“…The uncultivated coastal saline plains of the Western Bohai Rim in Northern China are about 670,000 ha, accounting for nearly a quarter of the area with low agricultural production in this region [3,4]. The soils of these plains are highly saline with low crop productivity and cannot meet local agricultural demands for food [4].…”

Flat (F), mini-ditch (MD), and ridge-furrow (RF) are three conventional cotton planting patterns that are usually adopted around the world, yet soil and crop responses to these three patterns are poorly studied, as is their suitability for increasing yield for coastal areas in Eastern China. The effects of three planting methods on water and salt dynamics as well as on growth and lint yield of cotton (Gossypium hirsutum L.) were investigated in a saline field in Bohai Rim, China, to select the best planting pattern for cultivating coastal saline fields of Eastern China. Soil moisture in the root zone with RF was 11.9% and 12.1% higher than with F and MD, whereas the electrical conductivity of a saturated soil extract (EC e ) in the root zone with RF was 18.0% and 13.8% lower than with MD and F, respectively, during the growth period, which indicated that RF could efficiently collect rainfall and leach salt in the root zone. After drip irrigation, the infiltration and salt-leaching depth with RF were both deeper than that with F and MD. The stand establishment of MD was the highest (80.3%) due to the greenhouse effect from film mulching, and was 12.8% and 4.6% higher than that with F and RF, respectively. Growth indicators and lint yield demonstrated that RF was superior to F and MD because of the higher soil moisture and lower EC e . The lint yield was significantly higher in RF, suggesting that RF can be an optimal planting pattern for agricultural reclamation in similar saline-alkaline areas around the world.

“…High level of EC strictly related to water salinity is one of the main problem especially in the arid and semi-arid Mediterranean areas where abiotic stresses negatively impact crops growth and yield, degrade the land, and pollute groundwater [40][41][42][43]. The salt-affected areas amount to some 16 million ha or 25% of the total irrigated land, although detailed information about each country remains scarce, and a deteriorate of situation may be observed in the future due to the effects of climate change on the precipitation, evaporation, runoff, and soil moisture storage [9].…”

Abstract:In the Mediterranean arid and semi-arid regions, large amounts of low quality waters could be used for crop irrigation, but the adoption of articulated classifications with too rigid quality limits can often reduce the recoverable quantities of water and make the monitoring of water quality too much expensive. Therefore, an evaluation of irrigation water quality based on only a few crucial parameters, which consider the crop species to be irrigated and the type of irrigation system and management adopted, can be an easy and flexible method for maximizing the reuse of wastewater and low-quality water for agricultural purposes. In this view, an irrigation water quality tool (IWQT) was developed to support farmers of arid and semi-arid regions on evaluating the use of low quality water for crop irrigation. The most significant and cheapest parameters of irrigation water quality were identified and clustered in three quality classes according to their effects on crop yield and soil fertility (agronomic quality indicators), human health (hygiene and health quality indicators), and irrigation systems (management quality indicators). According to IWQT parameters, a tool reporting a series of recommendations, including water treatment types, was implemented to guide farmers on the use of low quality irrigation water.

“…For example, during salt-induced degradation, salt-affected lands lose a significant fraction of their original carbon pool (Ivits et al, 2013) and biomass productivity potential (John et al, 2005). The magnitude of the loss may range between 10 and 30 t carbon/ha depending on the original size of the carbon pool and the severity of land degradation (Lal, 2001).…”

Resource Recovery and Reuse (RRR) is a sub-program of the CGIAR ResearchProgram on Water, Land and Ecosystems (WLE) dedicated to applied research on the safe recovery of water, nutrients and energy from domestic and agro-industrial waste streams. This SRP aims to create impact through different lines of action research, including (i) developing and testing scalable RRR business models, (ii) assessing and mitigating risks from RRR for public health and the environment, (iii) supporting public and private entities with innovative approaches for the safe reuse of wastewater and organic waste, and (iv) improving rural-urban linkages and resource allocations while minimizing the negative urban footprint on the peri-urban environment. This sub-program works closely with the World Health Organization (WHO), Food and Agriculture Organization of the United Nations (FAO), United Nations Environment Programme (UNEP), United Nations University (UNU), and many national and international partners across the globe. The RRR series of documents present summaries and reviews of the sub-program's research and resulting application guidelines, targeting development experts and others in the research for development continuum. He is a water and soil management scientist with a focus on developing countries, and interests in water recycling and the safe and productive use of wastewater, water quality and environmental health, and amelioration of salt-induced land degradation. He has implemented multi-disciplinary projects and directed research teams in Central and West Asia, and North Africa. Manzoor has more than 100 peerreviewed publications to his credit. He serves on the editorial boards of four international journals. Science with a human face
