TL;DR: The modelo Integrado de Evaluacion e Intervencion in el proceso de Lucha contra la Desertificación as mentioned in this paper is a participativa metodologia that integrates dimensiones fisico biologicas a socio-economicas and articular diferentes temporalidades and niveles de agregacion.
Abstract: En el ambito internacional –y de la mano de la Convencion Internacional de Naciones Unidas de Lucha contra la Desertificacion y la Sequia (UNCCD por sus siglas en ingles)- se reconoce la importancia de utilizar indicadores y puntos de referencia para aportar cierto rigor en la medicion y comparacion relativas a los procesos de desertificacion. La concrecion de este postulado ha mostrado algunos inconvenientes cuando se abordan las esferas de mayor operatividad, particularmente las de la escala local. Este trabajo busca explorar esas dificultades y propone una metodologia que ha resultado capaz de integrar las dimensiones fisico biologicas a las socioeconomicas y de articular diferentes temporalidades y niveles de agregacion, en un "Modelo Integrado de Evaluacion e Intervencion en el proceso de Lucha contra la Desertificacion". Esta metodologia es ademas participativa y se preocupa por integrar las multiples miradas que se abren sobre este fenomeno.

TL;DR: In this paper, water conflicts are reviewed in four production processes, meaningful to Mendoza and other drylands of central-western Argentina: viticulture, tourism, subsistence production processes and a fourth process that contains the three previously presented: the human settlements production process, urban an rural, in the oases and in the non-irrigated lands.
Abstract: The purpose of this work is to analyze water conflicts by introducing symbolic dimensions not duly recognized or legitimized by the local society. To that end, water conflicts are reviewed in four production processes, meaningful to Mendoza and other drylands of central-western Argentina: viticulture, tourism, subsistence production processes and a fourth process that contains the three previously presented: the human settlements production processes, urban an rural, in the oases and in the non-irrigated lands. Analyzing these processes and conflicts for Mendoza’s case has shown not only how dependent dryland societies are on water resources, but –most significantly – the importance that the ways of controlling and manipulating water have in shaping it social tissue and in consolidating their powers. In other words, Mendoza has been understood as a modern hydraulic society. It is from this outlook that water resource management has proved to be structural not only in the modelling of this dryland society, but also in the shaping of its urban spaces, its oases, as well as in the invisibilizing of the non irrigated spaces. Moreover, water management emerged as a key link between that society and these spaces, and this is why here we read territorial struggles.

TL;DR: The Global Science Conference on Climate-Smart Agriculture (GSCA) as discussed by the authors focused on contributing to economic development, poverty reduction and food security; maintaining and enhancing the productivity and resilience of natural and agricultural ecosystem functions, thus building natural capital; and reducing trade-offs involved in meeting these goals.
Abstract: Background: Climate-smart agriculture (CSA) addresses the challenge of meeting the growing demand for food, fibre and fuel, despite the changing climate and fewer opportunities for agricultural expansion on additional lands. CSA focuses on contributing to economic development, poverty reduction and food security; maintaining and enhancing the productivity and resilience of natural and agricultural ecosystem functions, thus building natural capital; and reducing trade-offs involved in meeting these goals. Current gaps in knowledge, work within CSA, and agendas for interdisciplinary research and science-based actions identified at the 2013 Global Science Conference on Climate-Smart Agriculture (Davis, CA, USA) are described here within three themes: (1) farm and food systems, (2) landscape and regional issues and (3) institutional and policy aspects. The first two themes comprise crop physiology and genetics, mitigation and adaptation for livestock and agriculture, barriers to adoption of CSA practices, climate risk management and energy and biofuels (theme 1); and modelling adaptation and uncertainty, achieving multifunctionality, food and fishery systems, forest biodiversity and ecosystem services, rural migration from climate change and metrics (theme 2). Theme 3 comprises designing research that bridges disciplines, integrating stakeholder input to directly link science, action and governance. Outcomes: In addition to interdisciplinary research among these themes, imperatives include developing (1) models that include adaptation and transformation at either the farm or landscape level; (2) capacity approaches to examine multifunctional solutions for agronomic, ecological and socioeconomic challenges; (3) scenarios that are validated by direct evidence and metrics to support behaviours that foster resilience and natural capital; (4) reductions in the risk that can present formidable barriers for farmers during adoption of new technology and practices; and (5) an understanding of how climate affects the rural labour force, land tenure and cultural integrity, and thus the stability of food production. Effective work in CSA will involve stakeholders, address governance issues, examine uncertainties, incorporate social benefits with technological change, and establish climate finance within a green development framework. Here, the socioecological approach is intended to reduce development controversies associated with CSA and to identify technologies, policies and approaches leading to sustainable food production and consumption patterns in a changing climate.

TL;DR: In this paper, the authors studied the effects of land use and land cover change on the local and regional climate in non-Amazonian regions. And they found that 3.6 million km2 of the original natural vegetation cover in non Amazonian South America were converted into other types of land uses, which is about 4 times greater than the historical Amazon deforestation.
Abstract: Land use and land cover change (LUCC) affects regional climate through modifications in the water balance and energy budget. These impacts are frequently expressed by: changes in the amount and frequency of precipitation and alteration of surface temperatures. In South America, most of the studies of the effects of LUCC on the local and regional climate have focused on the Amazon region (54 studies), whereas LUCC within non-Amazonian regions have been largely undermined regardless their potential importance in regulating the regional climate (19 studies). We estimated that 3.6 million km2 of the original natural vegetation cover in non-Amazonian South America were converted into other types of land use, which is about 4 times greater than the historical Amazon deforestation. Moreover, there is evidence showing that LUCC within such fairly neglected ecosystems cause significant reductions in precipitation and increases in surface temperatures, with occasional impacts affecting neighboring or remote areas. We explore the implications of these findings in the context of water security, climatic extremes and future research priorities.

TL;DR: In this paper, the authors argue that a relational water security framework informed by the capabilities approach offers new ways to consider politics and cultures of water, and also attend to cultural dimensions such as the meanings of water and customary practices that are not easily captured by standardized metrics.
