Description

Subsurface fertilisation is the agricultural practice of placing compressed balls of fertiliser, known as briquettes, deep in the soil. The balls of fertiliser are known to gradually release nitrogen, feeding the crops with the desired nutrients. This practice is usually carried out in flooded fields and although originally used for urea application in irrigated rice, it can be used with other fertilisers and crop types. Sub-surface fertilisation prevents the loss of nitrogen during floods as the application is placed 7-10 cm deep in the soil, converted to ammonium, which is much less mobile than nitrates. Only about 4% of nitrogen is lost to the environment when applying in the sub-surface, as compared to 35% when nitrogen is applied using the broadcasting application practice. Urea briquettes are small (~2 cm diameter), and home-made manure briquettes – more practical and applicable for crops other than rice – are larger – up to 10 cm in diameter.

This fertiliser application technique is considered climate smart as it maximises fertiliser inputs, increasing productivity and providing a mechanism for adapting to climate change by amending soil properties to remain productive.

Technical Application

To effectively implement subsurface fertilisation, the following should be carried out. Use of briquette machines to produce 1 to 3 grams of briquettes that are larger than conventional fertiliser granules is recommended:

  • Step 1: Prior to application, dig small holes 7 to 10 centimetres deep along planting rows in drained rice paddy or regular field, ideally located in the centre between a location where four plants will be planted.
  • Step 2: Place the briquettes in the whole, below the soil surface, and cover with dug soil.
  • Step 3: Crops should be planted within seven days of fertiliser application.

Following are the main steps for making your own briquettes. Making briquettes leading up to planting is more effective, as they are not stored for too long. A standard briquette machine can be purchased for between USD 3,000 and USD 6,000.

  • Step 1: Collect manure from cow and/or horse waste.
  • Step 2: Allow the manure to moderately dry (so it is possible to handle), but not for extensive periods, otherwise it will degrade. Keep manure out of direct sunlight, or when processing, remove the outer layer before manufacturing briquettes, and do not leave exposed, especially during rainy periods.
  • Step 3: Press manure into briquettes using briquette press machine – see directions below to make your own home-press.
  • Step 4: Allow the briquettes to dry in a cool, dry location, and store for later use.

To make your own large manure briquette press using household items, follow the instructions below:

  • Step 1: Cut the top off a straight-sided 2-litre plastic soft drink bottle at the top of straight side.
  • Step 2: Obtain a tinned food can that is just smaller than the diameter of the bottle. Preferably leave tin un-opened.
  • Step 3: Line the bottle with a plastic bag.
  • Step 4: Place slightly damp manure (cow, horse or both) inside the bag, inside the bottle, filling the space.
  • Step 5: Place tin on top of manure.
  • Step 6: Place small plank of wood on top of the tin.
  • Step 7: Place your foot on top of the piece of wood, and slowly apply pressure to the tin, pressing the manure down, adding more manure if it compresses further than the depth of the tin.
  • Step 8: When the manure will compress no more, remove plank and tin, and draw the compressed manure from the bottle, removing the plastic bag to reveal a cylinder of compressed manure.
  • Step 9: Slice with a sharp knife to discs 2 to 3 cm thick, and use a piece of 2 cm diameter metal or plastic pipe to punch a hole through each disc. Reuse the
  • Step 10: Allow to air dry as individual rings in a cool dry place. As soon as they are strong enough, you can hang the rings on wire to continue to dry. Use in fields within a month of manufacture. The ring increases surface area, and speeds-up the drying process.

Description

Integrated Pest Management (IPM) is the careful consideration of all available pest control techniques and subsequent integration of appropriate measures that discourage the development of pest populations and keep pesticides and other interventions to levels that are economically justified and reduce or minimise risks to human health and the environment, focusing on all practical options for reducing or eliminating pesticides. The practice of IPM for crop protection is widely encouraged, as the practice can enhance crop production and reduce risks associated with use, storage and management of pesticides. The integrated nature of this approach ensures that it is climate smart, as it utilises the best possible options to ensure sustainable productivity, which will in turn allow adaptation to climate change. However, as it may require the use of pesticides as one strategy, the climate-smartness may be affected.

