Strategic Allocation of Development Projects in Post-Conflict Regions: A Gender Perspective for Colombia

We know little about the general geographic allocation of development projects in postconflict regions, and specifically of gender-focused projects. In this study, we explore whether donor agencies prefer to work in “safe” places or dare to operate in conflict-affected zones. Using Colombia as a case study, we combine data on battle deaths from the UCDP Georeferenced Event Dataset (1994–2004) with georeferenced information on the location of development projects from the Colombia AIMS dataset (2006–2013) and manually geocode data for German-funded development projects (2012–2018) with gender as a significant objective. Using count models (N = 1120), we find a statistically strong and positive relationship: an increase in battle deaths increases the number of development projects (with and without gender-focus) in a municipality. Interaction models further reveal an amplification of this relationship for regions with a large proportion of female-headed households, as well as a high number of formally employed and literate women. A context-sensitive interpretation of our findings suggests that (1) development projects in general, and German-funded gender-focused projects in particular, dare to operate in post-conflict settings; (2) women may play an active role as community leaders and mobilizers to influence the allocation of development programs


Introduction
The number of developing countries affected by conflicts is on the rise [1]. At the same time, the amount of official development assistance (ODA) to fragile and conflictaffected countries has increased, mainly in the form of humanitarian assistance [2]. As an example, in 2017, German Development Cooperation (GDC) spent more than 60% of all bilateral ODA on conflict-affected states [3]. A growing literature examines the relationship between development cooperation and conflict. Most of these investigations operate at the country level [4][5][6][7][8][9][10]. Recently, given the emergence of highly granular data on project locations of development cooperation, a growing number of studies consider sub-national variations when investigating this relationship [11]. So far, there is no clear consensus on the relationship. While several studies find that development cooperation can increase conflict [12][13][14][15][16], this is not confirmed by other studies [17,18], or is only evident for certain sectors [19] or types of intervention [20]. Of particular interest in terms of the present study is the spatial allocation of development projects in post-conflict settings. Because little is published on project allocation in post-conflict settings, the following paragraphs discuss determinants in general.
Development actors usually decide in which country to operate, based on their political strategies, but also based on the economic needs and administrative performance of the recipient nations [21]. Several theoretical models help to explain the allocation decision. First, the recipient need model [22] suggests that donors may feel morally obligated to assist countries that experience high levels of disturbance, including violent conflicts, and Although women are less likely to actively participate in armed conflict, they frequently suffer from the indirect effects of conflict, such as with poorer health care [52]. In Colombia, about half of the more than nine million victims of the armed conflict were women [53]. Among the survivors of the conflict, many women and girls experienced sexual violence [54][55][56]. In Colombia, girls and women continue to be the most vulnerable, and are at the greatest risk of experiencing domestic violence [56,57]. Violence against women and girls emerges in the context of strong traditional gender roles within Colombian society [45]. Additionally, other characteristics such as religion, ethnicity, and sexual orientation can cause intersecting experiences of discrimination, notably by indigenous and Afro-Colombian displaced women [54,58,59].
The international community is aware of the gender dimensions of conflict. In the year 2000, the UN Security Council resolution 1325 [60] on "Women, Peace and Security" was unanimously adopted and currently forms a normative frame for sustainable development work in post-conflict contexts [47]. The resolution calls for comprehensive measures to be taken against sexualized and gender-based violence in conflicts. Moreover, it stresses the importance of women's equal participation and full involvement in all efforts for the promotion and maintenance of peace and security [61].
The Sustainable Development Goals (SDGs), which set the standards for sustainable global development, emphasize the importance of promoting gender equality (SDG 5) and the development of peaceful and inclusive societies (SDG 16) [62]. SDG 5 seeks to ensure that women and girls everywhere have equal rights and opportunities and are able to live free of violence and discrimination. SDG 16 aims to promote peaceful and inclusive societies that provide access to justice for all and to build effective, accountable and inclusive institutions at all levels. In many respects, the achievement of both goals is only conceivable in a linked way, because conflicts have gender dimensions. As such, this research is based on the notion that development projects in post-conflict regions will only be sustainable if they pay special attention to gender aspects.
