Short-term Farm Level Adaptations of EU15 Agricultural Supply to Climate Change
Assessing climate change impact on agriculture is a complex task involving a wide range of economical and physical processes, leading to significant uncertainties. At European scale, climate change impacts on agricultural supply have been appraised to be of relatively less important driver by the end of century compared to other global drivers. However these diagnoses are incomplete due to a limited representation of both spatial heterogeneity in important determinants of agricultural supply (soil, management practices and producer typology) and fine scale processes such as farm scale autonomous adaptation. We propose a complementary approach based on a modeling framework including a spatially explicit representation of productivity and producer behavior with regard to heterogeneity in soil, climate, and producer socio-economic context to appraise climate change impacts including autonomous farm-scale adaptations of EU15 agricultural supply to climate change. Our results suggest that without accounting for autonomous adaptation European agricultural supply may have interesting resilience properties at an aggregated scale despite significant heterogeneity at smaller resolution. Accounting for autonomous adaptations result in significant yield gains, and may lead to (i) a significant increase in the relative profitability of crops compared to other land-covers, thus possibly increasing its agricultural land-use share over other land covers, and (ii) an increase in total European production which may have impacts on agricultural goods markets, thus highlighting the need for integrating fine scale processes such as autonomous adaptation.Environmental Economics and Policy, Farm Management,
QUANTIFYING THE HETEROGENEITY OF ABATEMENT COSTS UNDER CLIMATIC AND ENVIRONMENTAL REGULATION CHANGES: AN INTEGRATED MODELLING APPROACH
We present here preliminary results of an integrated modelling approach combining a crop model (STICS) and an economic model (AROPAj) of European agricultural supply. This modelling framework is designed to perform quantitative analysis, regarding climate change impacts on agriculture and more generally the interactions between soils, land use, agriculture and climate integrating physical and economical elements (data, process, models). It explicitly integrates an agricultural diversity dimension with regards to economic set of choices and soil climate spatial variability. First results are given in term of quantitative analysis combining optimal land allocation (economic optimality) and “dose-response” functions related to a large set of crops in Europe, at the farm group level, covering part of the European Union (EU15). They indicate that accounting for economical and spatial variability may impact both regional aggregated scales results.Crop Production/Industries, Environmental Economics and Policy, International Relations/Trade, Land Economics/Use, Resource /Energy Economics and Policy,
Water Use for Hydraulic Fracturing: A Texas Sized Problem?
The state of Texas could face a 2.7 trillion gallon shortfall of water by 2060. Hydraulic fracturing (HF) requires large amounts of water for each well. Tax incentives should be offered to companies that substitute brackish groundwater for fresh. However, HF technology is not the only or even the most significant contributor to the longstanding problem of water stress in Texas. Accurate and transparent data reporting on all water consumption (irrigation, municipal use, mining, and others) and policy changes to address inefficient water use practices in all sectors are needed. Without broad water regulation efforts the state will continue to suffer from overuse of its most precious resource—water
Avoiding the Mistakes of the Past: Rejecting Protectionism and Embracing the Global Economy
The “Great Recession” of 2008 was the greatest global financial crisis since the Great Depression. It led to the bankrupting of businesses, caused credit markets to dry up, imploded the housing market, and led to a near collapse of global trade. The plunge in trade that occurred between the second quarter of 2008 and the third quarter of 2009 was the steepest fall of world trade in recorded history. By rejecting protectionism, and by embracing the global economy through initiatives like NAFTA and the TPP, the U.S. can foster increased job growth and economic prosperity for its own citizens, and for individuals around the globe
Water Use in the Eagle Ford Shale: An Economic and Policy Analysis of Water Supply and Demand
The Eagle Ford Shale is a massive geologic formation
located in South Texas
spanning 30
Texas counties
from
Brazos County in the north east to Webb County in the southwest
. With the advent of hydraulic fracturing (HF) and
horizontal drilling, over 200 operators have been able to tap into previously inaccessible shale reserves to p
roduce
abundant amounts of oil and gas.
The oil and gas
proliferation
in the Eagle Ford
has seen
exponential growth
, and
production is not anticipated to decline until 2025. In addition,
a typical
HF
well in the Eagle Ford
is estimated to
consume
about 13
acre
-
feet
of water for
a
standard
5000
foot
lateral
.
Approximately 90% of water for HF comes
from fresh groundwater aquifers.
This interaction
of HF and
water consumption
is of primary importance from a
poli
tical
and
economic perspective. This
s
erves as t
he focal point of our
report.
Using the tools of statistics, our research considered the groundwater
consumption
trends within
the
Eagle Ford
counties
using water consumption data
of
municipal, irrigation, mining
(oil and gas)
and other
categories over a
span of four years
. This
analysis showed
that
fresh groundwater
is being consumed
at about 2.5 times
the
groundwater recharge rates
.
