Moisture-dependent physical properties of locust bean (Parkia biglobosa) seeds

Seed moisture content is significant in the handling and processing of seeds. This work therefore determined the physical properties of Locust bean seeds as functions of seed moisture content in the moisture range of 5.9 – 28.2% dry basis. Mohsenin, Stepanoff and ASAE standard methods were used in determining the properties. Increases in seed dimensions vitz length = 10.2±1.0 – 11.3±0.9 mm; width = 8.5±0.8 – 9.1±0.6 mm; surface area = 191.2±24.6 – 208.3±26.3 mm2 ; geometric mean diameter = 7.78±0.49 – 8.12±0.03 and arithmetic mean diameter = 8.06±0.56 – 8.34±0.49 mm were recorded. Seed thickness = 5.49±0.43 – 5.26±0.62 mm; sphericity = 0.75±0.04 – 0.71±0.03; true density = 1251.96±55.5 - 1222±62.16 kgm-3 and porosity = 48.4±2.14 – 41.9±3.78 decreased. Static coefficient of friction increased on plywood (0.5±0.02 – 0.6±0.01), glass (0.4±0.05 – 0.5±0.01) and decreased on aluminium (0.5±0.02 – 0.5±0.04). A data of the physical properties of Locust bean; Parkia biglobosa was developed. This is useful for the design and development of equipment necessary for its handling and processing.

Suppression of root-knot nematode through innovative mustard biofumigation

The nematicidal activity of mustard plant against hatching, migration and mortality of the root-knot nematode Meloidogyne javanica was investigated. In vitro test confirmed that mixing the sandy clay soil mixture with mustard as 4% as a biofumigant significantly reduce the percentage of egg hatching at all different incubation periods 24, 48, 72, 96 and 168 h, compared to control treatment (un-amended mixture soil and eggs in free water). Results indicate that the percentage of egg hatching reduction was 88.5, 90, 81.4, 74 and 69.4%, respectively. Mustard mixed with soil as a biofumigant led to high percentage of larval mortality at the different intervals periods in vitro. The percentage of larval mortality was 94, 100, 90.5, 90.5, and 79.4%, respectively compared to control. Laboratory results confirmed that the highest reduction in egg hatching and larval mortality was obtained after incubation period for 48 h. In vivo experiment reveals that the incorporation of the soil pots with mustard at all different doses used 3, 5% (48 h before nematode inoculation, or soil infestation with nematode), and 5% (one week before nematode inoculation or 7% of soil weight) significantly reduces all the nematode parameters compared to plant treated nematode alone. All nematode parameters i.e. the number of galls per root system, gall index, number of egg masses per root system, as well as number of juveniles per 250g soil showed high reduction with mixing the soil pots with mustard at 5% (one week before nematode inoculation), followed by the same treatment for 48h before nematode inoculation. Mustard application, one week before nematode inoculation, reduced the nematode parameters by 97, 64, 97, and 93%, respectively, compared to control. The percent of chemical components i.e. total sugars, total amino acids and total phenols were markedly enhanced compared to positive and negative control. The highest percentage was obtained with mustard at 5% one week before nematode inoculation by 68.7, 57.3 and 45%, respectively. Finally, we have to conclude that this modified technology is an innovative and can be used efficiently to control Root-knot nematode under organic agriculture and Global GAP agricultural systems instead of these carcinogenic nematicides.

Family agriculture for bottom-up rural development: a case study of the indigenous Mayan population in the Mexican Peninsula

Since pre-colonial times the indigenous communities of Mayan origin in the state of Quintana Roo, Mexico, widely practice home gardens on a sustainable basis as the principal form of family agriculture. This study analyzes the structural complexity, functional diversity and management strategy of these indigenous home gardens in order to attempt to propose recommendations for improved family farming. The Mayan home gardens are structured into three or more vertical layers of multiple plant species of herbs, shrubs and trees, and horizontally into well-defined zones for production of both domestic and wild animals. The home gardens provide multiple services apart from food and nutrition security. For sustainable bottom-up rural development, we recommend the continuation of multifunctional home gardens.