Conflicts can empower or disempower women through changes in socio-cultural structures [63]. Changes in social rules and norms following a conflict provide donors with a window of opportunity to contribute to gender equality [47]. Gender inequalities are still evident in various parts of today's public life in Colombia. For example, women remain under-represented in parliament [64] and in the formal labor market and receive less income than their male counterparts [65].
Germany has committed to implementing UN Security Council resolution 1325 and has anchored the "Women, Peace and Security Agenda" in various guidelines and action plans to better reach SDG 5 by the end of 2030 [62]. With the promotion of gender equality as a central goal of German development cooperation and a guiding principle of action [66], it comes as no surprise that the majority of bilateral German development cooperation projects in Colombia between 2012 and 2018 state gender as a "significant" program objective. Given the importance of a gender perspective for post-conflict settings, our next two research questions ask: RQ2: Are development projects with gender as a significant objective located in regions that have historically experienced conflict in Colombia? RQ3: Can gender characteristics of the population explain the relationship between conflicts and the geographic allocation of development programs?

Materials and Methods
In this study, we explore the relationship between gender and placement of development projects in post-conflict regions across donors, and subsequently focus on German projects. The focus on German projects is based on theoretical and practical considerations. First, Germany is one of the primary donors to Colombia [67], with peacebuilding and conflict prevention as the most important focus alongside environmental policy and resource conservation and sustainable economic development. Germany's development cooperation with Colombia focuses on regions particularly affected by conflict [68]. More impor-tantly, for this study, compared to all other bilateral donors, Germany allocated the largest amount of funds for programs that target gender as a significant objective [67]. Second, as part of a larger evaluation of German development cooperation on supporting gender equality in post-conflict contexts [47], we were able to obtain detailed project information from the various implementing organizations which enabled us to manually geocode project location.
We obtained the geographic location of international development programs across donors from the Colombia Aid Information Management System (AIMS) geocoded data set (v. 1.1.1), prepared by AidData [29,69]. The Colombia AIMS data contains information on sectors and donors, but the georeferenced information focuses heavily on programs funded by the United States and includes only a few programs funded by the German government [70]. In the absence of a comprehensive dataset on German development aid, we manually georeferenced locations for German-funded projects, owing to the particular importance of this donor.
To identify conflict locations, we used the UCDP (Uppsala Conflict Data Program) Georeferenced Event Dataset (version 19.1) that contains the location of battle deaths for the period 1989-2018 [71,72]. The units of analysis for this study are municipalities (N = 1120), and we derived administrative boundary shapefiles from the Colombian National Administrative Department of Statistics (DANE).
To construct various socio-demographic variables, including various gender variables, we employed microdata (10% extract) from the 2005 Colombian census, the most recent census data publicly available. Census data was collected by DANE and harmonized and made available through IPUMS-International [73]. The census data contain information on the municipality of residence, which permits integration with other spatial data. Data on administrative capacity was collected by the Colombian National Planning Department (DNP) [74]. Various geospatial control variables were obtained from the GeoQuery platform, hosted by AidData, which allows aggregating raster data to the second administrative level [75]. Finally, raster data of night-time lights was obtained from the Visible Infrared Imaging Radiometer Suite (VIIRS) Day/Night Band (DNB), made publicly available by the US National Oceanic and Atmospheric Administration (NOAA) [76].
In this study, we explored whether development projects are strategically located in Colombian municipalities that have historically experienced conflicts. We employed locations of development programs from the Colombia Aid Information Management System (AIMS), geocoded and provided by AidData [69]. We selected projects with precision classes 1 to 3 to ensure that GPS coordinates were precise enough to be located in municipalities. Projects with the required precision started implementation during the years 2006-2013. For each municipality, we then counted the number of unique projects. The AIMS dataset contains, for each project, information on the respective sector. This allowed us to construct separate outcome variables for conflict prevention (CP) projects (code: 152) and projects focused on women (W) (code: 420).
