Bill 24 – A threat to biodiversity and ecosystems associated with agriculture in BC

Bill 24 – a threat to biodiversity and ecosystems associated with agriculture in BC

buse 2010Agriculture has often been viewed as a threat to natural environments. This is clearly the case when forests are cut down to create pastures for grazing animals or fields for high value crops.  However, in a world already greatly manipulated by human activities, agricultural areas have increased in significance as refuges for organisms ranging from wildlife, birds, insects, plants, and soil microbes.  In addition agricultural lands can preserve wetlands, riparian habitats, streams, wind breaks and patches of forest.  These habitats and the organisms that dwell there benefit the agricultural industry and society in general by providing healthy, functioning ecosystems both on and adjacent to agriculture.

In British Columbia Canada, agricultural lands have been protected to some degree since 1973 by the Agricultural Land Reserve administered by the Agricultural Land Commission. Approximately 47,000 sq. km have been preserved for agricultural use either now or in the future. It has been a continual battle over the years to prevent lands from being removed from the land reserve and large tracts have been used in land claim settlements with First Nations and for a variety of development projects.  For the latter, the claim has been made that the land under contention is not sufficiently high quality for agriculture or the need for economic development is greater than the need for food security

A new threat to the ALR is currently before the BC Legislature, Bill 24.  The proposed act will make it easier for many non-agricultural uses to be developed on agricultural lands. It will seriously change the operation of the Agricultural Land Commission, and will allow changes in the classification of Agricultural lands to occur without a transparent, public process based on sound, scientifically derived information. This bill is deeply flawed and threatens the sustainability and security of agricultural production. It puts the survival of many species and ecosystems at risk. It is particularly ill timed as the future of agriculture will be greatly changed as the climate continues to warm and northern areas become more suitable for crops.

A number of ecologists have voiced their concerns about the impact of this proposed bill in a letter to Primer Christy Clark.  Their concerns are not only about the impacts on the sustainability of the agricultural industry, but also about the enormous threats to biodiversity, species at risk and the functioning ecosystems in British Columbia that would follow the reduction of the Agricultural Land Reserve. This letter is copied below.

Dear Premier Clark,

The British Columbia Government’s recently proposed changes to the Agriculture Land Commission (the Commission) Act greatly concerns many scientists for three reasons.

First, the revised changes to the governance and decision-making structure of the Commission reduces the ability for science to inform land use decisions. Second, the shift to divide the decision-making process regarding land classification into southern and interior zones will increase pressure to remove land from the reserve at a cost to the general good. And finally, the rationale for the division of the province into two jurisdictions, based simply on the value of the crops, overlooks the importance of other values associated with agricultural lands such as habitat for wildlife, endangered species, and contributions to ecosystem services.

Agricultural lands that occur in all regions of the province hold many values other than simply crop production. These areas contain wetlands, streams, ponds, riparian areas, woodlands, hedgerows, and uncultivated grasslands that are either adjacent to or integral to farm operations. These areas are instrumental in protecting functioning healthy ecosystems and in many cases, these diverse services help boost agricultural production. Many of the ecosystems encompassed by the Agricultural Land Reserve are rare in British Columbia and they provide habitat for a number of the Province’s most threatened or endangered species such as the burrowing owl, American badger, yellow-breasted chat, sage thrasher, Nooksack dace, and west slope cutthroat trout.  Other more common species that occur on Agricultural Land Reserve land are integral to agricultural production. These species range from soil microbes that sequester carbon below pasturelands, to birds such as the western meadowlarks, swallows, and common nighthawks whose populations are already declining. Species prized for hunting such as deer and elk also use so called marginal agricultural lands.  These species decline when agricultural lands are removed from production, marginal lands are converted to more intensive uses, or nonagricultural developments are permitted on agricultural lands. Allowing more nonagricultural uses on ALR land and the release of more lands from reserves will have the unintended consequence of threatening many important ecosystems and, by extension, many valuable species including species-at-risk.

Changing the current structure of the Commission to one that does not incorporate scientifically-derived information is deeply-flawed. Additionally, making changes to such an important piece of provincial legislation without consultation with the public, the agricultural industry, or scientists in general prevents relevant information and viewpoints to factor into informed decision-making. Allowing the agricultural industry to move forward with alternatives that incorporate science-based decision making within the current legislative framework are valid alternatives to altering the current reserve framework. These and other options should be explored because failing to incorporate alternate view points and scientifically derived information into the Commissions’ decision-making framework threatens the health of British Columbia’s ecosystems and endangers its biodiversity. The lack of a process to access and incorporate science-based information into the proposed framework threatens the biodiversity of British Columbia’s ecosystems and the sustainability and security of agricultural production in a changing climate.

We call upon the government of British Columbia to include scientifically derived information in the evaluation of the impacts of changes to Agricultural Land Reserve that may impact the health of British Columbia’s ecosystems and species at risk.

Sincerely,

The undersigned concerned scientists and naturalists

Research funding for women

NSERC funding by gender

Success rates are similar, but women still get less

Judith Myers UBC

NSERC has over the years provided data on request for the Discovery Grant Program for Ecology and Evolution broken down by both gender and different categories of applicants, eg. established, new first renewals etc.  In 2008, I summarized these data for presentation at the Canadian Coalition of Women in Science, Engineering, Trades and Technology (CCWESTT). This can be found as “NSERC Discovery Grant Statistics for males and females 2002 – 2008 at http://ww.ccwestt.org/Home/tabid/36/Default.aspx. That analysis showed a consistent trend for women to receive smaller grants than men with the exception of new applicants in 2007 and 2008 for which grants for women were larger.