Untersuchungen zu Qualität und Verträglichkeit ökologischer Milch

In der Literatur findet sich eine kontroverse Debatte um eine Differenzierbarkeit ökologischer und konventioneller Produktqualität von Lebensmitteln. Zugleich greifen zahlreiche subjektiv überzeugte Verbraucher zunehmend zu ökologischen Lebensmitteln. Als eines der Kaufmotive wird in vielen Umfragen die Annahme eines höheren Gesundheitswertes und allgemein einer höheren Qualität ökologischer Produkte genannt. Bisher besteht hinsichtlich der Definitionen, Methoden sowie der Einordnung ökologischer Produktqualität keine Einigkeit. Hinsichtlich von Milch zeigen erste Untersuchungen Unterschiede in der inhaltsstofflichen Zusammensetzung. Differenzierungsmarkern aus der Gruppe der Fettsäuren u.a. n-3, CLA sowie spezifischen TFA werden ernährungsphysiologische Wirksamkeit zugesprochen. Wie aber wirkt sich die Produktion in unterschiedlichen Intensitäten sowohl in der konventionellen als auch in der ökologischen Milchviehhaltung auf die Produktqualität aus? Und lässt sich ökologische bzw. biologisch-dynamische von konventioneller Milch differenzieren? Die Arbeit geht der Qualität ökologischer, speziell biologisch-dynamischer Milch nach und prüft in einem ersten Schritt die Verträglichkeit biologisch-dynamischer Vorzugsmilch bei Kindern mit Nahrungsmittelunverträglichkeiten auf Milch. Dabei gliedert sich die Arbeit in drei aufeinander aufbauende Teilbereiche. Das Kapitel 2 „Ökologische Lebensmittel und Produktqualität“ enthält eine Literaturauswertung zur Verwendung des Begriffes „Struktur“ in der Diskussion um die Beurteilung ökologischer Lebensmittel. Die Beschäftigung mit der Begriffsbildung im Zusammenhang mit der Bestimmung ökologischer Produktqualität und den zugrundeliegenden Konzepten sowie der gegenwärtige Entwicklungsstand werden in den folgenden beiden Kapiteln fortgeführt und vertieft. Zudem wird anhand der Arbeitsergebnisse aus Workshops der internationalen Assoziation wissenschaftlicher Institute „Organic Food Quality and Health“ (FQH) und den in diesem Zusammenhang geführten Arbeits- und Abstimmungsprozessen zur weiteren Vorgehensweise bei der Beurteilung ökologischer Lebensmittel dargestellt. Die entwickelten Kriterien dienten zugleich als eine Art Blaupause für die wissenschaftliche Vorgehensweise in diesem Promotionsprojekt und die konkrete Durchführung dieser Studie. In Kapitel 3 „Systemvergleich und Differenzierbarkeit biologisch-dynamischer und konventioneller Milch auf Betriebsebene“ stehen die Ergebnisse und Auswertungen des Systemvergleiches der Milchqualität von konventionellen und ökologischen bzw. biologisch-dynamischen Betrieben in low- bis high-input Orientierung an zentraler Stelle. Der Wissensstand hinsichtlich der Differenzierbarkeit von Milch wird aus der Literatur referiert. Auf Grundlage von u.a. Fettsäuren- und Antioxidantienanalytik wird die Differenzierbarkeit von ökologischer Milch im Sommer wie auch im Winter einer Einordnung und Bewertung unterzogen. Es werden die Möglichkeiten der Differenzier- und Authentifizierbarkeit anhand verschiedener Inhaltsstoffmarker (Fettsäuren, Antioxidantien und Phytansäure) von Milch aus ökologischen und anderen Produktionssystemen dargestellt. Abschließend werden Implikationen für die landwirtschaftliche Praxis in der ökologischen Milchviehhaltung dargestellt. Das Kapitel 4 „Ökologische Milch und Gesundheit“ stellt erste Ergebnisse zur Auswirkung der Produktqualität von Milch auf die Gesundheit des Menschen vor, die in der Zusammenarbeit mit Dr. med. T. Roos entstanden sind. Er führte die Verträglichkeitstestungen im Rahmen unserer Pilotstudie mit Milch unterschiedlicher Herkunft bei Kindern mit Nahrungsmittelallergien durch und konnte eine erstaunlich hohe Toleranz der biologisch-dynamischen Vorzugsmilch im Vergleich zu konventioneller Standardmilch (pasteurisiert, homogenisiert) feststellen. Mit welchen Faktoren in der Produktion und bei der Weiterverarbeitung der Milch dies zu erklären ist, muss in weiteren Untersuchungen zu den qualitativen Zwischenschritten erfolgen. Die Ergebnisse dieser und anderer Studien weisen darauf hin, dass nur gering intensivierte ökologische Milchviehbetriebe, die regelmäßigen Weidegang und möglichst geringe Kraftfutter- und Mais-Fütterung praktizieren, Milch mit einer deutlich differenzierbaren Produktqualität gegenüber durchschnittlicher konventioneller Milch erzeugen. Vor dem Hintergrund wirtschaftlicher Zwänge zu stärkerer Intensivierung geben die vorgelegten Ergebnisse Anlass, die Kriterien der Ausrichtung ökologischer Milchproduktion so zu bestimmen, dass eine „authentische“ ökologische Produktqualität realisiert werden kann. Auch über die ökologische Milchwirtschaft hinaus sind die Ergebnisse dieser Studie von Interesse. Sie hat am Beispiel von Milch in exemplarischer Weise die für eine Qualifikationsbestimmung auch von gesundheitlicher Relevanz erforderliche Kette von Schritten bis hin zum Menschen vollzogen. Die in dieser Studie insbesondere in Bezug auf die Fettsäuren Zusammensetzung gezeigten Qualitätsmerkmale ökologischer und biologisch-dynamischer Milch weisen auf ein auch ernährungsphysiologisch interessantes Alleinstellungsmerkmal der Produktqualität hin, welches die Annahmen gesundheitsbewusster Verbraucher zu bestätigen vermag und dazu verhelfen mag für ökologische Milch und Milchprodukte höhere Preise zu generieren. Im Blick auf die immer wieder neu geführte Diskussion um die Geltung und Konkretisierung der Grundprinzipien des Ökologischen Landbaus kommt dieser Studie besondere Bedeutung zu.