Given the importance of Germany as important donor for Colombia, we geocoded projects implemented by the German Gesellschaft für Internationale Zusammenarbeit (GIZ) and the Kreditanstalt für Wiederaufbau (KfW) during the period of 2012-2018. Geocoding was performed manually, based on project documents, following the methods implemented by AidData [77] in line with the IATI standards (DFID, 2018). As part of a larger evaluation "Supporting gender equality in post-conflict contexts" [47], project documents were made available through KfW and GIZ based on a special request supported by the German Federal Ministry of Economic Cooperation and Development (BMZ). From the available projects marked as "Peace and Security" and "Gender Equality" (N = 35), we only geocoded projects for which a progress report or final report was available and implementation at the indicated location is assured. This resulted in a usable sample of N = 17 projects implemented across 74 locations. Using a Geographic Information System (GIS), we ultimately located projects within municipalities and generated our outcome variable of German-funded projects with gender as a significant objective (GG projects for short). We henceforward refer to this data as "DEval data". Figure 1 depicts unique project locations (red dots) and the number of projects implemented in each municipality (color shading) for our four outcome variables. Projects appear to cluster around large cities and in the northern regions. We conceptually understand the presence of a conflict as a subnational indicator of state fragility [14,78]. Following Weber [79], a functional state has the monopoly of the legitimate use of violence within a territory. The use of physical violence by organized non-state actors thus challenges statehood and indicates fragility.
We employed data from the UCDP Georeferenced Event Dataset. The UCDP data contains point locations for events of organized violence including the number of battle deaths. We located conflicts within municipalities and computed the total count of battle deaths over the period 1994-2004 (see Figure 2). This period can be considered a time of high-intensity conflict in Colombia. After 2004, the number of battle deaths declined considerably, marking the beginning of the post-conflict period around 2006-2007 [47]. Large numbers of battle deaths were recorded, particularly in municipalities southeast of Bogota. Achieving gender equality has been an established goal of international donors in the last decades [80], which is in line with the commitments of the international community that were anchored in the Millennium Development Goals (MDG) [81,82]. Consequently, donors stepped up gender-mainstreaming efforts, and aid allocation to gender-sensitive programs has increased since 1999 [83]. The 2030 agenda for sustainable development further advanced the importance of gender equality, with Goal 5 dedicated to achieving gender equality and empowering all women and girls while highlighting that gender equality is a main priority that should be realized across all other SDGs [62].
Donors might allocate development programs to countries with higher gender gaps in education and health [38]. Therefore, we assume that development programs that aim to contribute to gender equality should target those regions within a country in which a large fraction of the population is affected by vulnerability and gender inequalities. We employed four measures, all derived from census data, to capture vulnerability and gender-based inequalities in multiple aspects of life.
As the first indicator, we computed the percentage of female versus male household heads for a given municipality to capture vulnerable populations. Depending on the local context, female-headed households can be more vulnerable than male-headed households [84]. Colombia, for example, has witnessed a feminization of poverty in the past decades [85], especially in conflict-affected departments [86]. Female-headed households also often face multiple discriminations and are more vulnerable during times of conflict and in the post-conflict phase [87,88]. In Colombia, the proportion of female-headed households among IDPs, for example, was higher than the national average indicated by the census data [89].
To capture gender inequalities, we constructed three variables to reflect gender gaps in literacy, education and employment. Gender inequalities in education and employment are known to negatively impact productivity, economic growth and, consequently, development [83].
