Understanding Climate change in African Agriculture

Looking in to : Impacts and Potentials in Adaptation-Mitigation Process

Agriculture as a cause of Climate change

According to intergovernmental panel on climate change, Agriculture is one of the world’s largest industries; agricultural land alone covers 40-50% of the world’s land surface. The sector accounts for roughly 14% of global greenhouse gas per year that makes agriculture is a major contributor to climate change (IPCC 2007).

According to the Stern Review, in 2000, about 35% of greenhouse gas emissions came from non-energy emissions: 14% were nitrous oxide and methane from agriculture. Total global greenhouse gas contribution of agriculture from both direct and indirect sources reached up to 32%; the most prominent sources includes: land conversion to agriculture, nitrous oxide released from soils, methane from cattle and enteric fermentation (flatulence-produced methane emissions), biomass burning, rice production, manure, fertilizer production, irrigation, farm machinery and pesticide production. About 74% of total agricultural related greenhouse gas emissions originate in developing countries.

Livestock sector expansion also contributed to overgrazing, land degradation, and an important driver of deforestation in addition to its methane and nitrous oxide emissions from ruminant digestion and manure management, and is the largest global source of methane emissions. Greenhouse gas emissions footprint of livestock sector varies considerably among production systems, regions, and commodities, mainly due to variations in the quality of feed, the feed conversion efficiencies of different animal species and impacts on deforestation and land degradation. Besides the livestock production, the waterlogged and warm soils of rice paddies make rice production system a large emitter of methane from agriculture.

Effect of climate change in agriculture

The cumulative impact of climate will have economic consequences and potentially large implications for the wellbeing and sustainable development of rural populations.  Fundamental to this are a wide range of cross-sectorial impacts affecting health, water and energy resources, ecosystems, and land use. The impacts of climate change to agriculture over the next 50 to 100 years may include:

  • Changing spatial and inter-temporal variability in stream flows, onset of rain days, and dry spells (Strzepek and McCluskey, 2006 ),
  • More frequent floods and droughts, with greater erosion rates from more intense rainfall events and flooding (Agoumi, 2003),
  • Increased crop water requirements from higher temperatures, reduced precipitation and increased evaporation, with likely more negative impacts on dryland than irrigated agricultural systems (Dinar et al., 2009),
  • Positive and negative production and net yield changes for key crops including maize, wheat, and rice, among others, over different time periods, resulting in changes in crop and management choices (e.g. irrigation, crop type) (Kurukulasuriya and Mendelsohn, 2006 ),
  • Potentially lengthened growing seasons and production benefits to irrigated and dryland systems under mild climate scenarios (Thornton et al., 2006 ),
  • Increased heat and water stress on livestock, with possible shifts from agriculture towards livestock management (i.e. stock increases) under increased temperatures with a different mix of more heat resistant species than today and possible benefits to small farms (Seo and Mendelsohn, 2006 ; Dinar et al., 2009).
  • Higher temperatures in arid and semi-arid regions will likely depress crop yields and shorten the growing season due to longer periods of excessive heat.

Climate change will not equally affect all countries and regions, even if Africa represents only 3.6% of emissions, the (IPPC, 2007) report highlighted that Africa will be one of the continents that will be hard hit by the impact of climate change due to an increased temperature and water scarcity. The report pointed out that there is “very high confidence” that agricultural production and food security in many African countries will be severely affect by climate change and climate variability.

Climate change will likely have the biggest impact in equatorial regions such as sub-Saharan Africa. This means that countries already struggling with food security are likely to find they struggle still harder in the future. World Bank (2009) study that focuses on developing countries estimates that without offsetting innovations, climate change will ultimately cause a decrease in annual GDP of 4% in Africa. The Food and Agriculture Organization (FAO) warns that an increase in average global temperatures of just two to four degrees Celsius above pre-industrial levels could reduce crop yields by 15-35 percent in Africa and western Asia, and by 25-35 percent in the Middle East. While an increase of two degrees alone could potentially cause the extinction of millions of domestic and wild species that have a biodiversity and food security potentials.

