2.1 ការពណ៌នាដោយសង្ខេបពីបច្ចេកទេស

និយមន័យបច្ចេកទេស:

Mechanized Raised Beds (MRB)-technology improves livelihoods because raised beds lead to significantly reduced costs (30% less water, 20-40% less nitrogen fertilizer) and higher wheat yields increased by 20-30%. MRB-technology helps to do more with less.

2.2 ការពណ៌នាលម្អិតពីបច្ចេកទេស

ការពណ៌នា:

Mechanized Raised Beds (MRB)-technology has been applied by the International Centre of Agriculture Research in Dryland Areas (ICARDA) and national partners in Egypt. Egypt is a water scarce country and 95% of its water comes from beyond its borders. In addition, Egypt is highly dependent on the import of wheat, 50% of the wheat demand is met by import.

In Egypt, water scarcity and mediocre yield are two issues that keep the majority of people working in the agricultural sector in poverty. Water is scarce as the annual precipitation is less than 250mm leading to most farming to be irrigated. The water comes from the Nile river. However, available irrigation water per farmer is rather low due to population growth. Thus, due to clay soil and the use of flood irrigation, water logging and uneven water distribution over the field lead to salinization of the soil, harming the farmer's yields. Furthermore, the latter is caused by the lack of water, insufficient use of fertilizers and the use of relatively low-quality seeds. In particular, fertilizers are expensive leading to an insufficient and poor application of fertilizers.
In effect, the core objective of MRB-technology package is to fit within this context and realize more output with less input, consequently improving involved livelihoods. Indeed, MRB improves farmers' resilience with increased water and nutrient efficiency. The adopters of MRB receive benefits from direct effects such as improvement in their livelihoods, a decreased workload, increased yields and more efficient use of resources (water, fertilizer and seeds).

The first stage research and designing of MRB-technology was done in 2003. Introductions and pilots of the technology were designed together with regular farmers in the Nile Delta-area, from 2010 until 2013. In 2015, MRB-technology was proven beneficial permitting out-scaling. Thanks to the shown potential of MRB-technology and Egypt's reliance on foreign countries for water and wheat, that MRB-technology has become a strong component of Egypt's national wheat campaign. The Egyptian Government aims to cultivate 2 million acres of wheat under MRB-technology, by 2022.

MRB-technology raises the seedbed simultaneously seeding wheat, consequently creating furrows, of which the length depend on the dimensions of the farm- field. The inter- furrow spacing and the width depends on the type of crop planted and on the soil type. The field/terrain may not exceed a slope of 5%. This allows water to infiltrate, reach the end of the furrow and for safe run-off, preventing water-logging. So, to implement MRB-technology, the field might be levelled prior to implementation, but this is often not the case as MRB is designed to local conditions, and most fields already have a slope of less than 5%. The practice of the machine requires a loose soil, so it is required that the field is ploughed prior to seeding, and therefore MRB is not seen as a type of ploughing. If the field preparation is done, a MRB-machine can start seeding and raising the seedbed. Specific characteristics for MRB-technology with respect to conventional seeding, is that seeding and raising seedbeds are done simultaneously. Raising seedbeds mechanically saves 80% of the workload with respect to manually raising seedbeds. The after-harvest practice depends on the farmer preference, as some farmers prefer letting the stubble grazed, while others clear the field. The after-harvest practices are thus independent with respect to MRB.
In addition, to complement the Mechanized Raised Bed, High Quality Seeds are offered. These are beneficial as they yield higher than the regular wheat seeds. Nevertheless, the machine can also be practiced with regular wheat seeds, if the high-quality seeds are found too expensive by the farmer. The High Quality Sees are hybrid, and need to be replaced after three years to ensure high quality.

The technology has significant positive impacts for local farmers as applied water is saved by 25%, water pumping costs decreased by 25%, seed rate reduced by 50%, farming costs decreased by 30%, fertilizer use efficiency increased by 30%, and crop yield increased by 15-30% with respect to conventional farming. On overall, it is estimated that farming under MRB is about 1/3 of the cost with respect to conventional farming. Manually raising seedbeds was considered too expensive due to the required amount of labour. Thus, regular flood irrigation was practiced. Practically, this results in full surface flooding of the field. This has significantly higher evaporation hence increasing salinization, as opposed to furrow irrigation through raised seedbeds. Also, because water is well distributed over the field due to the furrows (reducing water stress and water logging), there is less leaching of the nutrient hence increased nutrient-efficiency. The raised seedbeds allow excess water, in case of a heavy rainfall event or over-irrigating, to safely run-off. These features of better water disposal and reduced evaporation makes MRB-technology well suited with respect to climate change, which leads to more concentrated rainfall events and increased temperature hence increased evaporation. In addition, as MRB prevents e.g. waterlogging it prevents land degradation (e.g. salinization).