The choice of quantitative data on gender inequality, especially at the municipal level, is very limited, and thus we could only consider gender gaps in the areas of education and employment, using variables that are also considered essential for multidimensional well-being in Colombia [90]. The variables that capture these inequalities are constructed as ratios, where a value of 100% indicates gender balance, while a value greater than 100% indicates a higher number of females compared to males for the given characteristic. We compute the ratio of formally employed, educated (secondary level education), and literate women of working age (15-65 years) relative to the population of working-age males within each municipality. The indicator capturing formal employment indicates the access of women to the formal labor market. In Colombia, working in the formal sector is associated with several benefits, such as contributions to social security schemes [91]. Generally, women working in the informal economy tend to be exposed to more vulnerable situations [92]. The literacy indicator captures the existence of an effective primary education [93], while the completion of secondary education is a crucial prerequisite for advancing economic and social outcomes [94]. Summary statistics ( Table 1) show that significantly fewer females are in formal employment, which is attributable to their role in child-care and domestic work and employment in the informal sector [87,91,95]. The statistics in the area of education show that females have generally higher levels of education than males, a confirmed global trend [96] known as the "reverse gender gap" in education [97], which in the case of Colombia has been connected to men's involvement in violent conflict [98]. While there is some local variation, we did not observe an overall gender gap in literacy (a value of 100% indicating gender balance), which is in line with prior studies [96]. Figure 3 provides maps of the graphical distribution of all gender variables.   [71,72]; DNP = Colombian National Planning Department (DNP) [74]; GeoQuery = spatial data platform hosted by AidData [75]; NOAA = National Oceanic and Atmospheric Administration (NOAA) [76]; DRUG = DRUGDATA [99]; IPUMSI = IPUMS International census data access platform [73].
We employed a comprehensive set of sociodemographic and geographic variables to account for additional factors that may influence the allocation of development projects: administrative performance (performance index), environmental (precipitation, temperature, coca production), infrastructure (road distance, night-time lights), socioeconomic (wealth index), and demographic variables (conflict migrants, young children). Table 1 provides summary statistics and source information for all variables. Detailed information on the construction of the control variables and a correlation matrix can be found in the Appendices (Appendices A and F). Control variables were selected based on theoretical considerations and prior studies that have demonstrated the importance of these characteristics for the placement of development projects.
We modeled the count of development projects within each municipality. As the variable is characterized by many nulls, several low, and few high values, a Poisson distribution is commonly used for these types of models [13,[100][101][102]. However, tests [103] revealed that our outcome variable is considerably overdispersed (variance > mean), which can bias standard errors [104]. We therefore employed negative binomial models that incorporate a dispersion parameter theta (Θ) to account for overdispersion [105,106]. The negative binomial models take the following form (Equation (1)): Our model predicts the log (ln) count of programs (prog) for each municipality (m) located within a district (d). The parameter α represents the conventional intercept, while the coefficient β1 shows the effect of an increase in logged battle deaths on the number of development programs in a certain municipality. The model also accounts for the effects (β) of various characteristics (x) that may influence the allocation of a program to a certain municipality, including the four gender variables. We account for unobserved characteristics of districts (first administrative level, N = 32), by including district-level fixed effects (γd), and also clustering standard errors using the Huber-White method [107,108]. The district-level fixed effects also partly account for the increasing similarity of neighboring municipalities with decreasing distance. Finally, parameter e reflects the normally distributed residual variance.
When we restricted our outcome variable to a certain type of project (e.g., CP projects, W projects, or GG projects), the count of projects for each municipality declined substantially, resulting in numeric instabilities when estimating the negative binomial models. As such, we dichotomized the outcome variables and employed logit models to model the log odds of allocating at least one development project to a certain municipality, following Equation (2) [109].
In this study, we assumed a unidirectional causal relationship between battle deaths and development projects. While in some cases it may be possible, we considered it unlikely in the Colombian case that the placement of development projects caused an increase in battle deaths [5,6,110]. More importantly, the count of battle deaths (1994)(1995)(1996)(1997)(1998)(1999)(2000)(2001)(2002)(2003)(2004) predates the post-conflict period during which development projects started their implementation (2006-2013 for AIMS data; 2012-2018 for DEval data). Based on this clear time order, we assumed a unidirectional causal relationship in which battle deaths influenced the placement of projects (battle deaths -> project placement). The use of a comprehensive set of control variables allowed us to further condition the observed relationships in an attempt to approximate causality.

All Projects
As the first step of our analysis, we attempted to answer the research question (RQ1): Are international development programs located in regions that have historically experienced conflict in Colombia? Our negative binomial regression models, using "all projects" as the outcome variable, reveal a positive relationship between the log count of battle deaths and the number of development projects (Table 2). Model 1 includes only battle deaths, model 2 adds gender variables, and model 3 includes the full set of control variables. For a focused results exposition we do not discuss coefficients of control variables.
