Urban street trees have myriad proven benefits for communities including providing shade, improving air quality, assisting with stormwater runoff, raising property values, decreasing utility bills, and enhancing the look and feel of communities. While tree inventories provide municipalities with
... [More] vital data to consult when managing the urban forest, creating a complete inventory is a time consuming and resource intensive process. OpenTreeMap provides an easy-to-use public inventorying platform that enables individuals, organizations, and governments to collaboratively contribute to an interactive and dynamic map of a community’s tree population. OpenTreeMap can be used in a single municipality or cover a broader geographic region with many communities, anywhere in the world. [Less]
Daisy is a mechanistic simulation model of the physical and biological processes in an agricultural field. It traces the fate of water, energy, carbon, nitrogen, and pesticides, both above and below ground. The model is able to predict production, environmental impact in the form of leaching, and

OpenFLUID is a software platform for modelling and simulation of landscapes, mainly focused on fluxes (hydrology, pollutant, erosion, ...). This project is developped by the LISAH laboratory at INRA (French National Institute for Agricultural Research )
Supporting actors involved in water resources management
TwoLe Planning Engine is GNU GPLv3-covered free software for supporting Integrated Water Resources Management (IWRM). It provides advanced optimization (stochastic dynamic programming) and simulation engines suitable to allow Decision
... [More] Support Systems (DSS) to explore water management policies for multi-criteria water planning.
The provided optimization and simulation algorithms enable the design and evaluation of water management policies even for multipurpose reservoir networks under different scenarios and goals.
Such kind of mathematical support may be of great importance to allow the actors (stakeholders, decision makers, domain-experts) which are involved in the IWRM problem to move from the complexity of the IWRM modeling to the complexity of the decision problem, relying on automatic tools to explore different scenarios and goals while focusing on the effects of different water management policies.
On the other hand, publicly available software for supporting IWRM decision-making can be viewed as a transparency prerequisite to provide involved actors the ability to understand the implications of the technical apparatus on decision-making and to mitigate unwanted technology-driven biases.
The transparency requirements can be articulated in the very basic demand to be able to freely run the software and to study its complete and non-vague formulation (which needs the public availability of the source code) and in the possibility to correct and improve the software and release improvements to the public. Even if such possibility is usually exploitable only by competent researchers, its importance is vital to raise IWRM actors awareness about the intrinsic fallibility of technical apparatuses and to ensure them the maximum degree of dependability in relying on such software, which is achievable allowing and promoting the maximum degree of public verifiability. These requirements are satisfied only by free software, because the definition of free software is equivalent to them.

The environment modules package provides for an easy dynamic modification of a user's environment via modulefiles. which typically instruct the module command to alter or set shell environment variables such as PATH, MANPATH, etc.
