More rain = less trees

Article2Research from Princeton University published recently has found a relationship between higher rainfall and lower numbers of trees in savannah ecosystems in Southern Africa. The researchers have used mathematical models, in conjunction with ground truthing to validate an explanation for this. Their argument is, that grasses are more effective and efficient at making use of higher rainfalls, and therefore prosper at times of increased rain. Trees however are not as efficient at using abundant water resources, but are more effective at surviving in longer, dryer times. As such, savannahs that have been affected by higher rainfall, have comparably less trees than those in dryer areas.

Is this evidence that nature is promoting trees as an adaptation to less rain? Current predictions of climatic variation include both increased extreme weather events, and periods of both drought and high rainfall. This information may assist in predicting how savannah ecosystems are likely to react to long term variation and can be used to assist in planning and prioritizing management practices such as farmer managed natural regeneration and sustainable grazing regimes, given the likely pressures that either trees or grasses may be under in the future.

While the research indicates warns of threats to trees in savannah ecosystems in periods of intense rainfall, on the other hand, it also promotes the value and role of trees in dry periods. Times of high rainfall, while not without their challenges of flooding etc, are generally times of abundance, good crop production, high grass growth and fat animals. Dry periods however are associated with crop failure, livestock losses, and food insecurity. The greater resilience of trees during these periods, highlights their value for maintaining biomass (that can be used for fodder or other non-timber tree products), and increasing the resilience of ecosystems and the communities that rely on them in dry periods. Evergreen Agriculture systems that encourage a healthy mix of tree, pasture and crop production systems also recognize this value, and will be of increased significance in the future.

Barking up the right tree

20462071041_539e1bd180_cThe Africa Rising Project of the World Agroforestry Centre has successfully changed the beliefs and misconceptions of farmers in Tanzania’s Kongwa and Kiteto Districts. The belief that trees could suck away nutrients from food crops has now been erased with farmers now enjoying the benefits of intercropping multipurpose trees with their crops. Additionally, the project is establishing various landscape based agroforestry practices to improve access to fodder, fuel wood and control soil erosion in Tanzania.

Trees grow ‘like children’

Dreaming of an Evergreen future for the DRC

DSC02133At the start of this year, Patrick Kaka dreamt of trees for his community in eastern Democratic Republic of Congo (DRC), and lots of them!

Despite some initial challenges with missed funding opportunities and a quick trip across the border to Burundi to get tree seedlings, Patrick was able to realize his dream in early October. This was through the inauguration of a National Tree Day (Arbor Day equivalent) for his home community on the shores of Lake Kivu, eastern boarder of the DRC. Through his NGO, GIERI (Groupe d’Intervention Pour l’Encadrement Et La Rehabilitation Integral or Intervention Group for Farming and Integral Rehabilitation), Patrick was able to access some support from GIZ and work his community through a Landcare approach, to embark on the start of his EverGreen Agriculture dream for eastern DRC.

DSC02097In what is considered a first for the region, the tree-planting day on the 8th October 2015 attracted the participation of the Provincial Minister of Agriculture, the military and local residents, to plant over 5,000 agroforestry species, including Faidherbia, Gliricidia and Eucalyptus, within farmer fields near Bukavu.

Patrick commented that the focus of the day was to raise awareness amongst the community of the importance of trees for both environmental protection and household livelihoods. He added that the participating community were grateful for the integration of trees and shrubs directly into their agricultural fields which will increase the productivity, income and resilience of their farming systems.

The planning and implementation of the tree planting program was heavily reliant on the community adopting a Landcare approach to their activities, through instilling ownership and management of the natural resource amongst the community. Patrick noted that creating public awareness of the tree planting activities through a participatory framework was a key driver, in addition to engaging other relevant partners, such as the local authorities to support environmental management initiatives on private lands.

DSC02129When asked what the future challenges for communities in eastern DRC were, Patrick noted that “farmers in our community need guidance in technical skills for nursery management and species diversity for high-yielding species inter-cropped in farming land. We also need enabling policies and incentives to invest in environmental services that protect biodiversity, sustainable land and water management around Lake Kivu”.

Where Africa youth fit into the future of agriculture?

imageIncreasing the participation of youth in agriculture is a global challenge. Yet it remains particularly perplexing within an African context, given the growing demand for food supply and emerging diversity in diet nutrition.

Marion Moon, founder and managing director of Wanda Organic Limited, considers the lack of appeal of employment in agriculture as failure to consider the market and how to meet (and create) market demands along the supply chain.

The unexploited solution according to Ms. Moon, however, lies within our reach. That is, packaging and commercializing agricultural innovations in stimulating and incentivized ways. As a result, there are a number of opportunities to have youth pursuing agriculture as a viable venture for economic development and innovators in this field should:

• Introduce competitive activities whereby users will receive prices at the end
• Provide technical assistance on the innovation making it sensible to the market
• Provide technical assistance on the business e.g. IT needs
• Brand products in simple and enticing ways
• Explain the cash flow
• Practice contract farming through ready markets and supply chains
• Make the innovation very efficient through technology such as mobile applications
• Pitch the innovation based on what people want at the moment
• Establish partnerships along the chain
• Simply state the diverse benefits and immediate returns
aAccording to Ms. Moon, this way government, national and international NGOs and various projects will develop business plans that will ensure uptake of their innovations based on great marketing techniques. In the same manner, the youth will be well advised on the most viable tree species based on their desire to have quick cash flow at their convenience.

Project initiated to build resilient farming systems

116931F02BFD13B1EB9F3CFF0B34E477A large-scale project that seeks to help smallholders adapt to climate change by practicing agricultural systems that integrate tree planting, rearing of livestock and crop production has begun in West Africa. the Building Resilient Agro-forestry Pastoral Systems through Participatory Action Research (BRAS-PAR) project aims to improve the understanding of farmers’ perceptions and demands by addressing barriers to technology adoption while taking into consideration gender and social differentiation.