For the gender variables, only employment is significantly associated with the placement of development projects. Specifically, a 10% increase in the number of females versus males in formal employment increases the number of development projects in the average municipality by 1.2 (b = 0.14; p < 0.05).

Projects with Gender as a Significant Objective
In the next step of our analysis, we focus on specific types of projects to answer our second research question (RQ2): Are development projects with gender as a significant objective located in regions that have historically experienced conflict in Colombia? We estimated three separate models for conflict prevention (CP) projects (Model 1, AIMS data), projects focused on women (W) (Model 2, AIMS data), and German-funded projects with gender as a significant objective (GG) (Model 3, DEval data). The results (Table 3) show that CP projects tend to be located in municipalities for which a high number of battle deaths were reported (b = 0.65; p < 0.001). This model serves as a positive control as we would expect the placement of conflict prevention projects specifically in conflict-prone regions.  For both, W projects (b = 0.19; p < 0.01) and GG projects (b = 0.37, p < 0.01) we also observed a statistically significant positive relationship. An increase of battle deaths by one log unit increases the odds of observing a German-funded development project with gender as a significant objective being placed in the same municipality by 45% ((exp(0.37) − 1) × 100).

Interactions
In a final analytical step, we addressed our third research question (RQ3): Can gender characteristics of the population explain the relationship between conflicts and geographic allocation of development programs? To answer this question, we used interactions between battle deaths and the four gender variables ( Table 4). As a first observation, the placement of CP projects in post-conflict regions does not seem to systematically vary conditional on the gender context, as evident from insignificant interaction terms. However, conditional effects do emerge for all projects, W projects, and are suggestive (marginally significant) for GG projects. To illustrate these interactions, Figure 4 depicts predicted probabilities when interacting the percentage of female household heads with battle deaths.   Table 2 (not shown for improved readability) and include department-level fixed effects; battle deaths were log-transformed to approximate a normal distribution; variables involved in the interactions were grand mean centered; a Coefficients reflect an incremental change of 10 units; All projects: Negative binomial models; conflict prevention (CP) projects, women (W) projects, and Germanfunded projects with gender as significant objective (GG): Logit models; CP and W projects started implementing during the years 2006-2013; GG projects started implementing during the years 2012-2018; conflict data for years 1994-2004; + = p < 0.1; * = p < 0.05; ** = p < 0.01; *** = p < 0.001. Figure 4a reveals an overall positive relationship between battle deaths and the predicted counts of all projects in a municipality (50% ile). The three lines indicate that the strength of the relationship (slope) is conditional on the percentage of female heads living in the given municipality. In municipalities with few female heads (10% ile), the slope of the line is flat, suggesting a weak relationship. Yet, as the proportion of female heads increases, the relationship (slope) becomes considerably more pronounced (e.g., 90th percentile).
This conditionality is even stronger for W projects (Figure 4c). Only in regions with many female household heads (90th percentile) do we see a strong positive relationship between the number of battle deaths and W projects. As such, projects focused on women do not gravitate towards post-conflict regions in general, but only when a high proportion of female heads is present in the communities. We observe similar significant positive interaction terms for the gender variables "women employed" and "women literate". The positive relationship between battle deaths and W projects becomes much stronger as the proportion of women (relative to men) formally employed and literate increases in the municipality.

Robustness Tests
We performed a number of robustness tests to explore the sensitivity of our results. While the choice of models was based on the nature of the outcome variables (counts), it is possible to use more simplistic OLS models. While OLS models can produce valid results [112], their use is discouraged for count data with low mean values [113]. Moreover, OLS models would allow predictions of negative values, which is inappropriate for count variables of exclusively positive integers as in our case. Nevertheless, as a robustness test, we employed an OLS approach to estimate models of Tables 2 and 3 (Appendix B, Table A1). The effects of the primary predictor (conflict) remain similar in direction and significance, demonstrating the robustness of our findings to the choice of the model. We selected the set of control variables based on their relevance to project placement, as suggested by theory and empirical studies. In addition to these theoretical considerations, we apply the method proposed by Oster [114] to assess the robustness of our models to unobserved variable bias. We find only a small change in the coefficient of the primary predictor (battle deaths) when adding control variables, accompanied by a substantial increase in R-squared. The Oster test suggests that unobserved variables would have to be almost five times (δ = 4.8) as important as the observed variables for the effect of the primary predictor to drop to zero. This indicates that bias due to unobserved confounders is highly unlikely.
