“…There are several hundred studies of the potential impacts of climate change on agriculture in the Mediterranean using many different approaches (Iglesias et al 2000;2010b;Quiroga and Iglesias 2009;El-Shaer et al 1997). Studies focus on particular issues (e.g., soil erosion, biodiversity, and farm income), time-frames (e.g., 2020s, 2050s, and 2100), scenarios (e.g., SRES), and spatial scales (from local to regional).…”

This study links climate change impacts to the development of adaptation strategies for agriculture on the Mediterranean region. Climate change is expected to intensify the existing risks, particularly in regions with current water scarcity, and create new opportunities for improving land and water management. These risks and opportunities are characterised and interpreted across Mediterranean areas by analysing water scarcity pressures and potential impacts on crop productivity over the next decades. The need to respond to these risks and opportunities is addressed by evaluating an adaptive capacity index that represents the ability of Mediterranean agriculture to respond to climate change. We propose an adaptive capacity index with three major components that characterise the economic capacity, human and civic resources, and agricultural innovation. These results aim to assist stakeholders as they take up the adaptation challenge and develop measures to reduce the vulnerability of the sector to climate change.

“…Studies that applied crop simulation modeling to estimate CC impacts on African agriculture include: Muchena (1994), Magadza (1994), Makadho (1996) Using results from agronomic models, economic impacts such as changes in area allocations, output supply and resulting changes in prices by crop and region are then estimated. The economic component of these models attempts to optimize consumer and producer welfare subject to climatic and other factors (Easterling et al, 1993;Darwin et al, 1994;Chang, 2002; Kumar and Parikh, 2001;Iglesias et al 1999;Rosenzweig and Parry, 1994). These models suffer from the limitation that the agronomic component fails to account for economic considerations and limitations in human capital and other resources that affect actual farm-level adaptation decisions hence either overestimating damages or underestimating the potential benefits of CC leading to potential biases in economic analyses based on these estimates.…”

The paper analyzed how climate change (CC) has shaped African agriculture in the past and how it might impact on African farm economies in the future and what adaptation strategies African farmers have adopted to cope with these changes. The analyses covered all key farming systems and agro-climates of Africa in 11 countries in which data was collected from over 10,000 farm household surveys. Results provided evidence that African agriculture and the welfare of its rural population are vulnerable to CC. The highest risk of future CC damages is associated with specialized crop and livestock farming (mono systems) particularly under dryland conditions in arid and semi-arid regions. This indicates how difficult it is to achieve an African green revolution under the current high reliance on dryland systems (more than 95% of the land) given predicted harsh future climates (warmer and dryer projections) for most of the dryland areas in PreambleNo doubt our level of awareness and understanding of the climate change (CC) phenomena and their impacts on our planet earth and its inhabitants have significantly improved over the past two decades. There has also been growing attention to and concerns about the consequences of climate change among almost all governments in the world. We remain however with some key uncertainties and gaps of knowledge associated with the complex dynamics between CC, its anthropogenic (human activity) drivers and life on earth including human wellbeing presenting major challenges to present day science and policy making. This is particularly the case in developing countries where efforts and investment levels in scientific research and action programs to better understand and respond to CC continue to be low and the capacity to survive CC vagaries and take advantage of its potential benefits remains consequently very weak.Africa and especially its farming communities and rural population stand out as one clear case of very high vulnerability to CC and its variance.The Synthesis Report of the forth assessment of the Intergovernmental Panel on Climate Change (IPCC) explains how hard it is to find evidence of negative consequences of CC on the world agricultural productivity in aggregate agricultural statistics. One reason is the positive gains from global warming observed in the temperate regions (e.g. North America and Europe) due to reduced risk of frost and longer growing season duration.The other important reason is the fact that world agriculture in general but particularly in temperate regions had witnessed noticeable increases in productivity of most crops as a result of major technological advances (breeding and improved fertility and pest and disease management) (IPCC, 2007 (IPCC, 2007a). This is due to the fact that African economies and the livelihoods of its population are highly dependant on agriculture which is mainly practiced in already harsh climatic conditions (e.g. high temperature, marginal environments, and considerable water stress). It is also important to note tha...

“…La modernización de regadíos tiene efectos económicos, mejora los rendimientos y aumenta el valor de la producción (Perry, C. et al, 2014) porque permite adoptar técnicas, diversificar cultivos y explotar patrones rentables, tiene consecuencias sociales, reduce el abandono de las tierras, fija la población, e impulsa el desarrollo rural (Playán, E. et al, 2013), y climáticos (Cazcarro, I. et al, 2011;Graveline, N. et al, 2014;Iglesias et al, 2000). El regadío también permite el uso de ciertos recursos procedentes de la regeneración y reutilización de aguas (Navarro-Caballero, M.T.…”

ResumenLos mercados de agua son unos instrumentos habilitados desde la Administración para minorar las presiones ejercidas sobre el escaso recurso. Cuentan con una importante regulación jurídica, que ha sido objeto de análisis y estudio por diversos expertos, también se ha evaluado su impacto económico, pero no han sido analizados de forma particular con el mismo interés los aspectos medioambientales que su implementación podría ocasionar tanto sobre las cuencas cedentes como receptoras. Por otra parte, la carestía del recurso hídrico en muchas zonas de España condiciona el uso de aguas regeneradas previamente tratadas, como fuente complementaria al regadío. En este trabajo se plantean los impactos ambientales que la puesta en marcha de un mercado de agua origina con especial énfasis en la transferencia de aguas que proceden de tratamiento y por la realización de infraestructuras. AbstractWater markets are a fitted out instruments from the Administration in order to minimize the applied pressures over this limited resource. They include an important legal regulation. This legal regulation has been analysed and studied from different experts. Moreover, its economic impact has been evaluated. Nevertheless, the environmental aspects about its implementation in the assignment basins and the receptor basins have not been particularly analysed. In the other hand, the lack of water resources in several Spanish zones determines the use of regenerated water previously treated as a complementary source for irrigation. In this work, the environmental impacts of the start-up of a water market are presented. Specifically, the impacts about water transfer from treatment and the development of infrastructures are remarked.