Technical Application

To effectively leverage integrated pest management:

  • Step 1: Identify damage and responsible pest. Regular crop monitoring is important, to ensure early identification. Bottle traps are useful for capturing samples to examine and identify a pest.
  • Step 2: Learn about the pest and host life cycle and biology.
  • Step 3: Monitor or sample environment for pest population.
  • Step 4: Establish action threshold. If aiming to tackle weed infestation, intervention must occur before the weed matures and begins spreading seeds. Some thresholds are high. For example, if dealing with caterpillars, soya beans can tolerate a certain level of defoliation without it impacting crop yield.
  • Step 5: Identify IPM response tactics.
    • Cultural methods –planting crops that are adapted or suited to conditions and responding to their water, nutrient and shelter needs.
    • Physical methods – mechanical weeding, such as mechanical weeding or using organic or plastic mulch to cover the ground to reduce weed presence/success.
    • Genetic methods – selecting modified or adapted pest-resistant varieties.
    • Biological methods – using natural predators, push-pull approaches, intercropping, etc. and use of use of organic pesticides.
    • Chemical methods – considering all levels of toxicity – from pheromone deterrents to conventional pesticides.
  • Step 6: monitoring for ongoing efficacy, and adjustment of tactics where relevant/necessary.  Aiming at all times to use chemical pesticides rationally and as a very last resort.

In the cases where chemical pesticides are used as part of an IPM strategy, the Agri-Intel website is an invaluable resource, which provides detailed chemical management advice: https://www.agri-intel.com.

Description

Flooding irrigation is a practice where water is pumped or allowed to flow into channels passing between crop rows in areas where farmers have level fields. This flooding system is an effective method of managing weeds and pests, preventing the completion of their lifecycles as they are either drowned or isolated from air and sunlight. This practice is applicable in areas where there are favourable climatic conditions with high rainfall amounts; and is not recommended in arid and semi-arid environments. Flooding is controlled using water pumps in order to reduce waterlogging problems, and fields should not be entirely flooded, with surges of periodic flooding used to distribute water and avoid wastage to run-off, evaporation and creation of anaerobic conditions in the soil. Flood waters can be filtered using a fine mesh to control pests and diseases from spreading to neighbouring fields. Sandy soil is not favourable for flood irrigation as it does not evenly distribute water across the field whereas loam and clay soils distribute water efficiently across the field.

It is considered a climate smart practice because it requires less energy, and can promote crop productivity, whilst controlling weeds and pests.

Technical Application

To effectively leverage flooding irrigation:

  • Step 1: prepare the field, digging parallel furrows and raising beds with the excess soil. Crops are planted in beds, and the irrigation water will flow in the furrows.
  • Step 2: Using a pump or gravity fed water storage, allow water to flow into the field, flooding furrows.
  • Step 3: Insert a fine mesh or introduce a hessian sack at the in-flow point to trap weeds and pests.
  • Step 4: Water release should be moderated so as not to flow too fast and erode beds, and too slow such that it remains trapped at the in-flow point.
  • Step 5: Water release can be more effective if released in surges, taking advantage of infiltration rates and capillary action in soil.
  • Step 6: Observe progress. Avoid leaving soil crusts, which will make water rush over.

A sustainable water source must be identified and a pumping/irrigation system should be used.

Benefits and Drawbacks

Benefits

  • A flood irrigation system reduces weed growth and acts as preventive measure against spread of pests and diseases.
  • Requires less energy, so reduces costs. Gravity does the work, so less need for pumping.
  • Flood irrigation can work with lower-quality water because the water doesn’t contact with crop leaves, which is usually a concern with waste water.

Drawbacks

  • Requires larger amounts of water than other types of irrigation – only suitable in wetter climates.
  • Is considered more labour intensive as land must be closely managed, and prepared.
  • Land must be level, or manually/mechanically levelled.
  • Cannot effectively operate in sandy soils.
  • Very clay-heavy soil can easily become water-logged.
  • If not managed properly, can be very wasteful with respect to water.

Description

Short-term reactive practices are control options for pests and diseases once they have reached a level where the economic losses are likely to be greater than the cost of controlling the pest/disease outbreaks and can be used to maintain or increase production. Pests and diseases are better detected at an earlier stage to make it easier to act and prevent severe crop losses and prohibit the spread of pests and diseases throughout the whole field, achieved through regular and systematic field inspections. The practice is considered climate smart as it reduces losses, which in-balance lowers greenhouse gas emissions per tonne of crop produced, it retains agricultural productivity through management of pest infestation and/or disease outbreaks, and is applicable as it can assist farmers adjust to changing climate, and the threat of new and changing pest diseases.