The AIMS data provide information on the monetary value of commitments for each project. While for our main analysis we preferred to use the number (count) of projects per municipality, we also estimated OLS regressions using commitments as outcome variables. The results from the commitment models (Appendix C, Table A2) are highly similar to the results from the project count models, indicating an increase in aid spending in regions most affected by conflict.
In the main analysis, we use the 10-year period of high-intensity conflict from 1994-2004. To investigate if a change to the length of this period affects our results, we used all available battle deaths information in the UCDP data for the period from 1989-2018. Re-estimating the models of Table 2 using this alternative predictor produces very similar results, further confirming the robustness of our findings (Appendix D, Table A3).
To investigate potential impacts of influential cases, a jackknife type procedure was performed, removing a random selection of 10% of all municipalities (N = 1120) from the sample and re-estimating the models following an established procedure [115,116]. The resampling was performed 1000 times and the percentage of significant results was recorded. We varied the number of randomly omitted municipalities between 10% and 30% (Appendix E, Table A4). These tests demonstrated that the obtained results are highly robust and not caused by outliers.

Discussion and Conclusions
In this study, we have investigated the relationship between the location of development intervention projects and conflict in Colombia. The observed results for development projects, in general, are in line with our theoretical expectations, and with recent observations, suggesting an increased development activity in post-conflict regions [117]. As an example, the Colombian peace process provided an incentive for implementing more programs to reintegrate ex-combatants and to prevent future conflicts [118,119]. We also find more development projects in regions with higher numbers of women formally employed. Likely, this relationship reflects the efforts of many development projects to support vulnerable populations such as displaced women [58,120], with positive effects on the female employment rate.
Moreover, our results confirm that projects with gender as a significant objective tend to gravitate towards post-conflict regions. This observation can be explained by donor priorities of funding programs to support female war victims [58,[121][122][123] and to promote peace through female empowerment [44,124,125] or by efforts to contribute to the implementation of UNSCR 1325 [126].
Finally, the observed interactions suggest that the placement of development projects in post-conflict regions is strongest in the presence of a large number of female-headed households, as well as in high formal employment and literacy rates for women. Rather than telling a story of vulnerability, these findings hint at increased female activism and power. Literate and formally employed women are in a much better position to lobby for the placement of new development projects in their respective communities [127,128]. Indeed, women in Colombia have demonstrated strong community engagement, often supported by international development programs [45]. Moreover, women have been at the frontline of countrywide peace movements, uniting in large multi-ethnic groups to raise their voices for gender justice throughout the peace negotiations [44,129]. Here, they ensured that gender issues were included in the peace treaty to prevent the replication of male dominance [130]. As such, the observed conditionality may be explained by a culture of strong female leadership, self-organization, and lobbying for the placement of development projects in certain regions [44,45,125,131].
While thoroughly conducted, this study is not without limitations. First, data limitations prevented us from using information on gender-based violence from Demographic and Health Surveys (DHS). Future research may use sophisticated geospatial interpolation techniques to estimate these gender characteristics for municipalities in which the DHS survey was not fielded [132].
Second, we drew on the available published literature to explain the conditional relationships within the context of Colombia. Future research may employ qualitative methods such as interviews and focus groups to provide a better understanding of the mechanisms that amplify the project placement in post-conflict regions in the presence of a large number of female household heads, and a large proportion of employed and literate women.
A gender focus in post-conflict recovery programs can be beneficial for several reasons. Women and girls were severely affected by the conflict [56,59,89,131,133], resulting in comparatively high levels of forced internal displacement [89,133]. Violent conflicts often claim the lives of husbands and fathers, leaving behind mothers and daughters who are at increased risk of poverty and marginalization [134][135][136]. As such, the international development community could build on the trends observed in this study and further strengthen the gender focus in post-conflict recovery programs in line with the recommendations of the United Nations Security Council Resolution 1325 on women, peace and security [60].
