Assessment of locally applied technologies and approaches

Analysis made on 15 study sites (all except Mexico), as the list of technologies was a deliverable. See also DESIRE deliverable 3.1.1.

Exercise 7 was the first exercise conducted together with the external stakeholders, at least in those study sites who invited the external ones only for the 3rd workshop day. The objectives of exercise 7 are:

  • To identify technologies and approaches or other strategies not yet applied but potentially suitable for the local context.
  • To integrate the perspective, knowledge and experience of external stakeholders.
  • To briefly assess already applied and potential solutions.

A predefined table had to be filled by local and external stakeholders separately, assessing the previously identified solutions regarding labour and cost requirements (initial and maintenance), regarding expected economic, ecological and socio-cultural impacts / effectiveness, regarding limiting factors / constraints, and regarding their overall potential for the local context.

In the workshop, fields on 'who already implements?' and on 'what is required that more people will implement' were filled as well, but not documented in the workshop reports. It is therefore not known how much this was actually done.

In the thereafter plenary session participants agreed on the 2-5 most important local and potential solutions, i.e. those with a high potential for the local context. This was sometimes done by voting. The aim was to get a selection of those solutions which would need further assessment with the help of the WOCAT questionnaires on technologies and approaches in WP3.2.

Prioritized solutions

This first rough assessment of SLM measures made in exercise 7 already gives a quite clear understanding of the importance and benefit of the various measures. From a total of 60 priority measures of all study sites, 39 are already applied solutions, whereas 21 are potential solutions. It is noticeable that in some study sites, all promising measures are already applied and in others all are potential measures. Among the first group (all applied) are the study sites of Portugal, Nestos Greece, Crete Greece, Morocco, Tunisia and China, and among the latter (all potential) Djanybek Russia and Chile. Whether this corresponds to countries with a tradition in soil and water conservation or not, is non-conclusive.

Looking at the type of measures selected, results in 19 agronomic, 10 vegetative, 23 structural and 25 management measures, whereas in 17 cases two types of measures are combined. Some conservation technologies were mentioned in several study sites, such as drip irrigation in both Russian, both Turkish and the Crete Greece study sites, but being applied so far only in Konya Karapinar (Turkey) and Crete (Greece). Other measures can also be grouped into similar categories, as presented in table 15, which serves as an overview of the identified measures.

Table 15 indicates a high variety of measures represented. This variety is also reflecting the diversity of degradation and desertification problems prevalent in the study sites. Most of the identified measures are on cropland (66%), 16% on grazing land and 5% on forest land. The rest is on a combination of two of these land use types.

Following some details regarding selected measures groups and their distinct potential and limiting factors in the study sites:

Table 16: Conservation agriculture

Measure Study site Applied /
potential
Limiting factor Potential
minimum and/or correct tillage Spain applied Education and awareness high
no tillage Chile potential Cost, lack of technology, lack of trained labour. good
(needs more research in machinery and chemical products)
no till land management practice Crete applied (not assessed) (not assessed)
nets spread on the soil surface in combination with no tillage Crete applied (not assessed) (not assessed)


Conservation agriculture, entailing minimum soil disturbance, crop rotation and a degree of permanent soil cover, is a widely propagated land management practice in many countries nowadays. In the practices listed above only no or minimum tillage was considered, and only in 3 study sites. This might surprise, but the limiting factors mentioned, indicate that more training, awareness raising and research are required. This is probably also the reason why its potential was not considered in other study sites.