Adaptation of Agriculture from climate change

The vulnerability of a system depends on its exposure and sensitivity to climate changes, and on its ability to manage these changes (IPCC, 2001). Three intuitive approaches appear to have informed the prioritization of adaptation programs of actions and strategies to climate change, namely: a) social vulnerability approach (addressing underlying social vulnerability); b) resilience approach (managing for enhanced ecosystem resilience); and c) targeted adaptation approach (targeting adaptation actions to specific climate change risks).

Climate change adaptation enhanced by altering exposure, reducing sensitivity of the system to climate change impacts and increasing the adaptive capacity of the system while simultaneously explicitly recognizing sector specific consequences. With this respect, adaptation in the agricultural sector seen in terms of both short-term and long-term actions. The provision of crop and livestock insurance, social safety nets, new irrigation schemes and local management strategies, as well as research and development of stress resistant crop varieties form the core of short-term responses. Long-term responses include re-designing irrigation systems, developing land management systems and raising finances to sustain adoption of those systems.

Safety nets are likely to become increasingly important in the context of climate change as increased incidence of widely covariate risks will require the coverage and financing that these sources may provide. Some of the options for adapting agriculture to climate change have related cost for Agricultural research, Irrigation efficiency, Irrigation expansion and development of Roads.

Improving the use of climate science data for agricultural planning can reduce the uncertainties generated by climate change, improve early warning systems for drought, flood, pest and disease incidence and thus increase the capacity of farmers and agricultural planners to allocate resources effectively and reduce risks. Better use of assessing risks and vulnerability and then developing the safety nets and insurance products as an effective response is already being piloted in some areas with fairly positive results (Barrett et al. 2007).

Mitigation of Agriculture for climate change

Climate change mitigation refers to an anthropogenic intervention to reduce the sources or enhance the sinks of greenhouse gases (FAO, 2011d). In other words, mitigation means taking action to reduce the causes of climate change by limiting the amount of heat trapping gases that emitted into the Earth’s atmosphere. Agriculture could increasing carbon sinks, as well as reducing emissions per unit of agricultural product. The agricultural sector: high mitigation potential with strong adaptation and sustainable development co-benefits.

Mitigation of greenhouse gas emissions in agriculture sector includes reduction of emissions, avoided the emissions and creating sinks that can remove emissions. Lower rates of agricultural expansion in natural habitats, agro-forestry, treating of degraded lands, reduction or using more efficient use of nitrogenous inputs, better management of manure, and use of feed that increases livestock digestive efficiency are some of the major mitigation options in agriculture.

soil carbon sequestration have nearly 90% of agriculture’s climate change mitigation potential could be realized, if carbon markets could introduce to “ provide strong incentives for public and private carbon funds in developed countries to buy agriculture-related emission reductions from developing countries. Soil carbon sequestration by improved land use and management can increase and maintain greater soil Carbon stocks (i.e., sequester C) include a variety of practices that either increase the amount of C added to soils (as plant residues and manure) and/or reduce the relative rate of CO2 released through soil respiration. Soil carbon sequestration practices include: 1) improved grazing land management, 2) improved crop rotations, 3) improved fallows, 4) residue management, 5) reduced tillage, 6) organic matter amendments, 7) restoration of degraded lands, 8) rewetting of cultivated organic soils and (9 Agroforestry. More over using improved nutrient management could increase the plant uptake efficiency of applied nitrogen, reduce N2O emissions, while contributing to soil C sequestration. Agroforestry systems tend to sequester much greater quantities of carbon than agricultural systems without trees. Planting trees in agricultural lands is relatively efficient and cost effective compared to other mitigation strategies, and provides a range of co-benefits important for improved farm family livelihoods and climate change adaptation.