The pertinent literature and our findings suggest an active role in advocacy and lobbying by strong Colombian women who act as community mobilizers [44,45,125,135]. Yet, in the spirit of "leaving no one behind" [62], donor agencies could increase their implementation of gender-focused projects in post-conflict regions that are characterized by limited education and literacy of females. These locations likely lack the female leadership and lobbying activities that tend to attract the support of donor agencies and, as a result, may be neglected in the distribution of program resources.
In sum, an increased focus on women's needs [134], but at the same time recognizing women as important allies and partners [137], will allow the international development community to implement the UN Security Council resolution 1325 and to more fully advance the Agenda 2030 targets [62] for gender equality (SDG #5) and peace, justice and strong institutions (SDG #16), as well as to further the equal treatment of all human beings, even under the harsh societal conditions faced by those in conflict or post-conflict settings.

Conflicts of Interest:
The authors declare that they have no conflicts of interest.

Appendix A
Mediator and control variables employed in the main text were constructed as outlined in the following paragraphs: Administrative performance. Project placement takes place within the nexus of potentially conflicting donor priorities: seeking to assist the neediest but finding it more effective, and therefore preferable, to work with capable administrations [22,29,138,139]. In this study, we attempt to capture these tendencies with the index known as Desempeño Integral Municipal, which constitutes a comprehensive assessment of the administrative performance of each municipality [74]. The index reflects the equally weighted mean of four indicators: administrative effectiveness, administrative efficiency, compliance with legal requirements, and quality of management. The index is available for the years 2006-2017, and we calculated the mean to reflect average performance across time.
Environment. Development projects may be systematically allocated due to specific environmental conditions. For example, in line with the recipient need model, climate change adaptation programs may target regions particularly vulnerable to flooding or droughts [140,141]. Yet, other factors may influence this relationship. For example, conflict migrants may settle in structures and regions particularly vulnerable to environmental impacts (e.g., make-shift housing on steep hillsides) leading to an increased need for development interventions [142,143].
To capture differences in climatic impacts, we use a measure of annual average precipitation (mm) and annual average air temperature ( • C) for the year 2017 derived from gridded data (50 km spatial resolution) compiled by the University of Delaware [144] and available as municipality aggregates via AidData's GeoQuery [75].
Coca production. Colombia's extensive coca economy has been key to sustaining military conflict, notably in FARC-controlled regions [145]. In the major coca-growing areas, violence tends to be higher compared to non-producing regions [146,147]. At the same time, coca cultivation often relies upon the labor of rural women, who, despite increasing security threats, often benefit economically [148]. In this context, development programs seek to provide these women with alternative livelihood options to ease their dependence on illicit crop production [149,150]. Given the connection between coca production, conflict, and development projects, we make use of data on coca production sites for the period 1980-2002 generated by Buhaug and Lujala [99]. We constructed a dummy variable, differentiating between municipalities in which coca was produced (coded 1) and municipalities that did not have coca production (coded 0).
Infrastructure. In development studies, access to quality infrastructure is widely recognized as fundamental in achieving development targets such as economic growth and reduced inequality [151]. In this study, we account for the level of infrastructure development using two measures: (1) the distance to the next road, and (2) nightly luminescence. The distance to the next road (in km) was computed based on the Global Roads Open Access Dataset (gRoads) version 1.0. [152] and aggregated to the municipality using the GeoQuery system [75]. Gridded data (spatial resolution: 15 arc-seconds or 300 m) of nocturnal luminescence (night-time lights) from the Visible Infrared Imaging Radiometer Suite (VIIRS) Day/Night Band (DNB) is publicly available from the US National Oceanic and Atmospheric Administration (NOAA) [76]. We employed the cloud masked, outlier-removed composite data (vcm-orm-ntl) for the year 2016. Values were aggregated to the municipality level and reflect luminescence in nanoWatts/cm 2 /sr. Prior research has used night-time lights to approximate economic growth and urbanization [153][154][155][156][157].
