  • Critical source area management of agricultural phosphorus: experiences, challenges and opportunities

    The concept of critical source areas of phosphorus (P) loss produced by coinciding source and transport factors has been studied since the mid 1990s. It is widely recognized that identification of such areas has led to targeting of management strategies and conservation practices that more effectively mitigate P transfers from agricultural landscapes to surface waters. Such was the purpose of P ...

  • Water for agriculture and the environment: the ultimate trade-off

    Global population is projected to increase over year 2000 levels by 30% in 2025 and by 50% in 2050. Producing sufficient food to feed a more populous Earth will be a challenge requiring additional developed water supplies. Existing supplies are unevenly distributed around the planet. Some developing countries lack sufficient water to grow the food necessary to feed the growing population. With ...

  • Watering Scarcity: Private investment opportunities in agricultural water use efficiency

    This report was prepared by Rabobank in collaboration with the World Resources Institute. In many regions around the world, demand for fresh water now outstrips renewable supplies. Water scarcity is projected to worsen considerably due to a combination of factors such as population increase, higher incomes and changing lifestyles, pollution, and climate change. Agriculture is by far the biggest ...

  • Changing mechanisms of agricultural water use in the urbanization and industrialization of China

  • One-Quarter of World’s Agriculture Grows in Highly Water-Stressed Areas

    All living creatures need two things to survive: food and water. A new WRI analysis shows just how much tension exists between those two essential resources. A new interactive map from WRI’s Aqueduct project reveals that more than 25 percent of the ...

  • Meeting the challenges of global rice production

    Rice is the second most widely grown cereal crop and the staple food for more than half the world’s population. More than 3 billion people consume more than 100 kg of rice per year. Rice is cultivated on 155.5 million ha with an average growth rate of 0.39% a year, in the last 30 years. In the near future, the possibility for expanding areas under rice based systems will remain very limited ...

  • Agriculture Plant Nursery - Case Study

    Challenge A plant nursery company had water quality issues from the well water source that there were using for irrigation purposes in their plant growing operations. These water quality issues including total dissolved salts (TDS) around 2500 mg/l, as well as turbidity, mineral hardness and microbiological contaminants. The plants were slow growing. ...

  • Irrigation challenges in the sub-humid US Mid-South

    Irrigated area in the Mid-South USA continues to increase and now totals four million ha. Because of low available water holding capacities and shallow root-limiting layers in many soils, irrigation management is difficult. Water quality and water use efficiency impacts under irrigation are poorly understood, but comprehension is necessary if conversion from groundwater to surface water supplies ...

  • Modelling Common Agricultural Policy–Water Framework Directive interactions and cost-effectiveness of measures to reduce nitrogen pollution

    Selecting cost-effective measures to regulate agricultural water pollution to conform to the Water Framework Directive presents multiple challenges. A bio-economic modelling approach is presented that has been used to explore the water quality and economic effects of the 2003 Common Agricultural Policy Reform and to assess the cost-effectiveness of input quotas and emission standards against ...

  • The Global Food Challenge Explained in 18 Graphics

    The world is projected to hold a whopping 9.6 billion people by 2050. Figuring out how to feed all these people—while also advancing rural development, reducing greenhouse gas emissions, and protecting valuable ecosystems—is one of the greatest challenges of our era. So what’s causing the global food challenge, and how can the world solve it? We begin to answer these questions ...

  • Challenges and opportunities for a sustainable rice production in Europe and Mediterranean area

    Rice is the second largest cereal crop grown worldwide. One-half of the world population and virtually all of East and Southeast Asia is wholly dependent upon rice. Rice production in the Mediterranean regions dates back to the seventh century. This crop was first introduced into Egypt and gradually spread, towards the fifteenth century, to most countries of the Mediterranean basin. Rice is at ...

  • Irrigated agriculture and groundwater resources – towards an integrated vision and sustainable relationship

    Globally, irrigated agriculture is the largest abstractor, and predominant consumer, of groundwater resources, with large groundwater-dependent agro-economies now having widely evolved especially in Asia. Such use is also causing resource depletion and degradation in more arid and drought-prone regions. In addition crop cultivation practices on irrigated land exert a major influence on ...

  • CRISPR is coming to agriculture — with big implications for food, farmers, consumers and nature

    Gene editing offers dramatic advances in speed, scope and scale of genetic improvement. It also offers an opportunity for more nuanced GMO governance. Very few technologies truly merit the epithet “game changer” — but a new genetic engineering tool known as CRISPR-Cas9 is one of them. Since we first developed the ability to alter the genetic material inside a plant or animal in ...

  • How a new way of thinking about soil sparked a national movement in agriculture

    For three weeks every month, Ray Archuleta captivates audiences with a few handfuls of soil. He begins with two clumps, dropping them into water. The soil from a farm where the soil isn’t tilled holds together, while the tilled soil immediately disperses, indicating poor soil structure. Next, volunteers from the audience — mostly farmers and ranchers — pour water over a soil ...
