Production of staple crops, such as maize, is under increasing risk in Africa because of climate change and depleting soil fertility. The potential consequences for food security are dire. Climate change and food security must be tackled together.
Modern methods of agroforestry and “conservation agriculture with trees” are employing age-old indigenous practices of natural fertilisation with dramatic effects. Field studies show that growing maize under “fertiliser trees” can more than triple the yields.
“Evergreen agriculture” practices (where trees are intercropped in annual food crop and livestock systems) help retain water in soils during droughts and prevent landslides and erosion during heavy rain, so reduce vulnerability to climate extremes.
The capacity for these practices to also retain and store carbon in soils means that the potential climate change mitigation benefits of wide-scale evergreen agriculture in Africa are large and globally significant – potentially up to 50 billion tonnes of carbon dioxide over 50 years.
The challenge of spreading the knowledge and uptake of evergreen agriculture and other “climate-smart” agriculture practices is being taken on as a priority by regional governance bodies in Africa.
Payments for ecosystem and social impact services may be one means to fund the practical on-farm research, testing and knowledge transfer needed for adoption on a wide scale. Carbon funds, from biocarbon projects, are one possible source of finance, but uptake is still at very low levels.
The costs of measurement, reporting and verification can be prohibitive and new methods are needed.
Supported NAMAs (nationally appropriate mitigation actions) programs of evergreen agriculture could be a new approach and play a key role in Africa low carbon development strategies.
As we all known that producing need to fermente the raw material,and in order to meet the needs of the produce,the fertilizer machine manufacturers are designing the new fermentation compost turning machine.Our company have been design all kinds of fermentation compost turner machine.Different type have different capacity per hour.And these fertilizer machines have different featureToday this article will introduce the fertilizer machine for you.

In February, Arable sat down with seventh-generation North Carolina farmer Charles Dietzel to discuss the newest incarnation of his legacy farm, Carolina Heritage Farms. We talked about his family’s transition from tobacco to agroforestry to now growing industrial hemp, and the role agtech has played in their decision to make the switch. With all the possibilities that come along with industrial hemp, visibility and traceability are going to be important to the success of the nascent industry. Their first...
Scientists in South East Asia have been measuring greenhouse gas (GHG) emissions from goats and cattle in a series of research projects investigating the effects of different feeding regimes. In each case, the eructed, or belched, emissions from each animal were measured with a portable FTIR gas analyzer from Gasmet Technologies. The research papers have been published by ‘Livestock Research for Rural Development,’ a peer-reviewed international journal for research into sustainable developing world...
CEMA & COPA-COGECA present the European Code of Conduct on data-sharing by contractual arrangement
On 4&5 March the Prague Congress Centre was animated by the participants to the Horizon 2020 SmartAgriHubs project. The event deployed over the course of two full days, followed by an extra “Synergy Day” with the other big Horizon 2020 project in the field of agri-food, IoF2020.
SmartAgriHubs is a project dedicated to accelerating the digital transformation of the European agri-food sector....
Problems with medical waste.
Medical waste disposal represents one of the single most serious challenges for developing countries. Most of which is dumped on open land, presenting challenges for today’s generation and future generation to come.
Through the piles of illegally dumped, medical waste, scavengers run the risk of infection while searching for used syringes to sell as profit. The re-use of these syringes further spreads diseases such as HIV, hepatitis B & C, with around 2 million infections....