Socioeconomic context. Poverty alleviation is an important goal of development programs [24,141]. Assessments on resource allocation have demonstrated that poor regions and countries do indeed receive the largest aid inflows, although political interests also influence donor decisions [21,26,139,141,158].
To capture the overall socioeconomic status of a household, we constructed an additive wealth index in line with prior work [159,160] based on census microdata. We first performed a factor analysis (rotation: "varimax") with 18 variables. Using a cut-off threshold of 0.4 eigenvalue, we identified nine variables that best reflect the latent construct of "wealth". These variables measure the structural quality of the housing unit (material of floor, number of bathrooms), the type and quality of services available at the residence (type of cooking fuel, toilet type, trash collection, access to electricity, access to piped water), as well as the possession of appliances (refrigerator, TV). We combined these variables to an additive wealth index (Cronbach's alpha = 0.88).
Demographic characteristics. Colombia shows one of the highest rates of internally displaced people worldwide [161]. Displaced populations are highly vulnerable, often poor, and frequently lack access to basic social services [88]. It is therefore not surprising that numerous development programs in Colombia target people displaced by violent conflict [162][163][164]. Using census data, we constructed a variable that measures the proportion of conflict migrants (migration due to violence or insecurity) in each municipality. Prior research has used this variable to evaluate the impacts of forced migration on female empowerment [165] or to examine Colombia's internal migration patterns over the turn of the century [166].
Young children, in particular, have been suffering from the consequences of violent conflict in Colombia and have frequently experienced insecurity and emotional and physical abuse [167][168][169][170]. In response, several development agendas specifically target children's well-being in fragile contexts [171,172]. As such, we expected to find a larger number of development projects in regions with a high proportion of young children. We, therefore, constructed a variable based on census data that reflects the average number of young children (age < five years) per household within a municipality.
Initially, we included a measure for population density in our models, based on the assumption that projects may be more frequently located in populated regions. Yet, due to high correlation with our measure of night-time lights, we were unable to include both variables in the same model and decided to omit population density.

Appendix B
To investigate the sensitivity of the effects of conflict on project placement to the choice of the model, we estimated all models using OLS models. The direction and significance of the observed effects are similar to the results of the negative binomial and logit models, demonstrating the robustness of the observed effects to the choice of the model.  Tables 2 and 3 of the main text; a Coefficients reflect an incremental change of 10 units; + = p < 0.1; * = p < 0.05; ** = p < 0.01; *** = p < 0.001.

Appendix C
To investigate the sensitivity of our results to the specification of the outcome variable, we use the US dollar value of total commitments instead of the count of development projects. Table A2 shows results from OLS regression models. Notes: Same model specifications used as in Table 2 of the main text; a Coefficients reflect an incremental change of 10 units; * = p < 0.05; ** = p < 0.01; *** = p < 0.001.

Appendix D
In the primary analysis of this study, we use the period 1994-2004 to capture highconflict intensity. To investigate the sensitivity of our analysis to changes in this period, we used the entire period from 1989-2018 for which battle-related deaths ("battle deaths") are recorded in the UCDP database. Results from negative binomial models are shown in Table A3. Notes: Same model specifications used as in Table 2 of the main text; a Coefficients reflect an incremental change of 10 units; + = p < 0.1; * = p < 0.05; ** = p < 0.01; *** = p < 0.001.

Appendix E
To investigate the effect of influential cases on our results, we performed a Jackknife type resampling procedure. Omitting a random sample between 10% and 30% of all municipalities and re-estimating the models 1000 times produced the following table (Table A4). The table records the percentage that a significant coefficient for battle deaths (% sig) was returned when repeatedly re-estimating the model.  Tables 2 and 3 of the main text; Control variables not shown for improved focus of the table; + = p < 0.1; * = p < 0.05; ** = p < 0.01; *** = p < 0.001.
The results show that for all projects and conflict prevention (CP) projects the significant relationship with battle deaths stayed significant 100% of the time. For projects focused on women, (W) the coefficient reached significance in 77% of the model estimates and for German-funded gender-focused projects it reached significance in 94% of the estimates, indicating an overall high level of robustness of the estimates.
