Description

Resistant varieties are new crop varieties that improve yield production, are resistant to pests and diseases, more tolerant to drought, salinity or other changing or undesirable environmental conditions. Crop plants used within this practice are usually only resistant to a limited number of undesirable characteristics e.g. pests or drought – but usually not both, and some other desirable traits may be lost while others may be strengthened. Hence, careful selection of candidate species must be undertaken. Resistance varieties common in southern Africa include drought resistant maize, sorghum, rice and cowpea (beneficial legume for intercropping) strains, striga (witch weed) resistant sorghum and maize strains, and others all help farmers adapt to changing climate conditions, by being able to farm crops that survive the increasingly variable climate, which can result in less rainfall, or the presence of new pests. Striga results in crop losses totalling over USD 1 billion per year, whereas research has shown that planting climate resilient maize varieties can lead to up to a 25 % increase in crop yields.

Exploring new pest or drought resistant varieties in a regional will require demonstration and testing in ‘test plots’, so extension workers can ensure that the outcomes are aligned with farmers wants/needs/tastes, and so farmers are familiar with the new varieties before they are mainstreamed. Acceptance of new varieties, and any changes is traits will be critical, as resistant varieties is a key intervention for climate adaptation in southern Africa, as they will allow farmers to remain productive for longer under challenging conditions, and while different crops altogether are investigated.

Technical Application

To effectively leverage resistant varieties, the following should be carried out:

  • Step 1: Survey farmers and meet with other local and national level extension officers to determine key interventions required – drought tolerance, prevalence of certain pests, etc.
  • Step 2: Research and meet other local extension officers to discuss best methods applied to the agricultural practice of resistant varieties in the region.
  • Step 3: Talk to the agricultural dealers and seed manufacturers about the varieties being offered and their characteristics.
  • Step 4: Talk to the agricultural research departments about best opportunities under climatic change in your specific area.
  • Step 5: Either independently or in partnership with seed manufacturers, establish test plots of viable resistant varieties in key locations to act as demonstration plots for farmers to visit, observe growth and harvest, and test the outcomes. Many conditions may come into play when attempting to mainstream resistant varieties, including visual aspects, harvesting and processing differences, palatability and taste, etc. All of these issues must be discussed with farmers during testing and roll-out to ensure resources are not wasted with varieties that will fail.

Description

Vaccination is the administration of immunisation injections to animals in order to prevent, control spread of diseases.  Vaccination campaigns involve administration of vaccine doses to a large population over a short period of time. The veterinary services departments or equivalent of respective countries normally gives free vaccinations to the farming community's animals for diseases which are of either economic significance to people's livelihoods or those that maybe of zoonotic importance (communicable to man from animals). These campaigns are usually fully funded by the government, NGOs to reduce disease outbreaks, prevent spread of an outbreak or improve national herd productivity, and are designed to reach as much livestock as possible. In most countries, free vaccinations are offer for the following diseases: Anthrax(-Cattle), Quarter evil or black quarter disease (Cattle), Contagious abortion (Cattle), Rabies (Dogs & Cats), Foot and Mouth Disease(Cattle)_ as per OIE designation in Disease Control Zones.

 For the message to reach farmers, community radios and involvement of traditional leadership can be used to encourage farmers to participate in vaccination campaigns.  This will help to gain trust and confidence from farmers for the campaign to be successful. Vaccination campaigns is a climate smart practice as it ensures a healthy population able to utilize feed efficiently with a reduced population discharge thus reduced GHG emission.

Technical Application

To effectively implement vaccination campaigns:

  • Step 1: Networks that notify farmers about upcoming vaccination campaigns must be established to promote the significance of vaccinating animals across the country. This can be promoted through government bulletins and community radio, utilising extension networks, village level administration, and traditional leadership.
  • Step 2: Vaccination parks for cattle can be set up by veterinary officials to restrain livestock movement that might increase disease spreading.
  • Step 3: Goats and sheep can be vaccinated at their locations where officials will move from one village to another to reach more population.
  • Step 4: Training of personnel is important to ensure that vaccination is carried out before seasonal outbreaks and prevent the spread of disease.
  • Step 5: Commence campaigns one month prior to the season when outbreaks are most common or upon notice of a disease incidence.