Adaptability of three newly introduced apricot (Prunus armeniaca L.) cultivars to Egyptian conditions

An experiment was conducted in 2013 and 2014 with three newly introduced cultivars of apricot (Prunus armeniaca L.), namely “Antonio Errani”, “Tirynthos” and “Ninfa” to study their performance and adaptability under Egyptian conditions. Results indicated that calculating the chilling hours temperature at or below 15°C was more suitable than temperatures at or below 7.2°C and 10°C. The cultivar with a low chilling requirement started with the opening of vegetative and flower buds earlier when compared to other cultivars. Furthermore, the cultivar Ninfa required less heat units as compared to the other two cultivars. Thus, the accumulated growing degree-days (GDDs) from the time of the flower bud break l until fruit maturity was low in early matured Ninfa cultivar. However, Antonio Errani and Tirynthos cultivars were late in the date of fruit ripening. Meanwhile, there was no significant difference in the opening percentage of vegetative and flower buds, trunk circumference, fruit drop, fruit number and yield weight among cultivars during the two seasons. Conversely, the leaf drop of Antonio Errani cultivar was earlier while Ninfa cultivar started it’s leaf drop later in the two seasons. Tirynthos gave the highest fruit weight, fruit size and fruit surface lightness. Meanwhile, the Antonio Errani cultivar was the highest in fruit firmness and total soluble solids. The appearance and behavior of cultivars under the study varied from one season to another with shoot length, leaf area, percentage of fruit set and acidity. It can be recommended from the present study that, Antonio Errani, Tirynthos and Ninfa cultivars are well adapted under Egyptian conditions. Further, fruits from the cultivars mature early and late in the season and can fulfill the demands of the market.

Soil-less systems vs. soil-based systems for cultivating edible plants on buildings in relation to the contribution towards sustainable cities

Food production and consumption for cities has become a global concern due to increasing numbers of people living in urban areas, threatening food security. There is the contention that people living in cities have become disconnected with food production, leading to reduced nutrition in diets and increased food waste. Integrating food production into cities (urban agriculture) can help alleviate some of these issues. Lack of space at ground level in high-density urban areas has accelerated the idea of using spare building surfaces for food production. There are various growing methods being used for food production on buildings, which can be split into two main types, soil-less systems and soil-based systems. This paper is a holistic assessment (underpinned by the triple bottom line of sustainable development) of these two types of systems for food production on buildings, looking at the benefits and limitation of each type in this context. The results illustrate that soil-less systems are more productive per square metre, which increases the amount of locally grown, fresh produce available in urban areas. The results also show that soil-based systems for cultivation on buildings are more environmentally and socially beneficial overall for urban areas than soil-less systems.

