Planned Impact

IMPACT SUMMARY (4000 CHARACTER LIMIT)
Most conservation and science projects in the tropics focus on the rain forest biome, neglecting the fact that 50% of the lowland tropics is covered by dry biomes such as dry forests or savannas. These dry areas are home to 30% of the global population, and are hence massively impacted by human activity. This project focuses on the dry forests of the Caatinga region of North East Brazil, which have suffered from scientific neglect, destruction, and lack of conservation attention, with only <1% of these forests included in Brazil's National Protected Area Network. Despite this, the dry forests of the Caatinga house a high level of unique (endemic) plant species that are adapted to the region's severe and erratic droughts. These plants will be a valuable resource as climates change especially for the 15% of Brazil's population that lives in the Caatinga region who depend on these woodlands for ecosystem services and more specific needs such as firewood.
Our project will increase our understanding on how dry biomes contribute to global biogeochemical cycles and how their unique species react to environmental changes, expanding ecological and biodiversity monitoring in Brazil beyond Amazonia and into the Caatinga. The project will build a platform from which Brazil, and Latin America more generally, can monitor more effectively biodiversity and ecosystem services in dry biomes.
We aim to develop whole-system knowledge for the Caatinga to inform responsible management of this unique environment at national and regional political level in Brazil. Brazil has an obligation to monitor its biodiversity and carbon stocks under the Convention on Biological Diversity and the Aichi 2020 Biodiversity Targets, but most previous work has been focused on Amazonia. In particular, this project is relevant to achieving Strategic Goal 3 ('...safeguarding ecosystems, species and genetic diversity through direct interventions such as increasing the coverage, effectiveness and representativeness of protected areas and other area-based conservation measures...') and Strategic Goal 4 ('...safeguarding and enhancement of the benefits of biodiversity and ecosystem services to human societies') of the Aichi targets.
Our project will provide impetus and build capacity for conservation action in the Caatinga. We aim to build bridges between scientists and policy makers who can influence their protection and sustainable management at federal and state level via two policy meetings in Brasilia and Salvador. We will also build environmental science capacity in Brazil for undergraduate and postgraduate students in cutting edge methodologies in biodiversity and ecological science, and involve local communities in the collection of our biodiversity and ecological data. Our project will therefore build long-term capacity to monitor species composition, carbon stock, biogeochemical cycles, vegetation dynamics, and biodiversity loss in the Caatinga.
The project will also benefit local people in NE Brazil through delivery of user-friendly information about plant species useful for ecological restoration, crop wild relatives, minor crops, and useful plants. In the long-term, our science will provide information essentially to successful restoration of Caatinga, for example by a better understanding of the genetic diversity of its plants. Such restoration could have major regional and global ecological effects - for example it has been estimated that large scale dry forest restoration in Latin America could generate up to 8 Pg of carbon storage. In the long-term, the knowledge of biome-level ecological processes gained during the project will enable the sustainable management of ecosystem services that underlie human wellbeing in Brazil and more widely.

Description This project focuses on the dry forests of the Caatinga region of North East Brazil, which have suffered from scientific neglect, destruction, and lack of conservation attention, with only <1% of these forests included in Brazil's National Protected Area Network. Despite this, the dry forests of the Caatinga house a high level of unique (endemic) plant species that are adapted to the region's severe and erratic droughts. These plants will be a valuable resource as climates change especially for the 15% of Brazil's population that lives in the Caatinga region who depend on these woodlands for ecosystem services and more specific needs such as firewood.

The University of Reading (UoR) Nordeste project team has led and contributed to a number of modelling efforts that aimed for an increased understanding on how these dry forest function, in particular under conditions of extreme drought, both seasonally and long-term. Specific emphasis was on the role of plant hydraulic properties, vegetation structure (height, amount of leaf area, and how this affects competition for light, for example), and plant physiological properties. Furthermore, the role of the phenology of the vegetation (i.e. how does the growing season vary between the different tree species, and which environmental factors, such as soil moisture content, affect shedding and onset of leaves). These efforts have led to improvement of existing models that are being used to model the Caatinga ecosystem (in collaboration with the UoR Nordeste team, with international researchers) and to the development of a bespoke Caatinga model, an activity that is still in progress.

Our work has also informed monitoring efforts, already throughout the project, but also planned monitoring of the Caatinga, both on the ground (via instrumentation installed in meteorological towers, or operated manually) and via remote sensing platforms, such as satellites and drones.

The outputs of these models will ultimately be used to improve our understanding on how the Caatinga contributes to global biogeochemical cycles and how its unique species react to changes in environmental factors. This part of the overall Nordeste project has already helped strengthen efforts to monitor and predict ecosystem services in dry biomes, but efforts in this area are still in progress. Ultimately our findings may help forge collaboration between scientists and policy makers to influence protection and sustainable management of the Caatinga ecosystem at federal and state level. We have also helped build environmental science capacity in Brazil for postgraduate students and already established researchers at a number of Institutions throughout semi-arid Brazil (e.g. EMBRAPA and Federal University of Campina Grande).