Description

Resistant breeds Disease resistance is the reduction of pathogen growth in or in a plant or animal; denoting less disease development in a particular breed than that which is relatively susceptible and is specific to a particular strain of disease or attribute. Breeding resistant breeds  . Resistance” means the animal actively fights infection by various means. Building resistant breeds can be done through selection. Selective breeding, sometimes called artificial selection, where different breeds of animals with desired characteristics or attributes like resistance to. drought, heat, cold, salinity, flood, submergence and pests can be developed by selective breeding and thus able to relatively thrive in some conditions which would otherwise not be able to, e.g. This assists in the reduction of diseases, results in healthier productive animals and reduces risk of secondary infections in livestock. These breeds create a potential for more efficient conversion of feed into meat or diary, and thus a climate smart attribute since by reducing emissions per unit of production (proportionately less faeces are dropped per unit consumption of feed) as well as contributing to food security.,. In the Southern African Development Community (SADC) region, local breeds are more resistant to many of the pests and diseases and may be the best option for some farmers in the Arid and semi-arid areas of the region.

Technical Application

To effectively implement resistant breeds:

  • Step 1: Breed livestock with increased resistance against pathogens or other environmental stressors (heat stress).
  • Step 2: Select animals of higher general disease resistance (resistance to several diseases) using a heritable indicator such as natural antibodies.
  • Step 3: Keep record of good performing animals; unhealthy or easily prone of weak animals should not be used for mating; males should be castrated leaving best specimen to breed in subsequent seasons.
  • Step 4: Breed or inseminate the selected cows with desired or selected bulls or semen of the desired traits.

Description

Species diversification involves a shift from a single species of livestock to more species in an attempt to manage risk and explore more resilient livestock farming options. Species diversification can be introduced in response to changes in local environment/climate conditions, including increasing temperatures, unreliable sources of water and availability of pasture, etc. The aim of this approach is to explore the introduction of species that may be more viable and adaptable in changing local conditions thus improving production levels by keeping animals that will be productive under harsh weather conditions and sustain the quality of the produce. Diversification as a climate smart practice assists farmers with utilising available resources more effectively, e.g. mixing grazers and browsers. Species that react well to changing climatic conditions may cause a shift of demand from grazers to browsers. This practice mitigates disease control, can improve soil fertility and increase water management. Government policies can also influence farmers in diversifying their species with many countries dedicating agricultural research and extension to explore the introduction of different species (e.g. cattle to goats) to assist farmers. It is important that species that are introduced do not have an adverse impact on local fauna or the surrounding environment.

Technical Application

To effectively implement species diversification:

  • Step 1: Research possible species of livestock that may be productive in the climate of the surrounding area and compatible with existing livestock.
  • Step 2: Communicate with national agricultural extension/neighbouring farmers and research to gain an understanding of which breeds have been identified as having potential locally and which are available in the region. Other farmers in the area may have information and experiences to share.
  • Step 3: Inform neighbouring farmers of the potential species that they may be interested in including into their farming system.
  • Step 4: Outline the positive and possible negative aspects of incorporating different species into their system.
  • Step 5: Identify how farmers can access different species and whether they are available at local markets or if these species need to be imported from other areas of the country/region.
  • Step 6: Monitor introduced species to ensure that impacts – positive and negative – are understood.

Benefits

  • Species diversity can assist farmers become more climate resilient by adjusting livestock holdings more adaptable species (camels, goats, etc) as other species can survive on less water and lower feed demands.
  • Diversification may have significant impacts on household food security, income and be more productive.
  • Different species may have traits that are more adaptable to harsh conditions including temperature increases, resistance to disease, drought tolerant, allowing more sustainable productivity (continue to produce milk, eggs meat etc.) and staying in line with market demands during harsher conditions.

Drawbacks

  • Introduction of exotic species can have negative impacts and may push traditional breeds out or have adverse effects on local fodder, water sources etc. if not managed correctly.