Local Seafood Availability in San Diego, California Seafood Markets

Like many developed coastal cities, San Diego, California has strong geographic and recreational ties to the adjacent ocean, but weak culinary ones. Less than 10% of the seafood consumed in the U.S., and San Diego in particular, is domestic. The popularity and abundance of farmers’ markets and other local markets in San Diego indicates an interest among producers and the public alike in cultivating local, diverse food systems, but this trend has been slower to catch on for seafood. The goal of this project was, therefore, to define and begin to understand the influences on the patterns of locally sourced, domestic seafood availability in San Diego. This study focused on seafood availability in seafood markets including researching market websites and contacting seafood counter managers to determine the general frequency (consistent, occasional, none) at which the markets sold seafood produced by San Diego fishermen or aquafarmers. Seafood market locations were mapped, and demographic and spatial information was gathered for each market’s zip code. The results of the study revealed that only 8% of San Diego’s 86 seafood markets consistently carried San Diego-sourced seafood, and 14% of markets carried it on occasion. Increased density of these local seafood markets was correlated with proximity to the coast, with almost 80% of the markets located within 2 km of the coast. Neither per capita income nor racial diversity was correlated with local seafood market density, indicating that factors contributing to coastal isolation matter more than wealth or diversity in determining where local seafood is sold. The geographic disparity in local seafood availability may be due to a variety of factors, including a small fishing fleet, prevalence of imported seafood, limited waterfront and urban infrastructure needed to support a local seafood system, and a lack of public awareness about local fisheries. Information gleaned from this study can inform further investigation into the influences on local, equitable seafood systems, as well as help consumers, producers and marketers to make informed decisions about seafood purchases and marketing efforts.

Use of farmer-prioritized vertisol management options for enhanced green gram and tomato production in central Kenya

Green grams (Phaseolus aures L.) and tomato (Solanum lycopersicum L) are widely grown in the vertisols of the Mwea Irrigation Scheme alongside the rice fields. Green grams can fix nitrogen (biological nitrogen fixation) and are grown for its highly nutritious and curative seeds while tomatoes are grown for its fruit rich in fibres, minerals and vitamins. The two can be prepared separately or together in a variety of ways including raw salads and/or cooked/fried. They together form significant delicacies consumed with rice which is the major cash crop grown in the black cotton soils. The crops can grow well in warm conditions but tomato is fairly adaptable except under excessive humidity and temperatures that reduce yields. Socio-economic prioritization by the farming community and on-farm demonstrations of soil management options were instituted to demonstrate enhanced green gram and tomato production in vertisol soils of lower parts of Kirinyaga County (Mwea East and Mwea West districts). Drainage management was recognized by the farming community as the best option although a reduced number of farmers used drainage and furrows/ridges, manure, fertilizer and shifting options with reducing order of importance. Unavailability of labour and/or financial cost for instituting these management options were indicated as major hindrances to adopt the yield enhancing options. Labour force was contributed to mainly by the family alongside hiring (64.2%) although 28% and 5.2% respectively used hired or family labour alone. The female role in farming activities dominated while the male role was minimal especially at weeding. The youth role remained excessively insignificant and altogether absent at marketing. Despite the need for labour at earlier activities (especially when management options needed to be instituted) it was at the marketing stage that this force was directed. Soils were considered infertile by 60% but 40% indicated that their farms had adequate fertility. Analysis showed that ridging and application of farm yard manure and fertilizer improved fertility, crop growth and income considerably. Phosphate and zinc enhancement reduced alkalinity and sodicity. Green gram and tomato yields increased under ridges and farm yard manure application by 17-25% which significantly enhanced household income.