Table 17: Soil nutrient / management

Measure Study site Applied / potential Limiting factor Potential
liquid manure -> biogas -> fertilizer Spain potential easy to apply and supported by farmers and technicians
gypsum addition Nestos applied Gypsum costs (purchase and transport), spreading equipment. Lack of scientific background and verification. Positive (assessment by experts)
land phyto reclamation (sudan grass) Djanybek potential Chemical soil composition constraints Quite profitable (assessment by experts)
green manure Saratov applied Training effective
licorice (Glycyrrhiza) cultivation Saratov potential Chemical soil composition constraints Quite profitable (assessment by experts)


Soil management is a major concern in salinization prone study sites, such as Nestos (Greece), Djanybek and Saratov (both Russia). Vegetative measures are applied or identified as having a potential to improve soil characteristics. Spain identified a potential technology of converting liquid manure into fertilizer through a process where under anaerobic fermentation methane gas is produced and a non contaminating fertilizer. Surprisingly, other study sites did not identify soil fertility improving technologies, although this is often a major concern of land users.

Table 18: Terraces

Measure Study site Applied / potential Limiting factor Potential
terraces and vegetation strips Spain potential Cost, mechanisation, drought (concern that vegetation in the strips will germinate and grow), soil, information, subsidies Important (measure pushed and subsidised by the EU)
land terracing Crete applied (not assessed) (not assessed)
building terraced field China applied Need lots of funds and labour good


Terraces are perhaps the best-known and most spectacular group of SLM technologies, but they are also expensive. They have extensively been applied in the Loess Plateau in China for the last 50 years, where their potential is still assessed positively, but related to high necessary investments of funds and labour.

Table 19: Forest protection and afforestation

Measure Study site Applied / potential Limiting factor Potential
implementation of a Forest Intervention Area (ZIF) Portugal applied Lack of human resources, property structure, few associations, seasonal activities, environmental impacts (chemical use) very positive
prescribed burning Portugal applied Climate conditions, property / land tenure, technical capacity, civil responsibility very positive
primary tracks Portugal applied Area dimension, land tenure, meteo. conditions very positive
reforestation Karapinar applied External stakeholders: high initial and maintenance costs, lack of enough budget allocated to reforestation, lack of pupil education.
Local stakeholders: low precipitation / high evaporation, lack of socio-cultural inheritance
very positive
tree planting Eskisehir applied Legal constraints for forest land, continued technical help, seedling, water scarcity positive
assisted cork oak plantation Morocco applied Costs, difficult to adapt for peasants with weak tradition for cultivation agriculture difficult
planting trees China applied survival rate of trees good


Forest protection is a major concern in Portugal, which is affected by forest fire.

Remarkably, in all but one study sites where afforestation has been identified as a possible solution, it is already applied and assessed to be positive, except for Morocco, where it is considered to be difficult due to a weak cultivation tradition of the pastoral peasants.

Agroforestry is a land use system where trees are grown in association with agricultural crops, pasture or livestock. This system was only mentioned in Morocco and assessed as being difficult due to the same reason as for the cork oak plantations. Agroforestry systems are often not perceived as SLM technologies, especially in areas having a long tradition in it. This might explain their low representation here. However, water availability and competition are also considerable constraints.

Table 20: Livestock and pasture management

Measure Study site Applied / potential Limiting factor Potential
controlled grazing in deciduous woods alternate to grazing rangeland and pasture Italy applied (not assessed) (not assessed)
grazing control Karapinar potential Lack of legislative and management directives, need for extra-pay for man who guards rotation positive
fodder crops production Eskisehir applied Only applicable by livestock producers positive
rangeland resting « tegdeel » Tunisia applied Costs and land fragmentation adapted to the local context
closure against grazing China applied Educational level, concern about food supply good
game ranching Botswana potential Shortage of land and high costs low
improvement of animal production Cape Verde potential Agrarian, cultural, sensitization very positive


Livelihoods of many rural people, especially in dryland areas, are primarily based on pastoral livestock production. Improved management of pasture and livestock relates to changing control of grazing land, regulation of grazing pressure and production of fodder crops. The rotational fodder cultivation practiced in Morocco partly belongs to this group of conservation measures as well. Its main limitation is the consumption of space normally used for grain production.

