Seedlings of Artemisia herba-alba grown in glasshouse were watered with differing salinities (0, 150, 250 or 350 mM NaCl) and watering frequencies of 3, 7, 14 or 21 days for a period of 6 weeks. At the end of the study, plant survival, dry matter yield, biomass allocation (shoot and root), leaf area, relative growth rate (RGR), net assimilation rate (NAR), specific leaf area (SLA) and leaf area ratio (LAR) were recorded. When watered with 0 mM NaCl, Artemisia herba-alba plants had similar (P> 0.9) final dry matter weight and 100% survival regardless of watering frequency.

This study was conducted in Werii watershed (1797 km2) of Tekeze river basin, through integrative use of hydrological and climate models with the objective of estimating the impact of climate change on groundwater recharge and groundwater potentials. Statistical downscaling model (SDSM) was used to downscale precipitation and temperature outputs from REMO (REgional climate MOdel) which in turn was used as input to the WetSpa model to simulate future water balance changes based on A1B and B1 SRES emission scenarios.

This technical paper details findings and outcomes from the workshop hosted by the Climate Change Unit of Ministry of Agriculture, Livestock and Fisheries of Kenya, along with the FAO, ICRAF and CCAFS. The process engaged stakeholders from research, practice and policy and to interactively share and analyze scientific evidence and field experience from over 40 projects related to climate-smart agriculture (CSA) within integrated farming systems in Kenya.

Mechanisms for Sharing Benefits, or MCB, seek to redistribute equitably, among all users, the benefits of water gives us a basin preserved. The MCB are aimed at creating a virtuous circle between the welfare of the people and ecosystems in which they live.

In response to changing urban food systems, short supply chains have been advocated to meet urban food needs while building more sustainable urban food systems. Despite an increasing interest in urban food supply and the flows of food from production to consumption, there is a lack of empirical studies and methodologies which systematically analyse the actual proportion and nutritional significance of local and regional food supplied to urban markets.

Global food demand is increasing rapidly, as are the environmental impacts of agricultural expansion. Here, we project global demand for crop production in 2050 and evaluate the environmental impacts of alternative ways that this demand might be met. We find that per capita demand for crops, when measured as caloric or protein content of all crops combined, has been a similarly increasing function of per capita real income since 1960. This relationship forecasts a 100–110% increase in global crop demand from 2005 to 2050.

The resolution adopted by the General Assembly of the United Nations on 25 September 2015 is symptomatic of the water-energy-food (WEF) nexus. It postulates goals and related targets for 2030 that include (1) End hunger, achieve food security and improved nutrition, and promote sustainable agriculture (SDG2); (2) Ensure availability and sustainable management of water and sanitation for all (SDG6); and (3) Ensure access to affordable, reliable, sustainable, and modern energy for all (SDG7).