The Effect of Climate Variability on Main Components of Cow Milk in Iran

The main purpose of this study is to assess the relationship between six bioclimatic indices for cattle (temperature humidity (THI), environmental stress (ESI), equivalent temperature (ESI), heat load (HLI), modified heat load (HLInew) and respiratory rate predictor(RRP)) and fundamental milk components (fat, protein, and milk yield) considering uncertainty. The climate parameters used to calculate the climate indices were taken from the NASA-Modern Era Retrospective-Analysis for Research and Applications (NASA-MERRA) reanalysis from 2002 to 2010. Cow milk data were considered for the same period from April to September when cows use natural pasture, with possibility for cows to choose to stay in the barn or to graze on the pasture in the pasturing system. The study is based on a linear regression analysis using correlations as a summarizing diagnostic. Bootstrapping is used to represent uncertainty estimation through resampling in the confidence intervals. To find the relationships between climate indices (THI, ETI, HLI, HLInew, ESI and RRP) and main components of cow milk (fat, protein and yield), multiple liner regression is applied. The least absolute shrinkage selection operator (LASSO) and the Akaike information criterion (AIC) techniques are applied to select the best model for milk predictands with the smallest number of climate predictors. Cross validation is used to avoid over-fitting. Based on results of investigation the effect of heat stress indices on milk compounds separately, we suggest the use of ESI and RRP in the summer and ESI in the spring. THI and HLInew are suggested for fat content and HLInew also is suggested for protein content in the spring season. The best linear models are found in spring between milk yield as predictands and THI, ESI,HLI, ETI and RRP as predictors with p-value < 0.001 and R2 0.50, 0.49. In summer, milk yield with independent variables of THI, ETI and ESI show the highest relation (p-value < 0.001) with R2 (0.69). For fat and protein the results are only marginal. It is strongly suggested that new and significant indices are needed to control critical heat stress conditions that consider more predictors of the effect of climate variability on animal products, such as sunshine duration, quality of pasture, the number of days of stress (NDS), the color of skin with attention to large black spots, and categorical predictors such as breed, welfare facility, and management system. This methodology is suggested for studies investigating the impacts of climate variability/change on food quality/security, animal science and agriculture using short term data considering uncertainty or data collection is expensive, difficult, or data with gaps.

Role of microfinance to support agricultural climate change adaptations in Indonesia: Encouraging private sector participation in climate finance

The demands of mitigation and adaptation policies are important to understanding a country’s climate change preparation by providing microfinance in the agricultural sector. This could be seen as a strategy to fight against the challenges of future food security. In 2014, Indonesia established climate change adaptation policies. This legislation aims to pave the way for making actions on climate change adaptation mainstream in national and local development planning. Public and private finance have supported the implementation of the climate actions. However, most funding is still used for mitigation. Adaptation finance needs support, especially in agriculture. This research paper studies opportunities for microfinance to play a role together with existing resources in supporting climate change adaptation in Indonesia. The data was acquired and analysed through a literature review, analysis of case studies and interviews with stakeholders in the climate change-related financial sector. The central findings regarding the opportunity for microfinance to contribute to the existing schemes in Indonesian climate change adaptation finance for agriculture are worthy of the result. This study found that adaptation finance is mostly used for indirect activities. Meanwhile, local communities, and farmers in particular, need directly targeted measures to adapt to climate change. An alternative approach is providing microfinance, insurance and capacity development for farmers to produce high quality agricultural products. This would contribute to optimizing the agri-food value chain, which supports socio-economic development of stakeholders, especially farmers. Hence, microfinance appears to be one potential solution to support direct climate change adaptation actions for the agricultural sector. However, this may not be strong enough to finance the entire needs for agricultural climate actions. Adaptation is contextual, so it has to be grounded in the needs of local communities. Microfinance needs public sectors support as well as other resources from the private sector. In the case of rapid response to disasters, which often destroy the agricultural sector, microfinance should be advantageous in supporting adaptation. However, in reality, it does not work, as it is prevented by regulations. So, this can be an area the public sector can support as a risk-taker as well as by providing initial funds and resources for scaling up efforts.

Assessing the impact of agricultural drought on maize prices in Kenya with the approach of the SPOT-VEGETATION NDVI remote sensing

The high cost of maize in Kenya is basically driven by East African regional commodity demand forces and agricultural drought. The production of maize, which is a common staple food in Kenya, is greatly affected by agricultural drought. However, calculations of drought risk and impact on maize production in Kenya is limited by the scarcity of reliable rainfall data. The objective of this study was to apply a novel hyperspectral remote sensing method to modelling temporal fluctuations of maize production and prices in five markets in Kenya. SPOT-VEGETATION NDVI time series were corrected for seasonal effects by computing the standardized NDVI anomalies. The maize residual price time series was further related to the NDVI seasonal anomalies using a multiple linear regression modelling approach. The result shows a moderately strong positive relationship (0.67) between residual price series and global maize prices. Maize prices were high during drought periods (i.e. negative NDVI anomalies) and low during wet seasons (i.e. positive NDVI anomalies). This study concludes that NDVI is a good index for monitoring the evolution of maize prices and food security emergency planning in Kenya. To obtain a very strong correlation for the relationship between the wholesale maize price and the global maize price, future research could consider adding other price-driving factors into the regression models.

Capacity building activities in rain water harvesting: South Kyrgyzstan

Water and food are fundamental human rights. However, a number of communities in the world suffer due to a lack of these most basic needs. With few alternative economic opportunities, communities in rural and mountainous Kyrgyzstan have to rely mainly on agriculture for their livelihoods.