Table 21: Drip irrigation

Measure Study site Applied / potential Limiting factor Potential
Drip irrigation Crete applied (not assessed) (not assessed)
Drip irrigation Karapinar applied High initial costs, use for only limited number of crops, lack of education about the advantages of technique very positive
Drip irrigation Eskisehir potential Introduction, teaching and convincing the farmers for using the technology, financial support positive
Drip irrigation Djanybek potential Poor quality of irrigation water (filters needed), high risk of demolition and robbery Profitable, water saving, good for vegetable growing, cultural and ecological effects
Drip irrigation Saratov potential Poor quality of irrigation water (filters needed) Costs will be returned in a year (assessment by experts)


Drip irrigation has a high potential in traditional irrigation areas as well as in so far rainfed agriculture systems. Due to its water saving impacts it is suggested as a potential measure in both Russian study sites, where irrigation and salinisation problems prevail. It was not mentioned in the third salinisation study site, which is Nestos, Greece. Limiting factors are low water quality, high initial costs of implementation, and lack of training. Despite these problems, the stakeholders in Karapinar, Turkey, where they already have experience with the technology, assessed the overall potential as very high.

Table 22: Rainwater harvesting

Measure Study site Applied / potential Limiting factor Potential
jessour and tabias Tunisia applied Costs and the lack of workforce Well adapted and very efficient at the local context
cisterns Tunisia applied Costs Well adapted to supplement irrigation
water-proofing (impermeability) of the bottom of water storage pond by artificial alkalinisation Djanybek potential Need of research and of test at small scale positive
rainwater harvesting Botswana applied High initial costs Moderate to high potential as financial assistance can be sought from government


Rainwater harvesting is especially important in dry areas where moisture deficit is the primary limiting factor for production. Costs are stated as a limiting factor, but especially in Tunisia, where it is very dry (150-240 mm/a) and where people have a long-term experience with such structures, it is considered as a well adapted and very efficient measure.

Flood management and dams might also be counted as rainwater harvesting structures at a larger scale. They were identified as a potential structure in Cape Verde, but still requiring technical studies. In China and Tunisia, dams and other recharge units are already applied, but funding is a constraint.

Similarities and differences in assessments made by local and external participants

According to the workshop guidelines it was recommended to conduct the assessment in separate stakeholder groups, i.e. in a local stakeholder group and an external one. In 5 study sites the exercise was done all together in plenary. In 3 study sites it was done either by the researches, or not at all (Crete and Nestos, Greece; Rendina Basin, Italy). In 7 sites the assessment was made in separate groups, whereas in one of them the two groups did not asses the same technologies (Saratov).

The following table gives an overview of the summarized key limiting factors per study site and the similarities or differences in the assessment of the identified SLM strategies.

Table 23: Key limiting factors and similarities & differences in the assessment of SLM strategies, summarized per study site