Livestock improvements brought about by more research on ruminant animals, storage and capture technologies for manure and conversion of emissions into biogas are additional contributions that agriculture can make towards mitigating climate change. The anaerobic digestion of manure stored as a liquid or slurry can lower methane emissions and produce useful energy, while the composting solid manures can lower emissions and produce useful organic amendments for soils. To reach the full potential of agriculture in climate change mitigation, transformations are needed in both commercial and subsistence agricultural systems, but with significant differences in priorities and capacity.

In commercial systems, increasing efficiency and reducing emissions, as well as other negative environmental impacts, benefits by increasing carbon sinks, as well as reducing emissions per unit of agricultural product. The sustainable intensification of production, especially in developing countries, can ensure food security and contribute to mitigating climate change by reducing deforestation and the encroachment of agriculture into natural ecosystems. Mitigation of climate change through agriculture is an environmental service that smallholders can provide and is often synergistic with improvements to agricultural productivity and stability.

Climate smart agriculture as a way forward

Climate-smart agriculture is a practice that sustainably increases productivity, resilience (adaptation), reduces/removes GHGs (mitigation), and enhances achievement of national food security and development goals. Efficiency, resilience, adaptive capacity and mitigation potential of the production systems can be enhanced through improving its various components. The future of agricultural production relies on both designing new ways to adapt to the likely consequences of climate change, as well as changing agricultural practices to mitigate the cli-mate damage that current practices cause, all without undermining food security, rural development and livelihoods.

Major transformation of the agriculture sector will be necessary and this will require institutional and policy support. Better-aligned policy approaches across agricultural, environmental and financial boundaries and innovative institutional arrangements to promote their implementation is crucial. Enabling policy environment to promote climate-smart smallholder agricultural transformations is greater coherence, coordination and integration between climate change, agricultural development and food security policy processes.

In farm decision-making and practices, the adaptation and mitigation measures are often the same agricultural practices that also benefit farmers by increasing productivity and resilience. However, there may be important trade-offs too. In these situations, where climate-smart practices entail costs for the farmers and these changes are deemed to bring substantial benefits to the society, the farmers facing extra costs should be compensated through different payment mechanisms, rewarding these farmers for the environmental service they provide. With this prospect climate change creates new financing requirements both in terms of amounts and financial flows associated with needed investments, which will require innovative institutional solutions. In synthesizing potential synergies between adaptation and mitigation in smallholder agricultural transitions.

Fall Armyworm Spodoptera frugiperda (Smith)

5367922

The fall armyworm can colonize over 80 different plant species including many grasses, and crops such as alfalfa, soybean, sorghum, and corn.  Fall armyworm is more likely to be an economic pest in corn and vegetable crops. Fall armyworms are similar in size and shape to other moths in the cutworm family.  They are grayish in color with a wingspan of about 1.5 inches.
Upon arrival to a new field, the female moth deposits egg masses on green plants including important crop hosts.  The eggs hatch about five to seven days after oviposition and the small larvae then begin to feed on plants near the ground or in protected areas such as the whorl of corn plants.  They usually go unnoticed until they are approximately an inch long.  The larva goes through six instars (about 15 to 18 days) before burrowing one to three inches into the soil to pupate.  Adults emerge about one to five weeks after pupation depending on soil temperature.

Adult stage: Adult moths are 20 to 25mm long with a wingspan of 30 to 40mm. Forewings are shaded grey to brown, often mottled with a conspicuous white spot on the extreme tip. Hindwings are silvery white with a narrow dark border. Adults are nocturnal and most active during warm, humid evenings. Females lay eggs in clusters of fifty to a few hundred and can lay up to 2000 eggs in a lifetime. The average adult lifespan is estimated to be 10 days.

Egg stage: Eggs are white, pinkish or light green in color and spherical in shape. Clusters of eggs are frequently covered in moth scales or bristles giving a fuzzy appearance. Eggs are usually laid on the underside of leaves.

