Global rice production systems face two opposing challenges: the need to increase production to accommodate the world's growing population while simultaneously reducing greenhouse gas (GHG) emissions. Adaptations to drainage regimes are one of the most promising options for methane mitigation in rice production. Whereas several studies have focused on mid-season drainage (MD) to mitigate GHG emissions, early-season drainage (ED) varying in timing and duration has not been extensively studied.

A study has warned that the dry-season irrigated rice in West Africa’s Sahel region has reached the critical threshold of 37 degrees Celcius – the tipping point.

Nagpur: Amid paddy growers of east Vidarbha reeling under a major pest attack, some of them who have adopted organic farming claim they could prevent losses in their fields using natural pesticides

Chinese researchers have found a major quantitative trait locus (QTL) that can be used to cultivate high-manganese, low-cadmium rice, the Chinese Academy of Agricultural Sciences (CAAS) said in a s

The El Niño-Southern Oscillation (ENSO) in 2016 adversely affected Vietnam particularly the Mekong River Delta (MRD), where more than 90% of the country’s rice export is produced annually.

It is a major challenge to achieve the goal of increasing grain yield, nitrogen use efficiency (NUE) and irrigation water productivity (IWP) in cereals. This study investigated if progressive integrative crop management technology in rice (Oryza sativa L.) could improve agronomic and physiological performances, and consequently, increase grain yield, NUE and IWP.

This study is the first of its kind to quantify possible effects of climate change on rice production in Africa. We simulated impacts on rice in irrigated systems (dry season and wet season) and rainfed systems (upland and lowland). We simulated the use of rice varieties with a higher temperature sum as adaptation option. We simulated rice yields for 4 RCP climate change scenarios and identified causes of yield declines. Without adaptation, shortening of the growing period due to higher temperatures had a negative impact on yields (

Without a renewed commitment to policy change, commodity-dependent developing countries (CDDCs) are by 2030 set to lag behind countries with more diverse economies in their social and economic achievements, UNCTAD and the Food and Agriculture Organization of the United Nations (FAO) said in a report.

This publication shares the challenges, lessons learned, and cases of success by partner countries in the Consortium for Unfavorable Rice Environments (CURE).

A critical question for agricultural production and food security is how water demand for staple crops will respond to climate and carbon dioxide (CO2) changes, especially in light of the expected increases in extreme heat exposure. To quantify the trade-offs between the effects of climate and CO2 on water demand, we use a ‘sink-strength’ model of demand which relies on the vapour-pressure deficit (VPD), incident radiation and the efficiencies of canopy-radiation use and canopy transpiration; the latter two are both dependent on CO2.
