Sorption, uptake and biotransformation of 17β‐estradiol, 17α‐ethinylestradiol, zeranol and trenbolone acetate by hybrid poplar
Hormonally active compounds may move with agricultural runoff from fields with applied manure and biosolids into surface waters where they pose a threat to human and environmental health. Riparian zone plants could remove hormonally active compounds from agricultural runoff. Therefore, sorption to roots, uptake, translocation, and transformation of three estrogens (17β‐estradiol, ...

Effects of the herbicide dicamba on non‐target plants and pollinator visitation
Nearly 80% of all pesticides applied to row crops are herbicides, and these applications pose potentially significant ecotoxicological risks to non‐target plants and associated pollinators. In response to the widespread occurrence of weed species resistant to glyphosate, biotechnology companies have developed crops resistant to the synthetic‐auxin herbicides dicamba or 2,4‐D, and once ...

Agroecology can help fix our broken food system. Here’s how.
The various incarnations of the sustainable food movement need a science with which to approach a system as complex as food and farming. This story was co-published with Food Tank, a nonprofit organization focused on building a global community for safe, healthy, nourished eaters. Thumb through U.S. newspapers any day in early 2015, and you could find stories on President Obama’s ...

The extrapolation of the leaf area-based transpiration of two xerophytic shrubs in a revegetated desert area in the Tengger Desert, China
Plant transpiration plays a key role in sand-binding zones, but obtaining accurate estimates at an integrated leaf-individual-canopy scale is difficult. In this study, transpiration rates of two typical xerophytic shrubs, Caragana korshinskii and Artemisia ordosica, were investigated during the growing season (April–October) from 2008 to 2012 in the Tengger Desert, a revegetated desert ...

Quantitative assessment of the impacts of irrigation on surface water fluxes in the Tarim River, China
Irrigation is a significant human activity that affects surface water fluxes in the Tarim River Basin. To quantitatively assess the irrigation impact of this activity on surface water fluxes in the Tarim River, a land surface hydrologic model was coupled with a modified irrigation scheme and a reservoir module and applied to simulate these fluxes. Modeling results indicate that the combined ...

Sustaining Mali’s Inner Niger Delta
The Inner Niger Delta in central Mali is a giant green oasis on the edge of the Sahara desert. It is one of the country’s most productive areas, but also among its poorest. At the height of the wet season, when the River Niger is swollen by heavy rainfall in Guinea, an area the size of Belgium, from Mopti to Tombouctou, turns into a landscape of lakes. As I discovered on a previous visit ...

What is the Future of Horticultural Science in Africa?
Horticulture is a labour intensive sector that is important for human wellbeing: 'agriculture supplies protein, carbohydrates and staple crops - but we would have a pretty boring life without horticulture.' Nevertheless, in many countries, faculties of agriculture and their departments of horticulture have been swallowed by schools of life or earth sciences. As a result horticulture gets ...

Recreational value of regional forests: the case of Belgium’s Walloon region
The Walloon forest 1 , which is geographically close to densely populated areas of Atlantic Europe, fulfils an important recreational function. Two surveys were set up, among which a large-scale statistical survey in 40 woodlands, distributed throughout the Walloon forest and resulting in over 4,000 questionnaires collected. These give information about the recreational activities carried out ...

Peru: Olmos irrigation project sparks development debate
The recently launched irrigation and hydropower Olmos megaproject in Peru is hailed a ‘masterpiece of engineering’ aimed at stimulating rural development — but some fear the initiative will mostly benefit big companies. The project will bring water from the Atlantic side of the Andes to the Pacific side through a tunnel in the mountains, to irrigate the arid Olmos Valley in the ...

Can medicinal plants alleviate poverty and protect Nepal’s fragile environment?
Farmers in the high Himalayas partner with a U.S.–based nonprofit to cultivate medicinal plants — and the environmental and economic benefits they offer. On a trip to their childhood home in eastern Nepal in the early 2000s, Nepalese staff members of the Mountain Institute — an organization headquartered in Washington, D.C., that works to protect mountain environments and ...

Assessing long-term water quality impacts of reducing phosphorus fertilizer in a US suburban watershed
Phosphorus run-off from urban lawn care is a significant water quality concern in many US suburban communities. Many state and municipal governments in the USA adopt urban fertilizer laws or ordinances that prohibit the use of phosphorus-containing lawn fertilizers. This study assesses the long-term water-quality impacts of two phosphorus-reduction scenarios in a suburban watershed in Central ...

Competing for water: golf courses in semi-arid regions. The case in Spain
The proliferation of golf courses in tourist areas in the Mediterranean has increased water needs substantially. The objective of this paper is to model the political process associated with water distribution decision-making in water-scarce areas. This has been done by developing a pressure group model. Results allow the relative importance of pressure group size and the relationship between ...
