CONTEXT

This paper assessed the potential for agricultural development in the Colombian Altillanura, a frontier area of a middle-income country with a history of internal conflict. This region is suitable for growing diverse crops ranging from staple crops and livestock to high-valued commodities such as cacay (a nut whose oil is used in the cosmetic industry).

OBJECTIVE

The model suggested an optimal portfolio of agricultural enterprises for a representative farm that maximizes revenues net of variable costs and returns to resource endowments. Traditional agricultural enterprises were assessed, as well as some others that appear to be promising possibilities for Altillanura.

METHODS

A linear programming model (LP) was designed to support the assessment of the relative profitability of agricultural enterprises in a post-conflict era as a response for the need to reduce agricultural net imports, satisfy a growing domestic food demand and boost economic and social development.

RESULTS and CONCLUSION

A major finding was that labor shortages in the region are a key constraint for perennial crops such as oil palm, cacay, and cashew. Inclusion of mechanized crops like rice, corn, and soybean can help to alleviate this limitation, resulting in the preferred farm choice among the conventional farm activities. Integrated (Crop + Hog) operation is the most profitable among promising enterprises, but its operation size would be constrained by access to processing plants and marketing strategies. Cacay and cashew represent a viable option for farms to increase net returns using high-valued perennial crops.

SIGNIFICANCE

Currently, cattle production on native savannas is the most common agricultural activity in the region, but this model challenged this status quo by identifying other more profitable alternatives that include improved production systems for cattle, hogs, and crops.

确定边境的盈利活动：哥伦比亚的 Altillanura

语境

本文评估了哥伦比亚 Altillanura 的农业发展潜力，这是一个有内部冲突历史的中等收入国家的边境地区。该地区适合种植多种作物，从主要作物和牲畜到高价值商品，如 cacay（一种用于化妆品行业的坚果）。

客观的

该模型为代表性农场提出了农业企业的最佳投资组合，以最大限度地提高扣除可变成本和资源禀赋回报的收入。对传统农业企业以及其他一些似乎对 Altillanura 来说很有前景的企业进行了评估。

方法

线性规划模型 (LP) 旨在支持评估冲突后时代农业企业的相对盈利能力，以应对减少农业净进口、满足不断增长的国内粮食需求和促进经济和社会发展的需要.

结果与结论

一个主要发现是，该地区的劳动力短缺是油棕、可卡伊和腰果等多年生作物的主要制约因素。将水稻、玉米和大豆等机械化作物纳入其中可以帮助缓解这种限制，从而成为传统农业活动中首选的农场选择。综合（作物+生猪）经营是有前景的企业中利润最高的，但其经营规模将受到加工厂和营销策略的限制。Cacay 和腰果是农场使用高价值多年生作物增加净收益的可行选择。

意义

目前，在当地稀树草原上养牛是该地区最常见的农业活动，但这种模式通过确定其他更有利可图的替代方案来挑战这一现状，包括改进牛、猪和农作物的生产系统。
