Abstract：

• AGD aims for a green environment, sustainable agriculture and clean water.

• Presenting examples of the impact of agriculture on water quality.

• Presenting examples of solutions for sustainable agriculture and improved water quality.

• Integration of livestock and cropping systems is possible on a farm or among farms.

• Providing recommendations for further development of sustainable agriculture.

Crop and livestock production are essential to maintain food security. In China, crop and livestock production were integrated in the past. Today, small backyard systems are still integrated but the larger livestock farms are landless and largely geographically separated from crop production systems. As a result, there is less recycling of animal manures and there are lower nutrient use efficiencies in the Chinese food production systems. This, in turn, results in considerable losses of nutrients, causing water pollution and harmful algal blooms in Chinese lakes, rivers and seas. To turn the tide, there is a need for agricultural “green” development for food production through reintegrating crop and livestock production. An additional wish is to turn the Chinese water systems “blue” to secure clean water for current and future generations. In this paper, current knowledge is summarized to identify promising interventions for reintegrating crop and livestock production toward clean water. Technical, social, economic, policy and environmental interventions are addressed and examples are given. The paper highlights recommended next steps to achieve “green” agriculture and “blue” water in China.

Fig.1 Overview of crop and livestock production in relation to water pollution in China today (a) and an optimistic future with interventions to develop green agriculture and thus contribute to “blue” (clean) water in the future (b). Interventions are shown in Fig. 2 and discussed in Section 3.

Fig.2 Five categories of intervention for reintegrated crop and animal production toward clean water. The five interventions are technical, social, economic, policy and environmental. Examples are given for each intervention (see the main text for more information and the definitions of the interventions).