Technical Application

To effectively implement  short term reactive practices:

  • Step 1: Inspecting the crop regularly and systematically by walking through the field following an M-shaped pattern will ensure that the farmer does not just look around the edges, but also inspects in the middle of the field.
  • Step 2: Farmers should carefully examine the crops for any signs of pests/diseases. They may be able to identify the presence of pests or disease through observing the following:
    • If the plant is wilted.
    • Are the leaves more yellow than usual?
    • Are the crops smaller than usual?
    • Do the leaves have spots?
    • Have parts of the plan died?
  • Step 3: Once the foreign specie has been identified, the farmer should employ a method to eradicate the issue thoroughly and immediately.

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

Cultural pest control practices Are pest control management measures to control pests (insects, diseases, weeds) by manipulation of the environment or implementation of preventive practices including using plants that are resistant to pests, raising the mowing height of pastures to shade out weeds, aerating pastures to reduce compaction and plant stress. Several beneficial cultural practices can meet both demands, helping with pest and disease control and minimizing the use of toxic chemicals. In the insect pest management context, cultural practices may be considered as specific crop production practices that may be implemented either in the initial stages of the organic farm plan but also as a continuous plan to reduce the likelihood of insect pest infestation to a crop and damage. They form part of the Integrated Pest management (IPM) Practices and are based on tactics to disrupt pest infestation of crops by having the crop unavailable to pests in space and time, making the crop unacceptable to pests by interfering with host preference or location, reducing pest survival on the crop by enhancing natural enemies, altering the crop’s susceptibility to pests. The tactics or methods used in IPM include one or a combination of the following: Cultural control (crop rotation, use of locally adapted or pest resistant/tolerant varieties, sanitation, manipulating planting/harvest dates to avoid pests). Cultural pest control or IPM results in reduced pests/diseases and increased yields and is a climate-smart practice as its emphasis of prevention helps to control pests and diseases before they occur;  its continuous long-term practices without use of chemicals encourage healthier and more pest resilient crops and landscapes, encouraging the use of beneficial insects  making it an adaptation benefit. The possibility of prediction and recognition of pest outbreaks enables earlier management consultations and decisions. The reduction in losses results in lower GHG emissions per tonne produced.

Technical Application

To effectively implement continuous long-term use of cultural practices, the following steps, as part of the Integrated Pest Management (IPM)  should be carried out, but before taking any pest control action, IPM first sets an action threshold, a point at which pest populations or environmental conditions indicate that pest control action must be taken:

  • Step 1: Inspection. The cornerstone of an effective IPM program is a schedule of regular inspections. This should be regular to identify any new visitors to your crop.
  • Step 2: Preventive Action: regular inspections reveal vulnerabilities in your pest management program, steps can be taken to address them before they cause a real problem. One of the most effective prevention measures is exclusion, i.e., performing structural maintenance e.g by closing potential entry points revealed during inspection thereby physically keeping pests out and hence reducing the need for chemical control.
  • Step 3: Identification: Different pests have different behaviours. By identifying the problematic species, pests can be eliminated more efficiently and with the least risk of harm to other organisms. Professional pest management always starts with the correct identification of the pest in question.
  • Step 4: Analysis: Once you have properly identified the pest, you need to figure out why the pest is in your facility, e.g. food debris or moisture accumulation that may be attracting it? What about odors, through floors or cracks, etc.
  • Step 5: Treatment Selection: Cultural or IPM stresses the use of non-chemical control methods, such as exclusion or trapping, before chemical options. When other control methods have failed or are inappropriate for the situation, chemicals may be used in least volatile formulations in targeted areas to treat the specific pests- use the right treatments in the right places, and only as much as you need to get the job done.
  • Step 6: Monitoring: Constantly monitoring your facility for pest activity and facility and operational changes can protect against infestation and help eliminate existing ones. Your agricultural extension officer can assist you in technical advice to keep pests away.
  • Step 7: Documentation: Up-to-date pest control documentation is important and could include scope of service, pest activity reports, service reports, corrective action reports, trap layout maps, lists of approved pesticides, pesticide usage reports and applicator licenses

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.

  • 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.

Benefits and Drawbacks

Benefits

  • Alternative breeds are used to improve the genetic qualities of livestock.
  • This agricultural practice improves biological diversity, ensures food security, increases farm income and most importantly reduces risk as cross breeds in future will be more resilient to climatic variations.

Drawbacks

  • Requires research to identify suitable breeds.
  • Livestock will require frequent monitoring to ensure cross-breeding is yielding required results.
  • Replacement breeds should also be monitored to ensure they are adjusting to the local conditions.