Title Water and carbon balance outputs of a mechanistic ecosystem model for a Caatinga dryland forest in north-east Brazil 
Description This dataset contains half-hourly output data (for the year 2011) generated by a preliminary version of the Shrubland Ecosystem Assessment (SEcA) model. SEcA calculates the ecosystem processes for a semi-arid shrubland system, for this dataset the model has been configured for a Caatinga ecosystem. The model generates 4 output files, those generating the aerodynamic and surface resistances, state variables, energy balance fluxes, and carbon flux-related outputs. The data provided here relate to model runs with the JULES Farquhar model, with the Sinclair plant water stress switched on. This work was funded by Newton/NERC/FAPESP Nordeste project: NE/N012488/1.

PI Contribution The UoR Nordeste team have been in contact with Dr Marques since last summer about how to best analyse her Caatinga phenology data. Dr Rodolfo Nobrega (Visiting research fellow 'seconded' at UoR, despite being on Imperial College's payroll) has been developing algorithms for Dr Marques to automate the detection of leaf-out and leaf-drop for the many Caatinga species. Dr Marques stayed at my Department for a training secondment from 1 February 2019 until 30 April 2019. We ( Dr Rodolfo Nobrega and myself) are currently assisting with the analyses of her data and preparation of two manuscripts.
Collaborator Contribution Dr Marques is currently at UoR for a 3 month visit (1 February-30 April). She wrote the research proposal to fund this visit and is offering her data and expertise (together with that of Prof. Patricia Morellato) to help develop the Caatinga phenology model, to form part of the overall Caatinga model we are developing. Their knowledge on the Caatinga phenology has already improved the description of the Caatinga phenology in the Tethys Chloris model. This relates to the modelling collaboration with Dr Simone Fatichi of ETH Zurich (since 1 March at the University of Singapore).
Impact Preliminary analyses, shared EGU abstracts, improved Caatinga phenology in the Tethys Chloris model. This involves phenology experts and ecological modellers.

"Development and verification of a new SVAT model for caatinga dry scrub vegetation" NAF\R1\18034. Fellow: Dr Magna Moura, EMBRAPA Brazil, co-I: Prof Anne Verhoef. Two-year visiting fellowship for Dr Moura to work on ecosystem models for Caatinga forest within the University of Reading NORDESTE team. Although we recently heard that this proposal was not succesful, we will try again, e.g. with Brazilean CNP-q. Between1 November 2018 and 30 September 2019 Dr Moura was based at the Department of Geography and Environmental Science, the University of Reading to work with the UoR Nordeste team. The focus has been on analysing and testing the her data, and training her on data-analyses skills and modelling. Unfortunately, a number of data issues were discovered that needed resolving, which has hampered progress to a degree.
Collaborator Contribution Dr Moura is not officially part of NORDESTE project but has offered her Caatinga data (8 years of micrometeorological, soil physical and plant physiological data) and her research site in Petrolinas for the project. PDRA on the project Rodolfo Nobrega and myself are collaborating with Dr Moura and her team to test the bespoke Caatinga model that we are developing. Between1 November 2018 and 30 September 2019 Dr Moura was based at the Department of Geography and Environmental Science, the University of Reading to work with the UoR Nordeste team. The focus has been on analysing and testing the her data, and training her on data-analyses skills and modelling. Unfortunately, a number of data issues were discovered that needed resolving, which has hampered progress to a degree.

Sector Academic/University 
PI Contribution I am currently assisting Manon Sabot (PhD student at UNSW) to implement a multi-component resistance network into her novel ecosystem model. This so that it could be used for the complex Caatinga ecosystem. During the implementation process a number of other issues were discovered relating to the model structure and underlying equation, assumptions, parameters etc. that were fixed with the help of my expertise. This has resulted in a paper that has recently appeared in the New Phytologist. Not yet on the Caatinga ecosystem, but on drought modelling for European forests. The Nordeste grant has been acknowledged in that publication and work on modelling the Caatinga system is progressing steadily.
Collaborator Contribution Manon has developed a model that includes a plant hydraulics and optimisation approach for Caatinga. She visited the UoR Nordeste team in December 2018 and has started to include my multi-component approach. We have been in regular e-mail contact during the course of 2019, and I visited her and her supervisors in Sydney in October 2019. We will meet up again at the EGU in 2020.
Impact Exchange of equations has taken place and a joint EGU abstract has been submitted and accepted. The aim is to co-author papers on the model developments and outputs resulting from this communication. Various presentations have been given on our collaboration during 2019, including at the EGU conference in Vienna and at the first international GEWEX Evapotranspiration meeting that took place from 8-10 October 2019 at the University of New South Wales, Sydney, Australia Output: Sabot, M.

PI Contribution I have been working with the SWAP model development team (Drs Jos van Dam and Joop Kroes) to implement an energy and carbon balance into SWAP, as well as making the SWAP model multi-component, so that it can be used for Caatinga. I have visited the team on four occassions thus far. I am currently waiting for the team to get back to me with updated code.
Collaborator Contribution The SWAP team is providing me with the latest code and coding facilities and is currently adapting the SWAP model so that it can take in my model subroutines.
Impact No tangible outputs yet, but the plan is to test the new SWAP model for a number of sites in the near future and write a paper on this. The SWAP model is used world-wide and this new configuration will make it a much more versatile tool, also of interest for the land surface modelling community
