Synthetic nitrogen (N) fertilizer has played a key role in enhancing food production and keeping half of the world’s population adequately fed. However, decades N overuse many parts world have contributed to soil, water, air pollution; reducing excessive losses emissions is central environmental challenge 21st century. China’s participation essential global efforts N-related greenhouse gas (GHG) because China largest producer consumer N. To evaluate impact use fertilizer, we quantify carbon...
Understanding yield potentials and exploitable gaps in current intensive maize (Zea mays L.) production is essential order to increase grain yields meet future food requirements amid strong competition for limited resources. In this study, we used simulations with the Hybrid-Maize Model (http://www.hybridmaize.unl.edu/), highest recorded published literature, field experiments, farm survey data assess four agro-ecological regions of China. 50 high-yield sites across China from 1990 2009,...
To achieve food and environmental security, closing the gap between actual attainable N-use efficiency should be as important yield gaps. Using a meta-analysis of 205 published studies from 317 study sites, including 1332 observations rice, wheat, maize system in China, reactive N (Nr) losses, total N2O emissions fertilization both increased exponentially with increasing application rate. On basis loss response curves literature meta-analysis, direct emission, NH3 volatilization, leaching,...
Although the goal of doubling food demand while simultaneously reducing agricultural environmental damage has become widely accepted, dominant paradigm still considers high yields and reduced greenhouse gas (GHG) intensity to be in conflict with one another. Here, we achieved an increase maize yield 70% on-farm experiments by closing gap evaluated trade-off between grain yield, nitrogen (N) fertilizer use, GHG emissions. Based on two groups N application six locations for 16 site-years,...
Traditional weather and climate forecasting is used by many indigenous communities worldwide as a guide in making important decisions that enable them cope adapt to change-induced extreme variation. In pastoral Africa, traditional remains the most accessible affordable source of information. this study, we individual interviews focused group discussions systematically document knowledge among Afar pastoralists, with aim such information available, enhance use change adaptation explore...
Abstract Ensuring food security is the foundation of economic development and social stability. C hina historically a country that dominated by agriculture. In past 60 years, hina's total grain output increased fivefold, from 113 million tons (MT) in 1949 to 571 MT 2011, statistic which provides inspiration producers other parts world. Grain production per capita doubled, 209 425 kg during same time period. At national scale, has succeeded maintaining basic self‐sufficiency for three...
The overuse of Nitrogen (N) fertilizers on smallholder farms in rapidly developing countries has increased greenhouse gas (GHG) emissions and accelerated global N consumption over the past 20 years. In this study, a regional management approach was developed based cost agricultural response to application rates from 1,726 on-farm experiments optimize across 12 agroecological subregions intensive Chinese maize belt. grain yield GHG emission intensity investigated compared field-specific...
Invasive plant species and climate change are among the biggest threats to ecological integrity of many ecosystems, including those protected areas. Effective management invasive plants requires information regarding their spatial distributions. Using maximum entropy, we modeled habitat suitability for an Chromolaena odorata under current future climatic conditions (HadGEM2‐ES MIROC5) in areas four West African countries (Benin, Côte d'Ivoire, Ghana, Togo). Under conditions, approximately...
A lack of basic information on optimal nitrogen (N) management often results in over- or under-application N fertilizer small-scale intensive rice farming. Here, we present a new database input from survey 6611 farmers and yield response to added 1177 experimental on-farm tests across eight agroecological subregions China. This enables us evaluate by develop an approach regional management. We also investigated grain yield, application rate, estimated greenhouse gas (GHG) emissions...
Quantifying potential yield (PY) and gap (YG) is essential for prioritizing research formulating food security policies. Here we used the highest recorded published in literature based on 213 sites ( n = 548) across China to estimate PY, best farmers’ (the mean of 94th 99th decile) according 4552 farm surveys attainable (AY) five wheat Triticum aestivum L.) agro‐ecological regions China. These data were compared with average (FY) assess YG. The PY averaged 9.0 Mg ha −1 while AY was 8.0 . FY...
Controlled release phosphorus (P) fertilizers and humic acid (HA) applications are two effective significant techniques or measures for preventing P loss enhancing maize development. However, the underlying physiological mechanism of how controlled combined with HA affect production P-use efficiency (PUE) remains unknown. The effects applying coated diammonium phosphate (CDAP) together on soil nutrient supply intensity, phosphatase activity, photosynthesis, endogenous hormone contents, yield...
Abstract The great achievement of the development intensive in agriculture China can be partly attributed to substantial increases mineral‐nutrient application. However, whereas farmers tend apply high levels nitrogen (N) and phosphorus (P) application potassium (K) has been neglected. A greater understanding relationship between maize ( Zea mays L.) grain yield K‐application rate is thus required provide an improved rationale for K fertilization various agro‐ecological regions China. In...

Food security is a problem that requires strategic, scientific and comprehensive solutions, has great significance for national the wellbeing of people. As China’s socio-economic development modernization enter new historic phase, its food faced with challenges risks. Managing these risks will be vital importance country people in order to ensure appropriate production, supply consumption. This study begins various aspects provision consumption, analyzes major changes nutrition demand under...