Description

The Alternative breeds approach involves substitution of breeds, introducing a new (alternative) breed with a current breed to potentially increase production levels in a farm. Breed substitution involves genetic improvement of cattle and goats especially in dairy farming and meat production. Alternative breeds are introduced in order to ascertain competition between breeds based on health, fertility, performance, profits and management requirements. The substitution breeds are picked because there some traits that may be lacking in current breeds at the farm. For example, some farmers in Malawi who have introduced the Black Australop breed of chicken, either by crossbreeding with local chickens or replacing the local chicken altogether. This breed produces much more meat and lays more eggs, which increases farm production and income. This is a climate smart option as it introduces breeds that may require less water or can manage with lower quality feed – thereby reducing costs, and risks.

Technical Application

To effectively leverage alternative breeds:

  • Step 1: Consult with national agricultural research and extension services to identify adaptable breeds available in the country/region, noting type of traits suitable for the particular ecological zone, and how to access stock. Traits to focus-on include health, milk production, disease tolerance, fertility, economic performance and adaptation to climate change and climate variability. Assisting with sourcing potential alternative breeds is a key role for Extension Officers.
  • Step 2: Before selecting a substitution breed, the current breed must be evaluated to identify traits that are lacking, as well as compatibility. This will help in identifying traits that need to be improved.
  • Step 3: Determine the cost effectiveness of the new breed to the area and or farmer, in terms of feed conversion rates, disease resistance, environmental conservation etc.
  • Step 4: Consistently keep record of the livestock performance and behaviour for discussion with other farmers and extension officers.

Description

Hybridisation is the agricultural practice of genetically manipulating flora and fauna that differ in heredity. Hybridisation and mutations are the main source of hereditary variation and can result in the increased growth rate, manipulated gender ratios, increased yields, sterile animals, improved flesh quality, increase disease resistance and improve environmental tolerance. Intraspecific hybridisation method is used for livestock breeding whereby individuals of different breeds or strains are mated. Distant hybridisation for livestock is difficult to accomplish as hybrids are usually sterile. Hybrid animals are extremely difficult to produce and specialists often spend their careers attempting to create a new breed of animal. Hybridisation is plant species is more common and has a greater success rate than animal species, however successfully creating a hybrid species remains difficult to achieve. Specialists are trained on the gene sequence and different methods for accomplishing hybridisation. The development of hybrid flora and fauna is often undertaken to address a problem or issue. For example, to address socio-economic challenges agricultural researchers may attempt to produce a species of chickens who lay lager eggs or cows who produce more milk. Hybridisation is also applied to address the challenges of a changing climate including producing crops that are more drought resistant. Due to the research and development of these hybrid species they are expensive to access and often not available in remote areas. Traditional breeds are pure individual species with no DNA alterations. They are often endemic to an area and because of this have evolved and adapted to the geophysical area they are found. Thus, traditional breeds are often found in certain areas, and through traditional knowledge have been incorporated into local farming systems for generations. With an increasingly globalised world, it is difficult to maintain distinct traditional breeds as trade in species, seeds etc. is increasingly prevalent. However, with a new focus and dedication of farmers and researchers to explore indigenous knowledge there is an increased focus on reinvigorating the incorporation of traditional breeds of both flora and fauna.

Technical Application

To effectively leverage hybridisation:

  • Step 1: Contact national extension and research as they are often working on developing new species of flora and fauna to meet local challenges including climate variance and introduce them to local farmers.
  • Step 2: Research best methods applied to the practice of hybridisation in the region.
  • Step 3: Meet with national agricultural extension and research staff as well and local breeders to determine desirable characteristics and possible  crossing of livestock differing in heredity. For example, the mating of two different goat breeds to obtain an improved breed.

Description

Rotational grazing is a practice of moving livestock between different units of pasture in regular sequence to allow the recovery and regrowth of pasture plants after grazing. This facilitates management of the nutritional needs of the various types of livestock whilst maintaining pasture productivity. Management of intensive grazing/controlled grazing is a climate smart practice as it results in improved forage harvest, soil fertility, resistance to drought, reduced pasture weeds establishment, reduced wastage of forage and soil compaction.

Rotational grazing can also be combined with cut and carry approaches - when managed correctly; rotational grazing can provide enough forage growth early in the grazing season for producers to harvest feed for later use in some paddocks as rotation continues. Farmers can use temporary fence systems to manage the size of, and access to pastures.