Furthermore,
irrigation is using more water than all other water
-
consuming
categories
combined.
Thus, the water problem
reaches well beyond the use of fresh grou
ndwater for mining
.
With respect to likely requirements of water for HF,
we posited this question:
“
W
ill technology bail us out?”
Retrofitting learning curves to our data
for water uses and
the
length of
the well
la
teral
,
we find that after i
nitial
improvements in water us
age, the technology appears to have stabilized.
This, coupled with massi
ve irrigation
water consumption
suggests
that
technology will not be a major
source of water savings
in the long run.
Instead,
we must look to better public policies
.
From a policy perspective,
the status quo for
groundwater u
se
is governed
by the
Rule of Capture and the
oversight of groundwater conservation districts
(GCDs)
. T
here exists a real conflict as large
-
scale water users are
competing for a diminishing aquifer resource with no market signals of increasing scarcity. In addition,
groundwater wells drilled
in connection with oil and gas exploration are exempt from
GCD
per
mitting
requirements
and
receive a de facto “free pass” to water for HF.
Likewise, limita
tions imposed on irrigation users
by the GCDs are rarely binding, so these users
usually
get a free pass as well.
Our analysis leads us to
three
basic
policy
recommend
ations
. The first
involves
mandatory reporting
of all
groundwater uses by all classes of water use
r
s.
Currently, government agencies and the public lack basic
information on
actual water
consumption;
t
his policy seeks to relax that knowledge gap and bring
transparency.
Second
, we propose incentivizing oil
and gas companies to substitute brackish
groundwater for fresh ground
water.
Our proposal
calls for
a severance tax reduction
for tho
se companies limiting
fresh
groundwater
use
for
HF in the
Eagle Ford.
In
addition to a temporary reduction in the
severance tax, these companies c
ould be recognized
by the
RRC and
possibly
the TCEQ for their
environmental stewardship
with a
“
Green Star
”
designation.
Our t
hird
,
most
heterodox
and long
-
term
recommendation
is to define
ground
water property rights on a per
-
acre ownership basis,
which would
attach
to the surface owner’s
real property.
Under this system, the owner
s
of the water rights would
be able to
sell
their
water as they would any other resource, and the
market would adjust the price of water to an
economically efficient level.
Most importantly, it would remove the incentive to use all you can today
, leaving
more water for the future at a lower future price.Commissioner Christi Craddick,

Social representations of mask wearing in the general population during the COVID-19 pandemic
IntroductionAlthough one of the most prominent interventions against COVID-19, face masks seem poorly adopted by the general population. A growing body of literature has found that using face masks has social meaning. This qualitative study assessed the perceptions, representations and practices of mask wearing in the general population.MethodsA qualitative survey by short semi-structured walking interviews was carried out from April to December 2021 in 11 cities in France's Pays de la Loire region. Study locations were selected for their varied geographical, social, and economic characteristics, with urbanized and rural areas. Four domains linked to perceptions of masks and wearing them were explored: (i) evolution in mask wearing, (ii) decision-making methods for wearing and not wearing; (iii) incorporating the mask into way of life; (iv) projecting into the future.ResultsA total of 116 people were interviewed. Masks marked a shift from the ordinary world to the pandemic. Overall, interviewees considered masks an obstacle to breathing, communication, and social interactions, leading to establishing strategies circumventing the mask mandate. Poor attention was paid to their medical usefulness as an obligatory clothing accessory. Mask-wearing decisions were driven by social relations, common sense, and vulnerability. The greater the feeling of security (i.e., being with close relatives), the less it was worn or worn properly, with decreased attention to others and their health. Most participants did not remember learning to wear a mask. Some were convinced that mask-wearing could not be learned (experiential knowledge). Institutions (school and work) played a central role by facilitating incorporation of masks into daily life.ConclusionsThis study emphasizes the need to reinforce the individual medical values of face masks to prevent COVID-19. Ambitious education and training programmes should be planned to learn how and when to wear masks. Institutions (work and school) may be critical for this purpose

Working paper analysing the economic implications of the proposed 30% target for areal protection in the draft post-2020 Global Biodiversity Framewor
58 pages, 5 figures, 3 tables- The World Economic Forum now ranks biodiversity loss as a top-five risk to the global economy, and the draft post-2020 Global Biodiversity Framework proposes an expansion of conservation areas to 30% of the earth’s surface by 2030 (hereafter the “30% target”), using protected areas (PAs) and other effective area-based conservation measures (OECMs). - Two immediate concerns are how much a 30% target might cost and whether it will cause economic losses to the agriculture, forestry and fisheries sectors. - Conservation areas also generate economic benefits (e.g. revenue from nature tourism and ecosystem services), making PAs/Nature an economic sector in their own right. - If some economic sectors benefit but others experience a loss, high-level policy makers need to know the net impact on the wider economy, as well as on individual sectors.
