Food Tank has compiled a list of indigenous fruits, vegetables, and grains from many regions that are nutritious, delicious, and contribute to sustainable livelihoods in rural communities across the globe.

Every day, plant species across the globe are disappearing. The U.N. Food and Agriculture Organization (FAO) reports that approximately 75 percent of the Earth’s plant genetic resources are now extinct, and another third of plant biodiversity is expected to disappear by 2050. Up to 100,000 plant varieties are currently endangered worldwide.

Unfortunately, most investments in agriculture are for crops such as wheat, rice, and maize, rather than for more nutritious foods or indigenous crops—and this focus has had devastating consequences. Global obesity rates have doubled over the last 30 years, increasing the risk of diet-related illnesses including diabetes, hypertension, and heart disease in industrialized and developing countries alike.

Many indigenous crops are environmentally sustainable, improve food security, help prevent malnutrition, and increase farmer incomes. Initiatives like the World Vegetable Center (AVRDC)’s Vegetable Genetic Resources System and Slow Food International’s Ark of Taste are working to catalog indigenous species of fruits and vegetables all over the world.

Current agricultural practices in Mozambique and Lesotho lead to localized externalities and systematic “macro” erosion. However, conservation agriculture, which promotes minimal tillage, intercropping, and maintaining a soil cover, can be applied to moderate erosion and improve food security while sequestering carbon. This presentation examines the greenhouse gas reduction potential Sustainable Agriculture and Natural Resource Management (SANREM) Collaborative Research Support Program’s 5 year project to promote conservation agriculture in Mozambique and Lesotho. It provides graphical comparisons of carbon emissions for tillage and no-tillage systems. Results of a household survey in Mozambique are utilized to examine the probability of the adoption of conservation agriculture related to input use, training, labor constraints, and project support. Farmers who use fertilizer and herbicide and receive credit were found to have the highest adoption rate for conservation agriculture.

Indigenous food crops refer to food crops that have their origin in South Africa. Added to these crops are those that were introduced into the country and are now recognised as naturalised or traditional crops. They are divided into three main categories; namely grains, vegetables and fruit.

South Africa possesses a huge diversity of indigenous food crops, which includes grains, leafy vegetables and wild fruit types. These crops are produced and found growing in the country under various weather conditions. Their production within the rural farming communities is on small scale and is mainly for subsistence purposes. Most of the arable land is used mainly for production of maize and other exotic crops.

This user manual is designed for use by Parties and national experts responsible for the preparation of the various sections of national communications, and also by national climate change teams or committees that facilitate the coordination, organization and management of various tasks and activities. It might also be useful for multilateral and bilateral programmes that support the preparation of national communications from non-Annex I Parties.

Colocasia esculenta L. Schott belongs to the family Aracea and is grown for its edible corms as a staple food throughout subtropical and tropical regions of the world. Amadumbe (the Zulu name for Colocasia esculenta) is consumed by and holds an important place in the diet of local rural people in Kwazulu-Natal, South Africa. Three Amadumbe phenotypes were evaluated for their nutritional qualities. Like all known tubers, the locally grown Amadume contained high carbohydrate levels, adequate protein and low lipid content. Essential fatty acids (linoleic and linolenic) were identified as components of the Amadumbe lipids. Amadumbe was generally low in mineral content, apart from potassium and magnesium levels that were relatively high. Some anti-nutrients (protease inhibitors, lectin, phenolic compounds, alkaloids, oxalates, phytates, cyanogens and saponin) present in Amadumbe were also identified and quantified. The anti-nutrient levels were generally low and thus may not pose an immediate effect on the health of consumers. Reduction of the anti-nutrients through processing (cooking, frying, roasting) was observed to enhance the nutritional value of these tubers. However, their presence suggests that a steady consumption may lead to toxic levels. Two proteins (Al and B2) with a-amylase inhibitor activity, and a steroidal saponin (gamma-sitosterol) were extracted and partially characterised. The a-amylase inhibitors were extracted and partially purified through ammonium sulphate precipitation and chromatographic fractionation on diethylaminoethyl (DEAE)-Sephacel and Sephadex G-100. The molecular weights of the two inhibitors were estimated to be 17 000 and 19 000 dalton, respectively. The inhibitors were fairly heat-stable, with optimum activity at 40° C? pH 6.0. Both inhibitors showed activity against mammalian a-amylases, but were devoid of activity against fungal amylases. Inhibitor A also showed activity against plant amylases. The steroidal saponin extracted from Amadumbe was characterized through TLC, HPLC, GC-MS, IR and NMR spectroscopic analysis and identified to be gamma- sitosterol, an isomer of beta-sitosterol which is known to have a variety of high biological activity. Studies of the effect of beta-sitosterol on absorptive and digestive enzymes in Sprague-Dawley rats revealed that oral administration of beta-sitosterol had no apparent gross or microscopic lesions in the liver, kidney or small intestine. The administered p-sitosterol significantly decreased serum aspartate aminotransferase (ALT) and alanine aminotransferase (AST) levels. Na+/K -ATPase and intestinal disaccharidases activities were also significantly reduced in beta-sitosterol fed rats. These results do suggest that even though Amadumbe is a neglected crop in South Africa, it is a highly nutritional crop; the consumption of it could be beneficial to diabetic and hypertensive patients.

