Microalgal oil production for use in rice farms in Albufera (València) region
In the Albufera (València) region of Spain, rice has been farmed for nearly 500 years. Post-harvest flooding of rice fields has become an integral element of wetland refuge for migratory birds. The steady rise in the cost of purchased inputs is causing considerable economic stress to the viability of rice farming in this region. In 2011, it has been estimated the cost of purchased diesel ...

Influence of Capacity Building on Technical Efficiency of vegetables and rice farmers in Bangladesh: JICA intervention in Comilla project
This study examines the influence of Capacity Building (CB) on Technical Efficiency (TE) of farming community in the Comilla project area, Bangladesh, which occurred due to the intervention of Japan International Cooperation Agency (JICA). The results indicated a significant variation in TE of vegetable and rice Production Inside (IP) and outside the project area. The farmers with low-, medium- ...

The costs of adaptation: changes in water availability and farmers’ responses in Punakha district, Bhutan
There is growing evidence that monsoon patterns are changing in the Himalayan region, which could potentially result in loss and damage for local farmers. To understand how farmers adapt to changes in water availability, we conducted a study in Punakha district, Bhutan, using qualitative and quantitative research tools. According to 91% of 273 respondents, water availability for rice irrigation ...

Transferring irrigation management to farmer's associations: Evidence from the Philippines
Irrigation management transfer (IMT) is an important strategy among donors and governments that aims to strengthen farmer control over water and irrigation infrastructure. In this study, we use data from a survey of 68 irrigator associations (IAs) and 1020 farm households in the Philippines to examine the impact of IMT on irrigation association performance and on rice yields. We find that the ...

Field trial carried out in the ebro valley, Spain case study
Rice farmers in Spain experience two major problems with their rice crops: After the flooding and fertilisation of the rice fields algal growth rapidly develops and covers the surface of the water in the paddy. This greatly reduces the availability of sunlight received by the seedlings until they have grown above the water level. This results in early stage plant loss which can be severe. The ...

Have humans tilted the climate books out of balance?
In the great book-keeping of climate change, scientists have just discovered a big mistake. They have been wrong, they now think, to count on the mountains, the plains, the forests and the grasslands as an agency that slows climate change by absorbing carbon dioxide. It does absorb carbon dioxide. But the chilling news is that the soil itself may be making the world warmer. That is because ...

How three U.S. mini-farms are sowing the seeds of global food security
Tiny, biointensive operations show smallholder farmers from around the world how they can grow far more food than conventional approaches. Her face shaded by a wide-brimmed straw hat, Olawumi Benedict is cheerfully tending to her “little babies” — kale seedlings growing in shallow wooden flats until they’re hardy enough for transplantation into soil beds. Three miles over ...

Triangular transplanting pattern and split nitrogen fertilizer application increase rice yield and nitrogen fertilizer recovery
Field experiments were conducted to evaluate the effects of improved crop management (OPT) for irrigated rice (Oryza sativa L.) on grain yield and N recovery efficiency in southwestern China. In the OPT treatment, rice seedlings were transplanted in a triangular spatial pattern and the N fertilizer was split, based on the difference between the estimated total N requirement and the soil and ...

Can grains of the past help us weather storms of the future?
Combining science with traditional knowledge, researchers turn to ancient rice as a source of climate resilience In May 2009, Cyclone Aila wreaked havoc in eastern India. Clocking in at speeds of over 120 kilometers per hour, Aila hit the Sundarbans, the largest continuous block of mangrove forest in the world, located in the Ganga-Brahmaputra tidal delta on the Bay of Bengal. The storm killed ...

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 ...

Making sustainable intensification work on sound evidence
Assessing the real-world impact of new agronomic practices depends on good economic studies, says David Spielman. A new narrative is slowly taking hold of today's collective thinking about productivity, growth and poverty reduction in developing-country agriculture: the concept of sustainable intensification. Sustainable intensification hinges primarily on practices and technologies that help ...

Plan B 3.0 -- A Plan of Hope
Plan B is shaped by what is needed to save civilization, not by what may currently be considered politically feasible. Plan B does not fit within a particular discipline, sector, or set of assumptions. Implementing Plan B means undertaking several actions simultaneously, including eradicating poverty, stabilizing population, and restoring the earth’s natural systems. It also involves cutting ...
