Technologies for climate change adaptation: agricultural sector
This Guidebook presents a selection of technologies for climate change adaptation in the agricultural sector. A set of twenty two adaptation technologies are showcased that are primarily based on the principals of agroecology, but also include scientific technologies of climate and biological sciences complemented with important sociological and institutional capacity building processes that are required to make adaptation function. The technologies cover monitoring and forecasting the climate, sustainable water use and management, soil management, sustainable crop management, seed conservation, sustainable forest management and sustainable livestock management.
Technologies that tend to homogenize the natural environment and agricultural production have low possibilities of success in conditions of environmental stress that are likely to result from climate change. On the other hand, technologies that allow for, and indeed promote, diversity are more likely to provide a strategy which strengthens agricultural production in the face of uncertain future climate change scenarios. In this sense, the twenty two technologies showcased in this Guidebook have been selected because they facilitate the conservation and restoration of diversity while at the same time providing opportunities for increasing agricultural productivity. Many of these technologies are not new to agricultural production practices, but they are implemented based on assessment of current and possible future impacts of climate change in a particular location. Agro-ecology is an approach that encompasses concepts of sustainable production and biodiversity promotion and therefore provides a useful framework for identifying and selecting appropriate adaptation technologies for the agricultural sector.
The Guidebook provides a systematic analysis of the most relevant information available on climate change adaptation technologies in the agriculture sector. It has been compiled based on a literature review of key publications, journal articles, and e-platforms, and by drawing on documented experiences sourced from a range of organizations working on projects and programmes concerned with climate change adaptation technologies in the agricultural sector. Its geographic scope is focused on developing countries where high levels of poverty, agricultural production, climate variability and biological diversity currently intersect.
Key concepts around climate change adaptation are not universally agreed. It is therefore important to understand local contexts â especially social and cultural norms - when working with national and sub-national stakeholders to make informed decisions about appropriate technology options. Thus, decision-making processes should be participative, facilitated, and consensus-building oriented and should be based on the following key guiding principles: increasing awareness and knowledge, strengthening institutions, protecting natural resources, providing financial assistance and developing context-specific strategies.
For decision-making the CommunityâBased Adaptation framework is proposed for creating inclusive governance that engages a range of stakeholders directly with local or district government and national coordinating bodies, and facilitates participatory planning, monitoring and implementation of adaptation activities. Seven criteria are suggested for the prioritization of adaptation technologies: (i) The extent to which the technology maintains or strengthens biological diversity and is environmentally sustainable; (ii) The extent to which the technology facilitates access to information systems and awareness of climate change information; (iii) Whether the technology support water, carbon and nutrient cycles and enables stable and/or increased productivity; (iv) Income-generating potential, cost-benefit analysis and contribution to improved equity; (v) Respect for cultural diversity and facilitation of inter-cultural exchange; (vi) Potential for integration into regional and national policies and can be scaled-up; (vii) The extent to which the technology builds formal and information institutions and social networks.
Finally, recommendations are set out for practitioners and policy makers:
âą There is an urgent need for improved climate modelling and forecasting which can provide a basis for informed decision-making and the implementation of adaptation strategies. This should include traditional knowledge.
âą Information is also required to better understand the behaviour of plants, animals, pests and diseases as they react to climate change.
âą Potential changes in economic and social systems in the future under different climate scenarios should also be investigated so that the implications of adaptation strategy and planning choices are better understood.
âą It is important to secure effective flows of information through appropriate dissemination channels. This is vital for building adaptive capacity and decision-making processes.
âą Improved analysis of adaptation technologies is required to show how they can contribute to building adaptive capacity and resilience in the agricultural sector. This information needs to be compiled and disseminated for a range of stakeholders from local to national level.