Therefore, livelihoods of farmers who have adopted this technology have been greatly improved. Farmers who have adopted MRB, agree that MRB is affordable, easy to apply, improves production and is cost saving. Furthermore, since this technology increases irrigation efficiency , it can mitigate existing upstream-downstream issues in terms of availability, as there is more available irrigation water. Also, as MRB-technology is currently out scaled, it creates employment opportunities since MRB-machines are locally produced from scratch.

មតិយោបល់:

The total costs per acre are estimated to be 44 USD to 64 USD for solely a MRB-machine, so the costs of the High Yield Seeds are excluded.

The purchase of a MRB-machine is commonly done by a community (such as a village). Therefore the realistic costs per farmer of the machine are rather low, as well as the cost per area. The tractor which is used to pull a MRB-machine is the same as has been used before the adoption of a MRB, so this is not an additional cost
The High Yield Seeds are offered with a MRB-machine, but a MRB-machine is build that it can use other seeds as well.

In the short-term investments are weighing relatively more than in the long term with respect to the benefits. However, on the overall, the MRB-technology offers more efficient use of resources, coming down to achieving more output with less input. Thus, highly improving the involved livelihoods.

In the long term the benefits are less positive with respect to maintenance. This is due to the aging of machinery. MRB-machines are estimated to have a life span of 12 years.

MRB significantly contributes to the prosperity of the farmers who have adopted this technology. For farmers, the major advantage of MRB (High Quality Seeds plus the raised seedbeds) is the increased yield.
The adoption of the technology leads eventually to less leaching hence higher fertilizer efficiency. This is also highly valued by the farmers as this translates into less expenses. This advantage of the MRB combined to the increased yield, results in the realization of more income with less expenses, and thus a higher net income.
In Egypt climate change is visibly present and water does not seem to be abundant anymore, the farmers do have increasingly attention for the value of water. MRB increases the irrigation efficiency, therefore this is also observed as a great advantage of MRB.

The increased yield is of great advantage not only for the improved situation of the involved livelihood, but also on national level. Namely, because more yield means less import of food from other countries. This makes Egypt more self-sufficient, and less dependent on other countries. This is particularly relevant with respect to the significant population growth of Egypt.
The increased water availability, because of higher irrigation efficiency is important on a national level. This is certainly important, with respect to trend of increasing the power generation by water (hydraulic power plants), in upstream areas of Egypt.
MRB-technology has led to a local industry. This industry is the manufacturing of MRB-machines. This is on broader level beneficial, because it creates local employment, efficient supply chain, easy and fast access to technical knowledge and gives Egypt an independent position.
MRB improves soil health because salinization is reduced as water is less evaporated and logged.

A current risk of MRB is that many farmers are convinced of the beneficial application of the MRB, which means that there is higher demand. Therefore, there is currently not a sufficient number of MRB-machines. In practice this means that some farmers are not able to use MRB-machine during the essential seeding period. This is possibly followed by tensions between users since the technology is often purchased as communities. Land users found this a weakness of the technology.	This is to overcome if public and private sectors invest in the manufacturing of MRB. This would lead to an increased supply of machine, thus eliminating the deficit of machines.
The cost of the High Yield Seeds is a weakness of MRB-technology. This is because the costs of the seeds are quite high and they contribute significantly to the increased yields. So without the seeds, MRB-technology does not reach its full potential. Farmers dislike the costs of these seeds and the yearly purchasing.	There are investments needed and plans to improve the production of these seeds. The increased supply would lead to reduced costs.

The risk of tensions that are a consequence of the limited availability of the MRB's.	This could be overcome by increasing the production. However, better social cooperation could reduce the tensions between and within communities as well.
The costs of the High Yield Seeds. This is a weakness, because MRB-technology is significantly improved by these seeds, realizing its full potential.	There are investments needed and plans to improve the production of these seeds. This would lead to reduced costs. However, alternatively, other seeds can be used.
