E/C.12/COL/CO/6 refugees and internally displaced persons, so that they have access to adequate housing, productive projects and basic services such as water, sanitation, health, education and social assistance, including access to credit. The Committee also recommends that the State party take measures conducive to their safe and dignified return to their place of origin whenever possible or offer them appropriate alternatives. Population involved in the cultivation of illicit crops 53. While the Committee welcomes the measures being adopted by the State party to address the problem of illicit crops, it is concerned at the gaps and constraints that may arise at the implementation stage, from a human rights perspective (art. 11). 54. The Committee recommends that the State party continue its efforts to incorporate a human rights-based approach to the problem of illicit drugs into its strategy for implementing the Final Agreement for Ending the Conflict and Building a Stable and Lasting Peace and that it ensure that the Comprehensive National Programme for the Substitution of Illicit Crops offers alternative productive activities that guarantee the peasant farmers concerned and their families an adequate standard of living, ensuring their effective participation in both the design and the conduct of those activities, as well as real opportunities to market their produce. Adequate standard of living for demobilized persons 55. While the Committee takes note of the measures adopted by the State party to reintegrate demobilized persons back into society, it remains concerned at the obstacles to their effective implementation, particularly in rural areas (art. 11). 56. The Committee recommends that the State party adopt the necessary measures, in keeping with a human rights-based approach, to achieve the effective social and economic reintegration of demobilized persons so as to guarantee the enjoyment of their economic, social and cultural rights, particularly their right to an adequate standard of living. The Committee also recommends that the State party ensure that the so-called local training and reintegration areas afford demobilized persons access to productive activities that entail, inter alia, appropriate technical training and the active participation of the individuals and communities concerned. Right to food 57. The Committee is concerned at the prevailing disparities in relation to the right to adequate food, specifically between the critical rates of malnutrition and food insecurity and the rising number of overweight or obese persons in some regions. The Committee is also concerned at the lack of adequate measures to support peasant and smallholder farmers, which has a negative impact on the enjoyment of the right to food (art. 11). 58. The Committee recommends that the State party develop, pursuant to the National Food Security and Nutrition Policy, a comprehensive national strategy for the protection and promotion of the right to adequate food in order to address food insecurity throughout its national territory and to promote healthier diets. The Committee urges the State party to intensify its efforts to improve the productivity of smallholder farmers by facilitating their access to appropriate technologies and to local markets in order to boost incomes in rural areas. The Committee further recommends that the State party intensify its efforts to combat the effects of climate change on the realization of the right to food. The Committee refers the State party to its general comment No. 12 (1999) on the right to adequate food and the Voluntary Guidelines to Support the Progressive Realization of the Right to Adequate Food in the Context of National Food Security adopted by the Council of the Food and Agriculture Organization of the United Nations (FAO). Right to water 59.