Ensuring community and agricultural resiliency to climate change: Ceremonial practices as emic adaptive strategies

This paper is an analysis of emic versus etic approaches to climate change resiliency, taking as a case study the traditional ceremony performed by farmers in eastern Flores, Indonesia to rid their fields of rats. This paper begins by providing a theoretical framework discussion on the dominant etic and emic academic research on monsoons and climate change impacts on agriculture. The rat ceremony performed in villages throughout East Flores is a local custom used to rid agricultural fields of pests—often rats—that come from the surrounding forests to feed on the agricultural crops when the rains become erratic. This paper argues that analyzing the rat ceremony through an emic lens allows for better future resiliency to monsoon shifts due to climate change. It is argued that the rat ceremony demonstrates a way in which community resiliency is strengthened by an adaptive approach that supports an already existing community ceremony that emphasizes two essential tenets: community solidarity and coexistence with nature. Both tenets directly promote community resiliency. An explicit emphasis on emic approaches to climate change challenges could help re-define how resiliency is understood and supported within vulnerable communities such as rural villages.

Potential mitigation of midwest grass-finished beef production emissions with soil carbon sequestration in the United States of America

Beef production can be environmentally detrimental due in large part to associated enteric methane (CH4) production, which contributes to climate change. However, beef production in well-managed grazing systems can aid in soil carbon sequestration (SCS), which is often ignored when assessing beef production impacts on climate change. To estimate the carbon footprint and climate change mitigation potential of upper Midwest grass-finished beef production systems, we conducted a partial life cycle assessment (LCA) comparing two grazing management strategies: 1) a non-irrigated, lightly-stocked (1.0 AU/ha), high-density (100,000 kg LW/ha) system (MOB) and 2) an irrigated, heavily-stocked (2.5 AU/ha), low-density (30,000 kg LW/ha) system (IRG). In each system, April-born steers were weaned in November, winter-backgrounded for 6 months and grazed until their endpoint the following November, with average slaughter age of 19 months and a 295 kg hot carcass weight. As the basis for the LCA, we used two years of data from Lake City Research Center, Lake City, MI. We included greenhouse gas (GHG) emissions associated with enteric CH4, soil N2O and CH4 fluxes, alfalfa and mineral supplementation, and farm energy use. We also generated results from the LCA using the enteric emissions equations of the Intergovernmental Panel on Climate Change (IPCC). We evaluated a range of potential rates of soil carbon (C) loss or gain of up to 3 Mg C ha-1 yr-1. Enteric CH4 had the largest impact on total emissions, but this varied by grazing system. Enteric CH4 composed 62 and 66% of emissions for IRG and MOB, respectively, on a land basis. Both MOB and IRG were net GHG sources when SCS was not considered. Our partial LCA indicated that when SCS potential was included, each grazing strategy could be an overall sink. Sensitivity analyses indicated that soil in the MOB and IRG systems would need to sequester 1 and 2 Mg C ha-1 yr-1 for a net zero GHG footprint, respectively. IPCC model estimates for enteric CH4 were similar to field estimates for the MOB system, but were higher for the IRG system, suggesting that 0.62 Mg C ha-1 yr-1 greater SCS would be needed to offset the animal emissions in this case.

Climate change adaptation solutions for the green sectors of selected zones in the MENA region

In this paper, we propose climate adaptation solutions for the green sectors in three different zones of MENA: Egypt’s Delta (irrigated), Karak, in the highlands of Jordan (rainfed), and Lebanon’s Orontes basin (mixed: rainfed-irrigated). We analysed land use and crop intensification, and calculated the economic productivity of water – a critical scarce resource in MENA. By integrating the results with evidence from literature on the potential impacts of climate change and socio-economic factors, we could identify vulnerability levels of the three regions and propose adaptation measures relying of the concept of the “food-water-energy nexus.” While the vulnerability levels are found to be high in the Delta (Egypt) and Karak (Jordan), mainly due to water scarcity and poor adaptive capacity, the vulnerability level is moderate in the Orontes zone (Lebanon) due to a diversified agricultural sector and good market development, coupled with moderate water scarcity. Proposed adaptation solutions range from measures to improve technical efficiency, to measures that encourage economically efficient allocation by use of market forces. For both cases, the development of market opportunities is emphasized to make the proposed measures attractive to farmers.