Study site Summarized key limiting factors Similarities / differences
Guadalentin Basin, Spain
  • lack of confidence in new measures, acceptance, neighbours
  • education and awareness
  • climate, low productive and heavy soils
  • economic support (market, subsidies, commercialisation network)
Assessment done together
Mação and Góis, Portugal
  • lack of human resources (aging), technical capacity
  • property structure, land tenure
  • few associations, civil responsibility
  • finances, investment conditions
  • climate
Assessment done together
Rendina Basin, Basilicata, Italy Not identified Identification of solutions done by DESIRE researchers only
Crete, Greece
  • Lack of law and penalty enforcement
Public participation meeting with voting on problems
Nestos Basin, Nestos, Greece
  • technical (equipment, construction, operation and maintenance)
  • input costs (gypsum, equipment, transport)
  • low envisaged income for farmers
Assessment done by local DESIRE research team only
Konya Karapinar Plain, Turkey
  • climate
  • small land size
  • fuel consumption increase, extra work requirement, maintenance costs
  • competing mulch and fodder
  • lack of legislative and management directives
  • lack of education
Similar assessment, some differences in limiting factors: external participants see need for education. Difference in labour requirement and costs for reforestation (for locals it requires low input, for externals costs are high, budged lacking)
Eskisehir Plain, Turkey
  • legal constraint about status of land
  • financial support
  • technical support
  • availability of organic material, seedlings, appropriate machinery
  • water scarcity
  • limited application (under irrigation only, by livestock farmers)
  • responsibility for maintenance
  • introduction and training
Similar assessment. External participants stress need for introduction and training. Labour and costs for improved grassland are high to locals and medium to externals, although the overall assessment is more positive for the locals. Externals value the short term ecological impact of tree planting slightly higher than the locals. Costs for drip irrigation are valued higher by externals, but also the long term economic and ecological impact is valued slightly higher.
Mamora / Sehoul, Morocco
  • space occupation
  • costs
  • reduced grazing possibilities
  • population resistance, weak tradition for cultivation agriculture
Similar assessment, but not all strategies assessed by both groups.
Fruit tree plantations are considered very costly by the locals, but with a positive impact at the short and long term, whereas externals consider the short term impact only slightly positive. The socio-cultural impacts are valued negative by the locals but positive by the externals. This lies in the fact the land users are pastoralists by origin and would need to stop grazing on their agricultural fields.
Zeuss-Koutine, Tunisia
  • costs
  • lack of workforce
  • land fragmentation
  • rain water scarcity
  • population resistance
Same assessment, costs as main limiting factors for all, mainly structural measures
Djanybek, Russia
  • quality of irrigation water
  • risk of demolition and robbery
  • need for research
  • soil type constraints
Similar assessment, very positive impact perceived for drip irrigation (short and long term, ecological, economic and socio-cultural). Externals value long-term economic impact of land phyto reclamation as very high and profitable.
Novyj, Saratov, Russia
  • training
  • profitability
  • soil type constraints
  • quality of irrigation water
Not assessing same strategies: locals assessed applied and external assessed potential strategies only.
Loess Plateau, China
  • limited funds
  • labour requirement
  • educational level, technical support
  • survival rate of trees, species choice
  • soil fertility
  • food supply (area closure)
Assessment done together
Mopipi, Boteti Area, Botswana
  • mortality rate of cattle
  • shortage of land and water
  • costs
  • livestock sale regulations
Assessment done together
Secano Interior, Chile
  • costs, lack of financial resources
  • lack of trained labour and knowledge
  • lack of technology (machinery)
  • traditions
  • lack of water
  • slope
Similar overall assessment, but differences in impact / effectiveness. Whereas locals value the economic impact of no tillage positive, the researchers and technicians score it negative. The opposite applies for ecological and socio-cultural impacts. The ecological effect of contour ploughing is scored positive by the locals and negative by the externals. The same applies for cattle-crop-system and irrigation technologies, which are scored slightly negative in all aspects by the externals, but positive by the locals.
Ribeira Seca watershed, Cape Verde
  • education, sensitization
  • cultural, resistance to change
  • rainfed agriculture
  • technical studies
  • political
  • financial
Assessment done together


Limiting factors are often costs, education or technical constraints. They should and do cover similar topics as the socio-cultural, economic, political and legal constraints identified in exercise 2. Costs / limited funds are mentioned more often here than in exercise 2. In many study sites it became clear that land users do need support from the government to combat land degradation and desertification, be it direct financial support, or training.

The perception of these limiting factors is mostly very similar between local and external stakeholders. However, external participants more often considered training and awareness raising to be constraint. The similarity or agreement between local and external stakeholders applies also for the assessed impact and potential of the identified measures. If there are differences, they are mainly related to the impact assessment (economic, ecological and socio-cultural) and less to the overall estimation of the potential for the local context. Surprisingly, local stakeholders often rank the impact more positive than external. If this is due to more wishful thinking or other reasons can not be elaborated.
