Animals

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.

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.

Vectors are organisms that carry diseases from one living being to another without showing symptoms of the diseases themselves. Some of the most common forms of vectors are blood sucking insects such as mosquitos, fleas, lice, ticks and other similar insects, and rats/rodents. Places such as stagnant water and dumping sites can be ideal habitats for vectors to reside and transmit. The use of natural vector predators can help reduce or eliminate vector populations. The most common vectors in southern Africa are insects (tsetse flies-trypanosomiasis), animals (foot and mouth disease through cattle or people with contaminated shoes), tick-borne relapsing fever (TBRF) and Crimean-Congo haemorrhagic fever (CCHF).  Sanitising the life-cycle of vectors, implementing pest traps and introducing pest predators are means of reducing the spread of disease. The impacts of climate change, especially increased heavy rainfall and higher temperatures can encourage vector populations to grow quicker than normal. Simple strategies to control vectors includes keeping livestock surroundings clean, avoiding livestock access to stagnant water, fencing areas off, restricting animal access to certain locations, can all control biological vectors and assist in reducing vector spread.

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.

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.

Assisted reproduction refers to artificial insemination, where semen is deliberately introduced to fertilise eggs in domestic animals. Artificial insemination helps in obtaining genetic improvements that yield higher production levels. This practice is more expensive but more efficient than natural reproduction. Artificial insemination reduces the risk of disease transmission and injuries or accidents during mating. Sperm duplication can be done from a single ejaculation to make hundreds of doses and distributed across farmers to have variety of breeds rather than off-spring from single bulls. This prevents inbreeding and promotes hybrid vigour among farmers’. In the southern African context, where most grazing is communal, use of bulls to improve breeds can be challenging as it is difficult to adopt a grazing system that will ensure good quality breeds are able to pass their progeny to the next generation, as young and likely non-superior bulls are likely to mate with cows during grazing. To achieve genetic improvement using open grazing requires controlled grazing systems, e.g. by use of paddocks to manage bulls grazing and mixing with cows.

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.

Manure is organic matter that is used as an organic fertiliser in agricultural practices, conditioning and adding nutrients to soil, generally derived from animal faeces. Manure is the best source of fertiliser available to a farmer, as it can be readily available from livestock, and it a more environmentally friendly option over synthetic fertilisers. Animal manure, compost and green manure are the three different types of manure used in soil management. Manure is collected in different forms: liquid manure, slurry manure or solid manure, and treated in different systems depending on its state. Liquid and slurry manure are stored in liquid (slurry) manure storage systems whereas solid manure is stored in sacks in order to allow air and toxic vapours to move in and out, as well as to maintain the moisture content. The manure is collected and treated (as described below) in order to kill pests that may feed on crops during the application period. The manure is further cleaned to remove unwanted substances such as sticks, and large lumps formed in the manure.

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.

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