Larval stage: Larvae generally emerge simultaneously 3 to 5 days following oviposition and migrate to the whorl. Mortality rate following emergence is extremely high due to climatic factors, predators, and parasites. There are six larval instar stages. In the 2nd and 3rd instar stages larvae are often cannibalistic, resulting in only one larva in the whorl. Mature larvae are 30 to 40mm in length and vary in color from light tan to green to black. Larvae are characterized by several subdorsal and lateral stripes running along the body. Dark, elevated spots (tubercles) bearing spines occur dorsally along the body. Larvae of fall armyworm can be distinguished from larvae of armyworm and corn ear worm by a distinct white inverted Y-shaped mark on the front of the head. They have four large spots on the upper surface of the last segment. Larvae mature in 14 to 21 days after which they drop to the ground to pupate.

Pupal stage: Pupation occurs a few centimeters (2 to 8cm) below the soil surface. Cocoons are generally oval and 20 to 30mm in length. Pupae are reddish brown and measure 13 to 17mm in length. Pupation usually takes 9 to 13 days, following which adults emerge.

  • In optimum conditions the entire lifecycle can be completed in 30 days. Maize crops can normally support two generations.
  • Optimum temperature for larval development is 28۫ C, although the egg stage and pupal stage require slightly lower temperatures.
  • Protracted periods of extreme cold will result in death of most growth stages. The fall armyworm has no diapause mechanism and therefore is only able to overwinter in mild climates and recolonize in cooler climates in the summeConfirmation

Host range

The fall armyworm has a wide range of hosts including maize, rice, sorghum, sugarcane, cotton, alfalfa, peanuts, tobacco, and soybean, in addition to various wild grasses. However, gramineous plants are preferred.

  • Mechanism of damage:Damage is caused by loss of photosynthetic area due to foliar feeding, structural damage due to feeding in the whorl, lodging due to cut stems, and direct damage to grains due to larvae feeding.
  • When damage is important:Severe infestations are uncommon and most plants recover from partial foliar feeding. Under severe infestation complete defoliation of the maize plant is possible. Damage is most severe when worms cause direct damage to the ear. Under severe infestation larvae are frequently observed migrating in large numbers to new fields similar to the true armyworm. Late planted maize and advanced growth stages are more vulnerable to fall armyworm damage.
  • Economic damage:Under severe infestation yield loss ranging from 25 to 50% has been documented.

Monitoring

  • Regularly monitor leaves and whorls for presence of larvae and signs of crop damage.
  • Look for masses of larvae migrating between fields.
  • Pheromone traps can be used to determine incidence of adult moths and disrupt mating during the whorl stages.

Cultural control

  • Plant early to avoid periods of heavy infestation later in the season.
  • Plant early maturing varieties.
  • Rotate maize with a non-host.
  • Reduced tillage methods often result in an increase of natural predators and parasitoids. However, in areas where fall armyworm infestation is high, disking or plowing can effectively reduce the survival rate of pupae in the soil.

Biological control

  • Numerous parasitic wasps, natural predators, and pathogens help to control the population of fall armyworms.
  • The egg parasitoidTelenomus remus is frequently introduced to effectively control fall armyworm and other Spodoptera 

Insecticides

  • Insecticide application should be considered when eggs are present on 5% of seedlings or when 25% of plants show signs of feeding damage. In order to be effective, insecticide application should commence before larvae burrow into the whorls or ears and insecticide spray should penetrate the crop canopy.
  • Insecticides recommended for control ofSpodoptera species include various pyrethroids, carbamates and organophosphates. However, insecticide resistance has been widely reported.

Potential of #Local Food to Improve Food and Nutrition security Okra in #Ethiopia

Okra

Okra, also known as Ladies Fingers, Gombo, Bendi or Gumbo, appears to have originated from West Africa, probably somewhere around Ethiopia, and was cultivated by the ancient Egyptians as far back as the 12th century B.C.

