food system management. The influence of climate-smart agriculture (CSA)-based sustainable intensification practices (zero tillage, crop rotations, crop residue retention, and precision water and nutrients application) on earthworms’ (EWs) populations and soil physico-biochemical properties of rice-wheat cropping system in the Indo-Gangetic plains of South Asia was investigated.

Genome–environment Associations (GEA) or Environmental Genome-Wide Association scans (EnvGWAS) have been poorly applied for studying the genomics of adaptive traits in bread wheat landraces (Triticum aestivum L.). We analyzed 990 landraces and seven climatic variables (mean temperature, maximum temperature, precipitation, precipitation seasonality, heat index of mean temperature, heat index of maximum temperature, and drought index) in GEA using the FarmCPU approach with GAPIT. Historical temperature and precipitation values were obtained as monthly averages from 1970 to 2000.

Aquaculture plays an increasingly important role in meeting the rising global demand for fish fuelled by economic and demographic growth. However, in many middle-income countries, aquaculture is constrained by rising labour costs, limited input supply, environmental concerns, and infectious diseases. In this paper, we developed a multi-species, multi-sector equilibrium model and applied it to the fishery sector of Egypt, a leading aquaculture producer in Africa, to examine these barriers.

Synchronizing nitrogen (N) fertilization with planting date (PD) could enhance resource use efficiency and profitability of upland rice (Oryza sativa L.) production in Thailand. The objective of the study was to assess upland rice responses to four N fertilization rates (NFRs) and three planting dates. Field experiments were conducted during two growing seasons under four NFRs, no N applied (N0), 30 (N30), 60 (N60), and 90 kg N ha−1 (N90), and NFR were applied at the initiation of tillering and panicle emergence stages.

High temperature and water deficit are among the major limitations reducing lentil (Lens culinaris Medik.) yield in many growing regions. In addition, increasing atmospheric vapor pressure deficit (VPD) due to global warming causes a severe challenge by influencing the water balance of the plants, thus also affecting growth and yield.

The objective of this study is to map community solutions to deal with climate variability and how information is mobilized into or interfaces with the next layer of government interventions that brings new perspectives in understanding how local solutions can be better mobilized into external solutions to climate change adaptation through horizontal and vertical integration processes, with a focus on living community-based water tenure in rural Zambia.

Within Nepal, water, energy, food, and ecosystems (WEFE) are vital resources not merely for the current generation, but also for future ones, especially to satisfy the demands of a growing population and to respond to socio-economic changes. The WEFE nexus approach realizes that the management of water, energy, food, and ecosystems must be undertaken in a holistic way. Nevertheless, governments, investors, and other stakeholders face challenges in the management of WEFE resources, particularly in the face of climate change.

Kalu Ganga, a major tributary of Amban Ganga, is one of the perennial rivers of Sri Lanka. Also, Amban Ganga is a major tributary of Mahaweli Ganga. The Kalu Ganga starts from Knuckles mountains, and about 90% of the catchment is covered with forests. The Government of Sri Lanka constructed Kalu Ganga and Moragahakanda Reservoirs in 2014 to increase the water availability in Mahaweli Basin to improve the agricultural and drinking water benefits in several provinces.

WP 4: Integrated food, land, water, and energy systems for climate-resilient landscapes
Inception Workshop Morocco May 17, 2022.

2021 was WLE’s final year – the culmination of a decade of science and impact. Throughout the year we saw the real-world difference made by our flagship projects and watched solutions unfold at landscape and basin scales. We also saw our research flow into larger processes in a year of international action that included the UN Food Systems Summit and high-stakes meetings of the UN Conventions on Climate Change and Biological Diversity.