Technical Application

To effectively carry out rotational grazing practices:

  • Step 1: Plan livestock grazing system, based on livestock types, stocking density, pasture crop hardiness and production, rainfall, soils and available alternative pasture fields and space, focusing on the nutritional and forage needs of the animals.
  • Step 2: Use temporary electric fence systems to manage the size of the paddock.
  • Step 3: Move livestock between paddocks every set number of days (two days; one week; one month).
  • Step 4: Assess forage quality and quantity, regulating the acreage of access and control by implementing the electric fence system, which uses electrified fencing to determine which parts of the pasture that the livestock will access.
  • Step 5: Monitoring efficacy of the system, changing rotation periods and extend recovery time for grazed land, if land becomes degraded.

Description

Cut and carry is the agricultural practice of cutting and carrying fodder crops away from the field that they are grown in to feed to livestock. Fodder trees, shrubs or grasses are sources for livestock feed in this practice. Cut and Carry is a key CSA practice where overgrazing is a problem. This practice takes pressure off grazing land at critical periods, reduces land degradation caused by livestock and increases soil organic matter, while still feeding livestock for productive outcomes. This practice can also be used in more intensive livestock production where livestock are kept housed for periods stretching from half a year to a year and improved nutrition is required. However, fodder production can be costly in terms of cultivation, requiring significant management over and above the livestock themselves. Fodder is collected from sites where it grows naturally, or it can be grown in fodder banks, hedges, boundaries, etc. Feeding livestock using this approach can ensure the supply of a large quantity of high quality and palatable fodder within a short time, as well ensuring soil is not disturbed through open grazing systems, thus a good CSA practice. It can be adapted to the farmer’s needs and can provide a way of introducing the farmer to the concept of improving livestock at the same time as conserving soil.

Technical Application

To effectively implement cut and carry systems:

  • Step 1: Cut and carry commences with the cutting of the crop.
  • Step 2: Cut crop when plants are fully mature (vegetative growth and plant sugars are at their peak). This ensures that protein, digestible energy and dry matter percentage are at their highest potential.
  • Step 3: Fodder can be fed directly or dried as hay or preserved as silage to conserve its value and be fed to livestock during the dry season or other critical times throughout the year.

Description

Palatability - referring to plant features or conditions that encourage animals to feed on the plant when given a choice – is important as the ability or willingness of animals to feed on specific forage determines the efficiency of production of animal products. When feed is consumed in larger quantities, depending on its nutritive value, it helps increase milk and/or meat production. Plants with stiff and harsh leaves are generally not palatable to animals, unlike those with softer leaves and grass. The nutritive value of the plant matters when it comes to palatability. Palatability will be determined by the texture, aroma, succulence, hairiness, leaf percentage, sugar content and other factors. Moreover, leaves are more palatable than stems. Palatability of plants can be increased by grazing livestock at the optimal grass growing stage before seed formation, using a High Intensity, Low Frequency (HILF) grazing pattern which allows uniform grazing of pastures and gives an allowance for regrowth and thus overall, uniform soil cover. Addressing palatability is often of greater concern during dry season, when grazing/pasture is less common, and farmers have to rely on stored silage.

Technical Application

Traditional knowledge can also yield positive results in identifying sources of alternative dry season feeds, especially specific types of tree leaves and grasses. In mixed maize and livestock farming system, maize stovers can be utilised for more palatable feed supplements. To effectively improve palatability, the following steps should be carried out:

  • Step 1: Where possible, mix grazing species to include browsers and grazers for uniform pasture use. Mixing livestock will reduce overgrazing on certain plants or plant types, distributing grazing pressure. This is a preventative measure. Over-seeding can be used  to fill in bare patches in fields, improve the density of pasture, establish improved grass varieties and enhance your grass vigour. It’s an easy way to improve an existing old or worn out, diseased or insect prone pasture by planting of grass seed directly into existing pasture, without tearing up the pasture, or the soil.
  • Step 2: Speak to agricultural suppliers as palatability can be improved by enhancing the quality of the feed through addition of feed supplements.
  • Step 3: If using silage from high moisture crops, it may be worth exploring feed flavourants as they mask the odours and flavours of alcohol formed as plant material ferments. Natural flavourants can include garlic, anise and black cumin, but artificial flavours are also available. Ratios for addition to fodder is very low - 0.5 to 1.5 %.
  • Step 4: If using dry grass for feed, chopping and addition of molasses  and other concentrates can improve palatability of drier grasses; however, as it needs to be mixed with urea and water, guidance should be sought in terms of mix-ratios from a veterinarian to ensure that urea intake does not exceed recommended amounts.