Okra is a member of the Mallow family, related to cotton, hibiscus, rose of Sharon, and hollyhock. Okra or ladies finger is an important vegetable of the tropical countries and most popular in India, Nigeria, Sudan, Iraq, Pakistan, etc. Though virtually not grown in Europe and North America, lots of people in these countries have started liking this vegetable due to the presence of good amount of vitamins.

The plant can be grown throughout the year and resembles cotton in its habit. It is an annual vegetable crop grown in the tropics of the world. It can be grown on all kinds of soils. However, to get the best results, it requires a friable well-manure soil. Okra used in countries like India in huge amount, okra accounts for 60 per cent of the export of fresh vegetables. India exports okra mainly to West Asia, Western Europe and the US. The demand for fresh okra is more in the overseas markets.

Okra pods are available year round. Okra is a very healthy green vegetable that contains many important minerals, vitamins, electrolytes and antioxidants which are essential to good health. Read on, to learn various okra health benefits.

Nutritional value of okra, scientific evidence

Okra is low in calories and is a good source of many nutrients including vitamin B6 and C, fiber, calcium, and folic acid.

Okra is a powerhouse of valuable nutrients. Nearly half of which is soluble fiber in the form of gums and pectin’s. Soluble fiber helps to lower serum cholesterol, reducing the risk of heart disease. The other half is insoluble fiber which helps to keep the intestinal tract healthy decreasing the risk of some forms of cancer, especially colorectal cancer. Nearly 10% of the recommended levels of vitamin B6 and folic acid are also present in a half cup of cooked okra. Like soybean oil, okra seed oil is rich (60 to 70%) in unsaturated fatty acids. Okra mucilage refers to the thick and slimy substance found in fresh as well as dried pods. Mucilaginous substances are usually concentrated in the pod walls.

Health and Medicinal Value: Scientific Evidence

 

  • The fiber content of okra has many high qualities; it helps in maintaining the health of the gastrointestinal tract.
  • Okra helps to reabsorb water and traps excess cholesterol, metabolic toxins and excess bile in its mucilage and slips it out through stool. Because of the greater percentage of water in the bulk, it prevents constipation, gas and bloating stomach problems.
  • This is a very good vegetable for weight loss, as it is a storehouse of health benefits, provided it is cooked on low flame, so that the okra health benefits are retained. This way the invaluable mucilage obtained from okra, is not lost due to high heat.
  • To add volume and bounce to your hair, you can use this hair care tip. Boil horizontally sliced okra, till the brew becomes slimy. Then let it cool, add few drops of lemon to it and use it as a last rinse. This will bring bounce and volume to your hair.
  • The mucilage and fiber present in okra, helps in maintaining blood sugar levels and regulating their absorption in small intestine.
  • Okra facilitates in propagation of good bacteria known as probiotics. These bacteria are similar to the ones proliferated by yogurt in the small intestine, and helps in biosynthesis of vitamin B complex.
  • Protein and oil found in the seeds of okra serves as a good source of high quality vegetable protein. It is rich in amino acids like tryptophan, cysteine and other sulfur amino acids.
  • Okra is a very good laxative, as it helps in treating irritable bowels, healing ulcers and soothing the gastrointestinal track.
  • Okra is good for summer heat and sun stroke treatment.
  • Okra is good for atherosclerosis, and is good for asthma.
  • It can help in prevention of diabetes.
  • Okra Is High In Foliate (Folic Acid) an Important Vitamin for Preventing Birth Defects

 

Okra in ETHIOPIA: Berta Community

Berta is one of the five local ethnic groups found in Benishangulumuz regional state. According to 2007 national census survey (CSA, 2007) report around 173,743 Berta communities found in the region. This local community resides along the Ethiopia Sudan border and they shared same ethnic group in the other side (Sudan) of Ethiopia-Sudan border. Berta community use some special local foods like ocra ( kenkase) , hibiscus (kerkada)and bamboo shoot as a stable food recipe in the area.