âą Relationships between policy makers, researchers and communities should be built so that technologies and planning processes are developed in partnership, responding to producersâ needs and integrating their knowledge

A text message based weight management intervention
Purpose: This study aimed to determine whether a text message based intervention helped participants maintain or lose weight following completion of a weight loss programme. Low fat diet, regular exercise, breakfast consumption, goal setting and self monitoring are behaviours of weight losers and maintainers (Wing & Hill, 2001). Weight management interventions can be enhanced using mobile telephone technology to deliver support in real time, real world settings (Heron & Smyth, 2010) Methods: In this controlled study, overweight adults completing a weight management programme participated in an additional 12-week text message based intervention (âLEAP Beepâ). Participants (n=17, 7 males; 10 females; mean age 58.3 ± 12.1 years) were allocated daily targets for steps, fruit, vegetable and breakfast consumption. Twice weekly, participants âtextedâ with progress and received practitioner feedback. Pre and post intervention body mass, waist circumference, Body Mass Index (BMI), quality of life (QOL), anxiety and depression measurements were collected and compared retrospectively to a control group (n=17; 4 males, 13 females; mean age 59.1 ± 9.5 years) receiving optional weight checks only (standard care). Paired t tests and Wilcoxon signed ranks tests evaluated differences between pre and post intervention variables. Results: Compared to the control, intervention group body mass, waist circumference and BMI reduced significantly (p=0.006; p=0.0005; p=0.03). QOL and depression scores improved, but not significantly (p=0.134; p=0.228). No difference was found between group anxiety scores (table 1.) Satisfaction surveys showed 100% (n=14) of participants strongly agreed they were satisfied with the overall programme. Conclusions: âLEAP Beepâ resulted in weight and waist circumference losses, improved quality of life parameters and was highly acceptable to participants. Text messaging is a cheap, portable, convenient and innovative contact medium that promotes goal setting, self monitoring and facilitates information exchange with patients. Text messaging inclusive of practitioner feedback opens up increasing possibilities for practitioner to patient support and helps maintain a positive weight outcome following initial weight loss. Further improvements to automation whilst maintaining individual support are necessary to ease practitioner burden

Study of the development of an Io T-based sensor platform for e-agriculture
E-agriculture, sometimes reffered as 'ICT in agriculture' (Information and Communication technologies) or simply "smart agriculture", is a relatively recent and emerging field focused on the enhacement on agricultural and rural development through improved information and communication processes. This concept, involves the design, development, evaluation and application of innovative ways to use IoT technologies in the rural domain, with a primary focus on agriculture, in order to achieve better ways of growing food for the masses with sustainability. In IoT-based agriculture, platforms are built for monitoring the crop field with the help of sensors (light, humidity, temperature, soil moisture, etc.) and automating the irrigation system. The farmers can monitor the field conditions from anywhere and highly more efficient compared to conventional approaches
IT infrastructure & microservices authentication
Mestrado IPB-ESTGBIOma - Integrated solutions in BIOeconomy for the Mobilization of the Agrifood chain project is structured in 6 PPS (Products, Processes, and Services) out of which, a part of PPS2 is covered in this work. This work resulted in the second deliverable of PPS2 which is defined as PPS2.A1.E2 - IT infrastructure design and graphical interface conceptual design. BIOma project is in the early stage and this deliverable is a design task of the project. For defining the system architecture, requirements, UML diagrams, physical architecture, and logical architecture have been proposed. The system architecture is based on microservices due to its advantages like scalability and maintainability for bigger projects like BIOma where several sensors are used for big data analysis. Special attention has been devoted to the research and study for the authentication and authorization of users and devices in a microservices architecture. The proposed authentication solution is a result of research made for microservices authentication where it was concluded that using a separate microservice for user authentication is the best solution. FIWARE is an open-source initiative defining a universal set of standards for context data management that facilitates the development of Smart solutions for different domains like Smart Cities, Smart Industry, Smart Agrifood, and Smart Energy. FIWAREâs PEP (Policy Enforcement Point) proxy solution has been proposed in this work for the better management of userâs identities, and client-side certificates have been proposed for authentication of IoT (Internet of Things) devices. The communication between microservices is done through AMQP (Advanced Message Queuing Protocol), and between IoT devices and microservices is done through MQTT (Message Queuing Telemetry Transport) protocol