Conservation agriculture (CA), with its main tenets of 1) minimizing soil disturbance, 2) maintaining residue on soil surface and 3) mixing/rotating crops has been promoted and adopted, to varying degrees, across the globe. It is estimated that eight percent of all arable land is under CA management . While commercially applicable (e.g., Australia, Brazil and the United States), CA has also received attention as a ‘pro-poor’ strategy for ameliorating smallholder agricultural production and a means of climate change mitigation and adaptation. Thus far, research on CA in southern Africa has primarily focused on the factors associated with adoption and agronomic outcomes based on field research in Malawi, Mozambique, Zambia and Zimbabwe. In contrast, Lesotho - a small, landlocked country surrounded by the Republic of South Africa - has received relatively little attention despite its decades-long struggle with severe soil erosion. The extremely high rate of erosion has not only resulted in the proliferation of gullies and the degradation of soil fertility but has also contributed significantly to food security concerns and long term decline in staple crop production. As a result, nearly a quarter of the population is currently in need of food assistance to survive. The average maize yield in Lesotho is stagnant at approximately 400 kg per hectare per year or 95 % less than the typical maize yield in the United States. This research uses household survey data from over 430 households in Botha Bothe district in northern Lesotho to determine the effects of adoption on households in terms of socio-economics and food security and to briefly highlight the potential drivers of and ways to counteract disadoption. This district is of particular interest because different methods of CA (mechanized and manual labor) and technology dissemination (through government-led Extension service and non-governmental organizations) are being deployed concurrently. Results suggest that household demographics, input availability and familiarity with CA all influence its adoption in the short and medium term.

CIP is a web interface that integrates two important information sources into one easy to use interface. The first important source is a climate database that stores and manages queries to a large suite of observational climate data as well as projections of future climate. The second important source of information is an extensive collection of guidance documentation that facilitates the best use of the climate data, it’s interpretation and, importantly, resultant actions. The philosophy guiding CIP is that data is not information and as such only has value when well interpreted and correctly used or applied to appropriate problems.

CIP is targeted at a wide range of users. CIP has been designed to be easy and intuitive to use so as to provide easy and simple access to various climate information. However CIP has also been designed to offer important features such as data downloads that suite users more familiar with climate data. It is our hope that as CIP develops, and you the user provides us with feedback, we will continue to satisfy the needs of a wide range of users.

In many parts of southern Africa, agricultural production is stagnant or even in decline, particularly in subsistence and smallholder agriculture. The reasons are many and debatable, but include lack of suitable inputs for production, environmental constraints and degradation, inadequate agricultural infrastructure, external shocks including volatile markets, and social stresses such as the impacts of HIV/AIDS and growing poverty. As an additional stressor, increasing climate variability and climate change are impacting on agricultural livelihoods since resource-poor farmers are unable to cope with multiple stressors or adapt to climate-related risks. The Kingdom of Lesotho is a typical example of a country considered highly vulnerable to climate-related challenges: as one of the least developed countries (LDCs), it is over-reliant on rainfed agriculture for food production and has a large poor rural population engaged in subsistence farming, which is relatively undiversified.

The Adaptation Network will be offering a series of training courses during 2016 that aim to cater to for different levels of adaptation knowledge and practice. The courses provide a broad foundation that  enable practitioners, officials and activists to gain greater insight into climate science and facilitate effective adaptation processes for members of vulnerable communities.

Climate Smart Agriculture (CSA) describes agricultural practices, approaches and systems that sustainably and reliably increase food production and the ability of farmers to earn a living, while protecting or restoring the environment.

CSA aims to build the food and nutrition security of the rural poor so that farm families have access to enough nutritious food at all times, even in the face of a changing climate.

CSA practices enable farming communities to:

sustainably and reliably increase agricultural productivity and incomes;

adapt and build resilience to extreme weather events and a changing climate; and

where appropriate, contribute to reducing greenhouse gas emissions and concentrations.