Here, I analyze the NSERC data from 2009 and 2013. I show that success rates for grant applications are similar between men and women; however, the trend for women to receive lower grant funding on average continues.

Figure 1

Figure 1. Proportion applicants successful in 2009 and 2013 competitions.  Numbers of applicants are given in the legend. “Renewal” is first time renewal and “first” includes those applying for the first time and applicants that were previously unsuccessful in their first attempt.  Horizontal lines indicate overall average success rate, 73% in 2009 and 63% in 2013. Number of applicants is at the top of the bar.

Figure 1 shows that the overall success rate in 2013 is approximately 10% lower than in 2009, the successes of males and females are similar, and the success rate across categories is similar although first renewal success is lower and is lowest for females. Given the importance of this stage for the establishment of the future careers of these applicants this trend is of concern.

Figure 2 nserc

Figure 2. Average grants of different categories of applicants for NSERC Discovery Grants in 2009 and 2013.  The horizontal line indicates the overall average grants grant size, $33 351 (grants $5028 less for females than males) in 2009 and $31 828 ($6650 less for females than males) in 2013.

Figure 2 shows that the trend seen in earlier data continues with grants of males being larger than those of females by a substantial amount.  A factor here is that there are no female high fliers who have substantially larger grants than the average, and overall median grants are about the same for males and females. I have not taken accelerator grants into consideration here.

Given that females are on average receiving approximately $6500 less than their male colleagues, it would be interesting to know how this is translated into productivity measured as the number of publications in one year.  For an indication of how publications relate to grant sizes, I selected individuals from the NSERC results for 2013 taking from a range of grant sizes but including those with the largest grants and a sampling from the lower grant sizes.  I then used Web of Science to determine the number of publications for the year 2012-2013 for each chosen individual.

Figure 3 nserc

Figure 3. Size of grant awarded in 2013 and number of publications in 2012-2013 for an arbitrary sample of grantees. Neither relationship is significant, but that for males is influenced by the high publication number for two of the male “high fliers”.

The lack of relationship between yearly publication rates and grant size shows that productivity does not relate strongly to funding success. No female received a grant of more than $50 000 in 2013 so the range of the data is less for them.  For males, high publication numbers for two “high fliers” cause a weak upward trend in the relationship of publications to funding, but average publication numbers for four “high fliers” pulls this relationship down.  For these selected data the average number of publications for males was 10.5 and for females 9.1.  Removing the data for “high fliers” in the male data sets results in a slightly higher grant size for males than for females but only 7 publications on average for males compared to 9 for females for similar funding levels. Although this is a small and selected data set, it likely reflects the overall pattern for little relationship between grant size and publication numbers.  Similarly Lortie et al. 2012 (Oikos 121: 1005–1008) found that for the mostly highly-funded North American ecologists and environmental scientists, citations per paper were not related to increased levels of funding although for NSERC funded researchers there was a weak relationship. Fortin and Currie (2013) found that the number of papers, highest times cited, and number of high impact articles were only weakly related to NSERC funding levels for Animal Biology, Chemistry and Ecology and Evolution (PLOS ONE, DOI: 10.1371). Missing from these analyses are the data for individuals who receive no funding.  Thus the reduced proportion of successful renewals in the current funding environment, and the slightly reduced success of first time renewals are not reflected in these evaluations of research productivity. A recent study of global patterns of publications and citations shows that women publish less than men particularly in areas in which research is expensive, they are less likely to participate in international collaborations and are less likely to be first or last authors on papers (Larivière et al. 2013. Nature 504:211 – 213). There are many factors involved here.

We do not have data on HQP numbers, a metric that is heavily weighted in the NSERC Discovery Grant evaluation.  It is likely that the reduced funding level for females results in fewer HQP for them and this could have a strong impact on average funding from NSERC and publication numbers in the future.

In conclusion the new system of Discovery Grant evaluation appears to result in more similar levels of funding across categories but does not remove the bias towards larger grants on average for males. The impact on research productivity of the 37% of applicants that receive no funding as a result of the lower success rate is not easy to evaluate, but data do not support the hypothesis that higher funding for fewer individuals increases Canada’s research productivity.

Models need testable predictions to be useful

It has happened again.  I have just been to a seminar on genetic models – something about adaptation of species on the edges of their ranges.  Yes this is an interesting topic of relevance to interpreting species’ responses to changing environments.  It ended by the speaker saying something like, “It would be a lot of work to test this in the field”. How much more useful my hour would have been spent if the talk had ended with “Although it would be difficult to do, this model makes the following predictions that could be tested in the field,” or “The following results would reject the hypothesis upon which this model is based.”

Now it is likely that some found these theoretical machinations interesting and satisfying in some mathematical way, but I feel that it is irresponsible to not even consider how a model could be tested and the possibility (a likely possibility at that) that it doesn’t apply to nature and tells us nothing helpful about understanding what is going to happen to willow or birch shrubs at the edge of their ranges in the warming arctic (for example).

Recommendation – no paper on models should be published or talked about unless it makes specific, testable predictions of how the model can be tested.