Description

Fodder is the agricultural term for animal feed. Fodder trees and shrubs play an important role in bridging the gap between livestock feed requirements and the low quality and quantity of feeds available to many farmers. As well as providing feed or acting as a feed supplement for livestock, fodder trees and shrubs supply other benefits, such as firewood and erosion control. Fodder trees are either grown in-situ, from seed, and others are planted in nurseries and then transplanted to the field at the beginning of the rainy season. The transplanting method can be more successful than the direct planting - as high as 34 % better, but with a 24 % increase in cost per plant. Benefits of using fodder trees and shrubs as a dietary supplement include improved growth, health and reproductive capacity, and increased milk and meat production, mostly through increased protean uptake. Fodder trees and shrubs can be planted as living fences, field boundaries and in tree/shrub plantations. Popular species include African acacias, and Atriplex nummularia, Cassia petersiana, C. mopane, D. cineria, F. albida, Julbernadia paniculata, P. reclinata, Piliostigma thonningii, Swartizia madagascariensis and Trema orientalis.

Farmers of all categories can use this climate smart sustainable approach to produce both livestock and field crops to obtain improve benefits, improving nutrition for livestock animals, improving soil health, reducing cost of livestock feeding, and as a result increasing income

Technical Application

To effectively carry out fodder tree-shrub production using a nursery environment – a covered or exposed separate planting area, often close to the farm so saplings can be tended easily - consider the following steps:

  • Step 1: Identify one or more suitable species for fodder production, looking at suitable climatic, soil requirements, nutritional value and palatability, also considering source-plant (for cuttings) or seed availability.
  • Step 2: Take cuttings of up to *1 metre in length from mature trees, cutting at an angle. Cutting should be planted within three days, and if transported, cutting end should be covered in wax or petroleum jelly.
  • Step 3: Cuttings should be planted in 10 to 15 cm of soil either directly where they will grow or shallower in polythene planting cups.
  • Step 4: Fodder crops should be planted as the rainy starts, providing sufficient water and mobilising enough nutrients to assist rapid growth.
  • Step 5: Harvesting is again species specific*, and it is important to determine if drying prior to feeding, affects palatability or nutritional value.
  • Step 6: Harvesting frequency should also be determined independently*as plants mature to ensure sustainable production that does not stunt long-term growth and productivity.
  • Step 7: The farmer should consider how much fodder needs to be consumed immediately, how much dried as hay, and how much chopped and compressed to make silage.

Length of cutting, period prior to transplantation, and harvest quantities vary from species to species. Seek guidance from an agroforestry specialist or farmers that have experience with the process when selecting species, and how specifically to plant, manage and harvest fodder crops. An important element to understand is the volume of tree or shrub-based fodder each animal will require.

Benefits and Drawbacks

Benefits

  • Fodder trees and shrubs can be highly beneficial sources of feed and nutrition for livestock, augmenting, or completely replacing traditional grazing.
  • Can be utilised when over-grazing has occurred, to allow range land to regenerate.
  • Fodder trees and shrubs add vital nutrients to the soil.
  • Fodder trees and shrubs can provide other benefits, including acting as living fences, and wind-breaks, as well as supplying firewood.
  • Crop rotation is important and fodder crops often act as nitrogen fixers (legumes) as well.
  • Fodder crops can also act as cover crops protecting and maintaining soil quality.

Drawbacks

  • Growing fodder can be laborious.
  • The number of fodder trees and shrubs may be extensive, therefore sufficient land is required.
  • Not only does the gathering of fodder require additional labour, but the harvested crop also requires management.
